、備えたものである。Means for Solving the Problems In order to solve the above problems, the water stop valve of the present invention includes a water passage, a main valve seat in the water passage, and a governor valve seat that is concentric with the main valve seat. The pilot valve comprises a diaphragm main valve provided with a pilot valve seat, which opens and closes the main valve seat and adjusts water pressure, a governor rod attached to the diaphragm main valve, and a pilot valve which opens and closes the pilot valve seat. The diaphragm main valve is opened and closed by opening and closing, and the water pressure is adjusted by the diaphragm main valve, the governor rod, and the governor valve seat provided in the water passage.
作 用
本発明は、上記した構成によって、止水部と水圧調整部
を一体とすることにより、部品の小型コンパクト化を可
能としたものである。Effects The present invention enables miniaturization of parts by integrating the water stop part and the water pressure adjustment part with the above-described configuration.
実施例
以下、本発明の実施例を添付図面にもとづいて説明する
。第１図において、１６は水通路で、主弁座１６ａ１ガ
バナ弁座１６ｂと、パイロット弁座１６ｃを設けである
。１７はダイヤフラム主弁であり、ガバナロッド１８が
取り付けられている。Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings. In FIG. 1, 16 is a water passage provided with a main valve seat 16a, a governor valve seat 16b, and a pilot valve seat 16c. 17 is a diaphragm main valve to which a governor rod 18 is attached.
１９はパイロット弁であり、スプリング２０、押え板２
１によってパイロット弁座１６ｃに押し付けられている
。また、２２は蓋である。19 is a pilot valve, a spring 20, a holding plate 2
1 is pressed against the pilot valve seat 16c. Further, 22 is a lid.
上記構成において、パイロット弁１９を開とすると、水
通路１６の２次室側日に１次側室Ａより水が流れ、２次
室側日と１次側室Ａの圧力差が減少する。そのため水圧
によってダイヤフラム主弁１７が開となる。次に、主弁
座１６ｇを通過し流れる水は、ダイヤフラム主弁１７と
ガバナロッド１８の作用により水の圧力を一定に保つこ
とができる。In the above configuration, when the pilot valve 19 is opened, water flows from the primary chamber A to the secondary chamber side of the water passage 16, and the pressure difference between the secondary chamber side and the primary chamber A decreases. Therefore, the diaphragm main valve 17 is opened by the water pressure. Next, the pressure of the water flowing through the main valve seat 16g can be kept constant by the action of the diaphragm main valve 17 and the governor rod 18.
発明の効果
以上のように本発明の止水弁によれば次の効果が得られ
る。Effects of the Invention As described above, the water stop valve of the present invention provides the following effects.
（１）止水弁と水圧調整部を一体としたため、小型部品
化することができる。(1) Since the water stop valve and the water pressure adjustment part are integrated, they can be made into smaller components.
（２）止水弁と水圧調整部を一体とし、従来の主弁とダ
イヤフラムを一部品としダイヤフラム弁として構成した
ため、部品点数を大幅に低減し、低コストとすることが
できる。(2) Since the water stop valve and the water pressure adjustment part are integrated, and the conventional main valve and diaphragm are made into one part and configured as a diaphragm valve, the number of parts can be significantly reduced and costs can be reduced.
