Description
The utility model relates to a kind of improvement of chemical sensor caliberating device.
At present, industrial boiler feed water, steam etc. need be monitored water quality, operation when on-line measurement such as leading as high purity water dissolved oxygen DO, PH, electricity is demarcated, often adopt to place standard solution or air to demarcate sensor, be fixed on the commercial measurement device owing to sensor like this, when sensor passivation occurs and damages, need pull down activation and clean demarcation, both influenced accuracy, inconvenient again, and be difficult for realizing robotization control.
The purpose of this utility model provides a kind of cleaning that can sample processor be provided with sensor and demarcates the chemical sensitisation apparatus.
The utility model is made up of sensor, sample processor, cleaning calibrate valve, demarcation electrode, the sidepiece of sample processor is provided with stopple coupon, the outer setting of stopple coupon has positioning pipe, the arranged outside of positioning pipe has run-down pipe, the top of stopple coupon is provided with the gravity closing cover, the top of cover is provided with sensor at the bottom of the sensor, be provided with the cleaning calibrate valve in the runner of spinner-type flowmeter, the sidepiece of spinner-type flowmeter is provided with delivery pipe, above-mentioned each assembly is installed in the water sealed tank, demarcates electrode and is arranged in the circulation road of function seat; Be provided with filter screen in the stopple coupon.
It is simple to the utlity model has structural principle, can realize characteristics such as the fully automatic operation of online table is demarcated, and antifouling property is good.
Accompanying drawing 1 is a section of structure of the present utility model.
Accompanying drawing 2 is a vertical view of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described, structure of the present utility model and principle are to realize like this, one side of sample processor of the present utility model is provided with stopple coupon 1, test sample enters stopple coupon by positioning pipe 2 bottoms and with gravity closing cover 3 jack-up on stopple coupon top, test sample such as liquid enter in the run-down pipe 4 simultaneously, because run-down pipe is arranged in the water sealed tank 5, test sample is stored in the water sealed tank, test sample enters in the sensor cover for seat 6 by runner 9 simultaneously, in the runner in the sensor 7 contact back inflow spinner-type flowmeters 10 on cover for seat top, its top is provided with cleans calibrate valve 11, overflow part and flow in the delivery pipe 12, demarcate electrode and be arranged in the runner 9 of function seat 8.The utility model by after several times having enough to meet the need in the runner of sample processor, is accomplished test sample fully to isolate with outside air, makes the sample of sensor contact accurate, is provided with filter screen in stopple coupon, can be to detected sample filtering.Clean calibrate valve and the runner and the external world can be got in touch partition, and tested standard model is injected in the runner by cleaning calibrate valve, contact with sensor, with the detection performance of detecting sensor.By behind the sensor, the access function instrument detects the sample of required detection, and obtains accurate result the utility model with detected sample.
