Abstract
The invention relates to a compensative pipeline repair device applicable to pipelines. To meet the requirements of repairing damage of compensators in pipeline network operation and performing simple welding for leakage of a pipeline network, a repair device needs to be compensative. Certain existing pipeline plugging devices can be used for pipeline leakage but cannot be substitute for compensators to absorb thermal displacement of the pipelines and cannot be used to repair leakage of the pipeline network caused by the damage of the compensators. Medium leakage from a leak point can be plugged in such manners that the leak point is enclosed by a cavity formed by a core tube, a seal baffle ring, a housing and a connecting ring, the space formed by a guide flange, a seal flange, the housing and the seal baffle ring is filled with packing and the guide flange and the seal flange are connected via bolts to compress the packing. A drain valve is added to the housing to prevent the medium from flowing to the welding position to affect welding during assembly and welding of parts. The drain valve is closed after assembly finishes, so that the medium in a pipeline is prevented from leaking. The core is capable of moving with respect to the housing and the connecting, so that the compensation requirement of a compensator is met. Therefore, the problem that the damaged compensator cannot be repaired in pipeline network operation is solved substantially, stoppage of the pipeline network caused by the damage of the compensator is avoided, and loss caused by stoppage is decreased.
Description
Technical field: what the technology of the present invention related to is to be fit to a kind of band compensation device for repairing pipeline of installing in the pipeline in each field.
Background technique: as thermal compensation and damper element, compensator is used very extensive in pipeline, at the heat distribution pipe network of centralized heating project; Play an important role especially in the smoke wind pipe in power plant, steel mill, cement plant and powder feeding pipes.Compensator has the advantages such as simple, little to equipment thrust, saving space is installed, but compensator is as ducted weak link simultaneously, many reasons can cause the leakage of compensator to damage, and the damage of compensator causes the out of service of pipe network, and the loss that causes thus can't be estimated.So when pipe network occurs leaking and can not simply weld, only have repairing apparatus just can meet the demands with compensation performance.
In pipe network, compensator damages and can not repair, can only change, but can not change compensator under the pipe network working condition, although some Pipe leakage stoppers can solve the pipe leakage problem, but the thermal walking of compensator extraction duct can not be replaced, the leakage that in pipe network, the compensator damage causes can not be repaired.
Summary of the invention: for the problems referred to above, we are through research practice for many years, invented a kind of band compensation device for repairing pipeline, fundamentally solved the problem that the compensator damage can not be repaired in pipe network operation, prevent from causing the out of service of pipe network because compensator damages, reduced the loss of stopping transport and causing.
the specific practice of this patent is, core pipe 1 is connected with pipeline 12, connecting ring 11 is connected with pipeline, the compensator that lays respectively at damage maybe needs leakage point 13 two ends that compensate, core pipe 1, seal stopper ring 8, outer cover 10, the cavity that connecting ring 11 forms is with leakage point place's encirclement, guide flange 5, sealing flange 6, outer cover 10, the space-filling stuffing box packing of seal stopper ring 8, by bolt 2, the medium that the mode shutoff leakage point of guide flange 5 press seal fillers 7 flows out, the effect of discharging valve 9 is to prevent from flowing to welding position impact welding in each parts assembly welding process medium, after all assembling is completed, discharging valve 9 cuts out, guarantee that pipeline internal medium does not leak, while core pipe 1 and outer cover 10, connecting ring 11 can relative movement, satisfy the compensation requirement of pipe network.
Description of drawings: the semi-section schematic diagram after Fig. 1 band compensation device for repairing pipeline processing assembling, Fig. 2 band compensation device for repairing pipeline is processed into two-part upper half part schematic diagram, the schematic diagram after Fig. 3 band compensates device for repairing pipeline and pipeline is connected.
specific implementation method: with reference to accompanying drawing 1, first will be with the whole machine shaping of each parts of compensation device for repairing pipeline, do preservative treatment after the 1 outer surface processing of core pipe, seal stopper ring 8, outer cover 10, sealing flange 6, connecting ring 11, two discharging valves 9 are welded into a combiner, combiner after welding is equally divided into two-part, every part is with a discharging valve 9 and cutting surface can not be passed through the bolt hole position of sealing flange 6, with core pipe 1, guide flange 5 also on average cuts into two-part, the cutting surface of guide flange 5 can not be by the bolt hole position, the cutting surface of each parts is processed bevel for welding as requested, form the two-part as accompanying drawing 2 signals.Core pipe 1 after cutting is put into the compensator movable end of Pipeline damage, assembly welding core pipe 1, the range compensator movable end reserves welding apart from locating core pipe 1 and with pipeline 12 of pipeline thermal displacement simultaneously, with the weld bond equating, the pipeline compensator that two combiners that seal stopper ring 8, outer cover 10, sealing flange 6, connecting ring 11, two discharging valves 9 are welded into are positioned to damage maybe needs the leakage point position that compensates, after discharging valve 9 is opened with two parts assembly weldings, the weld seam of equating seal stopper ring 8, the installation direction of combiner as shown in Figure 3.Then with connecting ring 10 and pipeline 12 welding, two-part guide flange is installed to core pipe 1 end and assembly welding on pipeline according to cover shown in accompanying drawing 3, the equating weld seam, with guide flange 5,, the stuffing box packing such as filled stone disc root in the space of outer cover 10, seal stopper ring 8, guide flange 5, sealing flange 6 are connected the press seal filler by bolt 2, nut 3, pad 4, at last discharging valve 9 cuts out, thereby reach leakage point by the purpose of shutoff and thermal walking that can extraction duct.
