Abstract
The utility model discloses a continuous circulating-flow sampling device. The continuous circulating-flow sampling device comprises a water inlet tube, a water outlet tube, an adjusting valve, a sampling cup and a sampling tube, wherein the adjusting valve is arranged at the water inlet end of the water inlet tube; the outlet end of the water inlet tube is communicated with the inlet end of the water outlet tube by virtue of a pipeline; the upper part of the cup wall of the sampling cup is connected with one end of a sample inlet tube; the other end of the sample inlet tube is communicated with the outlet end of the water inlet tube; the bottom of the sampling cup is connected with one end of a sample outlet tube; the other end of the sample outlet tube is communicated with the inlet end of the water outlet tube; and the sampling tube is arranged above the sampling cup. The continuous circulating-flow sampling device has a simple structure, and is small in size and convenient to operate and manage. By using the continuous circulating-flow sampling device, the water inlet tube, the water outlet tube, the sample inlet tube and the sample outlet tube are mutually matched, so that a water sample in the sampling cup is continuously renewed to ensure that the water sample in the sampling cup is the same as the actual water source, and the water sample is so representative to guarantee the detection accuracy.
Description
Technical field
The utility model relates to the environment measuring field, relates in particular to the through-circulation sampler that a kind of water analysis is used.
Background technology
Water is the important component part of natural resources, is the material base that tellurian is rely and existed, and is the most important condition of maintaining ball ecological environment sustainable development and even human survival.Water has decisive meaning for biological and the mankind's existence.Yet; along with the development of society, water resource is suffered day by day serious pollution and destruction, and the contradiction between social sustainable economic development and water pollute is deepened day by day; the mankind's production and the healthy threat that also day by day is subject to the water pollution, fwaater resources protection has become instant mission and task.Along with the enhancing of fwaater resources protection consciousness, water quality detection work more and more comes into one's own, and the workload of water quality monitoring is corresponding increase also.Water quality is detected, must first carry out pre-service to test sample.Keep water sample character consistent with the water source, in time obtaining first-hand water source is the important prerequisite that guarantees detection accuracy.At present, the sampler major part in existing pretreatment unit all exists hoards water sample, the problem of the water sample that can not upgrade in time, and there is some difference and cause the accuracy of testing result to be affected to make water sample and actual water source.
The utility model content
The purpose of this utility model is as overcoming the defective of prior art, and a kind of simple in structure, volume is small and exquisite, water sample can upgrade in time through-circulation sampler is provided.
For achieving the above object, the utility model by the following technical solutions: a kind of through-circulation sampler comprises a water inlet pipe, a rising pipe, a variable valve, a sampling cup and a stopple coupon; Described variable valve is located at the entrance point of described water inlet pipe, and the endpiece of this water inlet pipe is communicated with the entrance point of rising pipe by pipeline; The wall of cup top of described sampling cup is connected with an end of a sample feeding pipe, and the other end of described sample feeding pipe is communicated with the water inlet pipe endpiece, and the end that the bottom of described sampling cup and goes out the sample pipe is connected, and the described other end that goes out the sample pipe is communicated with the entrance point of rising pipe; Described stopple coupon is located at the top of described sampling cup.
Specifically, but described stopple coupon is the sampling pipette of an oscilaltion.
Specifically, described sampling cup is funnel-form wide at the top and narrow at the bottom.
Specifically, describedly go out the end that the sample pipe is connected with sampling cup and be U-shaped bending.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, and volume is small and exquisite, convenient operation and management; The utility model is by water inlet pipe, rising pipe, sample feeding pipe and go out cooperatively interacting of sample pipe the water sample in sampling cup is constantly updated, and ensures that in sampling cup, water sample is identical with actual water source, thereby makes the more representative accuracy that ensures detection of water sample.
Description of drawings
Fig. 1 is the structural representation of the utility model continuous circulation sampler.
Embodiment
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment, the technical solution of the utility model is described further and illustrates.
With reference to Fig. 1, a kind of through-circulation sampler that the utility model provides comprises that a water inlet pipe 1, a rising pipe 2, a variable valve 3, a sampling cup 6, a sample feeding pipe 4, go out sample pipe 5 and a stopple coupon 7.The endpiece of described water inlet pipe 1 is communicated with the entrance point of rising pipe 2, and described variable valve 3 is located at the entrance point of described water inlet pipe 1, regulates by variable valve 3 water sample flow and the flow velocity that flows into water inlet pipe 1.Described sampling cup 6 is funnel-form wide at the top and narrow at the bottom, and the wall of cup top of sampling cup 6 is connected with an end of sample feeding pipe 4, and the bottom of sampling cup 6 is connected with an end that goes out sample pipe 5, goes out the end that sample pipe 5 is connected with sampling cup 6 and is U-shaped bending.The other end of sample feeding pipe 4 is connected with water inlet pipe 1 endpiece, and the other end that goes out sample pipe 5 is connected with rising pipe 2 entrance points.The water sample that enters in water inlet pipe 1 forms shunting at the endpiece of water inlet pipe 1, part water sample directly flows to rising pipe 2 along water inlet pipe 1, another part water sample is by flow through sampling cup 6 and go out sample pipe 5 and enter rising pipe 2 again of sample feeding pipe 4, converges and flows out from rising pipe 2 at two strands of current of entrance point of rising pipe 2.Described stopple coupon 7 be located at described sampling cup 6 directly over, but described stopple coupon 7 is the sampling pipette of an oscilaltion, when needing sampling, stopple coupon 7 is drawn a certain amount of water sample toward the liquid level that drops to sampling cup 6.Can make sampler form two-stage circulation according to the connected mode of above-mentioned pipeline and sampling cup 6, water sample in sampling cup 6 constantly upgrades the water in the cup sample after reaching the maximum storage amount, the interior water sample of sampling cup 6 and the water source of outside are consistent, water sample has more representativeness, thereby makes the accuracy of testing result higher.
The above only further illustrates technology contents of the present utility model with embodiment; so that the reader is more readily understood; but do not represent that embodiment of the present utility model only limits to this, any technology of doing according to the utility model is extended or recreation, all is subjected to protection of the present utility model.
