Description

Technical Field

[0001] The utility model relates to the technical field of flue check valve installation mechanisms, in particular to a flue check valve installation mechanism. Background Art

[0002] As we all know, the flue check valve refers to the check valve installed at the flue outlet. Generally, the builder will equip it when handing over the house. The actual vent is equipped with a metal baffle with an eccentric shaft. This structure makes it difficult to achieve complete reverse sealing. Most of the check valves currently sold on the market are check valves installed at the flue outlet.

[0003] At present, the installation methods of flue check valves on the market are mostly gluing or drilling holes in the wall and installing expansion screws. The gluing method is not durable and firm, and the drilling and installing expansion screws are prone to cause cracks in the wall or tiles, resulting in secondary decoration losses, and cannot meet the use requirements. Therefore, we propose a flue check valve installation mechanism to solve the above-mentioned problems. Utility Model Content
