Abstract
The utility model discloses a whole end face seal structure, include 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 the sealed pad installation slot in the casing, by the seal setting on casing upper portion. 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 utility model discloses the beneficial technological effect who gains does: 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 utility model relates to a many multi-ported valves's end face seal technical field, in particular to whole end face seal 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.
SUMMERY OF THE UTILITY MODEL
The utility model discloses not enough above the main objective is solved, provide one kind and guarantee under the prerequisite of the terminal surface sealing performance of many multi-way valve non-circular faces, improve product structural design's compactedness and the manufacturability of assembly, effectively reduce the whole end face seal structure of the volume of product simultaneously.
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 utility model discloses the beneficial technological effect who gains does: 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.
