In above structure, manual ball valve 7 mainly plays maintenance, filter 6 natural air-air source 1 is filtered purify with
Upstream device is protected, pneumatic ball valve 4 realizes that automation control opens and closes action, and the first pressure regulator valve 8 adjusts natural air-air source 1
Pressure, air accumulator 3 play gas storage and pressure stabilization function, and air source bigeminy part 10 plays secondary pressure regulation and catharsis, and solenoid valve 9 plays control action
And it is explosion-proof type.
In the present embodiment, it is additionally provided between the manual ball valve 7 and filter 6 and the second of pressure regulation is carried out to natural air-air source 1
Pressure regulator valve 11.
In above structure, the setting of the second pressure regulator valve 11 can be adjusted at the first time from the natural gas by manual ball valve 7
Air pressure, with protect natural gas next will by equipment.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and modification can also be made, above-mentioned hypothesis these
Improvement and modification also should be regarded as protection scope of the present invention.
