FIELD OF INVENTION

The present invention generally relates to a valve. More particularly, this invention relates to conical valve which are comes under the precision flow system of the any fluid. More specially, the disclosed valve system is designed to use in the fuel injection system for pressurised fuels in engine systems.

BACKGROUND OF THE INVENTION

Generally, in many industries and in different fields fluid valves are utilized to control a flow of a working fluid through a system of pipes. The valves are utilized to open and close fluid communication between two points within the system. There are many types of valves that exist, such as a ball valve, a gate valve, a butterfly valve, a globe valve, etc.

In day-to-day life number of consumers are dealing with a pressurised fuels which are nothing but fuels like hydrogen, Liquified Petroleum Gas (LPG) and different types of gases such as nitrogen, oxygen caron dioxide. Apparently liquid oxygen that is cryogenic in nature. Moreover, all these gases are in a gaseous condition at NTP but are filled in the cylinder and compressed under pressure which remain in liquid condition inside the cylinder. To maintain the constant pressure specific valves are used which having different configuration and specifications and structure where more or less the function of all these valves is same. However, the working principle, reliability and its operation of the valves varies accordingly from its structure and working conditions of the fluids. Therefore, there is a need of a valve which can achieve most of its functions at the same time it acts as an accelerator for the pressured liquids or fluids.

The various types of valves typically include a housing and a seat. In high pressure applications, the housing and seat are often manufactured from a metal material. Accordingly, movement of the seat to open and close the valve moves the metal seat against the metal housing. The large forces acting on the valves generate a high-friction load on the seat during movement of the seat. The high friction between the seat and the housing, in combination with the metal-on-metal interface between the seat and the housing, may potentially damage the seat. In results the functionality of the valve gets decreases over the period of time and after some time there is a high chance of leakage in the valve. Therefore, due to its poor design and inefficient sealing mechanism most of the regular valves are not reliable for long lasting usage. Additionally, most of the valves typically require an actuator, such as a handle, rotary knob, motor, etc., to operate the valve. For high-pressure working fluids, the actuators become large which are greatly increasing the overall size and cost of the valve.

In piping and storage systems of any fluid valves are an essential device or equipment. In any gas or liquid flowing systems (including gas pipelines, gas pressure tanks) without valves flow management and control of the fluid cannot be possible. Presently, the valve body sealing surface and the valve sealing surface of these valves are both flat and cooperate to form a plane seal. In an assembly of the valve the sealing block is fixed on the valve sleeve by screws and nuts. According to applications and its requirements these valves are categorised in different types but the principle of opening and closing of the sealing body is same. When these valves are used several cycles over the period of time the sealing surface of the valve disc is pressed out of the dent or groove and the provided sealing may damage it valve becomes prone to leak. In addition to that there are chances for the nut of the fixing sealing block may loosen off or fall off which may cause the sealing block to fall off and causing the sealing failure. Therefore, there is a need of perfect sealing mechanism which can achieve perfect sealing and zero leakage in valve without fail.

In order to meet the needs of high-pressure valves and ultra-high-pressure valves, the existing technology mainly uses hard cone seals, but these hard cone seals are difficult to manufacture or produce for such kind of seals by some basic machining operations. For making a perfect seal it requires high precision tools and machineries which are more expensive for mass production. The most important thing is that if the sealing mechanism is not manufactured without precisions, then it cannot achieve zero leakage. Due to improper sealing mechanism these valve gives poor performance, especially when it is used for controlling gas, then the leakage problem is particularly serious.

CN112282883A discloses the valve conical surface positioning device which comprises a valve conical surface, a valve rod, a valve conical angle, valve guide pipes, a valve positioning cylinder, a valve cavity, a valve conical surface clamping ring, a valve conical surface base and a rotary valve rod.

The disclosed utility model is configured with tubular housing, conical piston assembly, bushing nut, knob, spring, seal on the cone piston, at least one seal and threaded cap. In an embodiment of the present invention the disclosed conical valve is configured or assembled with a tubular housing, conical piston assembly, bushing nut, knob, seal on the cone piston, ring seals, threaded cap.

In an assembly according to the arrangement of the Conical Piston Valve, tubular housing is provided which is made up from a metal tube housing having threaded portion provided on both ends thereof for fitting into the cylindrical body and the threaded cap which is connected to the inlet and outlet of the pipe. In this specific arrangement on one of the sides of the tube there is an inlet hole provided which opens on the bottom of the taper as shown in the figure. There is threading arrangement is provided on the outer diameter of the tubular hosing body and threading arrangement provided on inner dimeter of the cylindrical body for tightly fitting arrangement. In Conical Piston Valve the conical piston assembly is provided, this assembly includes conical piston having a cone at one end and it is flat on the other face. The conical piston is connected with the straight shaft at the center which shows as an extension of the conical piston. The rear part of the conical piston acts as a pushing rod acts like injection syringe, which also has grooves provided for fitting seals. In this conical piston assembly, the OD (outer dimeter) of the pushing rod is slightly larger than the OD (outer diameter) on the tapering piston. Due to this specific arrangement the conical portion remains hanging in the air inside the tube while the rod is touching the internal diameter of the conical cylinder. When the shaft slides back and forth, the conical portion of the conical acts in a telescopic fashion. Further, in this conical piston valve assembly, a trapezoidal cavity is provided for fixing the seal with threading at the centre as shown in the figure. From the centre there is threaded extension which can be fitted into the front part as shown in the figure. On the other side of the facing there is an extension shaft. In this assembly the inside part for taper cone of the tube is absolutely identical to the cone of the piston and they are acting as a male and female joint when fully inserted.

