In the field of volume flow control assemblies, Flomax a pivotal flapper type closure element always present in flow volume custom designed to operate inside round flow assemblies, constructed in geometric accordance to its embodiment's inside diameter curvature when in full bore.

Current pivotal closure elements currently operating round flow assemblies internally are constructed as a complete unit including additional design to provide the closure element's absence from the flow in full bore. Other designs with a pivotal point location centered in high flow volume area creating flow restriction and disturbance increasing back pressure.

In previous similar patents the correction has been a larger embodiment design resulting in a manufacturing process requiring separate pieces to be assembled with little changes in reflecting the closure element's geometrical environment.

The inclusion of Flomax's constructed geometrical body design, in a full bore position provide function specifics features as in full contact of its embodiments' inside perimeters curvature surface concluding to a flow volume restriction of its total thickness. Within its fixed single pivotal point travel rotation in operating its required function, tolerances from all flow volume control positions from open to close are in accordance to its round embodiment's circumference dimensions in reference to FLOMAX's body surface area.

According to its function, the flow assembly in which it serves can be used as FLOMAX's housing body and matting surface area as the back seat to the required seal.

In the provision of function specifics mechanical linkages, anchoring point restraint system, engineered specifications to its application, FLOMAX can be inserted thru the entry of the embodiments' flow assembly including angle fittings of the same diameter.

FLOMAX's applications of uses;

-Volume flow control, -single flow direction, -flow closure, -flow diversion.

Description: FLOMAX built as to regulate or control flow volume, comprises of a pivotal flapper type closure element used in any round flow assemblies, constructed of a material compliant to its environment, fitted with the required seal to the application of use. With a body shape design specifications as always present in flow volume, in open bore position, FLOMAX's geometrical body form Is in accordance with the inside perimeter of ifs serving flow assemblies' rounded embodiments' curvature as in parallel relations, concluding to FLOMAX's full body contact position providing flow volume restriction specifications calculated from the bodies' thickness surface area of FLOMAX's constructed materials or the required seal thickness if greater, as in parallel position of flow volume. Upon FLOMAX's function application of choice, with its identical curvature shape of its inside diameter round flow assembly embodiment when fully open, FLOMAX's constructed body surface area is increased to accommodate the required closing angle position, if decreased from 90 Degree as to function required specifications. As shown in fig 5 If the body surface area dimensions is constructed as to a closed angle position of less than 45 Degrees, from a single fixed pivotal point location or with a mechanical linkage to the same effect, FLOMAX's travel operating movements between its open and closed positions, are all within its serving round embodiment's inside constrictions providing a full seal when closed and full contact in open bore to its serving flow assemblies' inside curvature.

In FLOMAX's constructed body dimensions as being closed at an angle position higher than its optimum 45 Degree, the removal of protrusions is necessary to provide its travel Function to operate, caused by its diagonal longitude length deriving from its body curvature shape when in motion of operating between open and closed position, compensated by the required seal specifications to provide a full sealed closure. As the protrusions shown in figure 3 In the use of single flow direction by a self operated buoyancy specifications, FLOMAX's constructed body design is to include the absence of interior material substituted with stiffening interior ribs creating a sealed shelled chamber area providing buoyancy In a location of choice as to operate in combination with an opposed mirrored partial or full body component attached at the diameter location as one, allowing pivotal travel movements within the embodiments inside perimeter's tolerances as to function. As shown in fig 4 In function specifics applications, an offset pivotal point location, sidewall slots travel guides built into its embodiment as a sliding mechanism or a mechanical linkage in the provision within its travel constrictions can be used as to allow a greater variance of options in specifications to choosing the applicable seal types compliant to specific environments and functions of operation. As shown in fig 1 Such conditions as FLOMAX's installation thru entry of flow volume possible into existing round flow assemblies as a addition to as per built without flow control or providing FLOMAX an embodiment as a complete unit, the suitable seal of choice reflects FLOMAX's perimeter specification detail construction to ensure seal restraint and its body thickness as the seal's mating surface area reflects the identical angle surface as the serving embodiment's inside perimeter's curvature mating surface. The addition of a perimeter stiffening rim requirements maybe necessary from a choice of seal type specifications in operating to its designated use. As shown in fig 5 Flornax

Technical field:
