Type knife gate valve gate has simple and compact structure, reasonable design, lightweight materials, sealing is reliable, flexible and convenient operation, small volume, smooth channel, small flow resistance, light weight, easy to install, easy to remove, etc, thoroughly solved the common gate door, flat gate valve, globe valve, regulating valve, butterfly valve, ball valve gate valve door door the weight of the big, big flow resistance, the area is large, difficult problems, such as installation, can replace gm cut off valve and regulating valve, can work in pressure 1. 0MPa- 2. - 5 mpa, the use of temperature 29 - 550 ℃ cases normal work. Type knife gate valve door of the gate have shear function, can shave their seal adhesive on the surface of the object, automatically removing debris, stainless steel gate to prevent seal leakage caused by corrosion. Type knife gate valve door is suitable for mining coal in power plants, slag discharge, urban sewage treatment, food, paper making, medicine, petroleum, chemical industry such as oil, water, steam pipe road, connected or truncated slurry pipeline, gold mineral powder, sand, slag, coal slurry, pulp, wood pulp, tailings, fibers, dust, chemical sewage, sedimentation tank, asphalt, the export of silo, fruits, cereals, abattoir wastewater, etc. 1. Can promote the disc sealing surface, can shave their sticky on the surface of the sealing, automatic removal of impurities. 2. Can prevent seal leakage caused by corrosion of stainless steel gate, fine grinding and polishing processing can obtain better sealing effect. Knife plate bottom into the blade shape processing of soft materials such as fiber, paper pulp, wood pulp has cut off function, at the same time has good opening and closing action. In the upper blade equipped with hard teflon wiper, can prevent the dust and scratch sexual material such as gravel into the stuffing box, can significantly improve the blade life. 3. The stainless steel valve body, durable and valve body reinforcement design to improve the valve body strength, double-headed screw using the open/close more quickly. 4. Whole stainless steel material, can prevent the corrosion damage. The valve body, the stuffing box for precision casting, in which the valve body adopts integral casting flange type, material can be selected according to user needs 304, 316, 316 l, WCB, 2 crl3, sealing ring using PTFE reinforced PTFE material, corrosion resistance, wear resistance, non-stick slag. 5. All round the dc channel design of sludge, BuKa resistance. 6. Seal packing design on science, make the seal is safe and effective, durable. 7. Short length structure, can save raw materials and installation space, also effectively support the strength of pipeline. 8. Triangular support save raw materials, to guarantee the need of mechanical properties. 9. Type knife gate valve gate valve body on the guide block ram right movement. Extrusion block ram ensure effective seal. 10. Type knife gate valve door still can choose driving mechanism. 11. V gate can be used as a regulating valve. 12. Compact design, occupying small space, light weight, cheap, easy to install, wear-resisting prevent measures to perfect, easy maintenance, easy to use and long service life, and can choose which drives. 13. The valve plate with 5 points, make the valve plate has good from to. When the valve is closed the door and back pressure, the valve plate without deviation.
