Abstract
A novel expansion joint for transportation pipelines has the advantages of firm performance, favorable sealing effect and long service life. The utility model has a technical scheme that the novel expansion joint comprises an inner sleeve pipe, an outer sleeve pipe and a connecting flange. The utility model is characterized in that the outer wall of the inner sleeve pipe is provided with a sealing groove which is provided with a sealing device inside. Because the structure effectively solves the heat-expansion and cold-contraction problem for pipeline transportation, the novel expansion joint can ensure pipeline transportation to safely proceed for long. The utility model has the advantages of simple structure, strong pressure resistant capability, little conveying resistance and long service life.
Description
Technical field: the utility model relates to a kind of conveyance conduit expansion joint joint.
Technical background: in recent years, along with improving constantly of science and technology, the technology of utilizing pipeline to carry out FLUID TRANSPORTATION constantly increases, developed into all trades and professions at present, and conveying material also is diversified, in line transportation, often relates to the defeated material temperature variation of pipe interior, or because seasonal variations produces the variation of ambient temperature, the problem of expanding with heat and contract with cold is still the problem that specially defeated pipeline must solve, otherwise the destruction that will produce pipe-line system causes the accident.
For many years, people study the expand with heat and contract with cold problem of pipe expansion joint of all kinds with the solution pipeline, as:
One, with U type pipe expansion of metal joint, the problem of expanding with heat and contract with cold of the pipeline of solution, but its transporting resistance is big, serious wear, and life cycle is short, because of floor space is big, expends amount of metal and is eliminated greatly and gradually.
Two, use rubber expansion joint, because of withstand voltage low, Applicable scope is little.
Three, the expansion joint made from some other measure (as corrugated expansion joint) all because of or such problem undesirable.
The model utility content: the technical problems to be solved in the utility model provides a kind of not only firm, durable, but also novel pipeline expansion joint easy to maintenance, simple in structure.Technological scheme: have inner sleeve, outer sleeve, adpting flange, it is characterized in that: have seal groove at the inner sleeve outer wall, seal arrangement is housed in the groove.Beneficial effect:, can guarantee the operation of pipeline transport long-term safety because the utility model structure has effectively solved the hot swollen shrinkage problem of line transportation.The utility model simple structure, voltage endurance capability is strong, and transporting resistance is little, and the life-span is long.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A portion enlarged view of Fig. 1.
Embodiment: as shown in Figure 1, have inner sleeve 2, outer sleeve 1, adpting flange 3, as shown in Figure 1 and Figure 2, have seal groove, seal arrangement 4 is housed in the groove at the inner sleeve outer wall.The inner sleeve outer wall has three seal grooves in the present embodiment.Seal arrangement 4 can be selected y-type seal ring for use for y-type seal ring or 0 RunddichtringO in the present embodiment.Be provided with holding down bolt 5 between the below of inner sleeve 2 and the adpting flange 3, be used for the flexible scope of confined expansion joint.Y-type seal ring improves sealing effect when manifold pressure raises, and guarantees the leakproofness of pipe-line system, has improved utilization ratio.
