The present invention proposes a flow detection valve with a simple structure suitable for notifying the operation of a sprinkler in a simple sprinkler system by means of a water flow in a pipe.
(従来の技術)
配管内の流体の流動の有無を検出する手段とし

力する構造である。 This on-off valve has a reed switch embedded in a blind plug attached to the bottom of the valve box with a filler such as synthetic resin, and is placed inside the blind plug along with the valve body. An operating rod is loosely inserted into the lower part of the valve body and comes into contact with a spring so that it can move, and a magnet fixed to the lower end of the operating rod is installed inside the guide tube.The valve body is moved by the fluid pressure in the primary chamber. When pushed up and the operating rod and magnet move away from the reed switch, the reed switch is opened and a valve opening signal is output.

弁としての構造は複雑となつている。(Problem to be solved by the invention) In this on-off valve, the operating rod, spring, magnet, reed switch, and other flow detection mechanism members are assembled from the blind stopper side (primary chamber side) at the bottom of the valve body. ,
Valve mechanism members such as the spring for the valve body are assembled from the upper side of the valve body (secondary chamber side), so the assembly and operation adjustment of the flow detection mechanism and valve mechanism are troublesome. The structure of an on-off valve equipped with a detection mechanism is complicated.
また、リードスイツチは、繰返し作動による故
障が発生しやすいものであるが、この開閉弁のリ
ードスイツチは、盲栓に、合成樹脂等の充填材で

そして磁石は、作動杆を遊挿している案内筒に
内装してあるため、上記遊挿部分から流体が案内
筒内に洩れ込む恐れが大きく、流体による磁石の
発銹の恐れがある。 Since the magnet is housed within the guide cylinder into which the operating rod is loosely inserted, there is a strong possibility that fluid will leak into the guide cylinder from the loosely inserted portion, and there is a risk that the magnet will rust due to the fluid.

で面倒となるという問題が、新たに発生する。 Furthermore, if it is attempted to prevent the magnet from rusting, it is necessary to make the insertion part of the operating rod into the guide cylinder watertight with an O-ring or the like. In this case, the sliding resistance of the operating rod becomes extremely large, and a new problem arises in that the adjustment of the elastic pressure of the spring and, by extension, the operation of the valve body becomes extremely complicated and troublesome.
