The utility model has light weight, novel structure and very convenient use, and can realize fast connection at the construction site, thereby saving the labor; the seal intensity of the tray expansion bend can be adjusted within the wide range, thereby achieving the safer and more reliable sealing; moreover, the utility model has high expansion compensation rate, thereby particularly suiting plastic tubes with high thermal expansion coefficients and rigid coupling pipelines with large stress.
Description
Technical field
The utility model belongs to pipeline connection device technical field, has been specifically related to a kind of tray expansion bend.
Background technique
In the pipeline construction of conglomerate, in pipe-line systems such as water supply and drainage, housing estate development, oil, sewage, rock gas, electric power, often need expansion bend that plastic tube, cast iron tube, nodular cast iron pipe or steel pipe are connected.But traditional expansion bend must just can be attached thereto by means of flange plate, flange short tube and relevant pipe fitting because its structural limitations can not directly be inserted pipe (promptly can not directly link to each other with pipe).Therefore using traditional expansion bend that new pipeline is installed or when original pipeline keeped in repair, needing field welding, or on-the-spotly beating mouth, and need could be connected with pipeline by the transition of other pipe fitting, promptly consumptive material is time-consuming again.And traditional expansion bend the regulated quantity to sealing intensity is very little at the construction field (site) so that often the leakage accident takes place, poor stability.
The model utility content
The purpose of this utility model just is to overcome the deficiencies in the prior art part, and a kind of simple installation, the reliable tray expansion bend of sealingly secure are provided.
For achieving the above object, the technological scheme taked of the utility model is as follows:
A kind of tray expansion bend, comprise the expansion bend body, expansion bend body one end is the flange plate that has bolt hole, the other end is a bellmouth, its improvements are: be provided with seal ring on the bellmouth inwall of expansion bend body, the bellmouth end inwardly is provided with the turning end plate, is provided with the adjusting pressure ring between turning end plate and the seal ring, circumferentially uniformly on the end plate of turning is equipped with at least two and regulates bolts hole.
Further, regulate in the bolt hole and be equipped with the adjusting bolt, regulate bolt and regulate pressure ring to the adjusting of seal ring enforcement sealing intensity by compressing.
Preferably, seal ring is preferably the inclined-plane with the surface of contact of regulating pressure ring, thus when regulating pressure ring transfer function power, active force can be simultaneously to radially (pipe direction)) exert pressure with axially (seal ring direction), obtain sealing effect preferably between pipe and the seal ring.
Seal ring is a rubber seal, belongs to flexible sealing, and sealing intensity can be in very large range adjusted.
The flange plate end plane is provided with the flange rubber cushion, is used for flange on flange plate one end and the pipeline or the sealing between the valve pipe fitting flange.
Advantage of the present utility model:
1, compare with traditional expansion bend, the utility model is in light weight, novel structure.
2, the utility model is very easy to use, no matter be new pipe laying or original pipeline keeped in repair all do not need field welding, do not need to beat mouth yet, can directly be connected with pipeline, save manpower and other pipe fitting, when carrying out the piping erection construction, only need flange plate one end of the utility model tray expansion bend is linked to each other with the flange of equipment in the pipeline, the other end directly inserts pipe in the bellmouth and gets final product.
3, the utility model carries the flange rubber cushion because of flange plate, and bellmouth also carries seal ring, can realize that the job site connects fast.
4, seal ring of the present utility model is rubber flexible sealing, by tightening the adjusting bolt, by regulating the pressure ring power transmission in seal ring, makes that sealing intensity can in very large range can be adjusted, seals more safe and reliable.
5, the utility model flexible compensation amount is big, is specially adapted to the bigger plastic tube of thermal expansion coefficient and produces the bigger rigid line of stress.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is done into a ground and introduce in detail, but protection domain of the present utility model is not limited thereto:
As shown in drawings, a kind of tray expansion bend, comprise expansion bend body 1, expansion bend body 1 one ends are the flange plate 11 that has bolt hole 111, flange plate 11 end planes are provided with flange rubber cushion 5, expansion bend body 1 the other end is a bellmouth 12, bellmouth 12 inwalls are provided with seal ring 2, bellmouth 12 ends bend inwards and are provided with turning end plate 121, be provided with between turning end plate 121 and the seal ring 2 and regulate pressure ring 3, seal ring 2 is the inclined-plane with the surface of contact of regulating pressure ring 3, circumferentially is laid with eight on the turning end plate 121 and regulates bolt hole, regulates interior corresponding being equipped with of bolt hole and regulates bolt 4.
During use, at first transfer the adjusting bolt 4 in the adjusting bolt hole on the loose turning end plate 121, make its seal rings 2 that are in relaxed state and the bellmouth 12 be in the state of not being squeezed, flange plate 11 1 ends are linked to each other with flange or valve pipe fitting flange seal on the pipeline by bolt hole 111 and flange rubber cushion 5, it is interior (when pipe 6 inserts that pipe 6 is inserted bellmouth 12, can on pipe 6, smear soap solution in advance to reduce friction convenient the insertion; Insert the total length that length should be slightly less than expansion bend body 1, can draw in advance in the insertion end of pipe 6 and prepare to insert the length graticule) so that accurately hold, after pipe 6 inserts, circulation is tightened and is regulated bolt 4 and exert pressure to regulating pressure ring 3 gradually, thus, regulate pressure ring 3 simultaneously to power transmission radially in pipe 6 and to axial power transmission in seal ring 2, make that the seal rings 2 in the bellmouth 12 are combined closely with pipes 6.
Wherein, described seal ring 2 is a rubber seal, is flexible sealing, and sealing intensity can be in very large range adjusted.
The utility model should consider to be provided with the end buttress, to offset the thrust that pipeline internal medium produces as use (being that the pipeline distal end is used) at pipe end.
Need to prove at this, the number of regulating bolt hole is not limited to described eight of present embodiment, the effect of regulating bolt is that it is by compressing the adjusting pressure ring to the adjusting of seal ring enforcement sealing intensity, therefore its concrete number can be decided according to the production specification of the utility model tray expansion bend, the big words of the utility model tray expansion bend size, the number of regulating bolt hole can be suitably some more, the utility model tray expansion bend size is little, and the number of regulating bolt hole can be suitably less.
