Embodiment

Below in conjunction with accompanying drawing and embodiment, the utility model is further described.

As shown in Figure 1, a kind of anti freezing solution charging machine simple calibrating device, it is applicable to the on-line proving to the three-in-one charging machine in order to power-assisted oil of annotating, anti freezing solution, air window washing liquid used in automobile production process, to guarantee that each adding amount of charging machine is within the scope of the upper and lower limit of specified adding amount.This caliberating device specifically comprises a support 1, is arranged on a filling tank 2 of frame upper, is arranged on the tank prover 3 of mid-stent and is arranged on the fluid reservoir 4 of support bottom.For ease of being connected with the filling head of charging machine, we need to arrange a fill adapter 21 that can be connected with the filling head of charging machine on the top of filling tank, meanwhile, a liquid discharging tube 22 be connected with the top of tank prover is set in the bottom of filling tank, liquid discharging tube is arranged first valve 23 again, demarcate the liquid in filling tank is discharged in tank prover.In addition, arrange a collector tube 31 be connected with the top of fluid reservoir in the bottom of tank prover, collector tube is provided with the second valve 32, is stored in fluid reservoir to be concentrated by the liquid in tank prover, thus convenient recycling of demarcating rear liquid.In addition, we also need arrange transparent liquid injection pipe 5 at the side of tank prover vertically, the lower end of liquid injection pipe is connected with the sidewall of tank prover bottom, and liquid injection pipe sets gradually upper limit calibration loop 6 and lower limit calibration loop 7 from top to bottom, and first, second valve wherein can adopt ball valve.

The utility model needs first to carry out adjustment to the upper limit calibration loop on the liquid injection pipe of tank prover side and lower limit calibration loop before starting demarcation, and to determine upper limit calibration loop and the tram of lower limit calibration loop on liquid injection pipe, concrete alignment step is as follows:

The first step, we first close the second valve, then in a graduated standard measuring cup of tool, pour the liquid of required filling into, adding amount is the specified lower limit adding amount of charging machine, then the liquid in measuring cup is poured in tank prover by the opening of liquid injection pipe, then move up lower limit calibration loop, the coboundary of lower limit calibration loop is made to aim at liquid level in liquid injection pipe, the liquid level of liquid injection pipe corresponding when can determine to inject in tank prover the specified lower limit adding amount liquid of charging machine;

Second step, open the second valve, liquid in tank prover is all discharged in the fluid reservoir of bottom, and again close the second valve, in measuring cup, now pour the liquid of required filling into, adding amount is the specified upper limit adding amount of charging machine, then the liquid in measuring cup is poured in tank prover by the opening of liquid injection pipe, then upper limit calibration loop is moved down, make the liquid level in the lower limb aligning liquid injection pipe of upper limit calibration loop, the liquid level of liquid injection pipe corresponding when can determine to inject in tank prover the specified upper limit adding amount liquid of charging machine, thus complete the adjustment program before demarcation.

Then we can start to demarcate charging machine, particularly, first the filling head of charging machine is connected with the fill adapter on filling tank, then closes the first valve and the second valve, make between filling tank, tank prover, fluid reservoir mutually isolated, filling tank forms a closed tank.Then on charging machine, arrange specified adding amount, now open charging machine, first filling tank vacuumizes by charging machine, then in filling tank, injects liquid.Complete and annotate Deng charging machine and after separating filling head, open the first valve, namely the liquid in filling tank flow in tank prover by liquid discharging tube, can be seen the liquid level height of liquid in tank prover by the liquid injection pipe of tank prover transparent sides easily.If now during the section of liquid level between the upper limit calibration loop lower limb and lower limit calibration loop coboundary of liquid injection pipe, namely show that the adding amount of charging machine is in normal range, working properly continuation uses charging machine.Otherwise, then show that adding amount is less than or more than the adding amount required, charging machine needs to be serviced adjustment.After completing demarcation, open the second valve, the liquid in tank prover can flow into the interior storage of fluid reservoir of bottom completely, and like this, tank prover can again for the demarcation to charging machine.

After completing repeatedly demarcation, more liquid is have accumulated in fluid reservoir, the conveniently recycling of liquid in fluid reservoir, we can arrange an electronic drawing liquid pump (not shown) on fluid reservoir, and the delivery outlet of electronic drawing liquid pump is connected with the liquid storing barrel of charging machine by pipeline.Like this, we can open electronic drawing liquid pump and be sent back in the liquid storing barrel of charging machine by the liquid in fluid reservoir, to re-use.Certainly, we can arrange corresponding liquid level sensor in fluid reservoir, and when the liquid in fluid reservoir arrives a certain amount of, liquid level sensor can send signal, to control the automatic operation of electronic drawing liquid pump by corresponding controller.

In addition, as shown in Figure 2, we at the obconic liquid receiving port 53 of upper end open place grafting one of liquid injection pipe, fully can pour the liquid in measuring cup into liquid injection pipe to facilitate, thus be conducive to improving the precision of demarcating, be convenient to the installation of upper and lower limit calibration loop on liquid injection pipe simultaneously.

