Description
Technical field
The utility model belongs to the technical field more particularly to a kind of double-U-shaped scale siphon pipe that liquid layered measures.
Background technique
Currently, the prior art commonly used in the trade is such that
When measuring and analyzing for liquid type raw materials for production (such as beverage, drinks, Chinese medicine, chemical industry) sampling, usually
It needs to take out a small amount of liquid from big quantity of fluid as sample and be detected.In the prior art, tubular type sampling, benefit are carried out to liquid
With liquid internal and external pressure difference, so that liquid is entered collector from tube sampler and realize sampling.The formation of pressure difference is divided into artificial squeeze
Pressure type, extraction type and motor machine pump pressure type.
In conclusion problem of the existing technology is:
(1) manual compression formula or the shortcomings that extraction type sampling operation are accurate to sampling liquid level depth accuracy and sampling amount
The controllability of degree is poor, and sampling amount is less, can only multiple spot mixed sampling, can not accomplish different liquid level flood continuous samplings.
(2) separating liquid needs external connection power to pump when motor machine pump pressure type samples, and adjusting operation is relatively complicated, for a small amount of
Fluid retention can not utilize in sampling sampling pipe, cause the pollution and waste of lower sub-sampling.
(3) the suspension Stratified Sampling (such as soil mechanical composition measurement) more demanding for manipulation accuracy, is usually adopted
Different depth liquid is drawn with direct suction, needs that suction pipe height is fixed and adjusted with bracket in operating process, separating liquid needs external
Kinetic pump extracts, and downward, container bottom precipitating particle easily blocks pipeline to general suction pipe nozzle when drawing liquid.In microtest
It is required to meet the accuracy of liquid layered measurement and suction pipe easy to operate.
Summary of the invention
The main purpose of the utility model is to provide a kind of double-U-shaped scale siphon pipe, the technical problem to be solved is that
The continuous sampling that can carry out liquid different depth level, it is more demanding to the accuracy, accuracy and control of sampling,
And it is easy to practical operation.
The utility model is realized in this way a kind of double-U-shaped scale siphon pipe is provided with the first U-tube, described first is U-shaped
The water outlet of pipe is connected to straight tube, and the upper end of the straight tube is connected to the second U-tube；
The water outlet of second U-tube is connected to hose, is set with water check valve on the hose.
For opening or stopping siphon diverted liquid, easily controllable split-stream sampling amount
Clip is installed in second U-tube.
Facilitate fixed installation of second U-tube on the containers such as beaker by installing clip.
Graduated scale is provided on the outer wall of the straight tube.
Liquid level on straight tube is observed by the way that setting graduated scale is convenient.
The end of the hose is connected to water pump, and the water outlet of the water pump is set with flowmeter.
The speed and effect that absorption is improved by installing water pump realize the system to absorption flow by installation flowmeter
Meter.
The water inlet pipe nozzle of first U-tube is equipped with filter screen.
It is realized by installation filter screen to the filtering of absorption liquid, impurity is avoided to enter in sample.
The middle part setting of the clip is fluted, and anti-slip layer is equipped in the groove.
It is convenient that clip is supported by the way that groove is arranged；Anti-skidding effect is realized by the way that anti-slip layer is arranged, and is increased steady
It is qualitative.
In conclusion advantages of the present invention and good effect are as follows: the double-U-shaped scale siphon pipe can be realized to manipulation accuracy
In more demanding suspension Stratified Sampling, the second U-tube is supported by clip, and the position by adjusting clip is real
Now to the adjusting of the second U-tube height；By being provided with graduated scale on the outer wall of straight tube, it can be achieved that needing in microtest
It can satisfy the accuracy of liquid layered measurement and require easily to operate.
