The pipe body 10 has an inlet 11 through which hot water is introduced and an outlet 12 through which hot water is discharged, respectively, formed at both ends, and the first coupling hole 13 and the second coupling hole 14 are fixed on the outer circumferential surface thereof. Is formed at intervals, the first partition plate 15 protrudes on the inner wall facing the first coupling hole 13 and the pair of second partition plate 16 on the inner wall facing the second coupling hole 14 ) Is protruding.

The opening and closing valve 60 is coupled to the first coupling hole 13 to open and close the passage 17 between the upper end of the first partition plate 15 and the first coupling hole 13.

The on-off valve 60 is coupled to the first coupling hole 13 and seated on the upper end of the first compartment plate 15, the inlet hole 61a through which the heating water flows in and the discharge hole through which the heated heating water is discharged ( 61b) is formed and is coupled to the diaphragm 61 elastically deformed by the hydraulic pressure of the heating water, and the chamber 62 between the diaphragm 61 and the upper portion of the diaphragm 61. A valve body 65 to be formed, one end is coupled to the valve body 65, the other end is loosely coupled to the inlet hole 61a and the pin member 63, the upper and lower parts in the central portion of the valve body 65 And a plunger 64 which is provided to be movable to the center and pressurizes the central portion of the diaphragm 61, one end of which is coupled to the valve body 65 and the other end of which the plunger 64 is connected to the plunger 64. Electrical control to move the first spring 66 and the plunger 64 to press the diaphragm 61 up and down The force applied to the plunger 64 to maintain the separation state when the plunger 64 is separated from the diaphragm 61 by the coil 67 to which a signal is applied and the electric control signal of the coil 67. It is provided with a permanent magnet 68 for applying.

1 is a state in which the on-off valve 60 is closed, and the power is released to the coil 67 so that the plunger 64 is lowered by the restoring force of the first spring 66 to pressurize the diaphragm 61. 17) is closed.

As shown in FIG. 2, when the electric control signal is applied to the coil 67, the plunger 64 is raised while compressing the first spring 66, and at this time, due to the attraction force with the permanent magnet 68. The raised state of the plunger 64 is maintained. That is, while compressing the second spring 69 by the attraction force of the permanent magnet 68, the permanent magnet 68 is lowered to come close to the plunger 64, thereby raising the raised state (opening of the valve) of the plunger 64. Will be maintained.

As shown in FIG. 2, when the plunger 64 is raised, the diaphragm 61 is pushed upward by the hydraulic pressure of the heating water so that the passage 17 is opened. At this time, the fin member 63 enters the inlet hole 61a of the diaphragm 61 to remove rust or foreign matter, thereby smoothly flowing the heating water.

On the other hand, the flow control valve 70 is coupled to the second coupling hole 14 to control the flow rate of the heating water via the upper end of the second compartment plate 16.

The flow control valve 70 is the valve case 75 coupled to the second coupling hole 14 and the valve case 75 so as to move in a direction away from the direction close to the second coupling hole 14. A passage 18 between the shaft member 71 coupled to the second compartment plate and one end of the shaft member 71, one side of which is spaced or in contact with the second compartment plate 16. It includes; flow control unit consisting of an opening and closing member 72 capable of opening and closing, wherein one surface of the opening and closing member 72 is the amount of fluid flowing through the passage 18 in accordance with the distance to the passage 18 It has a shape that can be changed.

3 and 4, the flow rate control part includes a shaft member 71 and an opening / closing member 72. The shaft member 71 is coupled to the valve case 75 and moves upward and downward. Specifically, the shaft member 71 is disposed above the passage 18 and moves away from the channel 18. It is configured to move the slide.

Meanwhile, an airtight member (not shown) for airtightness is provided between the shaft member 71 and the valve case 75 to prevent the fluid in the chamber from leaking to the outside during the movement of the shaft member 71. Can be.

The opening and closing member 72 is coupled to one end of the shaft member 71 and is configured such that one surface thereof may be in contact with the second partition plate 16 of the passage 18. Specifically, the passage 18 can be closed in contact with the second partition plate 16.

In addition, the opening and closing member 72 may be spaced apart from the second partition plate 16 around the passage 18 as the shaft is raised, and thus the opening degree may be gradually increased. On the other hand, one surface of the opening and closing member 72 in contact with the second partition plate 16 may have a U-shaped or V-shaped cross-sectional shape rather than a flat plane shape and may have a hemispherical shape as a whole. As described above, as the U-shaped cross-sectional shape of the opening and closing member 72 rises and is spaced apart from the second partition plate 16, the amount of fluid flowing through the passage 18 may be changed.

That is, when the opening and closing member 72 is raised to make a slight distance between the opening and closing member 72 and the second compartment plate 16 and the opening degree is only slightly opened, the outlet 12 through the passage 18 is opened. The amount of fluid flowing to the side becomes small.

In the drawing, a V-shaped port as in FIG. 5A is employed, and a U-shaped port may be used as in the dotted circle A of FIG. 1 and FIG. 5B.

On the other hand, when the separation distance of the opening and closing member 72 is further increased, the amount of fluid may be gradually increased. As such, the amount of fluid can be achieved by the opening and closing member 72 having a U-shaped cross section rather than a flat shape. Also, the increase in the amount of fluid does not increase linearly but increases nonlinearly. In other words, in the initial space, the amount of fluid is gradually increased, but if the separation distance is greater than a certain amount, the amount of flowing fluid may be increased more or less quickly.

Such a flow control valve can be expected to save energy by changing the flow rate value of the main constant flow valve by checking the heating location of the in-generation distributor in the heating field.

The valve unit of the present invention as described above has a structure in which the on-off valve 60 for blocking and supplying the heating water to each room and the flow control valve 70 for controlling the flow rate are coupled to one pipe body 10. As a result, its structure is simple and its construction is simple.

In addition, since the rust or foreign matter deposited in the inlet hole 61a of the diaphragm 61 is removed by the pin member 63 when the diaphragm 61 of the on-off valve 60 is operated, the heating water can flow smoothly. .
