Technical Field

The utility model relates to an tanker aircraft calibrating installation's improvement specifically is a high accuracy tanker aircraft calibrating installation.

Background

With the rapid development of highway traffic in China, the gasoline stations are located along the highway, so that the inspection of the gasoline dispensers becomes a heavy task for quality and technical supervision departments. In order to ensure that the fuel dispensers of the gas station are metered accurately, each fuel dispenser needs to be detected by a national metrological verification organization regularly, and the gas station needs to perform self-calibration on each fuel dispenser regularly. The detection and the self-correction are both carried out by adopting a comparison method of a standard measuring device, namely, oil to be oiled is thrown into the standard measuring device, and the oil quantity indicating value of the oiling machine is compared with the liquid level indicating value of the standard measuring device to check the accurate condition of the oiling machine so as to determine whether the oiling machine is qualified or whether the oiling machine needs to be adjusted and repaired.

The metering container of the oiling machine calibrating device is a key part of the whole calibrating device, the existing common single-layer container has the advantages of simple structure and easiness in processing, but the temperature of the oil material detected in the calibrating environment is different due to the temperature of the calibrating device container in the calibrating process, particularly under the condition that the temperature difference between the medium temperature and the environment temperature is large in summer and winter, the actual temperature of the container is changed in the process of filling the container with the oil material, and the volume of the container can be changed due to expansion caused by heat and contraction caused by cold, so that metering inaccuracy is caused, and the calibrating work is directly influenced.

Although a double-layer heat-insulating container structure is designed for solving the problem, the volume of the container needs to be calibrated periodically every year due to the limitation of the processing technology in the prior art and natural conditions such as expansion with heat and contraction with cold, the higher-level department usually adopts a container with higher precision to calibrate so as to judge whether the volume of the oiling machine calibration mechanism is standard or not, and the oiling machine calibration mechanism is rejected and returned to a factory once the volume deviation of the oiling machine calibration mechanism is large and does not meet the use standard.

In summary, it can be seen that how to implement the calibration of the oiling machine every time the oiling machine is calibrated by the calibration device at present is a standard volume, which is a technical problem to be solved.

SUMMERY OF THE UTILITY MODEL

To the problem mentioned in the background art, the utility model provides a high accuracy tanker aircraft calibrating installation can realize that the container volume can finely tune to overcome the problem of the standard container volume change that causes such as manufacturing process defect, expend with heat and contract with cold.

The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a high accuracy tanker aircraft calibrating installation, includes vessel shell, notes oil pipe and measurement neck all communicate with vessel shell, still be equipped with level sensor in the measurement neck, level sensor passes the measurement neck and probes into in the vessel shell, still be equipped with temperature sensor in the vessel shell, still include adjustable plunger, adjustable plunger pass vessel shell and with vessel shell spiro union.

Preferably, the adjustable plunger penetrates through the container shell and is in threaded connection with the container shell, specifically, a fixed pipe is further arranged on the outer wall of the container shell, and the adjustable plunger is in threaded connection with the fixed pipe.

Preferably, a sealing ring is further arranged on the adjustable plunger, and the sealing ring is located between the adjustable plunger and the fixed pipe.

To sum up, the utility model discloses following beneficial effect has: the utility model discloses a high accuracy tanker aircraft calibrating installation can be through the design of plunger with adjustable, has realized that the volume size in the container casing can finely tune to no matter be production technology problem or expend with heat and contract with cold problem or product collision deformation scheduling problem again cause standard volumetric change, the plunger with adjustable all the accessible carries out the spiro union and rotates, and then causes the change of the volume size in the container casing, makes the cavity internal volume reach standard test volume.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

A high-precision oiling machine calibrating device comprises a container shell 1, an oil filling pipe 2 and a metering neck 3, wherein the oil filling pipe 2 and the metering neck 3 are both communicated with the container shell 1, a liquid level sensor 4 is further arranged in the metering neck 3, the liquid level sensor 4 penetrates through the metering neck 3 and extends into the container shell 1, a temperature sensor 5 and an adjustable plunger 6 are further arranged in the container shell 1, and the adjustable plunger 6 penetrates through the container shell 1 and is in threaded connection with the container shell 1; the adjustable plunger 6 penetrates through the container shell 1 and is in threaded connection with the container shell 1, specifically, a fixed pipe 7 is further arranged on the outer wall of the container shell 1, and the adjustable plunger 6 is in threaded connection with the fixed pipe 7; the adjustable plunger 6 is further provided with a sealing ring 8, and the sealing ring 8 is located between the adjustable plunger 6 and the fixed pipe 7.

In specific implementation, firstly, the volume of the vessel shell 1 is calibrated, if the vessel shell has a standard volume of 10L, when the detection is performed, firstly, the standard 10L of gasoline is adopted to perform oil injection operation on the interior of the vessel shell 1, the oil enters the vessel shell 1 through the oil injection pipe 2, after the 10L of gasoline with the standard volume is injected into the vessel shell 1, whether the scales of the metering neck 3 and the reading of the liquid level sensor 4 are 10L or not is observed, if the deviation occurs, the adjustable plunger 6 is rotated on the vessel shell 1 through a threaded port, if the reading does not reach 10L, the inner volume is larger, the adjustable plunger 6 is further screwed into the vessel shell 1, the reading reaches 10L, if the reading exceeds 10L, the inner volume is smaller, the adjustable plunger 6 is further screwed out of the vessel shell 1, so that the reading reaches 10L, and the stroke of the thread is increased through the fixed pipe 7 arranged on the container shell 1, the oil leakage risk is further reduced, and meanwhile, the sealing ring 8 on the adjustable plunger 6 can further ensure the sealing property between the adjustable plunger 6 and the fixed pipe 7.
