Description
Technical field
The present invention relates to the structure of pipe connecting element ferrule fitting, specifically a kind of twolip single deck tape-recorder bell and spigot joint.
Background technology
Ferrule fitting is a kind of new pipe connecting element, and its structure type generally includes single deck tape-recorder nested structure and double card nested structure.Single deck tape-recorder bell and spigot joint is made up of joint body, cutting ferrule and several parts of clamp nut, its structure is relatively simple compared with double card nested structure, manufacture and easy for installation, cost is relatively low, but extruding is carried out with cutting ferrule pipe using an annular cutting edge of cutting ferrule front end during its use to contact, its sealing and load performance are restricted, in the use occasion that some pipeline pressures are high, sealing requirements are high, its connection reliability is difficult to ensure.
The content of the invention
The technical problems to be solved by the invention are to provide the strong twolip single deck tape-recorder bell and spigot joint of a kind of good airproof performance, bearing capacity.
The twolip single deck tape-recorder bell and spigot joint of the present invention is made up of joint body, cutting ferrule and clamp nut, and clamp nut front end is connected by internal thread and the external screw thread of joint body rear end, and cutting ferrule is pressed between the limited step on joint body and clamp nut；Cutting ferrule front end outer side is provided with the male cone (strobilus masculinus) being engaged with joint body endoporus rear end inner conical surface；The endoporus front end of cutting ferrule is provided with two adjacent annular grooves, so as to form the inner side cutting edge of twice annular.
Forward annular groove cross sectional shape is right angled triangle in the annular groove.
Annular groove cross sectional shape in the annular groove rearward is one section of circular arc.
Advantages of the present invention is embodied in：
1st, basic structure uses single deck tape-recorder nested structure, with respect to double card nested structure, and its simple in construction, cost is low, manufacture and easy for installation；
2nd, the structure utilizes twolip mouth structure, makes that during single deck tape-recorder bell and spigot joint use the dual-seal of similar double card bell and spigot joint can be formed in cutting ferrule front end, meanwhile, triple seal is formed in cutting ferrule rear end, thus obtain more preferably sealing effectiveness while structure is simplified.
3rd, by special multi-sealed, the sealing effectiveness with cutting ferrule pipe bound fraction is substantially increased, the ability for bearing internal pressure is also improved, thus can be used for the high pressure connection of fluid.
Brief description of the drawings
The vertical section structure schematic diagram of Fig. 1 present invention.
Embodiment
As shown in the figure, the twolip single deck tape-recorder bell and spigot joint is made up of joint body 1, cutting ferrule 2 and clamp nut 3, the front end of clamp nut 3 is connected by internal thread and the external screw thread of the rear end of joint body 1, and cutting ferrule 2 is pressed between the limited step 31 on joint body 1 and clamp nut 3；The front end outer side of cutting ferrule 2 is provided with the male cone (strobilus masculinus) 21 being engaged with the endoporus rear end inner conical surface 11 of joint body 1；The endoporus front end of cutting ferrule 2 is provided with two adjacent annular grooves 22, so as to form the inner side cutting edge 23 of twice annular.Forward annular groove cross sectional shape is right angled triangle in annular groove.Annular groove cross sectional shape in annular groove rearward is one section of circular arc.
As schemed, during the present embodiment use, first cutting ferrule 2 and clamp nut 3 are enclosed on the cutting ferrule pipe G to be connected, then cutting ferrule pipe front end is penetrated into joint body 1, joint body is connected with clamp nut and screwed, following design action is sequentially completed inside ferrule fitting：
1st, by the mechanically-propelled of clamp nut, cutting ferrule is pushed ahead；
2nd, joint body rear end passes through the inward-facing extruding cutting ferrule of inner cone；
3rd, cutting ferrule front end eliminates the fit tolerance of its internal diameter and card sleeve outer first；
4th, with the propulsion of cutting ferrule, first of its front end inner side cutting edge extrudes cutting ferrule pipe because of deformation first, is embedded in cutting ferrule pipe outer wall while cutting ferrule pipe inside necking deformation is made, forms first of sealing；
5th, with cutting ferrule continuation promote with, the contact surface of the conical surface and cutting ferrule male cone (strobilus masculinus) further increases in fittings body body, form the conical surface seal of outer ring, simultaneously bigger pressure makes cutting ferrule pipe produce bigger deformation, second inner side cutting edge of cutting ferrule is set further to be deformed inward simultaneously, embedded cutting ferrule pipe, forms second sealing.
6th, continue to screw in clamp nut, make slightly raised because of elastic deformation in the middle part of cutting ferrule, elastic stress makes to produce larger frictional force in cutting ferrule end face and clamp nut between limited step, prevent nut loosening, the elastic deformation of cutting ferrule can also absorb the vibration in hydraulic pipeline, meanwhile, cutting ferrule rear end is inwardly held cutting ferrule pipe tightly, form three seals.
Due to multi-sealed, the sealing effectiveness with cutting ferrule pipe bound fraction is improved, bearing capacity is strong.
