[0002] Ball valve is usually used for the adjustment and control of fluid, and is generally installed horizontally in a pipeline. According to the driving mode, the ball valve is divided into a pneumatic ball valve, an electric ball valve and a manual ball valve.

[0003] In the above-mentioned manual ball valve, the closing and flow of the ball valve are completed by rotating the ball body opening and closing member. The rotation of the ball body opening and closing member is realized by rotating the handle connected to the ball body opening and closing member by hand. In the structure, in the use process, in order to maintain the rotatable space of the ball body opening and closing member and the handle, a rotation gap is left between the handle and the cylinder of the ball valve, and between the ball body opening and closing member and the cylinder of the ball valve. The rotation gap is generally in an open state due to the setting of the handle, so that the ball valve often becomes a leakage point in the process of pipeline fluid transportation, and the sealing performance is low.

Since the cap is arranged on the top of the valve rod sleeve, the sealing performance of the valve rod can be effectively guaranteed in the unadjusted state, and the condition that the ball valve becomes a leakage point is effectively avoided. Moreover, the valve rod sleeve is welded with the cylinder to have higher overall sealing performance.

[0007] Further, a rotating handle is detachably connected to the valve rod.

[0008] In the above technical solution, the rotating handle is detachably connected to the valve rod. When the valve body needs to be adjusted, the cap is detached, and then the rotating handle is inserted into the valve rod sleeve to be connected with the valve rod to adjust the rotation of the ball body opening and closing member. After the adjustment is completed, the rotating handle is detached, and the cap is installed on the valve rod sleeve to guarantee the sealing performance.

[0009] Further, the end cover of the barrel end is provided with an external connection part.

[0010] Further, the end cover is provided with a sealing ring at the connection with the barrel.

[0011] Further, the ball opening and closing member is provided with a wear-resistant layer.

[0012] In the above technical solution, the wear-resistant layer can effectively increase the service life of the ball opening and closing member.

[0013] Further, the valve rod sleeve is welded on the side wall of the barrel.

[0014] Further, the outer wall of the plug cap is provided with an edge.

[0015] In the above technical solution, the edge facilitates force application for disassembling the plug cap.

[0016] Further, the end cover is fastened on both ends of the barrel.

[0017] Compared with the prior art, the high sealing ball valve has the advantages that the overall structure is simple and reasonable, and the flexibility and applicability after assembly are high, the valve rod sleeve is arranged on the part of the valve rod of the ball valve in the barrel, and the plug cap is used for plugging, so that the ball valve is effectively avoided from becoming a liquid leakage point of the pipeline, thereby reducing resource loss caused by liquid leakage.
