Description
Technical Field
The utility model relates to a valve field, in particular to three formula ball valves convenient to dismantle and lock.
Background
The three-piece ball valve and gate valve are both of the same type, except that the closing member is a sphere which rotates around the central line of the valve body to open and close. Ball valves are used in pipelines primarily to shut off, distribute and change the direction of flow of media. The three-piece ball valve can be closed tightly only by rotating 90 degrees and a small rotating moment. The completely equal inner cavity of the valve body provides a straight flow passage with small resistance for the medium. The ball valve has the main characteristics of compact structure, easy operation and maintenance, suitability for common working media such as water, solvents, acid, natural gas and the like, and has certain unique advantages of the structure, such as no friction of a switch, difficult abrasion of sealing and small opening and closing moment.
However, in the existing three-piece ball valve, the left end cover and the right end cover are tightened on the valve body through bolts, so that tools such as a wrench are required during installation, but half of the three-piece ball valve is short of corresponding tools in a family environment, and the three-piece ball valve is inconvenient to disassemble and assemble. In addition, the existing three-piece ball valve is used for screwing a handle of a valve rod, the handle cannot be well fixed after being rotated to a position, and the problem that the opening degree of a ball core is changed due to accidental deflection of the handle is easy to occur.
