Abstract
The utility model relates to an inserting type connecting pipe fitting of a hard plastic pipeline, which belongs to the technical field of a pipeline connecting piece. The utility model comprises a pipe liner and a clamp sleeve which is sheathed on the connecting end opening of the pipe liner. The utility model is characterized in that a cavity is formed between the clamp sleeve and the pipe liner, and is used for inserting the pipe to be connected; the cavity is internally provided with a U-shaped liner sleeve in a matching way, and the inner surface and the outer surface of the U-shaped liner sleeve are matched with sharp teeth. The inserting type connecting pipe fitting of a hard plastic pipeline is novel in design, and reasonable in concept. When the connecting pipe fitting is used for connecting PEX aluminum-plastic compound pipes, only the pipes to be connected are inserted into the connecting pipe fitting, and then the pipelines are connected. The utility model has convenient and rapid construction and installation, thoroughly overcomes the defects of the unreliable connection, high cost, long construction period and the like existing in the traditional sweating soldering pipe fittings in home, and is favorable for reducing the manufacture cost of the system and shortening the construction period.
Description
Technical field
The utility model belongs to the pipe joint technical field, is specifically related to a kind of hard plastic pipe plug-in type connection pipe fitting that the plastic-aluminum combined pipeline of floor heating PEX connects that is particularly useful for.
Background technique
In the face of energy environment in short supply day by day, build the theme that energy-efficient society has become the epoch.Special China, can energy problem has become influence keep one of principal element of economic fast and stable development, at building field, the new technique of low energy consumption energy-conserving and environment-protective more and more obtains the attention of national correlation department, and has been made stipulations in relevant laws and regulations and promoted the use of with pressure.Under this background, PEX aluminium-plastic composite pipe floor heating technology is able to large-scale promotion in China and uses.In this heating system, generally all be to adopt mechanical clamping type to connect between the plastic pipe, the more ubiquitous problems of this Placement have limited higher generalization, as connect unreliable, the time have water leakage phenomenon to take place; Connection pipe fitting is a metalwork, system's manufacturing, maintenance cost height; And long construction period, construction complexity etc.
The model utility content
The utility model aims to provide a kind of hard plastic pipe plug-in type connection pipe fitting technological scheme, changes the Placement of waiting to take over material, to overcome problems of the prior art.
Described hard plastic pipe plug-in type connection pipe fitting, comprise the pipe lining and be socketed in the cutting ferrule that pipe serves as a contrast the connecting port, it is characterized in that is configured for pegging graft between cutting ferrule and the pipe lining waits to take over the cavity of material, is equipped with U type lining in the cavity, and the inner and outer surface of U type lining is equipped with pointed tooth.
Described hard plastic pipe plug-in type connection pipe fitting is characterized in that described pipe lining connecting port outer surface is equipped with seal groove, is equipped with seal ring in the seal groove.
Described hard plastic pipe plug-in type connection pipe fitting is characterized in that in the described cavity and U type lining opening end position is managed the lining outer surface accordingly, the cutting ferrule internal surface is respectively ramp structure, and described inclined-plane touches along side bumper with U type lining opening end respectively and cooperates.
Described hard plastic pipe plug-in type connection pipe fitting is characterized in that described pipe lining, cutting ferrule cooperate by collar, the groove interlocking of relative set on two fitting surfaces.
Described hard plastic pipe plug-in type connection pipe fitting is characterized in that being equipped with stiffening rib on the pipe lining outer surface between the adjacent cutting ferrule.
Described hard plastic pipe plug-in type connection pipe fitting is characterized in that described pipe lining (1) is elbow, straight-through, threeway or four-way structure.
Above-mentioned hard plastic pipe plug-in type connection pipe fitting modern design, reasonable idea, when adopting described connection pipe fitting to carry out the connection of PEX aluminium-plastic composite pipe, only need to wait to take over material and directly insert the connection that just can realize between the pipeline, construction install convenience is quick, solved thoroughly that the connection that exists in the domestic conventional hot melt weld-end fittings is unreliable, defectives such as pipe fitting cost height and long construction period, help reducing the manufacture cost of system and shorten construction period.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model cross section structure schematic representation.
Among the figure: 1-pipe lining, 2-seal ring, 3-cavity, 4-cutting ferrule, 5-U type lining, 6-stiffening rib.
Embodiment
Now, describe embodiment of the present utility model in detail in conjunction with Figure of description:
As shown be hard plastic pipe plug-in type connection pipe fitting, middle connection pipe fitting main body is pipe lining 1, and pipe lining 1 can be elbow, straight-through, threeway or four-way structure.The outside socket in each connecting port of pipe lining 1 is provided with cutting ferrule 4, pipe lining 1, cutting ferrule 4 cooperate by collar, the groove interlocking of relative set on two fitting surfaces, pipe between the adjacent cutting ferrule serves as a contrast and is equipped with stiffening rib 6 on 1 outer surface, to strengthen the intensity of described connection pipe fitting.Be configured for pegging graft between cutting ferrule 4 and the pipe lining 1 and wait to take over the cavity 3 of material, be equipped with U type lining 5 in the cavity 3, the thickness of U type lining 5 cavitys is slightly less than waits to take over the material diameter, when waiting to take over material and inserting and U type lining 5 close-fittings, the inner and outer surface of U type lining 5 is equipped with pointed tooth, waiting to take over the pointed tooth that material inserts back bush 5 inner and outer surface will corresponding incision pipe lining 1, material to be taken over, and will manage lining 1 and wait to take over the material location, prevent to wait to take over material axially displaced and with 1 disengagement of pipe lining.In the cavity 3 and U type lining 5 opening end positions are managed lining 1 outer surface accordingly, cutting ferrule 4 internal surfaces are respectively ramp structure, and described inclined-plane touches along side bumper with U type lining 5 opening ends respectively and cooperates, and prevent 5 displacements of U type lining.Pipe lining 1 connecting port outer surface is equipped with seal groove, and seal ring 2 is housed in the seal groove, waits to take over material insertion back pipe lining 1 and is tightly connected with waiting to take over the material formation by seal ring 2, and seal ring 2 adopts 0 shape seal ring.When install at the scene of using plug-in type connection pipe fitting described in the utility model to carry out hard tubing such as PEX aluminium-plastic composite pipe, only need to wait to take over material and directly insert the connection that just can realize in the cavity 3 between the pipeline, very convenient quick, and good sealing effect, phenomenons such as seepage can not take place.
