Problems solved by technology

[0002] At present, the control valves used on forklifts are mostly composed of three parts: valve body, shell and electromagnetic reversing valve. Two buffer valves and a constant pressure valve are installed in the valve body. In case of failure, due to the combined structure, it needs to be disassembled to determine the location of the failure. It is very inconvenient to repair, and it is bulky and takes up a lot of space.

Abstract

The invention relates to an electromagnetic hydraulic combined control valve. The electromagnetic hydraulic combined control valve comprises a valve body and a magnetic exchange valve; a cushion valve, a constant pressure valve and an inching valve are arranged inside the valve body in a parallel and concentrate mode; the cushion valve is capable of respectively performing buffering on a forward gear and a backward gear; the magnetic exchange valve is installed on the valve body; a main oil circuit is connected into an oil circuit input port sequentially through the inching valve and the cushion valve; and in the main oil circuit, the constant pressure valve is arranged on one side of an oil circuit inlet end of the inching valve. The electromagnetic hydraulic combined control valve has the advantage of being convenient to overhaul due to the facts that the oil circuit is simple and the control valve size is reduced by one third.

Description

technical field [0001] The invention relates to an electromagnetic-hydraulic combination control valve, in particular to a control valve for forklifts. Background technique [0002] At present, the control valves used on forklifts are mostly composed of three parts: valve body, shell and electromagnetic reversing valve. Two buffer valves and a constant pressure valve are installed in the valve body. When a fault occurs, because it is a combined structure, it needs to be disassembled to determine where the fault occurs. It is very inconvenient to repair, and it is bulky and takes up a lot of space. Contents of the invention [0003] The present invention aims at the shortcomings of the above-mentioned existing problems, and provides an electromagnetic-hydraulic combined control valve with simple structure, simple oil circuit, small volume, and convenient installation and maintenance. [0004] The present invention adopts the following technical solutions: an electromagneti...
