Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a convenient and easily dismantled ball valve. Background Art

[0002] Valves are pipe accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems, and have functions such as shutoff, regulation, diversion, prevention of backflow, pressure stabilization, diversion, or overflow pressure relief. Ball valves are a common fluid control valve, and their working principle is to control the on and off of the fluid by rotating the ball.

[0003] Usually, ball valves are most suitable for direct opening and closing. The ball valve itself has a compact structure. When the ball valve starting device is stuck at a certain angle, the drive device cannot start the ball assembly normally, and the ball valve components need to be manually disassembled for maintenance, which is more troublesome. In addition, the existing ball valve has an integral structure inside, which is more difficult to disassemble and assemble. When the ball is damaged, it is not convenient to remove it from the inside of the valve body.

[0004] Therefore, those skilled in the art provide a convenient and easily dismantled ball valve to solve the problems raised in the above background technology. Utility Model Content
