Abstract
The invention discloses a ferrule-type pipe joint which comprises a hollow fitting body and a connecting nut. The fitting body and the connecting nut are provided with a conical surface respectively. A tube goes through and is positioned at the hollow part of the fitting body and the connecting nut. A socket is also arranged between the tube and the fitting body as well as the connecting nut. The angle of the external conical surface at the rear end of the socket is smaller than the angle of the conical surface of the connecting nut. A cutting edge is arranged near the rear end of the socket, a taper hole is arranged on the rear end of the fitting body and a cuniform sealing ring is arranged on the end face of the front end of the socket. The ferrule-type pipe joint realizes the purposes of sealing and separating of a single ferrule-type pipe joint by using the rigid connection of the socket and the sealing of the taper hole on the fitting body and the cuniform sealing ring, thus being characterized by being capable of being dismounted for a plurality of times.
Description
Technical field
The invention belongs to engineering machinery field, employed Bite type fittings when being specifically related to a kind of connection oil pipe and tracheae pipeline.
Background technique
In automobile, boats and ships and engineering mechanical device, there be being connected of many oil pipes and tracheae.Adopt fittings body and a nut of a hollow mostly, pipe is set in the middle vacancy of fittings body and nut, between pipe and fittings body, nut, also has cutting ferrule, when utilizing nut and fittings body to screw to the extruding force of cutting ferrule, cutting ferrule is deformed, and cutting ferrule tip side incision pipe plays effect fixing and sealing.Existing structure mainly contains single deck tape-recorder nested structure and two FERRULETYPE structures: the cutting ferrule of single deck tape-recorder nested structure will play sealing and the effect that is connected simultaneously, obtain better sealing and be connected effect, will allow cutting ferrule cut deeply more to pipe, butt joint body cone and attaching nut's conical surface damage big more, cut to such an extent that deep more actinal surface degree of depth conformity is poor more, also just poor more to the sealing of repeated disassembled and assembled; In two cutting ferrule pipe joints, seal and be connected this paradox and effectively separated, two effects that cutting ferrules play sealing respectively and link, but manufacture cost is big.
Summary of the invention
The mixing that the objective of the invention is the to solve present single deck tape-recorder shell type pipe joint existing problem that is tightly connected, design a kind of sealing and be connected thoroughly separate, sealing is reliable, the Bite type fittings that can repeatedly dismantle.
The object of the present invention is achieved like this: Bite type fittings of the present invention, it comprises fittings body, the attaching nut of hollow, the conical surface is arranged in the attaching nut, pipe is set in vacancy among fittings body and the attaching nut, between pipe and fittings body, attaching nut, also has a cutting ferrule, the rear end male cone (strobilus masculinus) angle of cutting ferrule is less than the angle of attaching nut's conical surface, one cutting edge is arranged near the rear end of cutting ferrule, it is characterized in that on the fittings body rear end taper hole being arranged, cutting ferrule front end end face is provided with the wedge-type seal circle, and above-mentioned seal ring and cutting ferrule also can be overall structures.
Above-mentioned Bite type fittings, when screwing up with a wrench the attaching nut, the distortion of cutting ferrule rear end male cone (strobilus masculinus), radial contraction is slowly firmly grasped to pipe, it is big that angle becomes, cutting edge incision pipe when cutting ferrule rear end male cone (strobilus masculinus) is consistent with attaching nut's conical surface, has been finished linkage function, and this moment, the cutting ferrule front-end face also held out against the end face of fittings body taper hole, the wedge-type seal circle has also been blocked the fittings body taper hole, thereby has realized single deck tape-recorder sleeve joint sealing and be connected the purpose of separating, and has the advantages that repeatedly to dismantle.
Description of drawings
Fig. 1 is the mounting structure schematic representation of Bite type fittings of the present invention.
Fig. 2 is the local enlarged diagram of Bite type fittings of the present invention.
Embodiment
The invention will be further described by embodiment below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, Bite type fittings of the present invention, it comprises fittings body 1, the attaching nut 2 of hollow, in the attaching nut 2 conical surface is arranged, pipe 5 is set in vacancy among fittings body 1 and the attaching nut 2, also has a cutting ferrule 4 at pipe 5 and fittings body 1,2 of attaching nuts, the rear end male cone (strobilus masculinus) angle of cutting ferrule 4 is less than the angle of attaching nut's 2 conical surfaces, one cutting edge is arranged near the rear end of cutting ferrule 2, and fittings body has taper hole on 1 rear end, is provided with wedge-type seal circle 3 at cutting ferrule 4 front end end faces.
