Aperture-adjustable self-cleaning ball valve and using method thereof

Abstract

The invention relates to the technical field of ball valves, in particular to an aperture-adjustable self-cleaning ball valve and a using method thereof. The ball valve comprises a valve pipe fitting. The left end of the valve pipe fitting is in threaded connection with a first external connection threaded part, the right end of the valve pipe fitting is in threaded connection with a second external connection threaded part, an inner cavity of the second external connection threaded part is provided with an inner concave annular cavity in a prediction manner, and an aperture regulator is arranged in the inner concave annular cavity in a sleeved manner. When water flow passes through a rotating device and the shaft end of the rotating device rotates, a semicircular cover can rotate in a driving cavity, when the semicircular cover rotates, a ball in the semicircular cover is arranged in a spiral groove in a sleeved manner and rotates in the spiral groove, a universal ball rotates, a shaft rod gear on a shaft rod plate drives an annular gear sleeve to rotate at the moment, an arc-shaped cover rotates at the moment, an arc-shaped scraping blade on the rotating arc-shaped cover scrapes impurities on the ball valve, the impurities enter the surface of the arc-shaped cover through a notch to be accumulated, water flow is pushed for driving, internal impurities and rust can be automatically scraped, manual cleaning operation is not needed, and the linkage performance and the mechanical function are high.

Description

technical field [0001] The invention relates to the technical field of ball valves, in particular to a self-cleaning ball valve with adjustable aperture and a use method thereof. Background technique [0002] The ball valve is a valve whose opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. Ball valves are divided into pneumatic ball valves, electric ball valves, and manual ball valves according to the driving method. In China, ball valves are widely used in petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electric power, municipal, steel and other industries.

Problems solved by technology

[0003] Since water flows through the inner diameter of the valve, when the water flows through the inner diameter of the ball valve, the water flow cleans the inner diameter of the ball valve relatively cleanly, but when the liquid with residues on the contact surface between the outer wall of the ball valve and the inner wall of the valve tube is intercepted, the residues in the liquid will deposit and stay in the There is accumulation on the surface and bottom gap of the ball valve, but some existing ball valves on the market cannot automatically clean this part of the residue, causing it to gradually solidify and accumulate over time. Large and water leakage problems, so it is very troublesome to disassemble the whole when repairing
