文档介绍:船用空调通风系统安装施工工艺规范
INSTALLATION AND CONSTRUCTION TECHNICAL RULES
FOR MARINE AIR CONDITIONER & VENTILATION SYSTEM
一、概述:
ﻩGeneral
空调及通风系统中需要采用预隔热螺旋风管、单层螺旋风管、镀锌薄板矩形风管、板材焊接风管(钢质风管)及通风附件等,根据设计要求,落实风管及附件规格型号、数量,采用螺旋风管、镀锌方风管或板材焊接风管,严格按风管制作工艺和规范要求执行生产安装.
The air conditioner and ventilation system shall adopt the pre-insulated spiral air duct, single layer spiral air duct, galvanized sheet rectangle air duct, plate welded air duct (steel air duct) and ventilation accessories etc. According to the design requirements to determine the type and quantity of air duct and accessories, and select the suitable air duct, 。 spiral air duct, galvanized sheet square air duct or welded air duct。 According to the relative constructure technical rules to manufacture and install.

三、风管制作
Manufacture the air duct
(1) 镀锌矩形风管
  Galvanized rectangle air duct
镀锌矩形风管连接可采用翻边、铆接和焊接,风管与角钢法兰连接时,风管壁厚小于1。5mm,一般采用翻边铆接,翻在法兰的外侧,用角尺靠在风管的纵向折角边上,使风管中心线与法兰平面保持垂直,翻边的尺寸应为6-9mm。法兰用料规格较小的可取上限值,规格较大的取下限值,防止翻边卡住螺孔,影响组装,咬口重叠处,翻边时应将突出部分铲平,同时四角不应出现豁口,以免漏风,铆钉距离不可大于120mm。
Connection of rectangle air duct the flanging, rivet jointing and welding can be adopted, the connect the air duct and angle steel flange, when the thickness of air duct is less than , generally, flanging and rivet jointing can be adopted, at first the air duct shall be turned over the outside of the flange, and the center of air duct and the surface of flange shall keep verti
