Abstract
The invention relates to an insertion-type electric rotation flow meter for closed pipeline conductive liquid flow measurement widely used in the oil, chemical industry, etc. comprises: the accumulation calculate instrument 1, the top pressure cap 2, the top pressure lid 3, the sensor 4, the PTFE protective cover 5, 6, the probe 7, the PTFE outside cover 8, the swirl generator 9, the magnet steel 10, the bottom prepared cap 11, the bottom pressure lid 12, the main-body 13, the sealed ring 14, 15, the supporting rack 16, the locking nut 17 and the connecting component 18, and the accumulation calculate instrument 1 connecting on the top of the top pressure cap 2, the supporting rack 16 installed in the main-body 13, the probe 7 equipped in the hole of the supporting rack 16, the PTFE protective cover 5, 6 and the PTFE outside cover 8 jacket installed outside the probe 7; and the swirl generator 9 is jointing at the lower side of the probe 7 with horizontal through-hole side in the main-body; the sensor 4 is installed in the top pressure lid 3 of the main-body, and the magnet steel 10 installed on the top of the bottom pressure lid 12; the bottom of the core main-body 13 inserts in the vertical middle hole of the connecting component 18, and integrates with the bolt. The flow meter uses core body insertion-type architecture, easy to processing, manufacture and installation and maintenance, and it can obtain good effect in the conductive liquid flow measurement.
Description
Technical field:
[0001] The invention relates to an instrument device for measuring the flow of conductive liquid in closed pipelines in various industries such as petroleum and chemical industry. Background technique:
[0002] In the process of production and operation in a wide range of industries such as petroleum and chemical industry, it is necessary to use conductive liquid flow meters to measure the flow of the working medium in the closed pipeline. At present, the structure of the conductive liquid flowmeter used in the field is relatively complicated, and the inner cavity is equipped with lining and rotating parts. Not only the production cost is high, the processing is difficult, but also it is prone to jamming during use and operation, which affects the liquid flow measurement and pipeline installation. normal production and operation. The electro-rotary flowmeter developed and used in recent years has no rotating parts in the inner cavity, which solves the probl...
