Abstract
The utility model discloses a clamping and pressing type pipe fitting which is used for the connection of flexible pipes. The clamping and pressing type pipe fitting which is used for the connection of flexible pipes is composed of a joint body and a clamping sleeve. A plurality of annular reverse teeth are arranged on the outer surface of a connecting end, an annular groove is also arranged on the outer surface of the connecting end, and an elastic rubber sealing ring is sheathed in the annular groove. A protective sleeve with an axial groove is arranged on the read end of the pipe sheathing part of the joint body, a stop ring is also arranged on the outer surface of the connecting end, and a rolling tooth for preventing rotation is arranged on the stop ring. The clamping and pressing type pipe fitting which is used for the connection of flexible pipes of the utility model has simple processing, the connection of the clamping and pressing type pipe fitting which is used for the connection of flexible pipes and pipe materials has higher drawing resistant capability and galvanic corrosion resistance, and the relative rotation of the clamping and pressing type pipe fitting which is used for the connection of flexible pipes and the pipe materials is prevented.
Description
The utility model relates to a kind of pipe fitting, especially relates to the pipe fitting that a kind of flexible pipe connects usefulness.
The connection of flexible pipes such as PEX pipe, aluminium-plastic composite pipe is adopted traditional pipe fitting to connect and is very easily got loose, and the seepage phenomenon takes place.China utility model patent ZL98234174.1 discloses a kind of aluminium-plastic composite pipe pipe joint, form by joint body, nut, hold-down ring, joint body comprises nut portions, screw section and pipe belled part, the surface, pipe belled part of pipe joint is provided with sealed groove, and on groove wedge shape sealing ring is housed.This pipe joint is connected with composite pipe by nut, complex structure, and construction and installation are loaded down with trivial details, use inconvenience.
China utility model patent ZL98226427.5 discloses a kind of connecting head of aluminium-plastic composite pipe.Structure has this head of connection, core pipe, hold-down ring, seal ring, overcoat (nut) formation, through hole is arranged in the joint body, one end has outside thread, the other end has outside thread to cooperate with overcoat, be provided with the joint internal taper hole at an end that matches with overcoat, step is arranged in the joint body, be used to install aluminium-plastic composite pipe and other similar bodys, 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 joint internal taper hole, overcoat is a kind of nut, has internal thread and matches with the joint body outside thread.
The utility model patent ZL99215361.1 that the applicant has discloses a kind of pipe joint link, adopt the pressurization ways of connecting, the pipe joint link 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 is provided with many ring-type pawls, and the connecting end outer surface also is provided with annular groove, sheathed elastic rubber sealing ring in the annular groove.Its compact structure, connect reliable, but the axial notch processed complex of fittings body, manufacturability is bad.
The purpose of this utility model be to 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.
The technical solution of the utility model is:
A kind of clamp-press type pipe with protecting jacket; form by fittings body, chucking cover; the connecting end of fittings body is straight tube shape; the connecting end outer surface is provided with many ring-type pawls; the connecting end outer surface also is provided with annular groove; sheathed elastic rubber sealing ring in the annular groove, the rear end, pipe belled part of described fittings body is provided with the protecting jacket that has axial notch.Described protecting jacket is made of plastics.
Also be provided with stop ring on the described fittings body connecting end outer surface, have rotation inhibiting to roll tooth on the stop ring.
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.Rear end, pipe belled part at fittings body is provided with the protecting jacket that has axial notch, makes fittings body process simply, 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.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is a structure sectional view of the present utility model;
Fig. 2 is the partial enlarged drawing at A place among Fig. 1;
Fig. 3 is the decomposing schematic representation of the utility model structure.
A kind of clamp-press type pipe with protecting jacket; form by fittings body 1, chucking cover 4; the connecting end of fittings body 1 is straight tube shape; the connecting end outer surface is provided with many ring-type pawls 5; the connecting end outer surface also is provided with annular groove 6; sheathed elastic rubber sealing ring 2 in the annular groove 6, the rear end, pipe belled part of fittings body 1 is provided with the protecting jacket 3 that has axial notch 9.Protecting jacket 3 can be made of plastics.
Described annular groove 6 rear portions also are provided with stop ring 7, have rotation inhibiting to roll tooth on the stop ring 7.
The utility model can be applicable to any end or the above above demultplexer joint of straight joint, elbow connection, three-way union, threeway that connects flexible pipe of an end or the like pipe fitting.
During installation; install elastic rubber sealing ring 2 and protecting jacket 3 earlier, in the axial notch 9 of protecting jacket 3, knock in the chucking cover 4 that matches with wooden mallet again, circle back, flexible pipe 8 enlarging schools is inserted in the chucking cover 4 with mouth expander; to tighten cover 4 with special-purpose card pressing tongs at last and compress ne-leakage phenomenon during pressure testing.
The utility model is applicable to the connection of flexible pipes such as PEX pipe, aluminium-plastic composite pipe.
