Abstract
The clip sleeve type pipe joint includes one hollow joint and one nut and the pipe is penetrated in the hollow part of the joint and the nut. Between the pipe and the joint and nut, there is clip sleeve, which has conic surface in the back end for fitting the nut and sealing ring in the front end, with the sealing ring being cut into two parts during the installation. The present invention has excellent sealing effect, high reliability and easy production and installation.
Description
Technical field
The invention belongs to engineering machinery field, employed Bite type fittings when specifically a kind of connection oil pipe and tracheae.
Background technique
In automobile, boats and ships and engineering mechanical device, there be being connected of many oil pipes and tracheae.Mostly adopt fittings body and a nut of a hollow, pipe is set in the middle vacancy of fittings body and nut, between pipe and fittings body, nut, also has a cutting ferrule, and there is tilted conical surface at the two ends of cutting ferrule.When screwing nut, the tilted conical surface at corresponding tilted conical surface extruding cutting ferrule two ends is arranged on fittings body and the nut, cutting ferrule is deformed, cutting ferrule tip side incision pipe plays effect fixing and sealing.The end face that is fastened in its front end of Bite type fittings has a tiny seal ring, and is very inconvenient during installation, if seal ring and cutting ferrule are made linking body structure, prior art can't solve the bonding problem of the end face and the seal ring of cutting ferrule in the production in enormous quantities.
Summary of the invention
The objective of the invention is problem, design a kind of Bite type fittings, solve and separate seal ring installation inconvenience and the jejune defective of disjunctor seal ring production technology at above-mentioned Bite type fittings existence.
The object of the present invention is achieved like this: Bite type fittings of the present invention comprises fittings body and nut of a hollow, pipe is set in the middle vacancy of fittings body and nut, between pipe and fittings body, nut, cutting ferrule is arranged, the rear end of cutting ferrule is the conical surface that matches with nut, a hollow of front end socket of cutting ferrule [the shape seal ring, above-mentioned hollow [the shape seal ring is after installing, and the seal ring slitting that is enclosed within cutting ferrule front end end face part and cylndrical surface part becomes two-part.
Bite type fittings of the present invention, because before installation, seal ring can be enclosed within the end face and the cylndrical surface of cutting ferrule front end, the installation of being convenient to joint connects, Bite type fittings after the installation, the seal ring slitting becomes two-part, and a part is at the end face of cutting ferrule front end, and another part is at the middle part of cutting ferrule, good seal action is played in the seal ring butt joint of front end, therefore, improved the reliability of sealing, convenient production and installation.
Description of drawings
Fig. 1 is the mounting structure schematic representation of Bite type fittings of the present invention.
Fig. 2 is the cutting ferrule of Bite type fittings of the present invention and the structural representation of seal ring.
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 comprises fittings body 1 and nut 5 of a hollow, pipe 2 is set in the middle vacancy of fittings body 1 and nut 5, on 5 on pipe 2 and fittings body 1, nut, cutting ferrule 4 is arranged, and the rear end of cutting ferrule 4 is the conical surfaces that match with nut 5, [the seal ring 3 of shape of a hollow of front end socket of cutting ferrule 4, above-mentioned hollow [shape seal ring 3 is after installing, and seal ring 3 slittings that are enclosed within cutting ferrule 4 front end end face parts and cylndrical surface part become two-part.
