8. the sampling method of the described petroleum liquid clear glass of claim 1 ST is characterized in that:
1) gets the method for point sample
(1) preliminary work: cock is screwed in base stop up the bottom sample intake passage, concordant with the threaded stem upper edge with revolving about 1cm on the positioning screw cap, purpose is to be the descending headspace of valve block; Get into the hook hole slot of valve pocket with hook extruding push rod; Portable chi tep reel is held Zuo Dinghuan and right rotating ring simultaneously, and at this moment because of the gravity of the ST elastic force much larger than spring, hook remains in the hole slot; The Nei Ding plane of mouth valve gap is under action of gravity; Drop on the last plane of valve block, no gap after fitting in two planes, the intake and exhaust liquid hole of airtight mouthful of valve gap
,Get into point sample and treat the sample introduction state;
(2) test procedure: carry petroleum liquid clear glass ST, loosen right rotating ring and emit the chi band, make ST drop to the oil product liquid level, stop right rotating ring time-out and emit the chi band; The position that the scale of observing right rotating ring points to ring decided at the higher level but not officially announced is the zero point of sampling depth, loosens right rotating ring and whenever turns around and be 0.5m, deep bid 1 m/ circle; Emitting the corresponding number of turns according to required sampling depth, is 5 m like sampling depth, then need put 10 circles; After arriving required sampling depth, stop right rotating ring and stop to emit the chi band, carrying about 20cm about 20cm of decline rapidly again on the chi tep reel; This, chi band hook lost the pulling force to push rod moment, and the elastic force of spring promotes to hook handle when push rod will link up with the ejection hole slot, and valve block slides downwards because of action of gravity; Open the intake and exhaust liquid hole of mouthful valve gap, get into point sample sample introduction state, after waiting for the several seconds; After transparent glass container advances full fluid sample in the ST, right rotating ring is inverted to proposition petroleum liquid clear glass ST, is avoiding under the sunshine direct projection condition; The presentation quality of sample is judged in visual inspection, gets check analysis that strict lucifuge requires when using sample, can be on the outer wall cover of transparent glass container the lucifuge pipe;
2) get the method for bottom appearance
(1) preliminary work: cock is screwed out base; Valve rod stops up the bottom sample intake passage under the effect of gravity, little tight with being threaded under the positioning screw cap, the Nei Ding plane of mouthful valve gap is pasted with the last plane of valve block mutually close sample intake passage; To link up with handle and be connected, promptly get into original pattern state to be advanced;
(2) test procedure: make petroleum liquid clear glass ST drop to the oil vessel bottom; Valve rod upwards slides owing to received the reacting force of oil vessel bottom surface; Thereby the fluid sample passage of base and the gas passage on the valve pocket are opened, got into original pattern sample introduction state;
ST proposes ST after advancing full sample, and the presentation quality of sample is judged in visual inspection; When taken a sample to check in many cabins; An available clear glass ST is got the sample in a full cabin; As the reference sample of the colourity of this batch oil product presentation quality, clarity etc., with another clear glass ST to other each cabin or point is taken a sample and the contrast of reference sample is judged;
3) decision rule: product oil is sold examination, and the quality of same breed, batch oil product should be evenly qualified, and presentation qualities such as the colourity of oil tank, each cabin oil product of oil truck ship, clarity, water are assorted, viscosity, smell should identical unanimity or in normal range; Presentation quality inspection purpose is to find the inconsistent or abnormal oil product of presentation quality, is convenient to emphasis check analysis or evaluation, avoids partial confounding, pollution, rotten oil product, and influence is managed and application safety;
4) report: find with batch oil product through comparison; Have that sample colourity in car, ship, the cabin, clarity, water are assorted, viscosity, smell presentation quality be inequality; Or it is unusual; Possibly cause oil quality not meet standard, should report when influence is safe in utilization, sampling in case of necessity send quality inspection organization to carry out further check analysis or evaluation.
