DX7K41X type storage tank type hydraulic control slow-closing check butterfly valve is the key control equipment used at the inlet of hydraulic turbine at present. It has good sealing and regulating performance. This valve is a new product developed by Qigao valve in recent years. Through careful investigation and Research on many similar products at home and abroad, it creates a unique Three-eccentricity valve. For the basic structure of the hydraulic butterfly valve, after field application, the operating system runs well, the butterfly valve in addition to the advantages of the three eccentric structure has the following obvious advantages and characteristics.


main features


1. The driving system of this valve is a two-stage driving device with the same pressure. The volume of this device is small and the opening and closing speed of the butterfly valve is wide. The initial opening section is controlled by high pressure and small flow rate. The instantaneous state of the butterfly valve opening is smooth and there is no violent fluctuation. The hidden danger of water hammer in the system is completely eliminated. Then, the turning angle speed of the butterfly valve is cut into relatively fast and the hydraulic pressure is controlled. The cylinder will be smoothly opened with the set of ideal thrust and speed.


2. The installation position of the butterfly valve is usually transverse horizontal. The proper placement of the deviation position of the butterfly plate can make the butterfly plate close smoothly by making full use of the hydrodynamic torque in the pipeline. The installation position of the valve will reflect the effect of the interaction between the hydrodynamic torque and the weight torque. As the closing angle is gradually completed, the hydrodynamic torque will tend to be the same. As a result, the zero leakage sealing effect will be reliably realized in this reasonably rigorous control system.


3. The electro-hydraulic control system of this valve has remote control function. The opening and closing of butterfly plate at any speed and the locking at any position can be easily realized by various kinds of hydraulic control valves with reasonable design.


4, the valve is equipped with manual oil pump, the system can shut down or open the butterfly valve normally because of power failure.
