Free door-to-door selection and quotation for customers, mid-line type for fire protection The dedicated signal butterfly valve is a self-developed centerline butterfly valve with the introduction of foreign advanced technology. It has the advantages of simple structure, reliable sealing, light opening, long life, and convenient maintenance. Therefore, it is widely used in various pipelines of water supply and drainage, building fire protection and other systems, especially in fire protection pipelines. Electric valve butterfly valve, butterfly valve, pneumatic electric valve butterfly valve, factory direct sales, price concessions, electric valve butterfly valve manufacturer, welcome to consult, electric valve butterfly valve manufacturer consultation valve, ventilation equipment, high quality, quality assurance D971X fire-proof special explosion-proof electric butterfly valve with coal safety The explosion-proof certificate is small in size, light and cheap, reliable in performance, simple in matching, and large in circulation. It is especially suitable for occasions where the medium is viscous, contains particles, and fibers. It is widely used in industrial automatic control systems in food, fire protection, environmental protection, light industry, petroleum, papermaking, chemical industry, teaching and scientific research equipment, and electric power industries. It belongs to a variety of electric valves and electric regulating valves. Electric butterfly valve connection methods mainly include: flange type and wafer type; electric butterfly valve sealing forms mainly include: rubber seal and metal seal. The electric butterfly valve controls the switch of the butterfly valve through the power signal. The product can be used as a shut-off valve, control valve and check valve for piping systems. With manual control device, once the power failure occurs, it can be temporarily operated manually without affecting the use. Working principle of explosion-proof electric butterfly valve for fire protection    is a valve that uses a disc-type opening and closing member to reciprocate about 90° to open, close or adjust the flow of the medium. Not only the structure is simple, the volume is small, the weight is light, the material consumption is low, the installation size is small, the driving torque is small, the operation is simple and fast, but it also has good flow regulation and closing and sealing characteristics at the same time, and it is widely used. The variety and quantity used are still expanding, and are developing towards high temperature, high pressure, large diameter, high sealing performance, long life, excellent adjustment characteristics, and one valve with multiple functions. Its reliability and other performance indicators have reached a high level. With the application of chemically resistant synthetic rubber to butterfly valves, the performance of butterfly valves can be improved. Because synthetic rubber has the characteristics of corrosion resistance, erosion resistance, dimensional stability, good resilience, easy forming, and low cost, synthetic rubber with different properties can be selected according to different requirements to meet the operating conditions of butterfly valves. Explosion-proof electric butterfly valve for fire protection Product features Electric butterfly valve body only requires minimal installation space, and the task principle is easy and reliable. 2. The electric butterfly valve has great flow performance, and the pressure loss through the valve is extremely small. 3. Electric butterfly valve has obvious economic efficiency, especially butterfly valve with larger diameter. 4. The valve body of the electric butterfly valve is matched with the standardized convex pipe flange. 5. The electric butterfly valve has approximately equal percentage flow characteristics, which can be used for regulation or on-off control. 6. The electric butterfly valve adopts a special valve seat seal, which is suitable for liquid and gas with relatively clean medium. 1. The operating torque is small, labor-saving and lightweight. 2. The flow characteristics tend to be straight, and the regulation performance is good. 3. Achieve complete sealing and zero gas test leakage. 4. The structure is simple and compact, and the 90°rotation opens and closes quickly. 5. Choose different parts and materials, which can be applied to a variety of media. 6. The number of opening and closing tests is as many as ten thousand times and the service life is long. 7. Small and light, easy to disassemble and repair, and can be installed in any position.
