Abstract
The invention discloses a kind of diaphragm pump diaphragms, belong to pump technical field, in order to increase now septate service life, improve service life or the overhaul time of diaphragm pump, convenient to replace to diaphragm；Seperated design is carried out by the diaphragm to diaphragm pump, the fatigue resistance of diaphragm is enhanced, substantially increases the service life of diaphragm；And replace diaphragm be only need to change part on the outside of diaphragm can, be convenient for changing, reduce waste, reduce the use cost of diaphragm pump.
Description
Technical field
The invention belongs to pump technical fields, are related to a kind of positive displacement pump, and in particular to a kind of diaphragm pump diaphragm.
Background technique
Existing common water pump is mostly to drive liquid using propeller or carried out using atmospheric pressure, and diaphragm pump is then benefit
Pump pressure imbalance is caused to convey material in the intracorporal movement of pump with diaphragm.Since the diaphragm of diaphragm pump is the pass of diaphragm pump
One of key part.Diaphragm movement frequency is very frequent, this just needs to increase the service life of diaphragm to improve the use of diaphragm pump
Service life or overhaul time.After diaphragm failures, it is necessary to diaphragm is replaced, it is more wasteful in this way.
Summary of the invention
According to the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is to propose a kind of diaphragm pump with every
Film carries out seperated design by the diaphragm to diaphragm pump, enhances the fatigue resistance of diaphragm, substantially increase the use of diaphragm
Service life.And replace diaphragm be only need to change part on the outside of diaphragm can, reduce waste.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention are as follows:
A kind of diaphragm pump diaphragm, the diaphragm include outer diaphragm and diaphragm body, the downward projection of diaphragm body be it is discoid,
The outer diaphragm is ring structure, and the outside of diaphragm body is arranged in outer diaphragm.
The center of circle of the diaphragm body is equipped with mounting hole.It is additionally provided with above the mounting hole circular for installing check valve
Counterbore.The diameter of the counterbore is greater than the diameter of mounting hole.The bottom of the counterbore is equipped with channel, the axis of counterbore and installation
The axis in hole is overlapped.The outer diaphragm inner wall is equipped with protrusion；The periphery of diaphragm body be equipped with groove, outer diaphragm protrusion insertion every
In the groove of membrane body.The opposite two side walls of the groove of the diaphragm body are equipped with conical indentation, the bottom of the groove of diaphragm body
For plane；Two sides of the protrusion on outer diaphragm inner wall are equipped with tapered protrusion, and the top of tapered protrusion is plane；The taper
The angle of wedge of protrusion is greater than the angle of wedge of conical indentation.The angle of the conical indentation angle of wedge is 88 degree, the angle of the tapered protrusion angle of wedge
It is 90 degree.The material of the outer diaphragm is rubber industry, and the material of the diaphragm body is metal, and the material of the diaphragm body is not
Become rusty steel.
The medicine have the advantages that a kind of diaphragm pump diaphragm, carries out seperated design, enhancing by the diaphragm to diaphragm pump
The fatigue resistance of diaphragm, substantially increases the service life of diaphragm.And replacement diaphragm is the portion only needed to change on the outside of diaphragm
Point can, reduce waste, reduce the use cost of diaphragm pump.
Detailed description of the invention
Content expressed by this specification attached drawing and the label in figure are briefly described below:
Fig. 1 is the structural schematic diagram of a specific embodiment of the invention diaphragm pump diaphragm.
1 in figure, outer diaphragm, 2, diaphragm body.
Specific embodiment
Below against attached drawing, by the description of the embodiment, for example related each component of a specific embodiment of the invention
Shape, construction, the mutual alignment between each section and connection relationship, the effect of each section and working principle, manufacturing process and
Operate with method etc., is described in further detail, to help those skilled in the art to inventive concept of the invention, technology
Scheme has more complete, accurate and deep understanding.
As shown in Figure 1, a kind of diaphragm pump diaphragm, including outer diaphragm 1 and diaphragm body 2.
The downward projection of the diaphragm body 2 be it is discoid, the center of circle of diaphragm body 2 is equipped with mounting hole, 2 mounting hole of diaphragm body
Top is additionally provided with the circular counterbore for being used to install check valve, and the diameter of counterbore is greater than the diameter of mounting hole.The bottom of counterbore is set
There is channel, the axis of counterbore is overlapped with the axis of mounting hole.Diaphragm body 2 is equipped with outer diaphragm 1, and the outer diaphragm 1 is ring junction
Structure, inner wall are equipped with protrusion.The periphery of diaphragm body 2 is equipped with groove, and the protrusion of outer diaphragm 1 is inserted into the groove of diaphragm body 2.
In order to enable the long service life of diaphragm, and replace conveniently, the material of the outer diaphragm 1 is rubber industry, described
The material of diaphragm body 2 is metal, and the material of preferred diaphragm body 2 is stainless steel.Such diaphragm has enough elasticity to have foot again
Enough rigidity.And diaphragm body 2 is hardly damaged, outer diaphragm 1 is easily changed.And after diaphragm is ineffective, by replacing outer diaphragm 1,
Have so that diaphragm takes on an entirely new look, can continue to use, greatly reduce the use cost of diaphragm, that is, reduce the use of diaphragm pump
Cost.
In order to enable firmly installing and improving the fatigue resistance of outer diaphragm 1, diaphragm body 2 between outer diaphragm 1 and diaphragm body 2
The opposite two side walls of groove be equipped with conical indentation, the angle of the conical indentation angle of wedge is 88 degree, the bottom of the groove of diaphragm body 2
Portion is plane.Two sides of the protrusion on outer 1 inner wall of diaphragm are equipped with tapered protrusion, and the angle of the tapered protrusion angle of wedge is 90 degree,
The top of tapered protrusion is plane.After outer diaphragm 1 is assembled on diaphragm body 2, negative stress, outer diaphragm are formed inside tapered protrusion
1 fatigue resistance greatly improves.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out is used, or without changing
It is within the scope of the present invention into the conception and technical scheme of the invention are directly applied to other occasions.This hair
Bright protection scope should be determined by the scope of protection defined in the claims.
