Abstract

The invention relates to a hydraulic control valve assembly. The hydraulic control valve assembly comprises a control valve, a hydraulic cylinder and a connecting rod, wherein the control valve comprises a valve body, a valve rod and a valve plate, a medium flow channel is formed in the valve body, one end of the medium flow channel is an inlet end, the other end is an outlet end, and the valve plate is located between the inlet end and the outlet end; the hydraulic cylinder comprises a cylinder body, an inner cavity is formed in the cylinder body, a piston is arranged in the inner cavity and divides the inner cavity into a first cavity body and a second cavity body, the piston is provided with a piston rod extending into the first cavity body, the connecting rod is hinged with the piston rod, the first cavity body communicates with the outlet end, the second cavity body communicates with the inlet end, a connecting position of the valve plate and the valve rod is located above the center of the valve plate, and a drive structure is arranged between the connecting rod and the valve plate. With adoption of the technical scheme, the hydraulic control valve assembly can realize slow opening of the valve and can realize first rapid closing and then slow closing of the valve, so that a pipeline water hammer can be eliminated, and the safety of a pipeline system can be protected.

Description

technical field [0001] The invention relates to a hydraulic control valve assembly. Background technique [0002] The hydraulic control valve is installed at the outlet of the water pump, cooperates with the opening and closing of the water pump, and uses the pressure of the medium in the pipeline to control the opening and closing of the valve. At present, the hydraulic control valves used in the market cannot realize the slow opening of the valve, and when the valve is closed, the valve cannot be closed quickly and then slowly closed. Therefore, the water hammer in the pipeline cannot be eliminated, and the pipeline cannot be well protected system security. Contents of the invention [0003] Purpose of the present invention: In order to overcome the defects of the prior art, the present invention provides a hydraulic control valve assembly, which can not only realize the slow opening of the valve, but also realize the rapid closing and then slow closing of the valve, th...
