NON-INTERCHANGEABLE CONNECTION VALVES FOR FUEL BARRELS Russian patent published in 2012 - IPC F16K21/04 

FIELD: machine building.

SUBSTANCE: non-interchangeable double-component connection valve is described to connect a source of fuel to a fuel element or another device. The valve comprises the first and second part of the valve. The first part of the valve comprises a valve body, a sealing element and a middle stand. The middle stand is connected to the valve body so that the middle stand is in general fixed relative to the valve body. The sealing element is placed at a certain distance from the contact surface of the first part of the valve, and there is a space on the contact surface around the middle stand. The space has dimensions and is calibrated so that it holds a thin-walled pipe of the second part of the valve. Each thin-walled pipe presses onto the first part of the valve, it moves the sealing element to a certain distance from a sealing position for development of a flow through both parts of the valve.

EFFECT: improved valves, which make it possible to discharge gas, to maintain tightness, to improve fuel movement through a valve.
