Description

[Detailed Description of the Invention] The present invention relates to an operating valve for a hot water supply circuit using a solar water heater and a boiler.

Conventionally, as a typical structure of this type of operating valve for hot water supply circuits, the Utility Model Publication Act 1987-1 shown in Fig. 9 has been used.
There is one described in Publication No. 44290. To explain the one in Fig. 9, the water supply chamber 5 communicating with the water conduit
1. A mixing chamber 53 that communicates with the water supply chamber 51 through a water outlet 52; a water pumping chamber 55 that also communicates with the water supply chamber 51 through a water pumping outlet 54; a first hot water outlet 56 through which hot water from the solar water heater flows into the mixing chamber 53; The hot water from the boiler flows into the first hot water supply chamber 57, which communicates with the mixing chamber 53, and the second
A second hot water supply chamber 59 that communicates with the hot water outlet 58 is formed in the main body 60, and the water outlet 52 has a water outlet 61, the water pumping port 54 has a water pump, and the first hot water outlet 56 has a first hot water tap and a second hot water outlet. Reference numeral 58 denotes second hot water taps 62, which are provided so as to be openable and closable.

In the conventional systems described above, three handles must be operated individually to discharge hot water from the solar water heater, hot water from the boiler, and water, so it is easy to get confused in selecting the handle, and the ease of operation is reduced. It lacks. In addition, if you operate only one of the handles on the hot water side or the water side to adjust the temperature while the mixed water is being discharged, the discharge amount will change. If only one of the handles is operated, the temperature of the mixed water changes, so it is cumbersome to have to operate both handles, and the operation is not quick. Also, since the hot water side and water side handles cannot be operated at the same time with one hand, one must always operate one handle first, which takes time to obtain mixed water at the appropriate temperature, and there is a lot of waste of hot water being discharged. As it becomes,
If a person who is not familiar with this type of operation valve carelessly operates the handle on the hot water side first, hot water may be discharged and cause unexpected injury. This operation valve has the trouble of having to operate both the hot water side and water side handles in order to shut off the water when the mixed water is being discharged. In order to solve this problem, if a separate water stop valve is installed in the mixing channel to shut off the water, the hot water outlet and the water outlet remain open, so the mixed water flows back from the hot water outlet and the water outlet. There is a risk.

The present invention solves the above problems, improves the ease of operation, prevents the discharge amount from changing even if the mixed water temperature is adjusted, and prevents the mixed water temperature from changing even if the mixed water discharge amount is adjusted. The purpose is to improve the speed of operation and eliminate unnecessary discharge of hot water.

The basic configuration of the present invention consists of a first hot water supply chamber into which hot water flows into the solar water heater, and a second hot water supply chamber into which hot water from the boiler flows.
A main body having a hot water supply chamber, a water supply chamber into which water flows, a valve chamber in which a valve device is housed, and a discharge chamber from which mixed water is discharged, a valve device housed in the valve chamber, and a valve device that operates the valve device. It is equipped with an operation handle that allows you to
The valve device has a hot water inlet communicating with the first hot water supply chamber in the main body, a hot water inlet communicating with the second hot water supply chamber, a water inlet communicating with the water supply chamber, and a mixed water inlet communicating with the discharge chamber. a fixed plate having a discharge port; a movable movable plate having a concave mixing channel that communicates the hot water inlet and the water inlet of the fixed plate with the mixed water discharge port; The fixed plate is unrotatably installed in the valve chamber, and the movable plate is slid by the operating handle while remaining in close contact with the fixed plate, thereby connecting the hot water inlet, the water inlet, and the mixed water outlet. Through the communication, hot water, water, or mixed water can be selectively discharged.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

The hot water inlets 19, 20 and the water inlet 21 have a circular shape on the side facing the bottom 9 of the valve chamber 2, and a recessed circular groove shape on the side facing the movable plate 17 having a predetermined arc length. . There are through holes 10, 11, 1 between the fixed plate 16 and the bottom 9.
The sealing material 22 is attached so as to surround the fixing plate 1.
6 and the bottom 9 are kept watertight.

