As shown in fig. 1 and 2, the flow meter 104 is used for monitoring the flow rate of fluid during the loading and unloading process and controls the flow rate of the loading and unloading vehicle in conjunction with the control valve 105. The control valve 105 controls the flow of the fluid loading and unloading vehicle, improves the loading precision and prevents the water hammer phenomenon during the loading and unloading vehicle. The booster pump 106 is used to pressurize the truck fluid. When the manual valve 107 meets the control requirements of the process or is overhauled, the pipeline equipment is manually operated to open and close.
As shown in fig. 1 and 2, the filter 108 is used for filtering impurities in the pipeline 102 and the material, and protecting the booster pump 106 and the corresponding instrument valve. Pressure gauge 109 is used to monitor pressure parameters of the fluid during the loading and unloading process. The temperature gauge 110 is used to monitor temperature parameters of the fluid during the loading and unloading of the truck. The safety interlock 111 is used to provide protection against static electricity, oil spill, etc. during loading and unloading.
Consequently, adopt the integrative sled of loading and unloading, can enough satisfy the loading, can satisfy again the unloading, both can go on in step, only set up in a place the integrative sled can, saved and transported regional spatial position, reduce equipment cost's expenditure simultaneously.

When the fluid flows through the horizontal section of the elbow 202, the airflow and part of the fluid will enter the outer pipe 207 and the inner pipe 208 and then be discharged along the outer holes 205 and the inner holes 206, and because the aperture ratio of the outer pipe 207 and the inner pipe 208 is small, during the discharging process of the outer holes 205 and the inner holes 206, an acceleration is generated, which is also equivalent to generating a siphon principle, and generates suction force on the fluid at the horizontal section, so that the fluid is sucked to generate acceleration and rapidly pass through the elbow 202, and the fluid can be continuously and rapidly output.
Due to the special positions of the inner hole 206 and the outer hole 205, the inertia force generated by the fluid can be weakened when the airflow and the fluid pass through, and the fluid can be guided to hit the vertical section of the elbow 202, so that the loss at the position of the elbow 202 is reduced, the flow velocity of the fluid is improved, and the loading efficiency of the fluid is improved.
