Working principle of lever extrusion electric pipe clamp valve

Lever extrusion electric pipe clamp valve, also known as electronic electric pipe clamp valve, is a special valve that uses the flexibility of natural rubber as a moving part to achieve flexible closing. It is mainly used in the transmission pipeline of liquid-solid mixture and gas-solid mixture to replace the functions that are difficult to achieve with general valves such as ball valves and gate valves. The pinch valve shall be used in mining, metallurgy, chemical industry, medicine, cement, ceramics, glass, plastics, food and beverage, animal husbandry, wine making, municipal water affairs and other fields, such as ore washing device, powder spraying system, train vacuum stool collection system, vacuum conveying system, feed conveying system, urban rain and sewage diversion system, etc.

The electronic electric pipe clamp valve is a lever extrusion type, automatic control motor system driven, flange connected pipe clamp valve. The servo motor or stepper motor drives the upper and lower clamping crossbars to squeeze the inner bushing, so that the inner bushing is clamped and the valve is closed; When the motor reverses, the inner bushing opens and the valve is smooth. Precise control of valve opening can be realized by precise control of motor through computer system.

Operating principle of lever extrusion electric pipe clamp valve:

Electronic electric pipe clamp valve and electronic electric pipe clamp valve belong to lever extrusion type. The two ends of the inner rubber bushing inside the valve are connected with the pipeline and become part of the material conveying pipeline. The two sides of the middle part of the inner bushing are equipped with extrusion levers. When the upper and lower levers are squeezed together, the pipe clamping valve is compressed to close the channel; The channel opens after the lever is released. The extrusion lever can be driven by manpower (the hand wheel drives the screw), compressed air (cylinder), and electricity (electric actuator) to realize the extrusion action. The lever extrusion type pinch valve is characterized by that it is easy to realize forced closing for applications with high pipeline pressure; The clamping valve can be closed by force self-locking under accident conditions (gas and power failure) through additional devices; The valve opening is controlled by pneumatic positioner; Accurate flow control is achieved through electric actuators.

Pipe clamp valve application:

Fully open: the full bore elastic valve sleeve of the pipe clamp valve is free of any gap and dead angle.

During closing: the center line is closed, which avoids turbulence and wear in the casing. The valve sleeve becomes a smooth closed venturi, which can be self-cleaning in each operation.

Close: When the pipe clamp valve is fully closed, it ensures two-way zero leakage closing, and adopts the internal safety design that requires maintenance without sealing elements.
