Abstract
A diaphragm sheet of a pneumatic diaphragm pump is in the shape of a round disc. A fixed ring is arranged at the outer edge of the diaphragm sheet; a mounting position is formed in the central position of the diaphragm sheet; a round hole is formed in the central part of the mounting position; an annular bending part is arranged between the fixed ring and the mounting position; a plurality of reinforcing ribs are arranged inside the annular bending part; two sides of the joint part of the annular bent part and the fixed ring, and two sides of the joint part of the annular bent part and the mounting position, are made to be arc-shaped; a layer of weaving net is clamped in the central position of the diaphragm; and the weaving net is made of nylons or materials such as cotton, hemp, and the like. Since the weaving net in the central position of the diaphragm is clamped in the position one half of the thickness of the diaphragm sheet, the stresses on the two sides of the diaphragm sheet are relatively even; and in addition, two surfaces of an transitional part are made to be arc-shaped, so that the phenomena of the rupture along the interior angle line is reduced.
Description
Technical field
The utility model relates to a kind of pair of chamber membrane pump with pneumatic drive, the especially diaphragm of a kind of pair of chamber membrane pump with pneumatic drive.
Background technique
Diaphragm in the membrane pump with pneumatic drive is the main working parts of membrane pump with pneumatic drive, membrane pump with pneumatic drive is to utilize diaphragm that the pump housing is separated into two cavitys, a liquid container and an air cavity, the neutral position of diaphragm sheet is to connect piston rod, be transported to the power that pressurized air provided in the membrane pump with pneumatic drive, act on the diaphragm sheet, diaphragm is swung by piston rod, at this moment, corresponding variation will take place in the volume of the liquid container of diaphragm both sides and air cavity.Membrane pump with pneumatic drive is exactly the Volume Changes by liquid container, under the cooperation of import valve ball and outlet valve ball liquid is released.Diaphragm in the membrane pump with pneumatic drive is a main working parts, is easy to damage, and directly affects the working efficiency of membrane pump with pneumatic drive the working life of diaphragm.Existing diaphragm is made with rubber material, outer rim is one outer installation position of ring-type, the central position is interior installation position, interior installation position circle centre position has a circular hole, is curved part between interior installation position and the outer installation position, the position of stretching during curved part is just worked, outer installation position is thicker than curved part, there is interior linea angulata outer installation position with the transition intersection of curved part, and after diaphragm work a period of time, outer installation position and curved part intersection will split along interior linea angulata.In addition, accompanies nylon wire in the middle of the existing diaphragm, and this layer nylon wire is laid on 1/3rd places of diaphragm from this air chamber latallae thickness, the suffered tension force of nylon wire is different like this, the curved part bending of diaphragm is different, causes the piston rod distortion of connection, crooked or fracture easily.
Summary of the invention
Split easily and the problem that causes piston rod distortion, bending or fracture easily in order to solve prior art installation position, China and foreign countries and curved part intersection, the utility model provides a kind of diaphragm of novel pneumatic diaphragm pump.
The technological scheme that the utility model technical solution problem is adopted is: a kind of diaphragm of membrane pump with pneumatic drive, make with rubber material, be shaped as disc, the outward edge of disc-shaped diaphragm sheet is one retaining ring, the disconnected cross section of retaining ring is slightly circular, is convenient to fixedly connected with the pump housing and seal.The center portion of diaphragm is the installation position, and circle centre position has a circular hole, be used for piston rod on good combination of fixed plate.It between retaining ring and the installation position toroidal bend portion, toroidal bend portion is an annular " U " shape groove, size, the degree of depth and the radian of " U " shape groove are to determine according to the diameter and the motion amplitude of diaphragm, toroidal bend portion is the position of fore and aft motion on the diaphragm, it in the work position of bearing the stress maximum, in order to increase the intensity of curved part, in " U " shape groove, be provided with many strengthening rib.The connecting part of curved part and retaining ring is called outer transition part, the connecting part of curved part and installation position is called interior transition part, arc shape is all made on the two sides of interior transition part and outer transition part, the significantly interior linea angulata of annular so just can not occur, can effectively avoid the phenomenon of splitting along interior linea angulata easily after diaphragm work a period of time.For intensity that increases diaphragm and the working life that prolongs diaphragm, with in the process of Mold Making diaphragm in therebetween one deck mesh grid of diaphragm, materials such as mesh grid use nylon or cotton, fiber crops are made into, mesh grid is laid on the middle (1/2nd places of diaphragm thickness) of diaphragm, and the diaphragm two sides is subjected to stress ratio more even like this.
The beneficial effects of the utility model are: because the mesh grid in the middle of the diaphragm of membrane pump with pneumatic drive of the present utility model, be laid on 1/2nd places of diaphragm thickness, the diaphragm two sides is subjected to stress ratio more even, in addition, arc shape is all made on the two sides of transition part, reduces the phenomenon that appearance is split along interior linea angulata.

Embodiment
As shown in Figure 1 and Figure 2, a kind of diaphragm of membrane pump with pneumatic drive is made with rubber material, is shaped as disc, and the outward edge of disc diaphragm is one retaining ring 1, and the disconnected cross section of retaining ring 1 is slightly circular, is convenient to fixedly connected with the pump housing and seal.The center portion of diaphragm is installation position 6, and circle centre position has a circular hole 7, be used for piston rod on good combination of fixed plate.Be toroidal bend portion 3 between retaining ring 1 and the installation position 6, toroidal bend portion 3 is an annular " U " shape grooves, size, the degree of depth and the radian of annular " U " shape groove are to determine according to the diameter and the motion amplitude of diaphragm, toroidal bend portion 3 is positions of fore and aft motion on the diaphragm, it in the work position of bearing the stress maximum, in order to increase the intensity of toroidal bend portion 3, in " U " shape groove, be provided with many strengthening rib 4.Toroidal bend portion 3 is outer transition part 2 with the connecting part of retaining ring 1, curved part 3 is interior transition part 5 with the connecting part of installation position 6, arc shape is all made on the two sides of interior transition part 5 and outer transition part 2, the significantly interior linea angulata of annular so just can not occur, can effectively avoid the phenomenon of splitting along interior linea angulata easily after diaphragm work a period of time.For intensity that increases diaphragm and the working life that prolongs diaphragm, in the process of making diaphragm, therebetween one deck mesh grid 8 at diaphragm, mesh grid 8 is to use materials such as nylon or cotton, fiber crops to be made into, mesh grid 8 is folded in the middle (1/2nd places of diaphragm thickness) of diaphragm, be subjected to stress just relatively evenly when work in the diaphragm two sides like this, can effectively prolong the working life of barrier film fragment.
