Description
Technical field
The utility model relates to steam line interconnection technique field, and specifically a kind of direct-buried steam pipeline of high water level area is at the waterproof connecting structure of valve inspection Jing Chu.
Background technique
The no matter heating steam directly buried pipeline of northern area or the industrial direct-buried steam pipeline of southern area, when laying in the region that level of ground water is high, no matter how exquisite the design and construction of Civil Specialities are, in conduit running process, always there will be the situation of water of infiltration in pipeline valve inspection shaft.Thing followed consequence is, direct-burried steel jacket pipe thermal insulation layer is soaked, and causes pipeline heat loss to strengthen, and more serious consequence may affect the operation of pipeline.
In the running of directly buried pipeline, water string traditional in the conduit shaft in high water level area causes water-proofing material to lose efficacy because of various reasons after conduit running, normal effect cannot be played, What is more, and loosening appears in water string, to such an extent as to the water outside valve well infiltrates in well along the space between water string and steel bushing steel jacket.As shown in Figure 1, the water outside pipeline valve inspection shaft pours in down a chimney after in well, and the thermal insulation layer 3 between steel bushing steel jacket 21 and steel sleeve steel working pipe 5 can be immersed in water.Water outside the pipeline valve inspection shaft borehole wall 1 to the sealing material 22 applied thrust F between steel bushing steel jacket 21 and water string 2, can cause loosening of water string.
Model utility content
The purpose of this utility model is the waterproof connecting structure providing direct-buried steam pipeline at valve inspection Jing Chu, soaks thermal insulation layer and water string easily loosens under the thrust of the outer water of the borehole wall problem for the water solved outside pipeline valve inspection shaft after pouring in down a chimney in well.
The technical scheme in the invention for solving the technical problem is: direct-buried steam pipeline is at the waterproof connecting structure of valve inspection Jing Chu, it is characterized in that, it comprises water string, thermal insulating material, valve, steel sleeve steel working pipe, closure plate and bellows, described valve is arranged in pipeline valve inspection shaft, steel sleeve steel working pipe is connected with at the two ends of described valve, the borehole wall of described pipeline valve inspection shaft is provided with two water strings, and steel sleeve steel working pipe described in two extends through the outside to pipeline valve inspection shaft after corresponding water string; Thermal insulating material is filled with between described water string and steel sleeve steel working pipe, the water string being placed in pipeline valve inspection shaft outside is provided with bellows, between the water string end being placed in pipeline valve inspection shaft inside and steel sleeve steel working pipe, is provided with closure plate.
Further, the water string being placed in pipeline valve inspection shaft inside is also provided with bellows.
Further, between described closure plate and steel sleeve steel working pipe, seal ring is provided with.
The beneficial effects of the utility model are: the direct-buried steam pipeline that the utility model provides is at the waterproof connecting structure of valve inspection Jing Chu, by the setting of bellows, absorb the thrust be applied on water string, to alleviate the active force of water string to the borehole wall, prevent loosening between water string and the borehole wall.Closure plate between water string and steel sleeve steel working pipe, can prevent from pouring in down a chimney the thermal insulating material between the water soaking water string of valve inspection well inside, inlet pipe road and steel sleeve steel working pipe.
Accompanying drawing explanation
Fig. 1 is the waterproof connecting structure schematic diagram of existing direct-buried steam pipeline at valve inspection Jing Chu;
Fig. 2 is schematic diagram of the present utility model;
In figure: 1 borehole wall, 2 water strings, 21 steel bushing steel jackets, 22 sealing materials, 3 thermal insulating materials, 4 valves, 5 steel sleeve steel working pipe, 6 closure plates, 7 bellowss, F thrust.
Embodiment
As shown in Figure 2, the utility model mainly comprises water string 2, thermal insulating material 3, valve 4, steel sleeve steel working pipe 5, closure plate 6 and bellows 7, is described in detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 2, the valve 4 of steam line is arranged in pipeline valve inspection shaft, to facilitate installation, the maintenance of valve.Be provided with steel sleeve steel working pipe 5, two steel sleeve steel working pipe to be through on the borehole wall 1 of pipeline valve inspection shaft at the two ends of valve.Be provided with water string 2 in the outside of steel sleeve steel working pipe, between water string and steel sleeve steel working pipe, be filled with thermal insulating material, thermal insulating material can realize the insulation to steel sleeve steel working pipe.The outer wall of water string is fixed on the borehole wall, and good seal between the two, bellows 7 is connected at the two ends of each water string, bellows is can by the flexible pipe compressed, and bellows can restore to the original state when external force is cancelled, on each water string, the bellows at two ends is placed in the inside and outside both sides of pipeline valve inspection shaft respectively, closure plate 6 is provided with in the one end of the bellows being placed in pipeline valve inspection shaft inside, closure plate and bellows, good seal between closure plate and steel sleeve steel working pipe, the setting of closure plate can avoid pouring in down a chimney the thermal insulation layer between water soaking steel sleeve steel working pipe in inlet pipe road valve inspection well and water string, ensure the normal work of steam line.
When the water of pipeline valve inspection shaft outside is to water string applied thrust, water string can by this thrust in the borehole wall, the setting of pipeline valve inspection shaft outer corrugations pipe, the active force of water string to the borehole wall can be absorbed, and then avoid loosening between the excessive water string that causes of the active force of water string to the borehole wall and the borehole wall.Under the effect of external thrust; when steel sleeve steel working pipe moves in water string; the setting of the inner bellows of pipeline valve inspection shaft; water string can be made to adapt to the displacement of steel sleeve steel working pipe; namely when steel sleeve steel working pipe moves; under the effect of steel sleeve steel working pipe pulling force; the bellows of pipeline valve inspection shaft inside is stretched; to avoid steel sleeve steel working pipe to drive water string moving relative to the borehole wall with the frictional force between water string, protection water string is closely engaged on the borehole wall.For ensureing good sealing, between water string and steel sleeve steel working pipe, be provided with seal ring.
