AGRICULTURAL WATER SUPPLY SYSTEM AND ITS DRAINAGE METHOD
To provide a water supply system that is economical and energy-efficient, can be implemented at low cost, and can be easily applied to farms without electrical facilities by enabling the reliable and automatic discharge of all residual water.SOLUTION: A branch pipe open/close valve 5... is configured as an open/close function valve in which a valve body part 5v... is displaced by operating an actuator 5h... to open and close a branch pipe Ps.... Inside the valve body part 5v..., a sub-valve mechanism 6 is provided which switches the valve body part 5v... at a closed position Zc to a closed side Zpc at a predetermined water pressure Fw or more in a branch pipe Psi on the upstream side of the valve body part 5v..., and switches the valve body part 5v... at the closed position Zc to an open side Zpo at a pressure less than the predetermined water pressure Fw. After the water supply from a water supply source S is stopped at the time of water drainage, the residual water in a main pipe Pm and the branch pipes Ps... can be drained from a drain valve 3 by switching the drain valve 3 to the open position.SELECTED DRAWING: Figure 1
【課題】 低コストに実施し、経済性や省エネルギー性に優れた給水システムを提供するとともに、全残留水を確実かつ自動で排出可能にし、電気設備が無い農場等にも容易に適用可能にする。【解決手段】 支管開閉弁５…を、操作部５ｈ…の操作により弁体部５ｖ…が変位して支管Ｐｓ…を開閉する開閉機能弁として構成するとともに、弁体部５ｖ…の内部に、この弁体部５ｖ…に対して上流側の支管Ｐｓｉにおける所定の水圧Ｆｗ以上で閉位置Ｚｃの弁体部５ｖ…を閉側Ｚｐｃに切換え、かつ所定の水圧Ｆｗ未満で閉位置Ｚｃの弁体部５ｖ…を開側Ｚｐｏに切換えるサブバルブ機構６を設け、水抜き時に、給水源Ｓからの給水を停止した後、排泥弁３の開ポジションへの切換により、本管Ｐｍ及び複数の支管Ｐｓ…の残留水を排泥弁３から排出可能にする。【選択図】 図１
