The cover part 220 and the air inlet 230 have connection parts 222 and 232 connected to the solenoid valve 240.

The sealing member 210 is formed in a pipe shape by winding a metal plate in a cylindrical shape, and a cylindrical air inlet 230 through which the inside is penetrated so that air of the turbo blower 100 is introduced therein.

The diaphragm 212 is mounted on the inner upper portion of the sealing member 210, and a cylindrical valve seat 213 is mounted on the lower part of the diaphragm 212.

The valve seat 213 is formed on the upper inner surface of the air inlet 230, and a plurality of openings 217 through which the high pressure pressurized air introduced from the air inlet 230 is discharged are formed in the upper side surface of the cylindrical shape.

The valve seat 213 has a cylindrical connecting portion 214 connected to the lower surface of the diaphragm 212 at the upper end, and the diaphragm spring 215 is mounted therein, and the diaphragm at the lower end. A spring 215 is mounted to form a cylindrical pedestal 216 through which the central portion is penetrated.

The connecting portion 214 of the valve seat 213 on which the diaphragm 212 is mounted is located at the upper end of the air inlet 230, and the outside of the air inlet 230 is slid by the elastic force of the diaphragm spring 215. Can protrude.

The lower end of the air inlet 230 penetrates through the lower end of the sealing member 210 to the outside and is connected to the outlet of the turbo blower 100.

The sealing member 210 forms a cylindrical first soundproof member 218a along the inner surface edge.

The air inlet 230 formed in the sealing member 210 forms a second sound insulating member 218b having a cylindrical shape surrounding the outer surface edge.

An air outlet for discharging the air flowing into the air inlet 230 is formed at a predetermined interval between the first soundproof member 218a and the second soundproof member 218b.

In the solenoid valve 240, the first port 242 is connected to the connection part 222 of the cover part 220 through the first tube 242a to be connected to the air pressure counterspace part S1 of the diaphragm 212. The second port 244 is connected to the connection portion 232 of the air inlet 230 through the second tube 244a and is connected to the air pressure inlet space S2.

In other words, the second port 244 of the solenoid valve 240 is connected to the connection portion 232 formed at the lower end of the air inlet 230. The third port 246 of the solenoid valve 240 discharges high speed pressurized air to the outside.

The solenoid valve 240 is a three-way valve having a first port 242, a second port 244, and a third port 246, and any valve can be used as long as it is a three-way valve.

As shown in Figure 3, showing the operation of the turbo blower rapid exhaust device 200 according to an embodiment of the present invention as follows.

Referring to FIG. 3, in order to maintain the closed state of the rapid exhaust device 200, the solenoid valve 240 is closed by closing the third port 246 by shutting off the power supply of the solenoid valve 240 during the normal operation of the turbo blower 100. ) Is connected to the air pressure counter space (S1) through the connection part 222 of the cover part 220 at the connection part 232 of the air inlet 230. Here, the air passage refers to an air passage formed from the connecting portion 232 of the air inlet 230 to the connecting portion 222 of the cover part 220 through the second port 244 and the first port 242.

The air flow path formed as described above continuously supplies the pressurized air of the air inlet port 230 of the rapid exhaust device 200 to the air pressure counter space portion S1 of the diaphragm 212 to provide a turbo blower of the air inlet port 230. Generates a force against the discharged air of 100).

At this time, the air pressure counter space portion S1 of the diaphragm 212 and the air pressure of the air pressure inlet space portion S2 of the air inlet 230 are the same, but the air pressure counter space portion of the diaphragm 212 ( Since the area of S1) is large, the valve seat 213 moves to the lower end side of the air inlet 230, and the diaphragm 212 comes into close contact with the upper end of the air inlet 230 to prevent air leakage.

The closed state of the turbo blower rapid exhaust device 200 is discharged through the check valve 300 so that the discharge air of the turbo blower 100 is prevented from surging due to the back flow.

As shown in Figure 4, showing the operation of the turbo blower rapid exhaust device 200 according to an embodiment of the present invention as follows.

Referring to FIG. 4, in the open state of the turbo blower rapid exhaust device 200, the pressure at the check valve 300 side increases at the time of initial startup of the turbo blower 100 or due to disturbance, and the discharge air of the turbo blower 100 is increased. When the surging phenomenon occurs, the rapid exhaust device 200 serves to exhaust the gas to protect the turbo blower 100.

In the open state of the rapid exhaust device 200, the air of the solenoid valve 240 is closed by closing the second port 244 of the solenoid valve 240 by applying power to the solenoid valve 240 during the initial operation of the turbo blower 100. An air flow path is formed to discharge the pressurized air trapped in the air pressure counterspace portion S1 of the diaphragm 212 to the outside atmosphere in the direction of the flow path.

That is, the air passage refers to an air passage formed by the first port 242 and the third port 246 of the solenoid valve 240 at the connection portion 222 of the cover 220.

As a result, the pressure of the air pressure counterspace S1 of the diaphragm 212 is dropped, and the valve seat 213 is moved upward by the pressurized air of the air inlet 230. At this time, the elastic force of the diaphragm spring 215 acts together for the rapid movement of the valve seat 213.

When the valve seat 213 moves and touches the lid part 220, the rapid exhaust device 200 is completely opened, and the discharge air of the turbo blower 100 which has flowed back flows through the air outlet and the third of the diaphragm. To port 246.

The arrow direction of FIG. 4 shows the internal air flow in the open state of the rapid exhaust device 200.

At this time, the discharge air is a high-speed pressurized air to generate a high-pitched fluid friction sound, the noise is reduced by the soundproof member installed around the air inlet 230.

In this way, the rapid exhaust device 200 is integrally formed with the soundproofing member and uses the area difference of the diaphragm 212 without a separate guide shaft to close the air inlet 230 with the valve seat 213. The role and the sealing device of the air inlet 230 may be performed at the same time.

3 and 4, the rapid exhaust apparatus 300 according to the embodiment of the present invention is a sealing member 210 and the upper surface of the sealing member 210 formed in a pipe shape by winding a metal plate in a cylindrical shape Cover portion 220 covering the,

The sealing member 210 has a cylindrical air inlet 230 through which the discharge air of the turbo blower 100 flows, protrudes from the inside of the central portion of the sealing member 210 to the outside, and the air inlet 230 protrudes outside. Lower end of the) is connected to the outlet of the turbo blower (100).

The sealing member 210 moves the diaphragm 212 and the diaphragm 212 to the lower portion of the air inlet 230 at the lower portion of the diaphragm 212 and the diaphragm 212 in the upper portion of the air inlet 230. And a valve seat 213 mounted on the upper inner surface, and when the diaphragm 212 is moved to the lower surface of the cover part 220 until the predetermined pressure is reached using the solenoid valve 240 and reaches the predetermined pressure. The diaphragm 212 is to be in close contact with the upper end of the air inlet 230.
