Abstract

The invention discloses a bottom sampling barrel. The bottle sampling barrel comprises a hoisting ring, a shell assembly and a valve element assembly, wherein the shell assembly is a hollow shell with a vertical central axis and comprises an upper end sleeve, a shell and a lower end sleeve which are fixedly connected with one another vertically; the valve element assembly is arranged in a cavity of the shell assembly and comprises an upper valve element, a connecting rod and a lower valve element; the central axis of the connecting rod is vertical; the upper valve element and the lower valve element are respectively connected to the upper end and the lower end of the connecting rod fixedly; the lower end of each of the upper valve element and the lower valve element is a cone with the small bottom end; in a natural state, the upper valve element and the lower valve element respectively drop into taper holes of the upper end sleeve and the lower end sleeve; the tip of the cone of the lower valve element extends out of the lower end surface of the lower end sleeve; ring slots are respectively formed in the outer wall of the cone of the upper valve element and the outer wall of the cone of the lower valve element; O-shaped sealing rings are respectively arranged in the ring slots; in the natural state, the O-shaped sealing rings on the upper valve element and the lower valve element are respectively in close contact with the surfaces of the taper holes of the upper end sleeve and the lower end sleeve. The bottle sampling barrel is further characterized in that a counter weight is arranged on the connecting rod. The bottom sampling barrel can be used for liquid bottom sampling.

Description

technical field [0001] The invention relates to a sampling device, in particular to a liquid sampling bucket. Background technique [0002] The sampler used in the current industrial field is to realize the sampling of the liquid in the container in a simple way, but it cannot realize the sampling of the liquid in the designated part of the container, such as sampling the bottom, the sampling liquid is not representative and random. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes a bottom sampling barrel which can be used for liquid bottom sampling. [0004] The present invention achieves technical goals through the following technical solutions. [0005] The improvement of the bottom sampling barrel is that it includes a suspension ring, a shell assembly, and a valve core assembly; the shell assembly is a hollow shell with a vertical central axis, including an upper end sleeve, a housing, and a lower end slee...
