Multifunctional automatic water spray fire-extinguishing device

Abstract

The invention provides a multifunctional automatic water spray fire-extinguishing device which comprises a valve body separated into an upper cavity and a lower cavity by a separator and a valve plate, as well as an open sprinkler communicated with a water outlet of the valve body, wherein a water inlet cavity is formed in the upper part of the valve body, and a water outlet cavity is formed in the lower part of the valve body; the valve plate is connected to an opening in the separator; a first valve rod is connected to the center of the valve plate; a magnet is arranged on the lower side wall of the water outlet cavity; a vertically downward fixed rod is connected to the valve body; a guide bracket which is horizontally arranged is fixedly connected to the fixed rod; the first valve rod passes through a hole in the lower side wall of the water outlet cavity and a hole in a guide bracket, and the lower end of the first valve rod is vertically connected with a first glass ball in a pressing manner; the first glass ball is supported by a supporting plate, and the supporting plate is fixedly connected with the guide bracket through a lifting rod. According to the device disclosed by the invention, the problem that a spray header needs to be vertically arranged when the projection area of a transparent suspended ceiling is 15-70 percent is solved, the problem that water stored in a conventional dry pendent sprinkler adapter tube is frozen is also solved, and moreover, the problem that an upright sprinkler is difficult to arrange due to the influence of a blocking object is solved.

Description

technical field [0001] The invention relates to a fire extinguishing device, in particular to a multi-functional automatic sprinkler fire extinguishing device which is suitable for a permeable ceiling such as a grid or grid plate, which requires antifreeze and has many obstacles under the roof. Background technique [0002] With the development of society, all kinds of new ceiling materials and design methods appear, and there are many permeable ceilings in the form of building ceilings. For sites with permeable ceilings such as grids and grids, when the projected area of ​​the ceiling is 15% to 70%, nozzles should be installed on both the upper and lower sides of the ceiling. The lower aggregate is not enough to spray water without breaking. At this time, even if the upper nozzle breaks and sprays water, the fire extinguishing effect will be weakened due to the shelter of the ceiling. [0003] When the indoor temperature in the north is lower than 4°C and the projection ar...

Problems solved by technology

[0002] With the development of society, all kinds of new ceiling materials and design methods appear, and there are many permeable ceilings in the form of building ceilings. For sites with permeable ceilings such as grids and grids, when the projected area of ​​the ceiling is 15% to 70%, nozzles should be installed on both the upper and lower sides of the ceiling. The lower gathering is not enough to spray water without breaking. At this time, even if the upper nozzle breaks and sprays water, the fire extinguishing effect will be weakened due to the shelter of the ceiling.

[0003] When the indoor temperature in the north is lower than 4°C and the projection area of ​​the ceiling is 70%~100%, the automatic sprinkler system usually adopts the pre-action system, and according to the measures, the sprinkler should be arranged under the ceiling, and the sprinkler should be a dry pendant sprinkler. In order to prevent the pipes or nozzles from freezing and cracking, but after the pipe network is tested for water, the water in the standpipe connected to the nozzles cannot be discharged, and there will be water. When the temperature is low, the water will freeze. If a fire occurs at this time, it will take a certain amount of time for the ice to melt Time will inevitably delay the function of the automatic sprinkler system

[0004] For the indoor space where the projected area of ​​the ceiling is 0%~15%, according to the requirements of the specification, the sprinklers should be arranged under the roof, and the vertical sprinklers should be used. However, it is often encountered in the project that the roof beams are very dense and there are many various pipelines in the ceiling. In some cases, the water spray effect will be blocked or a large number of encrypted sprinklers will need to be added, resulting in a large amount of water in the system and a very complicated system layout
