FIELD: oil and gas industry. ^ SUBSTANCE: device has body in form of calibrated cylinder. From both sides lids are connected to body. Inside the body separating piston and ball for mixing sample are placed. Also provided is hydraulic resistance for slow inlet of sample. Slide valve is used for safe inletting, pressurization and depressurization of taken fluid, is connected to lid and consists of rod with channels and bushing with clamp. Clamp is held between nuts interconnected by threads, one of which is connected to rod by thread. Needle valve consists of locking pin and axle-bearing and is used to drain pressure from closed space above slide valve prior to disconnection of sample-taking container from bed-testing equipment. ^ EFFECT: simplified construction, higher reliability. ^ 3 dwg |
