Abstract

The invention relates to a volume control type valve. The valve comprises a controlled valve connected to a pipeline, an oil storage tank is connected to the controlled valve, a control valve body is connected to the oil storage tank, a control valve element is arranged in the control valve body, an output piston is connected into the oil storage tank in a sliding mode, the output piston divides the interior of the oil storage tank into a control oil cavity and a reset oil cavity, one end of the output piston extends out of the oil storage tank and is fixed with the controlled valve, a control oil pipe is fixedly arranged on the oil storage tank and is communicated with a control valve rod, a first residual oil port is formed in the control valve body, a residual oil pipe is connected to the valve body and is communicated with the first residual oil port of the control valve body, an oil inlet is formed in the side wall of the control valve body, an oil inlet pipe is fixedly arranged at the oil inlet of the control valve body, and the end, away from the control valve body, of the oil inlet pipe communicates with the reset oil cavity of the oil storage tank. The volume control type valve has the effects of small leakage, high efficiency, small processing difficulty and low cost of an upstream controller.

Description

technical field

[0001] The present application relates to the field of valves, in particular to a volume control valve. Background technique

[0002] Valve, a device that utilizes a moving part to open, close or partially block one or more openings or passages through which the flow of liquid, air or other air or bulk bulk materials can flow, be blocked or be regulated; also Refers to the spool, the moving part of the device.

[0003] The valve is fixedly connected to the pipeline and is used to control the outflow or blockage of fluid in the pipeline. Traditional valves include proportional valves, servo valves, relief valves, pressure reducing valves and shut-off valves. Proportional valves, servo valves, relief valves, pressure reducing valves and shut-off valves are all controlled by pressure or mechanically. There are defects such as large leakage, low efficiency, difficult processing, and expensive upstream controllers. Contents of the invention
