Description
Technical field
This utility model relates to a kind of straight thread type pipeline connector being applied to pipeline connection.
Background technology
Straight thread type pipeline connector is a kind of extensive application strength member on fluid line connects, existing
Some straight thread type pipeline connectors are generally hard to be sealed, including the joint body being connected with pipeline, cutting ferrule with
And nut.Utilizing the conical surface to coordinate between cutting ferrule with joint body, nut is for compressing cutting ferrule.
While compression, the inner edge inside cutting ferrule thrusts pipeline outer wall and forms effectively sealing.This seals firmly to pipe
The size in road itself and material require the highest, the most undesirable, just do not reach the purpose of sealing.
Even if after having sealed, pipeline also can leave scar, use for secondary and cause difficulty.It addition, it is existing
The hard sealing means having must can be only achieved the purpose of sealing by instrument after tightening, uses the most relatively
For inconvenience.
Utility model content
In view of this, this utility model provides the straight thread type pipeline connector that a kind of soft and hard seal combines, profit
The purpose sealed is reached with soft and hard seal, low to requirements for pipes, and only rely on free-hand tightening and just can reach
To the purpose sealed.
For solving above technical problem, the technical solution of the utility model is: a kind of soft and hard seal combines
Straight thread type pipeline connector, including the joint body for being connected with pipeline, for the cutting ferrule that seals with
And for compressing the nut of cutting ferrule；It is provided with, on described joint body and nut, the screw thread cooperated；
Described joint body inner chamber has step, and this step and pipeline outer wall piece together and accommodate O-ring seals
Cavity；Described cutting ferrule forward ends thereof O-ring seals, rear end is pre-large post-small tapered sleeve；Also include one
Individual rotary head, described rotary head is provided with and the conical surface of cutting ferrule rear end fitted seal；Described nut passes through rotary head
Cutting ferrule is compressed.
Improving as one, described joint body rear end is provided with the conical surface；Described cutting ferrule front end is provided with
Step so that cutting ferrule front end can extend into cannelure and contact with O-ring seals, and makes on step
Corners and joint body on taper-face contact.By offering step in cutting ferrule front end so that cutting ferrule
Front end easily extends into cannelure and extrudes O-ring seals so that it is deformation reaches relatively reliable
Sealing effectiveness；Secondly, the taper-face contact of the wedge angle on step and joint body rear end, extruding time
Waiting, wedge angle produces slight deformation, fills the gap between wedge angle and the conical surface, also plays the mesh of sealing
's.
Preferred as one, the conical surface on described joint body rear end is 40 °-50 °.40°-50°
The conical surface and the wedge angle cooperation of 90 ° so that when cutting ferrule is extruded rear axially-movable, wedge angle connects with the conical surface
Synapsis by axially and radially make a concerted effort, and axial force and radial force equal in magnitude.So be conducive to power
Distribution, be more prone to realize sealing effectiveness.
Improving as one, described rotary head is provided with and the conical surface of cutting ferrule rear end fitted seal.At cutting ferrule
And arranging a rotary head between nut, this rotary head is provided with the conical surface that the tapered sleeve with cutting ferrule rear end coordinates,
Extruding when, also can form sealing surface, reach better seal effect.By rotary head and cutting ferrule
Cooperatively form sealing surface, relatively directly utilize compared with nut cooperatively forms sealing surface with tapered sleeve, its difficult processing
Road is less, it is not necessary to nut is carried out special handling.
Improve as one, be provided with, inside described rotary head rear end and nut, the conical surface or arc cooperated
Face.Being coordinated by the conical surface or cambered surface makes the two combine more closely, is more prone to stress and is difficult to pine
Dynamic.
Preferred as one, the tapering of described cutting ferrule is 20 °-30 °.
Preferred as one, described O-ring seals is that silica gel makes.Silica gel rebound performance is good, chemistry
Stable in properties, the most perishable.
Preferred as one, the string diameter of described O-ring seals more than cannelure sidewall and pipeline outer wall it
Between spacing.After O-ring seals is filled into cannelure, it is not necessary to cutting ferrule extruding just can produce certain journey
The deformation of degree, reaches certain sealing effectiveness.Such that the extruding force making later stage cutting ferrule provide is inadequate,
Or after O-ring seals fatigue, still can seal.
The straight thread type pipeline connector with said structure that has the beneficial effect that of the present utility model, uses
The form that soft and hard seal combines carries out multi-stage sealed.Owing to soft seal deformation is big so that this joint is to pipe
The requirement of road size and Facing material is substantially reduced.Simultaneously because the hard existence sealed so that whole
It is greatly improved again for the soft seal that the reliability of joint is more simple.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Labelling in figure: 1 nut, 2 pipelines, 3 joint bodies, 4 O-ring seals, 5 cutting ferrules, 6 turns
Head, 7 ground floors seal firmly, 8 second layers seal firmly.
Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model, knot below
The utility model is described in further detail to close detailed description of the invention.
As it is shown in figure 1, this utility model includes, for the joint body 3 being connected with pipeline 2, being used for
The cutting ferrule 5 sealed and the nut 1 being used for compressing cutting ferrule 5；On described joint body 3 and nut 1
It is provided with the screw thread cooperated；Described joint body 3 inner chamber has step, outside this step is with pipeline
Wall pieces together the cavity accommodating O-ring seals 4；O-ring seals 4 makes for silica gel.O shape seals
The string diameter of circle 4 is more than the spacing between cannelure sidewall and pipeline 2 outer wall.Described cutting ferrule 5 front end is squeezed
