Abstract
The invention provides a nonmetallic expansion joint which comprises a skin and a framework from the inside to the outside. The skin is fixed onto the framework by the aid of screws and nuts, the framework is made of channel steel, the skin comprises silicone rubber coated glass fiber cloth layers, polytetrafluoroethylene film layers, alkali-free glass fiber cloth layers, other polytetrafluoroethylene film layers and polytetrafluoroethylene coated glass fiber cloth layers from the outside to the inside, and the various layers are adhered with one another by binders. The nonmetallic expansion joint has the technical advantages of difficulty in abrasion and long service life.
Description
Technical field
The present invention relates to a kind of non-metal expansion joint, belong to field of mechanical technique.
Background technology
Expansion joint is for compensating the additional stress because temperature difference and mechanical vibration cause, and is arranged on a kind of flexible structure on container casing or pipeline.Owing to it is as a kind of elastic compensation element that can freely stretch, there is the advantage such as reliable operation, functional, compact conformation, have been widely used in departments such as chemical industry, metallurgy, nuclear energy.Including type metal expansion joint and non-metal expansion joint.Wherein non-metal expansion joint includes following two:
1) rubber air channel expansion joint
Air duct rubber compensator is divided into tetra-kinds of models of FDZ, FVB, FUB, XB; it is made up of rubber and rubber one fabric composite, steel flanges, sleeve, heat preserving and insulating material; it is mainly used in flexibly connecting between various blower fan, airduct; its function is damping, noise reduction, sealing, media-resistant, is easy to displacement and installation, is the best auxiliary equipment of a kind of highly desirable damping, noise reduction, smoke abatement and dust control in field of environment protection.
2) fabric expansion joint
Fabric compensator be mainly fabric, rubber, etc. exotic material.Can air blower of compensating, airduct run vibrations and pipe deforming.Fabric expansion joint can compensate for the products such as axial, horizontal, angular, has without thrust, simplifies the feature such as susceptor design, corrosion-resistant, high temperature resistant, silencing vibration-damping, is particularly well-suited to power plant's hot air duct and fume ducts.Fabric in non-metal compensator, heat-preservation cotton body itself have the function of sound absorption, vibration isolation, can effectively reduce noise and the vibration of the system such as boiler, blower fan.Simple in construction, body are light, easy to maintenance.
Existing non-metal expansion joint is primarily present the weak point using easily abrasion, life-span shorter.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art part, it is provided that a kind of non-metal expansion joint.
The non-metal expansion joint of the present invention, include eyelid covering and frame from inside to outside, described eyelid covering is fixed in frame by screw and nut, and described frame adopts channel-section steel to be raw material, described eyelid covering include from outside to inside following which floor: 1) Silicone Rubber Coated fiberglass cloth；2) polytetrafluoroethylene film layer；3) alkali-free glass fiber cloth layer；4) polytetrafluoroethylene film layer；5) politef coated glass fiber layer of cloth, described each layer forms by binding agent is bonding.
Preferably,
Stainless steel cloth, heat-insulation layer and thermal insulating filling layer it is additionally provided with between described eyelid covering and frame.
Described heat-insulation layer includes glass fabric, high silica cloth and heat-preservation cotton felt.
Described thermal insulating filling layer includes multi-layer ceramics fiber.
The non-metal expansion joint of the present invention has and is not easy abrasion, uses time longer technique effect.
