should provide appropriate working speed. The change of industrial process speed is relatively fast. Coordinate to ensure that the industrial production process, in general, I hope the valve run faster. Especially in the process of loading and unloading, the valve of quick action is very important to ensure the safety of equipment. However, when the running speed of valve, valve opening and closing time is too short, a talent impact in the pipeline. This is absolutely can guarantee safe operation. Should be able to accommodate the total number of turns of valve. The entire valve stroke the total rotation with the valve open height and stem thread pitch. The relationship between them is the main gas valve rotating coefficient m. Manual operation of the valve should be installed in the valve stem is the most basic operating at the top of the handwheel. The personnel on duty on its own strength through the handwheel valve operation. Detection should ensure the valve required schedule for non-mandatory seal valves ( Automatic seal) To opening and closing of the valve components in the specified location to stop when close the valve. At this point, if the valve opening and closing a stroke is not enough, will cause the valve leakage, the journey is too big, is in danger of damage valve parts. As for the valve in the open position, and almost all types of valves are required part of valve opening and closing in the position of the stop. If the valve opening and closing a trip is too large, the valve stem is stuck, communication will be damaged. If the schedule is too small, valve of flow section. Insufficient valve discharge will not only increase the resistance of valve 9 times, corrosion will open/close valve parts. For electric actuator, valves in operation process can be accurate to stop at any specified position. In the case of a release, the stop position error should not exceed 0 full valve stroke. 5%. In the stroke control wedge gate valve closed position, the ice to the closed position to demand higher.
