Abstract

The utility model relates to a double-clamping-sleeve joint, and discloses a sealed type double-clamping-sleeve joint. The sealed type double-clamping-sleeve joint sequentially comprises a joint body (1), a front clamping sleeve (3), a rear clamping sleeve (4) and a clamping sleeve nut (5) from left to right, and is further provided with a sealing ring (2). The sealing ring (2) is arranged between the joint body (1) and the front clamping sleeve (3). A left port of the front clamping sleeve (3) is annular. The periphery of the front clamping sleeve (3) is in a circular cone shape. The sealed type double-clamping-sleeve joint keeps the characteristics of two firm supports of double clamping sleeves, combines the characteristic of good sealing performance of the sealing ring, and sufficiently solves the contradiction that the requirement for the sealing performance is high but common machining accuracy of the existing double clamping sleeves can not guarantee the high sealing performance. The sealing ring is added between the joint body and the front clamping sleeve, when the front clamping sleeve presses the sealing ring under the effect of the rear clamping sleeve, due to the fact that the left port of the front clamping sleeve is annular, the sealing ring can not be easily damaged, the sealed type double-clamping-sleeve joint can be repeatedly disassembled and assembled, and sealing is guaranteed.

Description

The two cutting ferrule pipe joints of sealed type
Technical field
The utility model relates to two cutting ferrule pipe joints, has related in particular to the two cutting ferrule pipe joints of a kind of sealed type.
Background technique
Two cutting ferrule joints have the characteristics such as firm, that voltage endurance capability is high, temperature tolerance, and sealing and repeatability are good, the installation maintenance is convenient, safe and reliable that connect.The working principle of two cutting ferrule joints is that steel pipe is inserted in the cutting ferrule, utilizes cutting ferrule nut check, conflict cutting ferrule, incision pipe and sealing.Need not weld when it is connected with steel pipe, be conducive to fire prevention, explosion-proof and high-lift operation, and can eliminate the drawback that welding brings accidentally.Thereby it is a kind of comparatively advanced link in the system automatic control device pipelines such as oil refining, chemical industry, oil, rock gas, food, pharmacy, instrument and apparatus.Be applicable to that pipelines such as oil, gas, water connect.
At present, double-sealing, the solid two Bite type fittingss of two-restriction, the patent No. is 200820034272.3 utility model patent, it is conical that the periphery of its preceding cutting ferrule is, preceding cutting ferrule right output port is provided with 76 degree to the back interior cone angles of 85 degree, and back cutting ferrule left port is provided with 66 degree to the 75 preceding outside cone angles of spending; Because the structure of outside cone angle before cone angle and the back cutting ferrule in behind the preceding cutting ferrule, forward and backward cutting ferrule twice are fastening and seal up pipe simultaneously, play double-sealing, the solid effect of two-restriction, but require than under the condition with higher in sealability, for example under the environment of high vacuum requirement and mesohigh system, existing two cutting ferrule common process precision can't guarantee high sealing.
Summary of the invention
The utility model provides a kind of two cutting ferrule pipe joints of sealed type of favorable sealing property at requiring than guaranteeing high sealing condition shortcoming under the condition with higher in sealability in the prior art.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
The two cutting ferrule pipe joints of sealed type comprise fittings body, preceding cutting ferrule, back cutting ferrule and cutting ferrule nut from left to right successively, also are provided with seal ring, and described seal ring is arranged between fittings body and preceding cutting ferrule.
As preferably, described before the cutting ferrule left port be circular.
As preferably, described before the cutting ferrule periphery be conical.
As preferably, described before the cutting ferrule right output port be provided with cone angle in the back, back cutting ferrule left end is provided with the preceding outside cone angle with the interior cone angle secure fit in back.
As preferably, described fittings body right-hand member is provided with a horn mouth.
The utility model has not only kept the characteristics that two cutting ferrule twice firmly support, also combine the characteristics of seal ring good seal performance, has fully solved the contradiction that sealability requires can't guarantee than higher and existing pair of cutting ferrule common process precision high sealing; Between fittings body and preceding cutting ferrule, increased a seal ring, during the crush seal circle, because preceding cutting ferrule left port is circular, be not easy to damage seal ring under the current effect that is fastened in the back cutting ferrule, can repeat dismounting and guarantee sealing.
Description of drawings
Fig. 1 is the structural drawing before the utility model assembling.
Fig. 2 is the sectional drawing after the utility model assembling.
Fig. 3 is the A portion enlarged view of Fig. 2.
Fig. 4 is the B portion enlarged view of Fig. 3.
The toponym that each number designation refers in the accompanying drawing is as follows: cone angle, 41 in the 1-fittings body, 2-seal ring, 3-preceding cutting ferrule, 4-back cutting ferrule, 5-cutting ferrule nut, 6-pipe, 31-back-preceding outside cone angle wherein.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Embodiment 1
The two cutting ferrule pipe joints of sealed type as shown in Figures 1 to 4, comprise fittings body 1, preceding cutting ferrule 3, back cutting ferrule 4 and cutting ferrule nut 5 from left to right successively, also are provided with seal ring 2, and described seal ring 2 is arranged on 3 of fittings body 1 and preceding cutting ferrules.
Cutting ferrule 3 left port are circular before described.Cutting ferrule 3 peripheries are conical before described.Cutting ferrule 3 right output port are provided with cone angle 31 in the back before described, and back cutting ferrule 4 left ends are provided with the preceding outside cone angle 41 with interior cone angle 31 secure fit in back.Described fittings body 1 right-hand member is provided with a horn mouth.
With seal ring 2, preceding cutting ferrule 3 and back cutting ferrule 4 are sealed in fittings body 1 and the cutting ferrule nut 5 by cutting ferrule nut 5, fittings body 1 one ends and cutting ferrule nut 5 one ends are all suitable with pipe 6 calibers, seal ring 2 and preceding cutting ferrule 3 are under the drive of back cutting ferrule 4, with closely knit cooperation of horn mouth of fittings body 1 right-hand member, and press pipe 6, back cutting ferrule 4 is under the drive of cutting ferrule nut 5, with back interior 31 closely knit cooperations of cone angle of preceding cutting ferrule 3, and press pipe 6, realize that two cutting ferrule twice firmly support, and the seal ring 2 that is provided with is under the drive of preceding cutting ferrule 3, can reach good sealing property, solve the contradiction that sealability requires can't guarantee than the higher and existing pair of cutting ferrule common process precision high sealing.
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
