Abstract
The utility model relates to a convenient pipe joint which is characterized in that a locking nut 1 is simultaneously sheathed on a joint sleeve base 3 and a steel pipe joint 7. Positioning screws 2 are distributed according to the circumference of a cross section and cause the locking nut to be fixed on the steel pipe joint 7. A taper pressing plate 4, a circular tightening ring 5, and a sealing rubber ring 6 are arranged in a hollow cavity formed by the locking nut 1, the joint sleeve base 3, and the steel pipe joint 7. The circular tightening ring 5 is positioned between the taper pressing plate 4 and the sealing rubber 6. The utility model has the advantages of simple structure, convenient assembly and disassembly, bi-directional 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 taper pipe 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 solves transverse sealing and longitudinal sealing problem with vertebra shape pressing plate and banding circle, simplifies with positioning screwn with locking nut to be connected orientation type; Thereby it is convenient to reach mounting or dismounting, prolongs pipeline working life, improves the purpose of reliability and Security.
Concrete scheme of the present utility model is: comprise locking nut, positioning screwn, joint block set, steel pipe joint, it is characterized in that: locking nut is sleeved in joint block set and the steel pipe joint simultaneously, and positioning screwn distributes by cross-sectional periphery locking nut is fixed in the steel pipe joint; In locking nut, joint block set, the formed cavity of steel pipe joint conical pressure plate, circular tighten ring, O-ring seal are housed, wherein the circular, hoop collar is between conical pressure plate and O-ring seal.
The utility model carries out transverse sealing by conical pressure plate 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.The utility model is sleeved in joint block set and the steel pipe joint simultaneously with locking nut, and distributing by cross-sectional periphery with positioning screwn is fixed on locking nut in the steel pipe joint again.This orientation type was both simple, and fixed effect is good again, and did 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, safe and reliable; Applied range can be used for pipe joint series tenders such as socket, union, elbow, threeway, four-way, pipe plug, the pipe width of cloth, 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 is made up of locking nut 1, positioning screwn 2, joint block set 3, conical pressure plate 4, circular, hoop collar 5, O-ring seal 6, steel pipe joint 7, its annexation and structure characteristic are: locking nut 1 is sleeved in joint block set 3 and the steel pipe joint 7 simultaneously, and positioning screwn 2 distributes by cross-sectional periphery locking nut 1 is fixed in the steel pipe joint 7; In locking nut 1, joint block set 3, steel pipe joint 7 formed cavitys conical pressure plate 4, circular tighten ring 5, O-ring seal 6 are housed, wherein circular, hoop collar 5 is between conical pressure plate 4 and O-ring seal 6.As can be seen from Figure 2: be distributed with four positioning screwns 2 on the cross-sectional periphery of locking nut 1, it is fixed on locking nut 1 in the steel pipe joint 7.
