Abstract
A stainless steel double-edge single clamping sleeve comprises a clamping sleeve body, wherein the inner circle of the front end of the clamping sleeve body is provided with an annular cut-over sealing front edge and an annular cut-over sealing rear edge in sequence from front to back, and a stop edge is arranged on the inner circle, at the rear portion of the cut-over sealing rear edge, of the clamping sleeve body. The clamping sleeve body comprising the cut-over sealing front edge, the cut-over sealing rear edge and the stop edge is made of stainless steel. The clamping sleeve for sealing is made of stainless steel, and is formed through the special heat treatment process after being machined. A connector and a steel pipe are in the linear sealing state by cutting over the steel pipe through the edges of the clamping sleeve, and the sealing requirement of a system is met. The stop edge 3 can limit the edges from excessively cutting over the steel pipe and damaging the steel pipe. The cut-over sealing front edge 1, the cut-over sealing rear edge and the stop edge 3 all make contact with the steel pipe, so that the acting force is more uniform, and the better impact resistance and vibration resistance are achieved.
Description
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 twolip single deck tape-recorder 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 twolip single deck tape-recorder cover, addresses the above problem.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of stainless steel twolip single deck tape-recorder cover, comprise cutting ferrule body, the incision sealing rear edge that is provided with successively from front to back incision sealing front edge and the ring-type of ring-type in the inner circle of the front end of described cutting ferrule body, the inner circle of the described cutting ferrule body at the rear portion of described incision sealing rear edge is provided with stop edge.
The described cutting ferrule body that comprises described incision sealing front edge, described incision sealing rear edge and described stop edge is metal material.
The described cutting ferrule body that comprises described incision sealing front edge, described incision sealing rear edge and described stop edge is stainless steel.
The internal diameter of described incision sealing front edge and described incision sealing rear edge is all less than the external diameter of being taken over road.
Distance range between described incision sealing front edge and described incision sealing rear edge is 0.2mm-0.4mm; Distance range between described incision sealing rear edge and described stop edge is 0.2mm-0.4mm.
The design can be applicable to railcar, can also be applied to the fields such as oil, petrochemical industry, boats and ships.
The beneficial effects of the utility model can be summarized as follows:
1, sealing of the present utility model 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, in use, External Force Acting rotatably compresses cutting ferrule in nut and cuts gradually steel pipe as shown in Figure 2, incision sealing front edge 1 and incision sealing rear edge 2 are cut steel pipe in succession, and when two cutting edges are all cut into designed depth, stop edge 3 has limited the excessive incision steel pipe of cutting edge and caused damage.
3, incision sealing front edge 1, rear edge all contact with steel pipe with 3 three of stop edge, make active force more even, thereby have reached better shock-resistant and shock resistance.
4,, in the design, cutting ferrule has good hardness and toughness incision steel pipe simultaneously.Greatly improved withstand voltage properties, the resistance to shock of joint and prevented the performance that gets loose.And can guarantee the use of cutting ferrule repeated disassembled and assembled.
Accompanying drawing explanation
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 twolip single deck tape-recorder cover as depicted in figs. 1 and 2, comprise a kind of stainless steel twolip single deck tape-recorder cover, comprise cutting ferrule body 4, the incision sealing rear edge 2 that is provided with successively from front to back incision sealing front edge 1 and the ring-type of ring-type in the inner circle of the front end of described cutting ferrule body 4, the inner circle of the described cutting ferrule body at the rear portion of described incision sealing rear edge 2 is provided with stop edge 3.Wherein, the described cutting ferrule body that comprises described incision sealing front edge 1, described incision sealing rear edge 2 and described stop edge 3 is metal material.The internal diameter of described incision sealing front edge 1 and described incision sealing rear edge 2 is all less than the external diameter of being taken over road.
In the embodiment who is more preferably, comprise that the described cutting ferrule body of described incision sealing front edge 1, described incision sealing rear edge 2 and described stop edge 3 is stainless steel.Distance range between described incision sealing front edge 1 and described incision sealing rear edge 2 is 0.2mm-0.4mm; Distance range between described incision sealing rear edge 2 and described stop edge 3 is 0.2mm-0.4mm.
In use, External Force Acting is in nut 5 rotations, compression inclined-plane 8 on fittings body 7 compresses cutting ferrule and cuts gradually steel pipe 6 as shown in Figure 2, incision sealing front edge 1 and incision sealing rear edge 2 are cut steel pipe 6 in succession, when two cutting edges are all cut into designed depth, stop edge 3 has limited the excessive incision steel pipe of cutting edge and has caused damage.Incision sealing front edge 1, rear edge all contact with steel pipe 6 with 3 three of stop edge, make active force more even, thereby have reached better shock-resistant and shock resistance.In the design, cutting ferrule has good hardness and toughness incision steel pipe simultaneously.Greatly improved withstand voltage properties, the resistance to shock of joint and prevented the performance that gets loose.And can guarantee the use of cutting ferrule repeated disassembled and assembled.
More than by the detailed description of concrete and preferred embodiment the utility model; but those skilled in the art should be understood that; the utility model is not limited to the above embodiment; all within spirit of the present utility model and principle; any modification of doing, be equal to replacement etc., within all should being included in protection domain of the present utility model.
