Abstract
The invention relates to the technical field of bellow expansion joints, in particular to an unconstrained type expansion joint. The unconstrained type expansion joint comprises a guide tube for media to flow through, a bellow pipe and connection pipes. The outer layer of the guide pipe is sleeved with the bellow pipe, two ends of the guide pipe are provided with the connection pipes, one end of the bellow pipe is connected with the guide pipe through a welded ring, and the other end of the bellow pipe is connected with the guide pipe through a guide ring. According to the unconstrained type expansion joint, the guide ring is utilized for being connected with the guide pipe, when the bellow pipe undergoes the processes of expanding with heat and contracting with cold, the expansion joint can be stretchable, guides freely and is not confined, and therefore use performance of the expansion joint is improved and service life of the expansion joint is prolonged. In addition, the unconstrained type expansion joint has the advantages of being simple in structure, reasonable in design, strong in practicality and the like.
Description
Technical field
The present invention relates to the corrugated expansion joint technical field, be specifically related to without the restricted type expansion joint.
Background technique
The additional stress that expansion joint causes because of temperature difference and mechanical vibration for compensation, and be arranged on a kind of flexible structure on container shell or pipeline.As a kind of elastic compensating element that can free-extension, the advantages such as reliable operation, functional, compact structure have been widely used in the departments such as chemical industry, metallurgy, nuclear energy due to it.Expansion joint also is slip joint traditionally, or corrugated expansion joint, be to utilize effective dilatation of the elastic element of corrugated expansion joint to absorb pipeline, conduit or container by a kind of compensation device of former thereby the dimensional changes that produces such as expand with heat and contract with cold, belong to a kind of compensating element.But bellows expansion joint is in use, and is flexible limited, easily wearing and tearing, and especially under the condition of high temperature, the process of regular experience rising-heat contracting-cold has had a strong impact on working life of expansion joint.
Summary of the invention
The purpose of this invention is to provide a kind of reasonable in design, practical, can stretch voluntarily the guiding without the restricted type expansion joint.
In order to solve the existing problem of background technique, the present invention is by the following technical solutions: without the restricted type expansion joint, comprise honeycomb duct, bellows and the adapter of crossing for MEDIA FLOW, the described bellows of skin socket of described honeycomb duct, the two ends of described honeycomb duct arrange described adapter, one end of described bellows is connected with honeycomb duct by weld-ring, and the other end of described bellows is connected with honeycomb duct by guide ring.
Further, the skin of described bellows is provided with oversheath.
Further, described bellows is metal bellows.
The present invention has following beneficial effect: of the present invention without the restricted type expansion joint, comprise honeycomb duct, bellows and the adapter of crossing for MEDIA FLOW, wherein, adopt guide ring that bellows is connected with honeycomb duct, retractable guiding in the process of bellows experience rising-heat contracting-cold, unrestricted, thus the usability of expansion joint improved, extended the working life of expansion joint.In addition, the present invention has the characteristics such as simple in structure, reasonable in design, practical.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The present invention will be further described in detail below in conjunction with accompanying drawing.
as shown in Figure 1, without the restricted type expansion joint, comprise the honeycomb duct 1 of crossing for MEDIA FLOW, bellows 2 and take over 3, the described bellows 2 of skin socket of described honeycomb duct 1, the two ends of described honeycomb duct 1 arrange described adapter 3, one end of described bellows 2 is connected with honeycomb duct 1 by weld-ring 4, by weld-ring, bellows is fixedly connected with honeycomb duct, the other end of described bellows 2 is connected with honeycomb duct 1 by guide ring 5, guide ring connects bellows and honeycomb duct, in the process of expansion joint experience rising-heat contracting-cold, drive bellows retractable guiding by guide ring, thereby raising functional reliability, increase the service life.
The skin of described bellows 2 is provided with oversheath 6, adopts the purpose of oversheath to be bellows is played safety, protective action.
Described bellows 2 is metal bellows, because metal bellows has the characteristics such as corrosion-resistant, anti-aging, leakage proof, thereby can extend the working life of expansion joint.
Explanation is at last, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, other modifications that those of ordinary skills make technological scheme of the present invention or be equal to replacement, only otherwise break away from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of claim scope of the present invention.
Claims (3)
1. without the restricted type expansion joint, comprise honeycomb duct (1), the bellows (2) of crossing for MEDIA FLOW and take over (3), it is characterized in that, the skin socket described bellows (2) of described honeycomb duct (1), the two ends of described honeycomb duct (1) arrange described adapter (3), one end of described bellows (2) is connected with honeycomb duct (1) by weld-ring (4), and the other end of described bellows (2) is connected with honeycomb duct (1) by guide ring (5).
2. according to claim 1ly it is characterized in that without the restricted type expansion joint, the skin of described bellows (2) is provided with oversheath (6).
