Cold rotation compacting means 9 are set to inside screw thread water outlet mouthpiece 7；
The cold rotation compacting means 9 of thermal expansion closely enclose 93 by cold water stream penetrating mechanism 91, expanding mechanism 92, thermal expansion and form,
The cold water stream penetrating mechanism 91 is set to 92 inside of expanding mechanism and engagement is flexibly connected, and the thermal expansion closely encloses 93 and is set to expansion
It 92 outer surface of mechanism and is fitted and connected by face and face.
The cold water stream penetrating mechanism 91 encloses 911, water flow stressed plate 912, ejection grain 913,914 groups of extension spring by rotation
At the water flow stressed plate 912 is uniformly equidistant to be set to inside rotation circle 911, and the ejection grain 913 is set to rotation 911 appearances of circle
Face and perpendicular shape is connected, the extension spring 914 are set to the side clockwise of ejection grain 913,914 liang of the extension spring
It is welded respectively with ejection grain 913 and expanding mechanism 92 at end.
The water flow stressed plate 912 is equipped with 8-12 piece, oblique uniformly equidistant inside rotation circle 911, described
Water flow stressed plate 912 is in tilt along chilled water flow direction, realizes and pushes water flow stressed plate 912 using flow force and drive rotation
911 rotation of circle, provides driving force for expansion.
The ejection grain 913 is equipped with 4 and uniformly equidistant be set to rotates 911 outer surfaces of circle, and 913 outer end of ejection grain is in
Arc smooth structure engages flexible connection with expanding mechanism 92, realizes effectively sliding, prevents its sliding of friction effects.

The side clockwise of arc groove 922, the connecting spring 924 are set between arc expansion item 921 and arc expansion item 921 and logical
Electric welding is crossed to be connected.
Arc expansion item 921 is equipped with 4, and a combination thereof forms radius and closely encloses the identical ring junction of 93 internal diameters with thermal expansion
Structure, realization can freely expand receipts and ejection thermal expansion closely encloses 93, guarantee that thermal expansion closely encloses the compactness of 93 outer walls, prevent leak.
The arc groove 922 is deeper in recess clockwise, ejection grain 913 in 922 internal slide of arc groove,
Realize that expanding item 921 by the depth ejection arc of groove extends out.
Working principle of the present invention is as follows: hot-water line is connected by hot water connector 3 with hot water inlet pipe 2, by cold water
Pipe is connected by cold water connector 6 with cold water inlet pipe 5, and outlet pipe and screw thread water outlet mouthpiece 7 are connected；If connecing at this time
Enter hot water, thermal expansion closely encloses 93 meeting expanded by heating, and outer surface can be close to the gap of water outlet mouthpiece, prevent its interface leak；If
It is access is cold water, the water flow of cold water will push that water flow stressed plate 912 is mobile, water flow stressed plate 912 is to drive rotation to enclose
911 rotation, at this time ejection grain 913 along arc groove 922 slide, from the depths of arc groove 922 be moved to it is shallow from, arc
Expansion item 921 then will receive ejection force and expand outwardly, and thermal expansion is closely enclosed to 93 outside ejections, its outer surface is made to be close to water outlet mouthpiece
Gap, can equally prevent interface leak, when again switch to hot water when, extension spring 914 can pull ejection grain 913 drive rotation
Circle 911 returns to original state, while the arc for expanding shape expands item 921 also under the action of connecting spring 924, and shrinking is in original state.
Problems solved by the invention is the temperature Chang Chengleng of the water outlet of the dual flow path metal pipe joint of the prior art
Hot checker, if the gap when rubber ring thickness added at interface gap compensates exactly for out cold water, then in hot water out
When, expanded by heating can occur, ejection gap makes gap become larger, when again go out cold water when, can leak due to gap is larger,
Or rubber ring is squeezed by transition and loses deformability, thoroughly loses close effect；And if the rubber added at interface gap
Cushion rubber thickness compensates exactly for out gap when hot water, can not play the role of in cold water out it is close, the present invention pass through above-mentioned component
Be combined with each other, by the cold water stream penetrating mechanism being equipped with, can in cold water out, through the thrust ejection rubber ring of water flow,
It expands it and is close to the gap of water outlet mouthpiece, prevent it from leak occurs in cold water out；It is closely enclosed by the thermal expansion being equipped with, it can
Using the characteristic of rubber thermal expansion, to compensate the gap of water outlet mouthpiece, leak occur when preventing it from going out hot water in hot water out, solution
Certainly the rubber ring inside connector is in hot and cold water out, because volume changes with temperature, and can only closely go out hot water or cold out
The problem of gap when water, realize that the compactness of connector will not change with temperature.
