The valve tightly closed material change is very convenient, so the use of the survival of the fixed number of year is 5 times more than ordinary gate valves. This valve for double parallel slide valve, entry tightly closed form, the inlet valve plate by tightly closed set and unloading force become main tightly closed gate valve plate group. Tightly closed set of pipeline transportation of liquid and the isolation device inside the valve core, from the impurities and corrosion of liquid ZuGeng. The existing gate valves in the Industrial Valves body, valve cover, and all things are in good condition, just a bit tight sealing faces variant or corrosion, the valve can not use. Q: extended soft tightly closed gate valve use fixed number of year of the survival of way: answer: a, technical solution: size & amp; φ; 50 - & φ; 400 mm, pressure 2. 5 - 4. 0 mpa, less than 200 ℃ of liquid at room temperature 2, practical scope: solve the valve seat and valve plate tightly closed surface corrosion or variant, the valve plate to semi-automatic reimburse and compress tightly closed surface and semi-automatic between valve and valve plate stress equilibrium problems, solve the soft sealing material closely due to problem of the friction and damage tightly closed, because the valve tightly closed sets can be change, greatly enhanced the use of the valve. Soft sealing materials in the process of opening and closing, closely with the seat to maintain a certain distance, Marine Industrial Valves to soft sealing material in the background of fold without friction press office. Three, technology environment: flexible soft tightly closed gate strengths is tightly sealed performance is good, is easy to lack of aging, wear, use the shorter survival of life. Tightly closed set and discharge valve plate synchronous movement but not cohesion force, pipeline pressure after unloading valve plate, leveling lever to export the seat, so will greatly increase the soft tight sealing faces together. The two tightly closed can supply each other, in terms of tightly closed soft tightly closed relatively well, but now hard tightly closed tightly closed can also be satisfied with the corresponding requirements. 。 Hard tightly closed using live longer, but the difference in comparing soft tightly closed tightly closed. The outside of the valve plate set with corrosion resistant rubber tightly closed set. plate with tight sealing faces do not have the friction when opening and closing or to detract from the friction, so can prevent all kinds of inadequate soft tightly closed gate valve. Because this using the unit gate is expected: variant, valve seat, valve plate tightly closed surface corrosion resistance, delicate tightly closed material can change. Professional factory can't repair these valve, so lead to a great deal of cost. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you. Second, if the valve has been selected by design unit of our company model, please order according to the valves parameters directly with our sales center.
