During sampling, the sampling bottleneck is put in the mouth lower end of will taking a sample, and sampling bottle is screwed on the porose bottle cap in the bottle cap stationary pipes of dsah-pot base plate bottom, lets go, and opens the sampling gate and carries out sampling operation, closes the sampling gate after sampling finishes, and backs out sampling bottle, gets final product.
When the too much or porose bottle cap of greasy dirt in the sampler damages, can back out the dsah-pot base plate, clean or change porose bottle cap.
The beneficial effect of the utility model is: after adopting the utility model, and splash phenomenon in the time of preventing the oil well sampling effectively, security performance is reliable; Easy and simple to handle, simple in structure, be convenient to clean; Can change bottle cap at any time, to adapt to dissimilar sampling bottles, also available other oil resistant nonmetals processing and fabricating; Very strong applicability is arranged, and is the new design of a novelty, progress, practicality.
The utility model proves through experiment: after utilizing this utility model, can prevent the splash phenomenon when oil well is taken a sample effectively, guarantee sampling operation personnel's safety, greatly reduce working strength of workers, be fit to the indoor and outdoor sampling of all oil wells.
Practical implementation case below in conjunction with accompanying drawing is done further explain to the utility model.
