For the problems referred to above, a kind of flow measurement pipeline section that the present invention is provided reaches goal of the invention by following technical essential：A kind of flow measurement pipeline section, including the flow measurement cell being series on pipeline, the flow measurement cell includes two groups of flow measurement paths, and two groups of flow measurement path in parallel, pipe fitting on flow measurement path includes effusion meter and two manual block valves, and the effusion meter is series between manual block valve.
Specifically, effusion meter has higher repair rate compared to other pipe fittings or pipeline section in use, for adapting to the uninterrupted operation of pipeline in prior art, bypass line is set at the two ends of effusion meter usually, and the metering of fluid cannot be realized when bypass line runs.In the present invention, using the structure setting of two groups of flow measurement paths in parallel on pipeline, the switchover operation of wall scroll flow measurement path is facilitated implementation, so as to realize the uninterrupted metering of pipeline, beneficial to the measuring accuracy of pipeline flow.In the present invention, by cutting off two manual block valves on wall scroll flow measurement path, you can realize the effusion meter maintenance on the flow measurement path or safeguard.It is preferred that above-mentioned manual block valve is with the gate valve for well blocking ability.
Further technical scheme is：
For the benefit of end of line flows out the quality of medium, improves flow meters work environment etc., is additionally provided with filter on the flow measurement path, and the filter is located at effusion meter front end, and the filter is located between two manual block valves.The position of filter arranges the maintenance or maintenance for being easy to filter.
For ease of the adjustment of the flow of pipeline, electric control valve on the flow measurement path, is additionally provided with, the electric control valve is located between two manual block valves.The position of electric control valve is arranged to be easy to overhaul electric control valve and safeguarded.
For realizing pipeline flow volume adjust automatically, the flow is calculated as differential pressure electronic flowmeter, and the control module of the electric control valve is connected with the outfan of effusion meter.
For ease of the monitoring of pipeline other specification, thermometer on the flow measurement path, is additionally provided with, the thermometer is located between two manual block valves.The position of thermometer is arranged to be easy to overhaul thermometer and adjusted.
The invention has the advantages that：
Present configuration is simple, using the structure setting of two groups of flow measurement paths in parallel on pipeline, facilitates implementation the switchover operation of wall scroll flow measurement path, so as to realize the uninterrupted metering of pipeline, beneficial to the measuring accuracy of pipeline flow.In the present invention, by cutting off two manual block valves on wall scroll flow measurement path, you can realize the effusion meter maintenance on the flow measurement path or safeguard.
