The composition of the automatic water sprinkler system, the composition and principle of the sprink

The automatic sprinkler system consists of:

1 System components (collectively referred to as special products such as sprinklers, sprinkler guards, valves, hydraulic alarm bells, pressure starters, water flow indicators, etc.).

2.Monitoring and alarm control devices.

3.Fire pumps.

4.End water test device.

5.Pipe networks.

The composition and principle of the sprinkler system: usually the roof fire water tank is filled with water, when a fire occurs, the sprinkler head is chrome-plated and melted after the temperature reaches a certain temperature (generally 68 °C), and the water in the pipe is automatically sprayed out under the action of the water pressure of the fire water tank, at this time, the wet alarm valve is automatically opened, and the pressure switch in the valve is automatically opened, and the pressure switch has a signal line and the fire pump is interlocked, and the sprinkler pump provides the water of the pool to the pipe network through the pipeline, and the whole fire protection system begins to work.

The sprinkler system can be divided into a separate piping system or combined with the fire hydrant fire protection system, but it is not allowed to be connected to the domestic water supply system. The automatic sprinkler fire protection system consists of a sprinkler head, a fire pipe network, a control signal valve and a water source (water supply equipment).

For example, at 7:55, we will introduce how to calculate the angle between the hour and minute hands (angles greater than 180° are not considered). Knowledge Prep:

1) An ordinary clock is equivalent to a circle, and its hour or minute hand is equivalent to walking 360°; (2) The angle corresponding to each large block on the clock (one hour of the hour hand or five minutes of the minute hand) is: 360° 12 = 30 °; 3) The corresponding angle of the hour hand for every 1 minute should be: 360° (12x60)=; (4) The angle corresponding to the minute hand for every 1 minute should be:

360° 60=6 ° The calculation starts at 12 o'clock for the hour and minute hands. Since the minute hand is in front of the hour hand, you can first calculate the angle at which the minute hand has traveled, and then subtract the angle at which the hour hand has traveled, and then you can find the degree of the angle between the hour hand and the minute hand.

The angle at which the minute hand travels: 55 6° 330° The angle at which the hour hand travels is: 7x30°+ = then the degree of the angle between the hour hand and the minute hand is:

Summary. Good evening, the significance of sprinkler system design is to provide an automated means of fire extinguishing for buildings, factories, warehouses and other places. The sprinkler system can be automatically activated when a fire breaks out, and quickly spray fire extinguishing agents such as water mist or foam to effectively control the fire and reduce the loss of people and property caused by the fire.

Dear, good evening, the significance of the sprinkler system design is to provide an automated fire extinguishing method for buildings, factories, warehouses and other places. The spray system can be automatically activated when a fire occurs, and quickly spray fire extinguishing agents such as water mist or foam to effectively control the fire and reduce the loss of personnel and property caused by the fire.

Sprinkler system design needs to consider several factors, such as the type, size, height, and usage of the building, as well as local fire regulations and standards. Designers need to select suitable sprinkler heads, pipelines, pumping stations and other equipment for the jujube chain according to these factors, and arrange them in combination with the rock ridge to ensure the reliability and efficiency of the system.

The design of the sprinkler system can not only improve the fire safety of the building, but also reduce the damage to people and property caused by fire, and reduce the loss of disaster damage. Therefore, the significance of the sprinkler system is very important, and it has an important role in ensuring the fire safety of the building.

The significance and application value of sprinkler system design.

The application value of the sprinkler system is very high. First of all, the sprinkler system can be quickly activated when a fire breaks out, and the fire extinguishing agent can be automatically sprayed, so as to effectively control the fire and reduce the losses caused by the fire. Secondly, the sprinkler cover system can make a noise and carry out preventive spraying before the fire occurs, spraying the fire extinguishing agent on the surface of flammable objects, effectively reducing the probability of fire.

In addition, the sprinkler system can also be applied in industrial production, such as the spray cooling system can reduce the temperature of machinery and equipment and improve production efficiency.
