Description
Technical Field

Background
The pinch valve is also called a pinch valve and a pinch valve, and is a mechanism for realizing on-off of liquid in a pipeline by clamping and releasing a hose. Pinch valves are suitable for situations where the medium being transported needs to be completely isolated from any internal valve components, such as for example, the transport of blood products, concentration, washing, etc., where pinch valves are used in large numbers with which to control the transport of blood products. Pinch valves are classified as pneumatic, electric, hydraulic or electromagnetic pinch valves according to the driving mode, and a sleeve (hose) is an important part of the pinch valve.
The clamping force is different for hoses of different materials, wall thicknesses and hardness. The current electromagnetic pinch valves on the market mainly realize the adjustment of the hose clamping force by adjusting the number of coils and the return spring, and require very specialized knowledge, thus basically belonging to custom services. Moreover, the clamping force of the pinch valve is smaller, and the pinch valve is only suitable for hoses with lower hardness and thicker tube walls. If the electromagnetic pinch valve with large clamping force is customized, the problems of serious heat generation and high noise are difficult to avoid. In addition, if custom pinch valves are used, the hose provided by the pinch valve manufacturer needs to be purchased, not only with fewer options, but also with a significant increase in cost.
