Abstract
The utility model relates to an insulating oil sampling valve, which comprises a valve body, an oil-filled electrical equipment communication port and a lab oil chemical analysis sampling port, wherein a chromatography online sampling communication port and a chromatography online sampling choke valve are arranged on the side wall of the valve body; a sample feeding port and a sample discharge port of the chromatography online sampling choke valve are arranged on a same end; a sampling valve oil channel and a branch oil way perpendicular to the sampling valve oil channel are connected with the sample feeding port of the chromatography online sampling choke valve; the sample discharge port is connected with the chromatography online sampling communication port through a bypass oil channel; and a valve rod of the chromatography online sampling choke valve is connected with the valve body in a threaded way. An O-shaped sealing ring is arranged on the valve rod; a sealing gasket is arranged at the front end of the valve rod; a screw cutter edge for regulating the valve rod is arranged on the cross section of the rear end of the valve rod; and a sealing cap is also arranged at the end part of the valve body. The valve is good in sealing property and simple in installation; the oil leakage is prevented effectively and the oil ways are safe and are not affected mutually, so that too much oil leakage which may make the equipment dirty during the sampling process is prevented; and furthermore the lab oil chemical analysis sampling is realized, and the insulating oil online monitoring system sampling is realized as well.
Description
Technical field
The utility model relates to a kind of insulating oil sampling valve.
Background technique
At present, electric power system is regularly drawn oil sample when carrying out chromatographic analysis to oil-filled equipments such as transformer, mutual inductor, switch sleeve pipes, because the riding position of oil-filled equipments such as transformer, mutual inductor is higher; Must climb to the higher position with ladder when taking a sample and carry out very inconvenience of HAS; Simultaneously, because the valve seal poor-performing of fuel outlet valve, oil impregnate is serious; Become stream oil too much in sampling process, make the serious and contaminated equipment of insulating oil loss.
Development along with the POWER SYSTEM STATE detection technique; Oil-filled insulation of electrical installation oil on-line detecting system has obtained common application; This type systematic need be from the sample tap real time sample of sampling cock in the proper functioning chamber, and the sampling cock of originally single sample tap can not satisfy the requirement of this multifunction sampling, and a lot of single sampling cock through transforming; Mostly be through increasing the parts of threeway and so on; On-line monitoring system is got oil automatically and the lab analysis manual work is drawn oil sample though can satisfy simultaneously, has increased a lot of piping nodes, and the phenomenon of leakage of oil happens occasionally.Particularly substation transformer equipment is installed, and does not allow oil and runs leakage, can increase electric leakage like external stop valve, and in addition when mounted, some oil that is bound to runs and leaks, and does not meet electric substation's requirement, thus the never solution of this difficult problem, so hidden danger increases greatly.
The model utility content
The technical problem that the utility model will solve is: overcomes the deficiency in the existing technology, a kind of good seal performance is provided, install simply, not only effectively avoided leakage of oil, and oil circuit safety and being independent of each other.
The utility model solves the technological scheme that its technical problem adopted: a kind of insulating oil sampling valve; Have valve body, oil-filled electrical equipment connection mouth and laboratory oiling credit and analyse sample tap; The sidewall of valve body is provided with online sampling connection mouth of chromatogram and the online sampling stop valve of chromatogram; Chromatogram online sampling stop valve injection port and outlet are located at same end; The perpendicular branch's oil circuit of sampling cock oil duct connects the injection port of the online sampling stop valve of chromatogram, and outlet connects the online sampling connection mouth of chromatogram through the bypass oil duct, and the valve rod of the online sampling stop valve of chromatogram 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, and terminal section is provided with the screw edge of a knife of regulating valve stem, and valve end also is provided with sealed cap.
Further, the online sampling connection mouth of the described chromatogram of the utility model is located at two different positions respectively with the online sampling stop valve of chromatogram, the two on the horizontal plane of same substantially horizontal, 90 ° at interval.
The beneficial effect of the utility model is: good seal performance; Install simply, not only effectively avoided leakage of oil, and oil circuit safety and being independent of each other; Avoid in sampling process, causing stream oil too much; Contaminated equipment also can satisfy the laboratory oiling credit appearance of extracting, and also can satisfy the sampling of insulating oil on-line monitoring system.
