Working principle of electric wafer butterfly valve

by:Sino Valves     2021-03-08
The electrical equipment of the electric wafer butterfly valve of the valve factory is a driving mechanical equipment with insufficient program control, automatic control and remote control of the electric clamp valve. The whole movement process can be controlled by the stroke arrangement, the rotation distance or the radial torsion. The characteristics and use of electric work are due to the type of electric pinch valve, equipment working system, and the location on the pipeline or mechanical equipment. This electric wafer butterfly valve adopts a wafer center plate structure, which is mainly composed of valve body, valve plate, valve shaft, valve seat and transmission device. The butterfly valve has a simple and compact structure, small and light, convenient for transportation, installation and disassembly; the opening and closing of 90° makes the switch fast. The electric butterfly valve has small operating torque, labor-saving and lightweight; good sealing performance, long service life, and zero leakage; its flow characteristic is similar to a straight line, and its adjustment performance is good. The structure characteristics of the electric butterfly valve of the wafer: 1. The design is novel and reasonable, the structure is unique, the weight is light, and the opening and closing is rapid. 2. Small operating torque, convenient operation, labor-saving and smart. 3. It can be installed in any position and maintenance is convenient. 4. The seal can be replaced, and the sealing performance is reliable to achieve two-way sealing with zero leakage. 5. The sealing material is resistant to aging, corrosion, and has long service life. Technical parameters of electric actuators Technical parameters of electric actuators: power supply AC110, 220, 380V, DC24, nominal diameter DN50~1200mm, output torque 50N·M~2000N·M, nominal pressure PN0.6, 1.0, 1.6Mpa, function selection Type: switch type, passive contact type, valve position signal feedback type, intelligent adjustment type. Applicable temperature ≤120℃, applicable to medium water, gas, oil and weakly corrosive fluid, input signal 4-20mA, 1-5V, 0-10V; output signal: 4-20mA, 1-5V, 0-10V. Easy to use: single-phase power supply, simple wiring; * * ball-shaped protruding structure, making observation more convenient; no refueling, no spot inspection, waterproof and rust-proof, installation at any angle. The protection device has double limit, overheat protection, and overload protection. The total travel time is 5 seconds, 10 seconds, 15 seconds, 30 seconds, 45 seconds, 60 seconds. And with manual function. The built-in module adopts advanced computer single chip and intelligent control software to directly receive standard signals (4-20mA DC /1-5VDC) output by computers or industrial instruments to realize intelligent control and precise positioning of valve opening. Important indicators of the wafer butterfly valve: the average pressure produced is higher than the accurate fixed pressure, and no overheating is output. Because the natural gas (high degree of compression) unit, air pressure, and oxygen content difference cannot meet the flow requirements. Corresponding installation of the guided synchrotron: select the interval radial synchronous installation to remove the water in the middle radial direction. The guided synchrotron relies on the hydraulic center of the output shaft to press the air interval to the lowest point. When installing, you need to be level and consider how to move, so start from the normal level of movement. It is the most common industrial pipeline valve, one species, the clip-on butterfly valve structure itself is relatively small, only the end of the pipe flange to the middle butterfly, through the flange and the pipe butterfly clamp lock, you can bolt control the medium in the fluid pipeline. The clip-on butterfly valve is especially suitable for narrow spaces between pipelines or short distances. In the fully open position, the thickness of the disc is only when the medium flows through the body resistance, so the pressure drop generated by the valve is relatively small.
