Electric butterfly valve belongs to electric valve and electric regulating valve in a variety. Electric butterfly valve connection mode is mainly: flange type and wafer type; the seal of electric butterfly valve are : rubber seal and metal seal. Electric butterfly valve through the power signal to control the switch of the butterfly valve. The product can be used as cutoff valves, control valves and check valves for piping systems. Equipped with manual control device, once the power failure, it can temporarily use manual operation, and it will not affect daily use

Washing machinery is the basic work of equipment maintenance, which must be institutionalized and standardized. For the regular maintenance work of equipment, work quota and material consumption quota should be established to enrich the people's machinery, and the assessment should be carried out according to the quota. The regular maintenance of equipment should be included in the assessment content of workshop contract responsibility system. Regular inspection of equipment is a planned preventive inspection of the mechanical industry. In addition to human and earth senses, there are also certain inspection tools and instruments, which are carried out according to the regular inspection card. Regular inspection is also called regular spot inspection by mechanical drawing software.

The accuracy of the mechanical equipment should also be checked to determine the actual accuracy of the equipment.

1. Technicians must know about the working condition of the electric butterfly valve on that day

2. Check whether the electric butterfly valve is corroded by the medium

3. Check the electric butterfly valve for noise

4. Check the sealing performance of the electric butterfly valve

5. Check the electric butterfly valve for leakage 

6. Conduct regular daily cleaning of the electric butterfly valve

7. Ensure that there is no leakage the sealing performance of the electric butterfly valve

The electric butterfly valve should be checked every day, and the regular check of the electric butterfly valve should have different check cycles. And it should have high efficiency strainer electric butterfly valve flow characteristics test. Regular calibration requires relevant test equipment and instruments, as well as replacement parts. Electric butterfly valves can usually be commissioned to be completed by manufacturers. Regular maintenance and predictive maintenance are the maintenance before the failure of the regulator. Usually, the daily maintenance of air filter electric butterfly valve is carried out by instrument maintenance personnel, and the regular maintenance of oil-water separator is carried out by manufacturing technicians. The predictive maintenance of the sterilizing filter is based on the analysis results of the predictive maintenance, which requires the maintenance personnel to make a targeted maintenance of the relevant regulating valve components.
