Abstract
The utility model relates to pressure conduit pulse noise immune damper, comprising a cylinder (2), inside the cylinder is arranged with a damper plate (4), and both ends of the cylinder (2) are connected with pipe coupling (1) respectively. The utility model is designed according to the principle that the pulse index of liquid fades with the ratio of distance and through-flow area. The damper of the utility model is positioned on the pressure conduit between the pipeline to be tested and the pressure detecting equipment, both ends of the damper are respectively communicated with the pressure conduit and the pressure detecting equipment through the pipe coupling. The pulse medium in the pipeline to be tested enters into the damper through the pressure conduit. Through damping action of damping sheet, the pulse medium effectively slows the pressure pulse of the tested medium as well as effectively lowers down the pulse amplitude of the pulse pressure or filters pulse, improves the sampling precision of pressure of gas in the sampling conduit and stability, and causes the detection result of the pressure inspection equipment more accurate and stable.
Description
Technical field

Background technology
In process of production, need the pressure of the gas in the pipeline be detected.Detect as pressure media such as the coal gas in the pipeline, steam, oxygen, nitrogen, argon gas, air.Adopting pressure conduit mode that the gas in the pipeline is detected is the detection method of using always, and this method is to draw a pressure conduit on tested pipeline, and instrument such as setting pressure table on the pressure conduit is to record the pressure of pipeline internal medium.
Existing pressure catheter pressure detection method is that tensimeter equal pressure checkout equipment is directly installed on the pressure conduit, but some place in pipeline, locate as engine, compressor, fan blower, pressurization delivery side of pump etc., the pressure in medium pipeline and the pressure conduit is a pulsating quantity.During detection, pressure is the wave curve and shakes, and the collection of data in the fluctuation disturbed sampling conduit of pressure (primary instrument can't steady display) makes the precision that detects reduce, and brings obstacle for the adjusting and the control of process pipe.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of pressure conduit pulsation anti-interference damper is provided, this damper can be arranged on the pressure conduit between tested pipeline and the pressure checking device, can effectively reduce the pulsation amplitude or the filtering pulsation of fluctuation pressure, make that the testing result of pressure checking device is more accurate and stable.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
Pressure conduit pulsation anti-interference damper, it comprises cylindrical shell, is provided with damping sheet in the cylindrical shell, the cylindrical shell two ends are respectively equipped with pipe adapter.
In the such scheme, be provided with the damping sheet more than two or two in the cylindrical shell.
In the such scheme, be provided with the tubular pad between the adjacent damping sheet.
In the such scheme, pipe adapter is articulation, pipe adapter be connected with cylinder inboard wall by pipe thread.
In the such scheme, be provided with stage clip between pipe adapter and the damping sheet.
In the such scheme, be provided with tubular between stage clip and the damping sheet and regulate pad.
The principle of work of the utility model pressure conduit pulsation anti-interference damper: it designs according to the pulse index of the fluid ratio attenuation principle with distance and flow area.The utility model damper is arranged on the pressure conduit between tested pipeline and the pressure checking device, and the damper two ends are communicated with pressure conduit, pressure checking device by pipe adapter respectively.Pulsation medium in the tested pipeline enters damper by the pressure conduit, after the damping action of damping fin, the mild effectively pressure pulse of measured medium, effectively reduce the pulsation amplitude or the filtering pulsation of fluctuation pressure, improve the sampling precision and the stability of gaseous tension in the sampling catheter, make that the testing result of pressure checking device is more accurate and stable.
