Description
Technical field
The utility model relates to a kind of vapour survey device, particularly a kind of high temperature diaphragm assembly.
Background technology
Referring to Fig. 1, traditional vapour survey method is by measuring the differential pressure of throttling element both sides, adopting Bernoulli equation calculation of steam flow then.Traditional vapour survey method comprises 3 parts:
1, the various throttling elements that can produce pressure differential illustrate by orifice plate in present patent application.
2, be used to measure 3 the electronic installation-differential pressures/Pressure/Temperature transmitter of differential pressure/Pressure/Temperature.
3, high-temperature steam is cooled to the condensing unit of differential pressure transmitter operation temperature area, illustrate by drainer in the present patent application.
With reference to Fig. 2, wherein because the existence of condensing unit, make the differential pressure type flow measurement of steam become indirect measurement method: because differential pressure transmitter actual be to measure steam to be condensed into the differential pressure behind the water rather than the differential pressure of open steam, so exist precision low/shortcoming that maintenance capacity is big, complexity is difficult to realize standardization and use split type three differential pressures/Pressure/Temperature transmitter that steam measurement system is seemed.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model purpose provides a kind of high temperature diaphragm assembly, and this assembly has improved measuring accuracy and reliability, realizes measuring multiple parameters, is convenient to on-the-spot Installation and Debugging.
A kind of high temperature diaphragm assembly described in the utility model, be provided with the pedestal of isolation diaphragm assembly in comprising, it is characterized in that: described isolation diaphragm assembly can weld or be sealed in the pedestal inner chamber by diaphragm gland and sealing gasket, in two pedestal inner chambers, isolation diaphragm is set respectively, the isolation diaphragm top is respectively arranged with kapillary, and described pedestal also is provided with the differential pressure transmitter mounting bracket.
Also be provided with tracting pressuring hole and exhaust tapping valve on the described pedestal, the diaphragm material of described high temperature diaphragm assembly can adopt 316 stainless steels as required respectively, breathes out the C alloy, tantalum etc.
Described two isolation diaphragms remain on the same plane by pedestal, and shape and size are symmetry equivalent fully.
Described pedestal is provided with the pressure transducer mounting hole, and filling liquid is protected differential pressure and two sensors of pressure simultaneously, gives two sensor passes pressure and reduces temperature.
The described temperature sensor mounting hole that has on pedestal because pedestal is operated in the high-temperature region, is convenient to measure the temperature of steam.
The utility model remarkable advantage:
1, measure used two barrier films size unanimity, settle on same plane, makes to measure more accurately and reliably.
2, Installation and Debugging are convenient, make that measurement is more accurate.
