Description
Technical Field
The utility model relates to a waste gas treatment technical field, concretely relates to sealed butt joint structure of tuber pipe between module among modularization waste gas treatment device.
Background
The air pipe sealing butt joint structure is an important part for realizing air pipe butt joint between modules in the modular waste gas treatment device. The air pipe sealing butt joint structure is small in gap when butt joint between the modules can be achieved, the butt joint condition of the air pipes cannot be seen, and operation of butt joint of the air pipes between the modules is achieved under the condition that hands and tools do not have operation spaces.
At present, the butt joint of the air pipes mainly adopts the following forms:
the glue joint can not be repeatedly disassembled, and the glue joint needs destructive disassembly when being disassembled;
socket butt joint requires very high precision, when the butt joint condition is invisible, the butt joint is difficult, equipment processing precision is also required to be high, and equipment processing cost is increased;
mechanical butt joint can adopt methods such as flange butt joint between air pipes, riveting between the air pipes, use of a special butt joint buckle structure and the like, but the butt joint needs an operation space and can be carried out only under the condition that the butt joint is visible;
welding butt joint also requires an operating space, and when the welding butt joint is disassembled, destructive disassembly is required.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at providing a sealed butt joint structure of tuber pipe to when realizing the visual butt joint of tuber pipe between the module, improve the reliability and the convenience of tuber pipe butt joint.
The utility model discloses an above-mentioned problem is solved to following technical means: the utility model provides a sealed butt joint structure of tuber pipe, includes tuber pipe A and tuber pipe B, the fixed cup joint of butt joint end of tuber pipe A has cyclic annular seal groove, tuber pipe B's butt joint end is pegged graft with the seal groove, the seal groove intussuseption is filled with the jelly that is used for realizing that tuber pipe B's butt joint end cup joints with the seal groove is sealed.
Furthermore, the inner diameter of the air pipe B is larger than that of the sealing groove, and the outer diameter of the air pipe B is smaller than that of the sealing groove.
Further, the cross-section of seal groove is the U style of calligraphy.
Further, the height of the inner side wall of the sealing groove is larger than that of the outer side wall.
Furthermore, the end face of the butt joint end of the air pipe A exceeds the sealing groove.
The utility model has the advantages that: the utility model provides a sealed butt joint structure of tuber pipe, including tuber pipe A and tuber pipe B, the fixed cup joint of butt joint end of tuber pipe A has cyclic annular seal groove, tuber pipe B's butt joint end is pegged graft with the seal groove, the seal groove intussuseption is filled with the jelly that is used for realizing that tuber pipe B's butt joint end and seal groove seal cup joint. Adopt the sealed butt joint structure of tuber pipe of this application, when realizing the visual butt joint of tuber pipe between the module, improve the reliability and the convenience of tuber pipe butt joint.
Drawings
The invention is further described with reference to the following figures and examples.
FIG. 1 is a schematic view of the assembly of the present invention;
fig. 2 is an exploded view of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. The features and advantages of the present invention will become more apparent from the description. It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them.
As shown in fig. 1-2, the air duct sealing and docking structure of the present embodiment includes an air duct a1 and an air duct B2. The fixed cyclic annular seal groove 3 that has cup jointed of tuber pipe A1, the cross-section of seal groove 3 is the U style of calligraphy, and the inside wall height of seal groove 3 is greater than the lateral wall height. The butt joint end and the seal groove 3 of tuber pipe B2 are pegged graft, the packing is filled with jelly glue 4 in the seal groove 3, and the liquid level height of jelly glue 4 is not higher than the lateral wall of seal groove, can realize that the sealed of tuber pipe B and seal groove cup joints after the jelly glue solidifies.
Preferably, the inner diameter of the air pipe B2 is larger than that of the sealing groove 3, and the outer diameter of the air pipe B2 is smaller than that of the sealing groove 3. By adopting the structure design, in the plugging process, a gap exists between the butt joint end of the air pipe B2 and the sealing groove 3, so that smooth plugging under the invisible condition is facilitated.
Preferably, the end face of the butt end of the air pipe a1 exceeds the sealing groove 3. By adopting the structure design, after the air pipe A1 is in butt joint with the air pipe B2, the butt joint end of the air pipe A1 and the butt joint end of the air pipe B2 can be overlapped and sleeved, so that the butt joint precision can be improved.
The jelly glue 4 can be replaced by any other glue without viscosity but with good elastic deformation;
the air pipe can be in any shape;
the air pipe butt joint installation mode can be horizontal butt joint or vertical butt joint, and is suitable for air pipe butt joint at any angle;
the larger the distance between the outer diameter and the inner diameter of the sealing groove is, the easier the air pipe butt joint work is, and the easier the invisible fool operation is realized.
In conclusion, adopt the sealed butt joint structure of tuber pipe of this application, when realizing that the tuber pipe is visual butt joint between the module, improve the reliability and the convenience of tuber pipe butt joint.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
