Soft sealing materials in the process of opening and closing, closely with the seat to maintain a certain distance, make the soft sealing material closely in the background of fold without friction press office. 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. Q: analyze the soft tightly closed gate technology preset scheme of friction was answer: a, technology environment: the existing gate valves in the valve body, valve cover, and all things are in good condition, just a bit tight sealing faces variant or corrosion, the valve can not use. Tightly closed set of pipeline transportation of liquid and the isolation device inside the valve core, from the impurities and corrosion of liquid ZuGeng. 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. 。 Three, the practical scope: size & amp; φ; 50 - & φ; 400 mm, pressure 2. 5 - 4. 0 mpa, less than 200 ℃ of liquid at room temperature 4, technical scheme: this valve as double parallel slide Marine valve, inlet tightly closed form, the inlet valve plate by tightly closed set and unloading force become main tightly closed gate valve plate group. Second, creating goal: to solve the seat and disc tightly closed surface corrosion or variant, the valve plate can semi-automatic repaid and compression tight sealing faces and the soft tightly closed gate valve pressure between semi-automatic equilibrium problems, solve the soft tightly closed material 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. 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. The outside of the valve plate set with corrosion resistant rubber tightly closed set. 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. Three, it is very important when you use the occasion or the environment is more complex, would you please provide design drawings and detailed parameters, our engineers experts will concentrate on review and analysis for you.
