container valve

Abstract

It is an object of the present invention to provide a container valve capable of reliably switching between sealing and discharging of fluid, and preventing the generation of a fluid conduction sound when discharging the fluid. In the container valve 1 in which the residual pressure maintaining valve mechanism part 100 is installed in the residual pressure maintaining valve mechanism insertion space 404 in which the flow path 60 is formed, the residual pressure maintaining valve mechanism part 100 includes: a front convex part 127, and the front convex part 127 The valve body 120 is provided at the front end of the valve body 120, and the valve body 120 is disposed in the residual pressure holding valve mechanism insertion space 404 so as to move forward and backward freely between the valve closing position and the valve opening position, and the valve body 120 passes through the flow path 60 of the gas G. The pressure retreats toward the valve opening position; the coil spring 160 biases the valve body 120 in the forward direction from the valve opening position toward the valve closing position; the sealing seat 110 and the extrusion part 135, the sealing seat 110 and the extrusion The pressing portion 135 exposes the abutment allowing portion 151 that allows the front convex portion 127 to abut, holds the O-ring 150 , and fixes the seal seat 110 and the pressing portion 135 to the outlet 40 .

Description

Technical field [0001] The present invention relates to a container valve. For example, it relates to a container valve capable of remaining a predetermined pressure of gas in a storage container and having a conduction direction restricting valve mechanism such as a residual pressure maintaining valve mechanism. Background technique [0002] In a valve device that includes an on-off valve that can switch between an open state and a sealed state while conducting fluid such as gas, a conduction direction restricting valve mechanism is generally provided. The conduction direction restricting valve mechanism can A gas with a predetermined pressure remains in the storage container, and the conduction direction restricting valve mechanism is such as a residual pressure maintaining valve mechanism, etc., and different from the on-off valve, the conduction direction restricting valve mechanism restricts the conduction direction of the conducting fluid ( Refer to Patent Document 1).

AI Technical Summary

Problems solved by technology

[0004] However, due to the diversification and use of conventional container valves in various environments, it is necessary not only to discharge fluid reliably, but also to solve the conduction sound caused by the conduction of fluid that has not been a problem in the past.
