Abstract
A pipeline connection component pertains to the technical field of the pipeline connection. The utility model comprises a bolt joint connector, a compression nut and is characterized in that an O-type sealing ring, a retaining ring, an open-loop structural tapered collar are arranged orderly between the connector and the compression nut and used for the pipe sealing and connection; the inner wall of the compression nut is provided with the conical surface corresponding to the tapered collar. The pipeline connection component has the advantages of the simple structure, the low production cost, and the convenient assembly, thereby suitable for various pipeline connections.
Description
Technical field
The utility model belongs to the link technical field, is specially a kind of pipe coupling assembly.
Background technique
Pipeline comprises structures such as straight tube, bend pipe, pipe fitting, according to the difference of material, can be divided into nonmetal or metallic conduits such as plastic tube, plastic-aluminum pipe, copper pipe, steel pipe.Usually adopt copper sleeve cutting ferrule structure to connect between the pipeline, be provided with interior plug, interior plug seal ring, copper snap ring in the copper sleeve, in the plastic-aluminum pipe box is connected on beyond the Great Wall, clamping nut reaches sealing effect by pressing snap ring, its complex structure, assembling are loaded down with trivial details, and the cost of material height uses easy pig copper rust for a long time.
The model utility content
In view of the above-mentioned problems in the prior art, the purpose of this utility model provides a kind of technological scheme of pipe coupling assembly, and it is simple in structure, easy for installation, and cost of production is low.
Described pipe coupling assembly, the connecting head, the clamping nut that comprise threaded, it is characterized in that being equipped with successively between connecting head, the clamping nut taper collar that is used for seal for pipe joints and the O RunddichtringO that is connected, back-up ring, open loop structure, the clamping nut inwall is provided with the conical surface corresponding with the taper collar.
Described pipe coupling assembly is characterized in that the connecting head inner chamber is equipped with interior plug.
Described pipe coupling assembly is characterized in that taper collar inwall is provided with groove.
Described pipe coupling assembly is characterized in that connecting head is straight joint, elbow connection or tee union.
Above-mentioned pipeline adapter assembly, simple in structure, cost of production is low, is applicable to the connection of various pipelines, and is easy to assembly.
Description of drawings
Fig. 1 is the utility model structural representation; Fig. 2 is a taper Spring Clip schematic representation.
Embodiment
As shown in the figure, be equipped with the taper collar 4 that is used for seal for pipe joints and the O-ring seals 2 that is connected, back-up ring 3, open loop structure between connecting head 1, the clamping nut 6 successively, clamping nut 6 inwalls are provided with the conical surface 7 corresponding with taper collar 4, and clamping nut 6 presses taper collar 4 and connecting head 1 threaded.Connecting head 1 is straight joint, elbow connection, tee union or other structure, and connecting head 1 inner chamber can be equipped with and its movable interior plug 8 that cooperates, and connected pipeline 5 cooperates with interior plug 8 inside and outside pegging graft.Taper collar 4 inwalls are provided with the groove 9 that strengthens frictional force, and diameter is slightly less than connecting tube 5, makes it be clamped on pipeline 5 outer walls, improve sealing effect.Press down at clamping nut 6, taper collar 4 and conical surface 7, back-up ring 3 are pressed tight more more, compress O-ring seals 2 and play the effect that close-fitting is tightly connected.By this adapter assembly, can interconnect two pipelines, also can connect the first-class outlet end of the fire hose by connecting head 1 the other end.
When being used for that plastic tube, plastic-aluminum pipe etc. are nonmetal or nonmetal to be connected with metal compounded pipe, this assembly selects for use plastics to make, and can significantly reduce manufacturing cost; When being used for metallic conduits such as steel pipe, copper pipe, this assembly selects for use metallic material to make.
