9, high seal packing structure Leakage in the valve, traditionally tend to focus on the seat leakage, that is, leakage, while ignoring the filler Department of leakage, that is, leakage. In fact, it is an indisputable fact that in the present-day society where the environmental issue is being increasingly emphasized, it is an indisputable fact that the leakage is far more harmful than the internal leakage. Tritec three eccentric butterfly valve is a rotary valve, the valve stem action only 90 Â° rotation only, which is the gate valve, stop valve and other stem action for the spiral multi-turn reciprocating motion, the filler part of the wear level is low, relative The Tritec has been designed to the highest standards for leak proof construction, such as packing seals, to ensure that the standard seal performance is guaranteed to be less than 100 ppm when subjected to the external leak test in accordance with the EPA21 specification. In fact, in the existing Tritec test results, the external leakage was as low as 7 ppm with Lloyd's monitoring. These metrics mean that Tritec can work in toxic and hazardous media lines in a variety of fields, including chemicals. The application of three eccentric butterfly valve In summary, the three eccentric butterfly valve as the crystallization of the latest technology, Yang a variety of valve length, to avoid a variety of short valves, will be more and more users and designers attention. The butterfly valve Tritec, the maximum pressure level can reach 2,500 pounds, the standard caliber can be 48 inches, but also on the folder, lugs, flange, ring, butt welding, jacket, a variety of structural lengths Can correspond to, but also because of Tritec material choice is very large, high and low temperature and various acids, alkalis and other corrosive media also can be freely. Especially in the large caliber, with its zero leakage advantage, the shut-off valve, is constantly replacing the coarse gate valve and ball valve, the same, with its excellent regulation function, the control valve, is also constantly replacing bulky Stop valve. As a matter of fact, so far, Tritec has been used in various important pipelines such as China's oil and gas exploration, offshore platforms, petroleum refining, petrochemicals, inorganic chemicals, energy generation and other major industrial processes such as process control.
According to their uses, Ceramic Balls can be mainly divided into filler balls and grinding ceramic balls. Filler balls are widely used in petroleum, chemical industry, chemical fertilizer, natural gas, environmental protection and other industries, as the covering support materials and tower packing of catalyst in the reactor. It has the characteristics of high temperature and pressure resistance, low water absorption and stable chemical properties. It can withstand the corrosion of acid, alkali and other organic solvents, and can withstand the temperature change in the production process.
The main function of the filler ceramic ball is to increase the gas or liquid distribution point, support and protect the active catalyst with low strength. According to the different Al2O3 content of the Inert Alumina Ceramic Ball, the filler ceramic ball is divided into: Ordinary ceramic ball, inert Alumina Ceramic Ball, medium alumina ceramic ball, High Alumina Ceramic Ball, 99 high alumina ceramic ball, convex and concave groove open hole ceramic ball, active ceramic ball, open hole ceramic ball Ball, microporous ceramic ball, regenerative ceramic ball.
According to the different content of Al2O3, grinding ceramic balls are divided into silicon carbide grinding ceramic balls, microcrystalline aluminum grinding ceramic balls and high aluminum grinding ceramic balls. It has the advantages of high density, high mechanical strength and good wear resistance. Grinding ceramic ball is an economic and widely used non-metallic grinding medium. Grinding ceramic ball is mainly used in mechanical, electronic, aerospace and other fields, as well as chemical fertilizer and other industries. It is used for ball mill, can mill, vibration mill and other fine grinding equipment. Grinding ceramic ball has the advantages of high hardness, large volume density, corrosion resistance, etc. its grinding efficiency and wear resistance are much better than that of common pebble or natural pebble. It is widely used in ceramic, glass, enamel, pigment, chemical industry and other industries.
