[0013] like Figure 1 The utility model discloses a fluid automatic loading control system, comprising a storage tank 1 and a delivery branch pipe 4 connected in parallel to a delivery main pipe 2, a cut-off valve 5 and a flow meter connected to the delivery branch pipe 4, a delivery pump 3 installed on the connecting pipeline between the storage tank 1 and the delivery main pipe 2, a liquid level meter 7 arranged on one side of the delivery branch pipe 4, a remote control center controls the connection between the delivery pump 3 and the cut-off valve 5, and the flow meter signal is connected to the control center.

[0014] Three storage tanks 1 are connected in parallel on the delivery main pipe 2. A delivery pump 3 is installed on the output pipeline of each storage tank 1. The delivery pump 3 is turned on and off by a remote control center to provide sufficient fluid for the delivery main pipe 2 according to the capacity of the fluid in the storage tank 1. After the fluid is delivered to the delivery main pipe 2, the control center opens the shut-off valve 5 on the corresponding delivery branch pipe 4 according to the position of the delivery branch pipe 4 where the tank truck is located. After the shut-off valve 5 is opened, the fluid enters the tank truck through the loading crane pipe 6 for filling of the fluid.

[0015] Before fluid transportation, the staff sets the volume of the transported fluid through the control center. During the fluid transportation process, the flow meter detects the volume of the transported fluid. After the fluid volume reaches the set volume, the volume of the fluid added after the data conversion sent by the flow meter to the control center reaches the set volume. The control center sends a signal to the shut-off valve 5, and the shut-off valve 5 cuts off the delivery branch pipe 4; at the same time, the control center controls the delivery pump 3 to shut down.

[0016] When the delivery branch pipe 4 is loading the fluid, the level meter 7 detects the fluid level in the tank truck. When the level reaches a set height, the level meter 7 sends a signal to the control center to stop loading the fluid.

[0017] like Figure 1 As shown. The top of the delivery branch pipe 4 is connected to a purge device 8, and the bottom of the delivery branch pipe 4 is provided with a loading crane pipe 6. The tank truck is connected through the rigid loading crane pipe 6 to load the fluid. After the loading is complete, the delivery branch pipe 4 and the loading crane pipe 6 are purged and purged by the purge device 8 to clean the residual fluid inside.

[0018] like Figure 1 As shown, in order to ensure the safety of the loading process, a grounding wire 9 is connected to the delivery branch pipe 4. Not only the delivery branch pipe 4 is grounded, but also the platform supporting the tank truck is grounded.

[0019] As a preferred embodiment of the utility model, the main delivery pipe 2 is provided with an emergency cut-off device, and the emergency cut-off device is connected to the ground wire 9 , the liquid level meter 7 and the cut-off valve 5 by a signal.

[0020] The emergency shut-off device includes two forms: active and automatic. The emergency shut-off device is connected to the grounding wire 9, the liquid level meter 7 and the shut-off valve 5 signals through the control center. When it is detected that the grounding wire 9 is not grounded, the liquid level meter 7 is abnormal or the shut-off valve 5 is abnormal, the emergency shut-off device can be controlled by the control center to cut off the flow. Or after the emergency shut-off device receives the equipment abnormality signal from the control center, the emergency shut-off device does not receive the active shut-off signal from the control center, and the emergency shut-off device automatically cuts off the fluid in the delivery main pipe 2.

[0021] In addition, the loading status of the fluid can also be detected by the flow meter and the liquid level meter 7. If the increment of the liquid level meter 7 cannot match the fluid volume detected by the flow meter, it can be judged that there is leakage in the fluid loading. The control center notifies the staff and stops the fluid supply.
