Abstract
The invention discloses a tube pinch valve. The tube pinch valve comprises a box body, an eccentric wheel, a power transmission mechanism, at least one hose and at least one hose squeezing mechanism. A driving shaft is arranged on the eccentric wheel. The power transmission mechanism is in transmission connection with the eccentric wheel so that the power transmission mechanism can drive the eccentric wheel to rotate, and the driving shaft can be made to do circling motion. The hoses penetrate through the box body. The hose squeezing mechanisms are in one-to-one correspondence with the hoses. Each hose squeezing mechanism comprises an ejection hammer and a connecting rod, and the ejection hammer is assembled in the box body is a sliding mode. One end of each connecting rod is hinged to the driving shaft, and the other end of each connecting rod is hinged to the corresponding ejection hammer. The ejection hammers are matched with the hoses in a squeezed mode. When the power transmission mechanism operates to make the ejection hammers press the hoses, the interiors of the hoses are in a closed state. When the power transmission mechanism operates to make the ejection hammers keep away from the hoses, the interiors of the hoses are in an open state. The tube pinch valve can be prevented from being in contact with liquid and being corroded, and the service life of the tube pinch valve is greatly prolonged; in addition, the tube pinch valve is suitable for conveying various kinds of liquid, thereby having multiple purposes.