Further, the taper shape of evagination can be made in the bottom surface of filling tank and tank prover by us, and liquid discharging tube is then arranged on the center bottom filling tank, and collector tube is then arranged on the center bottom tank prover.Like this, when we open the first valve, the liquid in filling tank can flow in the tank prover of below rapidly completely, and the bottom surface of filling tank can not residual liquid, thus the adding amount can guaranteeing charging machine is completely the same with the amount of liquid entered in tank prover, to guarantee the accuracy of demarcating.After once demarcation terminates, when we open the second valve, liquid in tank prover can flow in the fluid reservoir of below equally rapidly completely, the bottom surface of tank prover does not have residual liquid, thus it is completely the same for the amount of liquid demarcated to guarantee that next timing signal charging machine injects in amount of liquid in filling tank and tank prover, and then ensure the precision of demarcation.

In order to make the liquid in filling tank produce bubble when being flowed in tank prover by liquid discharging tube, liquid discharging tube can be passed the upper wall of tank prover and to downward-extension, make the bottom surface of lower end near tank prover of liquid discharging tube by us.Then, the hook solid of the lower end of liquid discharging tube upwards arc bending semicircular in shape again, liquid discharging tube lower ending opening now just upward.Like this, when the liquid in filling tank is entered in tank prover by liquid discharging tube, the liquid that liquid discharging tube lower end opening upward flows out first upwards, and then refluxes downwards naturally.In the incipient stage, liquid in tank prover is less, now the liquid of backflow downwards naturally can flow along the bottom surface of tank prover, thus greatly can reduce the impact effect of liquid and tank prover bottom surface, thus liquid can be avoided to form bubble when impacting tank prover bottom surface.When the opening of the liquid level in tank prover higher than liquid discharging tube, the liquid flowed out in liquid discharging tube makes the liquid level in tank prover steadily raise from the bottom to top, that is, the liquid flowed out in the opening of liquid discharging tube can not be formed with the liquid in tank prover and impact and splashing effects, thus can effectively avoid producing bubble, and then guarantee stability and the accuracy of liquid level in liquid injection pipe, to improve the precision of demarcation.

Finally, as shown in Figure 2 and Figure 3, for the ease of moving and locating upper limit calibration loop and lower limit calibration loop, the pipe that liquid injection pipe can adopt transparent plastic to make, arrange along the axially extended edge strip 51 of liquid injection pipe to the symmetria bilateralis of liquid injection pipe, the lateral surface of both sides edge strip is the face of cylinder, thus makes the xsect of edge strip be circular arc.In addition, we also need arrange external thread on the lateral surface of edge strip, certainly, the lateral surface of both sides edge strip should be the face of cylinder of same axis, correspondingly, the medial surface of upper and lower limit calibration loop then arranges internal thread, thus upper and lower limit calibration loop is threaded on the external thread of liquid injection pipe both sides edge strip.When our forward and reverse rotation upper and lower limit calibration loop, under the external thread effect of both sides edge strip, upper and lower limit calibration loop can move up and down along liquid injection pipe, and can locate voluntarily when stopping operating.Be appreciated that and be, we also can arrange the set nut 52 on an external thread being threaded in both sides edge strip respectively in the downside of the upside of upper limit calibration loop and lower limit calibration loop.When upper and lower limit calibration loop moves into place, we can tighten two set nuts, make it to compress upper and lower limit calibration loop, thus can avoid upper and lower limit calibration loop because loosening automatic moving.

For the ease of the observation to height of liquid level in liquid injection pipe, we can place the buoy 8 of a cylindrical shape in liquid injection pipe; should leave gap between buoy and liquid injection pipe inwall, and arrange the vertical through hole 81 of a through lower surface at the center at buoy upper surface.Like this, when in tank prover during influent, the liquid in liquid injection pipe can promote buoy synchronous on move.When our upper limit calibration loop on the liquid injection pipe to tank prover side and lower limit calibration loop carry out adjustment, first can pour the specified lower limit adding amount liquid of charging machine into measuring cup in liquid injection pipe as previously mentioned, liquid enters in tank prover by the through hole at buoy center, then move up lower limit calibration loop, makes the coboundary of lower limit calibration loop aim at the upper surface of buoy in liquid injection pipe.Then in liquid injection pipe, the specified upper limit adding amount liquid of charging machine is poured into measuring cup again, liquid enters in tank prover by the through hole at buoy center, then upper limit calibration loop is moved down, make the lower limb of upper limit calibration loop aim at the upper surface of buoy in liquid injection pipe, the adjustment program before demarcation can be completed.And need to carry out timing signal to charging machine, we judge that whether charging machine is working properly by the height equally by observing buoy upper surface in liquid injection pipe, if the upper surface of buoy is between the lower limb and the coboundary of lower limit calibration loop of upper limit calibration loop, then illustrate that charging machine is working properly, otherwise then show that adding amount is less than or more than the adding amount required, charging machine needs to be serviced adjustment.
