Abstract
Description
technical field
[0001] The invention relates to a vertical duct of an air duct or an air duct, in particular to a combined special tool for making pipe fittings for a ventilation, air conditioning, and smoke prevention system and a method for using the same. Background technique
[0002] The raw materials for the production of pipe fittings for ventilation, air conditioning and smoke control systems have so far been divided into two categories: metal and non-metal. Non-metallic materials are representative of inorganic cementitious composite materials, which are artificially pasted by using wooden molds. When making pipe fittings, first determine the specifications and quantities of the pipe fittings to be made according to the construction drawings, and then determine the number of sets of wooden board molds according to the requirements of the construction period. After the mold is made, the inorganic gelling material is stirred in the mixing equipment and then manually p...

Embodiment Construction
[0027] As shown in the figure, a special tool for making pipe fittings for ventilation, air conditioning and smoke prevention systems and its usage method. The pipe flange 7 and the tube sheet 6 can be assembled together accurately at one time by using the provided special tools. During the assembly process, the overall bonding condition can be achieved without repeatedly adjusting the verticality of the tube sheet 6 and the flange 7 .
[0028] When the special tool is combined with the pipeline, the position of the connecting plate 4 is on the inner side of the flange, and the flange 7 is tightly fixed on the connecting plate 4 through the pressing device 3 and the backing plate 2, so that the flange 7 and the connecting plate 4 become a whole. At this time, the connecting plate corrects and strengthens the flange. The tube plate 6 is installed on the top of the connecting plate 4, and the groove end is close to the flange 7, and it is integrated with the connecting plate 4...
