How to wire the electric wafer butterfly valve

by:Sino Valves     2021-03-09
The technical engineer teaches you how to wire the electric wafer butterfly valve? 1. Wiring diagram of the switch type electric butterfly valve with source light indication, there are 5 wires in total, 1, 2, 3 are the control part, 1, 4, 5 are the feedback part 2. The switch type has passive contact type feedback electric butterfly valve wiring In the figure, 1, 2, 3 are the wiring of the control part, 4, 5, and 6 are the passive contact feedback 3, and the switch type electric butterfly valve with opening signal feedback is the wiring diagram. 1, 2, 3 are the control wiring part, 4, 5, and 6 are the feedback part, output resistance value of 0-5K, you can choose 4. AC380V three-phase power electric butterfly valve wiring diagram 5. The electric wafer butterfly valve product has undergone a special baking paint treatment as a whole, which can avoid the appearance of rust on the surface of the product. The internal structure adopts a new and optimized structural design and adopts a double eccentric structure. The difference from traditional butterfly valve products is the electric wafer butterfly valve. It has a tighter and tighter sealing function and excellent sealing performance. The sealing material is matched with stainless steel and rubber, which greatly improves the overall sealing performance of the product and extends the service life of the wafer butterfly valve. Butterfly valve has small size, light weight and reliable performance, especially suitable for transporting clean fluid and gas.   For these two kinds of electric butterfly valves, in addition to the difference in structure, if the parameters are the same, the biggest difference is the different connection methods of the two.  The electric flange type butterfly valve body has its own flange, which is connected with the pipe flange by bolts. The wafer butterfly valve has no flange at both ends of the valve body, and a set of bolts are used to connect with the pipeline flange. The sealing performance of the wafer butterfly valve is worse than that of the flange butterfly valve, but the cost is lower than the electric flange butterfly valve. Each has its own characteristics. When purchasing, choose the installation conditions and choose the corresponding electric flanged butterfly valve or wafer butterfly valve. Before installing the electric wafer butterfly valve, please refer to: 1. Before installation, use air spray to remove foreign objects on the piping, and clean the inner surface of the piping with clean water. 2. Carefully check whether the valve usage is consistent with its performance specifications; (temperature, pressure) 3. Check whether there is any debris on the valve passage and sealing surface, and remove them in time; 4. Install the valve in time after opening the box, and do not loosen the valve at will Any fastening screws or nuts on the upper side; 5. Wafer butterfly valves must use special butterfly valve flanges. 6. The electric butterfly valve can be installed on the pipeline at any angle. It is recommended not to install it upside down for the convenience of maintenance. 7. When installing the butterfly valve flange, it must be ensured that the flange surface and the sealing rubber are aligned, the screws are evenly tightened, and the sealing surface must be intact; if the screw tightening force is uneven, the rubber bumps will block the butterfly plate, or the top Staying on the butterfly plate causes leakage at the valve stem. D971X-16 electric butterfly valve consists of electric actuator and wafer butterfly valve, also called electric wafer butterfly valve, electric soft sealing butterfly valve, electric actuator control voltage AC220V, DC24V, AC380V, switch type, passive contact type, open Signal type, intelligent adjustment type, the butterfly valve is a wafer butterfly valve, cast iron valve body, ductile iron valve plate, stainless steel valve plate, EPDM rubber, tetrafluoro rubber seal, suitable for temperature ≤ 120 ℃ such as food, chemical, petroleum, electric power, The water supply and drainage and gas pipelines of textile and papermaking are used to adjust the flow rate and intercept the medium. Features of electric wafer soft sealing butterfly valve: 1. Novel and reasonable design, unique structure, light weight, and rapid opening and closing. 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 a long service life.
