Detailed Product Description: | Professional manufacture of ceramic, enamel, wear special valve products. The use of high-performance structural ceramics ceramic valves, it has good self-cleaning, wear-resistant, strong corrosion, self-lubricating, wide and long service life, the use of the environment, particularly suitable for use in the chemical industry. In the chemical industry, coal, oil, and so harsh environment metal valves no longer meet high wear, corrosion and other harsh conditions demand, mainly in the metal valve easy to leak, torque, sealing surface corrosion intolerance situation. Traditional metal valves needed from revolutionize materials, design and processing technology and so on. The ceramic material used in industrial valves is a bold and useful innovation. Ceramic ball is widely used in power plant desulfurization systems, washing beneficiation systems, fluid flow control systems, chemical industry and other highly corrosive applications. Ceramic double plate valve engineering ceramic double plate valve can be divided into two kinds of manual and electric drive. This series of products using flange connection, use the range as follows: 1 power plant ash - dry ash handling system; 2 Concentrator - dry ore powder material selection, transportation; 3 cement industry - dry material handling, discharge. ; 4. Flour - Flour pipeline. Ceramic valve, also known as ceramic or ceramic-way valve, check valve, flow refers to rely on the media itself automatically open and close the valve, the valve is used to prevent the media back. Ordinary metal valve is different, ceramic valve seals using structural ceramics made deputy, valves and wetted parts materials are made of structural ceramic materials, avoid direct contact with the media may cause corrosion. Stable structure and chemical properties of ceramics, high hardness, corrosion resistance, most of the acid medium, and its excellent corrosion resistance, high temperature, wear and erosion resistance, can replace the entire valve manufactured using precious metals and the life of the whole of the precious metal valve longer valve life is ten times the normal metal around, greatly improved the harsh conditions, the valve seal pair easily damaged, use System maintenance cycle life of less than required in the circumstances, to high cost advantage is gradually replace similar metal valve. Ceramic valve mainly for thermal power plant ash arch system and design, the valve is not only wear resistant, and very suitable for soft and hard paste slurry medium, can also be in the water. Oil. Steam one-way flow of pipeline and other media used. Ceramic knife gate valve, also called ceramic knife-shaped valve, ceramic knife gate valve. It is the gate opening and closing pieces, the direction of movement of the fluid direction perpendicular to the gate, can be cut by the knife-edge gate fiber material to cut the media. Ceramic knife gate valve chamber does not actually exist, lift gate on the side of the guide groove by protruding ears pressed against the bottom of the seat, when To achieve a higher dielectric sealing O-ring seal can be used two-way valve seal. A valve casing thickness exceeds the national standard GB, JB US standard ANSI standard data requirements, chemical and mechanical properties of the main elements of the material meet the state standards. Three sections of the shell structure design, size rugged good looks. Second, the stem material chemical elements meet the state standards, Seiko fine grinding, the surface of the resist nitriding or quenching, ensuring the stem has good mechanical properties and corrosion resistance. Third, the built-in buffer compensating spring washer, to ensure stable and good sealability. And medium containing impurities, it is not likely to cause the ball stuck rupture. Fourth, the whole lining hard seal face contact with all wetted ceramic ball are structural ceramic materials, the chemical stability combined with high hardness (hardness HRA88 above, after diamond) characteristics. Accordingly, the ceramic has a high compressive strength, high wear resistance, excellent resistance to oxidation and corrosion resistance, high temperature resistance, good thermal insulation properties. Fifth, with the precision grinding technology and advanced machinery and equipment manufacturing. Valve structure is simple, smooth runner, medium flow resistance. Hard ceramic seal trim, consists of six pieces of scientific and rational design composition, valve ball, valve seat surface contact processing, making the ball closely integrated with internal and external R Block R, round ball high accuracy, good surface quality, so that the entire light valve torque small resistance, sealing achieve zero leakage. 1. pipe cleaning to prolong the life of ceramic valve in the piping system, there will be some debris, such as welding slag, rust, lime slurry solidification of slag, wire, cloth, etc. These contaminants located in the orifice and a guide site, can easily cause the pipe is clogged or stuck valve spool fragmentation. These common failure usually occurs in the early commissioning of the new system put into operation and overhaul. Encountered such a situation, you must remove the valve open for cleaning, in addition to the dregs thereof as sealing surface damage should grind; while the bottom plug open to the dregs rushed things, and flushing the pipeline. Before commissioning, so regulating valve fully open, so that the medium flow for some time and then put into normal operation. 2. prolong life as much as possible by increasing the opening hours of work at the beginning of the use of ceramic valve maximum opening work, such as 80%. Thus, to clear the pipeline and other impurities, the opening degree of the control valve and then adjusted to the normal opening degree slightly larger place, damage to the valve as the fluid flow rate continues to increase, a corresponding decrease in the degree of opening, so that through continuous destruction, and gradually close the valve way to make full use of the entire spool, the spool until the roots and the sealing surface damage, can not be used up. 3. to improve life by increasing the diameter CV value calculated by the formula, we calculated the right to select the appropriate CV for the valve diameter. In the same flow, the valve diameter is smaller, the faster the flow rate of the fluid medium of erosion spool and seals are also more powerful. If the degree of opening adjustment range, and increase the valve diameter, it is possible to reduce wear. 4. To improve the life of destruction through the transfer position in order to protect the sealing surface and the throttle valve seat surface, we can seriously damage the local transfer to a secondary position. The most serious erosion of ceramic ball valve, fluid fastest place is part of the bottom of the fluid inlet. Now ceramic ball valve main three-piece structure, we can use the ball core commutation, a ball core at the inlet can be used four times, then the valve life can be extended four times. 5. By changing the structure to improve the life of ceramic valve regulating valve using three type structure, with double-seat, double-sealed properties. In the selection of ceramic ball valve when try to choose a beveled transition valve design, this valve to reduce the impact of the fluid, thus prolonging life. |
