The utility model relates to a kind of pipe connecting component, specifically refers to a kind of internal thread pressing type pipe fitting connecting piece for hot and cold water thin walled tube.
background technique
At present, on market, there is multiple pipe connecting component, especially supply the pipe connecting component of cool and hot water pipe, especially the link of thin walled tube generally all adopts pressure-cliping or is welded to connect, but there is connection sealing, pulling capacity, resistance to powerful poor problem: as, cartridge connection compression resistance torsion, pulling capacity are inadequate, and the anti-power of expanding with heat and contract with cold is inadequate; And welding type connects the fastening but pollutant of surfacing, as difficult processing such as scolder, deadlocked things, and connection difficulty is large.Because the mechanical strength of using above-mentioned structure and Placement to make link is good not, the shortcoming that sealing is poor.
model utility content
The technical problems to be solved in the utility model is to provide a kind of internal thread pressing type pipe fitting connecting piece, effectively raises mechanical strength and sealability.
[0004] for solving the problems of the technologies described above, the technical solution adopted in the utility model is: internal thread pressing type pipe fitting connecting piece comprises the first pipe fitting, the second pipe fitting, interior plug screw, promote pad, snap ring and seal washer, above-mentioned the first pipe fitting outer wall is provided with annular recess, interior plug screw is sheathed on the first pipe fitting, the outer wall of the first pipe fitting is sheathed seal washer and promotion pad also, above-mentioned interior plug screw is provided with outside thread, the inwall of interior plug screw has annular ridge, the second pipe fitting inner wall arranges internal thread, promotion pad is sheathed on the first pipe fitting, and promote the side that shim pack is loaded on the first pipe fitting annular recess, then by sheathed the first pipe fitting of seal washer, and promote the same side that pad and seal washer are all positioned at the first pipe fitting annular recess, snap ring is sheathed on the annular recess of the first pipe fitting outer wall, then interior plug screw is penetrated from the other end of the first pipe fitting, one end of the first pipe fitting is stretched in the second pipe fitting, finally the logical interior outside thread of plug screw and the internal thread of the second pipe fitting are spirally connected and further promote snap ring and promote pad, promote pad and promote seal washer and the integral body that sealing is good of the second pipe fitting close contact composition.
Preferably, the second pipe fitting can be three-way pipe, four-way pipe or reducer, is applicable to the connection of different tube diameters or multi-pipeline, and the second pipe fitting and seal washer front end contacting part are conical surface.
Preferably, the cross section of seal washer is right-angled trapezium.
Preferably, interior plug screw is engineering plastics tightening nut, and interior plug screw arranges spanner away from the externally threaded one end of interior plug screw and opens groove.
Preferably, the first pipe fitting, the second pipe fitting, promotion pad and interior plug screw all adopt stainless steel material, do not need welding, and corrosion resistance is strong, does not affect water quality, is not also subject to water quality impact.
Relative to existing technologies, its beneficial effect is the utility model: the utlity model has that mechanical strength is high, good airproof performance, pulling capacity by force, not polluted water and the simple advantage of connection.
