The single sampling valve can carry out two types of sampling which can be separately controlled, the sampling valve does not need to be connected with an external switching valve, the mounting is simplified, oil leakage is effectively prevented, and the oil passages are safe and do not affect one another during operation; and the sampling valve not only can be used for sampling for the chemical analysis of oil in a laboratory, but also can be used for the sampling of an on-line insulating oil monitoring system.
Description
Technical field
The utility model relates to a kind of oil-filled electrical equipment sample valve, is mainly used in the sampling of oil-filled insulation of electrical installation oil.
Background technology
The large-scale oil-filled electrical equipment of electric power, as transformer, reactor etc., inside is filled with transformer oil as insulating material, for detecting the Quality of Transformer Oil level, micro-water content etc. in, oil dissolved gas content withstand voltage, the oil as oil, judge the safe operation situation of transformer, national standard CB/T 7597-2007 " oil for electric power (transformer oil, steam turbine oil) sampling method " has stipulated the sampling method of oil-filled electric equipment.And no matter be the fuel outlet valve of oil-filled electrical equipment outfit or the sample valve of reequiping afterwards at present, generally have only one to be used for the chemico-analytic sample tap of laboratory oil.
Development along with the POWER SYSTEM STATE monitoring technology, oil-filled insulation of electrical installation oil on-line monitoring system has obtained widespread usage, this type systematic need be from the sample tap real time sample of sample valve when operate as normal, the sample valve of originally single sample tap can not satisfy the requirement of this multifunction sampling, and a lot of single sample valve through transforming, mostly be by increasing the parts of threeway and so on, on-line monitoring system is got oil automatically and lab analysis is manually drawn oil sample though can satisfy simultaneously, but a lot of piping nodes have been increased, the phenomenon of leakage of oil happens occasionally, this difficult problem never solves, so hidden danger increases greatly.
Summary of the invention
The purpose of this utility model is: design a kind of laboratory oiling credit sample of extracting that both can satisfy, also can satisfy the multi-sampling-port insulating oil sampling valve of insulating oil on-line monitoring system sampling, to solve the problem that prior art exists.
Realize that the technical scheme that the utility model purpose is adopted is: design a kind of sample valve with two sample taps, sample tap is used for the laboratory oiling credit sample of extracting, a sample tap is used for the sampling of insulating oil on-line monitoring system, its key is: the online sampling connector of chromatogram is located on the sample valve body wall, the online sampling connector of chromatogram is located at two different positions respectively with its stop valve, the online sampling stop valve of chromatogram also is located on the sample valve body wall, the two horizontal direction in one plane, 90 degree at interval; The sample introduction asphalt channel of the online sampling connector of chromatogram is that the sample valve oil duct enters the online sampling connector of chromatogram again after the online sampling connector of chromatogram stop valve valve body comes out.
At the online sampling connector of chromatogram stop valve one end two mouths are arranged, an injection port, an outlet, the sample valve oil duct is through the injection port of the online sampling connector of branch's oil circuit connection chromatogram stop valve, and outlet connects the online sampling connector of chromatogram through road binders road, one side; The valve rod of the online sampling connector of chromatogram stop valve is through being threaded on the valve body, valve rod is provided with the O V-shaped ring, and front end is provided with sealing gasket, is used for the injection port on the sealed valve body, distal end faces is provided with the screw edge of a knife that is used for regulating valve stem, and valve end is provided with sealing cap.
Good effect of the present utility model is: a valve member has been finished two kinds of samplings, and has the respectively separately function of control, does not need the outside connected switch valve, has simplified installation, has effectively avoided leakage of oil, oil circuit safety and being independent of each other during work; Both can satisfy the laboratory oiling credit sample of extracting, also can satisfy the sampling of insulating oil on-line monitoring system.
