Description
Technical field
The utility model relates to a kind of fluid pipe-line connection set, especially relates to a kind of high pressure fluidline seal connection.
Background technique
In fluid (gas, liquid) transfer line, often need to install some links, as needle-valve, ball valve, pressure gauge, threeway, how logical etc.The sealing problem of the joint of these links and pipeline is under puzzlement people's the situation of technical barrier, particularly high-pressure delivery always.For example store the well for storage of high pressure gas of compressed natural gas (CNG), just can there be the serious potential safety hazard of consequence up to 25MPa in its air pressure in case take place to reveal.And when revealing maintenance, need carry out emptying process, cause a large amount of wastes and the environmental pollution of the energy the rock gas in the gas storage well.At present, solving link mainly contains tapering screwed connection sealing with the technological means of pipeline junction sealing problem and is connected sealing with FERRULETYPE.The former major defect is that owing to adopt thread seal to connect, so the quality of processing of double thread and installation quality require height, and sealing is poor in the utilization of reality, and destroys screw thread when dismounting easily, thereby reusability is poor.The latter's major defect is, because the employing end face seal, so very high to the material and the suface processing quality requirement of pipeline, thereby cost an arm and a leg the cost height.
Summary of the invention
The technical problems to be solved in the utility model is, overcomes the shortcoming of prior art, and a kind of good seal performance, convenient disassembly, repeat performance is good and cost is low high pressure line seal connection are provided.
For solving the problems of the technologies described above, the utility model has adopted following technical proposals: a kind of high pressure line seal connection, comprise link, gland nut, pipeline, and the termination outer wall of this pipeline is taper, have circular groove on the cone-shaped end, circular groove is embedded with seal ring; The straightway outer wall of pipeline also has circular groove near the cone-shaped end position, and this circular groove is embedded with cuts the formula cutting ferrule open; The connection mouth of link is and the suitable taper of the conical section of pipeline; Gland nut is fixed into the cone-shaped end of pipeline in the connection mouth of link by cutting the formula cutting ferrule open.
The beneficial effects of the utility model are: 1. because the mode that has adopted the rubber seal double seal of tapering sealing between the connection mouth of pipeline outer wall and link and seal ring to combine, thereby the significant sealing affection raising, the reliability height improved Safety performance.2. owing to be not to adopt to be threaded but to adopt tapering to be connected between pipeline and the link, so the difficulty of processing reduction, repeat performance is good and mount and dismount more convenient.3. because to the mode that adopts gland nut to combine that is connected between pipeline and the link, so connection is more reliable with the formula cutting ferrule of cutting open.4. cutting ferrule is promptly combined by two-part of cutting open in advance for cutting formula open, so installation is more convenient, manufacture cost is lower.5. because link can be straight-through, threeway, how logical or valve member etc. more than the threeway, thereby applied range.
The end face that compresses of above-mentioned gland nut is taper, and cooperates with the conical outer wall of cutting the formula cutting ferrule open.
Because gland nut is a taper connection with cutting open between the formula cutting ferrule, thereby compresses the connection better effects if, dismantles more convenient.
The above-mentioned outer wall of cutting the formula cutting ferrule open is step-like.
The outer wall of cutting the formula cutting ferrule open is processed into step-like, just can makes the end face that compresses of gland nut not need to carry out special processing, that is to say, can utilize the gland nut that generally uses at present.Thereby making accommodation of the present utility model wider, the repacking cost is lower.
Above-mentioned link is for the above how logical or valve member of straight-through, threeway, threeway etc.

Embodiment
Fig. 1,2,3 illustrates, and present embodiment mainly comprises link 1, gland nut 5, pipeline 2.The termination outer wall of pipeline 2 is taper, has circular groove on the cone-shaped end, and circular groove is embedded with seal ring 4.The straightway outer wall of pipeline 2 also has circular groove near the cone-shaped end position, and this circular groove is embedded with cuts formula cutting ferrule 3 open, and this cuts two-part that formula cutting ferrule 3 is cut open for symmetry open.The end face that compresses of gland nut 5 is taper.And the outer wall of cutting formula cutting ferrule 3 open also is taper, and its tapering is identical with the tapering that compresses end face of gland nut 5.The connection mouth of link 1 is and the suitable taper of the conical section of pipeline 2.Gland nut 5 is fixed into the cone-shaped end of pipeline 2 in the connection mouth of link 1 by cutting formula cutting ferrule 3 open.
During installation, earlier gland nut 5 is inserted on the outer wall of pipeline 2, the formula of cutting open the cutting ferrule of then symmetry being cut open 3 embeds pipeline 2 straightway outer walls near in the circular groove at cone-shaped end position.Then with in the circular groove on the cone-shaped end of seal ring 4 embedding pipelines 2.At last with being threaded on gland nut 5 and link 1 outer wall, and the cone-shaped end of pipeline 2 is fixed in the connection mouth of link 1 by cutting formula cutting ferrule 3 open.
During dismounting, unclamp gland nut 5, just pipeline 2 can be taken out from the connection mouth of link 1.
The utility model can be applied to the various high pressure fluidlines occasion that is tightly connected, its link 1 can be lead directly to, how logical or valve member that threeway, threeway are above etc.The combining form of various links and pipeline is varied, and is unrestricted.Promptly illustrate as Fig. 4, the utility model is applied to store the situation that the well head seal for pipe joints of the well for storage of compressed natural gas (CNG) connects.The link 1 of this moment is two valve members and a threeway.Link 1 realizes that by above linkage structure mode high pressure sealing is connected with the pipeline 2 between it, can guarantee that the safety and the nothing of the well head of well for storage of high pressure gas leaked.
Present embodiment and embodiment's 1 structure is basic identical.Its difference is shown in Fig. 5,6, and the outer wall of cutting formula cutting ferrule 3 open is step-like, and with tapering transition, this tapering transition face matches with the chamfering that compresses between end face and the internal surface of gland nut 5 between two table tops of step.
The shape of cutting the outer wall of formula cutting ferrule 3 open can be other shapes, and the compressing end surface shape and also can change to some extent of gland nut 5 is as long as can make the outer wall of cutting formula cutting ferrule 3 open and the end face that compresses of gland nut 5 match.
