Description

Samplers consisting of a casing, a sub-spring valve, a mixing device and a power lever mechanism are known.

A special feature of the described sampler is that it uses a block-wire lock to simultaneously close the valves. This greatly simplifies the design of the sampler, as it allows one to dispense with some parts susceptible to corrosion.

The drawing shows schematically the diagram of the sampler. The device consists of a housing 1, levers 2, a power mechanism with a copper needle 3, a shtoke 4 with a groove, a block 5, a cable 6, an upper valve 7, a receiving chamber 8 with a pinion bar 9, a lower valve 10 and a rod // for attaching the rope 6 to bottom valve} 0. Slot openings 12 are provided in the housing for the passage of a stream of fluid.

Before the sampler is lowered into the well, the valves are opened by simultaneously pressing the rods of the upper clanan 7 and the lower valve 10. The valves in the open position hold the lever 2 lever. The sampler is lowered into the well with open clans. Upon reaching the required depth of his go. In this case, the lever 2 with a copper needle 3 rests on the junction of the pipes, rotates around an axis, and relieves the stop from the stem 4 of the upper valve 7. The upper and lower valves, which are connected to each other with a block-wire lock, are closed simultaneously.

Subject invention

The sampler, consisting of a body, spring-loaded valves, a mixing device and a power lever mechanism, is characterized in that, in order to simplify the construction, it uses a block-and-wire lock to simultaneously close the valves.
