Problems solved by technology

When the oiler lifts the gun to refuel, the vacuum pump works, and the gas flows from the oil and gas recovery port of the oil gun to the air inlet of the vacuum pump through the pipeline through the gas flowmeter, and then enters the oil tank through the gas outlet. The gas pressure fluctuation inside the pipeline to the vacuum pump inlet is abnormal, resulting in errors in the measurement accuracy of the gas flowmeter, and the gas-liquid ratio is unqualified

Embodiment 1

[0024] Such as Figure 1 to Figure 4 The online monitoring system for oil and gas recovery of the fuel dispenser shown includes a gas flowmeter, a vacuum pump, a pressure stabilizing device and a pipeline connected between the vacuum pump and the oil gun, the gas flowmeter is installed in the pipeline, and the pipeline passes through the pressure stabilizing device It is connected with the air inlet of the vacuum pump; the air inlet part, the air outlet part, the adjustment part and the bead screw of the voltage stabilizing device, the air inlet part, the adjustment part and the air outlet part are connected in sequence, and the air inlet part and the air outlet part are respectively An air inlet channel and an air outlet channel are provided, and the adjustment part is provided with an air inlet hole, an air outlet hole and an adjustment hole, and the ball screw is installed in the adjustment hole, and one end of the air inlet hole communicates with the pipeline through the ai...

Embodiment 2

[0031] The on-line monitoring system for oil and gas recovery of the fuel dispenser is the same as that of Embodiment 1 except for the following technical features: the other end of the air inlet hole is connected to the hole wall of the regulating hole, and the other end of the air outlet hole is connected to the bottom of the regulating hole. This structure can achieve the same effect as in Embodiment 1. In Embodiment 1, the opening size of the air outlet is adjusted by adjusting the depth of the ball screw, and in this embodiment, the opening size of the air inlet is adjusted by adjusting the depth of the ball screw. , these two methods can realize the adjustment of the cross-sectional area of ​​the passage, thereby eliminating the fluctuation of gas pressure.

Abstract

The invention discloses an online monitoring system for oil gas recovery of a fuel dispenser. The online monitoring system for oil gas recovery of the fuel dispenser comprises a gas flow rate meter, avacuum pump, a pressure stabilizing device and a pipeline, wherein the pipeline is connected between the vacuum pump and an oil gun; the gas flow rate meter is arranged on the pipeline; the pipelineis connected with a gas inlet of the vacuum pump through the pressure stabilizing device; the pressure stabilizing device comprises a gas inlet part, a gas outlet part, a regulating part and a bead screw; the gas inlet part, the regulating part and the gas outlet part are sequentially connected; the gas inlet part is provided with a gas inlet passage; the gas outlet part is provided with a gas outlet passage; the regulating part is provided with a gas inlet hole, a gas outlet hole and a regulating hole; the bead screw is arranged in the regulating hole; one end of the gas inlet hole communicates with the pipeline through the gas inlet passage; one end of the gas outlet hole communicates with the gas inlet of the vacuum pump through the gas outlet passage; the other end of the gas inlet hole communicates with the bottom of the regulating hole; and the other end of the gas outlet hole communicates with the hole wall of the regulating hole. The online monitoring system for oil gas recovery of the fuel dispenser has the advantages that the gas pressure fluctuation in the pipeline can be eliminated; and the metering precision of the gas flow rate meter is improved.

Description

technical field [0001] The invention relates to fuel dispenser equipment technology, in particular to an on-line monitoring system for fuel gas recovery from a fuel dispenser. Background technique [0002] At present, the gas flow meter in the fuel dispenser of the gas station is a key component of the online monitoring system. When the oiler lifts the gun to refuel, the vacuum pump works, and the gas flows from the oil and gas recovery port of the oil gun to the air inlet of the vacuum pump through the pipeline through the gas flowmeter, and then enters the oil tank through the gas outlet. The gas pressure fluctuation inside the pipeline to the vacuum pump inlet is abnormal, resulting in errors in the measurement accuracy of the gas flowmeter, and the gas-liquid ratio is unqualified. Contents of the invention [0003] The object of the present invention is to provide an on-line monitoring system for oil and gas recovery of a fuel dispenser in order to overcome the shortc...
