Abstract
Provided is a stainless steel double clamping sleeve. A front clamping sleeve comprises a front clamping sleeve body and a front end sealing ring located at the front end of the front clamping sleeve body, the rear end of the front clamping sleeve body is provided with a cut-over slope, the inner circle of the front end of a rear clamping sleeve is provided with a cut-over sealing cutting edge, and a stop edge is arranged on the inner circle of the position, at the rear portion of the cut-over sealing cutting edge, of the rear clamping sleeve; the front clamping sleeve body and the rear clamping sleeve are connected front and back, and the outer circle of the front end of the rear clamping sleeve aligns at the cut-over slope; the diameter of the big end of the cut-over slope is greater than that of the outer circle of the front end of the rear clamping sleeve, and the diameter of the small end of the cut-over slope is smaller than that of the outer circle of the front end of the rear clamping sleeve. As the front end rubber ring 1, the cut-over slope 2 and the cut-over sealing cutting edge 3 all make contact with a steel pipe, acting force is more uniform, and the better impact resistance and vibration resistance are achieved. The metal part of the stainless steel double clamping sleeve has the good rigidity and toughness to cut over the steel pipe, and the pressure resistance, vibration resistance and looseness prevention performance of a connector are improved greatly. The stainless steel double clamping sleeve has the specific advantage of being easy and convenient to install.

Technical field
The utility model relates to mechanical field, is applied to the industries such as oil, chemical industry, boats and ships, automobile, railway, especially relates to a kind of stainless steel double card cover.
Background technique
Joint of the prior art is the FBO ready-packaged joint that adopts seal ring seal style, this joint need to regularly replace by the life-span of seal ring, because twolip single deck tape-recorder cover requires very strictly to the mounting process of integral joint, cause occurring in installation process too high reject rate.
Therefore be badly in need of a kind of solution rubber seal weakness, can strengthen the withstand voltage vibration resistance of joint, thereby avoid the new design scheme of the connection of the stainless steel pipeline for joint of frequent renewal part.
Model utility content
The purpose of this utility model is to design a kind of novel stainless steel double card cover, addresses the above problem.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A stainless steel double card cover, comprises front cutting ferrule and rear cutting ferrule, and described front cutting ferrule comprises front cutting ferrule body and the forward end seal circle that is positioned at the front end of described front cutting ferrule body, and the rear end of described front cutting ferrule body is provided with incision inclined-plane; The inner circle of the front end of described rear cutting ferrule is provided with incision sealing cutting edge, and the inner circle of the described rear cutting ferrule at described incision sealing cutting edge rear portion is provided with stop edge; Before and after described front cutting ferrule body and described rear cutting ferrule, join, the cylindrical of the front end of described rear cutting ferrule is aimed at described incision inclined-plane; The Outside diameter on described incision inclined-plane is greater than the outer diameter of a circle of front end of described rear cutting ferrule, and the end diameter on described incision inclined-plane is less than the outer diameter of a circle of front end of described rear cutting ferrule.
Described forward end seal circle is nonmetal seal ring.
Described forward end seal circle is front end rubber seal.
Described front cutting ferrule body is metal material with the described rear cutting ferrule that comprises described incision sealing cutting edge and described stop edge.
Described front cutting ferrule body is stainless steel with the described rear cutting ferrule that comprises described incision sealing cutting edge and described stop edge.
The internal diameter of described incision sealing cutting edge is less than the external diameter of being taken over road.
Distance range between described incision sealing cutting edge and described stop edge is 0.2mm～0.4mm.
The beneficial effects of the utility model can be summarized as follows:
1, the utility model sealing adopts stainless steel with cutting ferrule, takes special thermal treatment explained hereafter to form after machining.By cutting ferrule cutting edge incision steel pipe, make to form between joint and steel pipe linear sealing state, thereby reach the seal request of system.
2, the utility model External Force Acting rotatably compresses cutting ferrule in nut and cuts gradually steel pipe, front end rubber ring 1 press-in connector inclined-plane, incision sealing cutting edge 3 prolongs incision inclined-plane 2 incision steel pipes, and when cutting edge is cut into designed depth, stop edge 4 has limited the excessive incision steel pipe of cutting edge and caused damage.
3, before in the design, cutting ferrule is with rubber seal, and rear cutting ferrule is metal ferrule sealing.Front end rubber ring 1, incision inclined-plane 2 and 3 three of cutting edges of incision sealing all contact with steel pipe, make active force more even, thereby have reached better shock-resistant and shock resistance.
4, the design's double card cover metal partly has good hardness and toughness incision steel pipe, has greatly improved withstand voltage properties, the resistance to shock of joint and has prevented the performance that gets loose.And there is easy-to-install characteristic.
5, the design's metal sealing and the nonmetal sealing characteristic that combines, is guaranteeing, under the prerequisite of pipeline high-pressure tightness, to greatly reduce installation difficulty coefficient.Thereby greatly reduced the reject rate causing because of installation question.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is assembling schematic diagram of the present utility model.
Embodiment
Clearer for technical problem, technological scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
A kind of stainless steel double card cover as depicted in figs. 1 and 2, comprises front cutting ferrule 5 and rear cutting ferrule 6, and described front cutting ferrule 5 comprises front cutting ferrule body and the forward end seal circle 1 that is positioned at the front end of described front cutting ferrule body, and the rear end of described front cutting ferrule body is provided with incision inclined-plane 2; The inner circle of the front end of described rear cutting ferrule 6 is provided with incision sealing cutting edge 3, and the inner circle of the described rear cutting ferrule 6 at described incision sealing cutting edge 3 rear portions is provided with stop edge 4; Described front cutting ferrule body and described rear cutting ferrule 6 front and back join, and the cylindrical of the front end of described rear cutting ferrule 6 is aimed at described incision inclined-plane 2; The Outside diameter on described incision inclined-plane 2 is greater than the outer diameter of a circle of front end of described rear cutting ferrule 6, and the end diameter on described incision inclined-plane 2 is less than the outer diameter of a circle of front end of described rear cutting ferrule 6.Described forward end seal circle 1 is nonmetal seal ring.Described front cutting ferrule body is metal material with the described rear cutting ferrule 6 that comprises described incision sealing cutting edge 3 and described stop edge 4.
