share electric stainless steel valve switch position adjustment result

adjust electric stainless steel valves should be in accordance with the requirements of the adjustment of each manufacturer have to manually close the valve to the full closed position or full open position. If according to the requirements of large diameter artificial closed gate valve open time spent much, also very laborious. But what if you know the adjustable valve stem tooth pitch, the adjustment electric gate valve is very convenient.

domestic valve diameter in DN400 - now DN600 gate the pole tooth is apart from the general to ram; DN600 caliber valve stem teeth from above average 10 for ram. The gate valve manufacturers if possible asked stem tooth pitch. After adjusting valve electric actuator, if know in advance the gate location, such as know the gate valve is in full close position, first adjust the full closed position.

first used manual open gate valve to the direction of some, such as the valve rod rotation or half a circle a circle. Then press the open button to power. At this time can be adjusted first gate valve stroke control mechanism, transferred to the fully closed position, full close position after the adjustment, gate valve can be adjusted by the full open position.

when in open electric stainless steel valves, count gate valve stem rotation laps will know that whether to full open position. Five laps. Clicked open valve button at this point count to 63 times the valve to the fully open position, adjust stroke of valve electric device controller, the micro switch action can full open position. Since electric gate valve can be closed, open check it again, adjust the end. If the electric gate valve in open position before adjustment, you should adjust the position of the open first steps as described above.

electric stainless steel valve adjusted notice:

1. Electric stainless steel valves after using for a year, to check a torque limit institutions of the adjusting nut set screws have you loose or fall off. Special Industrial Valves electric actuator, electric valve in use the gate valve by Industrial Valves plate at the bottom of the upper bursting or fixed electric device by stiffened plates join crack. Why have a torque limit institutions, a moment without action, don't cut off the power supply, the reason is that the torque limit institution in come out of the adjusting nut loose tight set screw for adjusting nut tightening spring over a long period of time, until killed the spring, lose torque limit institutions, no protection, electric gate Industrial Valves damage accident. So a set screws should be inspected every year ever fall off, if the mobility to timely to tighten the set screw, fall off and find out the reason and reinforcement.

2。 Manual a electric switch handle requirements of mechanical flexible, flipping freely, when to manually, make sure to cut off the power supply, there was an accident in order to avoid failure.

3。 The gate valves, rarely for a long time to switch on a regular basis, to guarantee the normal work of the use of ( Preferably once every march rotation) 。
