が用いられている。2. Description of the Related Art A three-way valve having a valve body having two inlets and one outlet when mixing hot water from a heat exchanger of a water heater and water and supplying it at an appropriate temperature. With respect to the valve seats that communicate with the two inflow ports provided in the valve body and oppose each other, a valve body provided with a valve that abuts each valve seat is slidably provided in the valve body, When the opening of the valve seat on one side decreases due to the sliding of the valve body, the opening of the valve seat on the other side increases, and the valve body is actuated by a manual lever, cock, etc. Is used.

体内で摺動させたものも用いられている。[0003] Since it is difficult to manually adjust the temperature using the mixing valve as described above due to a change in the temperature of the hot water, a change in the amount of water, etc., it is also performed to automatically adjust the temperature. There is also used a motor that is driven and controlled by detecting the temperature of hot water flowing out of a valve body, and the valve body is slid in the valve body by rotation of the motor.

のも提案されている。On the other hand, there is a limit in the capacity of a heat exchanger of a water heater, and when a large heat exchanger cannot be used, the temperature of tap water flowing in winter is low. Even if the valve on the hot water supply side of the mixing valve is opened to the maximum and the amount of water to be mixed is set to zero, the predetermined temperature may not be reached yet. At this time, in order to raise the temperature to a predetermined temperature, the temperature of the hot water flowing out of the heat exchanger can be raised by reducing the amount of water passing through the heat exchanger. A proportional valve is provided in the flow path, and the amount of water is changed according to the temperature. As another measure, a ball valve having a special hole angle has been proposed as a mixing valve so that the amount of water on the hot water side can be adjusted.

構が複雑になり、その設備費も高価なものとなる。In the above-mentioned conventional apparatus, a proportional valve is provided in the flow path on the side of the water heater to change the amount of water in accordance with the temperature. Since two valves are used, the cost of equipment must be high. Also, using a ball valve with a special hole angle as described above as a valve of the mixing valve,
When the flow rate on the hot water side can be adjusted, the sound of the fluid throttled by this ball valve is loud, generates noise, and it is extremely difficult to adjust the mixing characteristics and flow rate characteristics of the hot water and water. Had the disadvantage that
In order to solve the above-mentioned disadvantage, it is conceivable to increase the flow rate by providing a plurality of fluid conduits in parallel, but in that case, the mechanism becomes complicated and the equipment cost becomes expensive.

When the spindle moves, in the first movement section of the spindle, the first valve is in the first valve seat and the second valve is in the second
Since they move in inverse proportion to each other with respect to the valve seat, the mixing amount of the fluid flowing from the two inlets of the valve body is adjusted. When the spindle moves further after the second valve closes the second valve seat and the first valve completely releases the first valve seat, the first valve is kept in contact with the second valve seat. Moves together with the spindle and moves in a direction to close the third valve seat. Thereby the first
The fluid from the inlet is gradually throttled, and the flow rate is proportionally controlled according to the driving of the motor.

The operation of the mixing proportional valve at that time will be described. When the mixing proportional valve shown in FIG. 1 is used as the valve 23, the first inlet 2 is connected to the pipe 24 from the heat exchanger 22, and the second inlet 4 is connected to the heat exchanger 2.
2 is connected to a pipe 25 that does not pass through, and a pipe 26 that supplies mixed hot water is connected to the outlet 3.

As shown in (1), when supplying the mixed hot and cold water at a predetermined temperature from the state where the motor is driven and stopped so that the spindle 8 is at the highest position, the motor is driven to lower the spindle. As a result, the spindle descends while rotating, the first valve 16 gradually moves away from the first valve seat 5, the second valve 18 gradually moves closer to the second valve seat 6, and passes through the heat exchanger from the first inlet 2. Hot water flows according to the degree of opening of the first valve seat 5, and flows to the outlet through the opened third valve seat 7. On the other hand, the water from the second valve seat 6
It flows according to the opening of the valve seat 6, mixes with the hot water, and is supplied as mixed hot water from the outlet. In this state, as shown in FIG. 5, the amount of water decreases from 100% water and 0% hot water, and the amount of hot water increases in inverse proportion thereto.

とは逆の作動をおこなう。Further, when the motor rotates and the spindle 8 descends, the second valve 18 comes into contact with the second valve seat 6, so that the first valve 16 is fully opened with respect to the first valve seat 5.
Since the second valve 18 is fully closed with respect to the second valve seat 6,
The amount of hot water from the heat exchanger is maximized and the water is shut down in principle. This state is shown in FIG. From this state, when the motor further rotates in the same direction and the spindle 8 descends, the second valve 18 cannot come down because the second valve 18 is in contact with the second valve seat 6. The spring 20 is compressed and only the retaining ring 21 is lowered. At this time, since the first valve 16 is further lowered from the fully opened position of the first valve seat 5, it approaches the third valve seat 7 and starts closing the opening of the third valve seat 7. As a result, the amount of hot water decreases and the amount of water flowing through the heat exchanger decreases, so that the temperature of the hot water coming out of the heat exchanger increases, and the water supplied to the mixing valve is stopped. The temperature of the hot water flowing out of the proportional valve gradually increases. Since the descending amount of the spindle 8 and the amount of hot water flowing through the third valve seat 7 are proportional, they function as a proportional valve here. Thus, the first valve 16 closes the third valve seat 7 with the lowering of the spindle 8, and the supply of hot water is stopped when the first valve comes into contact with the third valve seat 7. This state is shown in FIG. 3, in which the temperature of the hot water flowing out of the mixing proportional valve is the highest immediately before. The forward and reverse rotation of the motor is controlled so as to keep the temperature of the hot water coming out of the outlet 3 constant within this range. When the motor is rotated in the reverse direction from the state shown in FIG. 3, the reverse operation is performed.
