Description
Technical field
The utility model relates to a kind of for the cutting ferrule in pipe fitting joint, is a kind of three sealing metal rubber cutting ferrules specifically.
Background technique
Traditional is fastened in through after prepackage or distortion, cutting ferrule surface of contact is a point, sealing (point-to-area sealing) to the conical surface, in high pressure and pulse situation, easily cause leakage, and traditional Bite type fittings relies on Metal Contact sealing, being dismounted for multiple times is easily out of shape, weares and teares, causes leakage, thereby changes joint, cutting ferrule or change steel pipe, and maintenance price is high.
Model utility content
For the problems referred to above, of the present utility model design a kind of seal reliable, assemble joint cutting ferrule simple and easy to maintenance, the problem existing to solve prior art.
Technical solutions of the utility model are: comprise stuffing box gland and cutting ferrule, described stuffing box gland is by rubber ring and be embedded in the metal ring being integrated with rubber ring in rubber ring and form, described metal ring endoporus is cone shape hole, aperture place, cone shape hole two ends is respectively equipped with a circle and protrudes annular ring, and described cutting ferrule right-hand member is stuck in cone shape hole.Described cutting ferrule is flange-type structure, and its left end is flange, and right-hand member is straight connector, and straight connector port exterior angle is provided with chamfering, and chamfer angle is: 13 °, ledge surface is provided with chamfering, and chamfer angle is 30 °-90 °.Described stuffing box gland is flange-type structure, and its left end is flange, and right-hand member is taper joint.
The beneficial effects of the utility model: joint cutting ferrule of the present utility model, the structure having matched by having designed cutting ferrule and stuffing box gland, structure uniqueness, sealing is listed as.Because the combination of metal ferrule and rubber sealing boot, not only reach stuffing box gland and pipe junction point good have a sealing, and also ensured clamping sealing for stretching into pipeline in metal ferrule because of the cone structure in stuffing box gland, and had anti-tripping effect.In addition, the utility model assembly parts are simple, safeguard and change conveniently.
Brief description of the drawings
Structural representation when Fig. 1 is assembling of the present utility model.
Fig. 2 is the partial enlarged drawing at the utility model A point place.
Fig. 3 is the partial sectional view of the utility model cutting ferrule.
Embodiment
Technical problem, technological scheme and the beneficial effect that will solve in order more to clearly demonstrate the utility model patent, below in conjunction with Figure of description and embodiment, be further elaborated to the utility model.
As illustrated in fig. 1 and 2, comprise stuffing box gland 3 and cutting ferrule 2, described stuffing box gland 3 is made up of rubber ring 6 and the metal ring 7 that is embedded in rubber ring 6 and rubber ring is integrated, described metal ring 7 endoporus are cone shape hole, aperture place, cone shape hole two ends is respectively equipped with a circle and protrudes annular ring 8, and described cutting ferrule 2 right-hand members are stuck in cone shape hole.Described cutting ferrule 2 is flange-type structure, and its left end is flange, and right-hand member is straight connector 9, and straight connector 9 port exterior angles are provided with chamfering B, and chamfering B angle is: 13 °, ledge surface is provided with chamfering C, and chamfering C angle is 30 °-90 °.Described stuffing box gland 3 is flange-type structure, and its left end is flange, and right-hand member is taper joint
The utility model is established for pipeline and is connected, and connect the assembly of using and also comprise joint 4, nut 5, joint 4 mouth of pipe places are the taper mouth of pipe, and Placement is: joint 4 left sides are socketed with stuffing box gland 3, cutting ferrule 2 and nut 5 successively, and cutting ferrule 2 right-hand members are stuck in cone shape hole.
Above-mentioned connection has the feature of sealing and good stability.Its former because: due to be embedded at the utility model stuffing box gland install a metal ring, metal annular distance inwall is designed to the conical surface, so cutting ferrule 2 is stuck in after metal ring 7 endoporus, by outside nut 5 to cutting ferrule applied thrust, cutting ferrule 2 and stuffing box gland are tightly clamped, and cutting ferrule 2 front positions are due to the thrust of nut 5, under the effect of metal ring 7 conical surface of inboard wall, cutting ferrule 2 front positions produce elastic strain, cutting ferrule 2 is contacted closely with joint 4 inwalls, seal more reliable, and because pipeline 1 is tightly pushed down in the elastic strain of cutting ferrule 2, thereby complete twin conduit 1 is fixing, a circle in the design of metal ring 7 inwall two edges protrudes annular ring 8, not only can after installing, pipeline play fixation to pipeline, make pipeline more stable, and in high pressure and pulse situation, metal ring can play good anti-tripping effect to cutting ferrule, strengthen the stability of joint.Meanwhile, because stuffing box gland is that quality of rubber materials is made, ensured the sealing of outer ring.
The foregoing is only an embodiment of the present utility model; not in order to limit the utility model; all the utility model person of ordinary skill in the field to described specific embodiment make various amendments or supplement; or be equal to replacement and improvement etc., within all should being included in protection domain of the present utility model.
