Abstract
The utility model relates to a gas pipeline flexible compensator belongs to gas pipeline technical field. Mainly comprises a stainless steel corrugated pipe, two end connecting pipes and a protective sleeve. One end of the connecting pipe is a cylindrical light pipe, the pipe orifice of the other end of the connecting pipe is provided with taper pipe threads, and the protective sleeve consists of a large corrugated pipe and a movable ring. The movable ring is sleeved on the connecting pipe, and the inner diameter of the large corrugated pipe is larger than the outer diameter of the working corrugated pipe inside the large corrugated pipe. The outer surface of the connecting pipe positioned outside the movable ring is provided with a limit point. The utility model saves the connection of flanges and bolts, is convenient to assemble and disassemble and has reliable sealing; the corrugated pipe protective sleeve has good flexibility, small bending rigidity and free sliding, and the compensation effect is obviously improved.
Description
The utility model relates to a kind of corrugated expansion joint, especially for the flexible compensator of gas pipe line, belongs to gas-pipe line device technique field.
Along with the raising of development of economic construction and people's living standard, large quantities of multilayers, tall building are built in succession.Because the coastal area particularly is on the soft foundation on ground such as Shanghai, unequal settlement of building usually causes the fracture of gas house-service pipeline pressurized, has serious consequences.Therefore, need to install flexible compensator in the gas pipeline with compensating action.The corrugated expansion joint that generally adopts mainly is made of adapter, bellows and protecting jacket at present.Be welded with flange in the adapter or be threaded, protecting jacket then adopts braiding net or steel pipe.Though this compensator can compensate the amount of deflection that building settlement causes, the loading and unloading difficulty, poor sealing, protecting jacket is flexible poor, influences compensation effect.
The purpose of this utility model is to overcome the deficiency of existing compensator, provides a kind of easy to loading and unloading, good airproof performance, the flexible compensator of the gas pipe line that compensation effect is good.
The technical solution of the utility model is: the flexible compensator of gas pipe line is made up of corrugated stainless steel tubing, two pipe nipples, protecting jacket main member.One pipe nipple is a garden cylindricality light pipe, and the mouth of pipe that the other end is taken over is provided with taper pipe thread, and protecting jacket is made of big bellows and loose collar.During assembling, garden cylindricality light pipe directly inserts in the seal ring of interface, and the taper pipe thread of the other end guarantees to connect reliably.Big bellows flexibility as the protecting jacket main body is good, flexural rigidity is little, improves compensation effect.
Above-mentioned loose collar is welded into one with big bellows point, and loose collar is sleeved in the adapter, and big inside diameter of bel is greater than the external diameter of its inside bellows, thereby protecting jacket can be free to slide on taking over.Simultaneously, the adapter outer surface that is positioned at the loose collar outside is provided with spacing point or limiting stopper, in case the departing from of protecting jacket.
Adopt said structure, the utility model saves flange and is connected with bolt, and is easy to loading and unloading, and taper pipe thread connects reliable, and sealing improves, and bellows protecting jacket flexibility is good, and flexural rigidity is little, free sliding, and compensation effect is significantly improved.
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
As figure, two pipe nipples 1 and 6 and small corrugated pipe, 5 the one-tenths sealed types welding of bellows of promptly working, taking over 1 is garden cylindricality light pipe, the mouth of pipe of adapter 6 is provided with taper pipe thread 7.Loose collar 3 is welded into one with big 4 of bellowss, constitutes protecting jacket jointly.Loose collar is sleeved in the adapter, and the internal diameter of bellows 4 is greater than the external diameter of bellows 5.Be positioned at 20mm place, the loose collar outside on the two pipe nipple outer surfaces and be provided with 4 spacing points 2 respectively.Bellows and loose collar are made by stainless steel, and two pipe nipples are by 20
#Steel is made.
