What is the steering valve of the excavator?
In the field of construction machinery, the excavator steering valve is a key component, especially playing an important role in the excavator's hydraulic system. This article will introduce in detail the definition, function, structure, common faults and solutions of the excavator steering valve, and attach hot topics and hot content in the past 10 days to help readers fully understand this component.
1. Definition and function of excavator steering valve
The excavator steering valve is the core control component in the excavator hydraulic system. It is mainly used to control the flow direction and flow rate of hydraulic oil to realize the steering action of the excavator. Its main functions include:
| Function | Description |
|---|---|
| Control the flow of hydraulic oil | Through the movement of the valve core, the flow direction of the hydraulic oil is changed to achieve steering. |
| Adjust hydraulic oil flow | By opening and closing the valve port, the flow of hydraulic oil is adjusted and the steering speed is controlled. |
| Ensure system stability | Ensure the stable operation of the hydraulic system in high-pressure environments. |
2. Structure of excavator steering valve
The excavator steering valve usually consists of the following parts:
| parts | function |
|---|---|
| valve body | Carrying other components and providing hydraulic oil passages. |
| valve core | Control the flow direction and flow rate of hydraulic oil through movement. |
| spring | Provides a restoring force to ensure that the valve core returns to its original position. |
| Seals | Prevent hydraulic oil leakage and ensure system sealing. |
3. Common faults and solutions of excavator steering valves
The excavator steering valve may have some failures during use. The following are common problems and solutions:
| Fault phenomenon | Possible reasons | Solution |
|---|---|---|
| Insensitive steering | Valve core stuck or hydraulic oil contamination | Clean the valve core or replace the hydraulic oil |
| Hydraulic oil leak | Seals are aged or damaged | Replace seals |
| Weak steering | Insufficient hydraulic pressure | Check hydraulic pump and pressure regulating valve |
