Introduce the composition and using skill of plunger dispens

writer:点胶设备 time:2019-10-26 10:37 clicks:
The plunger type dispensing valve is composed of rubber cylinder, valve cover, valve rod, cylindrical axis, hole frame, sealing ring, handle and other parts. When combined with the dispensing controller, the valve rod is used to push the cylindrical axis to move left and right repeatedly in the middle of the hole frame to open and close the gate valve. The transition fit is selected between the cylindrical axis and the sealing ring in the valve, and the flange plate screw in the screw cap is adjusted to make the side force caused by the reduction of the sealing ring and the tightness of the hole surface and the outer circle of the plug in the rubber cylinder, so as to ensure the tightness of the sealing ring. The airtightness of the gate valve avoids internal and external leakage. In addition, the opening torque of the gate valve is small, and the gate valve can be opened and closed quickly.

The plunger valve can be installed at any place. See the upward arrow of the rubber cylinder for the material flow direction.
 
After using for a period of time, if the sealing ring is worn out and has glue leakage, it is necessary to turn off the gate valve first, and then tighten the screws of the middle flange plate evenly and slightly so that there is no glue leakage in the glue valve.

Notes on disassembly of plunger dispensing valve
 
It is not suitable to tighten the screws too tightly. In addition, the cracks and gouges on the cylinder axis and the surface of the new seal ring shall be avoided during the removal and replacement.
 
Because the surface of cylinder axis is processed by high precision grinding machine. The sealing ring is a new non-toxic rubber seal with strong ductility and high wear resistance, so it is reliable and durable. Furthermore, the service life of the plunger valve is improved.
