This valve is an electric drive mode. It has two independent property rights technologies. It has the advantages of smooth operation, small impact vibration, reliable use, good sealing performance and long service life. It is mainly used in military industry and other fields. The valve is powered by a three-phase asynchronous motor or a variable frequency motor, and is connected with the speed reducer. The output shaft of the reduction gear box is connected with the screw rod through the coupling, and the driving body moves along the axial direction, and the driving body is connected with the valve plate through the swing rod. Thereby the valve opening and closing action is achieved.
The support structure is evenly distributed by using multiple swing bars, and the valve has small impact vibration and low noise;
The reverse belt supports the moving mechanism to achieve sealing under reverse pressure;
The dynamic seal is sealed with a star-shaped fluorine rubber ring, which has a small air leakage rate and reliable sealing;
The valve body is internally welded and the leakage rate is small.
Frequency conversion braking technology, good braking effect, small impact
