The compositeness valve to control the temperature and flux

The present invention relates to a composite valve for controlling the temperature and flow rate, and can be manufactured by reducing the production cost by easily adjusting the flow rate and the opening and closing function according to the temperature in one valve, it is possible to easily balance the valve to the heating area The flow rate can be adjusted accordingly. Of course, the heating temperature can be kept constant, and the combined valve is installed on the return header side to reduce the saturated steam pressure caused by the hot water passing through the combined valve. Of course, the bubble generation rate can be reduced accordingly, and the generated bubbles can be discharged directly to the outside through the return header and the return pipe without going through the water supply line buried in the floor, so that the temperature and flow rate can be prevented. It relates to a combined valve to control.

In general, the hot water distributor for heating is provided with a temperature control valve for controlling the temperature and a flow control valve for adjusting the flow rate. As described above, in a typical heating hot water dispenser installed with a flow control valve and a temperature control valve, the fluid is a flow control valve. Explosion sounds occur when bubbles are generated when they pass through them.

In addition, the noise generated by the explosion sound is largely generated at a portion where the pipe of the flow control valve is bent or at a high flow rate, that is, at the inlet side at which the flow control cone is configured. This bubble is caused by the saturated steam pressure increased as the temperature of the fluid passing through the flow control valve is high.

In addition, when not using for a long time, or if you do not want to flow the flow into the return header (4) due to the inspection, etc., as shown in Figure 3, the opening 12 configured in the valve body 10 is flow rate adjustment The limit pin 40 coupled to the piston actuating portion 20 is rotated upward by rotating the limit plug 50 coupled to the valve body 10 in the above-described manner so as to be closed by the cone 30. It is possible to prevent the movement, and thereby the flow control cone 30 can completely close the opening 12 to prevent the flow rate flow into the return header (4).

And, if you want to manually operate the flow of the flow flowing into the return header (4), as shown in Figure 8 by pressing the handle plug 130 configured at the top block key of the key block 110 ( By removing the 111 from the operation key groove 122 of the piston operation cam 120 may be manually operated irrespective of the motor gear 101 configured in the power supply unit 100.

Hereinafter, the operation according to the flow of hot water will be described in more detail.

As described above, the hot water introduced into the water supply header 2 through the water supply pipe 1 in the boiler is introduced into a high temperature hot water at about 75 ° C. The high temperature hot water passes through a plurality of water supply lines 3 passing through the floor. It cools down while passing through the return header (4) when it is changed to hot water of about 40 ℃ low temperature.

As such, in the present invention, since the combined valve 150 for controlling the temperature and the flow rate is coupled to the return header 4, the hot water passing through the flow regulating cone 30 and the opening 12 is a low temperature hot water. When the saturated steam pressure is lowered, fewer bubbles are generated when passing through the flow control cone 30 and the opening 12.

In addition, since the generation of bubbles generated while passing through the opening 12 formed in the valve body 10 occurs in the return header 4, even if the bubbles are immediately destroyed and noise is generated, soundproofing is performed in the return header 4 itself. In addition, since the noise is discharged directly through the return pipe (5), the noise is not spread to the room where the user resides.

In addition, since one of the valves coupled to the return header 4 has a flow regulating function and an opening / closing function, the flow rate can be appropriately adjusted according to the heating area, thereby maintaining a constant heating temperature.

Although the above-described embodiment has been described with respect to the most preferred example of the present invention, it is not limited to the above embodiment, and it is common in the technical field to which the present invention belongs that various modifications are possible without departing from the technical idea of the present invention.
