Abstract
The utility model discloses a flexible high-temperature-resisting manhole. A manhole which is formed in equipment is fixedly connected with one end of an equipment connecting pipe, a thermal insulating layer is laid on the manhole, the periphery of the other end of the equipment connecting pipe is fixedly connected with one end of a flexible connecting pipe, and protrusions are arranged on the periphery of a connecting portion of the equipment connecting pipe and the flexible connecting pipe. A flange is arranged at the other end of the flexible connecting pipe, a concave-convex groove and a corresponding connecting hole are correspondingly formed in a contact face of the flange and a cover plate, the concave-convex groove is connected with the connecting hole by a fastener, and gaskets are arranged on a connecting portion of the fastener and the flange, and a connecting portion of the fastener and the cover plate. The flexible connecting pipe, the flange and the cover plate are made of heat-resisting rubber or high-temperature-resisting plastics. The capacity of deformation absorption of flexible materials is utilized to remove stress concentration produced in structures such as a manhole connecting pipe, the flange and seal due to high temperature deformation, and accordingly strength damage and seal failure of a manhole structure under high temperature are avoided. Heat-resisting, heat-insulating and corrosion-resisting performance of the flexible materials is utilized, so that design is simplified, and manufacturing cost is saved.
Description
Technical field
The utility model relates to a kind of for the manhole device on the worst hot case equipment, is specially the high temperature resistant manhole of a kind of flexibility.
Background technology
At the equipment that works in worst hot case manhole is set, its design and type selecting are different from the equipment manhole that works under the lower temperature operating mode, the latter can consider too much that temperature to the adverse effect that manhole rigidity, sealing etc. cause, then is topmost influence factor for the former temperature.In order to adapt to worst hot case, the measure that manhole is often taked in structure design and material selection:
The one, utilize refractory metal material to make manhole.Though this manhole can tolerate worst hot case, but it to insulation and the requirement of structure design than higher, yet manhole often structure is simpler, be the shaped piece that equipment is convex in shape, layout in addition, so in fact often out of reach designing requirement of the serviceability of manhole, easily lost efficacy as sealing property, under malleation operating mode and splendid attire hazardous medium situation, this problem performance is particularly outstanding.Be to solve the illusive problem of sealing, adopt manhole plate directly to be welded on way on the manhole at structure design, but this allows unlatching, the closure of manhole become thorny again.In addition, the refractory metal material cost is often higher, increases the manufacturing cost of manhole, does not meet the requirement of economy.
The 2nd, high temperature resistant manhole is to take to build/lay thermal insulating material by laying bricks or stones in manhole inside on engineering, and isolated manhole metal part contacts with high-temperature medium.This method is constructed easily, easy to use, it is firm that but heat preserving and insulating material often is difficult to attach, especially for a long time work under the high temperature and equipment frequently heats up, lowering the temperature adds unloading and cause because metal partly is out of shape etc. thermal insulating material is come off, cause seal failure, in addition, the thickness of thermal insulating material is generally bigger, taken the space of manhole and equipment preciousness, these all are the shortcomings of this manhole.
Summary of the invention
At the problems referred to above, the purpose of this utility model is, a kind of manhole is provided, can satisfy resistant to elevated temperatures basic demand, solve the problem of the function inefficacy (sealing property etc.) that heat-resisting, adiabatic (insulation) and the high temperature deformation of manhole cause, have the characteristics of easy implementation, simple in structure, easy care, economy again concurrently.
For achieving the above object, the utility model is taked following technical scheme, the high temperature resistant manhole of a kind of flexibility, comprise flexible connecting pipe, flange and cover plate, it is characterized in that, the end that the manhole place captive joint equipment of offering on the equipment is taken over also is laid with heat-insulation layer, the other end periphery that equipment is taken over is fixedly connected with an end of flexible connecting pipe, equipment is taken over flexible connecting pipe junction periphery and is provided with protrusion, the other end of flexible connecting pipe is provided with flange, flange is connected fastener and flange with the corresponding concavo-convex groove that is provided with of contact surface of cover plate with corresponding connecting bore and by fastener, the cover plate junction is lined with pad.
Described flexible connecting pipe, described flange and described cover plate materials are heat enduring rubber or high-temperature resistance plastice.
Described protrusion is bitch or projection or raised line.
The combination that is shaped as " Y " shape, " I " shape, "+" shape, "T"-shaped or above shape of described bitch.
Advantage of the present utility model is to utilize flexible material to absorb deformation ability elimination high temperature deformation and concentrates at the stress that structures such as manhole adapter, flange, sealing produce, thereby the intensity of avoiding the manhole structure to take place under the high temperature is broken ring and seal failure, the utility model has taken full advantage of heat-resisting, heat insulation, the antiseptic property of flexible material self simultaneously, has simplified design, has saved manufacturing cost; Because flexible material is easy to processing, has shortened the manufacturing cycle; The bolt with flange form is adopted in the keying of manhole, has made things convenient for user's daily operation and maintenance; The pressure ring of two rigidity has guaranteed that the sealing of faying face between flange, the cover plate is reliable; The design of bitch has strengthened flexible connecting pipe and equipment is taken over gluing connect firm.
