Detailed Description

As shown in fig. 1, 2 and 3, the air duct connector comprises a wall-through pipe 1, wherein one end of the wall-through pipe 1, which is positioned in a clean room 4, is connected with a connecting pipe 2, and the connecting pipe 2 is used for being connected with an air duct 3-1 of an animal cage 3; one end of the through-wall pipeline 1, which is positioned outside the clean room 4, in the technical interlayer is connected with a reducer pipe 5, and the end part of the reducer pipe 5 corresponds to the size of the variable air volume valve 6; the wall-penetrating pipeline 1 comprises an inner wire pipe 1-1 and an outer wire pipe 1-2 which are connected with each other in a threaded manner, wherein threads are arranged inside the upper end of the inner wire pipe 1-1, threads are arranged outside the lower end of the outer wire pipe 1-2, and blocking pieces 1-3 are respectively arranged at the lower end of the inner wire pipe 1-1 and the upper end of the outer wire pipe 1-2. The end part of the reducer pipe 5 is provided with a flange 5-1, and the reducer pipe 5 is connected with a variable air volume valve 6 through a flange; the reducer pipe 5 and the outer wire pipe 1-2 can be connected by welding, and the inner wire pipe 1-1 and the connecting pipe 2 can be connected by welding.

When the cleaning device is used, the inner wire tube 1-1 and the outer wire tube 1-2 are in threaded connection, so that the two blocking pieces 1-3 can be tightly attached to a wall or a color steel plate to improve the sealing performance, and components such as sealing rings and the like can be further added to further improve the sealing performance of the clean room 4; the groove 2-1 is formed at the joint of the connecting pipe 2 and the ventilating duct 3-1 through ribbing treatment, so that the connecting pipe can be conveniently connected with the ventilating duct 3-1, the wall-through pipe 1 and the connecting pipe 2 are selectively welded, the welded joint is passivated after welding, the attractiveness of the welded joint is ensured, and other welded parts can also adopt the method; the diameter of the connecting pipe 2 is 89mm, which is beneficial to the installation and fixation of a hose of DN90, and the diameter of the reducing pipe 5 is 200mm after reducing, which is suitable for the installation of most Venturi valves; the components can be made of stainless steel, so that the appearance is good; meanwhile, the flange connection of the reducer pipe 5 and the variable air volume valve 6 can facilitate installation and subsequent maintenance.
