The description and characteristics of blade type gate valve
Blade type gate valve, also called the knife gate valve,suitable for pulp with suspended particles, fiber, ash, coal slurry, cement mixture medium pipeline, on the blade shape ram can use the fiber cutter cut off the medium. Chamber body actually does not exist, ram in side guide groove inside the elevator, and from the bottom of the lugs compression on the seat, if you need to achieve high sealing medium, o-type sealing seat can be used to realize two-way sealing. According to the drive mode, it can be divided into manual type knife gate valve, pneumatic knife gate valve, electric knife gate valve.
Type knife gate valve has light,flexible operation, small volume, smooth channel, small flow resistance, light weight, easy to install, easy to remove, nominal size (~ DN800, can in the work pressure 0.6 MPa to 1.6 MPa, the using temperature is 100 ¡æ or less can do the normal work. Blade type gate valve its ram has shear function, it can shave their sticky substance on the surface of the seal, automatic removal of impurities. Stainless steel gate to prevent seal leakage caused by corrosion.
Product features of the blade type gate valve:
1. Short structure length, material saving, which can make the pipeline system greatly reduce the overall weight.
2. Small effective occupied space, which can effectively support the pipeline strength and reduce the possibility of pipeline vibration.
3. Choose austenitic stainless steel gate,greatly improves the decay resistance performance, which can effectively prevent disc corrosion and lead to seal leakage.
4. Using the flexible PTFE packing material, reliable seal, flexible and light operation.
5. The damper has the blade function, which can effectively brake the circuit medium of various kinds of sundry.
