AI Technical Summary
The control response speed of existing fire-proof and smoke exhaust systems is slow and easy to generate control errors, resulting in the inability to effectively prevent the spread of fire smoke.
A fire-proof and smoke exhaust system is designed, which includes a duct network, a fire-proof and smoke exhaust valve, an actuator and a control panel. The actuator is directly connected to the control shaft of the fire-proof smoke exhaust valve through the rotating shaft and the rotating motor. The rotating position detection mechanism and the limiting mechanism are used to accurately control the position of the turntable, so as to quickly respond and accurately control the opening and closing of the fire-proof smoke exhaust valve.
By directly setting the actuator on the fire-proof smoke exhaust valve and directly connecting it with the control shaft of the blade, the response speed and control accuracy of the fire-proof smoke exhaust valve are improved, and the problem of control error in the existing system is solved.
