This is a new sealing device for oil loading on top, On the premise of no changing the tank mouth, the sealing problem of crane pipe with oil and gas recovery is solved.Can realize one-step operation (one step can be locked, one step can be released);Equipped with a protective level alarm probe (proprietary built-in, anti-impact);The cylinder is specially made with proprietary technology.The rubber pad is specially made.Can be against benzene, xylene resistance, gasoline resistance, corrosion resistance, anti-static;It has 6 patents and 2 proprietary technologies.
After testing, the leakage detection value of domestic sealed crane pipe when loading is low limit of 3.5-67% V (hydrocarbon, gasoline explosion range of 1.4-7.6% V).
For the locking seal device of manual automobile, the lowest leakage detection value of crane pipe is 0.0%V (hydrocarbon), and the average value is 0.05%V (hydrocarbon).
The leakage detection value of the third party pneumatic locking sealing device for
tank truck loading is 0.006%V (60ppm) , which is far lower than the 0.05%V leakage value stipulated by the state.
The lowest leakage detection value of the third party of pneumatic locking sealing device for train loading is 0.008%V (80ppm), also which is far lower than the national leakage value of 0.05%V, and which is more than one percent of similar sealing devices (23 times higher than that of similar devices -- 452 times higher).  |

◆ Good sealing performance
The clamping force provided by the locking mechanism overcomes the factors that cause seal failure.The pressure force of the mechanism only ACTS between the sealing device and the tank car mouth, and has little influence on external factors such as crane pipe and tank car. Even in the above adverse conditions, it can also produce a reliable seal.
◆Long service life
The design of the sealing device is reasonable, the structure is compact, there is no other wearing parts except the sealing gasket, the whole design service life of the device can reach 20 years.
◆Wide range of application
In addition to the special seal device for the tank mouth, the car crane tube lock type seal device is applicable to most of the tank mouth, the train crane tube lock type seal device is applicable to all kinds of train tank mouth.High elastic rubber pad is made according to different conveying medium with different formula.
◆High degree of automation
According to the field situation, the pneumatic method is selected to realize the automatic control of the locking action. For the automatic crane pipe, the crane pipe and the sealing device can be fully controlled.

The cylinder drives the locking mechanism upward movement, making the rubber sealing ring and the locking mechanism move relatively, to clamp the tank mouth, to achieve the sealing device and tank mouth of the tank into a whole effect, so as to realize the real sense of airtight loading.
Characteristics
◆Simple operation, through the air control valve one step can be locked or released, greatly reduce the labor intensity of operators.
◆Double material compression cylinder is the driving mechanism, the middle flow, the outer layer through oil and gas, interlayer through compressed air, unique and compact structure.
◆Realize oil, oil and gas, compressed air bidirectional separation of material, improve the proportion of oil and gas collection.
◆The double-pass compression cylinder can provide 400kgf clamping force for the locking mechanism, and the seal is safe and reliable.
◆The safety and service life of the equipment are greatly improved by the application of high strength explosion-proof materials and safety gas path control system.
◆Rubber seal ring is specially made compound rubber, filled with plant fiber, graphite and other anti-static materials, the formula is unique.

The cylinder drives the locking mechanism to move upward so that the sealing rubber ring moves relative to the locking mechanism to clamp the tank mouth so as to realize the sealing of the tank mouth.Adopt two kinds of rubber ring structure, can be respectively on the size of the tank car mouth sealed.
Characteristics
◆Only need to turn the pneumatic rotary valve switch 90 degrees, can complete the operation, which make the labor intensity is very low.
◆The sealing device is made of aluminum bronze and aluminum alloy, which ensure sealing device much more safe, explosion-proof, reliable and has a long service life.
◆Rubber pad will be adopted different unique formula according to the different medium with corrosion resistance, aging resistance.
◆Almost No-leakage loading .Oil and gas enter the recovery system in time, which greatly reduces the concentration of oil and gas on site and reduces the peculiar smell on site.
◆The anti-overflow probe is installed in the installation groove on the sealed cylinder body to prevent the probe from being damaged by collision or knock.
◆It has the function of closing off the gas phase pipe. When loading and sending oil, the sealing device is locked, the continuous valve is opened, and the oil and gas enters the recovery pipe.After loading, locking device resetting and the connecting valve is closed.

A special cylinder drive locking mechanism is used to lock the inside of the tank mouth, so that the rubber seal pad on the cover plate is close to the tank mouth, and the rubber pad is compressed and deformed to realize the full sealing of the sealing device and the tank mouth.Adopt two rubber ring structure, can respectively the size of the train can be effectively sealed the mouth.
Characteristics
◆The cylinder drive locking mechanism can provide 1000kgf compression force for the gasket.
◆Only need to turn the pneumatic rotary valve switch 90 degrees, can complete the operation, the labor intensity is very low.
◆The sealing device is made of stainless steel and aluminum alloy for long service life.
◆The centering device can automatically correct the deviation after it reaches the tank mouth, so as to achieve accurate alignment.
◆Double material compression cylinder is the driving mechanism, the middle flow, the outer layer through oil and gas, interlayer through compressed air, unique and compact structure.
◆The following mechanism is connected with the moving oil cylinder, which can compensate the alignment error between the crane tube and the tank mouth and the sinking of the vehicle. The seal is more reliable.
