Description

Technical Field

[0001] The utility model relates to the technical field of fire sprinkler heads, in particular to a novel fire branch pipe sprinkler head. Background Art

[0002] Fire sprinkler heads are used in fire sprinkler systems. When a fire occurs, the temperature of the flame causes the material in the glass tube to reach its melting point and begin to expand, then burst the glass tube. The copper block originally supported by the glass tube in the fire sprinkler head immediately falls off, and water flows out of the pipe of the fire sprinkler head.

[0003] Since the glass tube is fragile, when a non-fire accident occurs, the glass tube will burst, the copper block will fall off, and water will spray out of the pipe. It is not easy to close it in time, and water resources will be wasted. At the same time, the size of the nozzle connected to the internal shell of the upper branch pipe is fixed. When different types of nozzles need to be connected, a size conversion head must be used for connection, which increases the cost, makes the operation cumbersome, and consumes manpower.
