BLOWER VALVE WITH SAFETY VALVE FUNCTION Russian patent published in 2019 - IPC F16K15/06 F16K15/20 

FIELD: machine building.

SUBSTANCE: invention relates to an inflation valve with a safety valve function. Valve contains: a housing, a cover and an internal operating unit of the inflatable check valve. Valve body contains an upper air chamber and a lower air chamber, which communicate with each other through the second valve hole. Valve cover for covering the upper air chamber is detachably connected to the valve body, and the internal working unit of the check valve is located in the second valve hole. Concave outlet chamber is located on the upper surface of the valve cap, and the first valve hole is formed on the lower surface of the outlet chamber, which communicates with the upper air chamber when the valve cap is tightly screwed onto the valve body. Internal working unit of the exhaust check valve, which seals the first valve hole in the normal position, is located inside the exhaust chamber. Valve cover can lead to the opening of the internal working assembly of the inflatable check valve when the valve cover is tightly screwed onto the valve body, with the result that the upper air chamber and the lower air chamber communicate with each other.

EFFECT: technical result is to reduce the cost and simplify the design, due to the fact that the inflatable valve provides the functions of a safety valve.
