Electric adjustable knife gate valve dn1400

by:Sino Valves     2021-02-25
Electric adjustable knife gate valve dn1400 welcome to inquire, the product is safe and reliable, performance is stable, wear-resistant and corrosion-resistant. This knife-shaped gate valve is a new type of gate valve, small in size, light in weight, and light in material saving. It is sewage, coal slurry, syrup, mud Ideal products in industries such as, air, slag-water mixture, water supply, papermaking, and mining. Electric knife gate valve adopts metal to metal hard seal or metal to rubber soft seal. In the process of opening and closing, the gate and the sealing surface adopt a special design, which has less friction and is durable. The upper seal of this knife-shaped gate breaks through the conventional sealing form, and adopts the upper cover structure, so that the upper seal is changed from a large area rectangular seal to a small area circumferential seal, and the sealing performance is greatly improved. On the basis of the circumferential seal, the current international advanced floating seal is changed to an area circumferential seal, which greatly improves the sealing performance. On the basis of the circumferential seal, the current international advanced floating seal structure is adopted, so that the upper seal reaches the same life as the pipeline, thereby increasing the service life of the valve as a whole. The knife-type electric gate valve can prevent leakage to the maximum extent, and will play a positive role in improving production efficiency and protecting the environment. The sealing surface is made of highly wear-resistant and corrosion-resistant ceramic materials, and adopts inlay technology, which has high corrosion resistance and good wear resistance, so that the valve has a long life and the cost performance is 10 times higher than that of ordinary valves. Electric knife gate valve, also known as knife gate valve, knife gate valve, is suitable for pipelines with suspended particles, fiber materials, pulp, sewage, coal slurry, ash cement mixture and other media. It depends on the knife blade gate valve that can cut fiber materials. To cut these media. The valve body does not actually have a chamber. The gate is raised and lowered in the side guide groove, and is pressed against the valve seat by the bottom lug. If you need to achieve higher media tightness, you can choose an O-shaped seal valve seat to achieve Two-way sealing. What is the long-term prospect of the electric knife gate valve industry? The long-term prospects of the knife-shaped gate valve industry nowadays are great. The application of knife-shaped gate valves in diverse fields has been recognized by large users and equally praised. The support of customers has been continuously promoting the innovation and satisfaction of knife-shaped gate valve products. Knife gate valve is a more common type of gate valve. It has advantages such as small space required for installation, low working pressure, not easy to form stored debris and dust, and low cost. It is widely used in national mining, Used in steel to deal with coal, filter slag, etc., used in mud, waste water, sludge and water with some suspended matter as a cleaning device, in the paper industry, used to deal with the confusion of pulp and material water, and at the same time in power stations It is also used in ash removal. At the same time, it is accompanied by the steady and continuous growth of the state-owned economy, the recovery of the world economy, the rapid growth of national commerce, and the integration of our valve products into the international valve market, so that we can get more intimacy and exchange opportunities with the advanced skills of the world below. The favorable factors will effectively promote the valve market in our country, especially the continuous progress and growth of the knife gate valve manufacturing industry, and its long-term prospects in the future are also obvious. Then, under this opportunity, how can valve companies better seize this opportunity: First, the scope of companies is expanded, and the unity between companies is one aspect. Through corporate unity, mediation of product layout and skill exchange makes both sides stand out The advantages of the company can roughly complement each other to form a corporate group model. Secondly, to improve the diversified market in sales, mediate sales strategies, improve sales channels, expand the international market, get greater profits in export volume, and integrate into the international market industry. This will be a very tight catalytic condition! In general, the electric knife gate valve exists as a part of the whole machine. The processing technology, product quality, and reliability directly affect the efficiency, energy consumption, pollution, life and safety of the whole machine. index. Therefore, the status quo of valve technology and its development trend will cause a new round of technological innovation.   The biggest impact of similar foreign products on the electric valve industry is the application of new materials and the adjustment and performance extension of similar products. This impact is great and its degree varies.   Electric knife gate valve Since the existing corrosion-resistant valve materials cannot fully meet the needs of its technological development, the output of ultra-low carbon stainless steel valves is very small, so the foreign valve industry is accelerating the development of ultra-low carbon duplex stainless steel valves. Ultra-low carbon bidirectional stainless steel has the ability to resist pitting corrosion, intergranular corrosion, and uniform corrosion in environments such as chloride ion, hydrogen sulfide, carbon dioxide, inorganic acid, and organic acid. Secondly, the foreign valve industry pays more and more attention to the application of its nanomaterials in valves. In the equipment manufacturing industry, nano-materials can only reach the sub-nanometer level, and the powder used to manufacture valves is processed at the nanometer level. The original plastic particles are relatively large. After the new process, neatly arranged and fine powder particles can be obtained. After sintering and high temperature die-casting, the entire cavity of the valve is obtained. This plastic valve has good corrosion resistance and high In addition, the nickel-based nano powder is made by the carbonyl method, and the nickel-based nano powder is coated on the sealing surface by laser coating technology or supersonic coating technology, so that the hardness of the sealing surface can reach HRC62~70, which improves The wear resistance, erosion resistance and corrosion resistance of the sealing surface of the valve improve the service life of the pneumatic knife gate valve.
