Description

A kind of NEW TYPE OF COMPOSITE diaphragm
Technical field
This utility model relates to diaphragm technical field, be specifically related to a kind of for fluid pressure type dosing pump, every The NEW TYPE OF COMPOSITE diaphragm of membrane pump, diaphragm valve etc..
Background technology
Membrane pump, as the one of positive displacement reciprocating pump, relies on diaphragm motion, makes seal operation space hold Long-pending generation cyclically-varying, to transmit energy, therefore the quality of diaphragm directly affects the work efficiency of membrane pump And service life.But, existing General Purpose Rubber diaphragm have easily tear, the most wear-resisting, be weak to burn into The shortcomings such as the life-span is short.
Utility model content
For the deficiencies in the prior art, this utility model provides a kind of NEW TYPE OF COMPOSITE diaphragm.
Technical solutions of the utility model are as follows:
A kind of NEW TYPE OF COMPOSITE diaphragm, including the diaphragm body of structure in disk form, described diaphragm body has Four-layer structure, is the first rubber layer, carcass, the second rubber layer and coating layer the most successively, institute State the first rubber layer and the second rubber layer is all by nitrile rubber NBR, ethylene propylene diene rubber EPDM, fluorine rubber Glue VITON or sea uncle's dragon CSM one therein are made, and described coating layer is by polytetrafluoroethylene PTFE system Become, from diaphragm body central from the inside to the outside, be made up of central mounting portion, pushing part, sealing successively, Described central mounting portion and sealing planar structure the most ringwise, the circle centre position of described central mounting portion is provided with Installing through hole, described sealing is provided with the installation fixing hole being distributed ringwise, up and down the two of described sealing Side is all provided with concentric circular seal reinforcement, the most convex groove-like structure in described pushing part, is the first rubber Layer protrudes to coating layer, and is all provided with arc reinforcement spaced apart in it on lateral surface, described in feel at ease It is provided with curved transition sections between dress portion and pushing part.
The thickness range of described diaphragm body is 2.0-10.0mm.
The beneficial effects of the utility model are:
Employing cord fabric is as the skeleton of diaphragm, and makes rubber fully be stained with conjunction sulfuration with cord fabric in sulfidation, Utilize the longitude and latitude structure of cord fabric itself, be greatly enhanced this diaphragm tension stress ability so that it is structure is the most steady Fixed, thus substantially prolongs the service life of this diaphragm;
PTFE is utilized to have excellent chemical stability, corrosion resistance, sealing, high lubrication non-stick, electric insulation Property and good aging resistance endurance, in combination with the soft flexible of rubber, improve General Purpose Rubber diaphragm many Plant performance so that this diaphragm has pressure, wear-resisting, high temperature resistant, acid and alkali-resistance organic solvent burn into anti-tensile The excellent properties such as power is strong, structural stability is strong, thoroughly solve General Purpose Rubber diaphragm easily tear, the most wear-resisting, It is weak to the shortcomings such as the burn into life-span is short, great promotion and use value;
The design of sealing both sides sealing reinforcement, is effectively increased the sealing property of diaphragm sealing surface, it is to avoid because of The leakage problems that poor sealing causes;
The design of outer arcuate reinforcement in pushing part, is effectively increased pull resistance and the intensity of diaphragm.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
