Automatic packing pressure control slow closing butterfly valve structure features

Automatic pressure control liquid-controlled slow-closing butterfly valve is currently used for turbine inlet of the key control equipment, has a good seal, adjust the performance and create a unique three-eccentric structure of the basic structure of the hydraulic butterfly valve, auto insurance Pressure liquid control slow closing butterfly valve by the field application, the operating system is running well, in addition to the butterfly valve has the advantages of three eccentric structure also has the following obvious advantages and characteristics.

Automatic pressure control slow closing butterfly valve drive system for the same pressure two drive device, the device is small and the butterfly valve opening and closing speed of the control range, the initial opening of the high pressure small flow control, so that the butterfly valve open instantaneous state Smooth, no violent fluctuations, completely eliminate the water hammer within the system hidden dangers, and then cut into the faster turning angular velocity, the cylinder will set the desired thrust and speed will be smooth butterfly open.

Automatic packing pressure control slow closing butterfly valve installation position is usually horizontal and horizontal, disc deviation from the position of a reasonable placement can make full use of the pipe within the dynamic hydraulic torque drive butterfly valve closed smoothly, the valve installation The position will show the joint effect of Moment of Moment and Hammer Moment. With the gradual completion of the turn-off corner, the Moment of Momentum will tend to decrease, and the Moment of Moment will make the Moment of Moment close and slow to become slow and steady, thus strictly eliminating water Hammer phenomenon, zero leakage of the sealing effect will be in this reasonable and tight control system can be reliably achieved.

Automatic pressure control slow closing butterfly valve back to the electro-hydraulic control system with remote control function, the disc at any speed on and off as well as any position of the lock can be designed through a variety of hydraulic control valve easily achieved.

Automatic dwell pressure control slow closing butterfly valve with a manual pump, the system can still normally shut down or open the butterfly valve when the power for some reason.
