Abstract
The utility model relates to a convenient pipe joint which is characterized in that a locking nut 1 is sheathed outside a steel pipe joint 6 and is connected with an external thread of a pipe joint body 3. The inner side of the locking nut 1 on the connecting part of the pipe joint body is in the shape of a ladder. An inclined plane of the locking nut is connected with a sealing ring 5 through a circular clamping ring 4. The sealing ring 5 is sheathed on the steel pipe joint 6. The utility model has the advantages of simple manufacturing technique, low cost, convenient assembly and disassembly, long service life, bidirectional sealing function, and high safety.
Description
The utility model relates to a kind of tube head connecting piece, especially makes things convenient for pipe joint.
As everyone knows, traditional pipeline connects the general conical tube internal thread that adopts and connects, and this Placement had both reduced the thickness at pipe coupling place, shortened pipeline working life, has reduced water again, with the Security of gas.In addition, this Placement mounting or dismounting are inconvenient, and labor intensity is big.Chinese patent discloses a kind of " New-type pipe joint ", though it has changed the pipe thread Placement, but because it is to be screwed in the screw of sleeve pipe by clamping screw, positioning screwn is screwed in attaching nut's the screw, is connected with the attaching nut with seal washer between the sleeve pipe or between sleeve pipe and curved head body or the three-way body, thereby this connection orientation type complexity, install still inconveniently, and it does not have clamping force, has only longitudinal sealing, do not have transverse sealing, so its sealing effect is not good enough.
The purpose of this utility model provides a kind of pipe joint that makes things convenient for, and is trapezoidal locking nut with O-ring seal, circular, hoop collar and a side internal diameter and solves transverse sealing and longitudinal sealing problem, simplifies with positioning screwn by locking nut to be connected orientation type; Thereby it is convenient to reach mounting or dismounting, and simplified manufacturing technique prolongs pipeline working life, improves the purpose of sealing effect.
Concrete scheme of the present utility model is: comprise that locking nut, positioning screwn, pipe connect body, steel pipe joint, is characterized in that: locking nut is sleeved on that steel pipe joint is outer to be connect this extracorporeal thread with pipe and be connected; The locking nut inboard that connects the body attachment portion with pipe is trapezoidal, and its inclined-plane is connected with O-ring seal through the circular, hoop collar, and O-ring seal is sleeved in the steel pipe joint.
The utility model carries out transverse sealing by locking nut and O-ring seal; Carry out longitudinal sealing by circular, hoop collar and O-ring seal; Therefore it possesses the two way sealed function, the good airproof performance of pipeline junction.Locking nut of the present utility model is sleeved on that steel pipe joint is outer to be connect this extracorporeal thread with pipe and be connected, and be fixed in the steel pipe joint with positioning screwn, but so both simplified structures is convenient to again install and remove again.Orientation type is simple simultaneously, and fixed effect is good again, and does not damage tube wall again.
Adopt such scheme, simple in structure, install and remove easy to maintenancely, have the two way sealed function, can prolong the working life of pipeline, manufacturing process is simple, and cost is low; Applied range can be used for pipe joint series tenders such as socket, union, elbow, threeway, four-way, pipe plug, pipe cap, gate valve, water nozzle, helps producing in batches.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the right elevation of Fig. 1.
By above-mentioned accompanying drawing as can be known: the utility model connects body 3, circular, hoop collar 4, O-ring seal 5, steel pipe joint 6 by locking nut 1, positioning screwn 2, pipe to be formed, and its annexation and structure characteristic are: locking nut 1 is sleeved on that steel pipe joint 6 is outer to be connect body 3 outside threads with pipe and be connected; Locking nut 1 inboard that connects body 3 attachment portions with pipe is trapezoidal, and its inclined-plane is connected with O-ring seal 5 through circular, hoop collar 4, and O-ring seal 5 is sleeved in the steel pipe joint 6.Positioning screwn 2 is fixed on locking nut 1 in the steel pipe joint 6.
