shenzhen's sharp share duct under soft connection with the masses of users, fan soft connection, canvas duct soft connection some problems during construction:
1, should be selected according to the specification and design documents anti-corrosion, moisture-proof, breathable, mildew, does not produce dust, not easily aging, meet health requirements, harmless to human and animal, have a certain strength and flexibility of the environmental protection material.
2, ventilation engineering soft joint material should meet the requirements of the code for fire protection.
3 soft connection, air ducts, fan soft connection, soft canvas duct connections as air conditioning and ventilation system of pipes, duct is used to partition the rigid connection of the appropriate length is 150 mm to 300 mm, vibration isolation and displacement compensation effect, the joint should be tight, solid and reliable, and after the installation should have certain scale, and should be no defects such as crack, distortion.
4 soft connection, air ducts, fan soft connection, canvas duct insulation filling in soft connection should use material combustion rating is class A1, and thermal insulation materials shall not be leakage.
5 soft connection, air ducts, fan soft connection, canvas duct soft connection may not be as nature round place, variable diameter tube end interface after a connection part use or equipment, flexible short tube of two end face shape should be same size, on both sides of the flange should be parallel.
6 soft connection, air ducts, fan soft connection, canvas duct with the Angle steel flange connection, the soft connection can use galvanized steel bar layering way, through the rivet connection. Layering flanging appropriate for 6 mm to 9 mm, close to the Angle iron flange rivet connection, smooth, the appropriate rivet spacing is 60 mm ~ 80 mm.
7 soft connection, air ducts, fan soft connection, canvas duct soft connection flange specifications and duct flange specifications should be consistent.
8 soft connection, air ducts, fan soft connection, the flexible canvas duct soft connection use fabric material, thickness, layer number, etc should be accord with the requirement of design and the corresponding specification, atlas. 9, construction, should strengthen the finished product protection of soft connection, avoid sharp, hard object scratches and welding sparks to its damage.
