Product name: hydraulic control slow closing check butterfly valve
Product features: automatic pressure maintaining hydraulic control slow close check valve, is the key to the currently used in turbine inlet control equipment, has a good seal, regulation performance, the valve is a new product developed by our company in recent years, through a variety of similar products at home and abroad for investigation and research of the serious, created the unique triple eccentric as basic structure of hydraulic control butterfly valve, through field application, the operating system running well, the butterfly valve not only have the advantages of three eccentric structure also has the following obvious advantages and characteristics. Automatic pressure control slow closing check butterfly valve, pressure control slow closing check butterfly valve, check butterfly valve.
1, this valve with pressure in drive systems for two levels of drive device, the device is small in size and butterfly valve opening and closing speed control range is big, small open period for high pressure flow control at the beginning of the butterfly valve opens instantaneous state flat, no volatile, eliminate water hammer hidden trouble in the system, then cut into faster rotation velocity, hydraulic cylinder set to an ideal open the butterfly plate steady thrust and speed.
2, the installation position of the butterfly valve is usually lateral horizontal, the placement of butterfly plate off position can make the butterfly plate making full use of the pipe hydrodynamic torque drive the smooth operation of the disc and close the valve installation position will reflect hydrodynamic torque and heavy hammer moment interaction effect, as the closed Angle gradually completed, hydrodynamic torque will be reduced, heavy hammer moment will make the closing moments of slow and steady, thus strictly to eliminate the occurrence of water hammer, zero leakage of the seal will be in the strict control system of the rational and reliable.
3. The electro-hydraulic control system of this valve has the function of remote control. The opening and closing of the butterfly plate at any speed and locking at any position can be easily realized by designing reasonable hydraulic control valves.4. This valve is equipped with a manual oil pump, which can be normally closed or opened in case of power failure.
