AI Technical Summary

Technical Problem

During the use of existing ball valves, due to wear of seal rings and changes in temperature and pressure, the sealing performance may decline, leakage may occur, and impurities in the water cannot be effectively filtered, resulting in wear of the ball valve and damage to downstream equipment.

Method used

A ball valve driving automatic compensation function is designed, and the first spring automatically compensates for wear of the sealing ring to ensure sealing performance; at the same time, a filter mechanism is integrated, including a first filter mesh and a storage tank, and impurities are collected through centrifugal force to prevent impurities from entering the downstream equipment.

Benefits of technology

Through the automatic compensation function of the first spring, the sealing performance of the ball valve is maintained and the service life is extended. The filtering mechanism effectively filters impurities in the water, prevents equipment wear and leakage, and improves the stability and reliability of the system.

Abstract

The invention discloses a ball valve with a driving automatic compensation function, and relates to the technical field of ball valves, the ball valve comprises a filtering mechanism, the bottom of the filtering mechanism fixedly communicates with a liquid leakage monitoring mechanism, and the top of the filtering mechanism is fixedly connected with a driving mechanism; the filtering mechanism comprises a first valve body. According to the valve, the first spring can automatically stretch and compensate a gap when the sealing ring is abraded, the sealing performance of the valve is recovered and kept, the stability and reliability of a production system are ensured, and when the valve is used, the first filter screen can effectively filter impurities in water and prevent the impurities from blocking or corroding pipelines and equipment; water flow drives the cleaning brush to rotate through the rotating blade, impurities accumulated on the surface of the first filter screen are brushed off, then the impurities are thrown into the storage tank under the action of centrifugal force and collected in a centralized mode, the arc-shaped second filter screen is designed in the storage tank, a narrow channel is formed, the arc-shaped second filter screen is matched with the baffle, and therefore impurity leakage can be effectively prevented; and the pipeline is blocked due to the accumulation in front of the first filter screen.
