Description

Improved indoor large-flow automatic fire extinguishing spray head

Technical Field

The utility model relates to a shower head, in particular to indoor large-traffic automatic fire extinguishing shower head of improved generation belongs to the fire control field.

Background

The water spraying fire extinguishing system is an indispensable important component in buildings such as office buildings, warehouses, factory buildings and the like, has the relation to the arrangement of articles inside the building and the personal safety, and can ensure property and personal safety by being provided with the automatic fire extinguishing spraying system.

Classified automatic water-spraying fire-extinguishing system of water-spraying fire-extinguishing system according to the switching form of shower nozzle, divide into 2 big types of closed automatic water-spraying fire-extinguishing system and open automatic water-spraying fire-extinguishing system, and closed fire-extinguishing system divide into according to theory of operation: wet sprinkler systems, dry sprinkler systems.

A wet type automatic water spraying fire extinguishing system of a closed type automatic water spraying fire extinguishing system.

The fire extinguishing system consists of a closed sprinkler head, a water flow indicator, a flow switch, a wet alarm valve group, a pipeline, a water supply facility and the like, wherein the pipeline is filled with water all the time and keeps certain pressure, and the closed automatic sprinkler system has the advantages of longest service time, most extensive application and highest fire control and extinguishing rate in the world. When in the warning state, pressure stabilizing facilities such as a fire water tank or a pressure stabilizing pump, air pressure water supply equipment and the like maintain the pressure of water filled in the pipeline. When a fire disaster happens, the closed spray head detects the fire disaster, the water flow indicator reports the fire area, and a flow switch or an alarm valve group or a pressure switch of the pressure stabilizing pump outputs a signal for starting the water supply pump to finish the starting of the system. After the system is started, the water supply pump supplies water to the open spray heads, and the open spray heads uniformly spray the water supply according to the water spray intensity not lower than the design specification, so that fire extinguishment is realized. Because the places with the temperature often lower than 4 ℃ have the danger of freezing the water filled in the pipe, and the places with the temperature higher than 70 ℃ have the danger of damaging the pipeline due to the aggravation of the vaporization of the water filled in the pipe, the wet system is suitable for being used in the environment with the temperature not lower than 4 ℃ and not higher than 70 ℃ (except the places which can not be rescued by water); automatic nozzles of glass ball closed type are generally used in wet systems. The explosion bottle type automatic spray head is filled with alcohol and sprays water to extinguish fire after explosion at a preset temperature.

The automatic vitreous body sprayer consists of an installation base, a compression screw and the like, and is subjected to a hydrostatic pressure sealing test of 1.2-3 MPa.

Fig. 13 shows an automatic vitreous body sprinkler head, which is connected to a pipeline by a screw connection portion 49, a glass body 45 is pressed by a pressing screw 44 through a screw hole 42 in a vitreous body mounting base 46, the vitreous body mounting base 46 is provided on a yoke arm base 48, a yoke arm 47 is connected to the periphery of the yoke arm base 48, a splash plate 41 is provided at the other end of the yoke arm 47, a tooth 43 is provided on the periphery of the splash plate 41, the vitreous body expands and is crushed by heat in case of fire, water flows out from the center of the vitreous body mounting base 46, the water flows onto the splash plate 41, and water is sprayed around the tooth 43, thereby achieving the effect of controlling the fire.

Dry, dry and wet (and pre-action if desired) sprinkler systems.

The dry-type fire extinguishing system is a closed automatic water spraying fire extinguishing system with the longest use history besides a wet-type system, and the dry-type automatic water spraying fire extinguishing system is produced on the basis of the dry-type system and aims to overcome the defect that the dry-type system is low in fire control and extinguishing rate. At ordinary times, the system pipe network is filled with pressurized gas, the system is a dry system, when a fire disaster happens, the pipe network is filled with pressurized water, and the system is a wet system. Dry, pre-action systems should employ either upright or drooping sprinklers.

The automatic spray head is a key component of the closed automatic water spraying fire extinguishing system and sprays water through the action of the heat sensitive release mechanism. It is composed of water jet, temperature-sensing releaser (controller) and splash plate, its shape and style are many, and fig. 3 is the automatic nozzle of common low-melting-point metal controller and the automatic nozzle of explosion bottle type.

The automatic nozzle of the low-melting-point metal controller is used for an automatic spray head which is used for melting and spraying water at a preset temperature outdoors in underground garages and places which are easy to freeze,

automatic water spray control principle:

the working principle flow chart of the automatic water spraying fire extinguishing system is filled with pressure water in the upper pipeline and the lower pipeline of the alarm valve, when a fire disaster happens, because the ambient temperature of a fire scene rises, liquid in the glass ball of the closed type spray head expands, the glass ball bursts, and the spray head is opened to spray water, so that the fire extinguishing is started. The water in the pipe network changes from static state to flowing state, the water flow indicator is sensed by the flowing water and then acts to convert the water flow signal into an alarm signal, the alarm signal is sent to the controller, and the alarm controller indicates that a certain area is spraying water. The shower nozzle lasts the flow switch action warning of spraying water and starting high-order fire water tank outlet pipe and opens the fire pump, perhaps cause alarm valve upper portion water pressure to be less than lower part water pressure, when this kind of pressure difference reaches a definite value, the valve block that originally is in the off-state is automatic to be opened, the pressure water passes through alarm valve flow direction water injection system's main line and water distribution pipe, get into the delay timer through special tubule simultaneously, confirm through the time delay, get into water conservancy alarm bell and pressure switch, send audible alarm signal, simultaneously the pressure switch action, become switching value alarm signal with the signal of pressure decline, send into alarm controller and open the fire pump. Each floor is provided with a water flow indicator, each water flow indicator is provided with an input module, and after the input module receives an action signal of the water flow indicator, the action signal is transmitted to the alarm controller through a bus signal; and the action signal of the pressure switch is also transmitted to the alarm controller through the input module. The two paths of signals are programmed through host logic, the corresponding output module is instructed to start the spraying pump to pressurize, so that the pipe network continuously keeps a certain pressure, and the pump starting electric signals are fed back to the alarm controller through the input module and are displayed.
