Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a structure for solving the problem of rust and oil leakage between valve body pieces of a multi-way valve. Background Art

[0002] At present, the convex surface between the valve body plates of the multi-way valve is small, which will cause the non-convex surface to be not fully painted during the painting process; the valve body air avoidance groove is straight, which will cause the cleaning liquid to enter the valve body during the spraying process; the sealing ring groove between the plates is not connected to the T-port, which will cause the leaked oil to seep out easily. This structure is very likely to cause rust and oil leakage between the plates.

[0003] In summary, the utility model solves the existing problem by designing a structure to solve the problem of rust and oil leakage between valve body plates of a multi-way valve. Utility Model Content

[0004] The utility model aims to provide a structure for solving the problem of rust and oil seepage between valve body plates of a multi-way valve, so as to solve the problems raised in the above-mentioned background technology.

[0006] A structure for solving the problem of rust and oil seepage between valve body plates of a multi-way valve comprises a multi-way valve body, wherein the outer wall of the multi-way valve body is provided with an inter-plate boss for preventing rust and oil seepage between valve body plates of the multi-way valve body, a non-straight avoidance groove is provided on the outer wall of the multi-way valve body and corresponding to the inter-plate boss, an inter-plate sealing ring groove is provided at the center of the inter-plate boss, a through hole communicating with the T-port identical to the T-port is provided in the inner ring of the inter-plate sealing ring groove and located on the multi-way valve body, wherein the inter-plate sealing ring groove and the through hole communicating with the T-port are a connected structure.

[0007] As a preferred solution of the utility model, the air avoidance groove is a rectangular structure, and the air avoidance groove is transversely arranged on the valve body of the multi-way valve.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] In the utility model, the size of the boss between the plates is increased by design, so that the non-boss surface can be sprayed with paint during painting, and thus the plates between the valve bodies of the multi-way valve will not rust or leak oil;

[0010] The air avoidance groove is changed to a non-straight-through one, so that during the spraying process of the paint spraying line, the cleaning liquid will not enter the multi-way valve body from the air avoidance groove, and the phenomenon of rust and oil leakage between the multi-way valve body pieces can also be avoided;

[0011] The sealing ring groove between the plates is changed to communicate with the through hole communicating with the T port, so that the leaked oil can return to the T port, and oil leakage between the plates of the multi-way valve body can also be avoided. BRIEF DESCRIPTION OF THE DRAWINGS
