Abstract
The utility model provides a double-face aluminium foil composite glass fiber cloth noise-absorbing hose, which is a flexible hose formed by an inner protective layer, an outer protective layer, a middle heat insulation layer and a middle reinforcing elastic spiral steel wire. The outer protective layer is a double-face aluminium foil composite glass fiber cloth, the inner protective layer is a micro-punch double-face aluminium foil composite glass fiber cloth which is formed by coating the two faces of the glass fiber cloth with aluminium foil, and the heat insulation layer is a glass fiber heat insulation cotton; moreover, an elastic steel wire is winded between the inner protective layer and the outer protective layer and is fixed on the fixing layer of the glass fiber cloth; the ends of the inner protective layer and the outer protective layer are contracted as integrity and sealed at the end through the zinking sheet iron batten. The utility model solves the problem of the exposed heat insulation cotton at the tube end, improves the noise-absorbing and sound-insulation performance as well as the surface intensity, and prevents tearing and puncturing, having characteristics of temperature resistant, corrosion resistant, inflaming retarding and damp protection as well as high extension and easy mounting, thereby being applicable to various air conditioning, dust discharging and ventilation systems.
Description
Technical field: the utility model relates to the pipeline that a kind of air-conditioning and ventilation system are used.
Background technique:
Along with the flexible heat-insulating airduct is popularized and used mondial, some defectives of existing flexible heat-insulating airduct also reveal: at first, body noise reduction, sound insulation property need to strengthen again; Moreover in the naked leakage of flexible pipe port connection part thermal insulation layer, the cellucotton that spills is not only easily by in workman's suction body, and installs to site operation and to make troubles; The single face aluminium foil surface is easy to be torn to shreds, puncture, and the elastic helix steel wire causes body intensity and guarantor, heat-shielding performance to reduce easily at the body superior displacement.
The purpose of this utility model is the noise reduction of reinforcement body, sound insulation property and body intensity, prevents that the surface is destroyed, solves the problem that the flexible pipe port leaks naked fiber cotton, on-the-spot installation inconvenience.
Technological scheme:
Two-sided aluminium foil composite glass fiber cloth Sound eliminating soft pipe of the present utility model; be by inner protective layer; external protection; middle thermal insulation layer and the middle flexible pipe body of strengthening elastic helix steel wire composition; it is characterized in that: external protection is two-sided aluminium foil composite glass fiber cloth; inner protective layer is the two-sided aluminium foil composite glass fiber of the micropunch cloth that evenly is covered with micropore; two-sided aluminium foil composite glass fiber cloth is that the two-sided cladded aluminum foil of glass cloth forms; thermal insulation layer is the spun-glass insulation cotton; between inner protective layer and thermal insulation layer, curl up flexible spiral wire; the elastic helix Fixation With Steel Wire is on the glass fiber cloth fixed bed; in; external protection shortens one in port position, seals in the port by the galvanized sheet iron press strip.
Above-mentioned inside and outside protective layer shortens one in port position, fixes at port and galvanized sheet iron interface by the galvanized sheet iron press strip.
Above-mentioned inside and outside protective layer shortens one in port position, fixes at port and flange by the galvanized sheet iron press strip.
Above-mentioned elastic helix steel wire coats the location by the glass fiber cloth fixed bed.
Micropore size 1-5 millimeter on the above-mentioned inner protective layer, pitch-row 2-20 millimeter.
The beneficial effects of the utility model: inside and outside protective layer shortens one in port position, seals in the port by the galvanized sheet iron press strip, and flexible pipe port closed cellucotton has solved on-the-spot installation question; External protection is two-sided aluminium foil composite glass fiber cloth, and inner protective layer is the two-sided aluminium foil composite glass fiber of the micropunch cloth that evenly is covered with micropore, and micropore size is little, density is big, has strengthened body noise reduction, sound insulation property, has improved surface strength, prevents to be torn, to puncture.At high temperature can not produce toxic gas, have high flexible, heatproof, corrosion resistant, fire-retardant, insulation, characteristics moistureproof, that easily install, be applicable to various high pressure, middle pressure, low pressure air-conditioning, dust discharge and ventilation system.
