The structural design of eccentric hemisphere valve is as follows:
1. The upper and lower shaft ends of the eccentric hemisphere valve shall be equipped with at least two O-rings to ensure that the ball valve is free from leakage.
2. The eccentric hemisphere valve has sufficient strength, and the eccentric crankshaft adopts a fixed ball structure, without any vibration at high flow rate.
3. In order to ensure the smooth flow passage of eccentric hemisphere valve, the ball adopts a semicircular passage, which has good liquidity and linear adjustment performance. It is not easy to accumulate dirt in the valve chamber.
4. The eccentric hemisphere valve is composed of valve body, eccentric shaft, valve cover, ball crown, shaft sleeve, valve seat and other parts. The valve can be opened and closed by rotating the eccentric shaft 90 ° to cut off the medium.
5. The eccentric hemisphere valve adopts a top mounted structure, so it is not necessary to remove it from the pipeline during maintenance, just remove the bolts on the valve cover, remove the valve cover, and then take out the eccentric shaft, which improves the convenience of maintenance.
