Background

The pilot operated check valve is a valve which can make the check valve reversely flow by controlling the pressure of fluid. The valve plays a more important role in the hydraulic support equipment of the coal mine machinery. The hydraulic control one-way valve is different from a common one-way valve in that a control oil way is added, when the control oil way is not communicated with pressure oil, the hydraulic control one-way valve works like the common one-way valve, and the pressure oil only flows to an oil outlet from an oil inlet and cannot reversely flow. When control pressure is input into the control oil way, the piston ejector rod moves rightwards under the action of pressure oil, the ejector rod is used for ejecting the one-way valve to enable the oil inlet and the oil outlet to be communicated, and if the oil outlet is larger than the oil inlet, the oil can flow reversely. It must be ensured that the pilot operated check valve has sufficient pilot pressure and absolutely no loss of pilot pressure is allowed. Care should be taken whether the control pressure meets the requirement for reverse opening. If the control of the hydraulic control one-way valve is led from the main system, the influence of the pressure change of the main system on the pressure of the control oil way is analyzed so as to avoid the misoperation of the hydraulic control one-way valve.
