AI Technical Summary
Technical Problem
In traditional multi-way reversing sealing valves, the return spring is easily damaged, resulting in the boom valve core being unable to return to position, and the internal hydraulic oil needs to be cleared when replacing it. The steps are cumbersome and the efficiency is not high.
Method used
A multi-way reversing seal valve is designed, using two sets of return springs, which increases the restoration force and fixes one end of the boom valve core through the insert rod to facilitate removal of the other end for spring replacement without clearing the hydraulic oil.
Benefits of technology
It improves the recovery force and operating speed of the boom valve core, simplifies the spring replacement process, improves working efficiency, and avoids hydraulic oil leakage.

Abstract
The utility model discloses a multi-way reversing sealing valve which comprises a valve body and a movable arm valve element, and a plurality of flow channels are formed in the valve body and communicated with the movable arm valve element. The movable arm valve core consists of a front end part, a rear end part and a middle sealing part; the front end part and the rear end part of the movable arm valve core are exposed out of the outer side of the valve body and are wrapped and covered by the cover body; the diameters of the front end part and the rear end part are smaller than that of the middle sealing part, and the front end part, the rear end part and the middle sealing part are connected to form a fixed step; main bodies of the front end part and the rear end part of the movable arm valve core are provided with through holes; the cover body is composed of a main cover body and an auxiliary cover body, a limiting protrusion is arranged between the main cover body and the auxiliary cover body, and a spring is arranged between the limiting protrusion and the fixing step. A fixing hole is formed in the auxiliary cover body; inserting rods are inserted into the fixing holes in a penetrating mode and connected with the through holes in the main body of the front end and the rear end in a matched mode. The double spring sets are adopted, so that the restoring force is large, and the damage rate is reduced; and meanwhile, the cover body is optimally designed and is convenient to disassemble and assemble, and the efficiency is greatly improved.
