Abstract

PURPOSE:To enable flow regulation in second flow path with correspondence to the temperature in a first flow path by connecting the temperature sensitive section arranged in the first flow path to a flow regulation valve arranged in a second flow path. CONSTITUTION:A first fluid A is flowed in through a first inlet 9 of a first flow path 1 and flowed out through a first outlet 10 while a second fluid B is flowed in through a second inlet 17 and flowed out through first and second branch ports 13, 14. Upon temperature rise(drop) of a first fluid A, the sensed temperature 2 will also rise(drip) to project(retract) the piston 20. Consequently, a valve 5 will move to widen(sqeeze) the gap (a) to increase(decrease) the flow of second fluid B to a first branch port 13 while to widen(sqeeze) the gap (b) thus to decrease(increase) the flow of second fluid B to a second branch port 14. the branch flow of the fluid B can be determined by rotating the regulation handle 16 on the basis of the temperature of the first fluid A.

Description

[Detailed description of the invention] [Technical field]

In the present invention, depending on the temperature of one fluid, the temperature of the other fluid B increases.
The present invention relates to a temperature control valve that controls the flow rate ratio in the direction.

[Background technology]

The conventional automatic hot water mixing faucet, the water lower part that controls the temperature of hot water, the part where hot water and water are mixed, and the temperature detection part with the temperature sensing part 2 are directly connected, and the hot water inlet 6 and the water lower part are directly connected to each other. Water or hot water is poured into each of these and mixed, and the mixed water flows directly into the temperature sensing part 2 such as a thermowax type, and the temperature sensor s2 detects the temperature of this mixed water and moves the valve 5. The structure is such that the opening areas of the hot water side and water side channels are changed by the movement of the hot water side and the water side flow path, thereby controlling the mixing ratio of the original hot water and water detected by the temperature sensing section 2. Therefore, such a temperature control valve controls the mixed water itself detected by the temperature sensing section 2, and the fluid flowing into the temperature sensing section 2 and the fluid to be controlled must be the same. It is possible to only mix fluid and low-temperature fluid, and it is also possible to change only the flow rate of water according to the temperature of the temperature sensing part 2, or to branch only the flow path of water to achieve a branching amount of 4119. There was no exception.

[Purpose of the invention]

The temperature control valve of the present invention includes a temperature sensing section 2 disposed in a first flow path 1 through which a first fluid A flows, and a temperature sensing section 2 branched into two directions on the outflow side of a second flow path 3 through which a second fluid B flows. A branch part 4 is provided, and a valve 5 for adjusting the outflow ratio of the second fluid B in two directions is provided in the branch part 4, and this valve 5 is connected to the temperature sensing part 2 to detect the detected temperature. It is characterized in that the valve 5 is moved by the temperature sensing part 2 according to the temperature, and the temperature of the first fluid A flowing through the first flow path 1 is detected by the temperature sensing part 2, and the temperature of the first fluid A flowing through the first flow path 1 is detected. The flow rate (branch amount) of the second fluid B flowing in the second flow path 3 can be adjusted by moving the valve 5 in the second flow path 3 accordingly. It is possible to obtain hot water at a moderate and stable temperature from a stop-type water heater. DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. An embodiment of the present invention is shown in FIGS. 1 and 2. In the casing 8, a first flow path 1 is formed between the first inlet and the first outlet 10, and a temperature-sensing part storage chamber 11 is formed. 17, a first branch port 13, and a second branch port 14 are formed. A temperature sensing part 2 held at the tip of an adjustment screw 15 screwed into the inside and outside of the casing 8 is disposed in the temperature sensing part storage chamber 11 of the first flow path 1. It can be moved by turning an adjustment handle 16 at the end of an adjustment screw 15. On the other hand, a second person 9017
A valve 5 is provided for switching the flow rate of the second fluid B flowing in from the first branch port 1311 and the second branch port 14i11, and this valve 5 is moved by the temperature sensing portion 2; The temperature sensing part is 2gA due to the spring 21.
is biased in the direction of retraction. As shown in FIG. 2, the thermosensing section 2 has a thermowax 18 sealed therein which expands and contracts as the temperature rises and falls, and is inserted into the partition wall 12 via a packing 19 as the thermowax expands and contracts during the day. By sliding the piston 20, the valve 5 beyond it is moved. Thus, the first fluid A is allowed to flow in from the first port 9 of the first channel 1 and the first fluid A is allowed to flow into the first outlet 10
The second fluid B is caused to flow out from the two ports 17 and flow out from the first branch port 13 and the second branch port 14, and the temperature of the first fluid A increases ( descending)
Then, the temperature of the temperature sensing part 2 also increases (decreases) and the piston 20
The valve 5 moves to widen (narrow) the gap A, increasing (reducing) the amount of outflow of the second fluid B to the first branch port 13 side, and narrowing the gap ( The flow rate of the second fluid B to the second branch port 1411 is decreased (increased) by widening the second fluid B. Also, the amount of branching of fluid B depending on the temperature of first fluid A is i! It can be done from 1gk eight dollar endor 16 and I; Next, one method of using this temperature control valve (1) (an application example) will be explained. FIG. 3 shows an example of use for hot water supply in a washbasin unit, etc. That is, connect the city water distribution percentage i'23 through the second person 9017+3 pulp 22, divide it into a second branch, and connect it to the first branch port 13.
and the outlet 26 of the electric hot water@24 are connected to the first inlet 9, and the faucet 27 is connected to the first outlet 10, so that when the valve 22 is turned on, hot water is supplied from the faucet 27. . The first fluid A is a mixture of hot water and water, and the second fluid B is water (city water), and one temperature control valve controls the amount of water supplied to the electric water heater 24. It is now possible to automatically control the temperature of the mixed water sent to the faucet 27. That is, the temperature of the mixed water sent to the faucet 27 increases (T
When the second branch port 14 is narrowed by the temperature sensor 2 (
), the amount of water injected into the electric water heater 24 decreases (increases), and accordingly, the amount of water sent from the electric water heater 24 to the first flow path 1 decreases (increases). 1
3 is opened (squeezed) and the amount of water sent from the first branch port 13 to the first channel 1 increases (decreases), and as a result, the faucet 27
The hot water sent to the electric water heater 24 is controlled in a 7-pocket manner to maintain a constant temperature, and only the amount of water used is always sent to the electric water heater 24. Moreover, since the electric water heater 24 is controlled at the entrance side, there is an advantage that no pressure is applied to the electric water heater 24. What is shown in FIG. 4 is another example of the present invention, in which the casing 8

The hot water and the water are mixed at the bottom of the core 28. The inflow amount of hot water is adjusted by moving the core 28 up and down. Furthermore, the one shown in tIS5 and FIG. 6 is still another example of the present invention, in which the temperature control valve of the type shown in FIG. 4, the opening/closing valve 22, and the faucet 27 are integrally formed. be. Furthermore, the one shown in FIG. 7 is still another example of the present invention, in which a temperature control valve, a valve 22, and a faucet 27 are integrally formed as in the above embodiment, but the valve 22 is of a switching type. When the handle 32 is reversed, the water supply port 3
Water can be supplied from 1 and when the handle 32 is returned to its original position, the faucet 27
The temperature-sensing section 2 is not limited to one using thermowax 18 as described above, but may also be one using bimetal. If either the second branch port 13 or the second branch port 14 is left open, it can also be used to adjust the flow rate of the second fluid B.
