Abstract
The utility model relates to a spigot-and-socket non-flange blast pipe joint made of glass fiber reinforced plastic. A left blast pipe is provided with a staircase-shaped reducing pillow block; a right blast pipe is provided with a concave hole corresponding to the pillow block; rubber strips are arranged between the end surface of the top of the pillow block and the end surface of the bottom of the concave hole; the splicing part of the pillow block and the concave hole is riveted and fastened by a plurality of radial drawing rivets; fillings made of inorganic glass fibre reinforced plastic material are filled into a gap between the end surface of the top of the concave hole and the end surface of the bottom of the pillow block. The utility model has the functions of fire prevention, flame resistance and thermal insulation and has the advantages of good joint tightness, convenient installation and low cost.
Description
The utility model relates to central air-conditioner and the inorganic glass fibre reinforced plastics ventilation pipeline linkage structure of the usefulness of taking out, discharge fume, and specifically a kind of spigot and socket type can't blue glass fibre reinforced plastic blast pipe interface.
Inorganic glass fibre reinforced plastic blast pipe has characteristics such as body is light, intensity is high, corrosion-resistant, at central air-conditioner and take out, be used widely in the smokejack.The linkage structure of existing inorganic glass fibre reinforced plastic blast pipe is to use the affixed flange plate of pipe end to be connected and fixed with bolt, this linkage structure exist install that labor intensity is big, the joint outstanding, not attractive in appearance, because of the flange plate height that the 50-70 millimeter is arranged influences ceiling height.
Existing insulation shape airduct has PVC plug-in unit newly developed to connect, this Placement because of do not prevent fires, the temperature tolerance difference must not be used in and take out, the engineering of discharging fume, its outward appearance joint is obvious, will just can reach requirement through careful encapsulation process during installation, because of the use pair of a large amount of PVC plastics adds the cost height.Prior art has improves perfect necessity, increases new kind.
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of spigot and socket type can't blue glass fibre reinforced plastic blast pipe interface, and it has fire prevention, fire-retardant, thermal insulation property, and the jointing good seal performance is easy for installation, and cost is the end of than, and Applicable scope is extensive.
The purpose of this utility model is achieved in that
A kind of spigot and socket type can't blue glass fibre reinforced plastic blast pipe interface, and it comprises the left and right airduct of the hollow of FRIM material, it is characterized in that:
Left side airduct has the pillow block of stepped undergauge, right airduct has and the corresponding shrinkage pool of pillow block, this pillow block is plugged in this shrinkage pool, between pillow block top end face and shrinkage pool bottom end face, adhesive tape is housed, fastening in the grafting of pillow block and shrinkage pool part with some pulling rivets riveted joints radially, be filled with the packing of FRIM material in the slit between the top end face of the bottom end face of pillow block and shrinkage pool.
The purpose of this utility model can also realize by following measure:
Described FRIM is a magnesia oxychloride cement glass fibre reinforced plastics; Described adhesive tape is 8501 sealing joint strips.
Described have the end in addition of the left airduct of pillow block that shrinkage pool is arranged, and has the end in addition of the right airduct of shrinkage pool that pillow block is arranged.
The cross section of described airduct can be rectangular, also can be rounded, the shape of cross section of described pillow block, shrinkage pool also corresponding rectangular/circle.
The utility model has following actively useful effect:
Existing inorganic glass fibre reinforced plastics ventilation pipeline linkage structure is compared, this product joint seamlessly transits, does not have sharp trace, integrated molding does not use outer the overlay to help material, material own has performances such as fire prevention, fire-retardant, insulation, the jointing good airproof performance, easy for installation, laborsaving, save time, because of the reduction of cost of production helps the promotion of inorganic glass fibre reinforced plastic blast pipe on market.
This product mainly is used in the ventilating engineering duct collar, includes the place of insulation requirement and non-insulation.
Now in conjunction with the accompanying drawings:
Fig. 1 is the utility model one embodiment's a structural representation.
