Description

Technical Field

[0001] The utility model relates to the technical field of oil distribution equipment, in particular to a skid-mounted quantitative loading control station. Background Art

[0002] The utility model patent with publication number CN206417853U discloses a skid-mounted quantitative loading control station, including a base frame and a support frame fixed on the base frame, a quantitative loading system is installed on the support frame, the quantitative loading system includes an oil inlet end for connecting to a supply oil tank and a crane pipe for connecting to a tanker truck, a liquid phase delivery pipe is arranged between the oil inlet end and the crane pipe, and an oil delivery pump, a degassing filter, a check valve, a flow meter, an electro-hydraulic valve and a ball valve are arranged on the liquid phase delivery pipe in sequence from the oil inlet end to the crane pipe; the degassing filter includes a cylinder and an inlet arranged on one side of the cylinder, a filter cartridge is arranged inside the cylinder, the top of the filter cartridge is fixedly connected to an exhaust device and communicated with the exhaust device, and the inlet is arranged tangentially along the side wall of the cylinder; an opening cooperating with the exhaust device is arranged on the top of the cylinder, and the exhaust The device comprises an inner cylinder, the top of the inner cylinder passes through an opening and extends to the outside of the cylinder body, a sealing device is provided on the top of the inner cylinder, an exhaust port and an exhaust valve installed at the exhaust port are provided on the sealing device, and a floating ball matched with the exhaust valve is also provided in the inner cylinder; flow guide ports are evenly distributed on the side wall of the inner cylinder, and the horizontal plane where the flow guide ports are located is lower than the horizontal plane where the floating ball is located; an outlet is provided at the bottom of the cylinder body, and an outlet pipe is provided at the outlet, one end of the outlet pipe is connected to the bottom of the filter cylinder, and the other end passes through the outlet and extends to the outside of the cylinder, which solves the problem that the existing degassing filter changes the flow direction of the fluid when passing through the filter screen assembly through the partition, thereby allowing the gas in the fluid to escape, and this method completely relies on the gas itself to escape, which will cause the gas to escape in time and exhaust incompletely under the condition of a large flow rate. If there is any residual gas in the oil, it will enter the metering system with the oil, affecting the metering accuracy of the flow meter, causing the control system to misoperate the valve, thereby affecting the accuracy of quantitative loading.

[0003] From the drawings of its patent (attached Figure 3 ) It can be seen that the above patent has the following deficiencies:

[0004] 1) The pipeline design between the oil pump and the crane is unreasonable. Under the action of gravity, the liquid in the pipeline between the oil pump and the degassing filter will flow back, causing a vacuum to form in the pipeline between the oil pump and the degassing filter, resulting in inaccurate measurement;

[0005] 2) The vertical part of the end of the crane pipe near the liquid outlet is shorter. Therefore, when the oil pump stops working, the oil in the vertical part of the end of the crane pipe near the liquid outlet will flow out under the action of gravity, and the crane pipe cannot be filled with oil. As a result, the next time the truck is loaded, the measurement will be inaccurate because the crane pipe cannot be filled with oil. Utility Model Content

[0006] In view of the problems existing in the existing skid-mounted quantitative loading control station, the utility model is proposed.

[0007] Therefore, the purpose of the utility model is to provide a skid-mounted quantitative loading control station, which solves the problem that the pipeline design between the oil pump and the crane pipe in the above-mentioned patent is unreasonable. Under the action of gravity, the liquid in the pipeline between the oil pump and the air remover filter will flow back, thereby causing a vacuum to form in the pipeline between the oil pump and the air remover filter, resulting in inaccurate metering; the vertical part of the end of the crane pipe near the liquid outlet is shorter, so when the oil pump stops working, the oil in the vertical part of the end of the crane pipe near the liquid outlet will flow out under the action of gravity, and then the crane pipe cannot be filled with oil, so that the next time the vehicle is loaded, the measurement is inaccurate because the crane pipe cannot be filled with oil.

[0008] In order to solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0009] A skid-mounted quantitative loading control station comprises a base frame, a support frame is mounted on the base frame, an oil pump is mounted on the base frame, the oil pump is connected to a special-shaped pipe through a pipeline assembly, a fuel spray gun is mounted at the end of the special-shaped pipe, and the inner cavity volume of the special-shaped pipe is greater than the sum of the inner cavities of each pipe in the pipeline assembly.

[0015] Compared with existing technologies:

[0016] By arranging a special-shaped pipe at the end of the pipeline assembly as an oil outlet pipe, the amount of oil in the special-shaped pipe will be greater than the sum of the oil amounts in the pipeline assembly, thereby avoiding the oil backflow in the second pipeline connected to the oil pump, and ensuring that the oil in the second pipeline, the third pipeline, the fourth pipeline, the first pipeline and the Z-shaped pipe in the entire pipeline assembly does not flow back.
