By adopting technique scheme, positioning rod, spring, ejector rod and movable valve rod are successively set in valve road, valve rod of the prior art be divide into ejector rod and movable valve rod two parts, two parts are compared with valve rod of the prior art, shorten length, make manufacture more simple, increase margin of error, decrease reject rate, solve valve rod in prior art and manufacture difficult and that cost is high problem, the front end of movable valve rod is provided with circular cone simultaneously, circular cone can well seal with inlet hole, when overpressure, movable valve rod is pressed toward elastic component direction, inlet hole realizes being communicated with portalling, when pressure release completes, movable valve rod resets again by elastic component, mounting base is also provided with locating cover, when elastic strength after elastic component Long-Time Service is deteriorated, now by locating cover, positioning rod can be moved in mounting base, increase the elastic potential energy of elastic component to a certain extent, extend service life, need not often change.
Of the present utility modelly to be set to further: described mounting base is provided with through mounting hole, described positioning rod, spring, ejector rod and movable valve rod are all suitable with mounting hole, described mounting base is threaded with locating cover, and described positioning rod abuts with locating cover.
By adopting technique scheme, locating cover is threaded with mounting base, make when rotating position lid, the position of locating cover changes on mounting base, when locating cover rotates toward valve body direction, move toward valve body direction with the conflict positioning rod that is connected of locating cover, positioning rod is by spring compression simultaneously, increase the elastic strength of elastic component, postpone its service life.
Of the present utility modelly to be set to further: described mounting base two ends are equipped with outside thread, and described mounting base is provided with fastening piece relative on one end of locating cover.
By adopting technique scheme, when having been adjusted the position of positioning rod by locating cover, tightened by the direction of fastening piece toward locating cover, because screw thread is obliquely installed, locating cover is contrary with fastener rotation direction, both tighten stuck at realization, and thus locating cover is difficult to rotation occurs, and guarantee that automatic decompression valve structural strength is stablized.
Of the present utility modelly to be set to further: described mounting base is connected with valve body screw thread.
By adopt technique scheme, mounting base is connected with valve body screw thread make both install more convenient, while also convenient for maintaining dismantle.
Of the present utility modelly to be set to further: described positioning rod and ejector rod are equipped with the positioning block be located on spring.
By adopting technique scheme, the positioning block that positioning rod and ejector rod are provided with, make installation more convenient, spring not easily rocks simultaneously.
Of the present utility modelly to be set to further: between described ejector rod and mounting hole, be provided with seal ring.
By adopt technique scheme, seal ring be arranged so that liquid or gas can not enter into spring and positioning rod place or cause leakage, the setting of seal ring is in order to better sealing.
The utility model has following advantage: valve rod of the prior art is divided into ejector rod and movable valve rod, makes production more simple and convenient, reduces cost of production, and the setting of locating cover simultaneously extends the service life of spring.
