Description
Technical Field
The utility model relates to the technical field of diaphragm pump accessories, in particular to a rubber diaphragm.
Background
The pneumatic diaphragm pump is a new type of conveying machinery, and adopts compressed air as power source, and can pump out various corrosive liquids, granular liquids, high viscosity, volatile, inflammable and highly toxic liquids.
When the diaphragm pump works, the crank connecting rod mechanism drives the plunger to do reciprocating motion under the drive of the motor, and the motion of the plunger is transmitted to the diaphragm through working liquid (generally oil) in the hydraulic cylinder, so that the diaphragm is driven to move back and forth.
Because the diaphragm can expand and bulge back and forth, the problem that the existing rubber diaphragm is easy to fatigue and has excessive expansion amplitude after long-term use is caused, so that the diaphragm can possibly crack, the joint of the edge part of the diaphragm and the fixing part can possibly be damaged easily, the use precision of the diaphragm pump is reduced, and the failure rate of the diaphragm pump is improved, so that it is necessary to design a rubber diaphragm to solve the problem.
Disclosure of Invention
The present utility model is directed to a rubber membrane to solve the above-mentioned problems in the prior art.
In order to achieve the above purpose, the present utility model provides the following technical solutions:
the utility model provides a rubber diaphragm, includes the mounting panel, circular hole has been seted up on the surface of mounting panel, circular hole internal fixation has circular rubber diaphragm, and the equal fixedly connected with arc blend stop of upper and lower both sides of mounting panel, the annular blend stop of equal fixedly connected with and circular hole site same central axis on two arc blend stops, circular rubber diaphragm can conflict on corresponding arc blend stop and annular blend stop on its surface when the inflation.
Preferably, the height of the arc-shaped barrier strip is 1/3 of the diameter of the circular rubber diaphragm, and the circular rubber diaphragm can be expanded by a reasonable amplitude.
Preferably, the diameter of the annular barrier strip is 2/3 of the diameter of the circular rubber diaphragm.
Preferably, the top of the mounting plate is fixedly connected with two bilateral symmetry support plates, and each support plate is provided with two holes which are symmetrical and used for inserting bolts, so that the bolts can conveniently pass through the holes and the mounting plate is mounted in the diaphragm pump.
Preferably, the thickness of the circular rubber diaphragm is at least 5mm, so that the possibility of cracking and breakage of the circular rubber diaphragm is reduced.
Preferably, the thickness of the arc-shaped barrier strip and the annular barrier strip is 10mm so as to adapt to the pressure caused by the expansion of the circular rubber membrane.
Compared with the prior art, the utility model has the beneficial effects that:
when the round rubber diaphragm is inflated back and forth, the surface of the round rubber diaphragm can expand and deform and is abutted against the arc-shaped baffle strip and the annular baffle strip, and the arc-shaped baffle strip and the annular baffle strip can limit the expansion range of the round rubber diaphragm so as to prevent the round rubber diaphragm from excessively expanding and deforming, reduce the possibility of cracking of the round rubber diaphragm, and avoid the problem that the joint of the round rubber diaphragm and a round hole is damaged due to overlarge expansion range when the round rubber diaphragm is inflated.

Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
It will be apparent that numerous specific details are set forth in the following description in order to provide a thorough understanding of the present utility model, however, the present utility model may be practiced in other ways than as described herein, and therefore the present utility model is not limited to the specific embodiments of the present disclosure.
Referring to fig. 1-4, the present utility model provides a rubber diaphragm: including mounting panel 1, circular hole has been seted up on the surface of mounting panel 1, circular hole internal fixation has circular rubber diaphragm 2, and the equal fixedly connected with arc blend stop 3 of the upper and lower both sides of mounting panel 1, equal fixedly connected with and circular hole site's annular blend stop 4 on two arc blend stops 3, circular rubber diaphragm 2 can conflict on corresponding arc blend stop 3 and annular blend stop 4 when the inflation, through such design, when circular rubber diaphragm 2 is in the back and forth drumming, its surface can the inflation deformation and conflict on arc blend stop 3 and annular blend stop 4, arc blend stop 3 and annular blend stop 4 then can play the effect of restriction to the inflation range of circular rubber diaphragm 2, in order to prevent the excessive inflation deformation of circular rubber diaphragm 2, reduce the possibility that circular rubber diaphragm 2 produced the crackle, and avoided the inflation range too big and lead to its problem with the junction damage in circular hole when circular rubber diaphragm 2 drumming.
Referring to fig. 1, the height of the arc-shaped barrier strip 3 is 1/3 of the diameter of the circular rubber membrane 2, so that a reasonable amplitude can be formed in the arc-shaped barrier strip 3 when the circular rubber membrane 2 expands.
Meanwhile, the diameter of the annular barrier strip 4 is 2/3 of the diameter of the circular rubber diaphragm 2, and the design is more reasonable.
In some embodiments, two support plates 5 are fixedly connected to the top of the mounting plate 1, and two holes 6 which are symmetrical and used for inserting bolts are formed in each support plate 5, so that the bolts can conveniently pass through the holes 6 and the mounting plate 1 can be mounted in the diaphragm pump.
