Abstract
The utility model relates to an extension pipe joint, two pipeline that meet including the mouth of pipe, the two pipeline inboard assembly tubular joint that slides that meets, at least, it has two ring groove s coaxial with tubular joint to open on the tubular joint outer wall, all is fixed with the sealing washer that is used for with the laminating of pipeline inner wall in every ring groove, and every pipeline tip covers a sealing washer at least. The utility model discloses at the two pipeline inboard assembly tubular joint that slides that meets, can follow tubular joint during pipeline the thermal expansion and slide, tubular joint provides the removal space for pipeline, and the pipeline's of fine solution expend with heat and contract with cold problem is fixed with the sealing washer that is used for with the laminating of pipeline inner wall on the tubular joint outer wall, realize sealed effect, has prevented gaseous outer hourglass, convenience safe in utilization.
Description
Technical field
The utility model relates to the connected element of the gas heating equipment pipes such as old factory building in a kind of winter, indoor, storehouse, is specifically related to a kind of pipe expansion joint.
Background technique
A lot of gas kitchen pipe joint complex structure on market today, because heating in winter is relatively more frequent, pipeline is heated and expands with heat and contract with cold often, and actual experimental test is not carried out in a lot of adapter, thus causes adapter to produce distortion; Some joint additionally uses welding technique in addition, connects the deformational displacement cannot offset and expand with heat and contract with cold and produce like this, sometimes there will be crack in joint, have a strong impact on use safety.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of pipe expansion joint, and it can effectively prevent pipeline junction from occurring because of the distortion caused of expanding, and use safety is easy for installation.
For achieving the above object, the technological scheme that the utility model is taked is:
A kind of pipe expansion joint, comprise two conveyance conduits that the mouth of pipe connects, described two conveyance conduit connecting part inner slide assemble a tubular configured joint, described tubular configured joint outer wall at least has two annular slots coaxial with tubular configured joint, all be fixed with the seal ring for fitting with conveying pipeline inner wall in each annular slot, each conveyance conduit end at least covers a seal ring.
In the middle of described tubular configured joint, outer wall is provided with circular protrusion, and described annular slot is distributed in circular protrusion both sides.
Described tubular configured joint adopts galvanized pipe to make.
Described seal ring adopts asbestos or high-temperature resistance plastice to make.
The length of described tubular configured joint is 2cm-20cm.
The utility model assembles a tubular configured joint in two conveyance conduit connecting part inner slide, can slide along tubular configured joint during conveyance conduit expanded by heating, tubular configured joint is that conveyance conduit provides mobile space, the problem of expanding with heat and contract with cold of the conveyance conduit of good solution, tubular configured joint outer wall is fixed with the seal ring for fitting with conveying pipeline inner wall, realize sealing effect, prevent gas to leak outside, safe and convenient to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of entirety of the present utility model.
Fig. 2 is the structural representation of fractionation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of pipe expansion joint, comprise two conveyance conduits 1 that the mouth of pipe connects, described two conveyance conduit 1 connecting part inner slide assemble a tubular configured joint 3, the external diameter of tubular configured joint 3 is slightly less than the internal diameter of conveyance conduit 1, such tubular configured joint 3 can slide in conveyance conduit 1, convenient installation.Described tubular configured joint 3 outer wall at least has two annular slots 4 coaxial with tubular configured joint, the seal ring 2 for fitting with conveying pipeline inner wall is all fixed with in each annular slot 4, seal ring 2 and annular slot 4 inwall are fitted, prevent gas leakage, can according to the sealability of different conveyance conduit, select suitable annular slot 4 quantity, applied range.Each conveyance conduit end at least covers a seal ring, makes to be tightly connected between each conveyance conduit and tubular configured joint 3.
The middle outer wall of tubular configured joint 3 is provided with circular protrusion 5; described annular slot 4 is distributed in circular protrusion both sides; circular protrusion 5 can be stuck in the port of conveyance conduit 1; can prevent tubular configured joint 3 from entering completely in one of them conveyance conduit and departing from another conveyance conduit like this; circular protrusion 5 pairs of tubular configured joints 3 play position-limiting action; circular protrusion 5 can prevent two conveyance conduits from directly docking collision on the other hand, plays a protective role to conveyance conduit.
Tubular configured joint 3 adopts galvanized pipe to make, and it has higher heat-resisting quantity, anti-oxidation, long service life.
Seal ring 2 adopts asbestos or high-temperature resistance plastice to make, and it is high temperature resistant, long service life.
The length of tubular configured joint is 2cm-20cm, can be 2cm, 5cm, 10 or 20cm, can select, to guarantee that tubular configured joint is socketed with conveyance conduit all the time according to conveyance conduit expanded by heating amount size.
When hot gas passes through, tubular configured joint 3 can swell, and fits tightly at diametric(al) tubular configured joint 3 and conveying pipeline inner wall, and seal ring 2 is also swollen simultaneously, realizes sealing effect, prevents gas to leak outside; On length direction, displacement is carried out along tubular configured joint 3 because heat expansion can make conveyance conduit extend, can according to the length of different combustion temperature, the different selection tubular configured joint 3 of conveyance conduit stretching rate, when ensureing that its ignition heat expands, elongatedness direction can not depart from seal ring 2, reaches the thermal expansion of offsetting pipeline and producing because of burning with this.
Claims (5)
1. a pipe expansion joint, comprise two conveyance conduits that the mouth of pipe connects, it is characterized in that: described two conveyance conduit connecting part inner slide assemble a tubular configured joint, described tubular configured joint outer wall at least has two annular slots coaxial with tubular configured joint, all be fixed with the seal ring for fitting with conveying pipeline inner wall in each annular slot, each conveyance conduit end at least covers a seal ring.
2. pipe expansion joint according to claim 1, is characterized in that: in the middle of described tubular configured joint, outer wall is provided with circular protrusion, and described annular slot is distributed in circular protrusion both sides.
