Braking and reversing integrated valve assembly

Abstract

The invention relates to a braking and reversing integrated valve assembly. According to the technical scheme, the braking and reversing integrated valve assembly comprises a valve body and integrated valves, a cavity hole is formed in the valve body, the integrated valves of a plurality of sets are inserted into the cavity hole, the integrated valves are connected with a plurality of executing elements respectively, the integrated valves comprise first inserting pieces and second inserting pieces, the first inserting pieces and the second inserting pieces are connected with solenoid valves respectively, a high-pressure opening and a low-pressure opening are formed in the valve body, the inlet ends of the first inserting pieces are connected with the high-pressure opening, the inlet ends of the second inserting pieces are connected with the low-pressure opening, the outlet ends of the first inserting pieces and the outlet ends of the second inserting pieces are connected in parallel and then are connected into dynamic valves, the dynamic valves are connected with a manual valve, the dynamic valves are controlled by the manual valve to be opened and closed, and outlets of the dynamic valves are connected with inlets of the executing elements. The braking and reversing integrated valve assembly has the advantages that the problem that no large-drift-diameter multi-way valve exists on the hydraulic part market is solved, the valve body and the inserting pieces are rigidly sealed, the inserting pieces have the self-locking function, and zero leakage is achieved.

Description

technical field [0001] The invention relates to a large actuator control device with a large diameter, in particular to a brake reversing integrated valve assembly. Background technique [0002] At present, the diameter of hydraulic valves at home and abroad is mostly not greater than 32mm, so for some control systems that require large flow, no suitable hydraulic components can be found for control, especially the large diameter reversing valve with the same function as a multi-way valve. The market is almost blank, so many hydraulic systems that require large flow usually adopt the method of valve parallel connection to increase the flow capacity, which leads to more complex systems and more control pipelines, which affects the working efficiency of hydraulic valves. Contents of the invention [0003] The purpose of the present invention is to provide a brake reversing integrated valve assembly to improve the working efficiency of the hydraulic valve in view of the above...
