Jiangsu Lan valve General Equipment Co., Ltd. is a company specializing in research and development, production and marketing of high-tech enterprises valve electric device, always been committed to "leading technology, quality and efficiency, customer first, the undersigned about compliance" business philosophy. Valve flange connection: This is the valve most frequently used form of connection. Press the combination of surface shape can be divided into the following categories: 1, smooth formula: valve for pressure is not high. Processing more convenient 2, lenticular: Work pressure is high, titanium plug valves can be used in hard washer 3, tenon slot: Available plastic deformation larger washer, more extensive use in corrosive media, plug door, seal better. 4, trapezoidal trough: oval metal ring gasket for use in the working pressure ≥64 kg / cm of valves, or high temperature valves. 5, lens type: washer lens shape, made of metal. For operating pressure ≥100 kg / cm high pressure valves, or high temperature valves. 6, O-ring type: This is a relatively new form of flange connection, it is with the emergence of a variety of rubber O-ring, and developed, plug, sealing effect than on the flat washers generally reliable .江苏兰 valve General Equipment Co., Ltd. production of electric valve is not only simple structure, good sealing performance, but also to some of the smaller nominal diameter within the range of size, light weight, less material consumption, small installation size, x43w10p plug and drive torque is small, simple, easy to open and close fast, is one of the fastest growing valve varieties of the past ten years of development. Ball is evolved from the stopcock comes as its opening and closing parts of a sphere, the use of the ball around the stem axis 90 ° rotation to achieve the purpose of opening and closing. Ball valves in the pipeline is mainly used for cutting, distribution and change the direction of media flow, designed ball valve V-shaped opening also has a good flow regulation.江苏兰 valve (Figure), x14w10t plug, plug supplied by 江苏兰 valve General Equipment Co.江苏兰 valve General Equipment Co., Ltd. (www.lanfa.cn) strong, credible, in Changzhou, Jiangsu regulating valve industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Jiangsu Lan valve into the brilliant and you work for a better future!
