For ensureing the stability in the infrared spectroscopy process of the test, provide a sulfur hexafluoride gas composition sampling analysis device, in the gaseous storage of the sulfur hexafluoride that will await measuring to inclosed casing. Through the control of inlet end control valve with the end control valve of giving vent to anger, make gas introduction to the casing in, it connects gaseous pressure in the control casing to proclaim oneself through manometer, pressure sensor and superpressure evacuation. The device convenient and fast, easy operation.
Description
Technical field
The utility model relates to sampling equipment field, especially a kind of sulfur hexafluoride gas component sampling analysis device.
Background technology
Sulfur hexafluoride gas is as excellent insulation and arc-extinguishing medium, and be widely used in all kinds of high pressure, extra-high voltage electrical equipment, sulfur hexafluoride electrical equipment has become the major equipment in electrical network.Sulfur hexafluoride gas quality supervision is mainly to the control of its component concentration.The wavelength characteristic that infra-red sepectrometry can have according to different material is analyzed, therefore sulfur hexafluoride gas can be detected by infrared method, carry out qualitative and quantitative analysis according to spectrogram result other components to sulfur hexafluoride gas, judge that whether gaseous mass is qualified.
Sulfur hexafluoride is stored in steel cylinder usually in liquid form, gas is needed to pass in sampling analysis device when detecting, because gas can make pressure excessive when liquid state becomes gas, even if control by reduction valve the stability that output gas pressure can not ensure gas in measuring process completely, cause experimental repeatability excessively poor.Traditional sampling analysis device generally adopts the mode of single-pass gas port, will rely on vacuum pump evacuation in sampling process, and the residual gas in sampling jar is discharged.In actual use, for the sampler of single-pass gas port, only rely on vacuum pump to bleed, the foreign gas remained many times can not be made to extract out completely, thus bring interference easily to analysis sample.
Summary of the invention
The utility model can make pressure excessive in order to solve above-mentioned gas when liquid state becomes gas, even if control by reduction valve the stability that output gas pressure can not ensure gas in measuring process completely, cause the problem that experimental repeatability is excessively poor, propose a kind of sulfur hexafluoride gas component sampling analysis device, this device is convenient and swift, simple to operate.
A kind of sulfur hexafluoride gas component sampling analysis device, there is the housing for collecting gas, be arranged on both sides above housing and the admission line be connected with housing and outlet pipe, admission line is provided with pressure transducer, the inlet end operation valve that can show enclosure interior pressure successively along gas flow direction, outlet pipe is provided with outlet side operation valve, the emptying self-sealing joint of superpressure and tensimeter successively along gas flow direction.Outlet pipe is also connected with the vacuum extractor for vacuumizing to housing.
Principle of the present utility model is:
For guaranteeing the stability in infra-red sepectrometry process of the test, sulfur hexafluoride gas to be measured is stored in airtight housing.By the control of inlet end operation valve and outlet side operation valve, gas is made to be directed in housing; The pressure of gas in housing is controlled by the emptying self-sealing joint of tensimeter, pressure transducer and superpressure.
The beneficial effects of the utility model are:
This gas sampling device has two blow vents on collecting means, gas circuit is easy to connect, simple to operate, in the process of bleeding, be conducive to the residual gas of collecting means inside all to be extracted out, eliminate the interference of impurity, tightness is good, practical, safe and reliable, ensure that the accuracy of sample analysis process.This gas sampling device is by arranging for detecting the pressure transducer in housing, be easy to during sampling distinguish whether the gas in housing reaches balance with the gas of equipment under test inside, and be easy to when testing observe in housing and whether also have gas sample to remain, to prevent gas sample to be dispersed in air, cause air pollution.
