Abstract
The utility model provides a circulation type device for on-line detection of pH electrodes. The circulation type device comprises a box body, a water inlet pipe, a drain pipe, a composite electrode, a filter screen, a tubular mesh seat, a water inlet valve and a drain valve. The circulation type device is characterized in that a tee is serially connected on a pipeline communicating a sampling pipe with the water inlet valve, the other end port of the tee is communicated with an excess flow valve through a pipeline, and the other end port of the excess flow valve is communicated with a tee serially connected between the drain valve and the drain pipe through a pipeline; a tee is serially connected on a pipeline communicating the water inlet valve with the water inlet pipe, and the other end port of the tee is communicated with a bypass valve through a pipeline. The circulation type device has the advantages that regular reverse excess flow cleaning can be performed in the box body to reversely clean the electrode and the filter screen to remove impurities, prolong the service life of the electrode and improve the detection precision.
Description
technical field:
The utility model relates to the flow type device of pH telegram detector, particularly a kind of online pH electrode detection.
background technology:
In sewage PH value on-line measurement application, the online pH value of general industry is measured its electrode mounting means and is all adopted sampling flow type device.From sampling pump outlet or from process pipeline sampling with pressure, as stopple coupon, be connected to this flow type device.
Flow type device is comprised of airtight box-like body, water inlet pipe, drainpipe, combination electrode, screen pack, tubulose reticulum, water intaking valve, draining valve.Water intaking valve one port is communicated with stopple coupon, water intaking valve another port is communicated with water inlet pipe, draining valve is communicated with drainpipe, box-like body bottom fixed water inlet pipe, on water inlet pipe, a tubulose reticulum is fixed in square chest bottom surface, on tubulose reticulum, along face, withhold the screen pack of a cap shape, combination electrode is arranged on case lid central authorities.Stopple coupon effluent stream crosses that water intaking valve, water inlet pipe, tubulose reticulum, screen pack are laggard to be entered in box-like body emptyly, and after combination electrode detects, input information detector shows, the sewage of the combination electrode of flowing through is discharged from drainpipe, draining valve.
The medium that contains particle and other impurity in sewage can be to the washing away and measuring cylinder produced to incrustation and pollute of electrode, and even impurity is bonded on electrode film, pH value is detected inaccurate, the serviceable life of simultaneously having reduced electrode.
summary of the invention:
The purpose of this utility model is to overcome above-mentioned defect, and a kind of flow type device of online PH electrode detection is provided.
Scheme of the present utility model is: comprise box-like body, water inlet pipe, drainpipe, combination electrode, screen pack, tubulose reticulum, water intaking valve, draining valve, it is characterized in that: on the pipeline being communicated with water intaking valve at stopple coupon, be connected in series a threeway, the another port of threeway and an excess flow valve pipeline connection, the triplate line being connected in series between the another port of excess flow valve and draining valve, drainpipe is communicated with; On the pipeline that water intaking valve, water inlet pipe are communicated with, be connected in series a threeway, this threeway another port and a bypass valve pipeline connection.
The utility model has the advantage of: in box-like body, regularly reverse overcurrent cleans, to electrode, screen pack reverse cleaning, removal of contamination, raising electrode life and accuracy of detection.
accompanying drawing explanation:
Fig. 1 is prior art structural representation.
Fig. 2 is the utility model structural representation.
embodiment:
The utility model comprises box-like body 3, water inlet pipe 8, drainpipe 5, combination electrode 4, screen pack 6, tubulose reticulum 7, water intaking valve 2, draining valve 9, it is characterized in that: on the pipeline being communicated with water intaking valve 2 at stopple coupon 1, be connected in series a threeway, the another port of threeway and excess flow valve 10 pipeline connections, the triplate line being connected in series between the another port of excess flow valve and draining valve 9, drainpipe 5 is communicated with; On the pipeline that water intaking valve 2, water inlet pipe 8 are communicated with, be connected in series a threeway, this threeway another port and bypass valve 11 pipeline connections.
Under normality, open water intaking valve 2, draining valve 9, close excess flow valve 10, bypass valve 11.During fixed time cleaning, close water intaking valve 2, draining valve 9, open excess flow valve 10, bypass valve 11, sewage oppositely enters box-like body 3 from excess flow valve 10, drainpipe 5 and cleans and wash away, from water inlet pipe 8, bypass valve 11 drainings.
