Abstract

The invention discloses a vacuum pipe clamp valve applied to a vacuum system and a control method of the vacuum pipe clamp valve. The vacuum pipe clamp valve comprises a clamp valve pipe body and a casing pipe. A seal space is formed between the inner wall of the clamp valve pipe body and the outer wall of the casing pipe. A first elastic pressing block device and a second elastic pressing block device are arranged at the outer side of the clamp valve pipe body. A pressing block of the first elastic pressing block device and a pressing block of the second elastic pressing block device extend into the seal space, and the casing pipe is clamped and closed through the pressing block in the first elastic pressing block device and the pressing block in the second elastic pressing block device.A vacuum pipe interface is further arranged at the outer side of the clamp valve pipe body, wherein the vacuum pipe interface is used for conducting vacuum extraction on the seal space. After the sealspace is extracted to be in the vacuum state through the vacuum pipe interface, the pressing block of the first elastic pressing block device and the pressing block of the second elastic pressing block device retract to loosen clamping of the casing pipe, so that the casing pipe is opened. By means of the vacuum pipe clamp valve, it is not needed to additionally arrange an air compression systemto control the pipe clamp valve to be switched on and off; production cost is lowered; and reliability is high.

Description

Technical field [0001] The invention relates to a pipe clamp valve and a control method thereof, in particular to a vacuum pipe clamp valve applied to a vacuum system and a control method thereof. Background technique [0002] The pinch valve is also called the pinch valve, air bag valve, pinch-off valve, etc. in China. It uses pneumatic, electric, manual or hydraulic driving methods to squeeze the casing to switch or adjust. The pinch valve has a wide range of uses and can be used in many fields such as paper mills, pulp mills, electronics industry, food industry, cement, sand, glass and industrial sewage treatment plants. [0003] Among them, the pneumatic pinch valve is a new type of valve improved on the basis of the manual pinch valve in order to meet the special requirements of customers. It consists of upper and lower cast iron, cast steel valve bodies, rubber sleeves, large and small valve stems, gates, upper and lower guide posts, Pneumatic device and other parts. [0004]...
