The loading facility that use in the present embodiment are the commercially available prod.The content that does not describe in the present embodiment is an existing technology, so, no longer give unnecessary details.
The working principle of the utility model pipe connector lug:
The non-outer extrusion ring front end sleeve of joint that is welded to connect of the utility model pipeline is on matrix; During installation pipeline one end is inserted the inner and location of matrix, load at twice through the external load facility then, loading for the first time is to push the outer extrusion ring of matrix one end to the matrix middle part earlier; Force two outer lug generation radial contraction of this end on the matrix; Two internal projection that matrix is corresponding with two outer lug thereupon tightly interlock are lived the pipeline outer wall face, the internal thread segment ascending pipe pipeline outer wall face that matrix should end simultaneously, and at this moment internal thread segment is along circumferential equally distributed 8 opening slots; Can be beneficial to the radial contraction of internal thread segment, accomplish being connected of an end pipeline and joint matrix; Load for the second time be with load for the first time the outer extrusion ring that same mode loads the matrix the other end, accomplish being connected of the other end pipeline and joint matrix, withdraw the loading facility at last.
When adopting the utility model pipe connector lug to carry out the pipeline connection; Because the cylndrical surface internal diameter between the conical surface of outer extrusion ring is less than the maximum outside diameter of matrix internal thread segment and outer lug; Push that the external diameter of internal thread segment and outer lug constantly reduces in the moving process squeezing; Force the screw thread wedge angle and the twice internal projection ascending pipe pipeline outer wall face of internal thread segment, thereby make matrix and pipeline form reliable sealing, simultaneously because the effect of internal thread segment; Can prevent effectively that pipeline is pulled out from matrix inside, therefore connect satisfactory for result.
In the pipeline connection procedure, load force bearing ring and point of application of force is provided to setting tool, in addition, the axial length of this loading force bearing ring is one and loads stroke, can prevent that the stroke of outer extrusion ring in installation process is excessive.
In loading procedure is installed, let outer extrusion ring slowly and equably be pressed into to loading force bearing ring by the matrix thread section, realize that the matrix outer lug cooperates with the cylindrical interference of outer extrusion ring, thereby make matrix produce radial contraction.Matrix near the external diameter of the outer lug that loads force bearing ring greater than outer lug external diameter near thread section; And preceding cylinder internal diameter is greater than the external diameter near the outer lug of thread section; And less than near the outer lug that loads force bearing ring external diameter; Can let inner cone, the middle conical surface, install the starting stage respectively two outer lug contact simultaneously; Thereby guarantee installation process along with outer extrusion ring by the matrix thread section when the loading force bearing ring direction at matrix middle part moves, two internal projection are synchronous also, steps up pipeline synchronously.The length of inner cone, the middle conical surface and rear cone is a stroke that loads load, and therefore can accurately control outer lug presses down stroke, prevents that effectively outer extrusion ring from installing back ejection matrix.In addition; After joint was installed, the preceding cylinder of outer extrusion ring and matrix formed interference fit near the outer lug that loads force bearing ring, and middle cylinder and matrix form interference fit near the outer lug of thread section; Back cylinder matches with matrix thread section outer surface; Realize outer lug, internal projection, the synchronous radial contraction of thread section, clamping pipe makes connection satisfactory for result.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technological scheme any simple modification, equivalent variations and modification that above embodiment did.
