Abstract

The invention relates to an integrated servo electric pinch valve which comprises a valve body, a pressing head, a lead screw, a motor, a magnetic encoder and a driver. The valve body is connected with the motor; the motor is connected with the driver; a fixed baffle strip is arranged in the valve body; the pressing head is slidably connected with the valve body. The lead screw is connected with the pressing head. The screw rod is connected with the motor; and the motor is connected with the magnetic encoder. The driver has various interfaces and control modes, and can control a position loop, a speed loop and a current loop in real time to form a closed loop. The driver can adjust the clamping force by controlling the current, and the internal pressure of the hose can be calculated by reading the real-time current. When the driver receives a switch signal or a bus control signal, the control motor rotates to drive the lead screw and the pressing head to reciprocate in the cavity of the valve body, a gap with the adjustable size is formed between the pressing head and the blocking strip, the hose is pressed in the gap, and therefore the hose can be loosened and clamped, and the clamping force is adjustable.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an integrated servo electric pinch valve. Background technique [0002] The main function of the pinch valve is to open or close the pipeline by pinching the hose. The pinch valve body does not come into contact with the medium in use, which can ensure that the liquid or gas passing through is not polluted, and can keep the pinch valve clean. Therefore, it is widely used in bioengineering, food industry, dosage systems, blood processing / analysis, laboratory analysis and other equipment. [0003] At present, the existing pinch valves are mainly pneumatic and electromagnetic. The control method is open-loop switch control, once the water is cut off, it will be out of control. Secondly, the clamping force is small, the clamping force cannot be adjusted, and it cannot cope with large-diameter hoses in industrial production, and one valve body can only cope with one pipe diameter. ...
