Description
Technical Field
The utility model relates to a draw tank wagon technical field that unloads oil, concretely relates to ration system of unloading.
Background
(1) The oil unloading pump is matched with an oil unloading tank or an oil unloading pool (which are collectively called as a buffer container). After the tank truck enters the station, the oil is firstly unloaded into a buffer container, and then the crude oil in the buffer container is lifted into a subsequent system by a pump. The tank truck is fed and discharged through the underground weighbridge weighing, and the liquid discharging quality is calculated according to the difference.
(2) The oil is not discharged into the buffer container after the tank truck arrives, but the oil is directly connected with the pump through the unloading hose and the pipeline, and the crude oil in the tank truck is directly lifted into a subsequent system by the pump. 2 persons are required to cooperate to complete the unloading process, 1 person can pay attention to the liquid level change in the tank car at any time on the tank car, and the pump stopping information is sent to the other 1 person when the quick unloading is completed. If a plurality of tank trucks need to unload oil simultaneously, one oil unloading level is required to correspond to 1 pump. The tank truck is fed and discharged through the underground weighbridge weighing, and the liquid discharging quality is calculated according to the difference.
Disclosure of Invention
The utility model provides a quantitative unloading system for solve prior art's defect.
The utility model discloses a following technical scheme realizes:
a quantitative unloading system comprises a quick connector, a hose, a gate valve, an electric valve, a flowmeter and a check valve, wherein one side of the quick connector is connected with the hose, the other side of the quick connector is connected with the gate valve, the other end of the hose is connected with an oil unloading interface of a tank car, a pipeline between the gate valve and an inlet of an oil inlet and unloading lifting pump is sequentially connected with a one-way valve, the gate valve and a filter, and the pipeline is provided with a pressure gauge, a purge valve and a purge pipeline; the outlet of the oil inlet and outlet lifting pump is sequentially connected with a check valve, an electric valve, a flowmeter and a gate valve, and then enters a subsequent flow pipeline; the electric valve is connected with the accumulated flow value of the flowmeter and the oil feeding and discharging lifting pump in a linkage manner.
The flow meter measures an accumulated flow signal, and controls the electric valve to automatically interlock to stop the pump and close the electric valve.
The flowmeter returns to zero after the electric valve is automatically closed.
The multiple systems are connected in parallel, the systems are connected behind the quick connectors and the one-way valves, and gate valves are arranged.
The utility model discloses the advantage does: the buffer containers such as an oil unloading pool or an oil unloading tank can be saved, quantitative unloading can be realized, the pump is automatically stopped when the liquid unloading amount reaches the set amount, and the labor intensity of workers is greatly reduced.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Wherein: the device comprises a hose 1, a quick connector 2, a gate valve 3, a flowmeter 4, an electric valve 5, a check valve 6, a pressure gauge 7, a filter 8, a purge valve and a purge pipeline 9.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the drawings of the present invention will be combined below to clearly and completely describe the technical solutions of the present invention.
A quantitative unloading system comprises a quick connector 2, a hose 1, a gate valve 3, an electric valve 5, a flow meter 4 and a check valve 6, wherein one side of the quick connector 2 is connected with the hose 1, the other side of the quick connector 2 is connected with the gate valve 3, the other end of the hose 1 is connected with a tank car oil unloading interface, a pipeline between the gate valve 3 and an inlet of an oil inlet and unloading lifting pump is sequentially connected with a one-way valve, the gate valve 3 and a filter 8, and the pipeline is provided with a pressure gauge 7 and a purge valve and purge line 9; the outlet of the oil inlet and outlet lifting pump is sequentially connected with a check valve 6, an electric valve 5, a flowmeter 4 and a gate valve 3, and then enters a subsequent flow pipeline; the electric valve 5 is connected with the flow meter 4 to accumulate the flow value and the oil feeding and discharging lift pump in a linkage way.
The flow meter 4 measures the accumulated flow signal and controls the electric valve 5 to automatically interlock stopping the pump and close the electric valve 5.
The flow meter 4 is reset to zero after the electric valve 5 is automatically closed.
A plurality of systems are connected in parallel, the systems are connected behind the quick connectors 2 and the one-way valves, and gate valves 3 are arranged.
As shown in the attached figure 1, the oil-unloading tank truck is taken as an example. After an oil tank truck is pulled to enter a station, the oil tank truck enters an oil unloading level after being weighed by a weighbridge, a hose 1 with a quick connector is connected to an oil unloading interface of the oil tank truck, the other end of the hose 1 is connected with a fixed pipeline of an oil inlet and unloading lifting pump through the quick connector 2, crude oil enters a pump inlet pipeline from the tank through the hose, then enters the pump through a gate valve 3 and a filter 8, and after being pressurized by the pump, the crude oil enters a subsequent flow pipeline from an outlet of the pump through a check valve 6, an electric valve 5, a flowmeter 4 and the gate valve.
After the oil tank truck enters the oil unloading level, the hose 1 with the quick connector is manually connected to the oil unloading interface of the oil tank truck, and the accumulated flow value of the flow meter 4 is set according to the incoming weighing tonnage of the oil tank truck; starting the pump to discharge oil, and after the accumulated flow of the flow meter 4 reaches a set value, interlocking to stop the pump and automatically closing the electric valve 5 to stop discharging the oil, and enabling the flow meter to return to zero; the tank car leaves the unloading position to the underground weighbridge for weighing, and the oil unloading process is completed at one time.
