Description

The claimed utility model relates to filling stations and is a fuel-dispensing installation for measuring the mass and volume of liquid motor fuel (ЖМТ) when dispensing vehicles into vehicles and can be used at filling stations or tank trucks. Fuel-dispensing installation allows for metered release of liquid metal coolants.

Known fuel dispensing column containing a filter, electric motor, pump, gas separator, float chamber, mass flow meter, flow change valve with electromagnetic control, pressure hose, indicator, transfer valve (patent for useful model RU 82454 U1, priority from 11/21/2008, IPC B67D 5/00). The disadvantage of this design is the dependence of the measurement error on the stability of the zero mass flow meter, complex maintenance and repair of the mass flow meter, made in a single design.

Known measuring installation consisting of a local control station, a grounding device, a check valve, a filter, an electric pump unit, a gas separator, a Coriolis mass flow meter, an electromagnetic valve and a thermal sensor (patent for a useful model RU 111284, priority from 06.17.2011, IPC - G01F 11/22).

The disadvantage of this measurement setup is complicated maintenance, repair of a mass flow meter, performed in a single design. Another disadvantage is the use of a check valve without additional installation of a safety valve, which during operation at high temperatures will lead to an increase in pressure inside the hydraulic system and, as a result, blocking the flow of fuel by the check valve.

Known measuring installation containing a local control station, a grounding device, a liquid temperature sensor, a check valve, a filter, an electric pump unit, a gas separator, a Coriolis-type mass flow meter, a moisture meter, a solenoid controlled valve, a display and control unit (utility model patent RU 128711 U1 , priority of 10.10.2012, IPC - G01F 11/22).

The disadvantage of this measurement setup is complicated maintenance, repair of a mass flow meter, performed in a single design. Another disadvantage is the use of a check valve without additional installation of a safety valve, which during operation at high temperatures will lead to an increase in pressure inside the hydraulic system and, as a result, blocking the flow of fuel by the check valve.

Of the known analogs, as the closest to the useful model is a measuring unit containing a liquid temperature sensor, a check valve, a filter, an electric pump unit, a gas separator, a Coriolis-type mass flow meter, a moisture meter, an electrically controlled hydraulic valve and a display and control unit (patent for a useful model RU 160835 U1, priority of 04/10/2016, IPC - G01F 11/22).

The disadvantage of this measurement setup is complicated maintenance, repair of a mass flow meter, performed in a single design. Another disadvantage is the use of a check valve without additional installation of a safety valve, which during operation at high temperatures will lead to an increase in pressure inside the hydraulic system and, as a result, blocking the flow of fuel by the check valve.

The task to be solved by the utility model is to create a fuel-dispensing installation with a simple constructive device of the hydraulic unit, high measurement accuracy of the dose given, operational reliability and stability during operation in a wide range of ambient temperatures.

The technical result of the claimed utility model is to improve maintainability and facilitate maintenance.

This technical result is provided by a combination of all essential features of the device due to the use of a separate execution in the utility model of a mass flow meter when the primary vibration converter (PPV) is located in the hydraulic compartment, and the electronic converter block (EBU) is located in the display and control unit.

The essence of the claimed fuel-dispensing installation is illustrated graphically, where:

figure 1 shows a fuel dispensing installation with suction-type hydraulics;

2 shows a fuel-dispensing installation with a pressure type hydraulics.

The proposed fuel-dispensing installation consists of a display and control unit (BIU) 9, a hydraulic compartment, a pressure hose 6, a flow indicator 7 and a dispensing valve 8, which are interconnected and connected to the input of a supply voltage line. The hydraulic compartment contains a filter 1, a check valve 2, a safety valve 3 with a pressure relief device, a primary vibration transducer (PPV) 4, a shut-off valve 5. Additionally, a pumping monoblock 10 and an electric motor 11 are used in the fuel-dispensing installation with suction-type hydraulics 11. In turn, The display and control unit contains electronic control units, displays, expansion modules, input devices and an electronic converter unit (ECU). Fuel-dispensing installation is characterized by the fact that it uses a mass flow meter of separate execution, that is, the primary vibration converter (PPV) 4 is located in the hydraulic compartment, and the electronic converter block (EBU) is located in the BIU 9.

The device fuel-dispensing installation is shown in detail in figure 1 and figure 2.

Fuel-dispensing installation is applied in stationary conditions at gas stations, fixed on the foundation, connected to tanks for fuel storage or installed on the chassis of the vehicle. The principle of operation of the fuel-dispensing installation is based on setting commands for issuing doses of mass or volume of liquid iron and liquid iron, obtaining information on the number of liquid iron gauge flowing through the measuring lines of the hydraulics compartment, and processing, recording, displaying measurement results and information.

The readings of the one-time meter on the display units are set to the zero position before each measurement of the mass or volume of the liquid iron gauge is performed automatically. Control of the fuel-dispensing installation is carried out remotely via the interface communication channel. For the issuance of fuel, you must set the dose from the control system. The installation starts the release of liquid metal fueling equipment to remove the dispensing crane 8. After this, the value and the mass or volume of fuel on the display panel are reset. During the vacation, the currently dispensed dose is displayed on the display. The end of the release occurs automatically upon completion of the issuance of a given dose. The fuel-dispensing installation beeps and the dispensed dose is displayed on the display.

The procedure for working with the fuel-dispensing installation during the release of liquid metal gauge: after setting the dose, you must remove the dispensing valve 8, lower the spout of the valve into the neck of the vehicle fuel tank, squeeze the lever and fix it. Next is the start of the fuel-dispensing installation. During the release of fuel on the indicators of the BIU displays information about the current dose. After the end of the release of fuel, it is necessary to press the lever of the dispensing crane 8 and put it in place.

The device and operation of the fuel-dispensing installation during the release of ZhMT

Under the influence of the discharge created by the pump monoblock 10 or the submersible pump in the tank of the gas station, the fuel from the tank through the filter 1 enters the FPV 4, the sensors of which produce signals depending on the amount of fuel passing through it, transmit them to the EBU, which calculates the mass or volume fuel dose, and transmits information to the control unit. Next, the fuel through the open valve shut-off 5, pressure hose 6, flow indicator 7, the dispensing valve 8 enters the vehicle tank. During the release of fuel on the scoreboard BIU 9 updated information about the current dose. As the preset dose is reached, a transition to a reduced flow occurs, and then a complete cessation of the supply of liquid metal filter.
