Automatic control split-stream sampling difference reading type heat value meter

Abstract

An automatic control shunt sample difference thermal value flowmeter relates to the automatic measurement to indoor heat value of hot-water circulation pipeline, which utilizes the running water meter measurement way to convert the complicated water-carried radiated hot-water heat value test to two-meter difference hot-water flow measurement, not using foreign power to control and start the heat value meter.

Description

Technical field [0001] The present invention is a self-control shunt sampling and difference-reading calorific value meter, which relates to the automatic metering of the heating calorific value emitted by the water heating circulation pipeline in the user's room, without external power, and using the reliable and long-used tap water meter metering method to convert complex water The calorific value measurement of carrier heating is converted into a dual-meter differential-reading hot water flow meter, which is small in size, high in accuracy, low in manufacturing cost, strong in transparency, reliable and stable, and does not require external power control to start and maintain the calorific value meter. Background technique [0002] At present, the central heating water network management in the cold area of ​​northern my country is developing rapidly, but the effective calorific value measurement technology that involves the national economic interests cannot keep up with ...

Problems solved by technology

[0002] At present, the central heating water network management in the cold area of ​​northern my country is developing rapidly, but the effective calorific value measurement technology that involves the national economic interests cannot keep up with the development. In line with the national conditions, in the transformation of existing facilities, the installation layout is complex and difficult, the measurement is not reasonable, there is a lack of reasonable and restrictive heat supply quality measurement standards, and it is difficult for the buyer to consciously control the heat used by the buyer. It is in line with the civilized norms of the economic interests of both suppliers and buyers. It is not easy to communicate with each other when comparing the transparent and exact values, which leads to undue contradictions. Reasonable heat supply commercialization charges are frustrated, which hinders the implementation of energy-saving measures, and the national economic interests suffer a great loss.
