Embodiment Construction

[0020] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0021] The invention provides a pipeline air tightness detection device. Such as figure 1 and figure 2 As shown, the pipeline air tightness detection device includes a plugging part 10, a water tank 20 and an air inlet pipe 30. The plugging part 10 is used to seal the air outlet of the detected pipeline 80, and the plugging part 10 and the detected pipeline 80 are located at Below the liquid level in the water tank 20 , the air inlet pipe 30 communicates with the air inlet of the detected pipeline 80 . When using the pipeline airtightness detection device in the present invention, the worker needs to pass gas into the pipeline 80 to be tested through the air inlet pipe 30, and then observe whether there is any air leakage in each place of the pip...

Abstract

The invention provides a pipeline air tightness detection device comprising a plugging portion, a water box and an air inlet pipe. The plugging portion is used for sealing an air outlet of a pipeline to be detected. The plugging portion and the pipeline to be detected are arranged below the liquid level in the water box. The air inlet pipe is communicated with an air inlet of the pipeline to be detected. In use, the worker feeds air in the pipeline to be detected through the air inlet pipe and observes whether or not air leakage occurs to the pipeline to be detected, especially connectors; if no bubbles occur in the water box, air tightness of the pipeline to be detected is proved to be good and applicable to evacuation; if the air entering the pipeline to be detected becomes the bubbles on the water, the pipeline to be detected is proved to be poor in air tightness and fails to be used for evacuation. By sealing the air outlet of the pipeline to be detected by the plugging portion, the air never flees out of the air outlet of the pipeline to be detected, accordingly guaranteeing user reliability of the pipeline air tightness detection device.

Description

technical field [0001] The invention relates to the technical field of pipeline detection, and more particularly, to a pipeline airtightness detection device. Background technique [0002] After the outdoor unit of the air conditioner is assembled, a vacuum pump will be used to evacuate the system. Before vacuuming, it is necessary to connect all kinds of vacuuming hoses to the vacuum pump through multi-way pipelines (such as six-way pipelines). Therefore, whether the airtightness of the multi-way pipeline is good or not affects the effect of vacuuming and the work efficiency of vacuuming. If the airtightness of the multi-way pipeline is poor, the system cannot be vacuumed, or the residual air in the system is not exhausted. When the refrigerant is injected into the system, the residual air will affect the purity of the refrigerant, thereby reducing the energy efficiency ratio of the air conditioner. [0003] Take the six-way pipeline as an example. The six-way pipeline is...
