Abstract

The invention discloses a sealed leakproof ball valve which comprises an outer shell of the ball valve, a ball-shaped core, a driving lever and a support rod. The ball-shaped core is arranged in the outer shell of the ball valve, the liquid outlet end of the outer shell of the ball valve is provided with a first seal ring and a second seal ring, the liquid inlet end of the outer shell of the ball valve is provided with a fourth seal ring, a ring of groove is formed in the liquid inlet of the outer shell of the ball valve, a fifth seal ring is arranged between the ball-shaped core and the liquid inlet of the outer shell of the ball valve, and a stair check ring used for fixing the fifth seal ring is arranged in the liquid inlet of the outer shell of the ball valve; a first bearing is arranged on the driving lever in a sleeving mode. In this way, the sealed leakproof ball valve utilizes the multiple seal rings to improve the leakproofness, the capacity of liquid shock resistance is strong, the leakage of mediums in the use process is avoided, and the safety is high.

Description

technical field [0001] The invention relates to the field of valve design, in particular to a sealed and anti-leakage ball valve. Background technique [0002] Ball valve is a widely used valve, its main features are compact structure, high reliability, easy operation and maintenance, suitable for general working media such as water, solvent and natural gas, and also suitable for media with harsh working conditions, suitable as On-off or cut-off valves are used. [0003] The pressure in some pipelines is high, and the ball valve is prone to leakage due to sealing problems, polluting the environment, reducing the transportation capacity of the pipeline, and even causing poisoning or explosion accidents, causing large economic losses. Contents of the invention [0004] The main technical problem to be solved by the present invention is to provide a sealed and anti-leakage ball valve, which improves the sealing performance and pressure bearing capacity of the ball valve and ...
