Abstract
This application discloses a kind of valve clack of safety valve, including body, the bottom of this body is recessed is formed with a groove, the sidewall of this groove offers pod apertures, is provided with filter screen in described groove.This flap is defecator at flap envisaged underneath, can filter out impurity in medium while not affecting negotiability to a great extent, protection sealing surface intact, extends the service life of valve.
Description
Technical field
The application relates to a kind of relief valve, particularly relates to a kind of valve clack of safety valve, applies in cryogenic pipe, play anti-
Only the pressure medium in pipeline exceedes setting pressure, the effect of protection pipeline safety..
Background technology
Low-temperature safety valve is applied to and in all kinds of cryogenic pipe, when the cryogenic gas in low-temperature pressure container pipeline is more than one
During fixed rated value, low-temperature safety valve can automatically turn on, and discharges gas, thus reaches the purpose of pressure release, makes pipeline and low temperature hold
Pressure in device remains in safety range, to guarantee that the safety of all kinds of production is carried out.
Relief valve in the market is easy to because the degree of purity of pipeline medium causes sealing property to decline, even not
It is loss of seal performance, causes dielectric leakage, life of valve to be greatly shortened.
Utility model content
The purpose of this utility model is to provide a kind of valve clack of safety valve, to overcome deficiency of the prior art.
For achieving the above object, the following technical scheme of this utility model offer:
The open a kind of valve clack of safety valve of the embodiment of the present application, including body, the bottom of this body is recessed is formed with a groove,
Offer pod apertures on the sidewall of this groove, in described groove, be provided with filter screen.
Preferably, in above-mentioned valve clack of safety valve, described body includes that main part and main body bottom are the most convex
The sealing stretched, described groove is recessed in the end of described sealing.
Preferably, in above-mentioned valve clack of safety valve, the outer sheath of described sealing is provided with sealing ring, the end of this sealing ring
End is positioned at above described pod apertures.
Preferably, in above-mentioned valve clack of safety valve, the bottom of described main part protrudes out downwards the fixed part of annular, should
Fixed part is sheathed on the outside of described sealing, forms a grasping part, described sealing ring between described fixed part and sealing
It is fixed in described grasping part.
Preferably, in above-mentioned valve clack of safety valve, the bottom of described sealing ring protrudes out outside described grasping part.
Preferably, in above-mentioned valve clack of safety valve, the bottom of described fixed part is formed with guide ramp.
Preferably, in above-mentioned valve clack of safety valve, described grasping part shrinks at opening part.
Compared with prior art, the utility model has the advantage of:
This flap is defecator at flap envisaged underneath, can be to a great extent while not affecting negotiability
Filter out impurity in medium, protect the intact of sealing surface, extend the service life of valve.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present application or technical scheme of the prior art, below will be to embodiment or existing
In having technology to describe, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only this
Some embodiments described in application, for those of ordinary skill in the art, on the premise of not paying creative work,
Other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 show the structural representation of valve clack of safety valve in this utility model specific embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Detailed description, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole enforcement
Example.Based on the embodiment in this utility model, those of ordinary skill in the art are institute on the premise of not making creative work
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Shown in Fig. 1, valve clack of safety valve, including body 1, the bottom of this body 1 is recessed is formed with a groove, this groove
Sidewall on offer pod apertures 11, be provided with filter screen 2 in groove.
Further, body 1 includes the sealing 13 that main part 12 and main body 12 bottom protrude out downwards, groove
Recessed in the end of sealing 13.
Further, the outer sheath of sealing 13 is provided with sealing ring 3, and the bottom of this sealing ring 3 is positioned in pod apertures 11
Side.
Further, the bottom of main part 12 protrudes out downwards the fixed part 14 of annular, and this fixed part 14 is sheathed on close
The outside in envelope portion 13, forms a grasping part between fixed part 14 and sealing 13, sealing ring 3 is fixed in grasping part.
Further, grasping part shrinks at opening part.Owing to sealing ring has certain elasticity, clamping can be limited in
In space.
Preferably, the bottom of sealing ring 3 protrudes out outside grasping part.
Preferably, the bottom of fixed part 14 is formed with guide ramp 141.
This flap is defecator at flap envisaged underneath, can be to a great extent while not affecting negotiability
Filter out impurity in medium, protect the intact of sealing surface, extend the service life of valve.
It should be noted that in this article, the relational terms of such as first and second or the like is used merely to a reality
Body or operation separate with another entity or operating space, and deposit between not necessarily requiring or imply these entities or operating
Relation or order in any this reality.And, term " includes ", " comprising " or its any other variant are intended to
Comprising of nonexcludability, so that include that the process of a series of key element, method, article or equipment not only include that those are wanted
Element, but also include other key elements being not expressly set out, or also include for this process, method, article or equipment
Intrinsic key element.In the case of there is no more restriction, statement " including ... " key element limited, it is not excluded that
