Hydraulic control valve is based on medium pressure pipeline as the driving force, opening and closing, regulating the valve. It consists of a main valve and attached to the catheter, needle valve, ball valve and pressure gauge, etc., depending on the purpose of use, functional areas can be evolved into a remote control float valve, pressure relief valve, slow closing check valve, flow control valve , Pressure relief valve, hydraulic electric control valve, emergency shut-off valve and so on. Pilot valve with the media level and pressure changes and action, as a large number of pilot valve can be used alone or a few combinations, you can make the main valve access to the water level and pressure and flow and other separate and complex adjustment function . However, the main valve body similar to the globe valve, the valve is fully open, the pressure loss is much greater than other valves, and each opening loss coefficient is closer to fully closed state, the more drastic increase in valve diameter larger Significant. With the characteristics of the valve, the valve close to the action of acceleration, prone to the impact of water hammer, close to fully closed, the slower the better the valve action, so set in the valve flap throttling device. In addition, the pilot valve throttling and the action part should try to avoid setting a special small aperture to avoid clogging. If necessary, add filters, regular maintenance and set up by-pass pipeline. Hydraulic control valve diaphragm type and piston are divided into two types, the same working principle, are based on the pressure difference between the upper and lower reaches of the power, pilot control, so that the diaphragm (piston) hydraulic differential operation, fully automatic adjustment by the hydraulic, so that the Lord Valve flap fully open or fully closed or in regulation. When the pressure water entering the control chamber above the diaphragm (piston) is vented to the atmosphere or the lower pressure zone downstream, the pressure acting on the lower part of the valve flap and under the diaphragm is greater than the pressure value above, pushing the main valve flap fully Opening position: The main valve flap is adjusted when the pressure in the control chamber above the diaphragm (piston) is in the middle of the inlet pressure and the outlet, and its position of adjustment depends on the combination of needle and pilot in the catheter system Control effect. The pilot valve can open or close its own small valve port by changing the pressure downstream so as to change the pressure value of the control chamber above the diaphragm (piston) and control the adjustment position of the main valve flap. Can be used for domestic water supply, fire protection system and industrial water supply system. Parts of main valve parts are as follows: Parts Name Material Body, bonnet Cast iron, cast steel, stainless steel Seat Tin bronze, stainless steel Clamp carbon steel, stainless steel + nitrile rubber Stem Aluminum steel, chrome stainless steel Membrane Nitrile Rubber diaphragm plate carbon steel, stainless steel spring stainless steel
