Description
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 fixed point
Sampling.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of spot sampling bucket that can realize spot sampling.
The present invention is achieved through the following technical solutions technical goal.
Spot sampling bucket, it thes improvement is that: include housing unit, core assembly；Axle centered by described housing unit
The hollow housing that line is vertically arranged, including fixing the upper end set of connection, housing, lower end set up and down；Described core assembly include 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；Institute
State connecting rod to be arranged in housing unit inner chamber；Described upper valve core protrudes upward upper end and puts end face, and upper valve core stretches out upper end set
The part of upper surface is provided with the spacer pin of horizontal；Set bottom, described lower end be provided with big end under taper hole, upper end set is provided with big
Hold under taper hole；Small end it is equipped with in upper cone on described upper valve core, bottom spool；Described upper valve core, the cone of bottom spool
Outer wall is respectively equipped with annular groove, is respectively equipped with O-ring seals in annular groove；Described core assembly moves up relative to housing unit, on
Cone on spool, bottom spool respectively falls in the taper hole of upper end set, lower end set, and the O-ring seals on upper valve core, bottom spool divides
The taper hole intimate surface contact that other and upper end set, lower end are overlapped, forms upper and lower sealing structure, housing unit bore seal is become envelope
Close inner chamber.
In said structure, described connecting rod is provided with balancing weight.
In said structure, set taper hole bottom, described lower end outer wall is provided with several radial opening groove.
When liquid spot sampling, the present invention puts into the appointment position of liquid to be sampled, moves up and down rapidly, and back and forth 3
More than secondary, move up and down can produce a pump efficiency should, promote the sealing structure of bottom spool of the present invention quickly to open and close, liquid
Entering in housing unit inner chamber, after sampling terminates, core assembly moves up, upper-lower seal structure quick closedown of the present invention, will
Sampled is liquid closed in housing unit inner chamber.During without sampling, under core assembly Gravitative Loads, the present invention is the closeest
Seal structure is quickly opened.
The present invention compared with prior art, has the positive effect that:
1, liquid spot sampling can be realized.
2, connecting rod is provided with balancing weight, can increase upper-lower seal structure opening speed of the present invention.
3, lower end set taper hole bottom outer wall is provided with several radial opening groove, can radially sample.
