Title:
WATER FEED CONTROL METHOD
Document Type and Number:
Japanese Patent JPS5737162
Kind Code:
A
Abstract:
PURPOSE:To make all inlet flow rate control valves well responsive and to enable to close the valves by operating a plurality of inlet flow rate control valves installed in a water supply line to feed water from a higher plate to a lower place with a pressure introduced from a pressure lead pipe installed in parallel to said line through hydraulic responding parts. CONSTITUTION:A water supply line 10 is installed between a water supply part at a higher place and a water receiving part 9 at a lower place. The water supply part 8 is provided with a throttle valve 11. The line 10 is provided with inlet flow rate control valves 12-14 at H1-H3 water head points. Each control valve 12-14 is provided with a water pressure responding member 15 which detects the pressure on the inlet flow side and controls the opening and closing of valve. A lead pressure line 16 is installed in parallel to the line 10. The lead pressure line 16 is connected to the line 10 on the inlet flow side of the valve 12 and also is connected to each pressure responding member 15. When the water pressure responding members 15 limit the water feed by throttling a throttle valve, an upward force acting on the pressure receiving member 39 is reduced and a valve 36 closes a line 34, thereby the water pressure responding members 15 lower a valve body 27 for the control valves 12-14 with a differential pressure area and allow the valve body 27 to contact a valve seat 20.
