SU112606A1 - Weighing dispenser for liquid flow meters - Google Patents

Description

The weigher is designed for working with liquid continuous flow meters. The device allows you to adjust the meter depending on the change in the flux value of the liquid being measured, 10 is taking into account the weight of the latter.

The proposed device differs from the known continuous continuous flow of the liquid to be measured, the absence of bottle cylinders and valves, as well as the lack of kinematic connection of the float, which makes a density correction with the rest of the device parts at the moments of release and float of the float.

The drawing shows schematically the device in two projections

The weigh dispenser is driven by a roller / meter.

Two identical pinions 2 rotate on the instrument shaft in different directions, which in turn control the movement of the mechanism for cutting off the measured doses of fluid.

This mechanism is designed as a rocker arm 3, carrying roller 4 at its end, sliding along some movable (but fixed during the running-in) direction 5.

The roller controls the coupling of the rocker arm 6 with the appropriate bristles, due to which a variable multi-directional swing of the rocker arm and, as a result, the cut-off of the doses is carried out.

Depending on the position of the controllers, the cut-off is made earlier or later. The position of the guides is regulated by a device such as a densimeter.

This device is represented by pon. 7, p.mavayuschiy in the pipe S, which receives the measured liquid. The lift height of the float corresponds to the density of the liquid, as a result of which the position of the guides and, accordingly, the frequency of dose cut-offs, is proportional to the density of the liquid to be measured.

At the moment of operation of the dispenser, the position of the float is fixed by a special clamp 9, which is activated when the charging hose is removed from the hook W. The counting of the dispenser is recorded by the counter //.

Due to the continuous (continuous) operation of the device and the absence of measuring tanks, as well as intermediate shut-off valves and valves, the dosage process is accelerated and becomes MORE Accurate due to the fact that changes in the density of the measured liquid are taken into account.

PRIOR DIRECTORSHIP and

1. A weight metering unit for liquid meters, which automatically shut off doses of light petroleum products using a rotary beam device, the frequency of movements of which is controlled by the position of the roller along which the roller associated with the rocker rotates. u and with the fact that, in order to accelerate the dosage of the irocca, a key was used, instantly changing the direction of the movement of the nrp adhesion to one of the two gears. rotating in different directions, which ensures continuity of the dosage.

2. Weight dosing on and. 1, because of the fact that, in order to reduce the nestingness of the device, a float was used, floating freely at the beginning of the dosage and locking when the screw was removed from the hook, so that it was automatically determined by the position of the pad the position of the guides, which makes an adjustment to the weight (density) of the fluid.
