As we all know, due to the continuous development of society, the scope of application of valves is becoming wider and wider, so the materials for making valves are gradually no longer stainless steel, cast steel, etc. As a new material for industrial valves, ceramics are a bold and beneficial innovation, so ceramic valves have been loved by many businesses since they were launched. Using the wear resistance and corrosion resistance of ceramics to make wear-resistant and corrosion-resistant parts instead of metal materials is one of the important development directions of the high-tech material market in recent years. The ceramic valve originally used a two-piece structure. In order to make the structure of the valve more reasonable, it was changed to the commonly used three-piece structure. This structure also has the characteristics of double sealing due to its double valve seat. Do you know how to use ceramic valves? It doesn't matter if you don't understand, Lianke Valve Co.,Ltd. will introduce the use of ceramic valves in detail below. How to use the ceramic valve 1. Increase the opening degree to prolong the life. When starting to use the ceramic regulating valve, try to work at the maximum opening degree, such as 80%. In this way, the erosion and wear of the initial impurities in the pipeline occur outside the damaged part of the valve core. After removing the impurities in the pipeline, adjust the opening of the regulating valve to a place where the normal opening is slightly larger. , As the fluid damages the spool and the flow increases, the arc polishing machine reduces the opening accordingly, so that it is continuously destroyed and gradually closed, so that the entire spool can be fully utilized until the root of the spool and the sealing surface are damaged and cannot be used. . The use method of ceramic valve 2. Increase the caliber to improve the service life. We calculate the correct CV through the CV value calculation formula to select the appropriate valve caliber (standard). Under the same flow rate, the smaller the valve diameter, the faster the fluid flow rate, and the more severe the erosion of the valve core and seal by the medium. It is recommended that the user appropriately increase the caliber of the valve within the range where the opening can be freely adjusted, so as to reduce the wear and tear. How to use the ceramic valve 3. Clean the pipeline to prolong the life of the pipeline. Welding slag, rust, solidified slag, iron wire, cloth strips, etc. in the throttling port and the guide part of the arc polishing machine cause blockage or jamming and break the valve core , which often occurs at the initial stage of commissioning after a new commissioning system and an overhaul. This is the most common failure. In this case, it must be disassembled for cleaning to remove the slag. If the sealing surface is damaged, it should be ground; at the same time, the bottom plug should be opened to flush out the slag and flush the pipeline. Before putting into operation, let the regulating valve fully open, let the medium flow for a period of time and then bring it into normal operation. How to use the ceramic valve 4. Transfer the damaged position to improve the life. Transfer the severely damaged place to the secondary position to protect the sealing surface and throttling surface of the valve core and valve seat. Usually the ceramic ball valve
has the most serious erosion, and the fastest fluid velocity is the lower part of the fluid inlet. For the current three-piece structure of the ceramic ball valve, the ball core can be reversed for use, so that one ball core can be used at the inlet for four times, the life of the valve is extended by 4 times. Reasonable use of ceramic valves, maintenance to the maximum extent, and prolonging their service life are the primary issues of using ceramic valves. How to use the ceramic valve 5. Change the structure of the arc polishing machine to improve the service life The ceramic regulating valve originally adopted a two-piece structure. In order to make the valve structure more reasonable, it was changed to the commonly used three-piece structure. This structure has a double valve. seat, so it also has the characteristic of double sealing. At the same time, when choosing a ceramic ball valve, pay attention to choosing a valve with a sloped transition design, such a regulating valve can reduce the impact of the fluid. Nowadays, ceramic valves are used in electric power, petroleum, chemical industry, metallurgy, mining, sewage treatment and other industrial fields due to their special wear resistance and corrosion resistance. Ceramic valves can meet the high wear and strong corrosion environment, especially the outstanding feature is the long service life, and its performance-price ratio is far superior to other similar metal valves. Lianke Valve Co., Ltd. now has a complete management organization such as a valve scientific research and development center (valve technology center), a valve machining center, a valve quality inspection center, a valve market service center, and a financial settlement center. Especially in the research and development of fluorine-lined valves, the production of fluorine-lined valves, the inspection of fluorine-lined valves, and the performance of fluorine-lined valves.
