Drainage installation process:


60mm brass tube


Drainage installation technical requirements:

1、Drainage and flange,It should be checked whether the outer diameter of the duct or the outer length and the deviation of the inner side size of the flange meet the requirements.。Connection,The flange plane must be kept vertically with the wind tube.。

2、Drainage system before installation,Whether the highlights of the wind tubes and components should be further verified.,At the same time, closely follow the site changes,Once the situation in the on-site line conflict should contact professional engineers in time。

3、Denar positioning instrument to determine the boom position before the air is installed,Use this instrument to do only one midline positioning,Synamerically installed in the center line of the duct,The spacing between the insulation duct double boom is larger than the air tube specifications.120mm(Barbing wind tube edge60mm),The spacing between the two booms between the warm air tube is larger than the air tube specifications.60mm(Barbing wind tube edge30mm),Pay attention to the position of the air in the flange。

4、Drainage,The level of the wind pipe center line must be maintained,Install a horizontal measurement level after installation。The horizontal level of the duct is allowed to deviate per meter should not be greater than3mm,The total deviation should not be greater than20mm。

5、Drainage,branch、Hang、The bay cannot be set in the air、Flange and other parts。Rectangular insulation air tube cannot be directly used、Hang、Bracket,Pad on the mat,The thickness of the pad is quite the thickness of the insulation layer.。Branch hanger and related accessories(Wood, etc.)To do related anti-corrosion processing(Pay attention to mat wood end anti-corrosion)。

(60mm brass tube)6、Mounting riser wire hammer,Ensure the verticality of the duct。

7、The nut connecting the flange should be on the same side,Connecting bolts should be galvanized bolts,At the same time, you must be equipped with the corresponding gasket and spring gasket.,The flange gasket should not convex into the wall of the exhaust,Never convex outside the flange。

(60mm brass tube)8、Use the chain of hoisting wind tubes,Require:①Do not stand in the wind tube,Command by professionals②Fixed point must be firm。

9、Drainage flanges cannot be inside the wall。

10、Wind tube bracket roots[8Galvanized tank,Length80mm。

11、Drainage,Drainage test should be performed on drainage test,method:①For large people to enter the air tube,After connecting a section,Both ends with carpets or wooden boards,Illuminate the exterior of the air tube,The inspection staff inspected the air tube flange connection and the wind tube bite site inside the duct:Acceptance requirements:Low pressure system,Every10Rice seam does not exceed2Leline point,Every100Meter does not exceed16Leline point,Striped light;Medium pressure system,Every10Rice seam does not exceed1Leline point,Every100Meter does not exceed8Leline point,Striped light②For small system wind tubes,Under the conditions of ensuring the darkness of the external environment,use36VThe low pressure light of the protective cover is slowly pulled up to the other end of the wind pipe from one end of the air tube.,Check light,Acceptance standards。General case,The leakage point is mainly in three links、Flange connection、Wind tube flaps four-corner part、Ticket short tube connection、Fan and other parts of the fan,Construction team should pay special attention。For leakage points,Application Sealant in the wind tube(Big duct)External blocking。

(60mm brass tube)12、For any size system,First, the wind tube can be opened after leaking.。

13、During the wind tube hoisting,The unconnected at both ends must be sealed with fireproof cloth,Antiture。

14、Fire valve installation requirements:The spacing between the fire valve and the wall is not greater than200mm,Big sideb≥630Fire valve set a separate branch

15、Ventilation air conditioning system Drainage flange sealed gasket adopts rubber sheet,Smoke or exhaust and exhaust exhaust flange sealed gasket adopts silicon-titanium alloy rubber sheet,Thickness3mm~5mm。

16、The gasket uses a wedge-shaped lap(As shown below),The width of the gasket should be with the flange,The gasket cannot be overwhelmed into the air inner,Avoid increasing resistance affecting ventilation,Repair for protruding gaskets。
