Abstract

The invention discloses a piston-type hydraulic control valve. The bonnet is fixed on the top of the valve body through bolts. A switch device is fixed inside the bonnet. The switch device includes a drive device and a control device. The drive device includes a drive motor, a mounting plate, Threaded rod and sleeve, the driving motor is fixed on the top of the mounting plate, the mounting plate is fixed inside the bonnet, the output shaft of the driving motor passes through the mounting plate and fixed with the threaded rod, and the connection between the output shaft of the driving motor and the mounting plate passes through The bearing is rotated and connected, and the end of the threaded rod away from the drive motor is sleeved in the sleeve. The inner side of the sleeve is provided with internal threads. This piston type hydraulic control valve controls the work of the drive motor through the control panel to realize the control of the valve body switch. Automatic control, through the buffer component to generate elastic force to support the spring applied by the sleeve, to prevent the damage of the pressure sensor caused by the instantaneous excessive tension of the sleeve, and also to make the pressure sensor bear the pressure more slowly, and the detection data is more accurate.

Description

technical field [0001] The invention relates to the technical field of hydraulic control valves, in particular to a piston-type hydraulic control valve. Background technique [0002] The hydraulic control valve is a valve controlled by water pressure. The hydraulic control valve is composed of a main valve and its attached conduit, pilot valve, needle valve, ball valve and pressure gauge. According to different purposes, functions and places, it can be evolved into remote control float valve, pressure reducing valve, slow closing check valve, flow control valve, pressure relief valve, hydraulic electric control valve, water pump control valve, etc. [0003] Most of the hydraulic control valves in the prior art are manually controlled, which consumes a lot of labor, and because the manual control speed is slow, it is not convenient for the staff to control multiple sets of hydraulic control valves at the same time, so that the staff can control the hydraulic control valves. ...
