Semi-automatic fire fighting sprinkling device for electromagnetic valve

Abstract

The invention relates to a semi-automatic fire fighting sprinkling device for an electromagnetic valve. The device comprises a glass ball water sprinkler arranged at the output end of a water injection nozzle; and the water injection nozzle is connected to a water inlet pipeline. The device is characterized by further comprising a smog sensor and the electromagnetic valve for controlling the waterinlet pipeline to turn on and off water supply of the glass ball water sprinkler. The electromagnetic valve is arranged in the water inlet pipeline and is connected to the smog sensor. Compared withthe prior art, the smog sensor and the electromagnetic valve are additionally arranged while the glass ball water sprinkler is retained, so that the device can spray water to extinguish fire still during outage, and moreover, the electromagnetic valve can cut off water supply after fire is extinguished, so that the loss is reduced.

Description

technical field [0001] The invention relates to a fire-fighting sprinkler device, in particular to a semi-automatic solenoid valve fire-fighting sprinkler device. Background technique [0002] In the fire fighting work, the most important part of the fire sprinkler is the glass ball sprinkler. Its job is to monitor whether a fire occurs. When a fire breaks out, when the temperature reaches a certain level, the glass sphere is broken, and the water flow in the pipeline is sprayed upwards, downwards or sideways to the splash plate of different designs, so as to achieve the purpose of automatic sprinkler fire extinguishing. At present, it is divided into pendant type sprinkler head, vertical type sprinkler head, ordinary type sprinkler head, side wall type sprinkler head and so on. In the event of a fire, the fire water is evenly sprinkled through the sprinkler head to control the fire in a certain area. The common types of sprinkler heads are: drooping type, vertical type, or...

AI Technical Summary

Problems solved by technology

[0003] However, the current fire sprinkler devices currently have the problem of poor controllability. Only when the temperature reaches a certain level will the glass balls break, and it cannot cooperate with other detection methods to prevent fires in advance.

In addition, when the glass ball of the fire sprinkler device is broken, the fire water will only stop after the fire valve is closed or the reserve water of the fire water tank is exhausted, resulting in waste of water and unnecessary property loss.
