Embodiment Construction

[0011] As shown in the figure, a control circuit includes a controller, a power module, a detection device, a relay, a solenoid valve, an audible and visual alarm, and a motor. The AC voltage is converted into a 24V DC power supply through the power conversion circuit DC, which is The controller and the detector provide the working voltage, and the solenoid valve and the motor are controlled to start and close through the relay.

[0012] The detection device includes a water level detector SKQ, a flame detector HY and a smoke detector GY in the water tank. The water level is detected by the water level detector SKQ, and the detection information is sent to the main controller, and the water tank inlet pipe is controlled by the controller. The valve for water tank replenishment.

[0013] The relay controls the solenoid valve DCF, the stop valves JZF1~JZF5, the throttle valve JLF and the overflow valve YLF, and controls the fire protection circuit by controlling the switches of ...

Abstract

The invention discloses a control circuit which comprises a controller, a power module, a detection device, a relay, an electromagnetic valve, an audible and visible alarm device and a motor, wherein a power conversion circuit DC converts alternating current voltage into 24V direct current power so as to supply working voltage to the controller and a detector; the controller receives a detection signal of the detection device; starting and stopping of the electromagnetic valve and the motor are controlled by the relay through analytic judgment, so that fire extinguishing operation is finished. The control circuit is advanced in fire extinguishing mechanism, high in fire extinguishing efficiency, safe, harmless and pollution-free to the environment and has high use efficiency and good economical benefit.

Description

technical field [0001] The invention belongs to a fire alarm system, and in particular relates to a control circuit. Background technique [0002] With the development of modernization in our country, the construction of various types of industrial buildings is developing rapidly. During the construction process, people pay more and more attention to the prevention of fire, especially. In recent years, the national fire protection law has promulgated and implemented relevant laws and regulations, and the prevention of fire in engineering construction has been raised to the height of law. The principle of "prevention first, combination of prevention and fire prevention" that is required for the fire protection system indicates that the automatic fire alarm system will play a more important role. Fire, poisonous gas leakage, and flammable gas explosion are safety issues faced by all production units at present. These all directly threaten the health of employees and the safet...
