3 is a partial enlarged view of a three-way valve according to an embodiment of the present invention;
4 is an operational example of a three-way valve according to an embodiment of the present invention;

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings, but the present invention is not limited by the scope of the present invention.

Generally, a valve is used to control the flow rate or flow rate of the object or control the flow direction of the fluid during the transferring process. At this time, the above-mentioned valves are classified into types according to the control system and types according to the internal structure. Mechanical valves according to the control method are classified into mechanical valves and electronic valves according to the electric control method .

In addition to the above-mentioned classification, types classified according to the internal structure can be broadly divided into a single seated valve and a double seated valve. Also, the two-way valve is classified into a one-to-one correspondence (1: 1) and the three-way valve (two-to-one match).

At this time, the three-way valve is divided into a mixing valve having two inlets and one outflow, and a diverting valve having one inlets and two outlets.

The present invention relates to a three-way valve in the above case, and the conventional three-way valve has a problem in that the fluid is temporarily excessively introduced due to the internal pressure difference and the disc is damaged or broken.

1 to 3, the first embodiment of the three-way valve having the internal pressure control device according to the present invention includes two flow paths A and B into which the fluid flows, A valve body 100 forming one passage AB for discharging the fluid introduced from the valve body 100; A disk 200 mounted inside the valve body 100 for opening and closing a flow path through which the fluid moves up and down; An upper sheet 300A that abuts against the upper portion of the disc 200 when the disc 200 is lifted and closes one flow path B into which the fluid flows; A lower sheet 300B that abuts against a lower portion of the disc 200 when the disc 200 descends and closes another flow path A through which the fluid flows; A pressure sensor 500 mounted on each of the flow paths A, B and AB to measure pressure; The controller 200 controls the pressure in the valve 1 by opening the pressure adjusting hole 400 formed in the lower portion of the disc 200 when the pressure difference between the pressure sensor 500 and the pressure sensor 500 is greater than a set value, (700, not shown); . ≪ / RTI >

Specifically, the internal pressure of the valve 1 may be varied depending on the type and the remaining amount of fluid in the flow paths A, B, and AB. Therefore, it is preferable to check the pressure from time to time with the pressure sensor 500 as described above. When the flow path A, B or AB is opened when the pressure is equal to or more than a certain value, driving of the disk 200 is difficult to control, There is a risk of breakage due to rise or fall.

Accordingly, when the pressure exceeds a predetermined value, it is preferable that the pressure regulating hole 400 is opened to keep the pressure below a predetermined value.

The pressure regulating hole 400 is shaped like a camera diaphragm, so that the opening and closing area can be adjusted, and the pressure regulating hole 400 is wide.

In the second embodiment of the present invention, the controller 700 includes a communication module capable of communicating with a smartphone or a server. The controller 700 can check whether the valve 1 is open or closed and whether the valve 1 is normally operated, It is also possible to arbitrarily control opening and closing as necessary.

Further, in a device in which a plurality of valves 1 are provided, it is possible to perform Bluetooth communication between the valves 1, so that it is possible to previously open and close the following valve 1 by grasping whether the valves 1 are open or closed.

The third embodiment of the present invention is characterized in that a buffer agent 600 is mounted on the surface where the upper sheet 300A and the lower sheet 300B are in contact with the disk 200 so that the disk 200 is abruptly raised or lowered It is possible to reduce the noise and vibration during operation of the valve 1 and to improve the durability of the valve 1.

FIG. 4 shows an operation example of a three-way valve having an internal pressure control facility of the present invention.

Specifically, in the first drawing of FIG. 4, the disk 200 is maximally lifted, and the fluid flowing in the fluid A flows out through the fluid channel by opening the fluid A, as shown in FIG.

4, the disc 200 is partly lifted so that the fluid flowing in the A flow path and the fluid flowing in the B flow path escape through the AB flow path by partially opening the A flow path and the B flow path. .

4, the disk 200 is lowered as much as possible, and only the B channel is opened, so that only the fluid flowing in the B channel flows out through the AB channel.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
