Filtering type gas turbine flowmeter with gas leakage alarm function

Abstract

The invention discloses a filtering type gas turbine flowmeter with a gas leakage alarm function, and relates to the technical field of filtering type gas turbine flowmeters. The filtering type gas turbine flowmeter comprises a flowmeter body, wherein the flowmeter body comprises a connecting pipeline, a mounting frame, a display device and an alarm, the mounting frame is vertically connected to the middle side of the top of the connecting pipeline, the top of the mounting frame is connected with the display device, the two ends of the connecting pipeline are connected with first connecting discs, the two first connecting discs are connected with a gas pipe structure, and one end of the gas pipe structure is provided with a second connecting disc detachably connected with the first connecting discs. When the filtering type gas turbine flowmeter and the gas pipe structure are installed and used, the sealing performance of the connecting position is higher, the connecting position can be monitored in real time at the same time, when gas leakage occurs, alarm reminding can be conducted in time, the gas loss rate during gas leakage is reduced, the use is more flexible and convenient, and the filtering type gas turbine flowmeter is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of filter-type gas turbine flowmeters, in particular to a filter-type gas turbine flowmeter with an air leakage alarm function. Background technique [0002] The gas turbine flowmeter is mainly used for flow measurement of air, nitrogen, oxygen, hydrogen, biogas, natural gas, steam and other media fluids in industrial pipelines. It is almost independent of fluid density, pressure, temperature, viscosity and other parameters when measuring volume flow in working conditions. Impact. No moving mechanical parts, so high reliability and low maintenance. Instrument parameters can be stable for a long time. The gas vortex flowmeter adopts piezoelectric stress sensor, which has high reliability and can work in the working temperature range of -20℃~+250℃. It has analog standard signal and digital pulse signal output. It is easy to be used with computer and other digital systems. It is a relatively advanced and ide...

Problems solved by technology

[0003] At present, when the filtered gas turbine flowmeter is connected with the gas pipe structure, most of the filtered gas turbine flowmeters only have the function of monitoring the flow of the filtered gas, and the current filter gas turbine flowmeter and the gas pipe The structural connection is only connected by bolts, and the sealing is not strong, and when there is an air leak during the connection, it cannot be monitored in time, resulting in a high gas loss. For this reason, we designed a A filter type gas turbine flowmeter with gas leakage alarm function is developed to solve the above problems