Movable plate 17 that is brought into close contact with the fixed plate 16
is made of ceramics formed into a disk shape with a smaller diameter than the fixed plate 16, and connects one or two of the hot water inlets 19, 20 and the water inlet 21 to the mixed water outlet 18 on the side facing the fixed plate 16. A mixing channel 23 for communication is recessed. An engagement hole 24 having a rectangular planar shape is formed in the center of the front surface of the movable plate 17 at a position eccentric from the axis, and a portion of the engagement hole 24 is also cut out by a predetermined arc length in the outer periphery of the front surface. A fan-shaped cutout 25 is formed. The engagement protrusion 15 of the cartridge case 14 can be fitted into and removed from the notch 25, and when the engagement protrusion 15 is fitted into the notch 25, the engagement protrusion 15 is inserted into the protrusion 26 on both sides of the notch 25. The amount of rotation of the movable plate 17 is regulated to a predetermined angle by the engagement protrusion 15 coming into contact with the movable plate 17 .
In order to avoid interference with the engagement protrusion 15, a recess 27 is formed on the opposite side of the notch 25, and the movable plate 17 is not inserted into the engagement protrusion 15. Allows for 360° rotation.

28 is a lever guide and the cartridge case 14
The tip of an operating lever 31 is rotatably fitted into the front end of the lever, has a rectangular guide hole 29 in the center, is inserted into the guide hole 29, and is pivotally connected to the lever guide 28 with a pin 30. is fitted into and engaged with the engagement hole 24 of the movable plate 17. Lever guide 2
A cover 33 is provided on the outside of the valve chamber 8, and the cover 33 is screwed onto the valve chamber 2 so as to be unrotatable. A display 34 is attached to the front surface of the cover 33 to indicate the discharge position and discharge direction of hot water from the solar water heater, hot water from the boiler, water, and mixed water thereof. An operating handle 32 is attached to the end of the operating lever 31 protruding from the cover 33, and by operating the operating handle 32, the movable plate 17 can be slid.

35 is a discharge pipe that communicates with the discharge chamber 3 and discharges the mixed water; 36 is a lift pipe of the solar water heater; 37 is a downfall pipe of the solar water heater; and 38 is connected to a hot water supply pipe of the boiler to supply hot water to the main body 1. A leg pipe 39 is connected to a water pipe and water flows into the main body 1, and 40 is a water pumping port that communicates the water supply chamber 6 and the water pumping chamber 7, and is opened and closed by a water pump 41. 41 is the handle 42
operated by. Reference numeral 43 is a drain plug that closes the drain hole 8, and is opened in winter to prevent the solar water heater from freezing.

In the above operating valve, the hot water from the solar water heater is
Hot water from the boiler flows into the hot water supply chamber 4, hot water from the boiler flows into the second hot water supply chamber 5, and water flows into the water supply chamber 6.

To pump water to the solar water heater, the handle 42 of the water pump 41 is operated to open the water pump port 40.
After the water pumping is finished, the water pumping port 40 is closed.

The positions of the operating handle 32 and the movable plate 17 shown in FIGS. 1 and 2 are in a stopped state in which neither hot water, water nor mixed water is discharged, and in a movable state as shown in FIGS. 2 to 4. Since the mixing channel 23 of the plate 17 corresponds only to the mixed water outlet 18 and neither hot water nor water flows into the mixing channel 23, no hot water is discharged.

