Abstract
The utility model discloses a kind of novel elastic check-valves, including：Valve body, valve plate, outer spring, ball, block and inner spring, include in the valve body into water cavity and water chamber, the outer spring is connected on the right side of valve plate between the left side of water chamber, institute's valve plate is circle, its middle part is provided with through hole, the ball is fixed on the left of baffle plate, and inner spring is connected between the left side of delivery port on the right side of baffle plate.Caused by the utility model can avoid ball under excessive impact the problem of serious wear, extend its service life.
Description
Technical field
The utility model is related to field of check valves, specifically a kind of novel elastic check-valves.
Background technology
Check-valves refers to flow in itself by medium and automatic open and close flap, for preventing the valve of medium refluence, also known as
Non-return valve, check valve, reflux valve and counterbalance valve.Check-valves belongs to a kind of automatic valve, and its main function is to prevent medium from falling
Flow, prevent pump and drive motor from inverting, and vessel media is released.Elastomeric check valve refers to make check-valves using elastic force
A kind of check-valves of valve plate closure, it is also the class being most widely used in check-valves.
In a kind of elastomeric check valve structure that Chinese Patent Application No. is 201320847849.3, rubber seal ball is utilized
Elastic packing is realized in indentation sealing circle, is resetted during reset using spring force, integral, flexible sealing can strengthen stopping for check-valves
Effect is returned, the service life of check-valves is extended, the drawbacks of seal form so set has one substantially open in valve plate
Qi Shi, rubber seal ball is directly under pressure the impact of medium, is easy to when surge is excessive by the impurity mill in medium
Damage, so as to reduce its sealing property, therefore service life also have a greatly reduced quality.
Utility model content
The purpose of this utility model is to provide a kind of novel elastic check-valves, to solve what is proposed in above-mentioned background technology
Problem.
To achieve the above object, the utility model provides following technical scheme：
A kind of novel elastic check-valves, including：Valve body, valve plate, outer spring, ball, block and inner spring, the valve
Include in vivo into water cavity and water chamber, the outer spring is connected on the right side of valve plate between the left side of water chamber, and institute's valve plate is
Circle, its middle part is provided with through hole, and the ball is fixed on the left of baffle plate, is connected on the right side of baffle plate between the left side of delivery port
Inner spring.
It is used as further program of the utility model：The modulus of elasticity of the outer spring is less than the modulus of elasticity of inner spring.
It is used as further program of the utility model：The diameter of the through hole is less than the diameter of ball.
It is used as further program of the utility model：The left side of the valve plate sets in annular groove, the annular groove and set
Put sealing ring.
Compared with prior art, the beneficial effects of the utility model are：The utility model is improved to prior art, is led to
The linkage for crossing ball and valve plate is acted on, when pressure is excessive, and valve plate can undertake the current of a part, so as to reduce ball institute
It is stressed, it is to avoid ball the problem of caused serious wear, extends its service life under excessive impact.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, in the utility model embodiment, a kind of novel elastic check-valves, including：Valve body 1, valve plate 2, outer bullet
Include in spring 5, ball 6, block 7 and inner spring 8, the valve body 1 into water cavity 3 and water chamber 9, the outer spring 5 is connected
Between the right side of valve plate 1 and the left side of water chamber 9, institute's valve plate 1 is circle, and its middle part is provided with through hole 21, and the ball 6 is consolidated
The left side of baffle plate 7 is scheduled on, inner spring 8 is connected between the right side of baffle plate 7 and the left side of delivery port 9, in check-valves one-way flow, pressure
Power water is flowed in water chamber 9 by the through hole 21 at the middle part of valve plate 2, and now inner spring 8 is in compressive state, when water flow pressure increases
Greatly, so that when making inner spring 8 in complete compressive state, valve plate 2 will be moved right by flow action, make outer spring
5 are compressed, so, and a part of current just by being flowed through between valve plate 2 and the end face of water inlet 3, alleviate the water of ball 6
Stream, reduces the pressure suffered by it, therefore prevents from water flow pressure excessive to a certain extent causing the direct impact of ball 6
Heavy wear, and in non-return, ball 6 props up the edge of through hole 21, and valve plate 2 props up the right side into water cavity 3, will be only
Return valve sealing.
The modulus of elasticity of the outer spring 5 is less than the modulus of elasticity of inner spring 8, so that valve plate 2 can be in less current
It can also be opened during pressure, alleviate the pressure of ball 6 as early as possible.
The diameter of the through hole 21 is less than the diameter of ball 6.
The left side of the valve plate 2, which is set, sets sealing ring 4 in annular groove, the annular groove, improve the sealing of valve plate 2
Property.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation
Involved claim.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
It may be appreciated other embodiment.
