Electric sealed butterfly valve

Electric sealed butterfly valveIt has the same function as the hydraulic butterfly valve. The commonly used structural forms of regulating valves include straight through single seat valves, straight through double seat valves, sleeve valves, eccentric rotary valves, butterfly valves, fully functional ultra light regulating valves, and ball valves. Based on different usage situations and the characteristics of different structural forms of valves, the structural form of regulating valves should be evaluated from the aspects of regulating performance, applicable temperature, applicable diameter, pressure resistance, applicable medium conditions, cut-off differential pressure, leakage rate, pressure loss, weight, appearance, cost, etc.

Electric sealed butterfly valveFeatures:

1. Electric opening and closing, with arbitrary adjustment, check and cut-off functions. Easy to operate, safe and reliable.

2. This valve can continuously achieve slow opening, fast opening, fast closing, and slow closing actions, and effectively prevent the backflow of the pump outlet medium and the generation of water hammer.

3. Energy saving drive, with the same drive motor as ordinary butterfly valves, can achieve the function of fast closing high-speed small torque and slow closing low-speed large torque.

4. When installed at the pump outlet, this butterfly valve has the common function of a check valve and a gate valve, so one valve can replace two valves, saving installation space and reducing pipeline costs. 5. Low flow resistance. When the valve is fully opened, the flow resistance coefficient does not exceed 0.3, which can save energy and reduce the operating costs of the pipeline.

6. When an accident or power outage occurs, the butterfly valve can be manually operated to control its opening and closing.

Daily maintenance work

1. Attention should be paid to the storage environment of valves, which should be stored in a dry and ventilated room, and the two ends of the passage should be blocked.

2. Valves should be regularly inspected and cleaned of dirt, and rust proof oil should be applied to their surface.

3. After installation, the valve should be regularly inspected to ensure its normal operation.

4. The valve sealing surface should be checked for wear and repaired or replaced according to the situation.

5. Check the trapezoidal thread wear of the valve stem and valve stem nut, whether the packing is outdated or ineffective, and make necessary replacements.

6. Test the sealing performance of D941X-16 rubber sealed electric butterfly valve to ensure its performance.

7. The valve in operation should be intact, and the bolts and threads on the flange and bracket should not be damaged or loose.

8. If the handwheel is lost, it should be promptly equipped and cannot be replaced with an adjustable wrench.
