<p>A blow-off valve for a turbo blower is provided to discharge blowing air from the turbo blower with fast and reliable operation by using air pressure of blowing air. A blow-off valve for a turbo blower includes a body(100), a spool valve(300), and a three-way valve(20). The body is connected with the turbo blower to receive blowing air from the turbo blower and has an air outlet to discharge the blowing air into the air. The spool valve is installed inside the body and includes a blowing pressure spool and a blowing pressure-against spool. The blowing pressure spool and the blowing pressure-against spool are placed in a blowing pressure inlet section(S1) and a blowing pressure against section(S2), respectively. The three-way valve is connected to the blowing pressure inlet section, the blowing pressure-against section and the air, and connects the blowing pressure-against section and the air by blocking the blowing pressure inlet section during initial driving of the turbo blower.</p> |
