Difference between upright sprinkler head and pendent sprinkler head

1.Different purposes:

the upright sprinkler head is used in places without suspended ceilings, and the distance from the ceiling is 75MM-150MM. The top cover plays a part of the heat collection function, and about 85% of the water is sprayed downward. The pendent sprinkler headis the most widely used sprinkler head, which is used in spaces with suspended ceilings. The sprinkler head is arranged under the suspended ceiling. The pendent sprinkler head water is parabolic in shape, spraying 80~100% of the total water volume to the ground.

2.Features are different:

the upright sprinkler head and pendent sprinkler head cannot be used universally because of their different structural forms. The lower sprinklers are generally used in spaces with suspended ceilings, while the upright sprinkler head are used in spaces without suspended ceilings.

3.Different uses:

The upright sprinkler is parabolic in shape, spraying 80~100% of the total water down, and some of the water is sprayed to the ceiling. The pendant sprinkler is the most widely used sprinkler, which is installed on the branch water supply pipe. The shape of the sprinkler is parabolic, and 80~100% of the total water volume is sprayed to the ground.

4.Precautions for use of fire sprinkler

The sprinkler head shall be arranged under the roof or ceiling where it is easy to contact the hot air flow of the fire and is conducive to uniform water distribution. When there is an obstacle near the sprinkler, it should comply with the specification, or add a sprinkler to compensate for the spray intensity. This is one of the precautions when installing the fire sprinkler head.

The arrangement of vertical and pendent sprinklers, including the spacing between sprinklers on the same water distribution branch pipe and the spacing between adjacent water distribution branch pipes, shall be determined according to the water spraying intensity of the system, the flow coefficient of the sprinkler and the working pressure, and shall not be greater than the specified value, and shall not be less than 2.4 m. The distance between the splash tray and the roof for early suppression of quick reaction sprinklers shall comply with the regulations.
