Description of drawings
Fig. 1 measures the sectional view of sampler for the utility model
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further.
Divide upper, middle and lower three parts referring to cylindrical shell shown in Figure 1, the cylindrical shell upper top has a charging aperture and a densimeter measurement hole 1, and charging aperture is connected with by-pass valve control by flange, and by-pass valve control can be selected ball valve.Can control the flow that flows into the slurries of cylindrical shell by charging hole by the switch degree of adjusting control valve door.The cylindrical shell upper top can also be opened the situation that a spy-hole is observed cylindrical shell entoplasm liquid, and the spy-hole position depends on the needs.Have an overflow vent 2 on the barrel of cylindrical shell top one side, its distance apart from the cylindrical shell upper top depends on the needs, and can be 100 millimeters, and overflow vent 2 mouths of pipe can connect flexible pipe and pass to nearby trench.
PH instrumentation amount device is positioned at the cylindrical shell middle part, and it is measured and has four openings on the pipeline: two water inlets, a tap hole and a PH instrumentation metering-orifice 3.Tap hole and PH instrumentation metering-orifice 3 equal diameters and mutual UNICOM, its angle is 180 degree; Tap hole is downward, and the slurries that flow into from water inlet continuously outflow from tap hole, solidifies thereby guarantee to measure liquid that can not; PH instrumentation metering-orifice 3 makes progress, built-in PH potential electrode, and solid particles sediment is regularly discharged to the sampler bottom, thereby has well protected the PH probe.Two water inlets all with the mutual UNICOM of adapter pipeline at tap hole and PH instrumentation metering-orifice 3 places, the angle between the adapter pipeline at two water inlet places is greater than 180 degree; The adapter pipeline at the adapter pipeline at a water inlet place and tap hole and PH instrumentation metering-orifice 3 places is vertical mutually and be connected with cylindrical shell; The diameter of adapter pipeline that has angle and this water inlet place between the pipeline at the adapter pipeline at another water inlet place and tap hole and PH instrumentation metering-orifice 3 places is less than the diameter of the adapter pipeline at tap hole and PH instrumentation metering-orifice 3 places, when PH instrumentation buret road is stopped up because of the slurries sediment, be the accuracy that guarantees that pH value is measured, will introduce the adapter pipeline that clear water cleans PH instrumentation metering-orifice 3 places from this water inlet.
The cylindrical shell bottom has a drain 4, this drain 4 is connected with a ball valve by flange, by control ball valve switch degree, regulate the size that flows out the cylindrical shell slurry flow, thereby further regulate the size of inner barrel slurries pressure, make slurries pressure can be released into normal pressure, eliminated the impulsive force of slurries.
Connect by flange between cylindrical shell and the adapter.Cylindrical shell, flange and adapter material all adopt glass-reinforced plastic material, as FRP.This makes device anticorrosion antiwear, life-span long, the also corresponding raising of the compatibility of fluid medium.
