Abstract
The utility model relates to a steel double rubber ring flexible interface for a water pipe. The steel double rubber ring flexible interface comprises a faucet steel ring provided with a rubber ring groove, and a sealing rubber ring and a bell mouth steel ring arranged in the rubber ring groove, and is characterized in that the faucet length of the faucet steel ring and the bell mouth depth of the bell mouth steel ring are 165-200 millimeters respectively. The steel double rubber ring flexible interface has the beneficial effects that an improved steel double rubber ring flexible interface is taken as a water pipe interface, so that the defect of insufficient relative rotation angle of the interface can be overcome for a tubular product, the relatively allowed rotation angle of the interface is increased to 0.5-2 degrees, the adaptability to poor geological condition areas such as non-uniform foundations, soft soil areas, high-earthquake-intensity areas and coastal areas is increased greatly, the characteristics of convenience and rapidness for installing the interface are kept simultaneously, the safety and reliability of a pipeline are enhanced, and the pipeline maintenance cost is reduced.
Description
Technical field
The utility model belongs to water delivery tubing, relates in particular to the two cushion rubber flexible interfaces of steel that a kind of conduit pipe is used.
Background technique
Conduit pipe is widely used in industries such as municipal plumbing, industrial plumbing, agricultural and water conservancy waterline, electric power water delivery, intercity and basin water transfer.Conduit pipe mainly comprises tubing such as Prestressed concrete cylinder pipe, band cylinder reinforced concrete pipe with steel.This kind tubing have bear press in high, dark earthing, characteristics such as impermeability is strong.It has flexible interface, that is, the two cushion rubber flexible interfaces of steel are prefabricated respectively in the conduit pipe two-port, and two conduit pipes are pegged graft through the two cushion rubber flexible interfaces of steel, can adapt to the variation of the landform migration of foundation settlement and even earthquake.Domestic at present " Prestressed concrete cylinder pipe " (GB/T19685-2005), (JC/T1091-2008) to the professional technique standard of the two cushion rubber flexible interface aqueducts of this type of steel, and it is that 0.5 ° of tubing and interface schematic representation see Fig. 3 for details that the tubing interface of manufacturing allows relative rotation.Flexible interface be applied in bearing capacity better, on the pipe, each item technical order all can engineering demands uniformly for ground.If but pipe laying is in unfavorable geological conditions such as inhomogeneous ground, weak soil, high earthquake intensity district, coastal region area; Flexible interface only possesses 0.5 degree corner can not satisfy actual demand; The excessive sedimentation or the displacement of ground may cause destructive accidents such as interface tube leaks, extracts; Improve the pipeline safety operation risk, be unfavorable for engineering construction and management.
(the patent No.: 201020574365.2) disclose a kind of pair of cushion rubber Prestressed concrete cylinder pipe, formed by socket steel ring that has aprons slot and bellmouth steel loop; Shorten the outer adverse slope length 10mm of bellmouth steel loop; The face length of bellmouth steel loop increases 10mm; The outer adverse slope angle of bellmouth steel loop is increased to 32 °.This patent is to pull edge lengths through reducing bellmouth, increases to pull the technological scheme that the limit angle beta increases mouth of pipe permission corner.There is following shortcoming in it: since bellmouth to pull the limit angle beta excessive, can cause piping erection difficulty and O-ring seal spoilage too high, increased project installation difficulty and operating expenses.
Demand developing the two cushion rubber flexible interfaces of steel of improvement aqueduct in the industry urgently,, can satisfy engineering actual requirement quick and easy for installation again to reach the relative rotation ability that can effectively improve the tubing interface.
The model utility content
The utility model is in order to overcome deficiency of the prior art; The two cushion rubber flexible interfaces of the steel that provides a kind of conduit pipe to use; Through the slot length of change socket steel ring and the bellmouth degree of depth of bellmouth steel ring; Can strengthen the aqueduct interface and allow corner relatively, can effectively improve the corner adaptive capacity of tubing interface, can satisfy engineering actual requirement quick and easy for installation again to inhomogeneous ground, weak soil and high earthquake intensity district unfavorable geological condition area.
The utility model is for realizing above-mentioned purpose; Realize through following technological scheme; The two cushion rubber flexible interfaces of the steel that a kind of conduit pipe is used; Comprise the socket steel ring that has aprons slot and the O-ring seal and the bellmouth steel ring that place in the aprons slot, it is characterized in that: the bellmouth degree of depth of the slot length of said socket steel ring and bellmouth steel ring is respectively 165-200mm.
The interface relative rotation allowed band of said conduit pipe is 0.5 °～2 °.
Beneficial effect: through the two cushion rubber flexible interface conduit pipe interfaces of the steel of improvement; Make tubing can overcome the not enough shortcoming of interface relative rotation; Interface allows corner to increase to 0.5 °-2 ° relatively, and the adaptive capacity in unfavorable geological conditions such as inhomogeneous ground, Soft Soil Area, high earthquake intensity district, coastal region area improves greatly, has kept interface characteristics quick and easy for installation simultaneously; Improve the safety reliability of pipeline, reduced the pipeline maintenance cost.

Embodiment
Below in conjunction with preferred embodiment; Details are as follows to the embodiment that provides according to the utility model: see accompanying drawing 1-2 for details; The two cushion rubber flexible interfaces of the steel that a kind of conduit pipe is used; Comprise the socket steel ring that has aprons slot and the O-ring seal 3 and the bellmouth steel ring 2 that place in the aprons slot, the bellmouth degree of depth of the slot length of said socket steel ring 1 and bellmouth steel ring is respectively 165-200mm.The interface relative rotation allowed band of said conduit pipe 4 is 0.5 °～2 °.
Embodiment
See Fig. 1 for details, the conduit pipe interface carries out the tubing manufacturing according to technical parameter, and guarantee the interface size: a, b, c, d, β are controlled in the scope.Wherein: socket steel ring aprons slot size should meet " the Prestressed concrete cylinder pipe joint is used shaped steel " (JC/T1091-2008) standard-required.O-ring seal adopts tolerance of size and performance to meet the cushion rubber of " prestressing force and from the effective rubber seal of stress reinforced concrete " (JC/T 748-1987 (1996)) standard.Gap d between interface bellmouth working surface and the socket working surface is controlled between 0.2mm～1.0mm, and size c is consistent with the product manufacturer's standard with angle beta.The bellmouth degree of depth of the slot length of socket steel ring 1 and bellmouth steel ring can be adjusted its slot length or the bellmouth degree of depth according to tubing caliber size, is 1M like the tubing caliber, and slot length is 165mm, and the bellmouth degree of depth is 170mm; The tubing caliber is 2M, and slot length is 180mm, and the bellmouth degree of depth is 200mm.
During use, after tubing was installed, two O-ring seals of configuration inserted bellmouth to designed depth with socket, and carry out the joint hydrostatic test in the socket steel ring slot, promptly accomplished tubing and installed.It is 0.5 °～2 ° that tubing butt joint rear port allows angle range relatively, to adapt to unfavorable geological condition area demands such as inhomogeneous ground, Soft Soil Area, high earthquake intensity district, coastal region.
