Operation principle of the present utility model：
See Fig. 1, under nature, the first valve element 12 of plug travels forward in the presence of the first spring 16, reaches and moves
During dynamic snap ring 14, because the elastic force of second spring 17 is more than the elastic force of the first spring 16, the stop of the first valve element 12, the first spring 16
Effect be make the first valve element 12 overcome frictional force complete reset, the first valve core seal ring 18 deformation seal on the first valve element 12
One the first relief hole 125 of circle, plug keep sealing state；See Fig. 2, when plug inside fluid pressure (pressure) increase, act on
When the elastic force sum of pressure and the first spring 16 on first valve element 12 is more than the elastic force of second spring 17, the mobile quilt of snap ring 14
Promote, along stop after annular groove 19 is moved rearwards certain distance is moved, the first valve core seal ring 18 is by the first seal spool hole 110
Moved to the first sealed ring deformation hole 111, because radial diameter becomes big, radial space becomes big, while the first valve core seal ring 18
Deformation under pressure and, circle first relief hole 125 forward end seal upwardly-deformed at most in the side of extrusion gap maximum
Incessantly, liquid just sprays along the first relief hole 125, and plug inside pressure declines after hydrojet, in the presence of second spring 17, moves
Dynamic snap ring 14 drives the first valve element 12 to retreat, and returns to original state, completes releasing pressure automatically process.
See Fig. 5, under nature, diversion column is withstood in the rear end of diversion column 23 in the presence of the spring force of the 3rd spring 25
Snap ring 24, positioned by diversion column snap ring 24, the front end of diversion column 23 positions by the boss of the second valve element 22, close in the second valve element
Seal 26 deforms second relief hole 234 of circle sealed on diversion column, and socket keeps sealing state；Part Fig. 6, the liquid inside socket
Body pressure (pressure) increases, and when the pressure acted on diversion column 23 is more than the precompression of the 3rd spring 25, diversion column 23 is pushed away
Dynamic, stop after moving forward certain distance along diversion column moving hole 28, the second valve element inner seal ring 26 is by the second valve element interior sealing
Hole 212 is moved to the second sealed ring deformation hole 211, and because radial diameter becomes big, radial space becomes big while close in the second valve element
Seal 26 deforms under pressure and the side maximum in extrusion gap is upwardly-deformed at most, second relief hole 234 of circle
Back-end sealing does not live, and liquid just sprays along the second relief hole 234, and internal pressure declines after hydrojet, in the work of the 3rd spring force 25
Under, diversion column 23 retreats, and returns to original state, completes releasing pressure automatically process.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
