The gate size is big, take up the space is large. Used in the sulphuric acid systems in burning sulfur, transformation, dry absorption section, is the first selection of sulphuric acid plant with valve brand, by the broad masses of users feel is: tightly sealed performance is good, work light, corrosion, high temperature resistant, convenient operation, flexible use of safe and reliable, butterfly Industrial Valves, obtained more promotion of use. Manual wafer butterfly is a state level key new products, high-performance manual butterfly sees fit and using a double injustice and a special oblique cone duck egg circle tightly closed structure. (5) can be based on user requirements is equipped with pneumatic, electric actuator, satisfied with remote sensing and program requirements. All landowners back-to-back structure diversification, clamp, flange, butt welding. (3) clever clever wedge preset make valve has closed more and more tightly Marine valve semi-automatic tightly closed function, tightly closed between surface have to repay, zero leakage. Butterfly valve not only in fuel, liquefied gas, chemical industry, water treatment and other common industry wide application, and also used in thermal power plant cooling water system. Tightly closed metal can be suitable for high temperature, the lack of flexibility tightly closed with the temperature limit is. Butterfly valve in the full paper and position, the butterfly plate thickness is only the resistance of the medium flows through the body, because this initiation by after the valve pressure drop is small, so it has good flow stem special properties. Wafer butterfly valve with double screw the valve signatures in place between two pipe flanges and flanged butterfly valve is a valve with flange, with the screw on the valve flange on both ends a petition on the pipe flange. B, use: used in sulphuric acid industry gas pipeline before furnace blower entrance, entrance relay fan, electric mist networking and unicom valve, entrance S02 main blower, converter, preheater entrance etc to adjust and use by the mind. Butterfly valves are tightly closed and metal tightly closed two tightly closed type. See fit and use metal than ordinary elastic tightly closed tightly closed valve valve live longer, but it's hard to do absolutely tightly closed. A, manual wafer butterfly valve and gate valve performance comparison of nominal pressure and nominal diameter of the same normal butterfly valve and gate valve which was better, not easy to leak? Tightly closed gate valve than butterfly valve is better, but there is also a manufacturer of butterfly valve tightly sealed good performance. And only need to rotate for 90 & amp; 度; Can rapid opening and closing, simple operation, at the same time the valve have satisfactory curb the special nature of the fluid. C to injustice and unique structure of (1) three unique special preset made tight sealing faces no friction between the transmission, extended the valve use fixed number of year of survival. The structure principle of butterfly valve particularly adapt to the manufacture of large diameter valves. To solve the traditional injustice butterfly valve in the opening and closing 0 & amp; 度; ~ 10, 度; At the disadvantages of tightly closed surface is still in the sliding contact friction and successfully implemented the butterfly plate in the moments tightly closed on faces, the clutch, close contact that is tightly closed effect, prolong the use of fixed number of year of survival, tightly closed best performance goals. Commonly used butterfly valve, which has two kinds of the wafer butterfly valve and flanged butterfly valve. (2) by the torque initiation elastic tightly closed. If asked butterfly valve as a traffic stem is applied, the main is accurately select the valve size and type. Q: manual work and classification of wafer butterfly answer: manual wafer butterfly butterfly plate installed on the diameter of the pipe direction. The wafer butterfly valve has simple structure, large and small, light weight, only by a few parts. Elastic tightly closed valves, tightly closed circle can be embedded in the body or attached to the butterfly plate peripheral. Specific chosen moment, also thinking about problems of medium temperature, the valve tightly closed and packing. Rules of nominal diameter greater than 50 with butterfly valves. 6 change parts material can be suitable for use in a variety of media, and can implement the lining anticorrosion ( Lining F46, GXPP, PO, etc. ) 。 Butterfly valves have a big and small, small footprint. Also widely used in: chemical, petrochemical, metallurgy, medical medicine, food and other industries of SO2, steam, air, gas, ammonia, CO2 gas, oil, water, salt water, alkali, water, nitrate acid, hydrochloric acid, sulfuric acid, phosphate and other media on the pipeline as the adjusting and application of river closure device. Cylindrical channels in butterfly Industrial Valves body, disc disc around the axis of rotation, rotation character of 0 & amp; 度; - 90 & 度; Between, rotate to 90 & amp; 度; When valves are brand the whole piece of paper. (4) large and small, light weight, light operation, easy to install.
