Description

Technical Field

[0001] The utility model relates to the technical field of orifice flowmeters, in particular to an antifreeze integrated orifice flowmeter. Background Art

[0002] The antifreeze integrated orifice flowmeter is a high range ratio differential pressure flow device that combines a standard orifice plate with a multi-parameter differential pressure transmitter (or differential pressure transmitter, temperature transmitter and pressure transmitter). It can measure the flow of gas, steam, liquid and lead, and is widely used in process control and measurement in the fields of petroleum, chemical industry, metallurgy, electricity, heating, water supply, etc. The throttling device is also called a differential pressure flowmeter, which is composed of a primary detection device (throttling device) and a secondary device (differential pressure transmitter and flow display instrument) and is widely used in gas, steam and liquid flow measurement. It has a simple structure, easy maintenance and stable performance.

[0003] When measuring flow with traditional steam media, a condenser needs to be installed. In winter, the water in the three-valve group and the connecting pipe connected to the condenser will freeze. In severe cases, the differential pressure transmitter may be damaged by freezing, and anti-freeze measures such as heating need to be added. Utility Model Content

[0004] The purpose of the utility model is to provide an antifreeze integrated orifice flowmeter. The steam is condensed into water through the radiator and flows back into the pipeline, so that the flow rate of the steam medium can be measured without adding traditional antifreeze measures such as heating. The utility model also integrates the differential pressure transmitter, the three-valve group and the orifice flowmeter into one, which effectively reduces the length of the pressure taking pipe and reduces the material cost.

[0005] To achieve the above-mentioned purpose, an antifreeze integrated orifice flowmeter is provided, comprising: a flange, an integrated component and a radiator, the top of the integrated component is fixedly connected to a first radiator, the top of the first radiator is fixedly connected to a second radiator, the top of the second radiator is fixedly connected to a two-valve group, the top of the two-valve group is fixedly connected to a three-valve group, and the top of the three-valve group is fixedly connected to a differential pressure transmitter.

[0006] According to the antifreeze integrated orifice flowmeter, flanges are provided at both ends of the integrated component, and fasteners are bolted between the flanges.

[0007] According to the antifreeze integrated orifice flowmeter, the second radiator is an annular structure.

[0008] According to the antifreeze integrated orifice flowmeter, the number of the fasteners is determined according to the pressure resistance grade.

[0009] The above scheme has the following beneficial effects:

[0010] The utility model is provided with a first radiator, a second radiator, two valve groups and a differential pressure transmitter. The steam antifreeze integrated orifice flowmeter integrates the orifice plate, the radiator, the two-valve group, the three-valve group and the differential pressure transmitter. The steam is condensed into water through the radiator and flows back into the pipeline, so that the flow rate of the steam medium can be measured without adding traditional antifreeze measures such as heating. The utility model also integrates the differential pressure transmitter, the three-valve group and the orifice flowmeter, which effectively reduces the length of the pressure taking pipe and reduces the material cost. At the same time, the differential pressure transmitter and the orifice flowmeter are integrated, which effectively reduces the installation workload on site and avoids measurement errors caused by improper installation.
