Processing method of fire sprinkler cooling device

Abstract

The invention proposes a processing method for a fire-fighting spray cooling device. Processing steps: 1. Weld flanges at both ends of the straight pipe; 2. Put the straight pipe after welding the flange on the pipe bender and bend it according to the design arc to make an arc bend; 3. On the arc bend Drill holes according to the angle, spacing and aperture required by the design; 4. Use the self-heating rotary extrusion die to perform rotary extrusion and stretching on the drilled holes to make the nozzle interface; 5. The nozzle after extrusion and stretching Sprinkler interface threads are processed in the interface to make nozzle interfaces with connection threads. In this method, the flange is welded on the straight pipe first, and then the pipe is bent, and the nozzle interface is formed by hot extrusion and stretching on the curved pipe. It has the advantages of less processing links, easy to grasp the processing position, reducing the consumption of working hours, reducing labor intensity, and ensuring the processing quality. It is suitable for production and processing of fire sprinkler cooling devices and other fire fighting equipment.

Description

technical field [0001] The invention proposes equipment in the field of fire protection, specifically a processing method for a fire protection spray cooling device. Background technique [0002] Before the present invention was proposed, there was a widely used device for fire spraying and cooling. Its structure was as follows: a plurality of sections of arc-shaped pipes were connected to each other through flanges to form an annular spray pipe, and the nozzle connecting pipes were welded one by one on the spray pipe. , the pipe is used for passing water, and the nozzle is used for spraying. This spray cooling device is usually installed and covered on the upper part of the flammable product. Once the temperature of the flammable product is too high or there is a burning phenomenon, the water valve is opened, and the high-pressure water passes through the arc tube and the nozzle. Spraying, it can extinguish the fire with water or cool down the flammables, so as to eliminat...
