れているため、操作が大変面倒であつた。 In the case of the above, not only is it not possible to adjust the desired pressure and flow rate with a single valve housing, but it is also troublesome to combine orifices of different diameters depending on the desired pressure and flow rate. In addition to the complicated assembly process of preparing multiple orifices and attaching them to each valve casing, the number of parts increases, making it troublesome to manage parts.The equipment also becomes larger, and there are multiple handles for adjusting pressure and flow rate. Since there are multiple units, operation is very troublesome.

A restrictor is installed at a valve port provided in the middle of the flow path of the pipe body that allows a normal flow rate, and is capable of opening and closing the valve port and allowing a required limited amount of water to pass through in the same direction while the valve is closed. By matching the switching valve body inside the valve, it is possible to freely supply all or a limited amount of water in the same direction despite the simple structure, making it possible to supply hot water at a sufficiently high temperature even in winter. be.

る。(Technical means for solving the problem) The technical means taken by the present invention to solve the above problem is to connect one end of the pipe body to the water supply pipe, and connect the other end to the gas water heater. (In this case, a temperature sensor is installed at the outlet of the gas instantaneous water heater, and this temperature sensor detects the outlet temperature and electrically controls gas combustion to automatically supply hot water at the desired temperature.) A connecting pipe or pipe joint for water supply piping that connects faucets that supply water to A valve port is provided, and a switching valve body supported by a valve support portion is attached to a valve stem attached to a threaded port concentric with the valve port, and the switching valve body is separately provided. By installing a throttle valve and a flow control ring that are connected in advance, in winter when the temperature of tap water drops, by communicating the through hole of the switching valve body and the valve opening, the required amount of restriction can be reduced. This allows water to flow in the same direction.

する。(Function) In the winter when the water temperature is low, the valve opening of the pipe body and the passage of the switching valve body are communicated with each other by operating the knob.
High-temperature hot water is released from the gas water heater with a margin that greatly restricts the flow rate from the valve port, and in the summer, the knob is operated in the direction of opening the valve to pull the passage hole of the switching valve body away from the valve port. This provides normal, unrestricted flow.

いる異物を捕捉するように配置する。 The flow restriction ring 6 separately provided in FIGS. 3 and 4 A to B is made of synthetic resin and has a ring shape, and has a seat 8 with a large inner diameter into which a throttle valve 7 (described later) is fitted on one side, and a seat 8 with a smaller diameter than the seat 8. The valve is formed into a substantially dish-shaped shape with a throttle opening 9 that restricts the flow rate when the valve is closed. The throttle valve 7
A wheel-shaped disc part 11 is formed on one surface of a synthetic resin and has a plurality of through holes 10 with an outer diameter that can fit into the seat 8, and the other surface of the disc part 11 is provided with a saw blade. The outer diameter of the convex surface is slightly larger than the inner diameter of the aperture opening 9, and the diameter of the circumference of the groove bottom of the recess is slightly smaller than the inner diameter of the aperture opening 9. A diaphragm guide part 12 is provided protrudingly. The valve stem 13 has a male threaded portion 14, a seal portion 15, and a valve support portion 16 arranged in the axial direction, and the valve support portion 1
6 has a through hole 10' inside and a male threaded part 14' on the circumferential surface, and the male threaded part 14' has a through hole 10", a valve chamber 17 concentric with the through hole 10", and the male threaded part 14'. A switching valve body 19 having a female threaded portion 18 corresponding to the above is detachably mounted, and the flow control ring 6 and the throttle valve 7 are assembled in advance into the switching valve body 19 with an O-ring 20 interposed therebetween. . The valve stem 13 has a separately provided plug 21 attached to its male threaded portion 14,
The plug 21 is removably screwed into the threaded opening 5 of the pipe body 1 through the female threaded portion 18', and is connected to the through hole 10'' of the switching valve body 19 and the valve opening of the pipe body 1, as shown in FIG. The strainer 22 is removably inserted into the chamber 23 surrounded by the partition wall 4 through a plug 21', so that the strainer 22 introduces fluid into the interior and then passes the fluid through the mesh to the outside. The arrangement is such that foreign matter mixed in the fluid is captured while the fluid is flowing out to the valve port 3 side.

のように流路２を上昇して水栓類に供給される。 Now, when the water pipe and the faucet leading to the gas water heater are connected via the pipe main body 1 for limited water flow in winter, the fluid enters the flow path 2 from the arrow P side shown in Fig. 1. After passing straight into the strainer 22, it advances to the chamber 23 through the mesh of the strainer 22, and passes through the valve port 3 communicating with the chamber 23 and the switching valve body 19 blocking the valve port 3. It rushes into the hole 10'' as shown in Fig. 2. At this time, between the through hole 10'' and the same 10',
Since almost the entire surface is blocked by the throttle guide part 12 of the throttle valve 7, the fluid can flow through the throttle guide part 12.
The flow passes through the sawtooth-shaped pores narrowed by the orifice 9 of the flow control ring 6 on the surrounding uneven circumferential surface, and passes through these with the flow rate being significantly restricted. 16 through hole 10' and arrow P 2 in Fig. 2.
The water rises through the flow path 2 and is supplied to faucets.

ができる。 By supplying water to the gas water heater while restricting the flow rate in this manner, hot water can be obtained from the gas water heater at a high temperature even in the winter when the water temperature is low. In addition, when the water temperature is high such as in summer, the knob 24 of the valve stem 13 is operated in one motion in the valve opening direction, and the through hole 10'' of the switching valve body 19 is pulled away from the valve port 3 to open the valve. This makes it possible to easily supply fluid at a normal flow rate.

温の出湯を可能にできる。(1) The water supply source and the faucet that supplies water to the gas water heater are connected through the pipe body, and the pipe body is equipped with a switching valve body having a throttle valve and a flow control ring, so that tap water is In the summer when the temperature is high, the valve port is left fully open to supply fluid at the normal flow rate, and in the winter when the temperature of tap water drops, the valve port is simply switched to the closed state using the switching valve body. With a simple operation, the amount of water supplied to the gas water heater can be restricted to an appropriate amount, allowing the gas water heater to provide hot water at a high temperature in the winter.
