Spray parameter test device

Abstract

A spray parameter testing device, including a left box, a middle box and a right box, the two ends of the middle box are respectively sealed and connected with the right end of the left box and the left end of the right box. The front of the device is equipped with a length scale and a spray diffusion angle scale with the starting point of the center line of the left end of the left box as the mark origin and the center line of the box as the reference. The length scale and the spray diffusion angle scale run through the left box, the middle box and The right box, the left box and the right box are all made of hard transparent material as the box wall and the bottom is provided with a dry powder recovery port, and the middle box is a retractable transparent box. The present invention can not only simply and effectively test the spraying angle, effective spraying distance and maximum spraying distance of the nozzle when performing nitrogen dry powder mixed spraying or water spraying, but also can recycle and reuse the dry powder fire extinguishing agent sprayed out during the test, reducing the Environmental pollution, avoiding waste of resources, and at the same time, the spray situation inside the box can be observed more intuitively.

Description

[0001] Technical field: [0002] The invention relates to the technical field of fire protection, in particular to a spray parameter testing device used in a dry powder fire extinguishing system, a water spray fire extinguishing system and a water spray fire extinguishing system. [0003] Background technique: [0004] The large-scale dry powder fire extinguishing system is mainly composed of a power cylinder group composed of multiple high-pressure nitrogen cylinders (pressure about 15MPa), a dry powder gas storage tank and connecting pipelines. When working, the power bottle group is started, and the nitrogen gas decompressed to about 1 MPa enters the dry powder gas storage tank, mixes with the dry powder, and is sprayed to the target area by the nozzle through the connecting pipeline. At present, there is no clear measurement device for the parameters of dry powder spraying, such as the maximum spraying distance, effective spraying distance, spraying angle, etc. At the same...

AI Technical Summary

Problems solved by technology

At present, there is no clear measurement device for the parameters of dry powder spraying, such as maximum spraying distance, effective spraying distance, spraying angle, etc.

At the same time, if the dry powder in the test cannot be effectively recycled and reused, it will not only waste resources, but also the scattered dry powder may cause environmental pollution

[0005] Similar to the dry powder fire extinguishing system, the water sprinkler fire extinguishing system and the water mist fire extinguishing system both need to use nozzles, and the spray parameters of the nozzles, such as the maximum spray distance, effective spray distance, spray angle, etc., are also not easy to test at present
