Description

A kind of liquid sampler

Technical field

The utility model belongs to sampler and receives technical field, and in particular to a kind of liquid sampler.

Background technology

In process of production, very extensive to the sample detection of liquid, only due to most of tank bodies for containing liquid Upper opening can only take out when extracting liquid sample from tank body top end opening, measure result often because of top floating material or molten The factors such as liquid precipitate cause result to have deviation, it is desirable to be able to sampler be extend into liquid level or less and be sampled.

The Chinese patent of Publication No. CN203785924U discloses a kind of deep-layer liquid sampler, including liquid storage container, Further include being arranged in the liquid storage container lower end into drain pipe, it is described to connect into drain pipe upper end and the lower part of the liquid storage container Logical, lower end has into or out into leakage fluid dram for deep-layer liquid, and the liquid storage container is perpendicular to the cross section of upper and lower directions Rank street area of the product more than the inlet tube.Above-mentioned sampler realizes the discharge of control liquid by pressing, and is difficult to control liquid Discharge.

Utility model content

The utility model aim is to provide a kind of liquid sampler, convenient for carrying out liquid in the container for holding liquid Sampling.

To achieve the goals above, the utility model devises a kind of liquid sampler, including sampling container and set on taking The hollow pipe of sample container head, the hollow pipe bottom end are connected with sampling container top, and the sampling container lower face is equipped with First through hole, sampling container side wall are equipped with the second through-hole, and the second through-hole is equipped with port lid.

Further, further include the drain pipe for being set to sampling container bottom end, drain pipe top passes through first through hole and sampling Container is detachably connected, and drain pipe is equipped with control valve.

Further, the sampling container is cylindrical.

Further, the drain pipe is transparent material, and drain pipe side wall is equipped with scale.

Further, it is equipped with Anti-slip cover at the top of the hollow pipe.

The beneficial effects of the utility model：

The sampling container top is equipped with hollow pipe, and hollow pipe is externally provided with Anti-slip cover, can be held when carrying out liquid sampling Sampling container is stretched into liquid level or less and is sampled by firmly Anti-slip cover, when drain pipe is removed, by the second through-hole close, liquid from First through hole flows into or discharge；When drain pipe is connected, liquid is flowed into from the second through-hole, and the control valve on drain pipe is beaten It opens, liquid can be flow in another container, be may be implemented in sampling container by the way that control valve is arranged on drain pipe The quantitative discharge of liquid, convenient for pipetting liquid, the utility model has feature simple in structure, easily operated, easy to carry.

Fig. 2 is the schematic diagram after disassembling drain pipe in Fig. 1.

Specific implementation mode

The utility model is described in further details below in conjunction with the accompanying drawings, but the scope of protection of the utility model is not limited to This.

Embodiment 1

As shown in Figs. 1-2, the utility model provides a kind of liquid sampler, including 1 He of tubular sampling container It is fixedly connected on the hollow pipe 2 on 1 top of sampling container, 2 upper and lower opening of the hollow pipe and 2 bottom end of hollow pipe and sampling container 1 It is connected, the diameter of 1 cross section of sampling container is more than the diameter of hollow pipe 2, and first is equipped among 1 lower face of the sampling container Through-hole 11,1 side wall of sampling container are equipped with the second through-hole 12, and the second through-hole 12 is equipped with port lid（It is not marked in figure）, the present embodiment In, the second through-hole 12 is threaded hole, and hole covers and is equipped with external screw thread compatible with the second through-hole 12.

Liquid sampler described in the present embodiment further includes the drain pipe 3 set on 1 bottom end of sampling container, 3 top of drain pipe It is detachably connected by first through hole 11 and sampling container 1, specifically, the first through hole 11 is threaded hole, 3 top of drain pipe Equipped with external screw thread compatible with first through hole 11,3 cross-sectional diameter of drain pipe is less than the diameter of 1 cross section of sampling container, row Liquid pipe 3 is equipped with control valve 31, it is preferred that the longitudinal center line of hollow pipe 2 and the center of first through hole 11 coincide；Drain 3 bottom end of pipe is back taper,.

The drain pipe 3 is transparent material, and 3 side wall of drain pipe is equipped with scale.

2 top of the hollow pipe is equipped with Anti-slip cover 21.

The utility model can remove drain pipe 3, when that need not quantify drain by second there are two types of occupation mode Through-hole 12 covers port lid, and the liquid sampler is stretched into liquid level hereinafter, waiting for that liquid enters in sampling container 1, is pinned with thumb Hollow pipe top end opening takes out the liquid sampler vertically, and drain can be carried out by unclamping thumb.

Need quantitative drain when, drain pipe 3 can be connected to first through hole 11, removes the hole on the second through-hole 12 Sampling container 1 is stretched to liquid level hereinafter, liquid flows into sampling container 1 by the second through-hole 12 by lid, closing control valve 31 It is interior, after taking out sampling container 1, the liquid sampler is suspended from above container to be stored, adjusting control valve 31 carries out drain, Scale by observing 3 side wall of drain pipe can control lifting rate, realize quantitative drain.

The utility model can be sampled in different liquid, while can also be quantified and be discharged after sampling, and be had There is feature simple in structure, easily operated, easily fabricated.

The above is only the preferred embodiment of the utility model, and it does not limit the scope of the patent of the present invention, Equivalent structure or equivalent flow shift made by using the description of the utility model and the drawings, is directly or indirectly transported Used in other related technical areas, similarly it is included in the patent application protection domain of the utility model.
