Preferably, the pressure samples mouth for installing pressure gauge is provided on valve body.
It preferably, is Copper alloy material.
In conclusion by adopting the above-described technical solution, compared with the prior art, the beneficial effects of the utility model
Be: container value design works as piston component by the atmospheric pressure compensated equipment being made of atmospheric pressure compensating hole and matched valve seat and spool
When slowly leakage occurs in top cavity, have the effect of that cavity and container pressure balance above compensation to piston component.Finally, living
Plug assembly is maintained in the intracorporal position of valve, and container value is made to have better seal performance to the container for being packaged with extinguishing chemical.
The present embodiment utilizes differential principle, is sealed storage extinguishing medium by itself gas, novel, compact structure, light,
Sealed reliable.
