Abstract
A water-supplying III-type polypropylene pipeline telescopic loose joint comprises a loose joint body; one end of the loose joint body is provided with a metal insert with screw thread, or is directly welded with a plastic pipe in a hot melt way; the other end is provided with a seal groove; the loose joint body is oil cylinder shape. The utility model has high construction efficiency, good sealing performances, beautiful appearance, and can effectively solve changes of plastic axial length caused by temperature changes of the plastic pipe; the utility model can not result in deformation of the plastic pipe.
Description
The utility model belongs to the plastic conduit link, specifically refers to the flexible flexible joint of polypropylene pipe.
At present, adopt " L " type or " Ω " type expansion bend to carry out the nature compensation usually, in particular cases also adopt the corrugated stainless steel tubing expansion loop, regulate axially expanding with heat and contract with cold of feedwater PP-R pipe.This flexible compensation device, not only construction and installation complexity, required installing space is big, and outward appearance is indecency.
The purpose of this utility model provides a kind of compact conformation, the flexible flexible joint of plastic conduit easy for installation, safe and reliable, long service life.
The purpose of this utility model takes following technical scheme to realize:
The utility model is to use for reference hydraulic actuating mechanism---the principle of oil cylinder, at joint (main body) end metal insert is set, and other end inwall is provided with at least one special groove that sealing ring is housed, and is able to positiver sealing under the dual extruding of machinery and liquid.The feedwater of flexible joint correct position of packing into is managed with three type polypropylene (PP-R), along with the variation of water temperature and natural temperature, is axially freely stretching, thereby is avoiding the outward appearance distortion, has played compensating action.
Another program of utility model is, main body one end and plastic pipe sweat soldering, and other end inwall is provided with at least one special groove that sealing ring is housed.
Structure design of the present utility model compared with prior art has outstanding advantage: the utility model compact conformation, and easy for installation, good seal performance, safe and reliable; Compare with existing flexible compensation device, omitted members such as elbow, sliding support, omitted part hot melt operation, improved efficiency of construction, reduced cost; Good looking appearance.
Specific embodiments of the present utility model is as shown in drawings:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the structural representation of another embodiment
Concrete structure and embodiment below in conjunction with accompanying drawing elaborate to the utility model:
Among the figure: 1. main body 2. sealing rings 3. grooves 4. metal inserts 5. external screw thread plastic pipes 6. plastic pipes
Embodiment shown in 1 with reference to the accompanying drawings:
Feedwater is the cylinder type tubular structure with the stretch main body 1 of flexible joint of three type polypropylene pipes, and by three type polypropylene, or material such as ABS is made.Main body 1 one ends are provided with metal insert 4, offer internal thread in the metal insert 4, with external screw thread plastic pipe 5 thread connection; Other end inwall is offered groove 3, groove 3 built-in rings 2.The quantity of groove 3 can be offered one or more according to need of work, and sealing ring 2 also can use one or several.Plastic pipe 6 is packed in the main body 1.
Embodiment shown in 2 with reference to the accompanying drawings:
Main body 1 one ends and plastic pipe 6 sweat solderings; Other end inwall is offered groove 3, and another plastic pipe 6 is packed in the main body 1.A same embodiment of all the other structures.
The utility model can design makes plurality of specifications, respectively with diameter 12mm～160mm between the use that matches of the tubing of plurality of specifications.
