Description
Technical field
The utility model is related to field of pipeline equipment, specially a kind of fire-retardant bellows of high tenacity.
Background technology
Bellows is widely used among our life, and species is various, is mainly expanded including metal bellows, ripple
Section, corrugated tube, diaphragm and diaphragm capsule and metal hose etc., metal bellows are mainly used in compensation pipes thermal deformation, damping, suction
Closed tube line sedimentation and deformation etc. is acted on, and is widely used in the industries such as petrochemical industry, instrument, space flight, chemical industry, electric power, cement, metallurgy, plastics
Play the role of etc. other materials bellows in the field such as medium conveying, electric power threading, lathe, household electrical appliances it is irreplaceable, at present with
The requirement more and more higher of people, it is also increasingly stricter to the performance requirement of bellows, therefore design a kind of for problem above
The fire-retardant bellows of high tenacity.
Utility model content
For problem above, the utility model provides a kind of fire-retardant bellows of high tenacity, and global design can have very
Good fire resistance is with stronger toughness, the problem of effectively can solving in background technology.
To achieve the above object, the utility model provides following technical scheme：A kind of fire-retardant bellows of high tenacity, including pipe
Body, the tube wall is raised provided with several, the raised ripple in a ring, and the tube wall is provided with flame-retardant layer, described
It is filled with flame-retardant layer between fire-retardant particle, the adjacent protrusion and is provided with connecting spring, link is passed through between the connecting spring
It is connected.
As a kind of preferred technical scheme of the utility model, the inboard wall of tube body is provided with steel screen layer.
As a kind of preferred technical scheme of the utility model, the flame-retardant layer outer surface is provided with metal cladding.
As a kind of preferred technical scheme of the utility model, the link is provided with breach.
Compared with prior art, the beneficial effects of the utility model are：The utility model is by tube wall provided with fire-retardant
Layer, reaches fire-retardant effect by the fire-retardant particle filled in flame-retardant layer, is provided with addition between the adjacent protrusion of tube wall
Connecting spring, connecting spring is connected with each other by link, can be dismantled, and passes through the elastic force and restoring force of connecting spring, energy
Whole body is possessed very strong toughness, thus the utility model global design can have good fire resistance with it is stronger
Toughness, global design is simple in construction, with more wide market prospects, is easy to promote.

Pipe, including body 1, the outer wall of body 1 is provided with several projections 2, and described raised 2 ripples in a ring, the outer wall of body 1 is set
Have to be filled between fire-retardant particle 4, the adjacent protrusion 2 in flame-retardant layer 3, the flame-retardant layer 3 and be provided with connecting spring 5, the company
Connect and be connected by link 6 between spring 5；The inwall of body 1 is provided with steel screen layer 7；The outer surface of flame-retardant layer 3 is provided with plating
Metal level 8, plays anticorrosion ability, and protection is played a part of to body；The link 6 is provided with breach 9, easy to disassemble.
The utility model is provided with flame-retardant layer 3 by the outer wall of body 1, and resistance is reached by the fire-retardant particle 4 of filling in flame-retardant layer 3
The effect of combustion, is provided with connecting spring 5 between the adjacent protrusion 2 of the outer wall of body 1 in addition, and connecting spring 5 is mutually interconnected by link 6
Connect, can be dismantled, by the elastic force and restoring force of connecting spring 5, whole body 1 can be made to possess very strong toughness.
Based on above-mentioned, the utility model has the advantage that：The utility model global design can have resistance well
Performance and stronger toughness are fired, global design is simple in construction, with more wide market prospects, be easy to promote.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modifications, equivalent substitutions and improvements made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
