Abstract
Disclosed is an O shape compensator used on pipelines in metal pipeline construction, which solves the problems that the original compensator has excessive welding craters and excessive joints of a thermal insulation layer and a waterproof layer. The utility model is characterized in that the two ports of a circular ring shape metallic pipe (1) are arranged in stagger and is prolonged; a thermal insulation layer (2) and a waterproof layer (3) are sequentially arranged outside of the metallic pipe (1); the end of the waterproof layer (3) is sleeved with a waterproof cap (4). The compensator can be made without welding crater, the thermal insulation layer and the waterproof layer can be made without joint, so that the integral quality is improved and the using time is prolonged. The loss of hydraulic pressure is small, the conveying efficiency is increased effectively, and thereby the utility model can satisfy the compensation of the length change of the metallic pipeline caused by expanding with heat and contracting with cold.
Description
Technical field:
The utility model relates to compensator on a kind of long distance pipeline, belongs to " O shape " compensator on the pipeline.
Background technique:
Compensator is the long defeated common components of metallic conduit in construction on the pipeline.Pipeline compensator in the past is a ∩ shape structure, is welded into 3 sections straight tubes, 4 elbows, has so just caused weld bond many, and it is many that insulation water-proof layer connects stubble, and total quality be difficult to guarantee, liquid in pipe flow through compensator to turn 4 90 ° curved, hydraulic slip is higher.
Summary of the invention:
In order to overcome the deficiency of above-mentioned background technology, the utility model provides " O shape " compensator on a kind of pipeline, and this compensator does not only have weld bond, and its insulation water-proof layer do not connect stubble, can effectively extend working time.
The purpose of this utility model can be achieved through the following technical solutions: compensator is the ring compensator on the pipeline, be that metal tube is made ring, the two ends mouth of pipe staggers and prolongs, watertightness barrier is made the ring two-port and is staggered, be placed in the periphery of circular ring metal pipe, pour into thermal insulating material in the toroidal cavity of circular ring metal pipe and ring watertightness barrier, the end of watertightness barrier is with tarpaulin.
The utility model can have following effect compared to prior art: owing to adopt " O shape " compensator, the circular ring metal pipe can realize that not having weld bond makes, and thermal insulation layer, watertightness barrier can be realized not having and connect stubble, and total quality improves, and can effectively extend working time.The flow through route of compensator of fluid is a circumferential, and the hydraulic slip of flowing through is little, can effectively improve transfer efficiency." O shape " compensator has bigger elasticity, can satisfy the compensation of metallic conduit length change when expanding with heat and contract with cold.
Description of drawings:
Accompanying drawing 1 is a plan view of the present utility model;
Accompanying drawing 2 is plan views of accompanying drawing 1.
1-metal tube among the figure, 2-thermal insulation layer, 3-watertightness barrier, 4-tarpaulin.
Embodiment:
The contrast accompanying drawing will the utility model is described in further detail:
As Fig. 1 in conjunction with shown in Figure 2, the metal tube 1 of this compensator is a ring, and the two-port of metal tube 1 staggers and prolongs, and can realize that not having weld bond makes, and thermal insulation layer 2 and watertightness barrier 3 are arranged outside metal tube 1 successively, make thermal insulation layer 2, watertightness barrier 3 can realize not having and connect stubble, total quality improves, and can effectively extend working time, and thermal insulation layer 2 places in the toroidal cavity of metal tube 1 and watertightness barrier 3, the material of thermal insulation layer 2 is combined polyether or isocyanates, and watertightness barrier 3 ends are with tarpaulin 4.As seen the flow through route of compensator of fluid is a circumferential, and the hydraulic slip of flowing through is little, can effectively improve transfer efficiency, also " O shape " compensator bigger elasticity is arranged, can satisfy the compensation of metallic conduit length change when expanding with heat and contract with cold.Use the same with existing compensator.
Claims (2)
1, " O shape " compensator on the pipeline of using in a kind of metallic conduit construction, it is characterized in that: the two-port of circular ring metal pipe (1) staggers and prolongs, thermal insulation layer (2) and watertightness barrier (3) are arranged outside metal tube (1) successively, and watertightness barrier (3) end is with tarpaulin (4).
2, " O shape " compensator on the pipeline according to claim 1 is characterized in that: thermal insulation layer (2) places in the toroidal cavity of metal tube (1) and watertightness barrier (3).
