A kind of heating system direct-burried transmission and distribution network is made of some branch lines, comprises a main in each branch line, and this main is interconnected to constitute by elbow by one group of horizontal stroke, vertical pipe, goes out one group of arm in this main top set; Described each arm connects by parallel threeway with main.
The two ends of described one section main have two elbows, and this section main is provided with the arm that is positioned at non-mid point, add the compensation elbow at this arm with the opposite side symmetric position place of elbow closely.
In the above-mentioned heating system direct-burried transmission and distribution network, the compensation that adds can be a Π type elbow with elbow; Also quarter bend elbow, during connection, the preceding connection straight tube of described Π type elbow with after be connected straight tube and be positioned on the coaxial line; The preceding connection straight tube of described quarter bend elbow with after be connected that straight tube is parallel to each other but on the non-coaxial line.When elbow location point place need establish arm, increase two compensation elbows newly, the arm that need are established is arranged on two centre positions that compensate elbows that increase newly.
Also can utilize prior art simultaneously, compensator and anchor block are set thinking that the place that is necessary still keeps, new aging method combination is to obtain better effect.
In pipe-line system, elbow is the pipe fitting that changes the pipeline direction.The utility model utilizes some elbows cleverly, and redeeming in the direct-burried pipeline that lays makes the displacement that this pipeline expands with heat and contract with cold be effectively controlled.Opened up new laying method, promptly well solved the displacement that brings because of expanding with heat and contract with cold and caused the junction pipe fitting to damage problem.
It is the hot water of temperature between 50～150 ℃ that the utility model is specially adapted to heating medium.
The utility model has the advantages that:
1, adopt parallel threeway to connect and increase the means of compensation elbow, the displacement of expanding with heat and contract with cold of main and arm junction is reduced, pipe fitting is not fragile.
2, elbow is conventional pipe fitting, handling ease, long service life, and low cost of manufacture.
3, minimizing or not using compensation equipment in a large number can reduce the engineering construction cost significantly, increase the pipe network life-span.
4, reduce in a large number or do not use anchor block, make civil engineering few, take up an area of fewly, speed of application is fast.
5, the utility model increases elbow and can reduce or do not use anchor block, compensator, by contrast, small investment not only, the construction period also can shorten greatly, remarkable in economical benefits.
