Description

Fluid sampling device under a kind of vacuum state
Technical field
The utility model relates to a kind of sampler, particularly fluid sampling device under a kind of vacuum state.
Background technology
Some chemical industry tail gas absorption plant needs to run in vacuum environment, in order to monitor the content of absorbing liquid, needs to sample from system to analyze.If sampling before carry out system emptying can affect production and inconvenient; If band vacuum sample; not easily take out and dangerous.Traditional vacuum sampler complex structure, needs the pressure differential that carries between vacuum balanced sampling device and sampling pipe thus samples, and cost is higher and operation is very inconvenient.
Utility model content
Technical problem to be solved in the utility model is to provide fluid sampling device under simple, the easy to operate vacuum state of a kind of structure.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Fluid sampling device under a kind of vacuum state, it is characterized in that: comprise sampling groove, top connection valve, bottom connection valve, atmospheric valve and sample valve, sampling groove is airtight cell body, sampling groove upper end is by upper end pipeline and vacuum liquid pipeline communication and top connection valve is arranged on the pipeline of upper end, sampling groove lower end is by lower channel and vacuum liquid pipeline communication and bottom connection valve is arranged in lower channel, sampling groove upper end is provided with exhausting pipeline, atmospheric valve is arranged on exhausting pipeline, sampling groove lower end is provided with sample tap, sample valve is arranged on sample tap.
Further, described sampling groove side has viewport, is provided with transparent window in viewport.
Further, described exhausting pipeline upper end is reclinate arc.
The utility model compared with prior art, have the following advantages and effect: under a kind of vacuum state, fluid sampling device structure is simple, with low cost, and by the cooperation of sampling groove, top connection valve, bottom connection valve, atmospheric valve and sample valve, tightly rely on the map function of valve, complete vacuum sample, easy to operate, sampling easily, prevents the danger that sampling with pressure likely causes; Sampling complete surplus liquid can retrieval system, does not need extra process, improves work site environments.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of fluid sampling device under a kind of vacuum state of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
As shown in the figure, under a kind of vacuum state of the present utility model, fluid sampling device comprises sampling groove 2, top connection valve 4, bottom connection valve 5, atmospheric valve 6 and sample valve 7, sampling groove 2 is airtight cell body, sampling groove 2 upper end to be communicated with vacuum liquid pipeline 1 by upper end pipeline and top connection valve 4 is arranged on the pipeline of upper end, sampling groove 2 lower end to be communicated with vacuum liquid pipeline 1 by lower channel and bottom connection valve 5 is arranged in lower channel, sampling groove 2 upper end is provided with exhausting pipeline, atmospheric valve 6 is arranged on exhausting pipeline, sampling groove 2 lower end is provided with sample tap, sample valve 7 is arranged on sample tap.
Sampling groove 2 side has viewport, is provided with transparent window 3 in viewport, can be observed the liquid sampling situation in sampling groove 2 by transparent window 3.Exhausting pipeline upper end is reclinate arc, by cambered design, can cushion emptying, avoids that air velocity is too fast causes loss of liquid.
By technique scheme, under a kind of vacuum state of the present utility model, fluid sampling device when in use, first closes atmospheric valve 6 and sample valve 7, open top connection valve 4 and bottom connection valve 5, makes sampling groove be placed in the circulation of band vacuum system; Observation window closes top connection valve 4 and bottom connection valve 5 after there is liquid, open atmospheric valve 6 and sample valve 7, sample according to general sampling procedure from sample valve 7; Close sample valve 7 after sampling, slowly open bottom connection valve 5, liquid is sent back in band vacuum system.The utility model is easy and simple to handle, and sampling easily, prevents the danger that sampling with pressure likely causes; Sampling complete surplus liquid can retrieval system, does not need extra process, improves work site environments.
Above content described in this instructions is only to the explanation of the utility model example.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment; only otherwise depart from the content of the utility model instructions or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
