Special isolation bag for anti-isolating fluid dilution steam metering

Abstract

The invention discloses an isolation bag special for steam metering and capable of preventing dilution of spacer fluid. The isolation bag comprises a spacer fluid filler, wherein a spacer fluid inlet for connecting a transmitter is formed in the lower end of the lateral surface of the spacer fluid filler. A funnel-shaped condensing water recoverer is arranged in the spacer fluid filler, and an outlet for connecting a steam pipeline is formed in the lower end of the recoverer. The isolation bag can thoroughly solve the problem that during steam metering, anti-freezing spacer fluid is diluted by steam condensation water, can greatly improve stability of a pressure guiding system, and solves the problem that in winter, the diluted spacer fluid is reduced in anti-freezing property and the pressure guiding system can be frozen.

Description

technical field [0001] The invention relates to a differential pressure flowmeter accessory, in particular to a special isolation package for measuring steam flow and steam pressure with a differential pressure flowmeter to prevent dilution of spacer fluid. Background technique [0002] When using a differential pressure flowmeter to measure steam flow or steam pressure, the pressure induction system should be filled with spacer fluid, and in the north, it should be filled with antifreeze spacer fluid. However, most antifreeze spacers are water-soluble, and are inevitably diluted by steam condensate during use, losing antifreeze performance, and generating additional differential pressure at the same time, causing measurement errors. This is the shortcoming of the traditional isolation package, and it is also a problem that the traditional isolation package cannot solve. [0003] In view of this, in view of the above problems, a special isolation package for anti-isolating ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a special isolation bag for anti-isolating liquid dilution steam measurement, which can completely solve the problem that the anti-freezing isolating liquid is diluted by steam condensed water during the steam measurement process, can greatly improve the stability of the pressure induction system, and at the same time solve the problem of Due to the dilution of the spacer fluid, the antifreeze performance of the spacer fluid is reduced, resulting in the problem of passive knots in the pressure induction system
