Description

Soft seal check valve
Technical field
The utility model is related to a kind of check valve, especially a kind of soft seal for preventing reverse flow of fluids in pipe-line system Check valve.
Background technology
Check valve makes fluid to be flowed along water inlet, and delivery port medium cannot but flow back, check valve also known as check-valves or Non-return valve, is generally used for preventing oil stream reverse flow in hydraulic system, or for preventing compressed air reverse in pneumatic system Flowing.
The key point of check valve is the sealing problem of unidirectional opening ways and valve plate in the prior art.It is single at present It is typically all that sealing is realized by sealing ring to the valve plate of valve.Sealing ring of the prior art is generally divided into:V-shaped seal ring, U Type circle, O-ring seal, square type sealing ring, y-type seal ring etc., its principle are that sealing ring forms linear sealing with valve plate.But actually make Abrasion, or flexibility decrease occur under permanent use with middle discovery sealing ring, so that sealing effectiveness reduction;Now just need Change sealing ring or change whole valve body, influence production.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of soft seal check valve, the list Sealed by the sealing ring of point contact to the valve body of valve, the long service life of sealing ring, good sealing effect.
According to the technical scheme that the utility model is provided, the soft seal check valve, including valve body set valve on valve body Seat, the centrally disposed valve opening of valve seat, the side of valve opening is import, and the opposite side of valve opening is outlet;In the valve seat towards outlet The upper end of side sets mounting groove, and valve plate is set in the outlet side of valve opening, and the top of valve plate sets pivot part, and pivot part is rotated It is arranged on mounting groove;Sealing ring mounting groove is set towards the side of outlet in the valve seat, valve is set in sealing ring mounting groove Plate sealing ring;It is characterized in that:The valve plate sealing ring includes multiple overlapped sealing rings being placed in sealing ring mounting groove, Each sealing ring has multiple raised lug bosses towards the side of valve plate, and lug boss forms multiple points in sealing contact with valve plate.
Further, described each sealing ring is the structure being separated from each other.
Further, the sealing ring is 4.
Further, there are two lug bosses on each sealing ring.
Further, the valve body top is provided with handle.
Further, the both sides end face in the valve body is respectively provided with valve seals.
Soft seal check valve described in the utility model, Multi-point sealing is carried out by a sealing ring for contact, sealing ring Long service life, good sealing effect.
Brief description of the drawings
Fig. 1 is the structural representation of soft seal check valve described in the utility model.
Fig. 2 is the structural representation of the sealing ring.
Specific embodiment
With reference to specific accompanying drawing, the utility model is described in further detail.
As shown in Fig. 1~Fig. 2:The soft seal check valve includes handle 1, valve seals 2, valve body 3, valve seat 4, valve plate 5th, valve opening 6, mounting groove 7, pivot part 8, valve plate sealing ring 9, sealing ring 10, lug boss 11, sealing ring mounting groove 12, import 21, Outlet 22 etc..
As shown in figure 1, soft seal check valve described in the utility model, including valve body 3, the both sides end face of valve body 3 sets respectively Put valve seals 2, the sealing that valve seals 2 are used between valve body 3 and pipe laying;Valve seat is set on the valve body 3 4, the centrally disposed valve opening 6 of valve seat 4, the side of valve opening 6 is import 21, and the opposite side of valve opening 6 is outlet 22;In the valve seat 4 Mounting groove 7 is set towards the upper end of 22 sides of outlet, valve plate 5 is set in the side of outlet 22 of valve opening 6, the top of valve plate 5 is set Pivot part 8, pivot part 8 is rotatably arranged in mounting groove 7;Sealing ring is set in the valve seat 4 towards the side of outlet 22 to install Groove 12, sets valve plate sealing ring 9 in sealing ring mounting groove 12, and valve plate sealing ring 9 is contacted with valve plate 5, to realize the close of valve plate 5 Envelope.
As shown in Fig. 2 the valve plate sealing ring 9 includes 4 overlapped sealings being placed in sealing ring mounting groove 10 Circle 10, each sealing ring 10 has two lug bosses 11 of projection towards the side of valve plate 5, and each sealing ring 10 passes through lug boss 11 Two points in sealing contact are formed with valve plate 5;The utility model can effectively improve sealing effect by the Multi-point sealing to valve plate 5 Really.
4 sealing rings 10 are the design that is separated from each other, when wherein certain or certain several sealing rings are because make to be occur During the problems such as abrasion or flexibility decrease, other sealing rings 10 can still realize good sealing effectiveness, so as to improve The service life of integral sealing ring.
In addition, the top of the valve body 3 is provided with handle 1, to facilitate installation operation.
Operation principle of the present utility model:When fluid is flowed into from import 21, lower valve plate 4 dozens is acted in the pressure of fluid Open, flowed out from outlet 22;When fluid is flowed into from outlet 22, Fluid pressure and valve plate 5 act on valve seat 4, so that flowing is cut off, And good sealing effectiveness is realized by valve plate sealing ring 9.
