Abstract
Disconnection-resisting pipe joint is one connecting part suitable for plastic pipe and metal hose and has connecting terminal with concave grooves and flanges for preventing disconnection and sealing. The disconnection resisting grooves have barbs and the sealing groove has smooth outer circular surface. The disconnection resisting groove and the sealing groove are set sectionally and the connecting terminal may be simplex, duplex or multiplex.
Description
What disconnection-resisting pipe joint of the present invention related to is a kind of plastic tube, flexible metal conduit connection pipe fitting of being applicable to.
Existing plastic tube connection pipe fitting body tongue and groove anti-tripping and impervious water do not add differentiation, mainly rely on the distortion of locking throat hoop compressing tube material and tube wall, are pressed into to connect among the body tongue and groove, and area of contact is big, compressive load per unit area is little, and the impervious water of anti-tripping is all undesirable.
The objective of the invention is deficiency at present plastic tube connection pipe fitting existence, a kind of disconnection-resisting pipe joint is provided, on the pipe fitting body, be respectively arranged with anti-tripping groove and seal groove, be pressed into respectively in anti-tripping groove and the seal groove when larynx hoop locking back connects tube wall deformation, not only seal but also have a good anti-tripping performance thereby reach between connection.
Disconnection-resisting pipe joint takes following scheme to realize: disconnection-resisting pipe joint has pipe fitting, on the pipe fitting joining end tongue and groove is arranged, and the tongue and groove on the joining end is respectively equipped with anti-tripping groove, seal groove; The anti-tripping groove is concavo-convex hangnail groove, can projection, groove be set on the hangnail face, is convenient to the pipeline anti-tripping and connects fastening.The seal groove convex portion has level and smooth outer peripheral surface, is convenient to connect with seal for pipe joints.Anti-tripping groove and seal groove can the space segmentation settings.
Disconnection-resisting pipe joint is owing to have anti-tripping groove, seal groove simultaneously at joining end; During use pipeline is sleeved on disconnection-resisting pipe joint and also puts the larynx hoop outward, pipe wall distortion and being pressed into respectively in anti-tripping groove and the seal groove behind the locking throat hoop, thereby make between connection the target that not only reaches sealing but also have good anti-tripping performance, larger-diameter connection pipe fitting anti-tripping groove and seal groove are provided with before and after dividing, adopt two locking throat hoops, the larynx hoop of front locking back compressing pipe wall is out of shape and tube wall is pressed in the anti-tripping groove after the need connecting pipe is sleeved on the disconnection-resisting pipe joint, and the pipeline to the locking throat hoop back behind the pipe-line system wriggling plays fixation, next one larynx hoop locking back compressing tube wall deformation enters among the seal groove, thereby reaches the purpose of sealing.Disconnection-resisting pipe joint is owing to have anti-tripping groove and a seal groove on same joining end, need connecting pipe through the larynx hoop compress connect after anti-tripping and good seal performance, connect solid and reliablely, line transportation gas, liquid can seepages.
The invention will be further described below with reference to accompanying drawing.
Fig. 1 is the disconnection-resisting pipe joint structural representation.
Has pipe fitting 1 with reference to the accompanying drawing disconnection-resisting pipe joint, on the pipe fitting connecting end, tongue and groove is arranged, tongue and groove on the joining end is respectively equipped with anti-tripping groove 2, seal groove 3, anti-tripping groove 2 is concavo-convex hangnail groove, projection 4, groove can be set on the hangnail face, locking throat hoop makes pipe wall distortion be pressed in the concavo-convex hangnail of anti-tripping groove 2 and clamp-ons projection 4 on the hangnail face when pipeline connects, and has improved the anti-tripping effect in the groove better.Seal groove 3 convex portions have level and smooth outer peripheral surface, connecting pipe inwall and seal groove convex portion close-coupled after the locking of larynx hoop, good sealing effect.。Anti-tripping groove 2 and seal groove can the space segmentation settings, can further improve the anti-tripping sealability.The disconnection-resisting pipe joint joining end front end bigger for diameter can be anti-tripping groove 2, the rear end is a seal groove 3, adopts 2 larynx hoops lockings during connecting pipe, and anti-tripping, sealability are better.Can space segmentation be provided with some groups for the less disconnection-resisting pipe joint anti-tripping groove 2 of diameter, seal groove 3.
The disconnection-resisting pipe joint joining end can be arranged to a kind of in single head, double end or the bull, so that connect different pipelines.The pipeline that adopts disconnection-resisting pipe joint to connect can be plastic tube, flexible metal conduit etc.Plastic tube is PEX pipe, plastic-aluminum pipe, PB pipe, PE pipe etc., and flexible metal conduit is copper pipe, aluminum pipe etc.
Claims (6)
1, a kind of disconnection-resisting pipe joint has pipe fitting, on the pipe fitting joining end tongue and groove is arranged, and it is characterized in that the tongue and groove on the joining end is respectively equipped with anti-tripping groove, seal groove.
2, disconnection-resisting pipe joint according to claim 1 is characterized in that the anti-tripping groove is concavo-convex hangnail groove.
3, disconnection-resisting pipe joint according to claim 1 and 2 is characterized in that anti-tripping groove hangnail face is provided with projection, groove.
4, disconnection-resisting pipe joint according to claim 1 is characterized in that the seal groove convex portion has level and smooth outer peripheral surface.
5, disconnection-resisting pipe joint according to claim 1 is characterized in that anti-tripping groove, the setting of seal groove space segmentation.
6, disconnection-resisting pipe joint according to claim 1 is characterized in that the disconnection-resisting pipe joint joining end can be arranged to a kind of in single head, double end, the bull.
