Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to pressure test performance detection equipment for water heating pipes. Background Art

[0002] Floor radiant heating is a heating method that uses hot water with a temperature not higher than 60°C as a heat source. It circulates in a coil system buried under the floor, heating the entire floor and radiating heat evenly into the room through the ground.

[0003] However, the existing coil system buried under the floor usually uses hot water during use. Therefore, during the sampling pressure test of the water heating pipe, it is also necessary to test whether the device has airtightness problems; therefore, during the test, the two ports of the water heating pipe need to be sealed, and the existing ports are generally sealed by welding or mechanical bolts.
