Abstract

The invention provides a leakproofness test device for an HVAC pipeline. The leakproofness test device comprises a test tube A, a pressure gauge A, a test tube B, a pressure gauge B, a cleaning drum,a step groove, a top cover and agitating blades; the test tube A transversely penetrates out of a device body, and the test tube A is respectively connected with a first control valve and a second control valve; the test tube B further transversely penetrates through the device body, and the test tube B is connected with a third control valve; the two ends of the cleaning drum are respectively connected with an inlet pipe and an outlet pipe; horizontal pipe ends of the inlet pipe and the outlet pipe are connected with an on-off valve; a small motor is fixed in the middle of the top of the topcover through bolts, a stirring shaft is connected to the bottom of the small motor, and a plurality of groups of agitating blade are welded on the stirring shaft. Cleaning liquid can be added througha feeding hole, and the cleaning liquid can be conveyed into the HVAC pipeline through water flow, so that the cleaning liquid can fully act on the HVAC pipeline, thus the cleaning effect of the HVACpipeline can be improved, HVAC leakage test can be carried out, and the HVAC can also be cleaned.

Description

technical field [0001] The invention relates to the technical field of heating and ventilation pipeline testing, and more specifically relates to a leak-proof testing device for heating and ventilation pipelines. Background technique [0002] Nowadays, the heating pipes in many buildings are laid underground. It is often necessary to test the tightness of the heating and ventilation pipes before decoration to test whether there are leaks in the heating and ventilation pipes to ensure normal heating in the later period. [0003] For example, in the patent application number: CN201320261925.2, a fully automatic pipeline testing machine is disclosed, which includes a control machine and a water tank connected by a pipeline, and the pipeline is provided with a water inlet and an outlet for connecting the pipeline to be tested. The water outlet, the controller, the pipeline, the pipeline under test and the water tank form a circulating waterway; the pipeline is also provided with...
