Knife type gate valves have a simple and compact structure, reasonable design, light material saving, sealing is reliable and flexible operation of the light, small volume, the channel smooth, flow resistance small, light weight, easy to install, easy to remove etc, and thoroughly solved the ordinary gate, flat gate, globe valve, control valves, butterfly valves, ball valves, such as the weight of the valve, the resistance to flow with large area, difficult to install other complicated problem, can replace gm cut-off valve and regulator, can be in work pressure 1.0 MPa - 2.5 MPa, using temperature - 29-550 ℃ cases work normally. Knife gate valves with shear type wedge giant-cell function, you can stick on sealing things, automatically remove debris, stainless steel gate can prevent corrosion cause seal leakage.

Knife made according to different type gate valve stem and darker caliber Ming stem two forms (dark stem 900mm, rising stem (~ (2 "to 900mm).

Knife gate valve can be made within type V, triangle, pentagon channel. V type can be used as an adjustment control gate.

Knife gate valve connection form of a wafer, flange a ear type, seal the metal to metal hard seal are of polyurethane, metal, with enhanced ptfe soft seal.

According to the transmission way knife type gate valves can be divided into: manual (the handwheel, manual zipper), worm gear and worm drive (positive gear transmission, bevel gear transmission), pneumatic, electric, pneumatic, etc.;

According to the control mode knife type gate valves can be divided into: manual control, pneumatic control, electromagnetic control, simulated the remote computer control.

Knife gate valves scope of

Knife gate valve suitable for mining type coal cleaning plant, slag discharge, urban sewage treatment, food, paper making, pharmaceutical, oil and chemical oil, water, steam piping, connected or truncation pipeline slurry, the gold ore, ore, slag, coal slime, pulp, wood pulp, tailing, fiber, dust, chemical processing sewage, traps, asphalt, bunker export, fruit, grain, slaughterhouse wastewater, and other media.

Knife gate valve product characteristics of

1. The disc sealing surface can promote giant-cell seal surface, the adhesion of content, automatic cleanup sundries.

2. Stainless steel gate can prevent corrosion cause seal leakage, fine grinding can obtain better polishing sealing effectiveness. Knife plate bottom processed into the blade shape, such as fiber, of soft materials, wood pulp with cut function, but have a good opening and closing function. In dao plate top installs a hard ptfe mud scraper device, can prevent dust, such as sexual material into the scratch gravel packing box, can significantly raise knife plate life.

3. Stainless steel body established long durable, body reinforcement design improve body strength, double screw use lifts more rapidly.

4. Overall stainless steel material, can prevent corrosion damage. Body, packing culvert are precision casting, including body using flange type integral casting, material can be based on user needs to choose 304, 316, 316L, WCB, 2Crl3, sealing ring adopts PTFE enhanced PTFE material, corrosion resistance, resistance to wear, not to be stained with slag.
5. All round dc channel design don't store slag, BuKa resistance.

6. Scientific sealed the stuffing box design, make sealed is safe and effective and durable.

7. Short structure length, can save raw material, installation space, also effectively supports pipeline intensity.

8. Triangular stents save raw material, the mechanical properties of needed to guarantee.

9. Knife gate valve body the orientation of the wedge blocks right motor. Extrusion block guarantee sluice effective seal.

10. Knife gate still can choose any type drive.

11. V type disc can be used as regulator use.

12. Compact design, occupy the space small, light, cheap, easy to install, wear-resisting prevent measures to improve and convenient use, convenient in maintenance and long service life, and can be arbitrarily choose device drivers.

13. The disc has five anchor, make the disc to have very good since.
