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
The invention belongs to fire alarm system, be specifically related to a kind of control circuit.
Background technology
Along with the development of China's modernization construction, the construction of all kinds industrial building is accelerated development, and in process of construction, especially the strick precaution of fire is more and more valued by the people.NFA method has been promulgated and has been implemented relevant laws and regulations in recent years, in engineering construction, the strick precaution of fire is raised to the height of law.The principle of " put prevention first, combine prevention with fire fighting " that fire-fighting system requirements is implemented indicates that again automatic fire alarm system will play the part of more importantly role.Fire, toxic gas leak, flammable gas explosion this be the safety problem that current each production unit all faces, these all directly threaten the safety of the healthy and process units of worker, for big-and-middle-sized boats and ships, the safety that makes crewman is subject to serious threat by breaking out of fire, brings huge economic loss.If can, before fire occurs, can report to the police in advance, possible accident is eliminated early, by protection personnel's life security, the property loss while reducing fire generation.
Summary of the invention
Technical problem to be solved by this invention is the problem proposing for above-mentioned present situation, a kind of control circuit is provided, the fire extinguishing system of this system taking thin water smoke as extinguishing chemical has that extinguishing mechanism advanced person, fire-fighting efficiency are high, safety, without harm, environmentally safe, there is good service efficiency and economic benefit.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of control circuit, this control circuit comprises controller, power module, checkout gear, relay, magnetic valve, audible-visual annunciator and motor, by power-switching circuit DC, alternating voltage is converted to 24V dc source, for controller and detector provide operating voltage, the startup by Control magnetic valve and motor and closing.
Described checkout gear comprises level switch SKQ, flame detector HY and the smoke detector GY in water tank, by level switch, SKQ detects water level, and send detection information to master controller, carry out water tank moisturizing by the valve of controller control tank inlet pipe.
Described Control magnetic valve DCF, stop valve JZF1 ~ JZF5, choke valve JLF and overflow valve YLF, control fire-fighting loop by control relay KM1 ~ KM8 switch.
Control audible-visual annunciator FMQ by contactor K1 and report to the police, contactor K2 controls the start and stop of motor M.
Advantage of the present invention is: the fire extinguishing system of this system taking thin water smoke as extinguishing chemical has that extinguishing mechanism advanced person, fire-fighting efficiency are high, safety, without harm, environmentally safe, there is good service efficiency and economic benefit.
Brief description of the drawings
Accompanying drawing is circuit diagram of the present invention.
Detailed description of the invention
As shown in the figure, a kind of control circuit, this control circuit comprises controller, power module, checkout gear, relay, magnetic valve, audible-visual annunciator and motor, by power-switching circuit DC, alternating voltage is converted to 24V dc source, for controller and detector provide operating voltage, the startup by Control magnetic valve and motor and closing.
Described checkout gear comprises level switch SKQ, flame detector HY and the smoke detector GY in water tank, by level switch, SKQ detects water level, and send detection information to master controller, carry out water tank moisturizing by the valve of controller control tank inlet pipe.
Described Control magnetic valve DCF, stop valve JZF1 ~ JZF5, choke valve JLF and overflow valve YLF, control fire-fighting loop by control relay KM1 ~ KM8 switch.
Control audible-visual annunciator FMQ by contactor K1 and report to the police, contactor K2 controls the start and stop of motor M.
The concrete implementation of this control circuit is: power module DC provides operating voltage for controller, by flame detector HY and smoke detector GY, surveyed area is surveyed, in the time that flame detector HY and smoke detector GY detect fire signal simultaneously, the open and close controlling of controller control relay KM1 ~ KM8 switch to magnetic valve, by the level switch SKQ in water tank, water level signal is sent to controller, make controller control water charging system carry out water tank moisturizing, controlling audible-visual annunciator FMQ by contactor K1 reports to the police, the start and stop of K2 contactor control motor M.
