Abstract

The invention relates to a check valve, which comprises a membrane, a membrane pressing ring and a valve seat, wherein the membrane comprises an inner round sheet, an outer ring and a tension bar connected with the inner round sheet and the outer ring; the inner round sheet is used for sealing; the outer ring is fixed on the valve seat through the membrane pressing ring; and the tension bar is elastic, so that the inner round sheet is limited to only move within a certain range, and can be reset. The check valve has the advantages that: activities of the membrane during opening and closing are controlled by the tension bar; the membrane can be relatively thin, so that the inner round sheet of the membrane is well matched with a boss sealing surface of a liquid inlet in the bottom surface of a liquid storage barrel; therefore, the check valve has the advantages of good sealing effect and high reliability.

Description

A kind of one-way valve

Technical field

The present invention relates to a kind of valve, relate in particular to the one-way valve in a kind of vehicle fuel system.

Background technique

At present, the kind of industrial one-way valve is more on the market, with structure of the present invention and the comparatively approaching existing technology of effect mushroom diaphragm one-way valve and dull and stereotyped diaphragm one-way valve is arranged; The structure of wherein dull and stereotyped diaphragm one-way valve comprises diaphragm and diaphragm cover cap, and diaphragm places the diaphragm cover cap, and diaphragm moves up and down in the diaphragm cover cap; Reach the function of opening and closing, this diaphragm is an integrated type, and thickness is thicker; Move up and down and occur the jam phenomenon easily, have that sealing effect is bad, poor reliability gets shortcoming.

Summary of the invention

The objective of the invention is to overcome the deficiency of existing technology, the one-way valve of a kind of sealing effect and good reliability is provided.

To achieve these goals, technical solution of the present invention is such: a kind of one-way valve comprises diaphragm, diaphragm trim ring and valve seat; The lacing wire that described diaphragm is made as interior disk, outer ring and connects interior disk and outer ring; Interior disk is used for sealing, and the outer ring is fixed on the valve seat through the diaphragm trim ring, and lacing wire has elasticity; Disk is only movable in certain scope in the restriction, and disk resets in can making simultaneously.

The invention has the beneficial effects as follows: because the active receiving lacing wire control of diaphragm when opening and closing; It is thinner that the thickness of diaphragm can be done; The interior disk of diaphragm cooperates more docile with the boss sealing surface of stock solution tube bottom surface liquid entering hole, thereby has the advantage of sealing effect and good reliability.

Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is described further:

Shown in Fig. 1~4, a kind of one-way valve of embodiment 1 comprises diaphragm 1, diaphragm trim ring 2 and valve seat 3; The lacing wire 6 that described diaphragm 1 is made as interior disk 4, outer ring 5 and connects interior disk 4 and outer ring 5; Interior disk 4 is used for sealing, and outer ring 5 is fixed on the valve seat 3 through diaphragm trim ring 2, and lacing wire 6 has elasticity; 4 of disks are movable in certain scope in the restriction, and disk 4 resets in can making simultaneously.

Described lacing wire 6 is provided with three that are uniformly distributed with, and every lacing wire is fixedly connected another place that rear curved extends to outer ring 5 from one of interior disk 4 and is fixedly connected with the outer ring.

Described diaphragm 1 is processed for resilient oil resistant plastics or rubber, and preferably fluorine rubber is processed, and described diaphragm trim ring 2 is processed for metal, and preferably stainless steel is processed.

Shown in Fig. 5~8, a kind of one-way valve of embodiment 2, a side end face of described outer ring 5 is laid with several projections 7, is complementary with it, on diaphragm trim ring 2, is provided with several through holes, and outer ring 5 is fixedly connected with diaphragm trim ring 2 through projection 7 card people through holes.All the other structures are identical with embodiment 1, no longer repeat here.

Shown in the scheme of installation of Fig. 3 and 7, one-way valve is anchored in the stock solution tube 8 through diaphragm trim ring 2, and there is the formation sealing surface of a boss and one-way valve diaphragm 1 at the liquid entering hole place of stock solution tube 8 bottom surface valve seats 3; During work; The stock solution tube 8 outside hydraulic couplings of holding are higher than internal hydraulic pressure, thereby open diaphragm 1, and the entering of outside appearance liquid is also filled stock solution tube 8; When inside and outside liquid level pressure reaches balance; Diaphragm 1 resets under the effect of hydrostatic pressure, closes the liquid entering hole of stock solution tube 8 and forms sealing, keeps stock solution tube 8 liquid levels not descend.
