Abstract
The utility model relates to a switch constant voltage subassembly on calibration flow path and measured flow way in online water monitoring instrument. Its aim at increases the calibration and switches the function with the measured flow way outside the constant voltage effect of subassembly, save dedicated calibration structure. It is including mixing piece, overflow cup, overflow pipe, demarcation pole. The pole is markd through the push -and -pull to the structure, realizes its function of switching calibration, two kinds of flow paths of measurement. Under the calibration flow path, the water sample that awaits measuring can not get into the measuring cup, and when switching to the measured flow way, calibration liquid can not get into the measuring cup. Thereby save dedicated calibration structure, only use structure.
Description
Technical field
The utility model relates to a kind of structure that can switch calibration in online water monitoring instrument, measure the constant voltage assembly of two kinds of streams, especially switches the structure of two kinds of streams.
Background technology
At present in in-line meter structure, calibration stream with measure stream and be mostly two structures of separating, complicated operation, take up room greatly, the many possibilities that also can increase seepage of parts of use.
Utility model content
In order to solve the problem, the utility model adopts demarcates bar by increasing by one in the constant voltage assembly of the only way which must be passed at water sample to be measured, and structure and operation are simplified, and save the space of calibration application specific architecture, decreasing parts thus decrease seepage may.
Switch the constant voltage assembly of calibration stream and measurement stream in a kind of online water monitoring instrument in the utility model, described constant voltage assembly comprises mixed block, overflow cup, run-down pipe, demarcation bar; Described overflow cup and run-down pipe are fixed in mixed block, demarcate bar and are arranged in mixed block, fixed by plug.
When being shifted onto at the bottom of stroke by demarcation bar, the measurement stream of instrument switches to calibration stream, during the circulation of calibration stream, treats that test sample water can not enter into measuring cup, but directly overflows instrument by overflow cup and run-down pipe; When demarcation is pulled out at the bottom of the stroke other end, calibrating indicating instrument stream switches to measurement stream, when measuring stream circulation, treats that first test sample water enter mixed block, overflow cup is entered by mixed block, again enter mixed block by overflow cup, finally flow into measuring cup by mixed block, under this stream state, calibration solution can not enter in mixed block, in the process, sample water directly can not enter measuring cup from mixed block, but flows into measuring cup again via after overflow cup.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation that the utility model switches to calibration stream.
Fig. 3 is that the utility model switches to the structural representation measuring stream.
Fig. 4 is the structural representation of the utility model acceptance of the bid fixed pole.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, the utility model comprises overflow cup 1, run-down pipe 2, mixed block 3, demarcation bar 4, titer joint 5, pollution discharge joint 6, water inlet water sample joint 7.Overflow cup and run-down pipe are fixed in mixed block, demarcate bar and are arranged in mixed block, fixed by plug.
As shown in Figure 2, when being shifted onto at the bottom of stroke by demarcation bar, the measurement stream of instrument switches to calibration stream, and now, the calibration solution entrance in mixed block is communicated with water delivering orifice, and sample water inlet to be measured and water delivering orifice disconnect.Calibration solution enters mixed block from the calibration solution entrance of mixed block, through demarcating the space vacated in the middle of bar, flowing in stream hole public in mixed block, finally flowing out mixed block from water delivering orifice, flowing into measuring cup.Now treat that test sample water can not enter into measuring cup, but enter overflow cup, when water sample height exceedes run-down pipe, flow out instrument from run-down pipe.
As shown in Figure 3, when demarcation being pulled out at the bottom of the stroke other end, calibrating indicating instrument stream switches to measurement stream, and now, the water sample water inlet to be measured of mixed block is communicated with water outlet, and calibration solution entrance and water delivering orifice disconnect.Treat that first test sample water enter mixed block, after entering overflow cup by mixed block, reenter mixed block from overflow cup, through demarcating the space vacated in the middle of bar, flowing in stream hole public in mixed block, finally flowing out mixed block from water delivering orifice, flowing into measuring cup.When water sample pressure becomes large, the water level in mixed block rises, and the water of upper emersion is flowed out by run-down pipe, and the hydraulic pressure in this way in visual overflow cup is constant voltage.Under this stream state, calibration solution can not enter in mixed block, and in the process, sample water directly can not enter measuring cup from mixed block, but flows into measuring cup again via after overflow cup.
Obviously, those skilled in the art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if belong within the scope of the utility model claim and equivalent technology thereof to these amendments of the present utility model and modification, then the utility model is also intended to comprise these change and modification.
