Abstract
The utility model relates to a corrugated-pipe sleeve barrel unit combined compensator, which is the improvement of the structure of the telescoping compensation element of a heat distribution pipeline. The utility model is characterized in that a stainless steel corrugated-pipe is isolated from the outside by a left flange, an outer guard sleeve pipe and an insertion ring. The stainless steel corrugated pipe can be divided into tow segments which are welded together by two middle flanges. The utility model has the advantages that a complete full control of access sealed leak-proof structure is adopted, the problems of the infiltration of the chloridion of the stainless steel pipe and the corrosion can be preferably solved, the emergency stop because of the overflow of the medium in the pipeline caused by emergency unexpected leakage of the corrugated pipe can be prevented, the utility model is safe, and the construction cost can be decreased.
Description
The utility model relates to a kind of improvement to heat distribution pipeline flexible compensation element structure, is a kind of bellows sleeve sleeve combined compensator specifically.
Though because single sleeve-type expansion joint is simple in structure, cost is low, and resisting corrosion of chlorine ion, need often maintenance, thereby need establish inspection shaft, in full direct-burried pipe network, can't use; For single corrugated stainless steel tubing compensator, its Austenitic Stainless Steel is anti-chlorine ion electrolytic corrosion and stress corrosion not, causes working life far away from designing fatigue life.China's Coastal Areas underground water contains high chloride ion, and particularly high temperature steam pipeline under temperatures involved, quickens chlorion to stainless various corrosion, and corrugated stainless steel tubing is leaked easily, causes shutdown, needs to change the corrugated stainless steel tubing compensator.
The utility model purpose is to overcome the shortcoming in the above-mentioned technology, compensator to single formula structure makes improvements, a kind of bellows sleeve sleeve combined compensator is proposed, can solve the infiltration and the etching problem of single corrugated stainless steel tubing compensator chlorion preferably, and be used for the be essential complete straight reason of the pipe network technical field of compensation of steam and one, can exempt to establish in the inspection, reduce engineering cost, reduce thermal energy consumption.
The utility model purpose is realized by following technological scheme: this is used for by the bellows sleeve sleeve combined compensator at steam line, its corrugated stainless steel tubing left end and left flange and left end pipe are fixed together, corrugated stainless steel tubing right-hand member and right flange and right-hand member pipe are fixed together, water conservancy diversion is sleeved in the corrugated stainless steel tubing, and with corrugated stainless steel tubing medium importer to an end be welded to connect, the oversheath pipe box is in left flange and right flange periphery, left end and left flange periphery are welded to connect, packing ring is enclosed within on the right-hand member pipe, oversheath pipe right-hand member and packing ring are welded to connect, by left flange, oversheath pipe and packing ring are kept apart the corrugated stainless steel tubing and the pipe external world.
Corrugated stainless steel tubing is divided into two sections, is connected together by two spacer flanger welding.Two spacer flangers play the guiding role to corrugated stainless steel tubing, prevent to cause wear-out failure because of the axial unstability of corrugated stainless steel tubing contacts with the oversheath inner tube wall.If the structure length of bellows is shorter, also can remove two spacer flangers, with a whole bellows.Between right flange cylindrical and two spacer flanger cylindricals and oversheath inner tube wall, leave the gap that to slide, when owing to during temperature variation, can eliminate the flexible of pipeline axial with the displacement of right-hand member pipe.Be enclosed within the packing ring on the end pipe, seal ring be pressed in the packing ring by gland and bolt.Packing ring has seal action.According to using actual demand, whether decision needs to add last layer waterproof, lagging casing in bellows sleeve sleeve combined compensator outside.
Medium flows into from the left end pipe, the water conservancy diversion cover can reduce the impact of medium to bellows, when right-hand member pipe external pipe is subjected to thermal stretching, the right-hand member pipe will overcome with packing ring in the friction of seal ring, because of right flange and two spacer flangers and oversheath inner tube wall leave glade plane space, there are not other resistances, right flange and spacer flanger are moved to the left, the compression corrugated stainless steel tubing is compensated the thermal stretching that is subjected to of pipeline.Because it is totally-enclosed that oversheath pipe, left flange, packing ring, the gland of packing ring, seal ring have carried out corrugated stainless steel tubing, prevents that reliably the high underground water of extraneous chloride ion content from entering, and carries out electrolytic corrosion and stress corrosion to corrugated stainless steel tubing.If in a single day seepage takes place corrugated stainless steel tubing, the pipeline medium can be sealed up by packing ring etc., can be not excessive, and therefore can not cause and stop in emergency.
The utility model has the advantages that the compensator of two kinds of single formula structures is combined, adopt totally-enclosed anti-leakage structure, the chlorion that has solved preferably corrugated stainless steel tubing infiltrates and etching problem, and can prevent to make because of the unexpected seepage of corrugated stainless steel tubing the generation of the excessive problem of stopping in emergency of pipeline medium.Safe and reliable to operation, long service life, corrosion resistance is good.Can be used for steam, heat supply, and the compensation of pipeline of poisonous and harmful medium, be particularly useful for to exempt to establish inspection shaft in the complete straight reason pipe network system of the high rugged environment of coastal area chloride ion content, reduce engineering cost, reduce thermal energy consumption.
Embodiment of accompanying drawings:
Fig. 1 is bellows sleeve sleeve combined compensator structure figure,
Left end pipe (12) is the normal carbon steel pipe of 100 millimeters of latus rectums with right-hand member pipe (1), and by flowing into 300 ℃ of steam with the stainless steel diversion cover (13) that welds downlink connection at flange (11), vapor pressure is 1.6MPA.Corrugated stainless steel tubing (10) is two sections, is made by the corrosion resistant plate of two layer of 0.5 millimeters thick respectively, and two sections bellowss are welded to connect by spacer flanger (8), (9) respectively and are one.Oversheath pipe (7) is 8 millimeters thick seamless steel pipes.The seal ring (4) that expanded graphite is made is equipped with in the inside of packing ring (5), it compressed by bolt (3) by gland (2), and withstand voltage 6MPA, serviceability temperature is 550 ℃.Oversheath pipe (7) two ends weld together with steel left side flange (11) and steel packing ring (5) respectively, carry out corrugated stainless steel tubing (10) totally-enclosed.Right-hand member pipe (1) is connected with corrugated stainless steel tubing (10) by right flange (6).
