Abstract
A multiple sealing component for remedy of cast-iron pipe leakage comprises a pair of fastened sealing casings 5. A left sealing ring 2 with saw-tooth shaped cross-section is positioned in the groove of the left side of the sealing casings, while a right sealing ring 9 with lip shaped cross-section is positioned in the groove of the right side, and the sealing rings 2 and 9 have only a miter joint 7 which is stagger with the faying surface of the sealing casings. A sealing strip 3 with concavo-convex shaped cross-section is arranged between the conjunction planes of the pair of sealing casings which are jointed tightly with a bolt group 6 through screws in the conjunction planes. The utility model can be used without disassembling pipes, and has strong adaptability and good sealing property. Once the sealing ring between bell-and-socket joints of the existing cast-iron pipes has failure or the pipe body leaks because of cast defect, the sealing component can be installed for remedy, which is simple, practicable, reliable and convenient.
Description
The utility model relates to the sealing technique that a kind of water pipe leaks and remedies.
Cast iron tube is the tap water supply pipeline that the most generally use in the current whole world.Its spigot and socket type is installed very convenient, but because its seal ring lost efficacy or casting defect causes pipe leakage to be difficult to maintenance.As changing seal ring, just need 3 every long pipe of 6 meters of dismounting; As to repair the aperture that leaks on the body be unusual difficulty, generally needs to change pipeline.Dismantle bigger pipeline and need use crane gear, therefore the workload of dismounting and replacing pipeline and all very big the destruction on ground.
The purpose of this utility model be exactly to provide a kind of do not need to dismantle pipeline, simple, adaptability strong, good airproof performance, the cast iron tube that can be fastened on the leaking pipe outside leak and remedy multi-sealed.
The technical solution of the utility model is achieved in that a kind of cast iron tube leaks and remedies multi-sealed, be characterized in: it is made up of the seal casinghousing 5 of a pair of fastening, being equipped with the cross section in the two-port groove of the left and right sides of seal casinghousing respectively is the left and right seal ring 2,9 of sawtooth and lip, seal ring 2,9 have only one with this diagonal joint 7 that seal casinghousing junction plane is staggered, being equipped with the cross section between this conjunction plane to seal casinghousing is cancavo-convex Stamping Steel Ribbon 3, and bolt group 6 is linked together this to seal casinghousing tightly by the screw on the conjunction plane.
Because the utility model is the seal fitting that a cover is fastened on the leaking pipe outside, realize that so do not need to dismantle pipeline, workload is very little to the sealing at the place that leaks; The multi-sealing structure that the utility model adopts has very high adaptability to the roughness of casting surface and the error of outer diameter tube, and sealability is fine.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a schematic appearance of the present utility model.
Fig. 2 is a side diagrammatic sketch of the present utility model.
Fig. 3 is the A-A cut-away view of Fig. 2.
Fig. 4 makes whole seal ring and Stamping Steel Ribbon.
Fig. 5 is Stamping Steel Ribbon and sectional view is installed.
Among the figure 1, seal ring 5, capsul spare 6, attachment bolt 7, joint 8, stiffening rib 9, the right seal ring that may lose efficacy in the cast iron tube 2 installed of socket joint, left seal ring 3, Stamping Steel Ribbon 4, pipeline
This Sealing is made up of the capsul spare 5 of a pair of fastening, bolt group 6 is linked together this to seal casinghousing tightly by the screw on the junction surface, in the two-port groove of the left and right sides of seal casinghousing 5, be equipped with a left side respectively, right seal ring 2,9, just can be in order not dismantle pipeline with a left side, right seal ring 2,9 are sleeved on pipeline 1 outer wall, seal ring between seal casinghousing 5 and pipeline 1 must disconnect again and connecting, seal ring of the present utility model has only a diagonal joint 7 of staggering with two seal casinghousing junction planes, and adopt sawtooth and lip cross section, between the conjunction plane of two seal casinghousings 5, be equipped with the Stamping Steel Ribbon 3 that is designed to the concave-convex shape cross section, so the error of Cast Iron Surface roughness and outer diameter tube is had very big adaptability.On the connecting flange of seal casinghousing 5, be provided with stiffening rib 8, improved the intensity of flange.
Leak because of casting defect on seal ring 4 inefficacy in a single day between cast iron tube 1 joint that existing socket joint is installed or the body, can remedy as long as install this Sealing additional, simple, reliable convenient.
