When the automatically controlled switching valve 51 of two-way is not triggered, switching core body 512 is located at the high pressure gas in extremely upper position, compression gas tank 52
Body, which is sequentially passed through, enters pneumatic operated valve body 1 after the 3rd air inlet 5113, through hole, the first gas outlet 5111, the first air inlet 11, and pushes away
Dynamic main valve stem 4 is moved down, and holding natural gas is normal aeration status；When the automatically controlled switching valve 51 of two-way is triggered, switch core body
512 move down to extremely bottom and put, and the gases at high pressure in compression gas tank 52 sequentially pass through the 4th air inlet 5114, through hole, the second outlet
Enter pneumatic operated valve body 1 after the 5112, second air inlet 12 of mouth, and promote main valve stem 4 to move up, realize the source of the gas of pneumatic valve body 1
Cutting function, it is practical.
In the present embodiment, the Pneumatic assembly 5 also includes main valve linker 53, the first gas outlet 5111 and the second gas outlet
5112 are connected with the first air inlet 11 and the second air inlet 12 respectively by main valve linker 53.Specifically, the 3rd air inlet
The air inlet 5114 of mouth 5113 and the 4th is connected by gas tank linker 54 with compression gas tank 52.In each portion of the present utility model
In the connection procedure of part, connected without using pipeline, not only increase connection tightness and the sealing between all parts
Property, assembly working is simpler quick, reduces difficulty of processing and production cost, cost performance is higher.
In the present embodiment, the resetting-mechanism 23 includes spring 231 and the regulation machine-processed rice being threadedly coupled with from lock housing body 21
232, the two ends of spring 231 are abutted with the inner of self-lock rod 22 and regulation machine-processed rice 232 respectively.Due to fill type natural gas and pipeline
The air pressure of formula natural gas is different, causes safety-valve driving force to be taken when opening and closing different, its self-locking device 2
Locking power also has difference, by rotating regulation machine-processed rice 232, thus it is possible to vary the decrement of spring 231, to realize repairing for self-locking dynamics
Just, it is achieved thereby that adjusting the function of self-locking dynamics for different use environments, applicability is wider.
In the present embodiment, the self-lock rod 22 is fixedly connected with shifting part 24, and the clicking section is extended to from lock housing body 21
Outside, is easy to operating personnel to carry out self-locking releasing action more easily, simple to operate, practical.
