Abstract
The utility model provides a sampling tool for detecting water quality. The sampling tool for detecting the water quality comprises a sampling tube, a needle-shaped sampling opening is arranged at the front end of the sampling tube, and a negative-pressure sampler is arranged at the rear end of the sampling tube. Compared with the prior art, the sampling tool for detecting the water quality has the advantages of being reasonable in design, simple in structure, convenient to use, and the like. Meanwhile, sampling process is safe and reliable, the water quality is not polluted easily, and accuracy of sampling results is ensured.
Description
Technical field
The utility model relates to the food hygiene field, specifically a kind of simple in structure, sampling instrument that water quality detection is used.
Background technology
Food hygiene is the aggregate measures for preventing that food pollution and adverse factor are detrimental to health and take.At present in the food hygiene detection process, there is larger difficulty in the sampling that fluid food products detects, adopt traditional glass tube to take a sample such as the samplings such as potable water, mineral water, dairy products are general, in the process of sampling, be easy to enter dust, introduce impurity, thus the judgement that result of laboratory test is made the mistake, and sampling operation is inconvenient, and stopple coupon is easy cleaning not.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of water quality detection sampling instrument simple in structure is provided.
The technical solution of the utility model realizes in the following manner:
The water quality detection sampling instrument, its structure comprises stopple coupon, described stopple coupon front end is provided with the needle-like sample tap, is provided with negative pressure sampler in the rear end of stopple coupon.Negative pressure sampler is used for and will be evacuated in the stopple coupon, and then stopple coupon sucks water sample by sample tap, because sample tap is arranged to needle-like, the water sample in the stopple coupon can not flow out from sample tap, guarantees the sample water withdrawal.
As improvement, be provided with vent valve between described stopple coupon and the negative pressure sampler.The effect of vent valve is that air passes through water and do not pass through, and so just can guarantee that the water sample in the stopple coupon can not flow in the negative pressure sampler, guarantees the accuracy of sampling result.
As preferably, described negative pressure sampler comprises flexible pipe, air bag, and the two ends of flexible pipe are connected with respectively stopple coupon, air bag, and the both sides, front and back of described air bag are provided with retaining valve.The technology of gasbag-type negative pressure structure is comparatively ripe, is easy to make.
As preferably, described flexible pipe is disposable use flexible pipe.Effective like this accuracy that guarantees sample result.
The beneficial effect that the utility model compared with prior art produces is:
Water quality detection of the present utility model with sampling instrument have simple in structure, easy to use, the characteristics such as be skillfully constructed, sampling process is safe and reliable, water quality is difficult for contaminated, guarantee the accuracy of sampling result, use procedure is comparatively convenient, and the hose length in the negative pressure sampler is adjustable, is applicable to the sampling of water quality of varying environment.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Mark in the accompanying drawing represents respectively:
1, retaining valve one, 2, air bag, 3, retaining valve two, 4, flexible pipe, 5, vent valve, 6, stopple coupon, 7, sample tap.
Embodiment
