Electric enclosed plug-in valve structure and working principle

Electric enclosed plug-in valve structure and working principle Electric closed-type flap valve consists of main and auxiliary valve body, valve plate, telescopic joint, fixed sleeve, electro-hydraulic push rod clamping mechanism, walking electric equipment, limiter, left, It consists of components such as the right valve body. Close valve: The electro-hydraulic push rod drives the spring clamping mechanism to disengage the valve plate. After the position is reached, the walking electric device starts, and the driving valve plate travels from open to closed. After the position, the electro-hydraulic push rod moves in the opposite direction, and the spring clamps. The mechanism automatically clamps into place and closes the valve. Opening the valve is the opposite. Open-type flapper valve and closed flapper valve are suitable for metallurgical, chemical and municipal gas pipelines, and comply with the provisions of GB6222-86 "Gas Safety Regulations for Industrial Enterprises". When the electric closed flapper valve is closed, the medium in the pipeline is completely cut off to achieve zero leakage of the seal. The electric enclosed flapper valve product can be operated on site and remotely, and is an ideal gas and harmful and toxic gas. Pipe network security partition equipment. Main performance specifications of electric enclosed flapper valve: Nominal diameter (mm): DN800-3600 Nominal pressure (MPa): 0.05, 0.1, 0.25 Applicable temperature (°C): ≤ 260 Applicable medium: Gas, toxic, harmful, flammable Gas connection flange standard: conforms to GB9115-2000 Electric closed type plug valve structure features: The plug valve consists of front valve body, rear valve body, valve plate, telescopic body, left and right sealed box body, through plate and blind plate and switching device , loosen the clamping device and other components. The loosening and clamping device of the metallurgical valve is driven by an electric device, and is connected by a sprocket, a chain and a screw nut pair to drive the bellows to expand or contract to realize clamping or loosening of the valve body sealing seat. The valve adopts a sprocket type multi-point clamping mechanism. The sealing ring is double-sided sealed and mounted on the valve plate. The sealing is reliable and easy to replace. The top rail of the valve plate is provided with a longitudinal and lateral moving mechanism, and the side is provided with a spring mechanism and a limit wheel. When the clamping mechanism is released to release the valve plate, the spring mechanism tops the floating valve plate to the limit wheel. Electric closed flapper valve ordering instructions: When ordering the electric closed flapper valve, please indicate the valve type, specification and temperature of the selected electric closed flapper valve. Please specify if you have special requirements.
