| Hydraulic control valve is a valve for water pressure control, which consists of a main valve and its accompanying pipes, guide valves, needle valves, ball valves, and pressure gauges. It can be evolved into remote control according to different usage purposes, functions, and locationsfloat valvePressure reducing valve, slow closing check valve, flow control valve, pressure relief valve, hydraulic electric control valve, etc. Hydraulic control valves are divided into diaphragm type and piston type, with the same working principle. They are both powered by the upstream and downstream pressure difference △ P, controlled by a pilot valve to enable hydraulic differential operation of the diaphragm (piston), fully regulated by hydraulic automatic control, so that the main valve disc can be fully opened or fully closed or in a regulating state. When the pressure water entering the control chamber above the diaphragm (piston) is discharged to the atmosphere or downstream low-pressure area, the pressure value acting on the bottom of the valve disc and below the diaphragm is greater than the pressure value above, so push the main valve disc to the fully open position; When the pressure water entering the control chamber above the diaphragm (piston) cannot be discharged to the atmosphere or downstream low-pressure area, the pressure value acting above the diaphragm (piston) is greater than the pressure value below, so the main valve disc will be pressed to the fully closed position; When the pressure value in the control chamber above the diaphragm (piston) is between the inlet pressure and the outlet pressure, the main valve disc is in a regulating state, and its regulating position depends on the joint control of the needle valve and the adjustable pilot valve in the conduit system. Adjustable pilot valves can open or close their own small valve ports according to the downstream outlet pressure, thereby changing the pressure value of the control chamber above the diaphragm (piston) and controlling the adjustment position of the square valve disc. |
