Electric actuator with valve
Structural features and uses
Metal seal butterfly valve series products are long-life, energy-saving butterfly valves. The products comply with the national standards JB/T8527-97 (metal seal butterfly valve), GB/T13927-92 (universal valve pressure test) standards and other related standards for valves. This product consists of valve body, butterfly plate, sealing ring, transmission mechanism and other main components. Its structure is designed using the three-dimensional eccentric principle, and a new processing technology compatible with elastic sealing and hard and soft multi-layer sealing enables the butterfly valve to reduce its torque force during operation, achieving labor-saving and energy-saving functions. This ensures the overall reliability of the butterfly valve in terms of corrosion resistance, high temperature resistance and wear resistance. This butterfly valve is suitable for use in food, medicine, petrochemical industry, power plants, steel plants, industrial environmental protection water treatment and high-rise buildings, as the best device to regulate flow and cut off fluids in water supply and drainage pipelines.
Features
1. The butterfly plate sealing ring is a soft and hard laminated metal sheet, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent sealing performance regardless of low or high temperature conditions.
2. Adopting a triple eccentric structure, the valve seat and the butterfly plate have almost no friction, and have a tighter sealing function as they are closed.
3. The sealing surface of the valve body is made of surfacing stainless steel and cobalt-based carbide. The sealing surface is wear-resistant and has a long service life.
4. Unique structure, flexible operation, labor-saving, convenient, not affected by high or low medium pressure, reliable sealing performance and long service life.

Product quality inspection before leaving the factory
1. Inspect the products produced on the electric actuator production line every day, 100% inspection. First, open the indicator cover and check whether the wiring is beautiful, whether the limit cams in the opening and closing directions are fully raised, and whether the pointer position is consistent with the actual position of the actuator. , whether the screws inside are tightened, check whether the back cover is correct, and check whether there is paint peeling on the appearance of the electric actuator. Dirt, manual wrench, waterproof connector, manual dust plug, sight glass, and sight glass gland are all installed. After everything is correct, use a laser marking machine to mark the product number on the back of the electric actuator. The product number should include the date of the day, and finally put the foam into storage.
2. Inspection of complete sets of valves: After the valve installation production line operator completes the debugging, he will take the production order to the quality inspector, and the quality inspector will check the production order and products one by one (inspection items: valve quantity, diameter, material, connection method. Whether the pressure is consistent with the production order, whether the voltage, control type, connection method of the electric actuator, whether it is an explosion-proof product, and whether it is consistent with the production order, whether the screws of the valve and electric actuator are tightened, whether there are any missing ones)
3. Inspection before packing: Check whether the product quantity, model, voltage, control method, and spare parts are consistent with the production order.
4. Inspection of random inspection products in the processing center: Once in the morning and afternoon every day, take the inspection item list to the processing center and randomly select a processed product from each machine. Find the processing center operator and ask him to measure one by one according to the inspection item list and keep records.
Performance features
1. This valve adopts a three-eccentric sealing structure, with almost no wear on the valve seat and butterfly plate, and has a tighter sealing function as it is closed.
2. The sealing ring is made of stainless steel, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent sealing performance no matter under low or high temperature conditions, and has the characteristics of corrosion resistance and long service life.
3. The sealing surface of the butterfly plate is made of cobalt-based hard alloy surfacing. The sealing surface is corrosion-resistant and has a long service life.
4. This valve has a two-way sealing function. It is not restricted by the flow direction of the medium or affected by the spatial position during installation. It can be installed in any direction.
