type knife gate valve has the advantages of 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 valve, flat gate valve, globe valve, regulating Industrial Valves, butterfly valve, ball Industrial Valves valve, such as the weight of the big, big flow resistance, the area is large, difficult problems, such as installation, can replace the cut-off valve and control valve, can work in pressure 1. 0MPa- 2. - 5 mpa, the use of temperature 29 - 550 ℃ cases normal work. Type knife gate valve disc shear function, can shave their sticky substance on the surface of the seal, automatic removing debris, stainless steel gate to prevent seal leakage caused by corrosion. Type knife gate valve 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 body, durable and body reinforcement design to improve body strength, double-headed screw using the open/close more quickly. 4. Whole stainless steel material, can prevent the corrosion damage. Body and stuffing box for precision casting, of which the body USES the 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. Body type knife gate Industrial Valves guide block ram right movement. Extrusion block ram ensure effective seal. 10. Type knife gate valve can be arbitrarily choose driving mechanism. 11. V gate can be used as a control 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. plate with 5 points, make the valve plate has good from to. When the valve is closed, and back pressure, the valve plate is not skewed.
