Problems solved by technology

[0003] The common plate flange air valve is mainly used on the common plate flange air duct, and is generally made of iron plate or galvanized plate. Because of its multi-faceted three-dimensional structure such as flange, valve wall, and folded edge, in the traditional processing technology, Generally, after stamping or shearing multiple sheets, they are welded by riveting, jointing, etc. The process steps are many, the cycle is long, the efficiency is low, and the production cost is high; and due to the combination of multiple sheets, the overall strength Poor, variability, affects damper adjustment performance

Embodiment Construction

[0023] Such as figure 1 As shown, the galvanized sheet or white iron sheet is stamped or cut, and the excess part is removed, and the outer contour of the remaining sheet 11 is rectangular, forming four units distributed horizontally, and the four units pass through the upper and lower reserved folds 5 Connected as a whole; each unit includes a rectangular valve wall 1 and a trapezoidal flange 2 at the upper and lower ends. The four flanges 2 are of equal height, and the lower bottom angle is 45 degrees. The included angle of the lower bottom b (longer bottom) is provided with symmetrical half-holes on the adjacent flange 2; the separated units are a group with the same shape, and one group of valve walls 1 is formed by the flange 2 The upper bottom edge a is the width, and the buckle claws 6 are reserved on both sides, preferably 3 evenly distributed on each side, and three corresponding buckle holes 7 are opened on the valve wall 1 adjacent to it; the other group of valve wa...

Abstract

The invention discloses a co-plate flange air valve body which consists of a valve casing and flanges at both ends, wherein the outer sides of the flanges are provided with vertical folding edges, the valve casing is formed by splicing four valve walls, and each flange is formed by splicing flange edges; the valve walls, the flange edges and the folding edges which are positioned on the same surface are of an integral structure, and four folding edges positioned at the same end are of an integral structure; and the flange air valve body is manufactured by sequentially punching, bending and molding a plate. the flange air valve body has the advantages of simple process, high processing efficiency and low labor cost; and because the flange air valve body is molded by adopting one plate, and a plurality of buckling claws are adopted to fix, the flange air valve body also has the advantages of stable structure, high strength, difficult deformation and long service life.

Description

technical field [0001] The invention relates to the field of ventilation equipment, in particular to a damper used in ventilation ducts and a manufacturing method thereof. Background technique [0002] The air valve is an indispensable central air-conditioning terminal accessory in ventilation, air conditioning and air purification projects. It is generally used in ventilation pipes to adjust the air volume of branch pipes, and can also be used for mixed adjustment of fresh air and return air. It is widely used in industrial In factories and civil buildings. [0003] The common plate flange air valve is mainly used on the common plate flange air duct, and is generally made of iron plate or galvanized plate. Because of its multi-faceted three-dimensional structure such as flange, valve wall, and folded edge, in the traditional processing technology, Generally, after stamping or shearing multiple sheets, they are welded by riveting, jointing, etc. The process steps are many, ...
