Abstract

The utility model provides a check valve body which comprises a valve body unit, the valve body unit is provided with a check valve plate which is fixedly connected with the valve body unit through a valve body pin shaft, the check valve plate can open or close the valve body unit, and at least two through holes are formed in the surface of the valve plate. The check valve body is simple in structure, convenient to produce, machine and use, and low in manufacturing cost, and is a substitute product of existing valve bodies.

Description

Check valve case

Technical field

The utility model relates to a kind of check valve case.

Background technique

Existing valve body structure is comparatively complicated, makes difficulty, can not meet the needs of production, and is unfavorable for enhancing productivity.

The model utility content

For the existing shortcomings and deficiencies of making, it is a kind of simple in structure that the utility model embodiment provides, and processes valve body easy for installation and non-damageable.Described technological scheme is as follows:

The utility model proposes a kind of check valve case, comprise the valve body body, described valve body body has the check valve plate, and described check valve plate is fixedly connected with the valve body body by the valve body bearing pin, described check valve plate can be closed described valve body body by Da Kai, and described valve plate surface has at least two through holes.

Preferred as technique scheme, described valve body end part of pin shaft adopts seal ring, plain cushion, bullet pad and bolt seals and fixes.

Preferred as technique scheme, described valve plate internal surface is fixedly installed positioning block, and in opened condition the time, described positioning block contacts with the valve body body internal surface, with the angle between maintenance valve plate and valve body body when valve plate.

Preferred as technique scheme, described valve body entry end is provided with cushion pad, and when valve plate was closed, described cushion pad contacted setting with valve plate.

Preferred as technique scheme, the angle ranging from 15 °.

The beneficial effect that the technological scheme that the utility model embodiment provides is brought is: a kind of check valve case that the utility model proposes, not only simple in structure, production, processing, easy to use; And low cost of manufacture, be the substitute products of present valve body.

Description of drawings

In order to be illustrated more clearly in the technological scheme in the utility model embodiment, in below describing embodiment, the accompanying drawing of required use is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is that the valve body master who provides in the present embodiment 1 looks cut away view;

Fig. 2 is the valve body side-looking cut away view that provides in the present embodiment 1;

Fig. 3 is the plan view of Fig. 1.

Embodiment

, for making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model mode of execution is described in further detail.

Embodiment 1

the utility model proposes a kind of check valve case, comprise valve body body 1, as Fig. 1, Fig. 2, shown in Figure 3, described valve body body 1 has check valve plate 3, described check valve plate 3 is fixedly connected with valve body body 1 by valve body bearing pin 2, described valve body bearing pin 2 is for adopting stainless steel, prevented corrosion, stuck, rotate the generation of the phenomenon such as dumb, seal ring is adopted in valve body bearing pin 2 ends, plain cushion 4, bullet pad and bolt 5 seal fixing, described check valve plate upper surface is fixedly installed positioning block, described check valve plate 3 can be closed described valve body body 1 by Da Kai, described check valve plate 3 surfaces have at least two through holes 9.

As shown in Figure 2, described valve plate 3 internal surfaces are fixedly installed positioning block 7, and in opened condition the time, described positioning block 7 contacts with valve body body 1 internal surface when valve plate 3, and to keep the angle between valve plate 3 and valve body body 1, it is good the angle ranging from 15 degree.

Described valve body entry end is provided with cushion pad 6, and when valve plate 3 was closed, described cushion pad 6 contacted setting with valve plate 3.

Shock absorbing power when distortion valve body 1 entry end has distortion valve body cushion pad 6 to close for distortion valve body plate 3., with screw 8 fixed deformation valve body positioning blocks 7, be used for adjusting the size that distortion valve body plate 3 is opened on distortion valve body plate 3, guarantee the flow of valve body.

When being connected with electric pump and starting, due to the impact of current, in opened condition, described positioning block 7 contacts with valve body body 1 internal surface check valve plate 3,, to keep 15 ° of angles between valve plate and valve body body, has guaranteed that the current of current pass through.When shutting down, due to the effect that water hangs down, check valve plate 3 is closed automatically,, because valve body body entry end is provided with rubber buffer, has both alleviated the impact force of valve plate, makes again check valve plate 3 contact and seal with cushion pad 6.There are two flowing holes on the valve plate surface, the water in pipeline can only by flowing hole slowly carry out earial drainage, thereby played the effect of protection electric pump

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
