Abstract
A novel non-metallic expansion joint relates to a non-metallic expansion joint, which consists of a connecting pipe (1), an ear plate (2), a flexible astragal (3), a screw nut (4), a screw stud (5), high-alumina fiber cotton (6), a honeycomb duct (7) and, an internal honeycomb duct (8) and a hinge (9); the connecting pipe (1) is arranged at the bottom end of the ear plate (2), and both are connected in vertical manner; high-alumina fiber cotton (6) is arranged underneath the flexible astragal (3), the hinge (9) is arranged above the high-alumina fiber cotton (6), the screw stud (5) is arranged on one side of the screw nut (4), and the honeycomb duct (7) is arranged underneath the internal honeycomb duct (8); the surface layer of the hinge (9) is made of stainless steel mesh, and the internal layer thereof consists of silicone rubber cloth, intensified fabric cloth, tetrafluoro cloth, glass fiber cloth and alkali free cloth, has excellent flexibility, has reverse thrust influence on the equipment and the system, is convenient to the pipeline design, and can control satisfactorily the length prolonged of the expansion joint, therefore the expansion joint is not likely to be damaged.
Description
Technical field:
The utility model relates to a kind of non-metal expansion joint.
Background technique:
Non-metal expansion joint also claims non-metal compensator, fabric compensator, belongs to a kind of of compensator.Its material be mainly fabric, rubber, etc. exotic material.The vibrations and the pipe deforming of energy air blower of compensating, airduct operation.But non-metal expansion joint compensating axial, horizontal, angle, have no thrust, simplify susceptor design, characteristics such as corrosion-resistant, high temperature resistant, noise elimination vibration damping, be specially adapted to hot air duct and fume ducts, but have since flexibility be not fine, equipment and system there is not too big reaction thrust influence, length that also cannot its elongation of better controlled is easy to damage.
The model utility content:
The purpose of this utility model provides a kind of new nonmetal expansion joint, it has good flexibility, equipment and system there is the reaction thrust influence, bring convenience to piping design, also improved the Security of equipment and system, absorb displacement in the unit length and become big. the three-dimensional displacement amount can be absorbed, 40% of effective length can be reached; Install simply, change easily, adaptability is strong, can be made into arbitrary shape and any girth; Vibration isolating effect is good, is bordering on zero vibration transfer; High temperature resistant reaching more than 1000 degree; Corrosion-resistant, but sound-insulating and heat-insulating, have low noise can characteristics.In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it is made up of adapter 1, otic placode 2, soft ring band 3, nut 4, double-screw bolt 5, high alumina pricker vinylon and cotton blend 6, honeycomb duct 7, interior honeycomb duct 8 and hinge 9; Take over 1 bottom that is arranged on otic placode 2, and the two is connected vertically, the below of soft ring band 3 is provided with high alumina pricker vinylon and cotton blend 6, and high alumina pricker vinylon and cotton blend 6 is provided with hinge 9, and double-screw bolt 5 is arranged on a side of nut 4, the below of honeycomb duct 8 in honeycomb duct 7 is arranged on.
The top layer that described hinge 9 is is to be made of the stainless steel steel wire, nexine is made up of as adhesive plaster, cloth of reinforcement fibers, tetrafluoro cloth, glass fiber cloth, compound day alkali cloth silicon, good flexibility is arranged, to the outstanding reaction thrust shadow of equipment and system, bring convenience to piping design, can well control the length of its elongation, be not easy to damage.
The utlity model has following beneficial effect: good flexibility is arranged, to the outstanding reaction thrust shadow of equipment and system, brought convenience to piping design, also improved the Security of equipment and system, absorb displacement in the unit length and become big. the three-dimensional displacement amount can be absorbed, 40% of effective length can be reached; Install simply, change easily, adaptability is strong, can be made into arbitrary shape and any girth; Vibration isolating effect is good, is bordering on zero vibration transfer; High temperature resistant reaching more than 1000 degree; Corrosion-resistant, but sound-insulating and heat-insulating, have low noise can characteristics.
Description of drawings:
Fig. 1 is this practical structural representation.
Embodiment:
This embodiment is by the following technical solutions: it by take over 1, otic placode 2, soft ring band 3, nut 4, double-screw bolt 5, high alumina pricker vinylon and cotton blend 6, honeycomb duct 7, interior honeycomb duct 8 and hinge 9 form; Take over 1 bottom that is arranged on otic placode 2, and the two is connected vertically, the below of soft ring band 3 is provided with high alumina pricker vinylon and cotton blend 6, and high alumina pricker vinylon and cotton blend 6 is provided with hinge 9, and double-screw bolt 5 is arranged on a side of nut 4, the below of honeycomb duct 8 in honeycomb duct 7 is arranged on; The top layer that hinge 9 is is to be made of the stainless steel steel wire, nexine is made up of as adhesive plaster, cloth of reinforcement fibers, tetrafluoro cloth, glass fiber cloth, compound day alkali cloth silicon, good flexibility is arranged, equipment and system there is the reaction thrust influence, brought convenience to piping design, can well control the length of its elongation, be not easy to damage, absorb displacement in the unit length and become big. the three-dimensional displacement amount can be absorbed, 40% of effective length can be reached; Install simply, change easily, adaptability is strong, can be made into arbitrary shape and any girth; Vibration isolating effect is good, is bordering on zero vibration transfer; High temperature resistant reaching more than 1000 degree; Corrosion-resistant, but sound-insulating and heat-insulating, have low noise can characteristics.
