Description
Technical field
The present invention relates to a kind of pipe gas pressure stabilizing regulation system, refer to laboratory usefulness especially, have the highi degree of accuracy pipeline gas pressure stable regulation system of real-time monitoring and control.
Background technique
At present; Be used for the stable regulating system of pipeline pressure, as Chinese patent number be 95223675.3 disclosed, mainly be pressure control to fluid pipeline; Method through increasing the loop is regulated water output and pressure, and the application target of this scheme and applicable object are liquid.And pipeline gas pressure is regulated, and particularly the correlation technique for pressure stability in short-term and regulating system also is not reported.
In view of above situation, the present invention is directed in the market the blank of pipe gas pressure stabilizing system and study.
Summary of the invention
The purpose of this invention is to provide a kind of pipe gas pressure stabilizing regulation system, this system is a kind of meticulous regulating system that is used for stablizing the gas pipeline air pressure.
Above-mentioned purpose of the present invention realizes through following technological scheme:
A kind of pipe gas pressure stabilizing regulation system, this system comprises pressure monitor system and pressure regulating system two-part;
Said pressure regulating system comprises: fuel pot, and first reduction valve and the magnetic switch that connect successively, said magnetic switch is connected with the first knock out drum group; The said first knock out drum group the other end is connected with the modulating valve group through the second knock out drum group on the one hand, is connected with burner then; Then be connected with igniter with safe guidance flame respectively on the other hand through general decompressor;
Said pressure monitor system comprises gas pressure sensor, and this gas pressure sensor is located at the first knock out drum group and the top of the second knock out drum group in the said pressure regulating system.
A kind of optimal technical scheme is characterized in that: the said second knock out drum group is connected with the postcombustion jar with second reduction valve through magnetic switch.
According to nominal operating pressure and pipe fitter's delivered pressure of gas cylinder, it is identical with pipe fitter's delivered pressure to set blowing mouth pressure through first reduction valve.
Adopt the design of many knock out drums group, gas arrives the first knock out drum group through first reduction valve, and pipeline gas is carried out the voltage stabilizing first time; As required, the corresponding second knock out drum group of design was carried out the adjusting of voltage stabilizing once more before pipeline gas got into burner, kept the duration of work constant pressure.
Electromagnetic switch valve is all installed in each surge flask air outlet in the said first buffering gas tank group, and the actual pressure (air pressure tabular value) according to pipeline gas during burning is controlled each electromagnetic switch valve, and real-time regulated gets into the gas pressure of pipeline.
The said second knock out drum group is provided with the postcombustion jar through the electromagnetic switch valve and second reduction valve, when the pipeline gas drops is too fast, opens electromagnetic switch valve through second reduction valve, and gas make-up fast is provided, and guarantees that pipeline pressure is stable.
Gas in the said postcombustion jar is transported to the second knock out drum group through second reduction valve, converges with the main pipe combustion gas, gets into fuel device through the modulating valve group.
Said gas pressure sensor is monitored ducted gas pressure in real time.
Described pipe gas pressure stabilizing regulation system is regulated buffer gas conveyance conduit flow mainly according to the output signal of pipeline gas pressure transducer.
In combustion experiment, the heat flow that burning is produced is stable to be the key that system realizes, for guaranteeing the precision and the repeatability of burning, needs the gas pressure in the gas pipeline to keep constant.
The invention has the beneficial effects as follows: when carrying out combustion experiment, the variation in pressure that can guarantee combustion process intermediate conduit gas to produce stable burning, provides the ignition heat flow of standard less than 10%, realizes repeatably combustion experiment.
Through pipeline configuration design, monitor the constant of gas pressure in both realization combining pipelines in real time.Be applied to especially in quick, the accurate combustion system, when gas in the pipeline changed at short notice fast, system can reduce the fluctuation of gas pressure, was used to keep the stable of pipeline gas pressure.
Below in conjunction with accompanying drawing and embodiment the present invention is described further, but this and do not mean that restriction to protection scope of the present invention.
