maintenance and installation of electric butterfly valve
release time:2018/9/23
maintenance details of electric butterfly valve:
1, when installing, the electric butterfly valve should be stopped at the closed position.
2, the opening position should be determined according to the rotation angle of the electric butterfly valve plate.
3. butterfly valve with bypass valve should open bypass valve before opening.
4, should be installed according to the manufacturer's installation instructions, the weight of the butterfly valve should be set up a solid foundation.
daily maintenance of electric butterfly valve is very important, we should make a maintenance plan, according to the plan strictly implemented.
install
1. installation position, height, inlet and outlet direction must meet the design requirements, pay attention to the direction of media flow should be consistent with the direction of the arrow marked by the electric butterfly valve body, the connection should be firmly and tightly.
2, electric butterfly valve must be checked before appearance. the nameplate of valve should conform to the current national standard. for valves whose working pressure is greater than 1.0 mpa and which cut off the main pipe, strength and tightness tests should be carried out before installation, and the valves should be used only after they are qualified. in strength test, the test pressure is 1.5 times of the nominal pressure and the duration is not less than 5 minutes. the valve shell and packing should be qualified without leakage.
electric butterfly valve installation and maintenance should pay attention to the following matters:
1. when installing, the pneumatic butterfly valve must be in the closed position.
2, the opening position should be determined according to the rotation angle of the pneumatic butterfly valve plate.
3. butterfly valve with bypass valve should open bypass valve before opening.
4, should be installed according to the manufacturer's installation instructions, the weight of the butterfly valve should be set up a solid foundation.
