Abstract
The utility model discloses a kind of explosion-proof pump air slide valves, it includes valve body, valve deck, eardrum, holds down assembly, the internal cavity of the valve body and valve deck is divided into upper cavity and lower chamber by the eardrum, described hold down assembly is installed on eardrum center, the edge of the eardrum is clamped on valve body and valve deck Mosaic face, part between the center and edge of eardrum is acting section, and there are two the eardrums and stacks setting, and the acting section of two eardrums is identical.Dual eardrum structure can not only improve the service life of eardrum and still ensure that the normal work of distributing valve in the case where there is any one eardrum impaired.
Description
Technical field
The utility model is related to a kind of explosion-proof pump air slide valves.
Background technology
Air slide valve is mostly made of valve body, valve deck, eardrum, and during the continuous air inlet of valve chamber and deflation, eardrum exists
It is easily damaged after continuous dilatation, it is often necessary to replace.
Invention content
The purpose of this utility model is to provide a kind of service life length and more resistant explosion-proof pump air slide valve.
In order to achieve the above objectives, the technical solution adopted in the utility model is：A kind of explosion-proof pump air slide valve comprising
Valve body, eardrum, holds down assembly at valve deck, and the internal cavity of the valve body and valve deck is divided into upper cavity and lower chamber by the eardrum,
Described hold down assembly is installed on eardrum center, and the edge of the eardrum is clamped on valve body and valve deck Mosaic face, eardrum
Part between center and edge is acting section, and there are two the eardrums and stacks setting, the effect of two eardrums
Duan Xiangtong.
Another preferred embodiment is：Abrasionproof bonding sheet is additionally provided between the eardrum.
Another preferred embodiment is：Section trapezoidal shape of the acting section in the plane by eardrum axis.
Since above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：Dual eardrum knot
Structure can not only improve the service life of eardrum and still ensure that the normal of distributing valve in the case where there is any one eardrum impaired
Work.
Description of the drawings
Attached drawing 1 is the structural schematic diagram of explosion-proof pump air slide valve.
Specific implementation mode
As shown in Figure 1, explosion-proof pump air slide valve includes valve body 1, valve deck 2, eardrum 3, holds down assembly 4, the eardrum 3 will
The internal cavity of the valve body 1 and valve deck 2 is divided into upper cavity 5 and lower chamber 6, and described hold down assembly is installed on 3 centre bit of eardrum
It sets, the edge of the eardrum 3 is clamped on 2 Mosaic face of valve body 1 and valve deck, the part between the center and edge of eardrum 3
For acting section 7, there are two the eardrums 3 and stacks setting, and the acting section 7 of two eardrums 3 is identical.Between the eardrum 3
It is additionally provided with abrasionproof bonding sheet 8, abrasionproof bonding sheet 8 is made using wear-resistant material and is formed with adhesive layer on surface, ensure that eardrum 3
Synchronous effect, be effectively prevented eardrum 3 abrasion.Section of the acting section 7 in the plane by 3 axis of eardrum is trapezoidal
Shape.Valve body 1 is fixedly connected with valve deck 2 by 9 phase of bolt assembly.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
