Wenzhou Valve Co., Ltd. specializes in manufacturing Goodwill ceramic, enamel, wear special valve products. Ceramic valve using high-performance structural ceramics, it has good self-cleaning, super wear-resistant, highly corrosive, self-lubricating, wide and long service life, the use of the environment, especially suitable for use in the chemical industry. In the chemical industry, coal, petroleum, and so harsh environment metal valves no longer meet the high wear, corrosion and other harsh conditions and strong demand, mainly in the metal valve easy to leak, torque, sealing surface impatience corrosion situation. From traditional metal valves needed overhaul materials, design and processing technology and other aspects. 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 both manual and electric drive. This series of products using flange connection, use the range: 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. With ordinary metal valve is different, the use of structural ceramics made of ceramic valve seal pair, valves and wetted parts materials are used in structural ceramic materials, avoid direct contact with the medium may cause corrosion. Stable structure and chemical properties of ceramics, high hardness, resistance to most of the acid corrosion, its excellent corrosion resistance, high temperature resistance, abrasion and erosion resistance, can replace the entire valve manufactured using precious metals and the life of the entire valve manufactured using precious metals longer valve life is ten times the normal metal around, greatly improved the harsh conditions, the valve seal vice easily damaged, use life of less than system maintenance cycle requirement, to high cost advantage is gradually replace similar metal valves. Ceramic valve for power plant ash is mainly designed arch system, the valve is not only resistant to wear, and very suitable for soft and hard slurry 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 gate 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 a valve casing thickness exceeds the national standard GB, JB and American Standard ANSI standard data requirements, the main material and mechanical properties of chemical elements meet the state standards. Three sections of casing 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, ensure the valve stem has good mechanical properties and corrosion resistance. Third, the built-in buffer compensating spring washer to ensure a stable and good sealing. And contains impurities referral, the ball is not easy to get stuck cause rupture. Fourth, the whole contact surface of the ceramic lining hard sealing ball in contact with the media are all of the structure of a ceramic material, together with its chemical stability, high hardness (hardness HRA88 above, after the diamond) characteristics. Accordingly, the ceramic has a high compressive strength, high wear resistance and excellent resistance to oxidation and corrosion resistance, high temperature resistance, good thermal insulation properties. Five, with the precision grinding technology and advanced machinery and equipment manufacturing. Valve structure is simple, smooth runner, medium flow resistance. Hard hermetically sealed ceramic inner parts, 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 precision, good surface quality, so that the entire valve torque light , resistance, sealability achieve zero leakage. 1. By cleaning pipes to extend the life of ceramic valve in the piping system, there will be some debris, such as welding slag, rust, lime slurry solidified slag, wire, cloth, etc. These contaminants distributed in the orifice and a guide parts, can easily cause pipe blockage or stuck valve spool fragmentation. These common failure usually occurs in the early commissioning of the new system is put into operation and overhaul. Encounter such cases, you must remove the valve open for cleaning, in addition to the dregs thereof, such as the sealing surface damage should grind; while the bottom plug opens to punch the dregs thereof, and flushing the pipeline. Put into operation before, so regulating valve fully open, let the media 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%. This, and other impurities in the line is cleared, the opening degree of the regulating valve is then adjusted to the normal opening degree slightly larger where damage to the valve as the fluid flow rate continues to increase, a corresponding decrease in the degree of opening, so that by continuously 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 so far. 3. By increasing the diameter to increase the life of the CV values ??calculated by the formula, we calculate the correct CV to select the appropriate valve suitable caliber. 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 can be adjusted freely within a range appropriate to increase the diameter of the valve, the wear can be reduced. 4. improve life by shifting the position in order to protect the sealing surface damage 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, the fluid part of the fastest places below the fluid imports. Ceramic regulating valve now mainly a three-piece structure, we can use the ball core commutation, one can use the four ball core at the inlet, the valve life will be extended by 4 times. 5. By changing the structure to improve the life of ceramic valve regulating valve using three type structure, with a double seat, double sealing. In the selection of the ceramic ball valve when try to choose a transition ramp designed valves, such as valve to reduce the impact of the fluid, thus prolonging life.
