Embodiment Construction
[0024] Such as Figure 1 to Figure 5 As shown, an embodiment of a gas cylinder valve is shown. The gas cylinder valve in this embodiment includes a valve body 1. The valve body 1 has left and right openings. The left end of the valve body 1 is the bottle connecting end and the right end for connecting the gas cylinder. For the valve port end used for mating with the corresponding solenoid valve, the valve body has a valve cavity communicating with the left and right ends of the valve body. The valve cavity is provided with a valve seat 101. The valve seat 101 divides the inner cavity of the valve body into separate The left cavity 103 and the right cavity 104 which are arranged on the left and right sides of the valve seat and communicate with each other through the valve seat perforation 105 on the valve seat 101. The valve port filter 2 is installed in the right cavity 104 to move along the left and right directions. 2 Through the inner sealing ring 15 and the valve body 1 in...

The invention relates to a valve seat and a cylinder valve using the same. The cylinder valve comprises a valve body. The valve seat is arranged in a valve cavity of the valve body. A valve element and a reset spring are further arranged in the valve cavity. The valve seat comprises a valve seat body, a valve seat penetrating hole extending in the left-right direction is formed in the valve seat body, one end of the valve seat penetrating hole is a sealing end facing the valve element, and the sealing end of the valve seat penetrating hole is provided with a valve seat sealing ring in seal fit with the valve element. The valve seat sealing ring is fixed to the valve seat body through a fixing sleeve penetrating through the valve seat penetrating hole. The end, corresponding to the sealing end of the valve seat penetrating hole, of the fixing sleeve is fixedly provided with an ejection plate in ejection fit with the valve seat sealing ring, and the other end of the fixing sleeve is integrally provided with a fixing outwards turning edge which turns outwards to be in stop fit with a stop surface where an orifice of the corresponding end of the valve seat penetrating hole is located. The method that the fixing sleeve is fixed to the valve seat body through the fixing outwards turning edge arranged at one end of the fixing sleeve is better in fixing effect, and the sealing ring is convenient to assemble and fix.
Description
Technical field [0001] The invention relates to a valve seat and a gas cylinder valve using the valve seat. Background technique [0002] Cylinder valve is an important component of high-pressure gas cylinder deflation control. It is used on various types of launcher cylinders at home and abroad, and the working pressure is high. At present, most of the gas cylinder valves used on the gas cylinders of the launcher are imported products. The product purchase cycle is long and the price is high. The cost is relatively high from the perspective of use and economic. [0003] A Chinese invention patent with the authorized announcement number CN102032441B discloses a gas cylinder valve, which includes a valve body with upper and lower ends open. The two openings are connected to form a gas flow pipeline. The upper end is the valve port end and the lower end is used for communicating gas. The connecting end of the bottle is fitted with a guide sleeve sliding along the extension direction...
