Sprinkler sprinkler sprinkler as an element of fire extinguishing system

When building new premises, as well as overhauling old ones, it is necessary to provide for the installation of fire safety systems. The most effective are modern systems using sprinkler sprinklers.

Appointment

Sprinkler - sprinkler, which is an irrigation head, mounted in the water pipe system . Such an installation is called sprinkler and is most often used in fire extinguishing equipment in various premises. In the network of pipes, air or water is constantly under pressure. Sprinkler Sprinkler Sprinkler has a hole that is sealed using a thermal lock or a thermosensitive bulb. Their operation occurs at certain temperatures in the range from 57 ° C to 343 ° C.

Operating principle

When the room temperature rises and reaches the value necessary for the sprinkler to operate, the lock is decoupled, or the bulb bursts, and irrigation of the protected area begins. The response time of the low-temperature sprinkler is no more than 300 seconds, and the high-temperature sprinkler is 600 seconds. Usually the spraying in the fire starts 2-3 minutes after the room temperature rises. In the opinion of specialists, sprinkler water sprinkler has a serious drawback: such a response time is a rather high inertia for fire fighting.

Main Features and Types

Sprinkler Sprinkler Sprinkler in its design has made of heat-resistant materials housing, outlet and screw. Disruptive heat-sensitive devices can be different - a bulb or a lock. The most important technical characteristics of sprinklers include irrigation intensity, flow rate, and irrigation area. The sprinkler body is usually brass, but can also have a polymeric white chrome or nickel plated coating.

Depending on the location for vertical installation, the following sprinklers are different: sprinkler sprinkler with water outlet down and sprinkler with a water outlet up. There are models that, under different operating conditions, can be installed both by a socket down and up.

In addition, there are sprinklers, for which a horizontal installation is also possible. Such a sprinkler is called a "water sprinkler universal sprinkler". In any installation, water is sprayed along a spherical path, half of the stream is sprayed down, the other part is reflected from the outlet upwards. One such sprinkler allows you to extinguish fires of varying degrees of force in a 12 square meter area and prevent damage to property.

There are models for more effective protection of objects using foam. Moreover, the supply of water or foam is carried out only in hazardous areas with increased temperature, and the water discharge is significantly reduced.

Installation

Any work that involves the installation and operation of sprinklers should only be carried out by specialists. Personnel must have access to work with pipelines operating under pressure and comply with all requirements of GOST.

In installations filled with water, the sprinklers are mounted vertically and can be located either with a socket up or with a socket down. In air systems - only rosettes top, so that in case of freezing accumulated condensate there is no damage to the bulb.

The installation of sprinklers is carried out at the end of all installation work through the pipeline. Tighten the sprinklers with a special key with medium effort so as not to deform the threaded connection and the sprinkler outlet.

The use of sealing material is mandatory to ensure the tightness of the threaded connection. It must be ensured that the seal does not enter the opening of the sprinkler. In places where there is a high probability of mechanical damage to sprinklers, they must be covered with rigid wire gratings.

Service

In order to ensure that the fire extinguishing system is in working condition continuously, it is necessary to regularly inspect it.

Each sprinkler sprinkler must be checked for corrosion and damage. It must be ensured that there are no obstacles to irrigation, and the sprinkler cover is not damaged.

It is necessary to have spare sprinklers, in order to quickly replace the damaged sprinkler sprinkler sprinkler with water sprinkler. The used sprinklers are unsuitable for repair or reuse, they must be changed.

Before replacing, the fire extinguishing system is switched off, the pressure in the unit is completely relieved, the water is drained and the old sprinkler is dismantled.

Before installing a new water sprinkler sprinkler, make sure that it is fully compatible with this fire-fighting system, has the required design, temperature and response time. Once everything has been done, the system is again set to standby. The service life of the sprinkler is 10 years from the date of production.

Sprinkler sprinkler water greatly increases the effectiveness of fire extinguishing systems, allows timely start firefighting and while significantly saves water.
