Abstract

The invention discloses a temperature sensing mechanism of a large-diameter spray nozzle. The mechanism comprises a temperature sensing trigger device, a first storage chamber, positioning stairs anda glass ball, wherein a first supporting leg, a second supporting leg, a third supporting leg and a supporting edge are disposed on a supporting frame, and stabilization tongues bent to the first supporting leg are symmetrically disposed on two ends of the supporting leg; a guide groove is formed in one end of a press block, a threaded hole is formed in the other end, and a shoulder part fitted with the stabilization tongues is disposed at the middle part; a second storage chamber is disposed on a glass ball screw; and the glass ball can sense temperatures, one end is mounted in the first storage chamber, and the other end is mounted in the second storage chamber. The large-diameter spray nozzle comprises a spray nozzle body, an end cap and a conical screw, wherein a water outlet channel and a spray nozzle frame are disposed on the spray nozzle body, the end cap is disposed on a water outlet end face of the water outlet channel, the conical screw is screwed on the spray nozzle frame and is coaxial with the end cap, and the large-diameter spray nozzle also comprises the temperature sensing mechanism.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a large-diameter nozzle temperature sensing mechanism and the large-diameter nozzle. Background technique [0002] In the fire extinguishing equipment, the fire sprinkler is the main device, which directly faces the fire scene. The existing fire sprinkler mainly uses glass bulbs (tubes) or fusible alloys as the sensing temperature and trigger release elements. It is applicable to fire sprinklers, but in large-flow fire sprinklers, due to the large diameter of the pipe, the pressure of the fire-fighting fluid on the plug (also called a seal) on the body is large, and the ordinary temperature-sensitive glass ball (tube) support structure It cannot be tolerated. If the diameter of the temperature-sensing glass bulb is increased, there will be a disadvantage of large heat capacity, poor temperature-sensing effect and slow response speed. Therefore, a structure using a...
