Description
Technical field
It the utility model is related to pipe connecting structure, more particularly to a kind of straight pin pipe connecting device.
Background technology
In the prior art, the connection method for fixed docking pipeline mainly has：Flange connection, welding, clamp connection
Connected with articulation.Articulation be it is a kind of can facilitate the conventional conduit coupling of installing/dismounting, but be the shortcomings that articulation：1
It is required that two fixed butt tube roads have higher axiality, 2 articulations do not apply to larger-diameter pipeline connection, and 3 live
Joint bonding strength is low, and 4 need to be threaded on connecting line, complex procedures.In-convenience in use, pacified using welding manner
Inner-walls of duct structure can be damaged during dress, and do not adapt to all pipeline connections and can not dismantle.Flange connection peace
Dress is complicated, it is necessary to which larger structure and installing space, dismounting are difficult.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple to installing, and can dismantle, applied widely, peace
The straight pin pipe connecting device that inner-walls of duct structure will not be damaged during dress.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of straight pin pipe connecting device,
Including shell, dead ring, tie down screw and sealing rubber ring；The shell is hollow tubular, and shell medial surface has raised block,
The cylindrical internal diameter for taper and less than shell of the dead ring, fastening ring diameter is corresponding with the external diameter of pipeline, in shell endoporus and
Dead ring opposite position is provided with internal thread, and the one end of dead ring in shell contacts with block, the tie down screw centre bore
Cylindrical corresponding with the dead ring, tie down screw is connected with outer casing screw, and tie down screw centre bore is cylindrical slotting with the dead ring
Connect, the sealing rubber ring is arranged in shell, forms the Hermetical connecting structure between shell and connecting tube.
As further improvement of the utility model, anti-skidding teeth can be set on dead ring medial surface.
The beneficial effects of the utility model are：The utility model includes shell and dead ring, and shell and dead ring correspond to position
Screw thread is installed, cylindrical dead ring is taper, and when tightening tie down screw, dead ring is extruded, so that dead ring compressing pipe
Road, complete the connection of pipeline.This mode of operation is simpler compared with the prior art, only need to use the common tools such as spanner, right
Operating personnel do not have technical ability limitation, are not take up excessive operating space, reduce the requirement to operating environment.
The utility model connects using the mode of dead ring compression pipeline, will not be to the internal structure of pipe wall
Damage, the corrosion-inhibiting coating such as inside pipeline.
The utility model need to only compress one end of the connection of pipeline, connected pipeline is not in connecting pipe
Need to rotate, the distance between pipeline can adjust according to field condition, more flexibility.
The utility model also has the advantages of having a wide range of application, isometrical, threeway, pipeline tapping branch, elbow, reducing and spray
Connection of head etc. can use this straight pin pipe connecting device.
The utility model will be further described with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Accompanying drawing 1 is the principle schematic that the utility model is acted on equal diameter pipe；
Accompanying drawing 2 is the principle schematic that the utility model is acted on tapered pipeline；
Accompanying drawing 3 is the principle schematic that the utility model is acted on three-way pipeline；
Accompanying drawing 4 is the principle schematic that the utility model is acted on elbow pipeline.
In accompanying drawing, 1 shell, 1-1 blocks, 2 sealing rubber rings, 3 dead rings, 4 pipelines, 4-1 tube walls, 5 locking screws
Bar.
Embodiment
Referring to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3 and accompanying drawing 4, a kind of straight pin pipe connecting device, including shell 1, dead ring
3rd, tie down screw 5 and sealing rubber ring 2；The shell 1 is hollow tubular, and the medial surface of shell 1 has raised block 1-1, described tight
Gu the cylindrical internal diameter for taper and less than shell 1 of ring 3, the diameter of dead ring 3 is corresponding with the external diameter of pipeline 4, in the endoporus of shell 1 and tightly
Gu the opposite position of ring 3 is provided with internal thread, the one end of dead ring 3 in shell 1 contacts with block 1-1, in the tie down screw 5
Heart hole and the dead ring 3 are cylindrical corresponding, and tie down screw 5 is threadedly coupled with shell 1, the centre bore of tie down screw 5 and the fastening
3 cylindrical grafting of ring, the sealing rubber ring 2 are arranged in shell 1, form the sealed connection knot between shell 1 and connecting tube 4
Structure.
During actual use, the straight pin pipe connecting device of suitable bore is selected, needs connected pipeline by two
Respective port be inserted into dead ring 3, then tighten tie down screw 5, during tightening, block 1-1 blocks dead ring
3, nut 5 extrudes dead ring 3, dead ring 3 is close on the tube wall 4-1 of pipeline 4, completes the connection of two pipelines, seals rubber
Cushion rubber 5 is blocked by tube wall 4-1, block 1-1 and shell 1, forms the region of sealing so that the utility model can prevent pipeline 4
Interior liquid oozes out.This mode of operation is simple and convenient, only need to use the common tools such as spanner, not have technical ability limit to operating personnel
System, is not take up excessive operating space, reduces the requirement to operating environment.Will not be to the internal structure of pipe wall during installation
Damage, the corrosion-inhibiting coating such as inside pipeline, and then extend use range of the present utility model.In view of connection two
The complicated state at scene during pipeline, the situation that distance between pipeline is not easy to adjust may be faced, and the utility model only needs two pipes
Road is inserted into device just, can adjust the distance of pipeline enclosure to a certain extent, more has flexibility during installation.Need what is illustrated
It is that the utility model can also be used on three-way pipeline, to state conveniently, accompanying drawing sentences two pipelines with this and is used as explanation.
To strengthen the locking degree of the utility model dead ring 3 and pipeline 4, teeth 3- is provided with the medial surface of dead ring 3
1。
