Abstract
The utility model relates to a nut clamping pipe fitting for PEX pipes, which belongs to the technical field of pipe fitting connection. The utility model solves the technical problem that a nut clamping pipe fitting for PEX pipes with the advantages of no required circle finishing and chamfering to connected pipe material ports in advance, no required seal ring insertion, good sealability and high connecting reliability is provided; therefore, 3-5 circular arc-shaped ribs and grooves which are arranged alternatively are arranged at the front part of a body; the middle part of the body is provided with a shaft shoulder with an oblique opening; the front part of a nut is sheathed with an oblique opening; the inner circular surface of a pressing ring is provided with 3-5 circular arc-shaped pressing ribs to realize the tight connection of the pressing ring, the connected pipe material and the body. The utility model is mainly used for the connection of PEX pipelines or other plastic pipelines and is especially suitable for pipeline connection in water supply and floor heating systems.
Description
Technical field
The utility model relates to pipe fitting interconnection technique field, the nut ferrule-type pipe fitting that especially a kind of PEX is effective.
Background technique
The effective pipe fitting of existing a kind of PEX is to adopt nut FERRULETYPE structure, and its critical piece is nut, retainer ring, body and seal ring.Earlier chamfering is carried out in the tubing end during installation, then nut is inserted in tubing, be inserted in retainer ring again, then tubing is inserted body portion, and two seal rings are to be contained in advance on the seal groove of body portion with instrument.Turn nut with spanner, make retainer ring simultaneously to axially and move radially, the retainer ring convex tendon on the annular side by side is pressed in the tubing, force tubing to produce plastic deformation, in the zigzag fashion groove on the inner plastic embedding body of tubing, simultaneously seal ring extrusion-deformation is produced certain decrement, thereby have anti-pulling performance and sealability.The shortcoming of this kind Placement is wanted the full circle chamfering by tubulature material port, in addition, influence owing to be subjected to assembler's dynamics to grasp institute when assembly, thereby its anti-pulling performance and sealability difference is bigger, influence the assembly quality.In addition, if installation method is incorrect, be easy to seal ring displacement distortion is caused seal failure.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of easy for installation, do not need in advance to be carried out the full circle chamfering to taking over the material end, not need the assembly seal ring and sealing is good again, connection reliability is high again the effective pipe fitting of nut FERRULETYPE PEX.
The technical solution that the utility model proposed is such: the effective pipe fitting of a kind of nut FERRULETYPE PEX, comprise body 21, nut 22 and retainer ring 23, nut 22 is connected with body 21 front threads, described body 21 front portions are provided with the circular arc convex tendon 215 and the circular groove 214 of 3-5 road interphase distribution, body 21 middle parts are provided with the shaft shoulder 216 of band angle 213, nut 22 front portions are provided with angle 211, retainer ring 23 inner headed faces are provided with 3-5 road circular arc beading 212, and described retainer ring 23 closely contacts with circular arc convex tendon 215 grooves 214 on the body 21 with the corresponding material of being taken over.The described shaft shoulder 216 is the scrobicular ring flute profile, and its external diameter is bigger slightly than being taken over the material external diameter.Described retainer ring 23 two end part are provided with the tilted conical surface of 25 ° of-35 ° of angles, are complementary with the angle 211 of nut 22 and the angle 213 on the body 21 respectively.
Compared with prior art, the utlity model has following beneficial effect:
(1) owing in the body that connects mutually, retainer ring, adopts the crimping structure of circular arc convex tendon and groove, thereby seal ring need not be installed, also just need not carry out the full circle chamfering during installation, both guarantee the sealing that connects, improved anti-pulling intensity, save man-hour again being taken over the material port.
(2) can avoid the leakage accident that takes place because of quality problems such as seal ring damages fully, improve and connect the reliability that part connects.
The utility model is mainly used in the connection of PEX pipeline or other plastic pipes, and the pipeline that is widely used in especially feeding water with in the floor heating system is connected.
Description of drawings
Fig. 1 is the structural representation of an embodiment's of the utility model the effective pipe fitting of a kind of nut FERRULETYPE PEX.
Fig. 2 is a pipe fitting decomposition texture schematic representation shown in Figure 1.
Embodiment
Referring to Fig. 1, shown in Figure 2, the effective pipe fitting of a kind of nut FERRULETYPE of present embodiment PEX is made up of body 21, nut 22 and retainer ring 23.Body 21 front portions are provided with alternate 3 circular arc convex tendons 215 and 3 circular grooves 214 of arranging, are used to hold the quilt that is out of shape behind the pressurized and take over material, to improve the anti-pulling performance and the sealability of assembly.Body 21 middle parts are provided with the shaft shoulder 216 that is used for tubing guiding and location, and these shaft shoulder 216 front ends are provided with the angle 213 that tapering is 30 ° of angles, be beneficial to retainer ring 23 can be simultaneously to axially and move radially.Screw thread the place ahead of nut 22 is provided with the angle 211 of 30 ° of angles, is beneficial to oppress moving of retainer ring 23.Retainer ring 23 two ends are equipped with the angle of 30 ° of angles, respectively with body 21 and nut 22 on the corresponding coupling of angle, simultaneously its inner headed face also is provided with the beading 212 of 3 circular arcs.Turn nut 22 with spanner during installation, because the effect of each 30 ° of angles, make retainer ring 23 can be simultaneously to axially and move radially, compressing is taken over the groove 214 of material on body 21 and is moved, force and taken over the material inwall and closely contact with groove 214 on the body 21, thus being tightly connected of realization pipe fitting, tubing.
The utility model can be used in combination with any end or straight-through, the elbow more than the end, tee pipe fitting.
