Description

Technical Field

[0001] The invention relates to the technical field of valve equipment, in particular to a self-cleaning ball valve. Background Art

[0002] A ball valve is a valve whose opening and closing part (ball) is driven by a valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. The ball valve includes a ball valve body, a ball and a valve stem for controlling the rotation of the ball, and a handle for controlling the rotation of the valve stem. In actual use, the handle applies a certain torque to the upper end of the valve stem and transmits it to the ball, causing it to rotate 90 degrees. The through hole of the ball coincides with or is perpendicular to the center of the channel of the ball valve body, achieving a fully open or fully closed action.

[0003] The ball valve in the prior art still has certain shortcomings: Most of the existing ball valves do not have a leakage warning function. When the two ends of the ball valve are connected to the connecting pipe to transport the fluid medium, the connection between the ball valve and the connecting pipe will loosen after long-term use, causing the fluid medium to leak. The ball valve itself does not have a leakage warning function, so it cannot remind the staff, and it is not easy to seal the leakage, which leads to the continuous loss of the fluid medium, thereby reducing the maintenance efficiency of the staff; The ball valve has only the most basic opening and closing function and structure, and its function is single. It is exposed to the outside, so when it falls accidentally, it will directly contact the ground and cause damage, and it does not have a certain protective effect; And it does not have a certain cleaning function. After long-term use, the inner wall of the ball valve will absorb dirt. The ball valve only has the function of cleaning the gap between the valve core and the sealing ring, but it is not convenient to clean the inner wall of the ball valve body close to the connecting pipe, which will affect the flow and quality of the liquid and is inconvenient to use; Therefore, it is necessary to design a ball valve with self-warning, self-protection and self-cleaning functions to solve the above problems.

At the same time, with the cooperation of the inclined baffle 705 and the inclined discharge channel 713, the liquid can be prevented from scouring the rotating shaft 704, thereby preventing the corrosion of the rotating shaft 704 and extending the service life of the rotating shaft 704. When the liquid does not circulate, the liquid between the fixed sleeve 701 and the supporting sleeve 702 can be discharged through the inclined discharge channel 713, thereby effectively improving the convenience of cleaning; In addition, the protective mechanism 10 is used in conjunction to prevent the ball valve body 1 from accidentally falling off and directly onto the ground, thereby damaging the ball valve body 1. With the cooperation of the tension spring 1002, the arc plate 1003, the connecting rod 1005 and the sponge sleeve 1006, a buffering protection effect can be achieved, so that the ball valve body 1 can self-warn, self-clean and self-protect, which effectively enhances the practicability and functionality of the ball valve body 1 and extends the service life of the ball valve body 1.
