Problems solved by technology

However, once the glass bulb shell of this sprinkler is broken, the sprinkler will be scrapped and cannot be reused. Unless the water source is cut off, it will be difficult to close it. After the fire is extinguished, the broken glass bulb will still be sprinkled with water, and a large amount of precious water resources will be wasted.

Embodiment 1

[0027] Such as figure 1 As shown, this embodiment provides a manually and automatically controllable fire sprinkler device 1 , including a sprinkler valve 2 and a sprinkler head 3 . The spray valve 2 includes a water inlet at the upper end and a water outlet at the lower end, a spray valve opening and closing device on the water inlet channel between the water inlet and the water outlet, and the spray valve opening and closing device includes A valve core 4 for opening and closing the spray valve 2 and a temperature-sensitive glass tube 5 for controlling the valve core 4 to open and close the spray valve 2; the spray head 3 is arranged in communication with the water outlet.

[0028] The inside of the temperature sensing glass tube is filled with a thermosensitive solution, such as alcohol or mercury.

[0029] The working principle of the fire-fighting sprinkler device 1 is: when there is no fire on site at ordinary times, that is, when the ambient temperature is normal, the ...

Embodiment 2

[0038] Such as figure 2As shown, this embodiment provides another implementation on the basis of Embodiment 1. In this embodiment, a heating device for heating the temperature-sensitive glass tube 5 is also provided, and the heating device is a heating sheet 9 or the heating wire, when a fire occurs and the ambient temperature does not reach the rupture temperature of the temperature-sensing glass tube 5, the heating device can be manually activated to heat the temperature-sensing glass tube 5, so that the temperature-sensing glass tube 5 expands and ruptures when heated After that, open shower nozzle 3 to spray water.

[0039] As an optional implementation manner, in this embodiment, the heating device is a heating sheet 9 , and the heating sheet 9 is heated by a power source 10 .

[0040] Such as image 3 Shown is the installation diagram of the fire sprinkler device 1 described in Embodiments 1-3 of the present invention, and a plurality of the fire sprinkler devices 1 a...

Abstract

The invention relates to a fire-fighting spraying device capable of being manually and automatically controlled. The fire-fighting spraying device comprises a spray valve and a spray head, wherein a water inlet passage between a water inlet and a water outlet of the spray valve is provided with a spray valve opening-closing device; furthermore, the spray valve opening-closing device comprises a valve core used for opening and closing the spray valve and a temperature sensing glass pipe used for controlling the valve core to open and close the spray valve; and the spray head is communicated with the water outlet. When a fire disaster occurs, environmental temperature rises, a thermosensitive solution in the temperature sensing glass pipe expands when being heated to directly result in fracture of the temperature sensing glass pipe, the valve core is released to open the water inlet passage of the spray valve, meanwhile the spray head is automatically opened to spray water for putting out a fire, so that automatic opening of the fire-fighting spraying device is realized; and after fire fighting is finished, water spraying is stopped in time, and repeated use can be realized, so that the cost is effectively saved, and huge waste of water resources can be avoided.

Description

technical field [0001] The invention belongs to the technical field of fire control equipment, and in particular relates to a manually and automatically controllable fire sprinkler. Background technique [0002] Fire prevention work and fire fighting work are the two major focuses of fire protection. To protect personal, property and public safety, it is necessary to do a good job in fire prevention work and at the same time establish practical fire extinguishing facilities. [0003] After a fire occurs, in order to minimize the loss, the most effective fire extinguishing method must be adopted. Common fire extinguishing methods include: manual fire extinguishing and automatic fire extinguishing. Manual fire extinguishing is carried out by using fire trucks, ladder trucks, fire hydrants, fire bombs, fire extinguishers and other equipment. Although this method has the advantages of intuitiveness, flexibility, and low engineering cost, the height that fire trucks and ladder...
