Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology, specifically to an airtightness testing device for a gas transmission pipe. Background Technology

[0002] Household gas pipelines are key facilities for ensuring the supply of gas for daily cooking, hot water, and other domestic needs. They are usually made of metal or corrosion-resistant composite pipes buried underground or in walls. After being connected to the municipal gas network or gas cylinder, the gas pressure is stabilized by a pressure regulating device and then delivered to gas usage points such as kitchens and bathrooms through branch pipelines. The pipeline connections are sealed to prevent leaks and are equipped with gas meters to measure usage.

[0003] Chinese patent discloses an airtightness testing device for gas transmission pipes (publication number: CN218823002U). This device, by pushing a push rod, allows gas from a gas storage tank to enter the gas transmission pipe through a fixed tube. It then observes whether air bubbles are generated around the outside of the pipe. If bubbles are generated, the airtightness of the gas transmission pipe is substandard; otherwise, it is up to standard. This device allows for a relatively quick and intuitive assessment of whether the airtightness of the gas transmission pipe meets the standard. However, this device has the following drawbacks:

[0004] The aforementioned airtightness testing device occupies a large space, making it inconvenient to test gas pipelines in narrow spaces. Furthermore, the device can only test vertically oriented pipelines, making it inconvenient to temporarily test the airtightness of horizontally extending gas pipelines. Therefore, an airtightness testing device for gas pipelines is proposed to solve the above problems. Utility Model Content

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An airtightness testing device for a gas pipeline includes a container mechanism, and a sealing mechanism is provided above the container mechanism.
