Abstract
The invention relates to an online weighing density sensor, which is characterized in comprising a protective cover, a measuring component arranged under the protective cover, and a measuring tube vertically arranged on the measuring component; wherein, a slurry inlet pipe passes above the measuring tube, a guide tube led out from a tee is inserted into a position near the bottom of the measuring tube, and an overflow port is arranged on the upper end of the measuring tube. When the level of the liquid to be tested is higher than the overflow port, the liquid under test will automatically flow out, so as to maintain the flowing liquid at a certain volume; the density of the liquid under test can be measured by means of the sensor. The invention has the advantages of no radiation source, no nuclear radiation and thus no harm to the construction staff, no direct contact between the sensor and the liquid for testing, resistance to pollution, convenient maintenance and high precision.
Description
Technical field
The invention belongs to liquid medium density proving installation technical field, particularly a kind of online weighing formula density sensor.
Background technology
In the engineering constructions such as present large and medium-sized power station, grouting works must use the job specifications of three parameters, systemic circulation grouting automatic recording instrument to put into effect in succession, and progressively carries out with the result standard of cement comsumption as grouting works.The process detection of dynamic of pressure, flow two parameters realizes substantially in the grouting automatic recording instrument at present.But the detection of the water cement ratio of cement grout (W/C) still rests on manual weighing's stage, and the water cement ratio data of demonstration and printing also are artificial the inputs in the self-recording device.
The online dynamic density sensor that uses mainly contains at present: nucleon density sensor and differential pressure type density sensor.
The nucleon density principle of sensors is when passing cement grout by the energetic gamma rays bundle, part ray is absorbed by slurries, another part ray passes slurries and is detected the device absorption, because water section and cement granules part is different to gamma-ray absorption coefficient in the slurries, absorb ray by analyzing detector, can calculate the density of slurries.Should fully carry out every anti-nuclear facilities, the distance of taking care during use at use nucleon density sensor.When measuring serum density, forbid to have foreign material and sediment in the pipeline in the use,, can cause the error of measurement to increase because foreign material are different to the absorption coefficient and the slurries of ray.
Differential pressure pick-up is density bucket and high-precision pressure sensor that adopts a level altitude.By sensor the information of the slurries in the density bucket is passed to vasculum, can obtain serum density by analyzing.This density sensor test pressure inductive head will with fluid to be measured directly contact contaminated easily, burn into is bad easily, precision fluctuation big.
Summary of the invention
The purpose of this invention is to provide the online weighing formula density sensor that a kind of Dynamic High-accuracy detects serum density.Can the dynamic any liquid medium density of online detection.And do not have radioactive source, no nuclear radiation does not have any harm to the workmen; Sensor does not directly contact with fluid to be measured, be difficult for contaminated, easy to maintenance, precision is high.
The present invention realizes that the technical scheme of its goal of the invention is: a kind of online weighing formula density sensor is provided, this sensor comprises protective cover, the measurement assembly is arranged at the bottom in the protective cover, measure to be placed with on the assembly and measure tube, pulp-inlet pipe passes through from measuring the tube top, utilize threeway to tell a mozzle and insert the position of measuring the nearly bottom of socket joint, the part slurries enter through mozzle and measure tube.Measuring the tube upper end has overflow vent, and when fluid to be measured exceeded overflow vent, fluid to be measured flowed out automatically, guaranteed the working fluid given volume.Can measure measured medium density through this sensor.
Online weighing formula density sensor principle of work: fluid to be measured is through out-of-date because the volume of measuring tube (v) constant, the special measurement assembly is measured quality (m), according to ρ=m/v, can draw measured medium density.
The invention has the beneficial effects as follows there is not radioactive source, no nuclear radiation does not have any harm to the workmen; Sensor does not directly contact with fluid to be measured, be difficult for contaminated, easy to maintenance, precision is high
Description of drawings
Fig. 1 is a synoptic diagram of the present invention, and Fig. 2 is along the sectional view of A-A direction among Fig. 1.
Among the figure: 1, protective cover, 2, spacing thimble, 3 measure tube, and 4, the mozzle valve, 5, pulp-inlet pipe, 6, threeway, 7, isocon, 8, mozzle, 9, valve, 10, overflow vent, 11, measure assembly, 12, clean-out opening.
Embodiment
As shown in Figure 1, the outside of online weighing formula density sensor is a protective cover 1, the protective cover inner bottom part is for measuring assembly 1, vertically be placed with on it and measure tube 2, the top of protective cover 1 has pulp-inlet pipe 5 to pass through, to be divided into isocon 7 and mozzle 8 by threeway 6, isocon inserts measures tube 2 outlets near the bottom of measuring tube, and overflow vent 10 is arranged at the top of measuring tube.
Slurries are entered by mozzle 8 and measure tube 2, and when the slurries height reached overflow vent 10, unnecessary slurries can overflow, and imported isocon 7, and the tested slurry volume of measuring in the tube 3 is (v) constant like this.Measure assembly 11 and measure the quality (m) of tested slurries,, can draw measured medium density according to ρ=m/v.
Because the slurries in the mozzle 8 are identical with the slurries in the pulp-inlet pipe 5 and flow synchronously, and the tested slurries of measuring in the tube 3 are also upgraded incessantly synchronously, so dynamically measure the density of slurries.
During fluid to be measured process density sensor, by mozzle valve 4, it is too little to regulate the fluid to be measured flow at any time.The mozzle lower end is provided with the buffer substrate tablet (not shown), in case flow velocity has impulse force to measuring tube bottom when too fast, influences measuring accuracy.
Run through protective cover 1, be provided with two groups of spacing thimbles 2, touch and measure tube 3, spacing to it, guarantee the sensor measurement precision.Fig. 2 is the sectional view at spacing thimble place.Spacing thimble also can only be provided with one group.
The bottom of protective cover 1 is provided with clean-out opening 12, is convenient to clean slurries and other impurity of falling into.
Mounted valve 9 on the isocon 7, the scalable slurry flow.
