No, the electric push rod sector blind valve is also called the electric push rod sector glasses valve. The fan-shaped flap of electric push rod is mainly composed of left valve body, right valve body, valve stem, gate, sealing ring, electric push rod and other parts, and it is a rigid structure composed of base and supporting column. The sealing part adopts stainless steel and rubber sealing ring, which has good sealing performance and long service life. The sealing ring is installed on the ram, which is convenient for replacement during maintenance. The rubber sealing ring is clamped on the ram. The blind valve of electric push rod can be remotely controlled by a single device or by multiple networked devices. Under abnormal conditions, it can also be manually operated by the valve itself. Overview of fan-shaped blind valve products: This series of fan-shaped blind valves, also known as glasses valves, flap valves and fan-shaped valves, are reliable devices for cutting off gas media required by GB6222 "Gas Safety Regulations for Industrial Enterprises". Widely used in industrial and mining enterprises, municipal, environmental protection and other industries in the gas medium management system, especially suitable for the absolute cut-off of harmful, toxic and flammable gases. It is also suitable to be a blind plate at the end of the pipeline to shorten the maintenance time or facilitate the connection of new pipelines. Compared with other valve devices for absolute cutting in pipelines, this series of fan-shaped blind valve has the characteristics of novel structure, light weight, small volume, convenient operation, quick action and absolutely reliable gas cutting performance.
Second, the electric push rod blind valve F9T43X working principle:
Electric push rod blind flange valve F9T43XF43X Manual sector blind flange valve consists of left valve body, right valve body, middle valve body and three connecting screws. Turn the connecting screw with a wrench to clamp and loosen the left and right valve bodies, and realize the opening and closing by changing the positions of the blind plate and the through hole plate on the gate. The valve has the characteristics of simple structure, light weight, reliable performance and convenient operation. The valve is a short structure series, and rubber sealing rings are installed on the left and right valve bodies respectively.
