A kind of straight thread type pipeline snap joint
Technical field
Pipe joint is the utility model is related to, more specifically refers to a kind of straight thread type pipeline snap joint.
Background technology
Water supply and sewerage pipeline is the chief component of water supply and sewerage pipeline in water supply and sewage work, is conveying and distribution industrial water supply With Drinking Water and the main carriers of pipe (canal) road system of collection, conveying and discharge industrial wastewater, sanitary sewage and rainwater. Wherein, water supply network is the pipe-line system to user's water delivery and water distribution, is made up of pipeline, accessory and affiliated facility.Pipe material It common are metal tube and plastic tube.Accessory is mainly used for connecting pipe, reaches the annex of stringing purpose.Due to pipe material Difference, accessory is also different from the type of attachment of pipeline, and metallic conduit is connected through a screw thread.Plastic tube is then using the method for hot melt Connection.
Pipeline need to reconnect in comb or rupture, open circuit, leak to pipeline, typically can be first to metallic water pipe end Hank knotting is carried out respectively, and raw material band is wound on silking, is then attached using double end internal thread.Or simultaneously to plastic tube The outer wall in road and the inwall of joint for plastic tube carry out high warm and melted, and then joint for plastic tube is enclosed on plastic conduit, to be cooled Reach the purpose of fusion afterwards.Problems be present in the above method:
1st, there are certain technical requirements to metallic conduit hank knotting, it is necessary to which professional and technical personnel operates;
2nd, hank knotting or hot melt need specific purpose tool, while hot melt needs power supply;
3rd, hank knotting process time is longer, can bring many inconvenience to daily life and work.
Utility model content
The purpose of this utility model is to be directed to drawbacks described above, there is provided a kind of straight thread type pipeline snap joint, can reach and exempt from Hank knotting, exempt to heat, fast and effective connecting water pipe.
To achieve these goals, the utility model uses following technical scheme.
A kind of straight thread type pipeline snap joint, including cutting ferrule, locking nut, ring seal circle, attaching nut, cutting ferrule is in cone It is tubular, there is conical external screw thread, and several locking slots axially are provided with, the heavy caliber end of cutting ferrule is additionally provided with the circle that turns up;Locking nut Provided with conical internal thread and lock the small-caliber end in cutting ferrule;Attaching nut is provided with internal thread, is additionally provided with and blocks in one end The varus circle that circle matches that turns up of set, the small-caliber end of cutting ferrule pass through from attaching nut's other end, and by the circle that turns up with connecting The varus circle of connected nut offsets, and cutting ferrule of the ring seal circle pad in attaching nut, which turns up, encloses side.
Also include a connecting tube, connecting tube both ends are respectively equipped with the external screw thread to match with attaching nut.
The quantity of described locking slot is four be uniformly arranged.
In above-mentioned technical proposal of the present utility model, straight thread type pipeline snap joint of the present utility model has following several Individual advantage:
(1) it is reasonable in design, it is simple in construction, do not need professional practitioner just to operate during operation at the scene.
(2) specific purpose tool need not be used at work, it is only necessary to pipe joint is arranged on the pipe for needing to connect current On road, make the faster convenience of work.
(3) it is easy to operate and time-consuming short, reduce because cutting off the water to the trouble brought in daily life and work.
Brief description of the drawings

Fig. 2 is the decomposing schematic representation of snap joint of the present utility model;
Fig. 3 is the structural representation of the present utility model for being connected with the pipeline of threaded joint;
Fig. 4 is the connection procedure schematic diagram of the present utility model being used between two light pipes (before connection screw thread use);
Fig. 5 is the structural representation of the present utility model for being used between two light pipes connect.
Embodiment
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings.
Straight thread type pipeline snap joint of the present utility model is including cutting ferrule 1, locking nut 2, ring-like close as shown in Fig. 1~2 Seal 3, attaching nut 4.
Wherein, it is in cone shaped that cutting ferrule 1 is overall, and its caliber is adapted to the external diameter of connected pipe, and its one end is provided with the circle 5 that turns up, For being connected with attaching nut 4, attaching nut 4 is prevented to move, its pipe shaft is provided with conical external screw thread, and pipe shaft is provided with number on axial direction Bar locking slot 6 (general four are preferable), for shrinking the internal diameter of cutting ferrule 1 by locking nut 2, embrace and lock in connected pipeline On.The profile of locking nut 2 is hexagonal, and inner ring is conical internal thread, for being adapted to the tapered thread of cutting ferrule 1, reaches cutting ferrule 1 The purpose of lock is embraced with pipeline.The profile of locking nut 2 is hexagonal, and provided with internal thread, the circle that turns up with cutting ferrule 1 is additionally provided with one end The 5 varus circles 7 to match, the small-caliber end of cutting ferrule 1 pass through from the other end of attaching nut 4, and pass through circle 5 and the attaching nut of turning up 4 varus circle 7 offsets.The pad of ring seal circle 3 be rubber or nylon material, and external diameter turns up with the upper end of cutting ferrule 1 to be enclosed 5 diameters and be adapted to, The connecting tube or nipple that the circle that turns up for sealing after compression and cutting ferrule 1 offsets.
, only need to be first by card when needing light pipe 7 with the pipeline (three-way pipe 8 as shown in Figure 3) of threaded joint being connected Set 1 is socketed on light pipe 7, then cutting ferrule 1 is passed back through from attaching nut 4 together with light pipe 7 so that the circle 5 that turns up of cutting ferrule 1 Hook and support with the phase of varus circle 7 of attaching nut 4, locking nut 2 is then locked into cutting ferrule 1 and light pipe 7, then again in attaching nut 4 Attaching nut 4, is finally tightened on the nipple of three-way pipe 8, to realize rapid abutting joint by interior setting ring seal circle 3.
Incorporated by reference to shown in Fig. 4~5, when needing to be docked two light pipes 7, it is also necessary to arrange a connecting tube 9, connecting tube 9 both ends are respectively equipped with the external screw thread to match with attaching nut 4, so in the both sides of connecting tube 9 respectively using a set of as shown in Figure 1 Snap joint, two light pipes 7 are connected on the external screw thread at the both ends of connecting tube 9 respectively using with Fig. 3 identicals mode. During the use, the effect of cutting ferrule 1 is one fixing point of formation on pipeline, so as to the nut 4 that is rotatably connected, makes connecting tube 9 There is an opposite power, so as to reach the purpose of sealed connection.
In summary, the formula Quick joinker for pipeline of cutting ferrule 1 of the present utility model, can effectively realize between water pipe quick connects Connect, use occasion is extensive, and exempts from hank knotting, exempts to heat, very convenient, is worthy of promotion and application.
Those of ordinary skill in the art is it should be appreciated that the embodiment of the above is intended merely to illustrate that this practicality is new Type, and be not used as to restriction of the present utility model, as long as in spirit of the present utility model, to described above Change, the modification of embodiment will all fall in Claims scope of the present utility model.
