Product Description

 

Product Description

The steam turbine unloading valve 0508.919T0104.06AW is a key component in the steam turbine control system, and its main function is to play a role in the operation of starting, stopping, and regulating load of the steam turbine. In emergency shutdown situations, the action of the unloading valve is crucial. It can quickly release the pressure oil in the lower chamber of the hydraulic motor piston, causing the valve to quickly close under the action of spring force, thereby ensuring the safe shutdown of the turbine.

Structure:
The structural feature of unloading valve 0508.919T0104.06AW is that it has multiple sealing surfaces, which makes it have extremely high requirements for machining accuracy and assembly. Due to its indeterminate structure, the interchangeability between unloading valves is poor. Each unloading valve needs to be compared with a specific hydraulic control block to ensure its normal operation. This not only increases the difficulty of maintenance and replacement, but also puts higher requirements on inventory management of components.

The O-ring seal between the internal pistons of unloading valve 0508.919T0104.06AW requires extremely high installation accuracy. Improper installation may lead to leakage and affect the normal operation of the steam turbine. Therefore, during installation and maintenance, it is necessary to strictly follow the prescribed requirements to ensure the safe and stable operation of the steam turbine.

Product Features:

1. Quick response: The unloading valve can quickly operate within milliseconds to meet the fast requirements of turbine start stop and load regulation.
2. High reliability: In case of emergency shutdown, the unloading valve must be able to operate reliably to ensure the safety of the turbine. Therefore, the design and manufacturing of unloading valves place great emphasis on reliability and durability.
3. High sealing performance: The sealing performance of the unloading valve is crucial for preventing oil leakage. The valve must be fully sealed in the closed state to prevent a decrease in oil pressure and external medium intrusion.
4. Compact structure: The design of the unloading valve needs to be as compact as possible to save space and reduce system complexity.
5. Long lifespan: The material and structural design of the unloading valve aim to achieve long-term stable operation, reduce faults and maintenance, and thus reduce the cost of the entire life cycle.

Applications:

1. Hydraulic system of construction machinery.

2. Lifting equipment and hydraulic machinery.

3. High pressure hydraulic system.

4. Hydraulic system in metallurgy, chemical industry, shipbuilding and other fields.

5. Hydraulic systems for equipment such as injection molding machines and die-casting machines.
