Abstract
The utility model discloses a valve film, comprising a support, wherein the lower surface of the support is sunken inwards, and the support is in a circular plate shape; a film sheet is fixed on the lower surface of the support, the edge part of the support is fixedly connected with the edge part of the film sheet, the support is a rigid component, and the film is an elastic component; a hole is formed in the center of the support, a protruded semispherical surface is arranged at the center of the film sheet, and the top of the semispherical surface is aligned to the hole; the edge part of the support is provided with a mounting hole. According to the valve film, a double-layer structure of combining the rigid component and the elastic component is utilized, so that the sealing effect is good, the sealing pressure is high, and the energy saving effect is good.
Description
Technical field
The utility model relates to a kind of valve part, relates in particular to a kind of valve film.
Background technique
At present, the switch position of valve is generally all provided with valve seat, spool, and the position of spool and valve base sealing is all provided with valve film or other Sealing.
Valve film of the prior art is all single layer structure or overall structure, and sealing effect is poor, sealing load is low.
Summary of the invention
The purpose of this utility model is to provide that a kind of good sealing effect, sealing load are high, the valve film of good energy-conserving effect.
The purpose of this utility model is achieved through the following technical solutions:
Valve film of the present utility model, comprises inwardly recessed discoid support of lower surface, and the lower surface of described support is fixed with diaphragm, and the edge of described support is fixedly connected with the edge of described diaphragm, and described support is rigid pipe, and described diaphragm is elastic component.
The technological scheme being provided by above-mentioned the utility model can be found out, the valve film that the utility model embodiment provides, and due to the double layer construction that adopts rigid pipe to be combined with elastic component, good sealing effect, sealing load are high, good energy-conserving effect.
Accompanying drawing explanation
The sectional structure schematic diagram of the valve film that Fig. 1 provides for the utility model embodiment;
The plane structure schematic diagram of the valve film that Fig. 2 provides for the utility model embodiment.
In figure: 1, support, 2, diaphragm, 3, mounting hole.
Embodiment
To be described in further detail the utility model embodiment below.
Valve film of the present utility model, preferably embodiment is as shown in Figure 1 and Figure 2 for it:
Comprise inwardly recessed discoid support of lower surface, the lower surface of described support is fixed with diaphragm, and the edge of described support is fixedly connected with the edge of described diaphragm, and described support is rigid pipe, and described diaphragm is elastic component.
The middle part of described support is provided with hole, and the middle part of described diaphragm is provided with protruding hemisphere face, and described hemispherical top is over against described hole.
The position of the surrounding in the upper surface hole of described support raises up.
The edge of described support is provided with mounting hole.
The valve film that the utility model embodiment provides, due to the double layer construction that adopts rigid pipe to be combined with elastic component, good sealing effect, sealing load are high, good energy-conserving effect.
The above; it is only preferably embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
