ス遮断弁。 The primary side (inflow side) and the secondary side (
a flow chamber that communicates with the flow chamber (outflow side), a valve body operated by a valve operating mechanism provided opposite to the valve nozzle of the flow chamber, and a primary side gas pressure drop that communicates with the primary side. It consists of a detection mechanism and a secondary side gas leak detection mechanism that communicates with the primary side and the secondary side, and the primary side gas pressure drop detection mechanism and the secondary side gas leak detection mechanism are divided into three rooms within the housing. to divide the two diaphragms, i.e.
A diaphragm for detecting a drop in primary gas pressure and a diaphragm for detecting a secondary gas leak are arranged at intervals, and an atmospheric pressure receiving chamber communicating with atmospheric pressure is placed outside the diaphragm for detecting a drop in primary gas pressure. Between the pressure drop detection diaphragm and the secondary side gas leakage detection diaphragm, there is a primary side pressure receiving chamber that communicates with the primary side of the distribution chamber via a connecting pipe, and a primary side pressure receiving chamber is connected to the outside of the secondary side gas leakage detection diaphragm. The gas cutoff valve is characterized in that a secondary side pressure receiving chamber is formed which communicates with the secondary side of the above-mentioned circulation chamber via a connecting pipe.
