The utility model solves the technical scheme that its technical matters adopts: a kind of slip plug-in type ultrasonic flowmeter sensor, comprise base, valve, set collar, nut, potsherd and with the rodmeter of guard tube, described set collar and nut sleeve are contained on rodmeter, described base is welded on pipeline, described valve is twisted and is connected on base, described rodmeter is successively through heading into pipeline by potsherd after nut, set collar, guard tube, valve and base, and the surface of described rodmeter is smooth.
Further, also comprise steering yoke and scalable ring, described steering yoke is contained on rodmeter by scalable ring set.
Further, also comprise for tightening or unclamp the handle of valve.
Further, the front end of described rodmeter is provided with a probe, and the diameter of described probe head is greater than the internal diameter of rodmeter.
Further, also comprise the waterproofing work plastic jacket being sleeved on potsherd, described potsherd is fixedly connected with the inclined-plane of rodmeter front end by waterproofing work plastic jacket.
Further, the end of described rodmeter is also provided with waterproof wiring nut.
The beneficial effects of the utility model are: the surface of rodmeter is smooth, do not exist because impurity enters screw thread and cause the stuck phenomenon of rodmeter, rodmeter fixes by set collar and nut, during replacing, only need unclamp nut and set collar and just can take out rodmeter, change comparatively simply, and need to, at installation process multiturn rotational sensor bar, can not connect in advance sensor cable and seal, easily guarantee sealing effectiveness, more reliable; Rodmeter, with guard tube, prevents that medium from spraying when extracting rodmeter, safer.Further, comprise steering yoke and scalable ring, can regulate by steering yoke the direction of rodmeter, more intuitive and convenient.Further, the diameter of probe head is greater than the internal diameter of rodmeter, can guarantee that probe can be because the pressure in pipeline be compared with going out greatly, safer.

Embodiment
With reference to Fig. 1, a kind of slip plug-in type ultrasonic flowmeter sensor, comprise base 8, valve 1, set collar 7, nut 3, potsherd 9 and with the rodmeter 4 of guard tube 2, described set collar 7 and nut 3 are sleeved on rodmeter 4, described base 8 is welded on pipeline 12, described valve 1 is twisted and is connected on base 8, and described rodmeter 4 is successively through heading into pipeline 12 by potsherd 9 after nut 3, set collar 7, guard tube 2, valve 1 and base 8, and the surface of described rodmeter 4 is smooth.
Wherein, rodmeter, adopts smooth stainless iron Steel material to make, and its surface is smooth, has stopped to enter because of impurity the generation that screw thread causes rodmeter stuck phenomenon.
Set collar coordinates smooth rodmeter is fixed with nut.
Potsherd is tilted-putted ceramic sensor element sheet, for gathering the flow signal for the treatment of fluid measured.
On the tube wall of pipeline, have the bigger aperture of ratio sensor bar, make rodmeter potsherd can be headed into the inwall of pipeline.
