[0002]

2. Description of the Related Art Conventionally, a hot water heating type heating device heats and generates hot water with a heat source device equipped with an oil burner or a gas burner, and distributes and circulates the hot water to a hot air heater or a floor heating panel. By doing so, it is configured to heat the room. Further, in order to obtain a required heating capacity in the hot air heater or the like, high-temperature water of, for example, about + 80 ° C. is required. Therefore, high-temperature water that satisfies this is generated in the heat source device.

However, hot water suitable for the floor heating panel or the like is low-temperature water of about + 60 ° C. If the high-temperature water is directly supplied from the heat source device to the floor heating panel,

Was. According to this method, the amount of heat flowing into the floor heating panel is reduced, and the average hot water temperature in the floor heating panel is reduced, but the temperature of the hot water flowing into the floor heating panel is still high. The temperature does not drop and the above disadvantages in this area are not solved at all. Conversely, the temperature difference between the outlet portion and the outlet portion increases, resulting in discomfort to the user.

For example, Japanese Patent Laid-Open Publication No. 1-277137 discloses a high-temperature water circuit for circulating a heat source device, and a low-temperature water circuit for circulating hot water whose temperature is reduced by radiating heat in the high-temperature water circuit without passing through the heat source device. There is also a method of flowing the low-temperature water of the low-temperature water circuit to the floor heating panel.However, since the hot-water temperature of the low-temperature water circuit inevitably depends on the load state of the high-temperature water circuit, a plurality of There has been a problem that the temperature of the hot water in the low-temperature water circuit must be managed using a sensor and a complicated control device.

The present invention has been made to solve the above-mentioned conventional technical problem, and supplies hot water to a radiator using low-temperature water such as a floor heating panel using a heat source device that generates high-temperature water. The present invention provides a hot water temperature control valve suitable for a hot water heating device to be heated and a hot water heating device using the same.

Since this can be achieved without using control parts and the like, it is possible to reduce costs and improve durability by simplifying the structure. Further, if the set temperature can be adjusted by adjusting the position of the thermal valve as in claim 2, it is possible to arbitrarily adjust the temperature of the hot water in which the low-temperature water flows into a suitable heat radiating device as described above. It becomes possible and usability is further improved.

The periphery of the large diameter portion 58 is movably in contact with the inner surface of the main body 34 below the step portion 43 via an O-ring 59.

A high-temperature water channel 61 extending from the high-temperature water inlet 32 to the junction 36 is formed in the operating valve seat 56 with the tip of the small-diameter portion 57 of the operating valve seat 56 separated from the valve body 48. The upper and lower end surfaces of the main body 34 are closed by covers 62 and 63, and the cover 63, the operating valve seat 56 and the cover 63 are closed.

An O-ring 72 is also attached between the body and the body 34.

The operation of the above configuration will be described. Heat source device 3
From the header 6, hot water of + 80 ° C. flows into the hot water pipe 17 through the hot water outlet 11. Hot water piping 17
After flowing into the heat exchange tank 22, the hot water flows into the low temperature water inlet 31 of the hot water temperature control valve 24, and the low temperature water channel 53 and the hot water channel 39 in the hot water temperature control valve 24 as described later.
After passing through the vicinity of the temperature sensing portion 46 of the thermal valve 44, it enters the hot water pipe 19 from the hot water outlet 33. Then, it flows into the hot water pipe 27 of the floor heating panel 2 from the inlet end 27A via the hot water pipe 19.

The hot water flowing into the hot water pipe 27 circulates in the floor heating panel 2 to radiate heat and exhibit a heating effect. Then, the hot water pipe 2 of the heat exchanger 16 exits from the outlet end 27B.
1 and flows into the heat exchange tank 22 through the hot water pipe 21. Then, the hot water pipe 17 is placed in the heat exchange tank 22.
After the heat exchange with the hot water pipe 1
8, circulation is performed to return to the header 7 of the heat source device 3.

A part of the high-temperature water flowing into the hot-water pipe 17 flows into the bypass pipe 23, bypasses the heat exchange tank 22, and directly reaches the high-temperature water inlet 32 of the hot-water temperature control valve 24. High temperature water channel 61 in temperature control valve 24
Then, it passes around the temperature sensing portion 46 of the thermal valve 44 through the hot water channel 39 and enters the hot water pipe 19 from the hot water outlet 33. And
It flows into the hot water pipe 27 of the floor heating panel 2 from the inlet end 27A via the hot water pipe 19.

Here, the hot water pipe 21 is connected to the heat exchange tank 2
The warm water entering the inside 2 is low-temperature water (for example, about + 50 ° C.) having a low temperature after radiating heat in the floor heating panel 2. Therefore, the high-temperature water flowing through the hot water pipe 17 is supplied to the heat exchange tank 2.
In the process of passing through the inside 2, heat is exchanged with this low-temperature water, and after the temperature is reduced, it becomes low-temperature water and reaches the hot-water temperature control valve 24.

