Aluminum alloy pinch valve, also known as aluminum alloy pinch valve, aluminum alloy hose valve, consists of left and right aluminum alloy valve bodies, rubber tube sleeves, large and small valve stems, upper and lower gates, guide posts and other parts.
Wear-resisting, anti-corrosion, anti-freezing, good sealing performance, just need to replace the rubber sleeve, it is as good as new, the valve body can be used, and the service life is 4-6 times that of ordinary valves. There are many ways of driving, such as manual, pneumatic, electric and so on.
When the handwheel is turned in the same direction, the large and small valve rods drive the upper and lower gates at the same time, compress the sleeve, and close, and then reverse to open, so that the gate reciprocates up and down between the guide posts to complete the valve opening and closing work. In addition, due to the bearing capacity of the rubber sleeve, when switching, if the operator feels a moderate amount of resistance when rotating the handwheel, it has reached the opening and closing limit.
