Knife gate valve has a number of typical features
The knife gate valve has the advantages of simple and compact structure, reasonable design, light material saving, reliable sealing, light and flexible operation, small volume, smooth passage, small flow resistance, light weight, easy installation, and easy disassembly.
Valves, flat gate valves, globe valves, regulating valves, butterfly valves, ball valves, etc. Valves are heavy, have large flow resistance, large area, and difficult installation. They can replace general shut-off valves and regulating valves. They can work under pressure 1.0MPa-2.5. MPa
, Working temperature -29-550 °C normal work. The gate of the knife gate valve has a cutting function, which can scrape off the adhesive on the sealing surface and automatically remove the impurities. The stainless steel gate plate can prevent the seal leakage caused by corrosion.
Knife gate valve is suitable for coal preparation, slag discharge, urban sewage treatment, food, paper, medicine, petroleum, chemical and other oil products, water and steam pipelines of mine power plants. It is used to connect or cut cement slurry and gold in pipelines. Powder, ore,
Slag, slime, pulp, wood pulp, tailings, fiber, dust, chemicals, sewage, sedimentation tanks, asphalt, silo exports, fruit, grain, slaughterhouse wastewater and other media.
1. It can lift the sealing surface of the gate, scrape off the adhesive on the sealing surface, and automatically remove the impurities.
2. The stainless steel gate plate can prevent the seal leakage caused by corrosion, and the fine grinding and polishing treatment can obtain a better sealing effect. The bottom of the blade is machined into a blade shape, which has the function of cutting off the soft materials such as fiber, pulp and wood pulp, and has a good opening and closing effect.
3. The stainless steel valve body is durable and durable. The valve body reinforcement design improves the strength of the valve body. The double-headed screw can be opened and closed more quickly.
4. The overall stainless steel material prevents corrosion damage. The valve body and the filler culvert are all precision casting. The valve body adopts flange-type integral casting. The material can be 304, 316, 316L, WCB, 2Crl3 according to the user's needs. The sealing ring is made of PTFE-reinforced Teflon, corrosion-resistant, Wear-resistant, no slag.
5. The full circular DC channel design has no slag or jamming.
6. The scientific design of the sealed packing makes the upper seal safe, effective and durable.
7. Short structure length can save raw materials, installation space, and effectively support pipeline strength.
8. The guide block on the knife gate body causes the gate to move correctly. The squeezing block ensures effective sealing of the ram.
9. Knife gate valve can also choose any drive mechanism.
10. V-shaped gate can be used as a regulating valve.
11. Compact design, small footprint, light weight, cheap, easy to install, wear-resistant anti-blocking measures, easy maintenance, easy to use and long life, and can choose any drive device.
12. The valve plate has multiple support points so that the valve plate has a good self-alignment. When the valve is closed and subjected to back pressure, the valve plate does not shift
