Abstract
The utility model discloses a planar threaded multi-head corrugated metal spring diaphragm, which comprises a body (1). The body (1) comprises a corrugated metal planar spring diaphragm. A small hole (2) is arranged in the center of the body (1), the corrugations are Archimedean spirals, and the body has a multiplayer structure. The planar threaded multi-head corrugated metal spring diaphragm has the benefits of low cost, no need of maintenance and replacement, no leakage and long service life.
Description
Technical field
The utility model relates to a kind of barrier film of membrane valve, particularly a kind of flat thread bull corrugated metal spring barrier film.
Background technique
The diaphragm of existing membrane valve can't replace with metallic material because the institute of structure shape limit, and the while, his working stroke was big too, no matter use what material, this diaphragm is easy to fatigue, causes metallographic structure destruction, the working life of shortening diaphragm.
Summary of the invention
At the defective of the barrier film of present membrane valve, the utility model provides a kind of flat thread bull corrugated metal spring barrier film.To achieve these goals, technical solution adopted in the utility model is:
A kind of flat thread bull corrugated metal spring barrier film comprises body, and body is made of the metal flat spring diaphragm of fold, and the centre of body is provided with aperture;
Described fold is an Archimedes spiral;
Body is a multi-layer structure;
The material of body is a stainless steel.
The beneficial effect of model utility: with low cost, need not maintain and replace, there is not leakage forever, long service life.
Description of drawings
Fig. 1, plan view of the present utility model;
Fig. 2, sectional view of the present utility model.
Embodiment
A kind of flat thread bull corrugated metal spring barrier film comprises body 1, and body 1 is made of the metal flat spring diaphragm of fold, and the centre of body 1 is provided with aperture 2; Described fold is an Archimedes spiral; Body 1 is a multi-layer structure; The material of body 1 is a stainless steel.The beneficial effect of model utility: with low cost, need not maintain and replace, there is not leakage forever, long service life.
Simple replacement of those skilled in the art and replacing all are within this patent protection domain in related domain.
