AUTOMATIC GAS INTAKE AND EXHAUST VALVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/037341
Kind Code:
A2
Abstract:
The present invention relates to an automatic gas intake and exhaust valve device comprising: a main body part having an orifice hole on one side and having a gas intake and discharge hole on the other side; an opening and closing member which is movably inserted in an unconstrained fashion inside the main body and which opens and closes the gas intake and discharge hole; and a connecting member which is formed extending on one side of the main body part and connects the main body part to normal tubing so as to allow passage between the same; wherein the opening and closing member floats and so closes the gas intake and discharge hole due to the speed of flow of a fluid when the fluid flows from the tubing, through the orifice hole and into the main body part and is discharged through the gas intake and discharge hole, but drops towards the bottom of the main body and in so doing opens the gas intake and discharge hole due to its own weight if the level of the fluid which has flowed into the main body part is lowered, thereby automatically taking in and discharging air inside piping or installed equipment.
