Inside 310, and the bottom end 311 of chamber 310 is connect with liquid discharge passage 312.It is logical that said valve 330 is set to liquid discharge
On road 312, to control whether liquid discharge passage 312 is closed.
Chamber 310 is also connected to the detection entrance 410 of detection device 400, solenoid valve 350 by gas outlet channels 313
It is then set on gas outlet channels 313, control detection device 400 connects chamber 310 or external environment.In embodiment, detecting
Device 340 be set on chamber 310 and be electrically connected aforementioned electromagnetic valve 350 and detection device 400 (such as by conducting wire W), to
The water volume (such as can optically or the mode of contact liq detects liquid level) accumulated in detection chambers 310.
In the present embodiment, detection device 400 may be, for example, gas chromatograph or infrared ray instrument, have detection 410 He of entrance
Detection outlet 420 wherein detection outlet 420 is connect with the tube body 120 of vapor liquid equilibrium component 100, and pumps 500 and three-way valve 600
It is set between detection outlet 420 and tube body 120.In addition, three-way valve 600 also connects with aforementioned clean gas feeding mechanism 700
It connects.
Illustrate the liquid detecting system operation mode of the utility model below.Firstly, the liquid L to be detected is by filter plant
200 filtering after, can by liquid inflow port 150 enter hollow container 110 inner space 111, and by liquid outlet 160 from
Open aforementioned inner space 111.In general, the bottom end 113 of liquid level and hollow container 110 that liquid L is accumulated in inner space 111
Distance can be roughly equal with the distance between liquid outlet 160 and bottom end 113 D2, the end 121 of tube body 120 can enter liquid
In body L.
Then, the gas in detection device 400 can be driven by pump 500, sequentially pass through three-way valve 600 and tube body 121 enters
The inner space 111 of hollow container 110.Since the end 121 of tube body 120 is located in liquid L, into before hollow container 110
State after gas leaves tube body 120 by gas inflow entrance 180, can pass through liquid L and towards the gas discharge outlet of adjacent top end 112 170
Flowing.Therefore, the substance to be detected can be dissolved in These gases acceleratedly in liquid L, the gas-liquid concentration in hollow container 110
Balance can be reached in the short time.
The gas left by These gases outlet 170 will enter the chamber of gas-liquid separation component 300 along connecting tube 320
In 310.In the flow process along connecting tube 320, the temperature of gas can slightly decline, therefore have partial moisture from gas
Middle precipitation is simultaneously piled up in the chamber 310 of gas discharge outlet 170.Therefore, the moisture that can avoid being precipitated is directly entered detection device
In 400, to reduce the probability of the damage of detection device 400 and improve the precision of detection.
It is greater than one in advance when the aforementioned detector 340 of gas-liquid separation component 300 detects the water volume accumulated in chamber 310
If when volume, can communication number to solenoid valve 350, make the company of 350 disconnection detection equipment 400 and gas-liquid separation component 300 of solenoid valve
It connects, and transmittable signal makes detection device 400 stop detection to detection device 400.At this point, user can be such that valve 330 opens
It opens, the moisture accumulated in chamber 310 is discharged.On the contrary, the water volume accumulated in chamber 310 is default without departing from aforementioned
When volume, valve 330 is set off.
In the case that accumulation moisture is not out preset vol and the closing of valve 330 in chamber 310, gas can be by gas
Passing away 313 leaves chamber 310, and enters detection device 400 by detection entrance 410.Before detection device 400 can be by analysis
It states contained material proportion in gas and calculates the content of material in liquid L.
, can be by These gases by 420 discharge of detection outlet after the completion of detection device 400 detects, the gas after discharge can be again
It is secondary to be driven by pump 500, the inner space 111 of hollow container 110 is entered after three-way valve 600 and tube body 121, and follow again
Ring.
Due to the gas in liquid detecting system can when liquid L enters continual circulation, can continuously monitor
Content of material in liquid L can be effectively applied to various fluids.
After the completion of liquid detecting system detection, clean gas feeding mechanism 700 can provide clean gas (such as nitrogen),
Enter vapor liquid equilibrium component 100, after three-way valve to have the function that clear up pipeline.Likewise, detection device 400 can pass through
Solenoid valve 350 extracts gas by external environment, to supplement the gas and cleaning pipeline in pipeline.
In some embodiments, gas-liquid separation component 300 can omit detector 340 and solenoid valve 350.In some implementations
In example, liquid detecting system can omit gas-liquid separation component 300, and keep the gas discharge outlet 170 of vapor liquid equilibrium component 100 direct
The detection entrance 410 of connecting detection device 400.In some embodiments, pump 500 can be integrated into detection device 400.
In conclusion this creation provides a kind of liquid detecting system, due to vapor liquid equilibrium component in liquid detecting system
