Abstract
The utility model overcomes the defects existing in the prior art, provides the high-pressure-resistant diaphragm pump valve sheet structure, increases the supporting force of the valve sheet, ensures that the valve sheet is not easy to deform and damage, greatly prolongs the service life of the valve sheet, and effectively prolongs the service life of the pump; in order to solve the technical problems, the utility model adopts the following technical scheme: the high-pressure-resistant diaphragm pump valve sheet structure comprises a valve sheet body, wherein one side of the middle surface of the valve sheet body is provided with a metal sheet in a matching manner, and the edge of the metal sheet is wrapped with a rubber layer, so that the metal sheet is completely attached to the valve sheet body; the utility model can be widely applied to the field of diaphragm pumps.
Description
Technical Field
The utility model relates to a high-pressure-resistant diaphragm pump valve structure, and belongs to the technical field of diaphragm pumps.
Background
In the working process of the existing high-pressure diaphragm pump, the valve plate is continuously and frequently subjected to pressure so as to deform and provide pressure, and after the time is long, the valve plate is damaged by tearing and the like, so that the pump is damaged.
Disclosure of Invention
The utility model overcomes the defects existing in the prior art, provides the high-pressure-resistant diaphragm pump valve sheet structure, increases the supporting force of the valve sheet, ensures that the valve sheet is not easy to deform and damage, greatly prolongs the service life of the valve sheet, and effectively prolongs the service life of the pump.
In order to solve the technical problems, the utility model adopts the following technical scheme: the utility model provides a diaphragm pump valve sheet structure of high pressure resistant, includes the valve block body, middle part surface one side of valve block body matches and is provided with foil, foil's edge parcel is provided with the rubber layer for foil laminates the valve block body setting completely.
Further, the whole metal sheet is covered and wrapped by a rubber layer.
Further, one surface of the metal sheet completely wrapped by rubber is attached to the runner outlet of the valve upper plate or the valve lower plate.
Compared with the prior art, the utility model has the following beneficial effects: according to the valve, the metal sheet is arranged in the middle of the valve plate, and the rubber layer is wrapped outside the metal sheet, so that the valve plate is not easy to deform and damage due to metal support during working, the sealing performance of the valve can be met by the outer rubber layer, the service life of the valve plate is greatly prolonged, and the service life of the pump is effectively prolonged.
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.
Fig. 2 is a schematic rear view of the present utility model.
Fig. 3 is an exploded view of the present utility model.
FIG. 4 is an exploded view of the present utility model in use.
In the figure: the valve plate is characterized in that 1 is a valve plate body, 2 is a metal sheet, and 3 is a rubber layer.
Description of the embodiments
The utility model is further illustrated below in conjunction with specific examples.
As shown in fig. 1 to 4, the utility model discloses a high-pressure-resistant diaphragm pump valve sheet structure, which comprises a valve sheet body 1, wherein one side of the middle surface of the valve sheet body 1 is provided with a metal sheet 2 in a matching manner, the metal sheet 2 is provided with a plurality of through holes, the metal sheet 2 is inserted into the metal sheet body through interference fit with rubber protrusions on the outer side of the valve sheet body 1, and a rubber layer 3 is arranged in a nesting manner of the metal sheet 2, so that the metal sheet 2 is completely attached to the valve sheet body 1.
The whole metal sheet 2 is covered and wrapped by the rubber layer 3, and the metal sheet 2 and the valve plate body 1 are completely embedded together.
One surface of the metal sheet 2 completely wrapped by rubber is attached to the runner outlet of the valve upper plate or the valve lower plate, so that the metal sheet 2 is in contact with the valve cavity and bears the most direct impact.
The utility model is provided with a plurality of small holes on the surface of the metal sheet 2, which is convenient for the metal sheet 2 to be firmly combined and is also convenient for demoulding when being cast and molded with the valve plate body 1.
In the utility model, the metal sheet 2 is arranged between the valve lower plate and the valve upper plate, and the metal sheet 2 is arranged between the valve upper plate and the valve lower plate in a positive-negative way, so that the metal sheet 2 is combined with the flow passage structures of the valve lower plate and the valve upper plate to realize the function of the one-way valve. The side of the foil 2 completely covered by rubber is attached to the flow channel outlet of the valve upper plate (or valve lower plate) to ensure a reliable seal.
The metal sheet is arranged in the middle of the valve plate, the rubber layer is wrapped outside the metal sheet, and the valve plate is not easy to deform and damage due to metal support during working. While the outer rubber layer may satisfy the sealability of the valve.
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.
