专注通风管道加工·排烟罩

The materials of plates, profiles and other primary products used in the manufacturing of air ducts and equipment, and the planning and manufacturing of ventilation ducts should conform to the rules of the planning and the current specifications of the relevant products, and the factory inspection certificate should be used. The materials should be inspected according to the current relevant specifications when leaving the site.

在通风管道设备的时分要关于风管的方位，高度，走向都要进行规划好，在风管的直径上面要求能够确保关于空气的更新的速度。

The orientation, height and direction of the air duct should be well planned during the time of ventilation duct equipment. The diameter of the air duct should ensure the speed of air renewal.

关于风管的联接部分，要进行紧密联接，所选用的垫片的厚度应该不小于3mm,垫片不该凸入管内,亦不宜杰出法兰外。关于金属性的风管在转弯的时分要遵照严厉的设备要求。关于塑料软管在弯道时要留神不该该有死弯或许塌陷。

The connection part of the air duct shall be tightly connected. The thickness of the gasket selected in the center shall not be less than 3mm. The gasket shall not protrude into the pipe or outside the outstanding flange. The metal air duct shall comply with strict equipment requirements when turning. Be careful not to have a dead bend or collapse when the plastic hose bends.

风管设备前,应内、外杂物,并做好清洁和保护作业。一同关于风管的联接部分的螺丝的方位要尽或许的便当往后的修理。

Before the air duct equipment, the sundries inside and outside shall be cleaned and protected. The orientation of the screws on the connecting part of the air duct should be as convenient as possible for future repair.

通风管道作业时，会将外界新鲜空气顺畅带入室内。如在日常日子中或自界说场景发生的条件下,人们通过通风管道然后确保一些有烟雾或环境中一氧化碳通过空气流转得到稀,然后不让人们被有害气体烦扰。

When the ventilation duct works, it will smoothly bring the outside fresh air into the room. For example, in daily life or under the conditions of self-defined scenes, people pass through the ventilation ducts and then ensure that some smoke or carbon monoxide in the environment is diluted through air circulation, and then do not let people be disturbed by harmful gases.

通风管道的联接办法有灵敏和多样化,因为它的环绕玻璃钢管道接头办法呈现不同的特色,使它在详细的施工条件的根底上,能够更大程度上增加管道联接的灵敏性,然后前进项目自身的牢靠性。

The connection method of the ventilation pipe is sensitive and diversified, because its connection method around the GRP pipe presents different characteristics, which enables it to increase the sensitivity of the pipe connection to a greater extent on the basis of the detailed construction conditions, and then advance the reliability of the project itself.
