Description
Technical field
The utility model belongs to jointing technical field, particularly relates to a kind of integrated type ferrule fitting connecting for pipeline.
Background technique
At present, when low-pressure gas pipeline connects, general method is the mode that adopts (sphere or the conical surface) cutting ferrule to connect.The ferrule fitting of prior art comprises cutting ferrule and pressure cap, in use, first cutting ferrule and pressure cap are nested into successively on the pipe fitting that needs to be connected, by cutting ferrule and pressure cap, pipe fitting is connected on pipe joint subsequently, but because pressure cap and cutting ferrule are split-type structural, and cutting ferrule small volume, need to place respectively and carry, in the process of using in reality, when placing and carrying, pressure cap or cutting ferrule are easily lost, and then the situation that causes scene to install; While installing, need two steps, installation efficiency is easily subject to the impact of the factors such as installation personnel qualification, field installation environment and cutting ferrule and pressure cap quality of processing, causes installation efficiency lower simultaneously; Moreover because cutting ferrule and pressure cap are separate machined, machining accuracy is larger on connective stability impact, makes the connection of this ferrule fitting have problem unreliable, easy leakage.
Model utility content
It is integral type structure that the utility model provides a kind of pressure cap and cutting ferrule for above problem, places and carries difficult loss, and installation efficiency is higher, connection reliability is better and antileakaging integrated type ferrule fitting.
The utility model is to overcome the above problems technological scheme used to be: a kind of integrated type ferrule fitting with following structure is provided, it comprises cutting ferrule and pressure cap, described pressure cap is divided into helical thread portion and spanner retained part, described cutting ferrule is connected on helical thread portion and the end position away from spanner retained part, the axis of cutting ferrule and the axis of helical thread portion are on same straight line, and cutting ferrule and helical thread portion are integral type structure, the cross section of described cutting ferrule is trapezium structure, and cutting ferrule internal surface corresponding to trapezium structure below.
Adopt after above structure, compared with prior art, the utility model, because cutting ferrule and pressure cap are integral type structure, just does not need separately place in addition and carry when placing and carrying, and places and carry more convenient, is not just prone to the situation of component loss yet, simultaneously, during installation, the utility model integral body is inserted on pipe fitting and can be connected with pipe joint, and installation efficiency is higher, and common workman can install, the installation personnel that does not need professional training, and integral structure makes cutting ferrule relatively consistent with pressure cap machining accuracy, can effectively eliminate the impact of original two machining accuracies stack on installation efficiency, and there is no the cutting ferrule finding of independent split, also the impact that is not just subject to environment causes the situation of cutting ferrule loss, therefore installation efficiency is higher, moreover, the cross section of cutting ferrule is trapezium structure, when pressure cap and pipe joint locking, pressure cap and cutting ferrule disconnect from joint, subsequently along with pressure cap continues precession, the inclined-plane laminating of the inclined-plane of cutting ferrule one end and pipe joint inwall, and cutting ferrule the other end inclined-plane can be inserted into the effect of playing swelling in the gap between pressure cap and pipe fitting, and when screwing into locked position, cutting ferrule can be out of shape, thereby when cutting ferrule one end and pipe joint inwall are close to, the cutting ferrule the other end hugs pipe fitting, make between cutting ferrule and pipe fitting and cutting ferrule and pipe joint between the better reliability that is not only connected, sealing is also better.Therefore the utlity model has pressure cap with cutting ferrule is integral type structure, place and carry and be difficult for loss, installation efficiency is higher, connection reliability is better and antileakaging feature.
As improvement, on described helical thread portion inwall, the position of nearly cutting ferrule is provided with " V " font groove of annular, described diameter corresponding to " V " font bottom portion of groove is greater than the external diameter of cutting ferrule and helical thread portion joint, and the angle of described " V " font groove is 70～110 °; After " V " font groove arranges, while making cutting ferrule enter the gap between pressure cap and pipe fitting from post-rift end, joint, the post-rift end of cutting ferrule can closely be coated on pipe fitting under the guiding of " V " font recess sidewall, can further improve the seal between cutting ferrule and pipe fitting, make not more to be prone to after connection of the present utility model the situation of leakage; And diameter corresponding to " V " font bottom portion of groove is greater than the external diameter of cutting ferrule and helical thread portion joint, can effectively avoid occurring that helical thread portion outwards knocks over the post-rift end of cutting ferrule the situation of volume, make the post-rift end of cutting ferrule all can enter into the gap between pressure cap and pipe fitting, and then guarantee the reliability of the utility model connection and the stability of use.
As further improvement, described " V " font bottom portion of groove is 0.2～0.8: 10 to the distance between helical thread portion and the end face of cutting ferrule joint with the ratio of helical thread portion internal diameter; , under such ratio,, when pressure cap precession, more easily rupture in helical thread portion and cutting ferrule joint, the reliability after can further guaranteeing stability in use of the present utility model and be connected.
As further improving, the degree of depth of described " V " font groove is 0.2～0.6mm again; The V of this depth bounds " font groove is easier to processing, can cut down finished cost; And this depth bounds also can guarantee the reliability rupturing in helical thread portion and cutting ferrule joint when pressure cap precession.
As further improving, described trapezium structure is isosceles trapezoidal structure, and the length of trapezoidal top is 0.3～0.9: 5.5 with the ratio of following length; , under this ratio, between cutting ferrule and pipe joint, degree of laminating is better, and is also easier to be squeezed in the gap of pressure cap and pipe fitting after being fastened in joint fracture, and then the sealing reliability after making stability in use of the present utility model and being connected is all better.
As preferably, described angle is 80～100 °.
As preferably, described ratio is 0.4～0.6: 10.
As preferably, the degree of depth of described " V " font groove is 0.2～0.4mm.
As preferably, described ratio is 0.5～0.7: 5.5.
