Abstract
Ferrule-type pipe fitting piecing devices, relate to field of engineering technology, the joint component using while belonging to especially a kind of oil pipe, tracheae connection.Have adapter piece (2), attaching nut (3) and cutting ferrule (1), pipe fitting (4) interts in adapter piece and attaching nut's middle vacancy, and cutting ferrule is sleeved on pipe fitting, and is positioned at adapter piece and attaching nut joint; Described cutting ferrule outward edge has tapering; On the longitudinal section of cutting ferrule, be provided with step (1-1).The utility model has improved sealing effect greatly, and it is simple in structure, be convenient to implement.
Description
Technical field
The utility model relates to field of engineering technology, the joint component using while belonging to especially a kind of oil pipe, tracheae connection.
Background technique
In field of engineering technology, the connection of the pipe fittings such as oil pipe, tracheae is ubiquitous.The Placement of oil pipe, tracheae, adapter piece, attaching nut and the cutting ferrule that uses hollow mostly, pipe fitting interts in adapter piece and attaching nut's middle vacancy, cutting ferrule is sleeved on pipe fitting, by adapter piece and attaching nut, closely cooperate, when attaching nut is tightened, make the cutting ferrule distortion that is squeezed, play effect fixing and sealing.Used cutting ferrule mostly is thin wall typed structure, easily produces fold, thereby produces gap, to such an extent as to affect sealing effect when being squeezed distortion.
Summary of the invention
The purpose of this utility model is to provide a kind of novel ferrule-type pipe fitting piecing devices, the object that improve structural design to reach, improves sealing effect.
Ferrule-type pipe fitting piecing devices provided by the utility model, is characterized in that, have adapter piece, attaching nut and cutting ferrule, and pipe fitting interts in adapter piece and attaching nut's middle vacancy, and cutting ferrule is sleeved on pipe fitting, and are positioned at adapter piece and attaching nut joint; Described cutting ferrule outward edge has tapering; On the longitudinal section of cutting ferrule, be provided with step.
The ferrule-type pipe fitting piecing devices that this use is novel provided, its cutting ferrule outward edge has certain taper, front end is thinner, can intert into a part in adapter piece with pipe fitting, produce certain distortion while being squeezed when attaching nut is tightened, cutting ferrule is provided with step simultaneously, when being squeezed distortion, can not produce fold, greatly improve sealing effect, and it is simple in structure, be convenient to implement.
Accompanying drawing explanation
Accompanying drawing partly discloses the utility model specific embodiment, wherein,
Fig. 1, the utility model structural representation;
Fig. 2, ferrule structure schematic diagram.
Embodiment
As shown in Figure 1, ferrule-type pipe fitting piecing devices provided by the utility model, have adapter piece 2, attaching nut 3 and cutting ferrule 1, and pipe fitting 4 interts in adapter piece and attaching nut's middle vacancy, cutting ferrule is sleeved on pipe fitting, and is positioned at adapter piece and attaching nut joint.
As shown in Figure 2, described cutting ferrule outward edge has tapering, and longitudinal section is provided with step 1-1.The angle of cutting ferrule outward edge and cutting ferrule inwall can be 10 °-15 °, take 12 ° as best.Cutting ferrule outward edge has tapering, front end wall thickness is thinner, can intert into a part in adapter piece with pipe fitting, while being squeezed when attaching nut is tightened, produce certain distortion, cutting ferrule is provided with step simultaneously, when being squeezed distortion, because there is certain deformation space at step place, so can not produce fold, avoid producing irregular gap, thereby improved sealing.
Claims (2)
1. ferrule-type pipe fitting piecing devices, it is characterized in that having adapter piece (2), attaching nut (3) and cutting ferrule (1), pipe fitting interts in adapter piece and attaching nut's middle vacancy, cutting ferrule is sleeved on pipe fitting, and is positioned at adapter piece and attaching nut joint; Described cutting ferrule outward edge has tapering; On the longitudinal section of cutting ferrule, be provided with step (1-1).
2. ferrule-type pipe fitting piecing devices according to claim 1, are further characterized in that, the angle of cutting ferrule outward edge and cutting ferrule inwall is 10 °-15 °.
