Abstract
The utility model relates to a pipe joint for plastic composite pipe fittings, which is composed of inner metal linings, outer metal linings, metal sleeve seats and a plastic sealing ring. The utility model is characterized in that two inner metal linings are respectively sheathed in ports of pipe fittings requiring connection; two outer metal linings are respectively sheathed out of the pipe fittings requiring connection; two metal sleeve seats are respectively sheathed on the two outer metal linings; in addition, a coupling nut is fixed with the metal sleeve seats; the plastic sealing ring is sheathed at the joint of the ports of the pipe fittings requiring connection. Because the utility model does not need to be fixed by threads, the compression strength of the utility model is high; the sealing ring is used, the sealing performance is good; the utility model has the advantages of simple installation and convenient disassembly.
Description
Technical field
The utility model belongs to a kind of pipe joint, is a kind of plastic composite pipe pipe joint specifically.
Background technique
In construction industry, adopt plastic composite pipes at present in a large number, when installing, pipe fitting needs between the tube and tube to connect, as threeway, four-way, elbow etc., existing method commonly used is to adopt to be threaded, and adopts the shortcoming that is threaded and exists system thread head difficulty and voltage endurance capability to descend on plastic tube.The disclosed patent No. of Patent Office is 98219742.X and 98243059.0 patents, be not threaded though they adopt, but still exist can not be for convenience detach after installing the defective that is not easy to overhaul.
Summary of the invention
The purpose of this utility model provides a kind of good seal performance, compressive strength height, simple plastic composite pipe pipe joint is installed, to overcome above-mentioned deficiency.
To achieve these goals, the utility model is made of interior metal lining, outer metal lining, metal block set, plastic seal ring, be characterized in: two interior metal linings are inserted in respectively and need in the connection pipe fitting port, two outer metal linings are enclosed within respectively and need outside the connection pipe fitting port, two metal block sets are enclosed within respectively on two outer metal linings, also have a coupling nut and metal block set to fix, plastic seal ring is enclosed within the junction point that needs the connection pipe fitting port.
The utility model makes and adopts seal ring by the utility model compressive strength height owing to fix without screw thread, makes that good seal performance, the utility model are installed simply, convenient disassembly.
Description of drawings
Accompanying drawing is the utility model structural representation.
Among the figure:
Metal lining, the outer metal lining of 3-, 4-one end metal block set, 5-plastic seal ring, 6-metal coupling nut, 7-the other end metal block set in 1-steel-plastic composite pipe, the 2-.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing.
The utility model is made of interior metal lining 2, outer metal lining 3, metal block set 4,7, plastic seal ring 5, two interior metal linings 2 are inserted in respectively and need to connect in composite steel-plastic pipe fitting 1 port, two outer metal linings 3 are enclosed within respectively and need to connect outside composite steel-plastic pipe fitting 1 port, two metal block sets 4,7 are enclosed within respectively on two outer metal linings 3, also have a coupling nut 6 fixing with metal block set 4,7, plastic seal ring 5 is enclosed within the junction point that needs to connect composite steel-plastic pipe fitting 1 port.
The effect of metal lining 2 prevents steel-plastic composite pipe 1 distortion on the one hand in the utility model, increases pipe location stiffness on the other hand; The effect of outer metal lining 3 prevents steel-plastic composite pipe 1 distortion, reinforcement tube location stiffness on the other hand on the one hand; The effect of one end metal block set 4 is with steel-plastic composite pipe 1 distortion location; The effect of plastic seal ring 5 prevents that steel-plastic composite pipe from connecting the back and leaking; The effect of metal coupling nut 6 connects the location with two end metal block sets; The effect of the other end metal block set 7 is with steel-plastic composite pipe distortion location.
