本考案は管継手を利用して流水等の粘性抵抗に
より複数個の近接スイツチを作動させる流水スイ
ツチに関する。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a flowing water switch that uses a pipe joint to operate a plurality of adjacent switches by the viscous resistance of flowing water.

る。<Prior art> Conventionally, this type of water switch has a guide pin that is fixed perpendicularly to a flow hole having an inlet and an outlet on the left and right sides, and has a hollow part of a cylindrical magnet loosely inserted through it. The viscous resistance causes vertical movement of the magnet to actuate a proximity switch fixed on the guide pin.

なつて、このような流水スイツチの信頼性は希薄
となるものであつた。 However, in the conventional water flow switch as described above, the guide pin is fixed perpendicularly to the flow hole, so the inside of the flow hole is partitioned into a two-stage shape to allow the flow of water to flow vertically. A mold for the joint is required, which tends to cause cavities in the joint, leading to high costs such as requiring leak-proofing treatment.Also, due to the vertical movement of the magnet, the mounting position of the proximity switch linked to the vertical movement of the magnet is There was a drawback that the installation of the pipe fitting body was limited because it was fixed directly above the water flow switch.Furthermore, if several of these proximity switches had to be installed above the water flow switch as necessary, In order for each proximity switch to perform a predetermined operation in response to the operation of the magnet, it is necessary to incorporate various complicated and bulky mechanisms between the magnet and the upper and lower sides of each proximity switch. In addition to the drawback that the number of switches is limited, it is difficult to obtain accurate switch operation due to variations and misadjustments in the parts used, and the vertical movement range of the magnet is limited within the pipe fitting body. This type of water flow switch was unreliable, as weight gain was unavoidable and pressure loss also occurred.

In the flowing water switch according to Utility Model Application No. 54-150879, in order to adjust the operating water amount of the proximity switch,
A system equipped with a water flow adjustment valve has been proposed. Further, in the switch disclosed in Japanese Patent Application Laid-Open No. 48-54476, the operating water amount of the proximity switch is adjusted by sliding the proximity switch in the axial direction of the cylinder.

的大きなものであり、その結果下記の問題を生ず
る。<Problems to be Solved by the Invention> In these conventional water flow switches, only one proximity switch is used, and a signal is emitted only when the flow rate is detected. However, there are cases where it is desired to transmit a plurality of signals corresponding to a plurality of flow rates and open/close a valve according to each flow rate. In this case, it is conceivable to use a plurality of proximity switches. However, proximity switches are relatively large in length, resulting in the following problems.
第１に、小流量の変化で、各スイツチを作動さ
せたい場合、近接スイツチの長さが限界となつて
いる。即ち小流量の変化で各スイツチを作動させ

すれば、各スイツチがぶつかりそれ以上各スイツ
チの間隔を小さくすることができない。結果、近
接スイツチの長さが限界となり小流量の変化での
各スイツチの作動が不可能となつていたものであ
る。 First, when it is desired to operate each switch with a small change in flow rate, the length of the proximity switch is a limit. That is, if each switch is to be operated with a small change in flow rate, the switches must be placed close to each other. However, since the length of the proximity switches is relatively large, if the proximity switches are arranged on the same straight line, the switches will collide with each other, making it impossible to further reduce the distance between the switches. As a result, the length of the proximity switches has reached a limit, making it impossible to operate each switch with small changes in flow rate.
第２に、近接スイツチの長さが限界となり近接
スイツチの付設個数を増やせないという問題があ

ない。結果、近接スイツチの長さが限界となり、
その付設個数を増やすことができない。 Second, there is a problem in that the length of the proximity switch is limited and the number of proximity switches cannot be increased. That is, if a large number of adjacent switches are arranged on the same straight line within a certain length, each switch will collide with each other, making it impossible to arrange a larger number of switches. As a result, the length of the proximity switch becomes a limit,
It is not possible to increase the number of attached devices.

がある。 Third, the proximity switch gets in the way, and there are limits to where the water switch can be installed. When installing a water switch, the proximal switch protruding from the water switch may get in the way due to its relationship with other piping or equipment, and the installation location may have to be changed.

る。<Means for Solving the Problems> Therefore, the present invention provides a pipe fitting main body consisting of a fitting body and a receiving body that conducts the flow hole having an inlet and an outlet at both ends in the longitudinal direction. A magnet, which is pressed against the inlet side by a spring, is fitted so that it can slide freely from the inlet side to the outlet side, and a proximity switch is installed on the outer periphery of the pipe joint body so as to be linked to the movement of the magnet. In the attached water flow switch, the outer circumferential surface of the flow hole at least within the movement range of the magnet forms a cylindrical circumferential surface with a constant diameter in the axial direction, and a plurality of circular belts are fitted into the cylindrical circumferential surface. The axial width of the circular belt is made smaller than the length of the proximity switch, and the proximity switch is attached to each circular belt so as to be lifted from the cylindrical circumferential surface by at least the radial thickness of the belt. The above-mentioned problems are solved by providing a water flow switch characterized in that the switch is attached to a pipe joint body so as to be movable in the axial direction and rotatable through 360 degrees.

る。 To explain the function of the water flow switch as described above, referring to Figures 1 and 2, first, the inlet 3
Running water flows into a. The pressure of the flowing water that has entered the inlet 3a, that is, the viscous resistance of the flowing water, pushes the magnet 7, which is pressed by the spring 8 so as to close the inlet 3a, in the direction of the water flow. At this time, the flowing water flows all at once into the communication hole 1a that communicates the inlet 3a and the outlet 2a, and the flowing water flows through the hole formed in the pin seat 4 between the magnet 7 and the communication hole 1a. 4a to the outlet 2a
is discharged out of the system. At the same time, the magnet 7
The flowing water that continuously flows into the flow hole 1a overcomes the pressing force of the spring 8 all at once due to the viscous resistance, and is guided by the guide pin 5 to the pin seat 4 as shown by arrow A, and flows in the same direction as the flowing water. Moving. That is, the quick movement of the magnet 7 causes the proximity switches 9, 9', 9'' attached to appropriate positions on the outer periphery 1b of the pipe joint body 1 to be activated in sequence accurately. ' and 9'' are, for example, the positions where the magnet 7 moves due to the viscous resistance when the flow rate passing through the flow hole 1a hits the magnet 7 at 3/min, and the position where the magnet 7 moves when the flow rate to the magnet 7 is 6/min. If the magnet 7 is attached to a position where it moves further and a position where the flow rate moves further at 8/min, the movement of the magnet 7 due to the successive increase in flow rate will cause the magnet to move at each of the above predetermined flow rates. Each corresponding proximity switch will be activated. And then,
When the flowing water that continuously flows from the inlet 3a weakens or stops, the pressing force of the spring 8 overcomes the viscous resistance of the flowing water and pushes the magnet 7 toward the inlet 3a. .

Each proximity switch 9, 9', 9'' is controlled by slidable movement in accordance with the direction of water flow from the side.The magnet 7 is formed in a cylindrical shape, so that the flow hole The inner diameter of 1a can be utilized to the maximum extent, the viscous resistance of flowing water can be uniformly received, and at the same time it is not affected by swirls of flowing water during sliding.
