Device for the measured disposal of liquids

The invention relates to a device for the measured dispensing of liquids from a container with a measuring device charged with the interposition of a pump.

Modern devices for dispensing liquids, such as hydrocarbons, in particular from Containers mounted on trucks generally have a pump which cooperates with a meter which is a display instrument and includes a printer. The delivery can be interrupted for each delivered amount, with -ein at the same time Certificate is produced, part of which can be given to a customer and another part to the supplier is kept.

The delivery can be done through a flexible hose for deliveries with small flow rates and at Large flow deliveries through a flexible pipe.

To protect against fraud, it is not possible to provide two exits in the container, one of which is with the device for dispensing through the flexible conduit and the other with the device for dispensing through the flexible hose is fitted; such a system is prohibited.

The invention is based on the object of providing a device for the measured dispensing of liquids through to create two different lines, starting from a single outlet of a container ^, in which for each Correct measurement is ensured.

Based on a device of the type described at the outset, this object is achieved according to the invention in that that for the device a volume measuring device which cooperates with a display instrument and a printer, the one have a common zero reset device, and a downstream of the volumetric meter / three-way valve with two Outputs belongs, which has a locking device controlled by the zero reset device, so that during any change in the outcome is prevented after a transfer.

The invention also includes the following devices:

a) The three-way cock is operated in such a way that its two outlets are never connected to one another; this happens in particular by means of a cock plug or a switching element which is designed as a 90 ° elbow is rotatable about the axis of one of its outputs

b) the three-way valve is controlled in such a way that for each output one closed and one open Position is possible, the locking only preventing the transition from one exit to the other;

c) the locking device has a finger which slides in the body of the three-way tap and with one of the Switching member worn stop cooperates, the finger withdrawing at the moment of unlocking;

d) the mechanical connection between the zero reset device for the display instrument and the printer and the three-way valve has a Bowden cable which is on the locking finger acts;

e) the unlocking position corresponds to a central area when the control of the display instrument is reset to zero and printer.

The invention is illustrated below with reference to schematic drawings for example and explained with further details.

Show it:

1 shows a diagram of a device according to the invention;

FIG. 2 is a side view, partially cut away and in section, of an exemplary embodiment; FIG.

FIG. 3 shows a sectional view of the device according to FIG. 2.

According to FIG. 1, the device cooperates with a container 1 which is equipped with a valve 2, a filter 3, a pump 4, a separator 5 and other suitable devices is provided, and has a volume measuring device 6, which is equipped with a Indicating instrument 7 and a printer 8 cooperates, which have common zero reset device 9, and further contains a three-way valve 1o which is arranged downstream of the measuring device 6 and an outlet 11 for a flexible line 12 with a large diameter and an outlet 13 for a hose 14 provided with a dispensing tap 15. The three-way cock is provided with a locking device 16, which under

Interposition of a link 17 from the zero reset device 9 of the display instrument 7 and printer 8 is controlled so that during a dispensing of liquid any change in the output is prevented. A check valve is denoted by 29.

The function of the device is as follows:

A user pushes a ticket into a slot 18 of the printer 8 and performs , for example, a half turn of the hand lever 9 'of the zero reset device. In this position, the locking device is released and the user can operate the three-way valve 1o by means of a handle 19 and choose between delivery through the flexible hose 14 or the flexible line 12. When he has done this, he turns the handle 9 ¹ another half turn. The three-way tap is locked, the ticket is set, the first character is printed. Start the kaim delivery.

At the end of the dispensing, the user operates the lever 9 ' one more revolution, which prints the end character and releases the ticket.

The cycle is over and can start again.

According to the invention, the locking device 16 selects the delivery paths 12 or 14, but in any case leaves the handle 19 the possibility of actuation between one Closed position and an open position.

This can be achieved with a three-way cock as shown in FIGS.

According to these figures, the three-way valve has a body 1o ^l which contains a rotatable, socket-like switching element 2o which, depending on its angular position, opens into the outlet, the outlet connected to the line 12 or the outlet (not shown) connected to the hose 14 . The locking takes place by means of a finger 16 'which interacts with a stop 21. The stop 21 is attached to a shaft 22, which in turn is non-rotatably connected to the switching element 2o.

The lock does not block the switching element 2o completely, but limits its rotatability only between the Stop 21 and one of stops 23, 24, so that it is not possible to switch from one type of charge to the other. To The free path of the handle 19 enables both sides of the finger 21 to pass from an open position to a closed position and to control the start and end of the delivery accordingly.

The finger 16 ″ is controlled by the zero reset device 9 by means of a flexible cable, for example a Bowden cable 25, which in turn is actuated by levers 26 and 27 which are driven by an axis 28 ^{cooperating with the lever 9 f.}

This control could also take place in other ways, for example electrically, electromagnetically or hydraulically.

By using a switching element 2o as a 90 ° elbow to operate the three-way valve 1o, which is ^{rotatable about the axis of one of the} outputs, there can never be a connection between the outputs 11 and 13.

A total printer can be used, i.e. a printer with which the quantities dispensed at the beginning and can be printed out at the end of the operation, the dispensed volume being the difference between the two quantities results; a zero-reset printer can also be used, in which the first character printed is always a line of zeros and the second character corresponds to the volume dispensed.

The adding printer enables a more precise control of the dispensed quantities.

Instead of the flexible line and flexible hose, 1o two flexible hoses, one with a smaller passage, the other with a larger passage.

The invention is particularly well suited for tanker trucks for dispensing fuel, but can also be used for dispensing devices connected to stationary containers can be used.
