Abstract
A quick loading and unloading joint of pipe comprises a pipe fitting and a tube, characterized in that the pipe fitting, equipped with the external thread, fits the tube and has one end plane to be touched with one end plane at the thread port of pipe fitting, wherein around the external circumference a seal rubber bushing is wrapped. The thread port of pipe fitting has an inside diameter same as that of the tube and an outside diameter more than that of the tube. A connection nut is equipped with one lateral end being an female thread section fitting the external thread of the pipe fitting and the other lateral end being an inside cone capable of expressing a pressure on the seal rubber bushing. The utility model integrates the advantages of a quick connection of pipe fitting, a quick join and a flexible connection and is characterized by convenient operation, reliable and complete function.
Description
Technical field:
The utility model relates to pipe fitting, a kind of pipeline tieing of more specifically saying so.
Background technique:
Pipeline adopts screwed connection usually.During installation, pipe need be opened silk, for guaranteeing the sealability between pipe and tieing, and be in screw thread with a large amount of adhesive tapes.During maintenance, pipe fitting can not directly be dismantled, thereby brings a lot of inconvenience.
Existing slip-knot has solved this problem to a certain extent, but it often need with the supporting use of this pipe fitting of outer silk, pipe still will be opened silk, and the cost height, most pipe fittings also can only be dismantled indirectly, can't satisfy maintenance requirement.
Fast knot has changed traditional method with screwed connection, do not open silk and just can connect pipe fast, but fast knot only is used in two connections between straight tube by limitation.
Quickly jointed tubular workpieces is tieing, pipe, combine soon, finished by the various tieing that are connected to fast between two straight tubes to be connected with the quick of pipe way, brings very big facility to pipe laying.But quickly jointed tubular workpieces is not drawn the easy-to-dismount advantage of slip-knot, and himself structure exists deficiency: when quickly jointed tubular workpieces was connected with pipe, pipe was inserted within the elbow, a fatal shortcoming of this product when this is the dismounting pipe fitting.Because, under various occasions, cooperating between pipeline and elbow etc. and the body of wall is very compact, and, pipeline usually is to be fixed on a certain position by pipe clamp, therefore, pipeline and elbow do not have a bit move place each other, so, owing to there is the pipeline section that is inserted in the elbow, even if back out the attaching nut fast, also because of the no room to swing a cat pipe that can't make separates with elbow, the same difficulty that exists in the dismounting.
Summary of the invention:
Technical problem to be solved in the utility model is to avoid existing problem in the above-mentioned prior art, and a kind of quickly jointed tubular workpieces, knot and the advantage of slip-knot soon, easy to use, multiple functional quick loading and unloading pipeline tieing of having concurrently is provided.
The technological scheme that the utility model technical solution problem is adopted is:
The utility model comprises pipe fitting and tubing.
Structural feature of the present utility model is, matches with tubing with the pipe fitting that has outer silk, and the internal diameter of pipe fitting silk mouth is identical with pipe internal diameter, and the external diameter of pipe fitting silk mouth is greater than tube outer diameter, tube end face and pipe fitting silk
The mouth end face offsets, and the periphery in the tubing end is with seal rubber sleeve; The attaching nut is set, described attaching nut's one distolateral internal thread segment for matching with the outer silk of pipe fitting, another is distolateral for forming the inner conical surface of pressure to seal rubber sleeve.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model is when implementing to be connected with pipe fitting to tubing, tubing is directly to support to the end face of pipe fitting with its port, therefore, as long as the attaching nut is backed off from pipe fitting silk mouth, tubing promptly separates with pipe fitting, do not need in the axial direction tubing or pipe fitting to be moved, this makes installation and maintenance process simplify greatly, and the dismounting pipe fitting is very convenient, and such tieing both can be used as bend pipe tools, the function that has replaced slip-knot and outer silk again is with a generation three.
2, the seal rubber sleeve in the utility model adopts the lengthening design, and the periphery at pipe fitting end face and tubing forms sealing respectively, not only be convenient to dismounting, and sealability is better.
Accompanying drawing is the utility model structural representation.
Embodiment:
In the present embodiment, tieing is connected with tubing with the form of elbow.
As shown in FIG., match with tubing 2 with the pipe fitting 1 that has outer silk, the internal diameter of the silk mouth of pipe fitting 1 is identical with the internal diameter of tubing 2, and the silk mouthful external diameter of pipe fitting 1 is greater than the external diameter of tubing 2, the silk mouthful end face of the end face of tubing 2 and pipe fitting 1 offsets, and the periphery in tubing 2 ends is with seal rubber sleeve 3; Attaching nut 4 is set, attaching nut's 4 one distolateral internal thread segment for matching with the outer silk of pipe fitting 1, another is distolateral to be the inner conical surface that can form pressure to seal rubber sleeve 3.In order to guarantee its sealability, seal rubber sleeve 3 should adopt the lengthening design, and its length utilizes the elasticity of gum cover to form pressure suitably greater than the length of attaching nut's interior tapered cavity.When it was in working state, an end end face and pipe fitting silk mouth end face offseted, and elongated portion is compressed, and makes it become the taper that matches with attaching nut's inner chamber, and seal rubber sleeve forms sealing in the periphery of pipe fitting end face and tubing respectively.
In concrete the enforcement, should be at the outside dimension of outer installment positioning tab 5 positioning tabs 5 of pipe fitting 1 greater than the external diameter of attaching nut's 4 corner angle.When implementing to install, can make elbow near wall, both guarantee the steadiness of pipeline, be convenient to attaching nut 4 dismounting again by this positioning tab 5.
Connection procedure is: at first bend pipe tools 1 is connected with nut 4 by its outside screw thread, along with tightening of nut 4, its inner conical surface forms respectively along the tubing pressure on the both direction axially and radially seal rubber sleeve 3 is main, on the one hand pipe fitting and tubing are implemented to be connected, make seal rubber sleeve 3 form sealing in the periphery of pipe fitting end face and tubing respectively on the other hand.Unloading process is opposite.
Claims (2)
1, quick loading and unloading pipeline tieing, comprise pipe fitting (1) and tubing (2), it is characterized in that, match with tubing (2) with the pipe fitting (1) that has outer silk, its mouth internal diameter of pipe fitting (1) is identical with the internal diameter of tubing (2), the external diameter of its mouth of pipe fitting (1) is greater than the external diameter of tubing (2), and the silk mouthful end face of the end face of tubing (2) and pipe fitting (1) offsets, and the periphery in tubing (2) end is with seal rubber sleeve (3); Attaching nut (4) is set, described attaching nut's (4) one distolateral internal thread segment for matching with the outer silk of pipe fitting (1), another is distolateral to be the inner conical surface that can form pressure to seal rubber sleeve (3).
