Abstract
The utility model relates to an external compensator, particularly a pipe network compensator. The external compensator comprises a corrugated pipe and ring plates, wherein the corrugated pipe is connected with a steel pipe, and a coating device of the corrugated pipe is an outer sleeve pipe; the ring plate on both ends are connected with ribbed plates, and a tapered pipe is arranged outside the ribbed plates; the position between the tapered pipe and the outer sleeve pipe is sealed by a dustproof felt, and waterproof material is sealed on a welding seam between the corrugated pipe and the ring plate. Reducing pipes are arranged on the ring plates arranged on both ends of the utility model, therefore the end surfaces of the ring plates are avoided to contact soil, and the motion-resistance force of the pipelines and the soil is reduced. The contact area of a free end is enlarged, and the external compensator is sealing by a plurality of layers, therefore the silt is separated. The aluminum outer sleeve pipe is installed by using the method of protecting a cathode by losing an anode, therefore the pipes are protected effectively. Simultaneously, the welding seam of the corrugated pipe and the ring plate is sealed by high-temperature silica gel for partitioning the contact of the welding seam and subsurface water and extending the service life of the pipes.
Description
Technical field:
The utility model relates to the External compensator of pipe network compensator, particularly heat distribution pipe network.
Background technique:
External compensator is to be used with outer fixing joint or full fixed knot, be used to compensate the thermal walking of steel conduit, 30 to 40 meter amperes of generally being separated by are adorned an External compensator, employed in the market most of compensators as shown in Figure 1, only be bellows two ends suit ring flat-plates, there is following shortcoming in its structure: one, and outer pillar is in the thermal compensation campaign, two ends ring flat-plate and soil movement resistance increase, and have increased the stressed of outer fixing joint; They are two years old, the movable end of this structure does not have sealing, phreatic infiltration can be quickened the corrosion of pipe fitting, mud, the weld seam that sand enters the compensating action that pipe fitting inside directly has influence on bellows, particularly bellows and ring flat-plate is relatively weaker, in case go wrong, pipe fitting endangers the operation of whole pipe network with ineffective.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of External compensator is provided, and is rational in infrastructure, and function admirable is safe and reliable, long service life.
The technological scheme that the utility model is adopted for achieving the above object is: External compensator, comprise bellows and ring flat-plate, bellows links to each other with steel pipe, the bellows coating device has outer sleeve, the two ends ring flat-plate is connected with gusset, gusset is equipped with reducer pipe outward, and by dustproof felt seal, envelope has water-proofing material on the weld seam between bellows and the ring flat-plate between reducer pipe and the outer sleeve.
Described outer sleeve is the aluminum outer sleeve, and water-proofing material is a high-temperature silica gel.
The utility model two ends ring flat-plate is installed reducer, has avoided the ring flat-plate end face to contact with soil, has reduced the resistance to motion of pipeline and soil; The movable end area of contact increases, and adds multi-layer sealedly again, and silt is intercepted; Use the method for sacrificial anode and protective cathode, the aluminum outer sleeve is installed, effectively protect pipe fitting, simultaneously, on bellows and ring flat-plate weld seam, seal up high-temperature silica gel, cut off weld seam and contact, prolongation pipe fitting working life with phreatic.
Description of drawings:
Fig. 1 is traditional External compensator structural representation.
Fig. 2 the utility model structural representation.
Embodiment:
External compensator as shown in Figure 2, comprise bellows 5 and ring flat-plate 3, bellows links to each other with steel pipe 8, the bellows coating device has outer sleeve 4, the two ends ring flat-plate is connected with gusset 2, gusset is equipped with reducer pipe 1 outward, and by dustproof felt 6 sealings, envelope has the water-proofing material high-temperature silica gel on the weld seam between bellows and the ring flat-plate between reducer pipe and the outer sleeve.During installation External compensator is contained in outside the core pipe 7.
