Description
Technical field
The utility model is related to a kind of pipe's flow parameter measurement apparatus, belongs to thermal physical property parameter testing field.
Background technology
The characteristic of working medium Bottomhole pressure be always in the research focus of various countries researcher, working medium tube flow behavior include pass
Heat, flow resistance etc..For flow behavior this block research and design to fluid parameter measurement, temperature be fluid important parameter it
One, the measurement for fluid temperature (F.T.) at present typically uses thermocouple, must thus go deep into thermocouple to pipeline, so
The sealing problem of pipeline is there is, its sealing is more difficult to when in pipe being high-pressure fluid.
Utility model content
The purpose of this utility model is to be directed to technological deficiency present in prior art, and provides temperature test in a kind of pipe
Device.
To realize that the technical scheme that the purpose of this utility model is used is：
Temperature testing device in pipe, it is characterised in that described device includes test pipe, external screw thread base, internal thread sodium
Son, thermocouple, tetrafluoro sleeve pipe, the external screw thread base are welded on the position of opening of test pipe, outside the external screw thread base
Side face top is external screw thread, and the tetrafluoro casing part is cylinder, and tetrafluoro sleeve pipe top is cone, internal thread sodium
Bottom surface is outer-hexagonal shape, and internal thread sodium madial wall bottom is internal thread, and internal thread sodium inner upper is cone, described interior
Screw thread sodium top inner circumferential and tetrafluoro sleeve pipe upper periphery screw thread coordinate, the tetrafluoro casing part cylindrical part periphery with it is outer
Screw thread base internal whorl coordinates, and the external screw thread base, internal thread sodium, tetrafluoro sleeve pipe are respectively provided with thermocouple wire perforation, institute
Internal thread sodium is stated to seal using wlding after thermocouple wire is passed.
Compared with existing experimental provision, the beneficial effects of the utility model are：
1st, this experiment is simple to operate using thread seal.
2nd, the unique structure design of all parts enables to it to have higher pressure-resistant performance.
Brief description of the drawings
Fig. 1 show temperature testing device structure chart in the utility model pipe.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in figure 1, temperature testing device includes test pipe 1, external screw thread base 5, internal thread sodium 2, thermoelectricity in pipe
Even 3, tetrafluoro sleeve pipe 4, the external screw thread base 5 is welded on the position of opening of test pipe 1, the periphery of external screw thread base 5
Face top is external screw thread, and the bottom of tetrafluoro sleeve pipe 4 is cylinder, and the top of tetrafluoro sleeve pipe 4 is cone, internal thread sodium
2 bottom surfaces are outer-hexagonal shape, and the madial wall bottom of internal thread sodium 2 is internal thread, and the inner upper of internal thread sodium 2 is cone, institute
State the top inner circumferential of internal thread sodium 2 with the upper periphery screw thread of tetrafluoro sleeve pipe 4 to coordinate, the lower cylindrical portion of tetrafluoro sleeve pipe 4
Periphery coordinates with the internal whorl of external screw thread base 5, and the external screw thread base 5, internal thread sodium 2, tetrafluoro sleeve pipe 4 are respectively provided with thermoelectricity
Amphitene is perforated, so as to passing for thermocouple wire, and internal thread sodium is sealed after thermocouple wire is passed using wlding.
The external screw thread base 5 is welded on the testing tube 1 of perforate, and the tetrafluoro sleeve pipe 4 is placed in the male-pipe 5
In portion's groove, the top of tetrafluoro sleeve pipe 4 preferably coordinates with the inside of internal thread sodium 2, internal thread sodium 2 and institute
State external screw thread base 5 and fitted seal is carried out by MF, when internal thread sodium 2 is down twisted, the top of tetrafluoro sleeve pipe 4
Contacted with the inner tight of internal thread sodium 2 extruding, at the same the thermocouple string holes inside tetrafluoro sleeve pipe 4 is more crowded smaller, directly
To being not present gap, it is to be tightened after the top thermocouple hole of internal thread sodium 2 is sealed using wlding, therefore have dual close
Temperature testing device is easy to make in envelope, the pipe and has good sealing.
Described above is only preferred embodiment of the present utility model, it is noted that for the general of the art
For logical technical staff, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these change
Enter and retouch and also should be regarded as protection domain of the present utility model.
