Abstract
The invention discloses an integral end face sealing structure which comprises a shell, a sealed body, a sealing gasket and a sealing gasket mounting groove, wherein the shell is designed symmetrically, the sealing gasket mounting groove is arranged in the shell, the sealing gasket is assembled and mounted in the sealing gasket mounting groove in the shell, and the sealed body is arranged at the upper part of the shell. The shell of the integrated end face sealing structure is made of plastic materials. The sealing gasket of the integral end face sealing structure is nitrile rubber or fluorine rubber. Compared with the prior art, the invention has the beneficial technical effects that: the integral end face sealing structure is suitable for the end face sealing structure of a multi-position multi-way valve, particularly the end face sealing structure of the multi-position multi-way valve with irregular end faces, and can improve the compactness of the product structural design and the manufacturability of assembly and effectively reduce the volume of the product on the premise of ensuring the end face sealing performance of the valve.
Description
Technical Field
The invention relates to the technical field of end face sealing of multi-position multi-way valves, in particular to an integral end face sealing structure.
Background
The multi-position multi-way valve generally requires that no leakage exists between the cavities in the working process, at present, the perimeter of the end face seal of the non-circular face of the multi-position multi-way valve is mostly calculated according to the related size of a seal face, and then the inner diameter and the outer diameter of an O-shaped seal ring are converted according to the same length. However, for a single multi-position multi-way valve, the end faces of at least 2 cavities need to be sealed by two or more O-shaped sealing rings, so that the whole product has a large volume and a poor structure compactness and is inconvenient for assembling the O-shaped sealing rings during structural design.
Disclosure of Invention
The invention mainly aims to solve the defects and provides the integral end face sealing structure which can improve the compactness of the structural design and the assembly manufacturability of a product and effectively reduce the volume of the product on the premise of ensuring the end face sealing performance of the non-circular face of the multi-position multi-way valve.
The utility model provides an integral end face seal structure, includes the casing, by seal, sealed pad and sealed pad installation slot, the casing is the symmetry design, the inside sealed pad installation slot that is provided with of casing, sealed pad assembly mounting is in sealed pad installation slot in the casing, by the seal setting on casing upper portion.
Further, the shell of the integral end face sealing structure is made of plastic materials.
Further, the sealing gasket of the integral end face sealing structure is nitrile rubber or fluorine rubber.
Compared with the prior art, the invention has the beneficial technical effects that: the integral end face sealing structure is suitable for the end face sealing structure of a multi-position multi-way valve, particularly the end face sealing structure of the multi-position multi-way valve with irregular end faces, and can improve the compactness of the product structural design and the manufacturability of assembly and effectively reduce the volume of the product on the premise of ensuring the end face sealing performance of the valve.

Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
The utility model provides an integral end face seal structure, includes casing 1, by seal 2, sealed 3 and sealed installation slot 4 of filling up, casing 1 is the symmetry design, 1 inside sealed installation slot 4 that is provided with of casing, sealed 3 assembly installations of filling up in sealed installation slot 4 of casing 1, set up on 1 upper portion of casing by seal 2. The housing 1 is of a plastics material. The sealing gasket 3 is nitrile rubber or fluorine rubber.
The sealing gasket is designed according to the relevant size of the position needing to be sealed by the sealing body, the groove is installed on the sealing gasket in the design on the shell, the groove size is designed according to the external dimension of the sealing body, a certain depth h is designed according to the requirement, the sealing gasket is limited, and the sealing gasket is assembled and installed in the corresponding groove of the shell.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
