Abstract
The utility model relates to a wall-penetrating (well wall) sealer for various thermal directly-embedded pipelines, in particular to a novel well wall sealer which is made by arranging a corrugated sealing compensator in the internal layer of a sleeve sealing compensator. The sleeve compensator comprises a steel guiding pipe which is sleeved with an external sleeve pipe outside; a guiding ring anda sealing material are arranged between the external pipe and the steel guiding pipe; a sealing ring is arranged at an end; a connection internal ring plate is arranged on the internal wall of one end of the steel guiding pipe and movably connected with one end of the corrugated sealing compensator in the steel guiding pipe; the corrugated sealing compensator is made by the connection of a corrugated pipe sleeved outside a core pipe, and a connection pipe; and the end of the connection rod at the other end of the corrugated sealing compensator is fixedly connected with an external ring plate.The sleeve compensator of the utility model compensates the axial thermal displacement of the steel guiding pipe, and the sealer prevents underground water from pouring into a well; and the corrugated compensator compensates the axial thermal displacement and the radial structural displacement of a work pipe and prevents deposited water or moisture from reversely pouring into a thermal insulationlayer to influence the quality of thermal insulation, thereby achieving more reliable work and longer service life.
Description
Technical field
The utility model relates to the pressure piping element, is heating power directly buried pipeline (borehole wall) through walls sealing and heat compensating unit.
Background technique
The heating power directly buried pipeline is because when passing through the borehole wall, steel conduit and core pipe move under thermal expansion, so steel conduit and the borehole wall have relative displacement.In order to prevent that underground water from entering the well chamber, if steel conduit is enclosed in the borehole wall or the wall, under the effect of heat expansion power, can destroy the wall or the borehole wall, at pipe interior because the temperature difference of core pipe and steel conduit is unequal, core pipe and steel conduit also have relative displacement, generally the core pipe is only done axial displacement, and the existing axial displacement of core pipe also has lateral displacement under special circumstances, rainwater also can occur simultaneously and pour into the thermal insulation layer that pours in down a chimney inside, inlet pipe road behind the well chamber.Therefore, should guarantee the relative displacement of core pipe and steel conduit, guarantee seal action again.China's utility model patent Well-wall sealer (patent No.: 200520089531.6), there are the anticorrosion defective of outer ripple compensator and the limited deficiency of compensation range of Internal compensator, particularly in the coastal area, owing to the higher life-span that reduces bellows of chlorine ion concentration in the underground water.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of novel Well-wall sealer is provided, and External compensator is anticorrosion, and the compensation range of Internal compensator is big, can carry out axially and radial compensation the function and the effect that have improved Well-wall sealer.
The technological scheme that the utility model is adopted for achieving the above object is: novel Well-wall sealer, it is equipped with ripple sealing compensation device by sleeve seal compensator internal layer forms, sleeve expansion joint is the outer suit outer sleeve of steel conduit, guide ring and sealing material are housed between outer sleeve and the steel conduit, seal ring is equipped with in the termination, steel conduit one end inwall has the connection inner ring plate, ripple sealing compensation device one end that connects in inner ring plate and the steel conduit flexibly connects, ripple sealing compensation device is to be sleeved on core pipe outer bellows and connecting tube to connect and compose the fixedly connected outer ring plate in ripple sealing compensation device the other end connecting tube termination.
Described outer sleeve is set with the dash thrust disc outward.
Described steel conduit is set with dust ring outward, between dust ring and the outer sleeve dirt-proof boot is housed.
The seal ring that install described outer sleeve and steel conduit termination is hermetically sealed case ring and graphite-seal ring double seal ring.
Described sealing material is for annotating packing envelope material, and outer sleeve is provided with syrup filling tip.
Described steel conduit adopts the steel conduit of outer surface through overvulcanization and anti-corrosion treatment.
The utility model is combined by sleeve seal compensator and two kinds of compensators of ripple sealing compensation device.A sleeve expansion joint is installed between the borehole wall (wall) and steel conduit, and compensation seals simultaneously from the underground water in the soil and pours into the well chamber from the axial thermal walking of the relative borehole wall of steel conduit; A FlexbleJoint is installed between steel conduit and core pipe, compensation is from the axial thermal walking and the radial structure displacement of working pipe, cut off being communicated with of pipe interior heat-preservation cotton and well chamber simultaneously, to prevent to pour in down a chimney to the thermal insulation layer of pipe interior and influence the insulation quality from the ponding of well chamber interior or moisture.The utility model has been inherited the advantage of original Well-wall sealer, the outside seal FlexbleJoint is changed into sleeve expansion joint, its objective is that change can not resist the corrosion of chlorion because of the bellows material, particularly in the coastal area, owing to the higher life-span that reduces bellows of chlorine ion concentration in the underground water, and the sleeve expansion joint working surface has carried out sclerosis and preservative treatment, has prolonged the working life of compensator.It is more reliable that the utility model Well-wall sealer has work, the advantage of longer service life.Therefore, the utlity model has wide application prospect.
