Abstract
The utility model provides a prevent check valve of low air current vibration, when media channel's entrance point has non - target moving gaseouse medium to flow in, this medium can produce an effort to valve clack spare this time, there is the trend of opening valve clack spare, and because add the antivibration subassembly, NOT AND target moving gaseouse medium effort opposite direction's antivibration power is applyed to the antivibration subassembly to valve clack spare, prevent that the valve clack from taking place the vibration, rather than waiting valve clack spare for a long time because of the abrasion part that tries every possible means again to handle after the vibration wearing and tearing, the contacting area who solves valve clack and disk seat from the root decreases because of the vibration goes out freshly ground, the problem of revealing.
Description
Technical field
This utility model is related to a kind of valve, more particularly, it relates to a kind of check-valves of anti-low-flow vibration.
Background technology
The check-valves of common anti-low-flow vibration are generally as shown in figure 1, include valve gap, valve body, valve seat, flap, flap
Lid, valve rod, valve gap is arranged at body top, valve seat be arranged in valve body and conflict during flap closure be connected to meal do both shape
Become sealing, flap is arranged on to be fixed by valve clack cover on rocking bar, and rocking bar is hingedly connected on valve body by valve rod, and valve rod is typically
It is placed in valve body.Entrance point in valve body has fluid media (medium)（As gas medium, liquid medium）The active force flowing into and producing
When sufficiently large, flap is opened, thus realizing flowing transmission from entrance point to the port of export for the fluid media (medium).
There is following drawback in the check-valves of this traditional anti-low-flow vibration：When entrance point has a small amount of non-targeted air-flow
Medium entrance, produces certain active force to flap but this active force is insufficient to allow flap to open again, and now flap will produce
Certain vibration and make a noise, the contact site of flap and valve seat meanwhile, if flap is continually in this state, can be led to
Leakage can be produced because of abrasion.
Those skilled in the art's common practice is exactly to arrange sealing ring in the contact site of flap and valve seat or increase valve
The wearability of this contact site, but these ways all can not at root solve problem, simply extend lead to wear and tear time,
Whole flap and valve seat still can because of being chronically at such a vibration, the environment of friction and occurring leaks.
Utility model content
The purpose of this utility model is to be to provide a kind of check-valves of anti-low-flow vibration, prevents the entrance point of check-valves
There is non-targeted moving gaseouse medium to enter fashionable and lead to flap to vibrate, solve flap at root with the contact site of valve seat because shaking
The problem moved and occur wearing and tearing, revealing.
A kind of check-valves of anti-low-flow vibration, includings valve body and opening/closing component, be provided with described valve body band entrance point with

The structure that the present embodiment and prior art have difference part is as follows：
As shown in Figure 2,3, described valve rod 41 two ends all pass valve body 1 composition force side 411, each force side 411 described
All it is connected and has vibrationproof assembly, when flap part 42 is in closure state and has non-targeted moving gaseouse medium to produce work to flap part 42
When firmly, described vibrationproof assembly passes through force side 411 and flap part 42 is applied with vibrationproof power, and described vibrationproof power is situated between with non-targeted air-flow
Matter force direction is contrary.
Described vibrationproof assembly includes force application component 51, locking member 52 and energy accumulation member 53.
Described force application component 51 is connected and opening with ovable valve stem 41 control flap part 42 with the force side 411 of valve rod 41
Close, described locking member 52 is fixed on valve body 1 and is mutually locked with force application component 51 or be mutually disengaged, described energy accumulation member 53
With force application component 51, stored energy when force is allowed to close is being carried out to opening/closing component, with force application component 51 to opening/closing component
Carry out releasing energy when force is allowed to close.
Described force application component 51 includes the pretension flange 511 being fixedly connected and boosting-rod 512, pretension flange 511 and force
End 411 is fixedly connected.Support 521 that described locking member 52 includes being fixedly connected with valve body 1, it is hinged on by jointed shaft 523
Locating piece 522 on support 521.Described pretension flange 511 is connected with support 521 and is provided with confession towards the side of support 521
The fixing screens groove 5111 of locating piece 522, as shown in figure 4, screens groove 5111 is provided with several and uniformly divides along its circumferencial direction
Cloth.It should be strongly noted that so that locating piece 522 can effectively be fixed to pretension flange 511, will not be because of gravity
Effect and automatically disengage pretension flange 511, therefore the present embodiment is preferably, the jointed shaft 523 of locating piece 522 and valve body 1 perpendicular to
Ground.
Described energy accumulation member 53 includes being set in the torsion spring 531 of force side 411, is respectively fixedly connected with torsion spring 531 two ends
Axle cap 542 and fixture 533, wherein, fixture 533 is pretension flange 511（Need, fixture 533 and pretension herein
Flange 511 can also be different two parts, and now fixture 533 needs to be fixedly connected with pretension flange 511, but considers
To for so from effect, do not increase beneficial effect and instead increased manufacturing cost, so the present embodiment is preferably
Fixture 533 is pretension flange 511）.Between described force side 411 and torsion spring 531, interference fits or interference fit have fixation

Operator exert a force to boosting-rod 512, control pretension flange 511 to rotate, pretension flange 511 carries ovable valve stem 41
Rotate, valve rod 41 rotates and drives flap part 42 closure or openness.In boosting-rod 512,41 turns of ovable valve stem is carried by pretension flange 511
In dynamic process, because the torsion spring 531 on force side 411 is fixedly connected with axle cap 542 with pretension flange 511,
Torsion spring 531 can be in accumulation of energy or the state releasing energy according to the rotation direction of pretension flange 511.When flap body 422 and valve
Seat 3 is when being in closure state, because there being torsion spring 531 to be in energy accumulating state, this when is when having non-targeted moving gaseouse medium from entering
Mouth end 12 enters, when striking flap body 422, because flap body 422 and valve seat 3 are at closure state in itself, this
When torsion spring 531 can automatically to valve rod 41 apply a vibrationproof power contrary with non-targeted moving gaseouse medium active force, effectively prevent
Flap body 422 produces to vibrate or open by mistake and opens；When flap body 422 is in opening with valve seat 3, torsion spring 531 is in
Storage releases energy state, does not interfere the circulation of target fluid medium.
