Abstract

The multi-way reversing valve comprises an oil inlet unit and an oil return unit, a plurality of working units are connected between the oil inlet unit and the oil return unit in series, the oil inlet unit comprises an oil inlet valve body and a main oil inlet formed in the oil inlet valve body, the oil return unit comprises an oil return valve body and a main oil return opening formed in the oil return valve body, and each working unit comprises a working valve body. And a valve core is arranged in the working valve body. In the using process, the corresponding number of working units can be arranged according to the number of executive components and requirements, universality is high, and the working valve body is simple in structure, quite convenient to machine and low in manufacturing cost. When the valve element is in the neutral position state, the multi-way reversing valve is in the unloading state, an electromagnetic unloading valve does not need to be additionally arranged, the structure is simplified, control signals are reduced, and control of an upper computer is simpler; and the sandwich valve can be directly added on the working valve body, and a non-standard oil path block or a matched valve does not need to be developed, so that the universality is high.

Description

technical field [0001] The present application relates to the field of hydraulic control components, in particular to a multi-way reversing valve. Background technique [0002] The multi-way reversing valve refers to a multi-way combination valve composed of two or more reversing valves as the main body, and according to different requirements, auxiliary devices such as safety valves, check valves, and oil filling valves are added. The multi-way reversing valve is an integrated valve composed of several single-connected reversing valves, oil inlet joints, and oil return joints. [0003] Existing multi-way directional valves mainly include integral multi-way valves and slice multi-way valves. Integral multi-way valve integrates each reversing valve, oil inlet, oil return and auxiliary valves with different functions into one valve body. It has the advantages of compact structure, light weight, and small pressure loss. [0004] However, since all the reversing valves are co...
