The center of septum body offers mounting hole, and the periphery of septum body offers multiple mounting holes, is located at installation in septum body
There is the protrusion of annular between hole and mounting hole and close to the position of mounting hole.But after protrusion is added to, due to every
Film often the phenomenon that generation diaphragm rupture, in turn results in the breakage of diaphragm when doing reciprocating swing, so that
The service life of entire diaphragm substantially reduces.
Therefore it is simple in structure to be badly in need of one kind, it not only can be on the basis of the flexibility for ensureing single diaphragm activity, moreover it is possible to
Service life is relatively low when overcoming single diaphragm reciprocating movement, and bending place is easier to the pneumatic diaphragm pump diaphragm of phenomenon of rupture.
Invention content
It is simple in structure the object of the present invention is to provide a kind of pneumatic diaphragm pump diaphragm, not only can ensure it is single every
On the basis of the flexibility of diaphragm activity, moreover it is possible to which service life is relatively low when overcoming single diaphragm reciprocating movement, and bending place is more easily broken
Split phenomenon.
The present invention provides following technical solutions：
A kind of pneumatic diaphragm pump diaphragm, including discoidal diaphragm ontology, diaphragm ontology from center to outer edge successively
Including cyclic annular mounting portion, toroidal bend portion and cyclic annular fixed part, the center of mounting portion is equipped with a mounting hole, the outside of fixed part
Edge is equipped with several mounting holes being arranged circumferentially, and bending section includes two that two sides outer peripheral with mounting portion respectively are tightly connected
A first connecting portion connects respectively with two second connecting portions of two sides of fixed part inward flange sealed connection and with first
Two the first curved portions that socket part and second connecting portion integration are connected, the bending direction of two the first curved portions is identical, and the
At least one second curved portion is equipped in one curved portion, the first curved portion is opposite with the bending direction of the second curved portion.
Preferably, being integrated connects between first connecting portion and mounting portion, and is between second connecting portion and fixed part
Integration connection so that not only can to avoid due to caused by the frequent sexuality in bending section fracture, but also cause bending section with peace
Sealing shape between dress portion and fixed part is more preferable, also because the thickness of junction is thicker, so that endurance life higher.
Preferably, the intersection that first connecting portion and second connecting portion are connect with the first arc integrally is equipped with annular
First reinforcing ring so that first connecting portion and second connecting portion and the endurance life higher of the intersection of the first curved portion.
Preferably, the intersection that the first curved portion is connected with the second arc integrally is equipped with the second reinforcing ring of annular,
So that the first curved portion and the endurance life higher of the intersection of the second curved portion.
Preferably, the second curved portion recess is equipped with the third reinforcing ring of several annular settings so that can enhance second
The stretching-resisting bending-resisting folding endurance energy of curved portion.
The beneficial effects of the invention are as follows：By the way that the bending section between mounting portion and fixed part to be arranged to two layers of structure,
I.e. two layers first connecting portion being sequentially connected, the first curved portion and second connecting portion, and between first connecting portion and mounting portion
Intersection and second connecting portion can enhance bending section with the intersection of fixed part and intersect with fixed part and mounting portion
The thickness at place, so as to enhance the ability of its Resisting fractre, and during the fracture of the first curved portion of one of them in bending section, entirely
Diaphragm can also be supported and is continuing with, and so as to effectively prolong the service life, while also reserve repair to staff
Time avoids the air chamber of pneumatic diaphragm pump from being communicated with fluid chamber, causes the damage of bigger.
