Heat-barrier material is by cap sealed between shell and inner tube;
The joint includes outer metal layer and internal second heat-barrier material, and the outer metal layer bridging is two neighboring anti-
The shell of fire row tracheae section, second heat-barrier material is full of the sky between outer metal layer and two neighboring fire prevention exhaust pipeline section
Chamber.
Further, the block is U-shaped structure, and the wall of U-shaped structure one is connected with outer casing inner wall gluing, sealing, U-shaped structure
Another wall is connected with outer wall of inner tube gluing, sealing;
The wall of U-shaped structure one at outer casing inner wall gluing, sealing with being located in the cavity of outer metal layer sealing, by second
The heat-insulated parcel of heat-barrier material.Because block has been connected inner tube and shell, and block is metal material, can be transferred to partial heat
With the junction of shell, after the heat-insulated parcel of the second heat-barrier material, fire-proof and thermal-insulation effect can be greatly improved.
Further, the wall of U-shaped structure one is bonded with outer casing inner wall is tightly connected by elevated-temperature seal agent.
Further, the connecting plate is L-shaped L-square, and inner pipe end is fixed on the side of L-shaped L-square first, and the second side leads to
Cross the side of L-shaped L-square second that the second bolt is fixedly connected with adjacent fire prevention exhaust pipeline section.
Further, formed with flange, flange is located on the outside of the side of L-shaped L-square second for said inner tube end.L can be ensured
When the side of shape L-square second is by the second bolt connection, connected between inner tube more closely, while connecting plate stress phase can be prevented
Pipeline section is slided, enhances the stability axially connected between pipeline section.
Further, the connecting plate is made with inner tube by stainless steel or Coated Steels.Using the metal system of same type
Into, can avoid between different metal occur couple action possibility.
Further, the shell is the rectangular configuration being spliced by 4 pieces of metallic plates.
The beneficial effects of the utility model are:
1st, pipe design is square-section, can adapt to various ceiling installations in catering trade.
2nd, the structure of heat-barrier material is respectively pressed from both sides inside and outside the use of fire prevention exhaust pipeline section, is used between pipeline section and carries heat-barrier material
Joint sealing, and seal when, the linkage section between block and shell is completely covered in joint, ensure that sealing effect of heat insulation.
The 3rd, flange is set at the connecting plate of two pipeline sections, can ensure to connect more closely between inner tube, while being capable of the company of preventing
Fishplate bar stress is slided with respect to pipeline section, enhances the stability axially connected between pipeline section.
4th, the device can be transported directly to in-site installation, without adding the equipment prepared by other manufacturers again, greatly
Cost has been saved, has saved time and labour.
