The beneficial effects of the utility model are that: the utility model relates to a compression pipe fitting is the various pipelines of connection of safety fast, and need not to use welding equipment, and the dismantlement that can relapse is used. Because compression pipe fitting's structure and the uniqueness of materials used, make compression pipe fitting's shock resistance, resistance to chemical corrosion ability and heat resistance have obtained the improvement. In addition the material that uses of compression pipe fitting be nontoxic, pollution -free material, can repeat cyclic utilization, avoided environmental pollution.
Description
Technical field
The utility model relates to a kind of connection set, is specifically related to a kind of compression pipe fitting.
Background technique
Pipeline is the device of fluid for carrying gas, liquid or band solid particle connected into pipe, pipe connection and valve etc.Having many uses of pipeline is general, is mainly used in feedwater, draining, heat supply, supplies in heating installation, long distance delivery oil and natural gas, agricultural irrigation, hydraulic engineering and various commercial plant.
The connecting means of pipeline comprises the pipeline Placements such as pipeline screwed connection, piping flange connection, pipeline welding, pipeline socket connection, pipe bonding connection, the connection of pipeline FERRULETYPE, pipe hot melting connection, dike field, but these Placement more complicated, need have special requirement to pipeline.
Model utility content
In order to solve the problems referred to above that prior art exists, the utility model provides the compression pipe fitting of the connecting tube that a kind of Placement is simple and tightness is stronger.
The technological scheme that the utility model adopts is:
A kind of compression pipe fitting, the connecting body comprising the collar nut of coaxial setting, jump ring, gasket ring, rubber ring and match with collar nut, described jump ring, described gasket ring, described rubber ring are from left to right filled in described collar nut successively, and described collar nut and described connecting body are connected to be formed and compress pipe fitting.In use, first collar nut is enclosed within pipeline, more successively the connecting body that jump ring, gasket ring, rubber ring, collar nut match is enclosed within pipeline, the connecting body that collar nut and collar nut match is tightened, can be connected between pipeline with pipeline.
Further, the supporting frame preventing jump ring from coming off is provided with in described collar nut.
Further, inside the right-hand member of described collar nut, be provided with internal thread, outside the left end of described connecting body, be provided with the outside thread matched with described internal thread.
Further, described collar nut is made up of polypropylene.Described collar nut is made up of atactic copolymerized polypropene, and atactic copolymerized polypropene is also polyacrylic one, and the basic structure of its macromolecular chain is with adding the modification in addition of different types of monomer molecule.Random copolymer improves optical property, improves shock resistance, adds flexibility.
Further, described jump ring is made up of polyoxymethylene.Polyoxymethylene is a kind of elastic material, even if still have good creep resistant characteristic, geometrical stability and impact property at low temperatures.Polyoxymethylene is crystalline material and not easily absorbs moisture, and its high crystallization degree causes it to have quite high shrinkage, and the fatigue resistance of polyoxymethylene, creep resistant, hardness and water resistence are better than nylon.The pressure that the use of polyoxymethylene jump ring can prevent from getting loose voluntarily and pipeline brings due to vibration, bears the high thrust load of pipeline and one-sided tic.
Further, described gasket ring is made up of polypropylene.Described gasket ring also has atactic copolymerized polypropene to make.
Further, described rubber ring is made up of the fine rubber and plastic of fourth.Nitrile butadiene rubber is obtained through emulsion polymerisation by butadiene and acrylonitrile.There is good water resistence, tightness and excellent cohesiveencess, its oil resistance and oil resistance are also higher, be widely used in the various oil resistant rubber goods of system, as multiple oil seat gasket, pad, sleeve pipe, flexible package etc., it is requisite elastic material in the industries such as automobile, aviation, oil, duplicating.The connection that the use of rubber ring is pipeline provides the system of a reliable closed conduit, because its elasticity is larger, even if behavior is more too drastic also can not bring infringement to pipe fitting.
The beneficial effects of the utility model are: the utility model is a kind of compress pipe fitting can the various pipeline of connection fast and safely, and without the need to using welding equipment, can dismounting repeatedly to use.The use of polyoxymethylene jump ring can prevent from compressing the pressure that the self falling of pipe fitting and pipe vibration bring, and also can bear high thrust load and the one-side tic of pipeline; The use of rubber ring provides a reliable closed conduit system, and pipeline can be made to bear aggressive behavior to a certain degree.Due to the structure of described compression pipe fitting and the uniqueness of use material, the shock resistance of described compression pipe fitting, resistance to chemical corrosion and resistance to heat is made to be obtained for raising.In addition the material that described compression pipe fitting uses is nontoxic, nonpollution material, repetitive cycling can utilize, avoids environmental pollution.
Accompanying drawing explanation
Fig. 1 is the perspective view that compression pipe fitting described in the utility model assembles;
Fig. 2 is the structural representation that compression pipe fitting described in the utility model is taken apart.
In figure: 1, collar nut; 2, jump ring; 3, gasket ring; 4, rubber ring; 5, connecting body.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, will be described in detail the technical solution of the utility model below.Obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, other mode of executions all that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belong to the scope that the utility model is protected.
A kind of compression pipe fitting as depicted in figs. 1 and 2, the connecting body 5 comprising collar nut 1, jump ring 2, gasket ring 3, rubber ring 4 and match with collar nut 1, described jump ring 2, described gasket ring 3, described rubber ring 4 are from left to right filled in described collar nut 1 successively, be provided with the supporting frame preventing jump ring 2 from coming off in described collar nut 1, the connecting body 5 that described collar nut 1 and collar nut 1 match coordinates to be formed and compresses pipe fitting.In use, first collar nut 1 is enclosed within pipeline, again successively by jump ring 2, gasket ring 3, rubber ring 4 and be enclosed within pipeline with the connecting body 5 that collar nut 1 matches, the connecting body 5 that collar nut 1 and collar nut 1 match is tightened, can be connected between pipeline with pipeline.Left and right directions is herein the left and right directions in Fig. 1.
As the scheme of comparative optimization, inside the right-hand member of described collar nut 1, be provided with internal thread, outside the left end of described connecting body 5, be provided with the outside thread matched with described internal thread.Described internal thread and described outside thread coordinate and are connected with described connecting body 5 by described collar nut 1.
As the preferred embodiment of one, described collar nut 1 is made up of polypropylene.
For increasing the fatigue resistance of jump ring 2, creep resistant, hardness and water resistence, described jump ring 2 is made up of polyoxymethylene.The pressure that the use of polyoxymethylene jump ring 2 can prevent from getting loose voluntarily and pipeline brings due to vibration, bears the high thrust load of pipeline and one-sided tic.
As one preferred embodiment, described gasket ring 3 is made up of polypropylene.
For increasing the sealing of pipeline, described rubber ring 4 is made up of butyronitrile rubber and plastic, and the connection that the use of rubber ring 4 is pipeline provides the system of a reliable closed conduit, because its elasticity is larger, even if behavior is more too drastic also can not bring infringement to pipe fitting.
