湯タンク内の温水までも廃棄する結果となり、利
用が極度に制限される点にある。 The weak point of solar water heaters is that during the cold season, the hot water pipes and water supply pipes must be drained to avoid damage due to freezing, and as a result, even the hot water in the hot water storage tank is drained. This results in the product being discarded, and its use is extremely limited.

弁が作動し、給湯が中断されるうらみがあつた。 However, the water supply pressure to the water storage tank may become weak for some reason, and if you use another tap in such a case, the water supply pressure will drop even further.
I was worried that the valve would activate and the hot water supply would be interrupted.
そこでこの発明は、給湯給水を停止して排水時

A valve 12 is fixed to the left end of the valve shaft 11 to open and close the hot water supply port connection port 2. Further, a drive plate 13 for opening and closing the hollow portion of the valve bearing 5 is fixed to the right end portion 11'. This drive plate 13
is constantly pressurized toward the float chamber 10 by a spring 14 housed in the hollow portion. Note that 15 is a diaphragm, and 16 is an intake/exhaust port.

Since the float 17 is supported by a support shaft 19 fixed to the float outdoor shell 7 in a horizontal direction perpendicular to the float chamber 10, the float 17 is rotatable about the support shaft 19 within the float chamber 10. Further, an upper blade 20 and a lower blade 21 are protruded above and below the bulge 17' of the float 17, which has an arcuate longitudinal section.

The valve 12 contacts the protruding portion 18 of the float coaxially to open the hot water supply port connection port 2, and the lower blade 2
1 is configured to abut against the water flow control plate 22.
次に、この発明の作動効果について述べる。 Next, the operational effects of this invention will be described.

２を開き、給湯が可能になる。 Now, as shown in FIG. 3, the water supply is stopped and the water supply is started from the state where the hot water supply pipe 24 and the water supply pipe 25 are drained. The pressure water flowing into the float chamber 10 from the water supply pipe connection port 9 mainly passes between the bulge 7' of the float chamber outer shell 7 and the bulge 17' of the float 17 by the water flow control plate 22. Push the upper blade 20 upward and exit to the water storage tank piping connection port 8. The pressure water that has flowed into the float chamber 10 pushes the drive plate 13 to the left, that is, toward the main body 1 against the pressure of the spring 14, so that it instantly
The valve shaft 11 moves to the left, and the valve 12 opens the hot water supply port connection port 2 connected to the hot water supply port 28 of the solar water heater 27, thereby making hot water supply possible.

の給水圧が、何らかの原因で減少しても、弁軸１
１は固定されたままなので、給湯が可能である。 Also, due to the buoyancy of the float 17 and the force applied to the upper blade 20, the float 17 rotates counterclockwise about the support shaft 19, so that the protrusion 18 and the right end portion 11' of the valve shaft coaxially contact each other. At the same time, the lower blade 21 also comes into contact with the water flow control plate 22, so that the valve stem 11 is fixed (FIG. 2). Even if the water supply pressure in the float chamber 10 decreases for some reason, the valve stem 1
1 remains fixed, so hot water can be supplied.
又、給水を停止しても、弁軸１１は固定されて
いるので、後述の手元弁装置の操作により、オー
バーフロー、或いはロツト何れの給湯も可能であ
る。 Furthermore, even when water supply is stopped, since the valve stem 11 is fixed, either overflow or lot water supply is possible by operating the hand valve device, which will be described later.

出部１８は、弁軸右端部１１′からはずれる。 On the other hand, from the state shown in FIG. 2, if the hot water supply is stopped and drainage from the hot water supply pipes 24 and 25 is started, the water flowing down from the water storage tank pipe 26 will mainly flow through the float bulge 17' and the float. The upper blade 20 is pushed downward as the water passes through the outdoor shell bulge 7' and exits to the water supply pipe connection port 9 to be drained. At the same time, the water in the protrusion 18 in the float chamber 10 pushes the protrusion downward and drains into the water drain hole 2 of the water control plate.
3 to the water supply pipe connection port 9. Furthermore, if the water in the float chamber 10 decreases, the center of gravity of the float 17 is on the right side of the support shaft 19, so the float 17
tries to rotate clockwise due to its own weight. Therefore, the float 17 rotates clockwise, and the protrusion 18 is removed from the right end 11' of the valve shaft.
一方、フロート室１０内の水圧が急激に減少す
るので、スプリング１４の力により駆動板１３は
右方に押され、弁１２は瞬時に給湯口接続口２を
閉塞し、給湯管２４内の排水が可能となり、貯湯
タンク内の温水は無駄に排出されることがない。 On the other hand, since the water pressure in the float chamber 10 suddenly decreases, the drive plate 13 is pushed to the right by the force of the spring 14, the valve 12 instantly closes the hot water supply port connection port 2, and the water in the hot water pipe 24 is drained. This makes it possible to prevent the hot water in the hot water storage tank from being discharged unnecessarily.
なお、ボール弁装置４は、給湯時には水圧によ
り閉じ、排水時には開いて排水を促すものであ
る。 The ball valve device 4 is closed by water pressure when supplying hot water, and opens when discharging water to promote drainage.
この切替弁装置を、手元切替弁装置と併用すれ

手元切替弁装置の切替操作で簡単に行えて極めて
便利である。 If this switching valve device is used in conjunction with a hand-held switching valve device, hot water supply and stop, hot water supply pipes, and water supply pipe drainage can be controlled.
It is extremely convenient and can be easily performed by switching the switching valve device at hand.

This hand switching valve device will be briefly described with reference to FIG. 4. 29 is a hand switching valve device, and the water supply pipe connection port 3
0, a set of connection ports consisting of a water faucet pipe connection port 31 and a drain pipe connection port 32, a set of connection ports consisting of a hot water supply pipe connection port 33, a hot water supply faucet pipe connection port 34, and a drain pipe connection port 35; It also has a reduced pressure water pipe connection port 36 and a bypass pipe 37 that connects the reduced pressure water pipe connection port 36 and the hot water tap pipe connection port 34 .

ラ給水の操作が可能である。 Therefore, by rotating the handle 38 by 90 degrees, the internal rotary valve can be switched, supplying hot water to the hot water faucet, supplying water to the water storage tank, and closing the bypass pipe 37. 24, it is possible to operate the boiler water supply by draining the water supply pipe 25 and opening the bypass pipe 37.

上せしめるものである。 As explained above, the switching valve device of the present invention not only drains hot water pipes and water supply pipes without wasting hot water in the hot water storage tank during the cold season, but also allows water supply to be stopped and water supply pressure to be reduced. It is possible to supply hot water even in the case of a decrease in solar water heaters, which greatly improves the utilization efficiency of solar water heaters.
