Abstract
The utility model relates to a steel flexible joint of an indoor cast iron drainage pipe system, which is mainly composed of pipelines, an anchor ear, sealing rings, a snap ring, etc., wherein the snap ring is arranged in a snap ring slot on the inner side of the anchor ear. The rubber sealing rings are respectively arranged between the snap ring and each of the two butt-joint pipelines. When the utility model is used and installed, the snap ring is fastened by a fastener in order to playing the functions of sealing and shock resistance. Compared with the prior art, the utility model has the advantages of convenient installation and maintenance, small joint size, beautiful appearance, corrosion resistance, good shakeproof performance, etc. The utility model is a novel steel flexible joint of a drainage pipeline system.
Description
The utility model belongs to a kind of technological improvement of construction drainage pipeline coupling member.
Known construction drainage pipeline, pipe fitting adopts spigot and socket type or flange to connect mostly, but these are all for being rigidly connected, and is unsuitable for high level, skyscraper and seismic region building and uses, easily deform and cause the damage of part or sanitary equipment, bayonet joint also exists many disadvantages in addition.1, pipeline connects easily dislocation, filler enter result in blockage in the pipeline or flowing water not smooth; 2, installation procedure complexity, operation inconvenience, the expense of taking a lot of work when keeping in repair material, and can only after system quits work, carry out destructiveness and repair; 3, be not suitable for mechanization production etc.At present, though some building has adopted the flange-type flexible interface, its radially amount of extracting and lateral displacement amount can't satisfy, and not quick detachable when pipeline overhauls, and efficient is also low during installation.
The utility model overcomes the deficiency of prior art existence and provides a kind of connection simple in structure convenient, and shock resistance is strong, the pipe coupling of the hard and soft property of clasp type aesthetic in appearance.
The utility model is to realize like this, the pipe coupling of the hard and soft property of clasp type is made up of pipeline, snap ring, anchor ear, seal ring etc., and anchor ear adopts cast iron or steel material to make cylindric, the inwall of anchor ear is provided with annular groove, is provided with the connecting hole that the snap ring two ends are installed with the corresponding surface of annular groove.Anchor ear is contained in the middle of the pipeline of two butt joints, and the rubber-like snap ring is housed in the annular groove, between snap ring and the pipeline rubber seal is housed, and the two ends of snap ring connect with fastening piece.Installation and maintenance are convenient in the flexible joint of mobilizable anchor ear of this employing and snap ring, when pipeline need overhaul or change, anchor ear and snap ring can be removed, and retube rapidly or pipe fitting, thereby have avoided rigidly connected in the past line rupture protection valve repairing.Have particular performances, and this joint volume is little, aesthetic in appearance, is convenient to indoor use, but compares economical with materials 20-30%, install and keep in repair work efficiency and improve 4-7 doubly with existing joint.
Between pipeline of the present utility model and the snap ring rubber seal is housed, can utilizes the elasticity of sealing material that pipeline is sealed, it is certain flexible that pipeline is possessed, and at pipeline axially and when radially being subjected to displacement, still can seal reliably, plays the effect of antidetonation.

Label declaration:
1, pipeline 2, fastening piece 3, shroud ring 4, rubber seal 5, snap ring 6, connecting hole 7, annular groove
With reference to the accompanying drawings present embodiment is done further enumeration, the pipe coupling of the hard and soft property of clasp type, by pipeline 1, snap ring 5, anchor ear 3, rubber seal 4 compositions such as grade, anchor ear 2 adopts cast iron or steel material to make cylindric, the inwall both sides of anchor ear 2 are provided with annular groove 7, be provided with the connecting hole that the snap ring two ends are installed with annular groove 7 corresponding surfaces, snap ring 5 uses rubber-like steel bar or steel disc to make, the two ends of snap ring 5 also are provided with the snap ring connecting hole, use when installing, snap ring 5 is packed into by connecting hole 6, and rubber seal 4 are contained in the centre that snap ring 3 docks with pipeline in the annular groove 7 of anchor ear 3, fastening the two ends of snap ring 3 then with fastening piece 2, can reach quakeproof and quake-resistant, the purpose of sealing.
The advantages such as the utility model compared with prior art has simple in structure, and it is convenient to connect, and anti-seismic performance is good, and is aesthetic in appearance are a kind of corrosion-resistant, watertight Novel steel flexible pipe joints.
Claims (2)
1, a kind of hard and soft property pipe coupling, comprise pipeline, rubber, seal ring, anchor ear etc., it is characterized in that anchor ear 3 is contained in the middle of the pipeline of two butt joints, in the annular groove 7 of anchor ear 3 inwalls rubber-like snap ring 5 is housed, between snap ring 5 and the pipeline 1 rubber seal 4 is housed, the two ends of snap ring 5 connect with fastening piece 2.
