Abstract
The utility model discloses a flexible joint used for fluid pipe connection. A hose is formed through an inner bond layer (3), an outer bond layer (4) and an enhancement layer arranged between the inner body layer (3) and the outer bond layer (4), wherein support steel rings (2) are arranged at both ends of the hose; and the inner bond layer (3) protrudes out of the outer end surface of each support steel ring (2) and forms a circle of sealing lip edge (1) on each support steel ring (2). The flexible joint solves the compensation problem in pipeline manufacture and installation error as well as the problems of vibration compensation and thermal expansion and contraction compensation of pipelines, has more compact structure, stronger compensation capability and more reliable seal compared with other flexible connection devices; when in connection, the flexible joint is unrelated to the adopted flange standard of the pipeline, thereby solving the standard converting problem when flanges of different standards are connected together; and through adopting the flexible joint, standardization can be realized easily, and compatibility with the conventional various flange standards is available after the standardization.
Description
Technical field
The utility model relates to the flexible joint that a kind of fluid line connects usefulness, and particularly a kind of latus rectum connects the flexible joint of usefulness greater than 15mm fluid line flange.Be used to compensate the pipeline manufacturing and generation static error, compensation be installed owing to the line size that vibrate, expand with heat and contract with cold, stressed etc. produces changes.Eliminate because the stress that error and dimensional changes produce prevents because device damage, seal failure, generation vibration and the noise that pipe stress causes.
Background technique
At present, in the pipeline of FLUID TRANSPORTATION and fluid transmission connected, it was essential to flexibly connect.Flexibly connect as adopting, be used to protect the not fragile purpose that reaches vibration and noise reducing simultaneously of pump in the import and export of pump.
Present big latus rectum flanged pipe flexible connecting method is employed in pagoda head of welding on the flange more, sebific duct is fixed on the pagoda head with pipe collar again.This method has two defectives: it is unreliable one, to connect, and phenomenons such as sebific duct comes off, poor sealing often take place; Two, limit by the compensation ability and the bending radius allowable of straight-through sebific duct, must have enough big space to arrange sebific duct, can not use in the place of limited space.Therefore in the compact place of most of claimed structures, have to adopt the way that customizes curved sebific duct to solve the restriction of sebific duct bending radius allowable, occurred a new problem so again, every kind of curved sebific duct of customization only adapts to some certain location.Even the place that receives serious restriction in some spaces is had to abandon flexibly connecting and is adopted the mode of joining weldering.
Simultaneously the present flange that adopts has several standards, and not general mutually, even the element interface flange that has uses is the inside plants standard.Therefore the switching between the various various criterion flanges is a headachy problem always in engineering practice.
The model utility content
The utility model technical problem to be solved provides a kind of flexible joint that reliable, good seal performance, fluid line that compensation ability is strong connect usefulness that connects.
In order to solve the problems of the technologies described above; The fluid line that the utility model provides connects the flexible joint of usefulness; Inner glue layer and outside be provided with one deck enhancement layer between the glue-line and form flexible pipe; The two ends of described flexible pipe are equipped with the support steel ring, and projection is formed with a circle sealing lip limit to described inner glue layer in the exterior edge face of described support steel ring.
Further, being formed with cydariform in the middle part of the described flexible pipe expands.
Further, the endoporus of described support steel ring is the stepped shaft through hole, and described inner glue layer and described enhancement layer left-hand thread are in the endoporus bead of described support steel ring.
Further, the flexible pipe of being made up of described inner glue layer, enhancement layer and outer glue-line and the described support steel ring integral body at two ends sulfide.
More than improving technological scheme can implement alone or in combination.
Adopt the flexible joint of the fluid line connection usefulness of technique scheme, comprise the flexible pipe that is made up of inner glue layer, enhancement layer, outer glue-line, this flexible pipe provides radially, axial and angular compensatory ability; The support steel ring at flexible pipe two ends; Supporting steel ring and flexible pipe sulfides.Inner glue layer seals on support steel ring exterior edge face projection formation one circle sealing lip limit; The flexible pipe middle part that inner glue layer, enhancement layer, outer glue-line are formed jointly has a cydariform to expand, and this cydariform expands to be provided radially better, axial and angular compensatory ability; Inner glue layer provides the fluid compatibility ability; Enhancement layer provides withstand voltage properties; Outer glue-line provides weather-proof wear-resisting property.The utility model adopts the subdivision flange to be pressed in the support steel ring at two ends on the piping flange that is attached thereto in use or on the flange of element, supports steel ring and can bear bigger impacting force, and the sealing lip limit provides reliable sealing.Therefore the utlity model has and connect that reliable, good seal performance, compensation ability are strong, the characteristics of compact structure.
Though find that in engineering practice the flange of various standards is not general mutually; But the latus rectum classification that various standard adopted but be one to or approaching; The flange standard that adopts with pipeline when simultaneously the utility model connects has nothing to do; Therefore so long as same latus rectum just can be connected with the flange of various criterion, solved the standard handovers problem that the flange of various criterion links together.Therefore the utlity model has can be compatible with existing most of standard flange, be easy to realize standardized characteristics.
In sum, the utility model has solved the compensation problem of pipeline manufacturing alignment error; The utility model has solved the pipe vibration compensation and the compensation problem of expanding with heat and contract with cold; The utility model is compact more with respect to other flexible connecting structure, compensation ability is stronger, sealing is more reliable; The flange standard that adopts with pipeline when the utility model connects has nothing to do, and has solved the standard handovers problem that the flange of various criterion links together; The utility model is easy to realize standardization, and after the standardization can also with existing various flange operating suchs.The utility model be a kind ofly connect that reliable, good seal performance, compensation ability are strong, compact structure, can be compatible with existing most of standard flange, be easy to realize that standardized fluid line is connected the flexible joint of usefulness.
