Description

High temperature diaphragm assembly
Technical field
The present invention relates to a kind of vapour survey device, particularly a kind of high temperature diaphragm assembly.
Background technology
[0002] referring to Fig. 1, the prior steam measuring method is through measuring the differential pressure of throttling element both sides, adopting Bernoulli equation calculation of steam flow then.The prior steam measuring 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, cool to the condensing unit of differential pressure transmitter operation temperature area to high-temperature steam, 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 differential pressure rather than the differential pressure of open steam behind the water; So exist precision low/shortcoming that maintenance capacity is big, complicacy 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 the deficiency of above-mentioned prior art, the object of the invention 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 according to the invention; Be provided with the pedestal of isolation diaphragm assembly in comprising; It is characterized in that: said isolation diaphragm assembly can weld or be sealed in the pedestal inner chamber through 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 said pedestal also is provided with the differential pressure transmitter mounting bracket.
Also be provided with tracting pressuring hole and exhaust tapping valve on the said pedestal, the diaphragm material of said high temperature diaphragm assembly can adopt 316 stainless steels as required respectively, breathes out the C alloy, tantalum etc.
Said two isolation diaphragms remain on the same plane through pedestal, and shape and size are symmetry equivalent fully.
Said 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 said temperature sensor mounting hole that on pedestal, has because pedestal is operated in the high-temperature region, is convenient to measure the temperature of steam.
Remarkable advantage of the present invention:
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.

Embodiment
Combine Figure of description Fig. 3 to Fig. 5 to introduce high temperature diaphragm assembly embodiment according to the invention: to comprise pedestal 1, isolation diaphragm 3, diaphragm gland 2, sealing gasket 7, kapillary 5 at present; Be provided with isolation diaphragm 3 in the pedestal 1; Isolation diaphragm 3 can weld maybe and can be sealed in the pedestal inner chamber 8 through diaphragm gland 2 and sealing gasket 7; In two pedestal inner chambers 8, isolation diaphragm 3 is set respectively; Said isolation diaphragm 3 tops are respectively arranged with kapillary 5, and pedestal inner chamber 8 is connected through kapillary 5 and differential pressure transmitter 9 or multiparameter transmitter 14, and pours into silicone oil after in kapillary 5, vacuumizing; Transmit pressure and reduce temperature through silicone oil, thereby realize differential pressure measurement high-temperature medium.
With reference to Fig. 3, two isolation diaphragms 3 remain on the same plane through pedestal 1 in the high temperature diaphragm assembly according to the invention, and shape and size are symmetry equivalent fully.
With reference to Fig. 7, also be provided with tracting pressuring hole 20 and exhaust tapping valve 16 on the pedestal 1 according to the invention, tracting pressuring hole 20 keeps original measurement mounting means, and tracting pressuring hole 20 can connect waist flange, three valve sets 19, or directly takes the pressure that is threaded.
With reference to Fig. 1, Fig. 4; High temperature diaphragm assembly of the present invention fixes differential pressure transmitter 9 through mounting bracket 6; And through kapillary 5 and differential pressure transmitter 9 connections, and pour into silicone oil after in kapillary 5, vacuumizing, transmit pressure and reduce temperature through silicone oil; Thereby realize differential pressure measurement, changed the bulky disadvantage that is not easy to install of original like product high-temperature medium.
Said pedestal 1 is provided with pressure transducer mounting hole 10, and filling liquid is protected differential pressure pick-up and pressure transducer (not shown) simultaneously, to give said two kinds of sensor passes pressure and to reduce temperature.
On said pedestal 1, have temperature sensor mounting hole 21,, be convenient to measure the temperature of steam because pedestal 1 is arranged on the high-temperature region.
With reference to Fig. 2, Fig. 5; Pressure transducer (not shown) and temperature sensor 11 can be set on the high temperature diaphragm assembly of the present invention be combined into the incorporate multiparameter transmitter 14 of high temperature; Realize respectively the multiple parameters of differential pressure, pressure, temperature etc. is measured; Change original split type three differential pressures/Pressure/Temperature transmitter and be used for the traditional approach of the complicacy of vapour survey, thereby realized the standardization of vapour survey.
