The demand that container different parts are sampled.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of fluid sampling device, and when sampling, which will not drip, spreads, Bu Huizao
At environmental pollution.And sampling is not easy to be mixed into other liquid.In addition it is possible to meet the need being sampled to container different parts
It asks.
A kind of fluid sampling device of the utility model, including sampler barrel, feed pipe and discharge nozzle, the sampler barrel upper end are opened
Mouthful, it is internally provided with piston, the opening that push-pull rod passes through the sampler barrel is connected with the piston, in the sampler barrel lower end
Diameter is less than other position internal diameters of sampler barrel, and its lower end two sides is connected with the feed pipe and the discharge nozzle respectively, described
Reversible check valve is respectively arranged in feed pipe and the discharge nozzle, the nozzle periphery of the discharge nozzle is provided with sample container
Interface, and nozzle end is located in sample container interface.
Further, the feed pipe and the discharge nozzle are set in the same horizontal position with sampler barrel linkage section.
Further, the feed pipe is Telescopic flexible pipe with liquid container linkage section.
Further, the feed pipe be removably connected to the feed pipe with liquid container linkage section with sampling
Cylinder linkage section.
Further, the sampler barrel, the feed pipe with sampler barrel linkage section and the discharge nozzle be glass or
Hard transparent plastic is made.
The beneficial effects of the utility model are:
Nozzle periphery in discharge nozzle is provided with sample container interface, discharge nozzle is directly connected into sample container, is made
It will not drip and spread when must sample, not will cause environmental pollution.By the way that reversible check valve is arranged in feed pipe and discharge nozzle, so that
Sampling is not easy to be mixed into other liquid.In addition, by setting Telescopic flexible pipe with liquid container linkage section for feed pipe, it can
Meets the needs of being sampled to container different parts.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the utility model embodiment.
Specific embodiment
To further illustrate each embodiment, the utility model is provided with attached drawing.These attached drawings are in the utility model discloses
A part of appearance mainly to illustrate embodiment, and can cooperate the associated description of specification former come the running for explaining embodiment
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and sheet are practical new
The advantages of type.Component in figure is not necessarily to scale, and similar component symbol is conventionally used to indicate similar component.
Now in conjunction with the drawings and specific embodiments, the present invention will be further described.
It is shown in Figure 1, a kind of fluid sampling device of the utility model, including sampler barrel 1, feed pipe 2 and discharge nozzle 3,
1 upper end opening of sampler barrel, is internally provided with piston 4, and push-pull rod 5 passes through the opening and the piston 4 of the sampler barrel 1
Connection, 1 bottom diameter of sampler barrel be less than other position internal diameters of sampler barrel 1, and its lower end two sides respectively with the feed pipe 2
Be connected with the discharge nozzle 3, be respectively arranged with reversible check valve 6 in the feed pipe 2 and the discharge nozzle 3, it is described go out
The nozzle periphery of expects pipe 3 is provided with sample container interface 7, and nozzle end 32 is located in sample container interface 7.
In the present embodiment, in order to which liquid is easy to flow into discharge nozzle 3, the feed pipe 2 and the discharge nozzle 3 from feed pipe 2
Be set in the same horizontal position with sampler barrel linkage section 21/31.
In the present embodiment, in order to meet the needs of being sampled to container different parts, the feed pipe 2 holds with liquid
Device linkage section 22 is Telescopic flexible pipe.
In the present embodiment, the feed pipe 2 with liquid container linkage section 22 be removably connected to the feed pipe 2 with
Sampler barrel linkage section 21 so that be conveniently replaceable feed pipe 2 with liquid container linkage section 22.
In the present embodiment, in order to which the present apparatus is not easy to be corroded, the sampler barrel 1, the feed pipe 2 are connect with sampler barrel
Section 21 and the discharge nozzle 3 are that glass or hard transparent plastic are made.
Sampling process is as follows:
1. adjusting length and the position of Telescopic flexible pipe 22, Telescopic flexible pipe 22 is placed in liquid container and needs to obtain
The position of sample；
2. (feed pipe check valve direction is discharge, out in the direction of the reversible check valve 6 of change feed pipe 2 and discharge nozzle 3
Expects pipe check valve direction is sucking), by 5 movable piston 4 of push-pull rod, empty the present apparatus；
3. change the direction of the reversible check valve 6 of feed pipe 2 and discharge nozzle 3, (feed pipe check valve direction is sucking,
Discharge nozzle check valve direction is discharge), by 5 movable piston 4 of push-pull rod, it is sampled；
4. emptying the present apparatus again after sampling；
5. being cleaned with clear water to the present apparatus.
A kind of fluid sampling device of the utility model is provided with sample container interface by the nozzle periphery in discharge nozzle 3
7, discharge nozzle 3 is directly connected into sample container, is spread so that will not be dripped when sampling, not will cause environmental pollution.By in feed pipe 2
With reversible check valve 6 is set in discharge nozzle 3 so that sampling be not easy to be mixed into other liquid.In addition, by by feed pipe 2 with
Liquid container linkage section 22 is set as Telescopic flexible pipe 22, can satisfy the demand being sampled to container different parts.
Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art is answered
