Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Referring to fig. 1-4, the present invention details the above technical solution by the following embodiments:

the utility model provides a convenient fixed pump valve with change backing layer, two sliding tray 41 including two valve pocket 4 and 4 inner walls of valve pocket, the one end that the pump valve center was kept away from to sliding tray 41 is equipped with rotation groove 42, the inner wall of valve pocket 4 is located to rotation groove 42, the other end that rotates groove 42 is equipped with fixed slot 43, the inner wall of valve pocket 4 is located to fixed slot 43, the other end of fixed slot 43 is equipped with stopper 45, the inside both sides of fixed slot 43 are equipped with two screens piece 44, the bottom of screens piece 44 is equipped with screens piece arrangement groove, the both sides wall of fixed slot 43 is located to screens piece arrangement groove, the first spring of bottom fixedly connected with of screens piece 44, fixed connection between the other end and the screens piece arrangement groove of first spring, fixed connection between stopper 45 and right valve body 2 and the left valve body 3.

What needs to be supplemented is: and a fastening screw 5 is arranged between the right valve body 2 and the left valve body 3, and the right valve body 2 and the left valve body 3 are fixed and detached through the fastening screw 5.

It is worth mentioning that: the screens piece 44 is the triangular cone form, the glossy inclined plane of its both sides face position, its vertebra tip part is outside, and the tip of its awl bottom part then hides inside screens piece arrangement groove, this kind of setting can be realized when the screens piece 44 is touch to fixed block 61, because the existence of inclined plane, can extrude screens piece 44 to screens piece arrangement inslot, and then can be when screens piece 44 and screens groove 63 are just to the time, utilize the automatic card of the elasticity of first spring to go into in screens groove 63, it also can normally take out to arrange fixed block 61, avoided backing layer 6 by the dead condition of screens piece 44 card.

Two fixing blocks 61 on the lining layer 6 are aligned to the positions of the two sliding grooves 41, the lining layer 6 is slid into the sliding grooves 41 through the sliding grooves 41 until the top end, at this time, the arc-shaped connecting block 62 at the front end of the lining layer 6 is contracted under the action of the second spring, then the lining layer 6 is rotated along the rotating groove 42 until the fixing blocks 61 touch the limiting block 45, then under the elastic force of the second spring, the arc-shaped connecting block 62 is extended outwards, and the fixing blocks 61 are clamped into the fixing grooves 43.

The outside fixedly connected with right valve body 2 and left valve body 3 of valve chamber 4, the one end fixedly connected with ring flange 1 at pump valve center is kept away from to right valve body 2 and left valve body 3.

The whole pump valve is separated by the fastening screw 5 into the right valve body 2 and the left valve body 3, thereby facilitating the replacement operation of the lining layer 6.

A lining layer 6 is arranged inside the valve cavity 4, fixing blocks 61 are fixedly connected to the upper end and the lower end of the lining layer 6, two second springs are fixedly connected to the front ends of the fixing blocks 61, arc-shaped connecting blocks 62 are fixedly connected to the other ends of the second springs, clamping grooves 63 are formed in the middles of the left end and the right end of the fixing blocks 61, and the clamping grooves 63 are formed inside the fixing blocks 61.

It is worth mentioning that: arc connecting block 62 is the semi-cylinder type, and the one end and the second spring fixed connection of its rectangle, the other end then are the smooth surface, therefore when backing layer 6 removed in valve chamber 4, reduce the area of contact of arc connecting block 62 and valve chamber 4, reduce frictional force, the removal of backing layer 6 of being convenient for is further simultaneously advanced to the smooth surface.

When the fixing block 61 is clamped into the fixing groove 43, the arc-shaped connecting block 62 extends outwards under the elastic force of the second spring, the arc-shaped connecting block 62 abuts against the flange plate 1 to further fix the lining layer 6, when the fixing block 61 is clamped into the fixing groove 43, the fixing block 61 moves into the fixing groove 43 under the elastic force of the second spring, and meanwhile, the conical tip side of the clamping block 44 is pressed to generate a downward movement force, then, under the help of the first spring, the clamping block 44 retracts into the clamping block containing groove, when the fixing block 61 is completely clamped into the fixing groove 43, the clamping groove 63 moves to the upper end of the clamping block 44, at the moment, the clamping block 44 does not bear the downward movement force any more, extends outwards under the elastic force of the second spring and is clamped into the clamping groove 63, and therefore the stability of the lining layer 6 is further improved.

When the pump valve is used, the whole pump valve is separated by the fastening screw 5, the pump valve is divided into the right valve body 2 and the left valve body 3, then two fixing blocks 61 on the lining layer 6 are aligned to the positions of the two sliding grooves 41, the lining layer 6 slides into the sliding grooves 41 through the sliding grooves 41 until the top end, the arc-shaped connecting block 62 at the front end of the lining layer 6 contracts under the action of the second spring, then the lining layer 6 rotates along the rotating grooves 42 until the fixing block 61 touches the limiting block 45, then the arc-shaped connecting block 62 extends outwards under the elastic force of the second spring, the fixing block 61 is clamped into the fixing groove 43, the arc-shaped connecting block 62 is abutted against the flange 1, when the fixing block 61 is clamped into the fixing groove 43, under the elastic force of the second spring, the fixing block 61 moves into the fixing groove 43 while pressing the conical tip side of the clamping block 44 to generate a downward moving force, then under the help of the first spring, the clamping block 44 retracts into the clamping block into the clamping groove of the clamping block 6, when the fixing block 61 is completely inside the fixing groove 43, the clamping block 44 is pulled out, then the clamping block is pulled out, the clamping block 6 is further pushed into the left valve body 6, the clamping groove, the clamping block 6 is pulled out by the left clamping groove, the clamping block 6, the clamping groove, the clamping block 6 is further pushed downwards under the action of the clamping groove, and the clamping block 6, and the clamping groove, the clamping block 6, the clamping groove, and the clamping block 6, the clamping groove, the clamping block 6 is further pushed out by the clamping block 6, and the clamping groove, and the clamping block 6, and the clamping groove, and the clamping block 6 is pulled out of the clamping groove, and the clamping block 6, the replacement and mounting of the lining layer 6 is then completed.

The foregoing shows and describes the basic principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
