The characteristics of the knife gate valve can be summarized into the following thirteen points:
1. The sealing surface of the gate can be lifted, which can scrape off the adhesive on the sealing surface and automatically remove the sundries.
2. The stainless steel valve body is durable, the valve body reinforcement design improves the valve body strength, and the double-head screw is used to open and close more quickly.
3. The full-circle DC channel design has no slag and no jamming.
4. The scientific upper sealing stuffing box design makes the upper sealing safe, effective and durable.
5. Short structure length can save raw materials, installation space, and also effectively support pipeline strength.
6. The triangular bracket saves raw materials and ensures the required mechanical properties.
7. The guide block on the valve body of the knife gate valve makes the gate move correctly. The extrusion block ensures the effective sealing of the gate.
8. Knife gate valve can also choose the drive mechanism arbitrarily.
9. The V-shaped gate can be used as a regulating valve.
10. Compact design, small space occupation, light weight, low price, easy installation, perfect wear-resistant and anti-blocking measures, easy maintenance, convenient use and long service life, and the drive device can be selected arbitrarily.
11. The valve plate has 5 supporting points, so that the valve plate has a good self-centering. When the valve is closed and subjected to back pressure, the valve plate does not deflect.
12. Stainless steel gate can prevent seal leakage caused by corrosion, and fine grinding and polishing can obtain better sealing effect. The bottom end of the blade is processed into a blade shape, which has the function of cutting off soft materials such as fiber, paper pulp and wood pulp, and has a good opening and closing function at the same time. A hard polytetrafluoroethylene scraper is installed at the top of the blade, which can prevent dust, grit and other abrasive substances from entering the stuffing box, which can significantly improve the life of the blade.
13. The overall stainless steel material can prevent corrosion damage. The valve body and packing culvert are all precision casting. The valve body is integrally cast by flange type. The material can be 304, 316, 316L, WCB, 2Crl3 according to user needs. The sealing ring is made of PTFE reinforced polytetrafluoroethylene, which is corrosion-resistant and Wear-resistant, non-stick slag.
