オリフィス等で構成された流量調整弁を組込む等の対策
がとられているけれども、このような対策では、流量調
整弁の組込のために設備費用が割高となっている。As is well known, in the water supply system,
Ball valve-type water stop valves are used to deal with water pipe heating accidents, but in recent years, due to the diversification of water pipe systems and water conservation, even if the upstream pressure changes, the downstream There is an increasing demand for keeping the flow rate on the side substantially constant. Conventionally,
In order to meet these demands, measures have been taken such as incorporating a flow rate regulating valve consisting of a variable orifice etc. on the downstream side of the water stop valve. Therefore, equipment costs are high.

提案するものである。In order to solve the conventional problems as described above, the present invention aims to obtain a ball valve type fluid valve having a flow rate adjustment function. In a fluid valve that opens and closes the ball valve from the outside using a spindle connected to the ball valve, the ball valve is provided with a passage having a larger cross-sectional area on the upstream side than on the downstream side, and the same flow We propose that a guide rod be supported at the center of the channel, a valve body pushed upstream by a spring be movably supported by the guide rod, and the flow rate be adjusted by the position of the valve body receiving upstream pressure. It is something.
以下、図面にろいて本発明の実施例の詳細を説明する。Hereinafter, details of embodiments of the present invention will be explained with reference to the drawings.

有している。It consists of an IC. That is, the plug screw 1b is connected to the upstream side of the fluid pipe, and the plug screw 1c is connected to the downstream side of the fluid pipe, and a seal ring on which the ball valve 2 is seated is attached to the inner end of the plug screw 1b. 3.4 respectively.

閉できる。Further, the sleeve 1a is formed with a diametrical hole 5, in which a spindle 7 having a protrusion 7a connected to a slot 6 of the ball valve 2 is rotatably positioned. An external operating handle 8 is attached to the outer end 7bK of the spindle 7 with a nut 9, so that the ball valve 2 can be opened and closed by manually operating the external operating handle 8.

ａに挿入される。A passage 10 is penetrated through the inside of the ball valve 2 and can communicate between the plug screw 1b and the plug screw IC. The cross-sectional area of the flow path 10 is larger on the upstream side than on the downstream side, and the flow path 10 is placed inside the upstream side facing toward the screw 1b.
It is located inside the pipe and is pressed toward the upstream side by a spring 12. That is, the support ring 13 screwed onto the outlet end of the ball valve 2 has a plurality of lips 1 in the centripetal direction.
3a is integrally molded, and the tip of the guide rod 14 supported at the center of the flow path by the rib 13a is connected to the center hole 11 of the valve body 11.

以上の労、明から明らかかように、本発明の流体弁にお

ばね工２を押縮めて弁体１１が右方に参勤するので、流
路面積が狭くなり、また、流体弁の上流側の圧力が低く
なると、弁体１１が左方に移動するので、流路面積が広
がるので、下流側の流計を略一定に保つことができる。As is clear from the above efforts, in the fluid valve of the present invention, when the pressure upstream of the fluid valve /Ill becomes low,
When the spring 2 is compressed, the valve body 11 moves to the right, which narrows the flow path area. Also, when the pressure on the upstream side of the fluid valve decreases, the valve body 11 moves to the left, reducing the flow. Since the road area is expanded, the flow meter on the downstream side can be kept approximately constant.
勿論、本発明による流体弁は、従来の可変オリフィス型
の流計調整弁に比較してはるかに耐久性に富む構造であ
る。Of course, the fluid valve of the present invention is of much more durable construction than conventional variable orifice type flow metering valves.

空間的に制約のある場所への組込みも容易となる。According to the present invention, the construction cost is much lower than the conventional method in which a flow meter adjustment valve separate from the fluid valve is incorporated into the pipe, and the plastering and circumference adjustment is possible. Since the inside of the ball valve is used as the space for incorporating the valve, the overall size can be reduced.
It can also be easily installed in locations with spatial restrictions.
