Heating and ventilation equipment hard pipeline air leakage detection device

Abstract

The invention discloses a heating and ventilation equipment hard pipeline air leakage detection device, which comprises a first sleeve and a second sleeve, wherein the right side bottom of the first sleeve and the left side bottom of the second sleeve are respectively provided with a first connector and a second connector; the right side top of the first sleeve and the left side top of the second sleeve are respectively connected with a connecting sleeve through a first threaded rod and a second threaded rod; a threaded hole is formed inside the connecting sleeve; the first threaded rod and the second threaded rod are respectively connected at the left side and the right side inside the threaded hole through screw threads; an inflating device is arranged at the left side of the outer part of a water tank, and communicates with the first connector through a hose. The device has the advantages that a hard pipe is connected in a sealed way through the first connector and the second connector, and is then put into water; the inside of the hard pipe is inflated through the inflating device; whether air leakage exists or not is judged through judging whether bubbles are generated in the clear water or not, so that whether the hard pipe is qualified or not can be detected. The cost of the device is low; the operation is simple; the mass production is easy.

Description

technical field [0001] The invention relates to the technical field of heating and ventilation, in particular to an air leakage detection device for hard pipes of heating and ventilation equipment. Background technique [0002] HVAC equipment has been widely used in buildings in recent years to provide heating, ventilation, air conditioning and other functions to make the indoor air more comfortable and livable. HVAC equipment often needs to use hard pipes during the installation process. Once the hard pipes leak, it will easily lead to energy waste and cause certain losses. During the production of pipelines, it is necessary to perform air leakage detection on hard pipes. The existing The cost of air leakage detection equipment is high, and it is not easy to be mass-produced and popularized. Therefore, an air leakage detection device for hard pipes of HVAC equipment is proposed. Contents of the invention [0003] The object of the present invention is to provide an air l...
