Abstract
The invention discloses a thermowell. The thermowell comprises a tube body, wherein a thermometer installation hole is formed inside the tube body, the outer wall of the tube body is oval, the thermometer installation hole is round, the axis of the thermometer installation hole is parallel to the axis of the tube body, and the axis of the thermometer installation hole is deviated from the axis of the tube body. The thermowell has the advantages that when an oval long-axis portion of the tube body right faces the flowing direction of fluid, the change of a flow field is quite little after the fluid flows through the thermowell, and compared with a cylindrical thermowell, the thermowell generates no eddy; in addition, due to the fact that a temperature measurement component is arranged eccentrically, compared with a thermowell of a symmetrical structure, the thermowell of the eccentric structure has the advantages that the change of the inherent frequency of the thermowell is larger relative to the that the central position of the symmetrical thermowell, and the resonance caused by the identical frequency between the thermowell and the fluid is reduced to a great extent.
Description
Technical field
The present invention relates to temperature element sleeve pipe, applicable commercial measurement bimetallic system cell, thermopair, thermal resistance.
Background technology
The thermo detector sleeve pipe that chemical industry adopts conventionally is at present in chemical process temperature survey, under the effect of process fluid, be immersed in sleeve pipe in fluid because vortex shedding can produce vibration, when vibration frequency approaches the natural frequency of sleeve pipe, may resonate, the stress that causes fluid to act on sleeve pipe surpasses the bearing the limit of sleeve pipe and sleeve pipe is fractureed, produce and leak, and make to be inserted in the detector unit damage in sleeve pipe, and affect temperature survey, even have an accident.
Summary of the invention
The object of the invention is to overcome the deficiency of prior art, a kind of difficult generation resonance is provided, is difficult for a kind of thermometer boss of breaking and fractureing.
A kind of thermometer boss of the present invention, it comprises body, in described body inside, has thermometer mounting hole, and described tube wall is oval, described thermometer mounting hole is circular, and the biasing setting parallel with body axis of the axis of described thermometer mounting hole.
Advantage of the present invention:
When the oval major axis part of body is over against direction of flow, fluid is before and after process sleeve pipe, flow field changes very little, with respect to cylindrical sleeve, can not produce eddy current, and temperature element is in eccentric position, with respect to the sleeve pipe of symmetrical structure, the sleeve pipe of eccentric form self natural frequency changes greatly with respect to symmetrical center, has largely reduced resonance consistent with fluid frequency and that produce.
Accompanying drawing explanation
Fig. 1 is the scheme of installation of a kind of thermometer boss of the present invention;
Fig. 2 is the vertical view of the thermometer boss shown in Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
A kind of thermometer boss of the present invention as shown in drawings, it comprises body 1, in described body inside, has thermometer mounting hole 2, and described tube wall is oval, described thermometer mounting hole is circular, and the biasing setting parallel with body axis of the axis of described thermometer mounting hole.
The axis of preferred described thermometer mounting hole is positioned at the vertical plane at the major axis place of oval tube wall.
The using method of this device is as follows: in the thermometer mounting hole 2 that temperature element 3 inserts in body 1.Thermometer boss mounting means can be selected according to operating mode, as mounting meanss such as flange form, welding, screw-types.
Figure 1 shows that flange form installation, i.e. body and flange 4 welding processing.Then flange 4 and the flange 5 for the treatment of temperature measuring equipment are fixedly linked by bolt etc., now the oval major axis of body partly will, over against direction of flow, insert temperature measuring equipment by body and can convection cell temperature measure.
Claims (2)
1. a thermometer boss, it comprises body, in described body inside, has thermometer mounting hole, it is characterized in that: described tube wall is for oval, described thermometer mounting hole is circular, and the biasing setting parallel with body axis of the axis of described thermometer mounting hole.
2. thermometer boss according to claim 1, is characterized in that: the axis of described thermometer mounting hole is positioned at the vertical plane at the major axis place of oval tube wall.