Next, the operation of the hot water temperature control valve 24 will be described. As described above, the low-temperature water from the hot-water pipe 17 and / or the high-temperature water from the bypass pipe 23 pass around the temperature sensing portion 46 of the thermal valve 44 and affect the temperature. now,
Assuming that the state is as shown in FIG. 3, at this time, FIG.
As shown in the figure, the projections 51 and 52 of the valve element 48 are separated from the projection 39 of the main body 34, and the tip of the small diameter portion 57 of the operating valve seat 56 is in contact with the valve element 48.

In this state, the low-temperature water channel 53 in the main body 34 is opened, the high-temperature water channel 61 is closed, and low-temperature water flows out of the junction 36 through the hot water channel 39 to the hot water pipe 19 as shown by a solid arrow in FIG. ing. At this time, the operating valve seat 56
Corner 67 is in contact with the step 43 of the main body 34 and cannot be raised any further.

In this state, when the temperature of the hot water sensed by the temperature sensing section 46 becomes lower than the set temperature, the thermal valve 44 gradually retracts the cylinder 47 as described above and raises the valve body 48 (FIG. 5). As a result, the ridge 52 approaches the valve seat 42, so that the flow path of the low-temperature water channel 53 is reduced, and the flow rate of low-temperature water (indicated by a solid line arrow in FIG. 5) is reduced.

On the other hand, the operating valve seat 56 has the corner 67 as described above.
The valve body 48 and the small-diameter portion 57 are separated from each other, so that the high-temperature water channel 61 is opened. As a result, the high-temperature water from the bypass pipe 23 reaches the junction 36 as shown by the dashed arrow in FIG. 5, merges with the low-temperature water from the low-temperature water path 53, and flows out to the hot-water pipe 19 via the hot water path 39. Thereby, the hot water piping 2 of the floor heating panel 2
The temperature of the hot water flowing into 7 will rise.

If the temperature of the hot water sensed by the temperature sensing section 46 is still low, the thermal valve 44 further retracts the cylinder 47 and raises the valve body 48 (FIGS. 6 and 7). As a result, the ridge 52 abuts on the valve seat 42, and the low-temperature water channel 53 is closed.

On the other hand, the operating valve seat 56 is
The valve body 48 and the small-diameter portion 57 are further separated since the valve body 48 cannot contact the step portion 43 and cannot be raised. I do. Thus, the temperature of the hot water flowing into the hot water pipe 27 of the floor heating panel 2 via the hot water channel 39 further increases.

When the temperature of the hot water sensed by the temperature sensing section 46 rises from the set temperature in this state, the thermal valve 44 gradually causes the cylinder 47 to protrude, and lowers the valve element 48. Then, as shown in FIG. 4, the valve body 48 is brought into contact with the small diameter portion 57 of the operating valve seat 56 to close the high temperature water channel 61. As a result, the hot water pipe 27 of the floor heating panel 2 passes through the hot water channel 39.
The temperature of the hot water flowing into the tank gradually decreases.

If the temperature of the hot water sensed by the temperature sensing section 46 is still high, the thermal valve 44 further protrudes the cylinder 47 and lowers the valve element 48 (FIG. 8). At this time, since the valve body 48 pushes down the operating valve body 56 against the coil spring 64, the high temperature water channel 61 is kept closed and the ridge 51
Is brought close to the ridge 39 to reduce the flow path of the low-temperature water channel 53. As a result, the flow rate of the low-temperature water flowing into the hot water pipe 27 of the floor heating panel 2 via the hot water channel 39 decreases.
The amount of heat itself supplied to the floor heating panel 2 is reduced.

If the temperature of the hot water sensed by the temperature sensing section 46 is still high, the thermal valve 44 further protrudes the cylinder 47 and lowers the valve element 48 (FIG. 9). Valve body 48
Pushes down the operating valve body 56 further against the coil spring 64, so that the ridge 51 is
9 and the low-temperature water channel 53 is closed. As a result, the hot water flowing into the hot water pipe 27 of the floor heating panel 2 stops, thereby preventing the user from feeling uncomfortable due to an abnormal rise in temperature or causing the floor material to be damaged.

Here, FIGS. 11, 12 and 13 show a state in which the temperature control knob 69 is screwed in and the thermal valve 44 with respect to the main body 34 is screwed.
10 shows the state of the hot water temperature control valve 24 corresponding to FIGS. 3, 6, and 9 when the position is lowered. In this state, unless the temperature of the hot water sensed by the temperature sensing section 46 becomes lower, the hot water temperature control valve 2 is controlled so that the high temperature water channel 61 is not opened.
The characteristics of 4 change.

That is, in this state, the hot water temperature control valve 24 maintains the temperature of the hot water supplied to the floor heating panel 2 at a lower temperature. Then, as shown in FIGS. 11 to 13, the temperature adjustment knob 69 may be turned and screwed into the main body 34.
