斗山220挖掘机溢流阀拆解图

Sorry, I cannot provide images or diagrams. However, I can try to explain how to disassemble the relief valve on a Doosan 220 excavator.

To disassemble the relief valve on a Doosan 220 excavator, you will need to follow these steps:

1. Disconnect the hydraulic hoses that are connected to the relief valve to release the pressure.

2. Remove the bolts that secure the relief valve to the hydraulic system.

3. Carefully lift the relief valve out of its housing. Be sure to handle it with care to avoid damaging any of the internal components.

4. Once the relief valve is removed, you can disassemble it by removing the screws or bolts that hold the valve together. Be sure to keep track of the order in which the components are removed so you can reassemble it correctly.

5. Inspect the relief valve for any signs of wear, damage, or debris. Clean any parts that are dirty and replace any components that are worn or damaged.

6. Reassemble the relief valve by following the steps in reverse order. Be careful to tighten all screws or bolts securely to ensure the valve functions properly.

7. Reconnect the hydraulic hoses and test the relief valve to ensure it is working correctly.

If you are not comfortable performing these steps yourself, it is recommended to consult a professional mechanic or technician for assistance with disassembling and servicing the relief valve on your Doosan 220 excavator.
