る。However, since the solenoid valve opens and closes the valve by electrical control, a dedicated electric circuit must be assembled to use this, and the mechanism is complicated. Not only that, but there was a problem that the cost was high. In addition, there is a problem that the mechanical opening and closing of the valve by electricity cannot be easily performed because the frequency of failure increases as the frequency of opening and closing increases and the structure is complicated. The present invention has been developed in view of the problems of the solenoid valve described above, and provides a flow rate switching valve that has a simple structure, durability, and can be easily repaired without using an electric system.

ある。In particular, in the process of circulating hot water in the bathtub,
The present invention provides a flow rate switching valve suitable for a piping device that can heat and purify and simultaneously eject fine bubbles without stopping this circulation. Such a piping device is composed of a main pipe that circulates hot water for heating and purification, and a sub pipe that branches off from the middle of the main pipe that mixes and ejects fine bubbles. Then, in order to fill the fine bubbles that have been jetted into the bathtub without extinguishing them, it is necessary to reduce the flow rate of the main pipe when the fine bubbles are jetted and circulate them. The present invention has been made to achieve such an object.

る。Therefore, in the present invention, a branch pipe from a parallel pipe is connected to the valve chamber of a flow rate switching valve attached to the main pipe, and while flowing the fluid to the main pipe, the fluid also flows to the parallel pipe. The flow rate of the main pipe can be switched by pressing the diaphragm of the valve chamber by the pressure of the fluid in the parallel pipes. The gist of the present invention is to provide a valve chamber that is orthogonal to the flow passage in the valve body, and arrange a diaphragm made of a bowl-shaped elastic body on the flow passage side of the valve chamber so that the flow is opposite to the diaphragm. An orifice is installed in the passage, and a flow reduction plate with an arcuate side that matches the curvature of the diaphragm is fitted.The flow path in the normal state is the gap between the orifice and the arcuate side and the diaphragm, and the pressure fluid enters the valve chamber. When a pressure is applied to the diaphragm, the diaphragm comes into close contact with the arcuate side of the flow reduction plate and closes it so that only the orifice serves as a flow path.

構成してもよい。The flow passage 11 of the valve body 10 has internal threads 11 at both ends.
It is composed of a large-diameter passage 111 formed by cutting a and a small-diameter passage 112 communicating with the central valve chamber 12, and the valve chamber 12 communicates with the small-diameter passage 112. Also, the diaphragm 14 can be installed inside. A female screw 12a is formed on the inner surface from the step 121 to the open end of the valve chamber 12. A recess 112 is formed at a position orthogonal to the flow direction of the small diameter passage 112 of the valve body 10.
a is provided so that the flow reduction plate 15 can be fitted and fixed. The diaphragm pressing bush 13 has a male screw 13a on the outer periphery screwed into the female screw 12a of the valve chamber 12 to press and fix the peripheral edge of the diaphragm 14 made of a rubber or plastic elastic body of a bowl type to the step 121. A female screw 13b is provided on the inner circumference of the bush 13 so that the branch pipe 3 can be connected. The diaphragm 14 is sandwiched between the step portion 121 and the bush 13 so that the valve chamber 1
2 and the flow path 11 are watertightly divided. Further, since the diaphragm 14 is sandwiched between the screw grooves of the bush 13 and fixed, water leakage from the valve chamber 12 and the flow passage 11 is completely prevented. The flow reduction plate 15 is formed with a circular orifice 15a and is provided with an arcuate side 15b that matches the curvature of the bowl-shaped projection of the diaphragm 14, and the recess 112a is formed so as to block the small diameter passage 112.
Insert and fix. Although not shown, when the elasticity of the diaphragm 14 is high, it is not necessary to form the diaphragm 14 into a bowl-shaped projection and form the arcuate side edge on the flow reduction plate 15.
In short, the diaphragm 14 reduces the flow reduction plate 15 by the pressure of the fluid.
The diaphragm 14 and the flow reduction plate 15 may have any shape as long as they are in close contact with each other and completely separate the valve chamber 12 and the flow path 11.

小して流量が減少することになる。The flow rate switching valve 1 having such a structure is connected by a piping pipe 2 so that a constant flow rate can be passed by a pump, and a branch pipe 3 from another piping pipe 2 is passed through a valve chamber 12.
Is connected to the diaphragm pressing bush 13 so that the fluid flows in. Therefore, the flow rate switching valve 1 will flow between the orifice 15a, the diaphragm 14 and the arcuate side 15b when a constant flow rate is supplied by a pump, but the fluid from the branch pipe 3 from another pipe 2 Is the valve chamber 1
When supplied to 2, the diaphragm 14 is pressed against the arc-shaped side 15b of the flow reduction plate 15 to close it, and the fluid flows only from the orifice 15a. That is, the fluid passage port is reduced and the flow rate is reduced.
