Description
Technical field
The utility model relates to a kind of pipe fitting, relates in particular to a kind of pipe fitting that flexible pipe is used that connects.
Background technique
Traditional connection pipe fitting is adopted in the connection of flexible pipes such as PEX pipe, aluminium-plastic composite pipe, connects very easily to get loose, thereby causes seepage.There is kind of solution to adopt at present and sealed groove is set, wedge shape sealing ring is housed on groove on the surface, pipe belled part of fittings body.This pipe fitting is connected with composite pipe by nut, complex structure, and construction and installation are loaded down with trivial details, use inconvenience.Another kind of solution is also arranged; it has the body of connection, core pipe, hold-down ring, seal ring, nut; through hole is arranged in the joint body; connecting end has the outside thread that cooperates with nut; be provided with the inner cone nipple orifice at an end that matches with nut; step is arranged in the joint body; be used to install aluminium-plastic composite pipe and other similar body; the core pipe is the metal thin-wall sleeve pipe; insert composite pipe connecting end inwall during connection; hold-down ring is a metal spring, is sleeved in the inner cone nipple orifice of band protecting jacket, and the structural complexity of this pipe fitting is conspicuous.Also have a kind of solution to adopt the pressurization ways of connecting, it by fittings body, tighten up steel bushing and form, the rear end, pipe belled part of fittings body is provided with axial notch, the connecting end of fittings body is straight tube shape, the connecting end outer surface also is provided with annular groove, sheathed elastic rubber sealing ring in the annular groove.This compact structure, connect reliable, but the axial notch processed complex of fittings body, manufacturability is bad.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of process simple, have higher anti-drawing ability and more reliable sealing effect, an anti-electrocorrosion and can prevent that tubing and pipe fitting are in relative rotation with the clamp-press type pipe of protecting jacket.For this reason; the utility model is by the following technical solutions: it comprises fittings body and chucking cover; the connecting end of fittings body is straight tube shape; the connecting end outer surface is provided with many ring-type pawls; connecting end appearance and also be provided with annular groove; the interior sheathed elastic rubber sealing ring of annular groove, the rear end, pipe belled part of described fittings body is provided with protecting jacket, and the internal surface of protecting jacket is provided with to make and forms the circular step of front axle to the axial groove of groove and back in the protecting jacket.
The utility model also can adopt following further technological scheme simultaneously:
Described protecting jacket is made of plastics.
Also be provided with stop ring in the zone that the ring-type pawl is set of described fittings body, stop ring is provided with rotation inhibiting and rolls tooth.
Described stop ring is located at the rear portion of annular groove.
The utility model is provided with two annular grooves, and stop ring is located between two annular grooves.
Whether the proximal end of chucking cover is provided with peep hole, put in place so that observe the tubing insertion.
The utility model adopts the pressurization ways of connecting, by the personality card press tool chucking cover is applied enough clamping forces and makes it produce nonvolatil plastic deformation, is connected thereby tubing is reached with pipe fitting.Be provided with the protecting jacket of band shape boss in the rear end, pipe belled part of fittings body, can make things convenient for the installing and locating of protecting jacket, make the utility model processing simple, make again install and use convenient.Adopt the protecting jacket of plastics, can prevent the electro erosion between the different metal.Front end at fittings body is provided with stop ring, the flexible pipe inner wall section is clamp-oned on the pawl of connecting end and the stop ring rolled in the tooth, has higher anti-drawing ability, prevents relatively rotating of tubing and pipe fitting simultaneously effectively.