When the operating handle 32 is tilted as it is (in the direction of arrow R in FIG. 1), the movable plate 17 that engages with the operating lever 31 slides linearly downward while remaining in close contact with the fixed plate 16, as shown in FIG. 6. The engaging protrusion 15 of the cartridge case 14 fits into the notch 25 of the movable plate 17 in this manner. At this time, since the mixing channel 23 of the movable plate 17 overlaps the hot water inlet 20 and the water inlet 21 at the same time as shown in FIG. The boiler hot water and water are mixed in the mixing channel 23 and discharged from the mixed water discharge port 18 into the discharge chamber 3, and further discharged from the discharge pipe 35 as mixed water. The discharge amount is adjusted by adjusting the sliding amount of the movable plate 17 in the linear direction.
This is done by making the area of 3 smaller or larger. When the operating handle 32 is rotated clockwise (direction of arrow Q) from the position shown in FIG. 1, the movable plate 17 also rotates in the same direction, so that the mixing flow path 23 corresponds more to the hot water inlet 20, and the water flow Since the inlet 21 is small, the amount of hot water flowing in is large, and the amount of water flowing in is small, so that the temperature of the mixed water increases. To lower the temperature of the mixed water, rotate the operating handle 32 counterclockwise (in the direction of arrow Q'). Operation handle 3
2 to the maximum clockwise direction, the engagement protrusion 15 and the protrusion 26 come into contact and the rotation of the movable plate 17 is restricted, and at that position, the mixing flow path 23
corresponds to the hot water inlet 20 and the mixed water outlet 18,
Since it no longer corresponds to the water inlet 21, no water is discharged, and only hot water from the boiler is discharged. When the operating handle 32 is rotated counterclockwise to the maximum extent, only water is discharged.

To discharge the mixed water of hot water and cold water from the solar water heater, rotate the operating handle 32 approximately 120 degrees counterclockwise from the discharge stop position shown in FIG. When the operation handle 32 is tilted in the direction of arrow R after being set to the use position, the movable plate 17 slides linearly, and the mixing flow path 23
corresponds to the hot water inlet 19 and the water inlet 21 at the same time, so the hot water and water flowing into the mixing channel 23 from both the inlets 19 and 20 are mixed in the mixing channel 23 and the mixed water is released from the discharge pipe 35. It is expelled. The temperature and discharge amount of the mixed water may be adjusted in the same manner as described for the discharge of hot water from the boiler.

To mix and use hot water from the solar water heater and hot water from the boiler, rotate the operating handle 32 120 degrees clockwise from the discharge stop position shown in Figure 1 to use the solar water heater and boiler. When the operating handle 32 is tilted after setting to the position, the movable plate 1
7 slides linearly, and the mixing flow path 23 is connected to the hot water inlet 1.
9 and the hot water inlet 20 at the same time, the hot water flowing into the mixing channel 23 from both the inlets 19 and 20 is mixed in the mixing channel 23 and flows into the discharge pipe 3.
Discharge from 5. In order to use hot water from the solar water heater and hot water from the boiler independently, the operating handles 32 may be rotated as much as possible in the direction of the respective use positions.

At the discharge stop position, the engagement protrusion 15 of the cartridge case 14 has escaped from the notch 25, and the axis M of the movable plate 17 and the center of rotation N are eccentric, so that the movable plate 17 The engaging protrusion 15 in the recess 27 is configured to escape from the recess 27 as the movable plate 17 rotates, as shown in FIG. 8, so that the engaging protrusion 15 and the protruding part 27 do not interfere with each other. There is. Therefore, at the discharge stop position,
The operating handle 32 moves clockwise and counterclockwise.
Can be rotated 360°.

Since the present invention has the above configuration, it has the following advantages.

(1) Discharge and stop of hot water from the solar water heater, hot water from the boiler, water and mixed water, as well as adjustment of the temperature and discharge amount of the mixed water, can be performed simply by operating one operating handle with one hand. , it is easy to use and you won't have to worry about choosing the handle.

(2) Regardless of the discharge position, the operation handle can quickly switch between dispensing and stopping hot water by simply tilting it, eliminating wasted use of hot water.

(3) There is no change in the discharge amount even if the operation handle is operated to adjust the temperature, or the temperature does not change even if the operation handle is operated to adjust the discharge amount, so the mixed water can be discharged stably. Can be done.

(4) When the discharge of mixed water is stopped temporarily, each inlet is completely blocked by the movable plate, so the mixed water does not flow back to the inlet.

(5) By switching the lift valve and drain valve, water can be pumped to and drained from the solar water heater quickly and reliably.
