Abstract

The invention discloses a ball valve with small friction force. The ball valve comprises a main body, a wrench, a transmission shaft and a ball body, wherein sealing structures are fixed to the two sides of the interior of the main body respectively, a fixing groove is formed in the bottom end of the interior of the ball body, a bearing is fixed to the bottom end of the interior of the main body, a protection shaft is movably connected to the interior of the bearing, the wrench is installed outside the top end of the transmission shaft, and a dismounting structure is arranged at the top end of the wrench. By arranging a protection structure, friction force during switching is reduced, during use, large friction force can be generated between the ball body and the main body, by arranging the protection structure, the ball valve can be optimized, during switching, the ball body rotates, the protection shaft is clamped and fixed to the ball body through the fixing groove, the ball body rotates to drive the protection shaft to rotate, and the bearing supports the rotation of the protection shaft, so that the friction force is smaller when the ball body rotates, and the use convenience is improved.

Description

technical field [0001] The invention relates to the technical field of ball valves, in particular to a ball valve with small frictional force. Background technique [0002] The ball valve is a valve that can flexibly control the confluence, diversion, and switching of the flow direction of the medium in the pipeline and control the on-off of the pipeline. The ball valve has the advantages of good sealing, wear resistance, and long service life. It is mostly used in daily life. Control water flow or It is gas, but the traditional ball valve is difficult to move, and the user experience is poor, so a special ball valve with low friction will be used; [0003] However, when the existing ball valves on the market are used, the frictional force is relatively large, and the use is relatively laborious, so a ball valve with small frictional force is now developed to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a b...
