Summary of the invention
The problem that the utility model will solve provides a kind of high temperature flowmeter, solves the measuring problem of high-temperature medium flow.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of high temperature flowmeter; Comprise watch shell, be provided with gauge outfit, sensor stand successively on it; Sensor passes sensor stand and is connected with gauge outfit, and watch shell inside is provided with informing sheet, the fixedly Positioning Gear and the rotor wheel that is connected with informing sheet of informing sheet; Be provided with the metallic high temperature sealing ring between watch shell and the sensor stand; Informing sheet is located at the sensor lower end, and the informing sheet outer end is provided with the sheet tooth; Watch shell top is provided with U type sealing cap, and the one of which end is connected with sensor stand, and the other end is provided with to lower convexity; Sensor passes in the unsettled U of the being fixed on type of the sensor stand sealing cap.
Further, sensor lowermost end and watch shell distance topmost is less than U type sealing cap lowermost end and watch shell distance topmost.
Further, the distance of sensor lowermost end and U type sealing cap lowermost end is 1-2mm.
Further, sensor stand is the stainless steel right cylinder that the side is made up of the column that is uniformly distributed on the circumference of bottom surface.
Further, the sensor upper end is provided with lead-in wire, and the lower end is provided with magnet steel, and the magnet steel outside is with skeleton, and skeleton is provided with coil.
Further, the corresponding setting of sheet tooth of the magnet steel of sensor and informing sheet.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, the long-term operate as normal of sensor ability under high-temperature condition, the metering that has thoroughly solved the high-temperature medium flow.Have simple in structurely, processing cost is low, and is high temperature resistant, advantages such as long service life.

Embodiment
Like Fig. 1, shown in 2; The utility model provides a kind of high temperature flowmeter; Comprise watch shell 9, be provided with gauge outfit 1, sensor stand 2 successively on it; Sensor 4 passes sensor stand 2 and is connected with gauge outfit 1, and watch shell 9 inside are provided with informing sheet 5, the fixedly Positioning Gear 7 and the rotor wheel 6 that is connected with informing sheet 5 of informing sheet 5; Be provided with metallic high temperature sealing ring 10 between watch shell 9 and the sensor stand 2; Informing sheet 5 is located at sensor 4 lower ends, and informing sheet (5) outer end is provided with the sheet tooth; Watch shell 9 tops are provided with U type sealing cap 3, and the one of which end is connected with sensor stand 2, and the other end is provided with to lower convexity; Sensor 4 passes in the sensor stand 2 unsettled U of the being fixed on type sealing caps 3.
Sensor 4 lowermost ends and watch shell 9 distance topmost are less than U type sealing cap 3 lowermost ends and watch shell 9 distance topmost.
The distance of sensor 4 lowermost ends and U type sealing cap 3 lowermost ends is 1-2mm.
As shown in Figure 3, sensor stand 2 is stainless steel right cylinders that the side is made up of the column that is uniformly distributed on the circumference of bottom surface.
As shown in Figure 4, sensor 4 upper ends are provided with lead-in wire 11, and the lower end is provided with magnet steel 12, and magnet steel 12 outsides are with skeleton 14, and skeleton 14 is provided with coil 13.
The course of work of this instance: like Fig. 5, high-temperature medium 8 places in the container that watch shell 9 and U type sealing cap 3 constitute, and sensor 4 is positioned at U type sealing cap 3, with the distance of lowermost end be 1-2mm.Principle of work is cold air and hot-air convection radiating principle.
Informing sheet 5 is magnetic conductors, and during flowmeter work, rotor wheel 6 drives informing sheet 5 and rotates.When the sheet tooth of informing sheet 2 during over against the magnet steel 12 of sensor 4, it is logical to produce magnetic conductance, field weakening; When the tooth sky of informing sheet 2 during over against the magnet steel 12 of sensor 4, magnetic field strengthens.Because the variation in magnetic field strengthens or weakens, the electric current (or voltage) of coil 13 inductions also changes along with the cycle of informing sheet 5, becomes pulse ac with regard to the direct current that makes coil 13 like this.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
