Abstract

The utility model discloses a reposition of redundant personnel relief pressure valve, including disk seat, valve cap, push rod, regulating part, diaphragm, spring, case, valve pocket, decompression passageway and sealing washer, disk seat and valve cap pass through bolted connection, the valve cap middle part is provided with the push rod, threaded connection has the regulating part on the push rod, is equipped with the diaphragm in the valve cap, is equipped with the spring between regulating part and the diaphragm, the diaphragm is connected with the case upper end, the case passes the disk seat, the case lower extreme is established in the valve pocket, is equipped with many the passageways that reduce pressure in the valve pocket, the case passes the decompression passageway in proper order. Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a many decompression passageways in the valve pocket play the effect of certain buffering, prevent the grow of impact and atress, still through the push rod can be convenient the pressure value of regulating spring mechanism and case, effectual improvement security performance, anticorrosive wearing layer on the case improves the life of relief pressure valve, simple structure, and convenient to use is favorable to the marketing.

Description

A kind of shunting decompression valve
Technical field
The utility model relates to a kind of valve, specifically a kind of shunting decompression valve.
Background technique
Reduction valve is the parts by regulating on reduction valve, regulates loine pressure, and relies on the energy of medium itself, make the valve that outlet pressure keeps stable automatically.From hydromechanical viewpoint, reduction valve is the throttle element that a local resistance can change, and namely by changing orifice size, the kinetic energy of flow velocity and fluid being changed, causes the different pressure losses, thus reach the object of decompression.Then rely on the adjustment of control and regulation system, the fluctuation of downstream pressure and spring force are balanced each other, makes downstream pressure keep constant in certain margin of error.Due to excessive, often impact also comparatively large, unbalance stress, cause reduction valve destructible, thus Safety performance is also poor.
Model utility content
The purpose of this utility model is to provide a kind of shunting decompression valve, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
A kind of shunting decompression valve, comprise valve seat, bonnet, push rod, adjusting element, diaphragm, spring, spool, valve pocket, relief passage and seal ring, described valve seat and bonnet are bolted, push rod is provided with in the middle part of bonnet, push rod has been threaded adjusting element, push rod is through adjusting element, diaphragm is provided with in bonnet, spring is provided with between adjusting element and diaphragm, diaphragm is connected with spool upper end, spool is through valve seat, import is provided with in valve seat, outlet, valve pocket, import, valve pocket, outlet is communicated with successively, spool lower end is located in valve pocket, many relief passages are provided with in valve pocket, spool is successively through relief passage.
As further program of the utility model: described adjusting element has and to protrude downwards and in circular positioning part, the upper end of spring is set on the positioning part of adjusting element.
As the utility model further scheme: be provided with seal ring between described spool and valve pocket.
As the utility model further scheme: described spool is coated with one deck anticorrosion antiwear layer.
Compared with prior art, the beneficial effects of the utility model are: the utility model plays the effect of certain buffering by many relief passages in valve pocket, prevent from impacting and stressed change large; Also can the pressure value of Regulation spring mechanism and spool easily by push rod, effectively improve Safety performance; Anticorrosion antiwear layer on spool, improves the working life of reduction valve, and structure is simple, easy to use, is conducive to marketing.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of shunting decompression valve.
Embodiment
Be described in more detail below in conjunction with the technological scheme of embodiment to this patent.
Refer to Fig. 1, a kind of shunting decompression valve, comprises valve seat 1, bonnet 2, push rod 3, adjusting element 4, diaphragm 5, spring 6, spool 7, valve pocket 10, relief passage 11 and seal ring 12, described valve seat 1 is bolted with bonnet 2, push rod 3 is provided with in the middle part of bonnet 2, push rod 3 has been threaded adjusting element 4, push rod 3 is through adjusting element 4, be provided with diaphragm 5 in bonnet 2, between adjusting element 4 and diaphragm 5, be provided with spring 6, adjusting element 4 has and to protrude downwards and in circular positioning part, the upper end of spring 6 is set on the positioning part of adjusting element 4, avoid the wearing and tearing of screw thread on spring 6 pairs of push rods 3, make this structure of relief pressure valve comparatively stable, diaphragm 5 is connected with spool 7 upper end, described spool 7 is coated with one deck anticorrosion antiwear layer, improve the working life of reduction valve, spool 7, through valve seat 1, is provided with import 8 in valve seat 1, outlet 9, valve pocket 10, import 8, valve pocket 10, outlet 9 is communicated with successively, and spool 7 lower end is located in valve pocket 10, is provided with seal ring 12 between spool 7 and valve pocket 10, is provided with many relief passages 11 in valve pocket 10, and spool 7 is successively through relief passage 11.
Working principle of the present utility model is: during utility model works, is played the effect of certain buffering by many relief passages in valve pocket, prevent from impacting and stressed change large; Also can the pressure value of Regulation spring mechanism and spool easily by push rod, effectively improve Safety performance; Be a kind of rational in infrastructure, improve the reduction valve of Safety performance.
