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. An axial groove is arranged on the rear end of the pipe sheathing part of the joint body. A plurality of annular reverse teeth are arranged on the outer surface of the connecting end of the joint body. 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 stop ring is also arranged on the outer surface of the connecting end of the joint body, 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 causes the connection of pipe materials to have higher drawing resistant capability and more reliable sealing effect; meanwhile, the relative rotation of the pipe materials and pipe fittings 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 applicant's utility model patent ZL99215361.1 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 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.Its compact structure, connection are reliably.
The purpose of this utility model is to provide a kind of have higher anti-drawing ability and reliable sealing effect and can prevent tubing and pipe fitting clamp-press type pipe in relative rotation more.
The technical solution of the utility model is:
A kind of clamp-press type pipe, form by fittings body, chucking cover, 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 several annular grooves, sheathed elastic rubber sealing ring in the annular groove, also be provided with stop ring on the connecting end outer surface of described fittings body, have rotation inhibiting to roll tooth on the stop ring.
Described stop ring is located at the rear portion of annular groove.
In the axial notch of the rear end, pipe belled part of fittings body spacer ring is housed.
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 stop ring, the flexible pipe inner wall section clamp-oned on the pawl of connecting end and the stop ring rolled in the tooth, have higher anti-drawing ability, prevent relatively rotating of tubing and pipe fitting simultaneously effectively.In the axial notch of fittings body, spacer ring is housed, sealing effect is further improved, and prevent the electro erosion of different metal.
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 decomposing schematic representation of the utility model structure.
A kind of clamp-press type pipe, form by fittings body 1, chucking cover 7, the rear end, pipe belled part of fittings body 1 is provided with axial notch 9, spacer ring 2 is housed in the axial notch 9, and the connecting end of fittings body 1 is straight tube shape, and the connecting end outer surface is provided with many ring-type pawls 3, the connecting end outer surface also is provided with several annular grooves 6, sheathed elastic rubber sealing ring 4 in the annular groove 6 also is provided with stop ring 5 on the described fittings body connecting end outer surface, and stop ring 5 is provided with rotation inhibiting and rolls tooth.
General pipe fitting connecting end outer surface is provided with two annular grooves 6, and stop ring 5 is located at the intermediate portion of two annular grooves 6.
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 4 and spacer ring 2 earlier, chucking cover 7 is enclosed within on the flexible pipe 8 that matches, directly insert the connecting end of fittings body 1, will tighten cover 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.
