It can be understood that when the pressure in the first sealed cavity 31 rises, the gas in the first sealed cavity 31 enters the second sealed cavity 41 through the flexible flat pressing pipe 7; when the pressure rose in second seal chamber 41, the gas in the second seal chamber 41 got into first seal chamber 31 through flexible concora crush pipe 7 in, and the pressure in first seal chamber 31 and the pressure in the second seal chamber 41 remain the same throughout like this, and then, oil tank liquid level A also remains the unanimity throughout with the measurement liquid level C of liquid level detection pipe, the utility model discloses a concora crush function makes liquid level detection more accurate.
Specifically, the liquid level detection pipe 4 is a tubular structure with an open lower end and a closed upper end, and vertically extends into the liquid level a of the oil tank, the lower end is located below the liquid level a of the oil tank, the upper end is located above the liquid level a of the oil tank, and a second sealed cavity 41 is formed between the upper end and the liquid level a of the oil tank. During installation, the lower end of the liquid level detection pipe 4 extends into the position below the liquid level A of the oil tank, liquid enters the liquid level detection pipe 4 from the lower end of the liquid level detection pipe 4, air in the liquid level detection pipe 4 is compressed, and pressure rises.
Specifically, be equipped with first connecting tube spare 5 on sealing device 3, first connecting tube spare 5 and first sealed chamber 31 intercommunication are equipped with the second on the liquid level detection pipe 4 and connect pipe fitting 6, and pipe fitting 6 and the sealed chamber 41 intercommunication of second are connected to the second, and first connecting tube spare 5 and second are connected pipe fitting 6 and are passed through flexible concora crush pipe 7 intercommunication. The shape of the first connecting pipe 5 and the second connecting pipe 6 in this embodiment can be selected by those skilled in the art as required, and the purpose of sealing and convenient installation can be achieved, without limitation.
Preferably, the utility model discloses still include breather valve 8, breather valve 8 has first intercommunication mouth and second intercommunication mouth, and first intercommunication mouth is connected with first connecting tube 5, and the second intercommunication mouth is connected with flexible concora crush pipe 7. It is known from the hundred degree encyclopedia that a breather valve is a valve which ensures that the storage tank space is isolated from the atmosphere within a certain pressure range and is also open to the atmosphere (breathing) when the pressure exceeds or falls below this pressure range, and which serves to prevent the storage tank from being damaged by overpressure or vacuum and at the same time to reduce the evaporation loss of the stored liquid. The utility model discloses an increase breather valve 8, make the leakproofness of this device better, and further guarantee that the pressure in first sealed chamber 31 and the second sealed chamber 41 remains unanimous all the time to can not lead to sealing device 3 and liquid level detection pipe 4 to damage because of pressure is too big.
Specifically, the distance between the installation position of the second connecting pipe fitting 6 and the liquid level a of the oil tank is more than 500 mm. It should be noted that the liquid level of the oil tank is constantly changed in the operation process, but the highest point of the liquid level exists, and actually, when the second connecting pipe fitting 6 is installed, the installation position of the second connecting pipe fitting 6 should be located at about 500mm of the highest point of the liquid level, and the liquid level measurement at the position is verified to be accurate through tests.
Preferably, the length of the flexible flat pressure pipe 7 is 1.3 times the linear distance between the first connecting pipe member 5 and the second connecting pipe member 6. If the flexible pressure equalizing pipe 7 is too long, pressure difference exists in the first sealed cavity 31 and the second sealed cavity 41, and similarly, if the flexible pressure equalizing pipe 7 is too short, damping exists in the pipeline, pressure difference exists in the first sealed cavity 31 and the second sealed cavity 41, and finally the measured liquid level C is different from the liquid level A of the oil tank.
Specifically, the first connecting pipe 5 and the second connecting pipe 6 are both sealing pipes and are arranged oppositely.

The utility model discloses an airtight level measurement concora crush device can guarantee that the pressure of liquid level space and liquid level detection intraductal space remains unanimous throughout (first sealed chamber 31 is the same with the pressure in second sealed chamber 41 promptly), guarantees that liquid level detection is accurate to the device is in encapsulated situation all the time. Because the liquid level detection pipe is in a sealed positive pressure state consistent with the pressure in the oil tank sealing device and is completely sealed, the positive pressure state can slow down the volatilization rate of the medium, and the environment in the sealed and positive pressure state can reduce the volatilization loss of the liquid level detection pipe; the specific principle is as follows:
(1) as shown in fig. 1, the pressure in the upper space of the tank is P1, the pressure in the first seal chamber 31 is P2, and the pressure in the second seal chamber 41 is P3.
(2) As the storage medium is volatilized, the pressure P2 in the first sealed cavity 31 is increased, namely P2 is more than or equal to P1
(3) The pressure P3 in the second sealed cavity changes with the rise of the liquid level in the liquid level detection tube 4 and the change of the working conditions such as air temperature, and the pressure also changes, if the liquid level detection tube 4 is used to open the communication hole, then P3 is equal to or less than P1 and equal to or less than P2, and the liquid level difference exists between the liquid level in the second sealed cavity 41 and the liquid level in the first sealed cavity 31, that is, the liquid level difference exists between the measured liquid level C and the liquid level a in the tank.
(4) If the liquid level detection pipe 4 does not open a communication hole, the first sealing cavity 31 and the second sealing cavity 41 are communicated through the first connecting pipe 5, the second connecting pipe 6 and the flexible pressure equalizing pipe 7, under any working condition, P3 is equal to P2, the detection value of the liquid level detection pipe is always consistent with the liquid level in the oil tank, namely, the measured liquid level is equal to the liquid level of the liquid level A of the oil tank; meanwhile, it can be understood that if the liquid level detection pipe is not provided with a communication hole and a flexible pressure equalizing pipe is not provided to communicate the first seal cavity 31 with the second seal cavity 41, the pressure of P3 is increased, P1 is not more than P3, the measured liquid level C is greater than the liquid level A of the oil tank, that is, the measured liquid level is changed into the liquid level B without a pressure equalizing device, and the measurement is inaccurate.
The present invention has been further described with reference to specific embodiments, but it should be understood that the specific description herein should not be construed as limiting the spirit and scope of the present invention, and that various modifications to the above-described embodiments, which would occur to persons skilled in the art after reading this specification, are within the scope of the present invention.
