Spray parameter test device

Abstract

The invention provides a spray parameter test device. The test device comprises a left box body, a middle box body and a right box body. Two ends of the middle box are in seal connection with the right end of the left box body and the left end of the right box body. A spraying inlet is arranged in the left end of the left box body. A length scale and a spray diffusion angle scale, which performing marking by taking a middle line of the box body as a standard and the left end middle line starting point of the left box body as a marking original point are arranged the front face of the test device body. The length scale and the spray diffusion angle scale penetrate through the left box body, the middle box body and the right box body. The box walls of the left box body and of the right box body are made of hard transparent materials. Dray powder recycling mouths are arranged in the bottoms of the left box body and the right box body. The middle box body is of telescoping type transparent structure. The test device is capable of simply, easily and effectively testing spraying angle, effective spraying distance and the biggest spray distance of a spraying head during nitrogen dry powder mixed spraying or water spraying, and also recycling and reusing the sprayed dry powder extinguishing agent during the test process, so pollution to environment is reduced, waste on resources is reduced and spraying states in the box body can be observed more directly.

Description

Technical field: [0001] 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. Background technique: [0002] 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 time, if the d...

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

[0003] 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
