Standby State: When there is no fire, the sealed pipe plug at the inlet of the short pipe remains securely closed due to the operation of the transmission mechanism. This effectively prevents the pressurized water within the pipe from flowing into the short pipe located beneath the nozzle.
Fire trigger: In the event of a fire, the rising temperatures cause the glass bulb temperature-sensing element within the nozzle to shatter.
Mechanical Transmission: Once the glass bulb shatters, the transmission mechanism that it once supported—comprising components such as transmission tubes and compression springs—is set free. The force exerted by the spring then propels the transmission mechanism, ultimately leading to the opening of the sealed pipe plug.
Sprinkler fire extinguishing: After the pipe plug is opened, pressurized water can enter the short pipe and eventually be evenly sprayed out through the splash pan of the nozzle to achieve fire extinguishing.
