DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0015] Embodiment 1

[0016] As Figure 1 , 2 shown, a specific embodiment of a flushing door hydraulic station according to the present utility model includes: an oil tank 1 and a flushing door oil cylinder. The oil tank 1 is filled with hydraulic oil. A gear pump 6 is installed on the oil tank 1. The motor 5 is connected to the gear pump 6 through a coupling 7 and is used to drive the gear pump 6. The oil outlet end of the gear pump 6 is connected to a main valve block 12. The main valve block 12 is connected to a four-way valve block 13. The four-way valve block 13 is connected to four flushing door oil cylinders. The main valve block 12 includes a plug-in check valve 8 arranged on the oil outlet path. The four-way valve block 13 includes a three-position four-way electromagnetic directional control valve 14 and a throttle valve 15 connected in series.

[0017] A plug-in overflow valve 9 is also installed on the main valve block 12, in parallel with the plug-in check valve 8 to protect the system from excessive pressure; a pressure gauge 10 and a pressure sensor 11 are also installed on the main valve block 12 to monitor and adjust the system pressure in real time.

[0018] A liquid level gauge 2, an air filter 3, and a liquid level temperature sensor 4 are installed on the fuel tank 1. The liquid level gauge 2 is used to monitor the oil inventory; the air filter 3 is used to filter the air impurities entering the fuel tank 1; the liquid level temperature sensor 4 is used to monitor the oil temperature to ensure the safe operation of the system.

[0019] The working principle of the present utility model: After the motor 5 is started, it drives the gear pump 6 to rotate through the coupling 7. The gear pump 6 sucks and pressurizes the hydraulic oil in the fuel tank 1. After the high-pressure oil is output from the gear pump 6, it first enters the main valve block 12. The check valve 8 in the main valve block 12 ensures that the oil can only flow in one direction and prevents backflow. Then the oil enters the four-way valve block 13. The four-way valve block 13 contains four independent three-position four-way electromagnetic directional control valves 14 and throttle valves 15. Each electromagnetic directional control valve 14 controls the action direction (open or closed) of a flushing door cylinder, and the throttle valve 15 is used to adjust the speed of the cylinder action. When the electromagnetic directional control valve 14 is energized, its corresponding oil circuit is connected, and the high-pressure oil enters the flushing door cylinder. The cylinder generates a linear motion under the action of the oil pressure, thereby driving the flushing door to open or close. After the action is completed, the oil in the cylinder flows back to the fuel tank 1 through the return oil circuit, forming a closed-loop oil circuit system.

[0020] The components in this article are all common standard components or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or obtained through conventional experimental methods. Therefore, no further description will be given here.

[0021] Although the specific embodiments of the present utility model have been described in detail above, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present utility model, and modifications or variations without creative labor are still within the protection scope of the present utility model.
