Abstract

The utility model relates to a sampling apparatus at the well in oil field, in particular to a sampling apparatus that is against theft, freezing prevention and pollution prevention, which consists of an interference ring, an eccentric bolt lock against theft, a pin against theft, a pressure cap, a glan, a sealing rope, a continuous motion stem, a shell body, a rotating ring, a washer ring, a sealing stem, a drain pipe and a positioning pin; one side of the rotating ring is provided with the eccentric bolt lock against theft, the positioning hole is arranged at the lower end of continuous motion stem, and the pin against theft is inserted inside the positioning hole, the sealing stem is arranged at the top of shell body, then the sealing stem is connected with the upper part of continuous motion stem; the sampling apparatus has the advantages of being against theft, freezing prevention and pollution prevention, no residual oil left on the sampling spot, which not only reflect the composition of oil, but also remove the pollution brought by residual oil discharging.

Description

Antitheft, antifreeze, anti-pollution oil sealed sampling device

Technical field

The utility model relates to a kind of device that a kind of oilfield draws oil sample, especially can antitheft, antifreeze, the anti-pollution device that draws oil sample.

Background technology

At present, known oil field shaft mouth oil sealed sampling device is to use common valve, exists crude oil stolen, freezes winter to block up with dead oil easily to pollute problems such as oil wells in field.

Summary of the invention

In order to overcome the problem that the special-purpose oil sealed sampling device of existing oilfield exists, the utility model provides a kind of antitheft, antifreeze, anti-pollution oil sealed sampling device, this oil sealed sampling device, the seal bar some on housing top does not produce dead oil in the fluid of pipe network, can prevent from winter to freeze stifled, open antitheft eccentric bolt lock, insert anti-stealing and selling, hand is twisted rotating ring, and seal bar is opened, liquid flows out, prevent stolen, do not discharge dead oil during sampling, prevent to pollute.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of antitheft, antifreeze, anti-pollution oil sealed sampling device, by interference ring, antitheft eccentric bolt lock, anti-ly steal and sell, pressure cap, Glan, sealing cord, trace, housing, rotating ring, packing ring, seal bar, drain pipe and locating pin form, its special character is: a side of rotating ring has antitheft eccentric lock, there is locating hole the trace lower end, anti-stealing and selling is inserted in the locating hole, there is seal bar on the housing top, and seal bar is connected with the trace upper end.

The beneficial effects of the utility model are: can be antitheft, antifreeze stifled, and anti-pollution oil wells in field does not retain dead oil after drawing oil sample, can correctly reflect the oil sample composition, can remove the pollution of discharging dead oil and bringing again.
