Description of drawings
The structural representation of the preferred implementation of the water sampling device that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with accompanying drawing water sampling device and the water stabilization property detection system that the utility model provides is described in further detail.
Water quality stability mainly refers to chemical stability, and water quality stability often is defined as neither dissolving and not depositing lime carbonate in the water and wastewater industry fortunately.When the lime carbonate supersaturation in the water, tend to be settled out lime carbonate, this water can produce precipitation of calcium carbonate when flowing in pipeline, be deposited on to cause fouling on the tube wall.When calcium carbonate content is lower than saturation value in the water; then tend to make settled dissolution of calcium carbonate; this water runs into concrete pipeline and structures will produce erosion action; then can dissolve the protection of inner-walls of duct lime carbonate when flowing in metallic conduit touches; metal is produced corrosive attack, and the two all is the water of chemically unstable.Having only does not both have winnofil tendency and does not have the water that dissolving lime carbonate is inclined to yet and be only chemically stable water.
Stable index method is used for water quality stability and detects, it gathers detected water sample by the water sampling device, this water sampling device splits into two-way by shunt wherein with detected water sample, wherein one the road flow through the sampling post (being generally the tubing string that takes up calcium carbonate granule), another road is blank sample stream.Can judge water quality stability by measuring blank sample stream with the basicity changing value of the water of the stream of the sampling post of flowing through.
As shown in Figure 1, the water sampling device that the utility model provides comprises shunt 3 and sampling post 5, described shunt 3 has liquid inlet 9, first liquid outlet 11 and second liquid outlet 22 with shunt 3 internal communication, first liquid outlet 11 of described shunt 3 is connected to the inlet of described sampling post 5, this water sampling device also comprises sand core filter 2, and this sand core filter 2 is arranged on 9 places, liquid inlet of described shunt 3.
According to the technical scheme that the utility model provides, sand core filter 2 is arranged on 9 places, liquid inlet of shunt 3.Thus, detected water sample can be filtered by sand core filter 2 before by shunt 3 shuntings, will the impurity in the water sample and the suspension filtering after shunt again, make the flow through water sample of sampling post 5 pass through the filtering of impurity and suspension, reduced pollution to sampling post 5.
