Thirteen Characteristics of Knife Gate Valve

Knife-type gate valve has the advantages of simple and compact structure, reasonable design, light materials, reliable sealing, light and flexible operation, small size, smooth passage, small flow resistance, light weight, easy installation, easy disassembly and other advantages. Gate valves, globe valves, regulating valves, butterfly valves, ball valves and other valves of heavy weight, large flow resistance, large area, difficult to install and other difficult problems, can replace the common cut-off valve and control valve, the working pressure of 1.0MPa-2.5MPa, Temperature -29-550 ℃ under normal circumstances. Knife gate knife gate has a shear function, scraping the sealing surface of the adhesive, automatically remove debris, stainless steel gate to prevent corrosion caused by the seal leak. Knife-type gate valve for mining coal-fired power plant, slagging, urban sewage treatment, food, paper, medicine, petroleum, chemical and other oil, water, steam pipeline, connect or cut off the pipeline slurry, gold Powder, Ores, Slag, Slime, Pulp, Wood Pulp, Tailings, Fibers, Dust, Chemical Wastewater, Sedimentation Tanks, Bitumen, Silo Exports, Fruits, Cereal, Slaughterhouse Wastewater and other media. 1. Can improve the sealing surface of the shutter, can scrape the sealing surface of the adhesive, automatically remove debris. 2. Stainless steel gate to prevent corrosion caused by leakage seal, grinding and polishing can get better sealing effect. The bottom of the blade is processed into a knife-edge shape, the soft material such as fiber, pulp, wood pulp has cut off function, at the same time have a good opening and closing effect. In the upper edge of the blade is installed a hard Teflon scraper to prevent dust, gravel and other abrasives into the stuffing box, can significantly increase the life of the knife. 3. Stainless steel body durable, body rib design to improve the body strength, double-headed screw opening and closing more quickly. 4. The overall stainless steel, to prevent corrosion damage. The valve body and packing culvert are all precision castings, of which the valve body is flanged and integrally cast, the material can be selected according to user needs 304,316,316L, WCB, 2Crl3, PTFE reinforced PTFE ring PTFE material, corrosion resistance, Wear-resistant, non-stick residue. 5. Full circular DC channel design does not slag, no jamming. 6.Scientific seal packing design, so that the seal is safe and effective, durable. 7. Short structural length, can save raw materials, installation space, but also effectively support the pipe strength. Triangular bracket to save raw materials, to ensure the mechanical properties needed. 9. Knife gate valve body guide block to make the correct movement gate. Squeeze block to ensure effective sealing of the gate. 10. Knife gate valve can also choose any drive mechanism. 11.V-type gate can be used as a control valve. 12. Compact design, small footprint, light weight, low price, easy to install, wear-resistant anti-blocking measures to improve, easy maintenance, easy to use and long life, and optional drive. 13. Valve plate has 5 support points, so that the valve plate has a good self-aligning. When the valve is closed, and withstand back pressure, the valve plate does not shift.

Aluminium Skirting Board

Aluminum alloy skirting line,Skirting Board, light Baseboard,aluminum corner extrusion is a new decorative material or replacement product of modern decoration. Like the skirting lines of all materials in the past, it plays a role in visual balance, beautifying decoration, corner and ground protection in the decoration space. With the development of social economy and the improvement of quality of life, the quality requirements of human living space are also changing. Decorative materials are also being rapidly updated. Aluminum alloy has the characteristics of high die-casting yield, compact casting, high strength, no fracture, strong flexibility, good copper plating and coloring effect, light specific gravity and good decoration effect. Concise, fashionable, beautiful and environmentally friendly, more and more are used in the decoration industry.

The aluminum alloy skirting line is an all aluminum L-profile product. The profile has a height of 6cm, 8cm and 10cm, and each length is 3M. The two fixed buckle grooves and waterproof rubber strip grooves on the back ensure the flatness of the product. The popular colors in the market include bright wire drawing, champagne wire drawing, titanium wire drawing, coffee wire drawing, black titanium wire drawing, gun color wire drawing, purple gold wire drawing and various spray oxidation.

Aluminum alloy skirting line is equipped with special internal and external corner accessories and fasteners.

1. Observe whether the corner ground and wall are flat. If it is not flat, level it with a shovel and clean it. Otherwise, the skirting line will be bent and uneven after being installed, and some will not be fully close to the wall, leaving ugly gaps.

2. Then saw a section of 15 cm long aluminum alloy skirting line, clamp the buckle on the groove on the back, lean against the wall and mark the hole of the buckle.

Before drilling, observe the wiring direction of water and electricity to prevent errors. The interval between boreholes shall not be too large, and it is generally about 40cm.

Drill holes in the wall with special tools, and then nail them into the newly drilled holes with plastic. Fix the buckle on the wall with screws. 3. The convex corner of the wall is called the external corner, and the concave corner is called the internal corner. The installation of internal and external corners is to draw the fixed point position on the wall with internal and external corners, then take holes and nail plastic, and then fix the internal and external corners on the wall corner with screws.

Note: since the pipes of hydropower projects are buried on the wall, the position of the pipe is directly below the switch socket. The position shall be calculated during drilling to avoid damage.

4. Finally, measure the size distance of each section with a tape measure, cut the corresponding size with a cutting machine and clamp it on the corresponding buckle. The length of each aluminum alloy skirting line is 3M. When exceeding the length of the skirting line, a fastener shall be installed in the middle of the interface to ensure the flatness of the skirting line.

The skirting line,Skirting Board, light Baseboard,aluminum corner extrusion should be completely close to the wall without leaving gaps, which is more beautiful, especially in the corner. The flatness of the wall shall be tested before installation.
