Abstract
The utility model discloses a large-caliber aluminum-plastic pipe connection which is mainly composed of a connection body and a nut arranged around the connection body. A liner bushing is additionally arranged in the connection body and the liner bushing has a trapezoid sealing ring and an O-shaped sealing ring. The liner bushing has a pyramidal structure and has a circular conical surface at the root. A C-shaped snap ring is arranged on the end part of the connection body and the C-shaped snap ring is arranged in the nut. The utility model is suitable for the connection and installation of the aluminum-plastic pipes.
Description
Technical field
The utility model relates to a kind of aluminium plastic pipe joint, especially relates to a kind of heavy caliber aluminium plastic pipe joint.
Background technique
All use the plastic-aluminum pipe at present in industry, agricultural and people's daily row is lived, when this pipeline was installed, pipe joint was extremely important, the pipe joint kind that adopts on the market is a lot of now, mostly be to adopt fittings body to entangle composite pipe, fix, the way of seal ring sealing with nut.Structure is varied, is easily loosening but a significant disadvantages is arranged, and easily leaks the maintenance trouble.
Summary of the invention
The purpose of this utility model is to provide a kind of design more rational heavy caliber aluminium plastic pipe joint at the defective of aforementioned tube joint existence.
In order to achieve the above object, the utility model has mainly adopted following technological scheme to realize.The utility model mainly is made up of the fittings body of pipe joint and the nut of being located at outside the fittings body, the lining of in fittings body, also establishing, lining is provided with trapezoidal seal ring, also be provided with O-ring seals, lining is a cone structure, and its root is provided with conical surface, in the end of fittings body, also be provided with C shape snap ring, C shape snap ring also is placed in the nut.
The utility model compared with prior art has following tangible advantage.(1) the trapezoidal seal ring of sealed tube internal diameter is housed in lining, the sealing circle adopts the best silicone rubber of anti-permanent compression set to make, and the scholar that it can compensate the tubing plastics effectively becomes, thereby can keep excellent sealing performance enduringly.(2) the O shape that the radial seal effect also has been housed on lining is enclosed, and with the sealing surface of its seal cartridge and joint, this has just guaranteed not influence the sealing of joint when tubing causes axial dimension to change owing to expanding with heat and contract with cold from sealing configuration.(3) simple installation.Owing to insert the circular cone that the root of tubing end is shaped on one section 2-3mm * 30 ° on the lining, like this, the tubing that only needs when mounted to install lining is inserted into the fittings body bottom always, fastening nut gets final product again, need not as the external diameter sealed pipe fittings, must between bush end face and fittings body, reserve the gap of 2-3mm.
The utility model is applicable to the connection of plastic-aluminum pipe.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Accompanying drawing is the utility model overall structure cut-away view.
Embodiment
As shown in the figure, the utility model mainly is made up of the fittings body 2 of pipe joint and the nuts of being located at outside the fittings body 21, the lining of in fittings body 2, also establishing 3, lining 3 is provided with trapezoidal seal ring 7, also is provided with O-ring seals 4, and lining 3 is a cone structure, its root is provided with conical surface 5, in the end of fittings body 2, also be provided with C shape snap ring 6, C shape snap ring 6 also is placed in the nut.Tubing 8 is placed between fittings body 2 and the lining 3.
The utility model is applicable to the connection of plastic-aluminum pipe.
