【 Q 】 Common problems in the small open degree office of the electric ball valve comprised of place 【 A 】 The reasons for common problems in the electric ball valve small open degree of job site. Although nitrogen sealed valve end into the nitrogen, but when succession into the material tank, storage tank pressure rise, the tank inside the material by nitrogen sealed valve exhaust vent, resolutely to keep the atmosphere of nitrogen pressure force is not too low, if is something self-reliance type valve, breathing trough another water seal up the effect, make the tightly closed circle regularly by the impact of the seat, so tightly closed circle abrasion or cracks, not tight sealing effect. 。 Is through the electric ball valve to drive the stem, stocks move Marine valve core movement, about electric ball valves, relatively simple, break the signal, can according to the manipulation of the plate setting and continued throughout the paper, and determined to be fitted in any position, when selecting pneumatic diaphragm regulating valves, we must first judges selected gas drive is still closed gas, which is the selection of electric ball valve die when the protection of the bearing, if need die valve open technology, pneumatic active closed the position control valve positioner output signal pressure locking in membrane indoor electric ball valves, pressure output signal with the manipulation of the Industrial Valves spring reaction phase equilibrium, electric ball valve valve position determined to be in the wrong direction. Air by propane tanks stored in the air supply to the valve, and then complete the valve or when the die with the position valve fitted to the position, when the fault signal, using electromagnetic valve to the position, however, the electromagnetic valve is an indispensable and locator chain of the whole paper. Seated or transformation of the whole paper can be connected through debugging of pneumatic directional control valve to complete. Another air intake, one-way valve closed, air supply by propane tanks stored in air to supply the electric ball valve, and then complete the valve seated or the whole paper. 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.
