Abstract
PURPOSE: To greatly facilitate automatic pumping, by providing a starting valve capable of instantaneously closing a drain port which is provided at a water hammer pressure production region and communicates with the outside and by automatically and quickly opening and closing a drain valve to cause water hammer pressure.
CONSTITUTION: The starting drain port 13, which communicates with the outside, is opened into a valve chamber 5, on which the water hammer pressure acts. A butterfly valve 6, which is opened and closed by rotation centering a stem 14, is provided in the center of the drain port 13. A handle 15 is provided to rotate the butterfly valve 6. This valve is so formed that water pressure on the right half part of the valve as to the stem 14 is slightly higher than that on the left half part. As a result, a very weak force is used to open and close the butterfly valve 6 to automatically and quickly open and close the drain valve 8. The water hammer pressure is thus caused. Therefore, the automatic pumping operation is greatly facilitated.
