Why are upright sprinklers used?
Why are upright sprinklers used?
Upright sprinklers are used mostly in places where obstructions may block water spray during a fire, and their height allows them to aim water around possible obstacles.
What is an upright sprinkler?
What is an upright sprinkler head? Upright fire sprinklers spray water upward to a concave deflector, producing a dome-shaped spray pattern. They install deflector-up to cover specific areas and to prevent ice and debris from collecting in the head.
Where do you use upright and pendent sprinklers?
Upright sprinklers are installed with deflectors above the sprinkler, while pendent sprinklers have deflectors below the sprinklers. Common industry practice is to use upright sprinklers in areas without finished ceilings and pendent sprinklers in areas with finished ceilings.
Which type of sprinkler head has the most aesthetically pleasing appearance?
The escutcheon does not cover over the sprinkler head, but fits around it, filling the gaps between the sprinkler head and the ceiling to give it a more finished and aesthetically pleasing appearance.
How do sprinklers work?
Fire sprinklers are very simple. Heat from a fire will break a glass tube or melt a solder plug which releases the water. The water comes out as a spray that covers the area immediately around the sprinkler, putting out the fire. Only the one sprinkler closest to the fire opens.
What is pendent type sprinkler?
HD Pendent Sprinkler is a small, thermosensitive, glass-bulb spray sprinkler available in several different finishes and temperature ratings to meet design requirements. During fire, the heat-sensitive liquid in the glass bulb expands, causing the glass bulb to shatter. …
How does pendent sprinkler work?
Fire sprinklers work because high heat triggers the sprinkler system. When a blaze ignites, the air directly above it heats rapidly. Most sprinkler heads feature a glass bulb filled with a glycerin-based liquid. This liquid expands when it comes in contact with air heated to between 135 and 165 degrees.
How many sprinkler heads can you put on one line?
At different pressures, the sprinkler head and nozzle will consume different amounts of water. For example, at 35 pounds per square inch (PSI) the 5000 Series Rotor using the 3.0 nozzle will use 3.11 gallons per minute (GPM). If your home’s water capacity was 10 GPM, you could place 3 heads per zone.
What should I look for in a sprinkler system?
Adjust pressure. If the pressure running to your sprinklers is too high, it will produce a mist instead of droplets. Mist can easily be carried off by the wind, wasting water, so you want to be sure that pressure is low enough to produce droplets but high enough to deliver water where it needs to go.
How do sprinklers move?
The oscillating sprinkler works on the principle that water provides the power to move the elliptical cam (or heart-shaped cam in some models) which moves the sprinkler arm. Water spins a simple turbine which must be attached to a series of gears stacked up (called a gear train) to slow down the speed of the water.
What are the benefits of Quick Response Sprinklers?
They have similar fire-control benefits as a standard response sprinkler, but their mission is slightly different. A quick response sprinkler discharges water higher on the walls to keep the fire from climbing and maintain lower ceiling temperatures.
What is a upright sprinkler head?
Upright sprinkler heads are efficient at dispersing water between obstructions. Thus, they are frequently used for rooms that are inaccessible, such as mechanical rooms, and in warehouses and industrial spaces. They are also often applied in structures with open ceilings.
What is the standard size of a sprinkler system?
Sprinkler Identification Number Standard SD1015, SD1010 (bulb 5mm), Quick Response SD1030, SD1032 (bulb 3mm) Style Upright Sprinkler SD1015, SD1032, Pendent & Recessed Pendent SD1010, SD1030 K Factor 5.6gpm/psi½. (80lpm/bar½) Response Time Index (RTI) Standard 50 Quick Response 30 Nominal Thread Size ½”NPT(15mm) Orfice Size 13mm Max.
What are the different types of upright fire sprinklers?
Many upright sprinklers are also available with the smaller 5.6K orifice, including Tyco’s TY-FRB series and Victaulic’s V27 series and VK300 models. But while upright fire sprinklers are a mainstay of nearly all fire sprinkler manufacturers, not all upright fire sprinklers are created equally.
