Problems solved by technology
In the prior art, valves and gas flowmeters are usually installed separately in the pipeline as two independent devices. The problems with such separate installations lie in the following two points: First, the installation position of the gas flowmeter needs to be long before and after. As a necessary condition for flow measurement, the pipeline occupies the installation position of the pipeline and wastes installation space; secondly, it increases installation time, reduces construction efficiency, and wastes manpower

The invention discloses a valve for monitoring gas flow in real time and a valve flow measuring method. A sleeve is mounted in a middle cavity of a valve body, and the two ends of the sleeve are supported by the valve body and a valve deck correspondingly. A through hole is formed in the center of the valve deck, a valve rod enters the middle cavity of the valve body through the through hole in the center of the valve deck, and the bottom of the valve rod is connected with a valve element in the center of the sleeve; and the valve element is driven by the valve rod to vertically move in the axial direction of the valve rod. An inlet pressure sensor and a temperature sensor are mounted on the side wall of a valve inlet pipeline, a rectifying device is mounted in the valve inlet pipeline, and an outlet pressure sensor is mounted on the side wall of a valve outlet pipeline. All the pressure sensors are connection with a flow data processing module for communication. According to the valvefor monitoring the gas flow in real time and the valve flow measuring method, a flow measuring function is integrated in the valve, the gas flow passing through the valve is detected in real time, and convenience and high efficiency are achieved; the structure is compact, the size is small, and the mounting space is saved; and the turbulent flow flowing in the valve, gas compressibility and temperature influences are considered in the measuring process, and the measuring precision is high.
Description
technical field [0001] The invention relates to the field of gas flow measurement and valves, in particular to a valve for real-time monitoring of gas flow. Background technique [0002] Valves and gas flow meters are essential equipment in gas pipelines. In the prior art, valves and gas flowmeters are usually installed separately in the pipeline as two independent devices. The problems with such separate installations lie in the following two points: First, the installation position of the gas flowmeter needs to be long before and after. As a necessary condition for flow measurement, the pipeline occupies the installation position of the pipeline and wastes installation space; secondly, it increases installation time, reduces construction efficiency, and wastes manpower. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a valve for real-time monitoring of gas flow, which has a compact structure and small volume...
