Ball valve with blockage cleaning function

Abstract

The invention discloses a ball valve with a blockage clearing function. The ball valve comprises a connecting flange, a connecting plate, a first valve body, a second valve body, a bearing, a ball body and a side plate; a motor is fixedly connected to the top end of the first valve body; the top end of a mounting plate is fixedly connected with the inner wall of the first valve body; a connectingshaft is arranged in the mounting plate; the top end of the connecting shaft is fixedly connected with the tail end of an output shaft of the motor; the bottom end of the connecting shaft sleeves bevel gears; a first shaft body is arranged on one side of the mounting plate; the left end of the first shaft body is rotationally connected with the side face of the mounting plate through the bearing;the left end of the first shaft body penetrates into the mounting plate; the left end of the first shaft body sleeves with the bevel gears; and the two bevel gears are connected in an engaged mode. Acorrugated pipe has a telescopic function, the overall length of the ball valve can be adjusted by pulling the corrugated pipe at the moment, meanwhile, threaded rods slide along the side plate, a first spring is compressed, then fastening nuts are screwed down, and the second valve body and the corrugated pipe can be fixed.

Description

technical field [0001] The invention relates to a ball valve, in particular to a ball valve with the function of cleaning blockages. 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 adjustment 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. [0003] The internal structure of the traditional ball valve is simple, and it is not easy to clean when it is blocked during use. It needs to be disassembled as a whole, which is troublesome to operate. Moreover, the current ball valve is not easy to adjust according to the demand during ins...

Problems solved by technology

[0003] The internal structure of the traditional ball valve is simple, and it is not easy to clean when it is blocked during use. It needs to be disassembled as a whole, which is troublesome to operate. Moreover, the current ball valve is not easy to adjust according to the demand during installation, and lacks a certain length compensation. ability
