It is controlled by the pressure oil of a pressure-distributing valve and is usually used in combination with an electromagnetic pressure-distributing valve. It can be used to remotely control the on / off operation of oil, gas, and water pipeline systems in hydropower stations. It is often used for clamping, control, lubrication, and other oil circuits.

[0003] The prior art discloses a hydraulic valve for an oil storage tank that is easy to install and has a publication number of CN112065799A, which relates to the technical field of hydraulic valves. The valve comprises a body, an upper valve body, a connecting mechanism, and a lower valve body. The upper valve body is fixedly arranged on the top of the body, the connecting mechanism is fixedly arranged on the top of the upper valve body, and the lower valve body is fixedly arranged on the bottom of the connecting mechanism. By providing an easy-to-install base, the device is effectively connected to the oil storage tank, and then, through the action of a spring clamping column and a fixed clamping plate, the upper oil inlet and the oil outlet of the oil storage tank are movably connected, and then the control dial is manipulated so that the upper valve body absorbs the oil into the hydraulic cavity provided therein through the action of the oil inlet channel, and then, through the hydraulic action of the device, the oil is discharged through the upper connecting piece or transmitted to the lower valve body through the action of the connecting mechanism for discharge, making the device easy to connect and install, convenient for its installation and use, saving its installation and assembly time, reducing cost investment, and effectively improving the practicality of the device.
