Abstract
The utility model discloses a kind of board-like expansion joints, including two pieces of connecting plates, two pieces of backing plates and gasket；Wherein, two pieces of connecting plates are arranged in parallel, and two pieces of backing plates are equipped between two connecting plates, are equipped with gasket between two backing plates, and the connecting plate, backing plate are equipped with bolt hole on gasket, and three is connected by bolt and nut.Connecting plate is the intermediate tablet hollowed out, and knockout shape is identical as expansion joint institute's connecting leg road cross sectional shape, hollows out area and is slightly less than pipeline section area；Backing plate setting is welded in connecting plate outer edge with connecting plate, and backing plate keeps certain distance with pipeline outer wall.The utility model baffle arrangement is simple, and manufacture is easy for installation, and with short production cycle, production cost is low.
Description
Technical field
The utility model is related to conduit fittings technical field, especially a kind of expansion joint, more particularly to a kind of board-like swollen
Swollen section.
Background technology
Expansion joint be for absorbing due to expanding with heat and contract with cold etc. caused by pipeline or the device of equipment size variation.Adding
In heat furnace system, there are many pipeline medium temperature it is less high, the thermal expansion amount of pipeline is also less big, if be all made of conventional
There is manufacture complexity in bellows-type expansion section, the manufacturing cycle is long, and production cost is high although preferable effect can be obtained
The problem of, therefore, it is necessary to develop a kind of expansion joint simple in structure, production cost is low.
Utility model content
In view of this, the utility model provides a kind of simple in structure, manufacture is easy for installation, low board-like swollen of production cost
Swollen section.
In order to achieve the above objectives, a kind of board-like expansion joint technical solution provided by the utility model is as follows：
A kind of board-like expansion joint, including two pieces of connecting plates, two pieces of backing plates and gasket.Two pieces of connecting plates are arranged in parallel, and two connect
It is equipped with two pieces of backing plates between fishplate bar, gasket is equipped between two backing plates.The connecting plate, backing plate are equipped with bolt hole on gasket, and three
Person is connected by bolt and nut.The connecting plate is the intermediate tablet hollowed out, knockout shape and the connected pipeline section shape of expansion joint
Shape is identical, hollows out area and is slightly less than pipeline section area.The backing plate setting is welded in connecting plate outer edge with connecting plate,
Backing plate keeps certain distance with pipeline outer wall.
The connecting plate is rectangle or circle.
The connecting plate, backing plate are steel plate.
The gasket is the fine gasket of pottery.
The connecting plate is connect by welding with pipeline outer wall.
The beneficial effects of the utility model are：Simple in structure, manufacture is easy for installation, and with short production cycle, production cost is low.
Description of the drawings
By reading the detailed description of hereafter preferred embodiment, various other advantages and benefit are common for this field
Technical staff will become clear.Attached drawing only for the purpose of illustrating preferred embodiments, and is not considered as to this practicality
Novel limitation.
Fig. 1 is a kind of front view of typical embodiment of the utility model；
Fig. 2 is the front view of another typical embodiment of the utility model；
Fig. 3 is the schematic diagram of A-A sections in Fig. 1, Fig. 2.
In figure, 1, backing plate one, 2, connecting plate one, 3, pipeline one, 4, gasket, 5, backing plate two, 6, bolt, 7, nut, 8, even
Fishplate bar two, 9, pipeline two.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Embodiment 1
As shown in attached drawing 1 and attached drawing 3, when 29 rectangular cross-section of pipeline 1 and pipeline, connecting plate 1 and connecting plate two
8 are respectively provided with rectangular, and centre hollows out, and knockout shape is identical as expansion joint institute's connecting leg road cross sectional shape, hollows out area and is slightly less than pipe
Road area of section.Connecting plate 1, connecting plate 28 are connect with pipeline 1 and 29 end face of pipeline by welding respectively.Pad
Plate 1 and backing plate 25 are separately positioned on the outer edge of connecting plate 1 and connecting plate 28, connect by welding.Pad
Plate 1 and backing plate 25 keep certain distance with pipeline outer wall, to ensure that connecting plate has enough curved in length to carry out extraction duct
It thermally expands.Gasket 4 is arranged between backing plate 1 and backing plate 25.Connecting plate 1, connecting plate 28, backing plate 1 and backing plate 25,
It is equipped with bolt hole on gasket 4, they are fixedly connected by bolt 6 with nut 7.
When thermal medium flows through pipeline, expansion joint outer end is fixed under the action of bolt and nut, and inner end pipeline is heated
Expansion, two connecting plate inner ends are bent to two connecting plate middles, the thermal expansion of extraction duct.The utility model is simple in structure, system
Make easy for installation, with short production cycle, production cost is low.
Embodiment 2
As shown in attached drawing 2 and attached drawing 3, when pipeline 1 and 29 section of pipeline are round, connecting plate 1 and connecting plate two
8 are all provided with and are set to circle.Other content is substantially the same manner as Example 1, and which is not described herein again.
Although the utility model is described above in association with figure, the utility model is not limited to above-mentioned tool
Body embodiment, the above mentioned embodiment is only schematical, rather than restrictive, the ordinary skill people of this field
Member, in the case where not departing from the utility model aims, can also make many variations under the enlightenment of the utility model, these
It belongs within the protection of the utility model.
