Below principle of work of the present invention is described further:
By moulding pipe I 1-6 water sampling, through the filtration of filtration core 1-2 after inflow filter 1, filtrate flows into constant-current device 2 by moulding pipe II 4, and discarded water after filtration water check valve 1-5 flows into drainpipe 5, water sample collects in constant-current device 2 inside, and keeps constant liquid level.If the too fast flow of flow velocity is excessive, in surge chamber, liquid level exceedes the top overflow vent of run-down pipe 2-3, run-down pipe 2-3 will be flowed into and guiding system, water in surge chamber is because liquid level difference flows into measurement mechanism 3 by self gravitation from moulding pipe III 2-1, thus the water sample realizing flowing out remains in a constant pressure and flow rates.First the water sample flowed in measurement mechanism 3 passes through the survey sensor 3-5 in the right measuring chamber of the first liquid flow measurement groove 3-10, when entering left measuring chamber by collecting tray 3-8, collecting tray 3-8 collects the liquid flow through in measuring chamber, footpath of being circulated by liquid diminishes and makes liquid accelerate through sensor probe, the precision of chlorine residue/chlorine dioxide sensor practical herein by the impact of measuring solution flow rate, can arrange collecting tray to improve measuring accuracy.Bubble in liquid can be assembled at the first liquid flow measurement groove 3-10 top and be expelled to constant-current device 2 by deaeration pipe 3-9.Liquid flows into the second liquid flow measurement groove 3-4 from the first liquid flow measurement groove 3-10 by moulding pipe IV 3-2, in the second liquid flow measurement groove, after the measurement of survey sensor 3-5 in right measuring chamber, flow into left measuring chamber and promote float 3-3 with the flow velocity of liquid in reactive system intuitively, flowing into drainpipe 5 finally by moulding pipe IV 3-2, liquid unnecessary in measuring chamber can be discharged by the measurement water check valve 3-7 of liquid flow measurement trench bottom when the system is shut down.
The inlet that filtration unit is connected with pipeline have employed thin and flexible tube, avoid sample because transmitting the measurement delay caused, Open Side Down for filter core, retain particle larger in fluid, and increase along with constantly assembling gravity, and be deposited on the bottom of filtration unit, discharge by the filtration water check valve opening bottom at any time.
In two liquid flow measurement grooves, chlorine residue/chlorine dioxide sensor, pH survey sensor, temperature sensor and suspended body flowmeter are installed respectively in measurement mechanism.In pipeline, the circulation style of fluid ensures that measurement mechanism inner sensor is immersed in water body all the time; The installation screw thread of apparatus design and various sensor matching, and keep the convenience of its dismounting and change and maintenance; The indicating device wherein formed from gravity-type flow float and indicating graduation makes flow velocity intuitively, thus makes device have the visuality of flow velocity.Dissolved gas in fluid can discharge gas when pressure reduces and temperature rises, the accumulation in time of these gases can be full of measuring chamber, because the composition of gas differs widely with the composition measuring liquid, if sensor measurement portion has bubble, the accuracy of measured value can be affected, so must discharge.This device utilizes the thin pneumatics power that in the surge chamber of constant-current device, overflow produces, and makes gas discharge measuring chamber along the deaeration pipe be directly connected with constant-current device, ensures the normal work of sensor.Drained by the measurement water check valve opening below when measurement mechanism inside occurs that tiny particle gathers, or carry out debugging operations if desired.
The drainpipe of larger caliber is by the debugging of all each points and run the outside that current carry out gathering discharge system.
Whole system can be fixed on wall or in rack by substrate and form a whole system, and installation is very convenient.
