Abstract
A taper sealing high-pressure check valve for a cleaning machine comprises a plastic valve body mounted in a pump. One end of the plastic valve body is connected with a valve seat, the other end of the plastic valve body is connected with a joint, and a stainless steel spring and a valve core are mounted in the valve body. The taper sealing high-pressure check valve is characterized in that the valve core is a taper inclined plane valve core in contact seal with the valve seat through an inclined plane. According to the scheme, the valve core is made into the taper inclined plane valve core which is conical, the strength of the valve core is improved, the service life of the valve core is long, the contact sealing performance of the inclined plane is more reliable, the check valve can be normally sealed under the action of the stainless steel spring, and the check valve can be opened by overcoming spring force when pressure inside the pump is higher than that outside the pump.
Description
Technical field
The utility model relates to a kind of washing machine tapering sealed high pressure one-way valve, belongs to the washing machine valve components.
Background technique
At present, washing machine is to adopt metal valve body and spool with the high pressure one-way valve mostly, and metal valve body and spool have the advantage of intensity aspect, but have following shortcoming: cost of material is high, and owing to the restriction of valve arrangement, processing difficulties yields poorly simultaneously.Therefore, existing in recent years people more and more adopts engineering plastics to replace metal, and plastics valve body and spool adopt mold injection molding; Reduce material and processing cost; Satisfy batch production requirement, but because plastics intensity is lower than the congenital problem of metal strength all the time, and structurally still adopt the plane contact sealing between spool and the valve seat; Cause the working life of spool short, poor sealing performance.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art, to provide a kind of spool to adopt the sealing of tapering inclined-plane, intensity height, good seal performance, the washing machine tapering sealed high pressure one-way valve of long service life.
The technological scheme of the utility model washing machine tapering sealed high pressure one-way valve is: comprise the plastics valve body that is installed in the pump housing; One end of plastics valve body connects valve seat; The other end jointing of plastics valve body; In the plastics valve body, be equipped with stainless steel spring and spool, it is characterized in that described spool is a tapering inclined-plane spool, tapering inclined-plane spool and valve seat are through inclined-plane contact seal.
The washing machine tapering sealed high pressure one-way valve of the utility model is processed tapering inclined-plane spool with described spool, and is tapered; The intensity of spool is improved; Long service life, and tapering inclined-plane spool and valve seat are through inclined-plane contact seal, inclined-plane contact seal more reliable performance; One-way valve was in sealing state when the effect through stainless steel spring under the normality made normality, when the pump internal pressure is higher than the outside, can make one-way valve be in opening state through overcoming spring force.
The washing machine tapering sealed high pressure one-way valve of the utility model is shaped on step on the described valve seat, is equipped with O-ring seals on the step, and O-ring seals is with sealing contacts with the pump housing, and sealing is better, and step has been arranged, and it is firm that O-ring seals is installed.Described plastics valve body connects valve seat through the interference mode, and is easy to connect, reliable.
Description of drawings
Fig. 1 is the utility model washing machine tapering sealed high pressure one-way valve structures schematic representation.
Embodiment
The utility model relates to a kind of washing machine tapering sealed high pressure one-way valve; As shown in Figure 1, comprise the plastics valve body 1 that is installed in the pump housing 6, an end of plastics valve body 1 connects valve seat 4; The other end jointing 7 of plastics valve body 1; In plastics valve body 1, be equipped with stainless steel spring 2 and spool, it is characterized in that described spool is a tapering inclined-plane spool 3, tapering inclined-plane spool 3 passes through inclined-plane 8 contact seals with valve seat 4.This programme is processed tapering inclined-plane spool 3 with described spool; Tapered, make the intensity of spool improve long service life; And tapering inclined-plane spool 3 passes through inclined-plane 8 contact seals with valve seat 4; Inclined-plane 8 contact seal more reliable performance, one-way valve was in sealing state when the effect through stainless steel spring under the normality made normality, when the pump internal pressure is higher than the outside, can make one-way valve be in opening state through overcoming spring force.Be shaped on step 9 on the described valve seat 4, be equipped with O-ring seals 5 on the step, O-ring seals 5 is with 6 sealings contact with the pump housing, and sealing is better, and step has been arranged, and it is firm that O-ring seals is installed.Described plastics valve body 1 connects valve seat 4 through the interference mode, and is easy to connect, reliable.