In an embodiment of the present invention in sealing mechanism is achieved when the conical piston gets fitted in the conical cylinder section tightly, it gets fixed onto the entry hole on the taper zone and it does not allow any gap for fluid to escape. It can be said that proper sealing is achieved in the valve body and it is in completely closed position. Since the cone piston is rested on the area from all sides, it can bear high pressures without any deflection.

Furthermore, in this conical valve assembly of the system bushing nut is provided which is a nut having threading on OD (outer diameter) is equal to the ID (internal diameter) of the tube and having a bushing at the centre as shown in the figure. In this assembly a knob is provided at the end of the shaft for handling for the purpose of opening and closing the valve position. In this assembly there is a spring provided which is mounted on the shaft which is situated between the facing of the cone and the bushing nut. Additionally, in this assembly there is a seal provided on the cone piston which is a synthetic seal and it is having round shape on the OD (outer diameter) as shown in the figure. The width of the seal is purposefully kept more than the OD (outer diameter) of the entry hole i.e. land for sealing is provided for seal proof structure so it can prevent most of the leakages from the system. In this assembly there is ring seals are provided in the grooves on the pushing rod for better and snugly fitting of the elements of the system. Moreover, in this assembly there is a threaded cap provided on tubular housing with delivery hole extension at the end of one side as shown in figure.

By adopting the above technical solution in the constructional arrangement of the disclosed device when the valve in (closed position) the centre line of the piston goes along the Y- axis and it moves in that action only i.e., along the same axis. In this way, the Y-axis remains a steady axis, while the entry hole centre line goes along the X-axis and it also remains a steady axis means without changing its original positions it moves only along its axis. In another condition both the axis intersects each other at the centre and that is determined by the X - axis and the point of intersection. When the valve is in its closed position, the point of intersection of the two axes shows the point of original origin of the axis. However, when the cone starts traverse along axis from the origin, the centre of the origin starts shifting its position without changing its axis, i.e., Although there is a change of origin of the axis but only along Y axis. In this scenario it is moving in only one direction.

In the whole procedure of this sealing mechanism along with X-Y movements there is a third axis or a curved plane of a cone. The line of the cone moves or traverse in a third axis and this line of cone goes away from the centre line of the female cone or comes close to the extent of zero to the line of female cone and when conical male and female are fixed tightly together there has to be a zero gap by the rule of geometry, that implies zero leakage when valve is in closed position. Additionally, in closed conditions the conical piston is covered by the trapezoidal valve of conical cylinder which gets support from all sides, i.e., on the entire area, having absolutely no chance for conical piston to move even a micron anywhere at any pressure. Henceforth, a proper closed condition of the valve is achieved.

Working Principle

When fluid is enforced in the valve through an entry hole and when the valve gets into the operation i.e., when it starts opening, the 'taper wall' on the piston (specific curved plane) starts going away from the entry hole on the taper wall of the female cone. This condition is achieved when it starts creating the gap between the male and female elements. The width of this gap gets changed with the movement of the piston. In the design of this assembly whatever is happening, inside the enclosed cylinder is shown by a special device is made.

In order to more clarification and better understanding a special device is introduced in to study the working of the assembly inside of the cylinder which shows figure the cross section of the assembly while working. From this it can be understand that the gap will be in a circular fashion inside the tube. This gap represents a perfect circular band. The rate of the delivery of fluid is directly proportional to the width of this band. This band is created at the edge of the end of the facing of the piston. When this facing moves along the Y axis inside the cylinder, the circular band which is a delivery window also shifts along with it simultaneously. Therefore, the style of the gap behaves in a particular fashion which results in causing of this function. So, the function is reduced by the fashion.

Because of the piston movement there is a shift of origin along Y axis which happens continuously in a particular manner. Hence if the area of the band is known then the radius of an aperture which would be an acting aperture at the time of delivery. The circular band is acting as a very window, (deduced) The area of the band is equal to a radius of acting aperture of that position at that time and this radius obviously can be calculated (simple geometry). This clearly means if the width of the band changes the area of window changes. The size of the delivery aperture can be pre decided and controlled at the time of functioning precisely with the Geometrical Matrix.

In an application of the conical valve of the system right from the start of the opening of the valve, even with the displacement of one micron which can be functionally operated and visually observed, fluid can enter because it is under pressure (pressurised fluid). When the fluid gets enforced entry from the entry hole, it goes all around in the gap happening between the male and female. Therefore, the rate of fluid delivery is directly proportional on the width of this gap which is in the perfect round form will appear like a circular band.

The rate of delivery (litres - measure in volume) can be measured by measuring the dimension in distance i.e. in 'Length' along axis and hence can be easily controlled with the shift of piston movement. It seems that the key of the matrix of the function goes along the shift of origin that can show a definite graph which can help for designing future atomisation and software.
