Abstract

The invention discloses sample bucket bottom one, including suspension ring, housing unit, core assembly；The hollow housing that centered by housing unit, axis is vertically arranged, including fixing the upper end set of connection, housing, lower end set up and down；Core assembly is arranged in housing unit inner chamber, and including upper valve core, connecting rod, bottom spool, connecting rod central axis is vertically arranged, and upper valve core, bottom spool are respectively fixedly connected with the upper and lower side in connecting rod；Upper valve core, bottom spool lower end be small end under cone, under naturalness, upper valve core, bottom spool respectively fall in upper end set, lower end set taper hole in, set lower surface, lower end is stretched out at the cone tip of bottom spool；Upper valve core, the cone outer wall of bottom spool are respectively equipped with annular groove, are respectively equipped with O-ring seals in annular groove；Under naturalness, the taper hole intimate surface contact that the O-ring seals on upper valve core, bottom spool overlaps with upper end set, lower end respectively, further improvement is that: connecting rod is provided with balancing weight.The present invention can be used for liquid bottom sampling.

Description

Bottom sample bucket

Technical field

The present invention relates to a kind of sampler, be specifically related to a kind of liquid sampling bucket.

Background technology

The sampler that current industrial field uses is to realize the sampling to vessel liquid plain mode, but can not realize appearance The liquid of device appointed part is sampled, and such as the sampling to bottom, sampling liquid does not has representativeness, random big.

Summary of the invention

The present invention is directed to the deficiencies in the prior art, propose a kind of bottom sample bucket that can be used for liquid bottom sampling.

The present invention is achieved through the following technical solutions technical goal.

Bottom sample bucket, it thes improvement is that: include suspension ring, housing unit, core assembly；During described housing unit is The hollow housing that mandrel line is vertically arranged, including fixing the upper end set of connection, housing, lower end set up and down；Described suspension ring and upper end set hinge Connect；Described core assembly is arranged in housing unit inner chamber, including upper valve core, connecting rod, bottom spool, connecting rod central axis Being vertically arranged, upper valve core, bottom spool are respectively fixedly connected with the upper and lower side in connecting rod；Described upper valve core, bottom spool lower end are small end Cone under, under naturalness, upper valve core, bottom spool respectively fall in the taper hole of upper end set, lower end set, the cone of bottom spool Set lower surface, lower end is stretched out at tip；Described upper valve core, the cone outer wall of bottom spool are respectively equipped with annular groove, are respectively equipped with O in annular groove Shape sealing ring；Under naturalness, the O-ring seals on upper valve core, bottom spool is tight with the taper hole surface of upper end set, lower end set respectively Contiguity is touched, and forms upper and lower sealing structure, becomes to close inner chamber by housing unit bore seal.

In said structure, described connecting rod is provided with balancing weight.

When liquid bottom samples, the present invention puts into liquid bottom to be sampled, and valve core cone is most advanced and sophisticated and to be sampled instantly During liquid bottom contacts baseplate, core assembly moves up relative to housing unit, can open upper-lower seal structure of the present invention, sample Liquid can flow in housing unit inner chamber, discharges the air in housing unit inner chamber simultaneously；At the end of sampling, the present invention upwards moves Dynamic, under core assembly Gravitative Loads, upper-lower seal structure of the present invention is airtight, liquid closed in housing unit by sampled In chamber.

The present invention compared with prior art, has the positive effect that:

1, by the taper integrated structure of upper and lower side, it is possible to achieve liquid bottom samples.

2, connecting rod is provided with balancing weight, can increase the weight on core assembly, thus increase the close of upper-lower seal structure Envelope effect.

Accompanying drawing explanation

Fig. 1 is present configuration schematic diagram.

Fig. 2 is I enlarged schematic partial view in Fig. 1.

Fig. 3 is II enlarged schematic partial view in Fig. 1.

Detailed description of the invention

Below according to accompanying drawing and the invention will be further described in conjunction with the embodiments.

Bottom shown in the drawings sample bucket, including suspension ring 1, housing unit 5, core assembly 4；Axle centered by housing unit 5 The hollow housing that line is vertically arranged, including fixing the upper end set 5.1 of connection, housing 5.2, lower end set 5.3 up and down；Suspension ring 1 overlap with upper end 5.1 be hinged；Core assembly 4 is arranged in housing unit 5 inner chamber, including upper valve core 4.1, connecting rod 4.2, bottom spool 4.3, joins Pouring weight 4.4, connecting rod 4.2 central axis is vertically arranged, and it is upper that upper valve core 4.1, bottom spool 4.3 are respectively fixedly connected with in connecting rod 4.2 Lower end, balancing weight 4.4 is sleeved in connecting rod 4.2；Upper valve core 4.1, bottom spool 4.3 lower end be small end under cone, from So under state, upper valve core 4.1, bottom spool 4.3 respectively fall in the taper hole of upper end set 5.1, lower end set 5.3, the cone of bottom spool 4.3 Body tip is stretched out lower end and is overlapped 5.3 lower surfaces；Upper valve core 4.1, the cone outer wall of bottom spool 4.3 are respectively equipped with annular groove, divide in annular groove It is not provided with O-ring seals；Under naturalness, the O-ring seals on upper valve core 4.1, bottom spool 4.3 respectively with upper end set 5.1, under The taper hole intimate surface contact of end set 5.3, forms upper and lower sealing structure, becomes to close inner chamber by housing unit 5 bore seal.
