After using the handwheel on board a institutions, should be restored to the original neutral position. So flameproof products should be according to the explosive dangerous location electrical facilities installation specification requirements of installation. Because the electric control valve installation should pay attention to the following aspects: (in the application 1) Regulator belonging to present instrument for temperature should be - in the background 25 ~ 60 ℃, relative wetting degree 95 one hundred percent or less. After installation, to ensure not to legacy of impurities in the valve body, should also again the valve cleaning, namely pass into the media should make full open valve, lest jam impurities. ( 2) Regulator is ordinary should be straight, special things can heeling conditions, such as the dip Angle is very large or too much weight on the valve when the valve itself should increase support to take care of. At the same time in dismantling the harm upon or scratch flame-proof surface, check after repair to return to the original state of flame-proof requirement. ( 6) Electric control valve electrical local installation should be based on the related electrical facilities construction requirements. Q: the installation of the electric control valve using pay attention to the things of project a: new presets, installation of stem system, in order to ensure that the regulator can normal office while driving, and make the system safe operation, before installing a new valve, shall, first of all, seizing the metal brand mark in the valve is in accordance with preset requirement. At the same time also deal with the following project implementation of adjustment. Regulator in present use, many are often not moved by the regulator itself quality, but the switch section of the Industrial Valves installation caused by inappropriate use, such as background, the installation position and direction pipe is not appropriate or cloudy comprised. If to imposed overhaul section in the original system of valves, except for the above various performing calibration, also deal with stuffing box, and a petition in parts of the old valve tightly closed investigation. Assembly should also be after seizing valve position and the opening of the valve position is directed. ( 4) Regulating Industrial Valves before installation to deal with pipeline cleaning, dispense with dirt and welding slag. ( 3) Install regulator in the pipeline ordinary do not too high above the ground or floor, height is greater than 2 m Marine valve in pipe should try to set up the platform, facilitate the handwheel operation and easy maintenance. Such as the presence of wire saw fit and use SBH type or other six or eight core, outer diameter for & amp; φ; 11. About 3 mm rubber cable installation. ( 7) Reduce the speed of the actuator device after repairing and refueling lubricating oil should be paid attention to, low-speed motor common don't cheer unpick and wash. If it is installed in the open air or high temperature applications, waterproof, should be taken to reduce the temperature treatment method. Where there is the earthquake source to stay away from source or increase the treatment method of the vibration control. 。 At the same time should also be believing, valve installation position whether accord with process requirements. In the use of maintenance, banned in explosive places electricity maintenance and enforcement of the flame-proof surface open pry. The basic error limits; All the schedule deviation; Back to the poor; Dead zone; Leak amount ( In demanding strict field is often implemented) 。 ( 5) In order to make the valve in the event of a failure or maintenance condition can make the production process, then regulator should add by-pass line. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
