Description
Technical Field
The utility model discloses a high-pressure-resistant liquid leakage-proof diaphragm sealing structure, and belongs to the technical field of diaphragm pump sealing.
Background
The conventional diaphragm sealing structure is easy to leak liquid under high pressure, and the situation of sealing failure occurs, so that liquid loss or equipment damage is caused, and loss is caused.
Disclosure of Invention
The utility model overcomes the defects existing in the prior art, and provides the high-pressure-resistant and liquid-leakage-proof diaphragm sealing structure which is formed by adding side sealing by the traditional front sealing, and has better sealing effect and stronger pressure-bearing capacity.
In order to solve the technical problems, the utility model adopts the following technical scheme: the utility model provides a high pressure resistant leak protection liquid's diaphragm seal structure, includes valve plate, pump body and diaphragm, the setting of valve plate matching is in the upside of the pump body, the diaphragm sets up between valve plate and pump body, the upside of the pump body is provided with the space that holds the diaphragm with the contact surface middle part of valve plate, makes the setting that the diaphragm can match is in the pump body, the valve plate downside is provided with curved cavity, the diaphragm can match when upwards extruding laminating in the cavity, the annular is provided with the recess on the border of cavity, the border of the position matching diaphragm of recess, the border of diaphragm is integrative to be provided with upwards protruding, the laminating that the arch can match compresses tightly in the recess, forms sealedly.
The end face of the bulge is annularly provided with a semicircular sealing groove, a diaphragm sealing strip is arranged in the sealing groove, and the bulge tightly presses the sealing groove in the groove to form a seal.
The edge of the space for accommodating the diaphragm on the pump body sinks, and the sinking position and the groove are mutually aligned to form a limit structure with a flush side face.
Compared with the prior art, the utility model has the following beneficial effects: according to the utility model, the diaphragm sealing step is designed towards the cavity, when the pressure in the cavity is high, the diaphragm sealing ring is clamped on the valve plate, and the traditional front face seal is adopted, so that the side face seal is increased, the sealing effect is better, and the pressure bearing capacity is stronger.
Drawings
The utility model is further described below with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of the present utility model.
In the figure: the valve plate is 1, the pump body is 2, the diaphragm is 3, the cavity is 4, the groove is 5, the bulge is 6, the sealing groove is 7, and the diaphragm sealing strip is 8.
Description of the embodiments
As shown in fig. 1, the high-pressure-resistant liquid leakage-proof diaphragm sealing structure comprises a valve plate 1, a pump body 2 and a diaphragm 3, wherein the valve plate 1 is arranged on the upper side of the pump body 2 in a matched mode, the diaphragm 3 is arranged between the valve plate 1 and the pump body 2, a space for accommodating the diaphragm 3 is formed in the middle of a contact surface of the upper side of the pump body 2 and the valve plate 1, the diaphragm 3 can be arranged in the pump body 2 in a matched mode, an arc-shaped cavity 4 is formed in the lower side of the valve plate 1, the diaphragm 3 can be matched and attached to the cavity 4 when being extruded upwards, a groove 5 is formed in the edge of the cavity 4 in an annular mode, the edge of the groove 5 is matched with the edge of the diaphragm 3, an upward bulge 6 is integrally arranged on the edge of the diaphragm 3, and the bulge 6 can be matched and attached to the groove 5 to form sealing.
The end face of the bulge 6 is annularly provided with a semicircular sealing groove 7, a diaphragm sealing strip 8 is arranged in the sealing groove 7, and the bulge 6 tightly compresses the sealing groove 7 in the groove 5 to form a seal.
The edge of the space for accommodating the diaphragm 3 on the pump body 2 is sunk, and the sunk position and the groove 5 are mutually aligned to form a limit structure with a flush side face.
According to the utility model, the diaphragm sealing step is designed towards the cavity, when the pressure in the cavity is high, the diaphragm sealing ring is clamped on the valve plate, and the traditional front face seal is adopted, so that the side face seal is increased, the sealing effect is better, and the pressure bearing capacity is stronger.
The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model.
