In order to ensure the normal operation of the steam turbine and quickly cut off the power source in an emergency to prevent the accident from expanding, the mechanical trip isolation valve F3DG5S2-062A-220DC50-DFZK-V/B08 came into being. We will explore the isolation function of this type of isolation valve in depth, and conduct a comprehensive analysis from the design principle, working mechanism, application scenario to advantages and characteristics, hoping to help you understand this valve.

1. Overview of mechanical trip isolation valve

As a key component in the steam turbine control system, the mechanical trip isolation valve F3DG5S2-062A-220DC50-DFZK-V/B08 is responsible for protecting the steam turbine from damage, ensuring personnel safety, and maintaining the stable operation of the system. The valve combines advanced manufacturing technology and sophisticated design concepts to ensure reliable isolation and shut-off functions under various working conditions.

The valve core and valve seat of the mechanical trip isolation valve F3DG5S2-062A-220DC50-DFZK-V/B08 are made of high-quality materials, such as stainless steel or alloy steel, to ensure that they can maintain good sealing performance under high pressure, high temperature and corrosive media environment. At the same time, the structural design of the valve fully considers the dynamic characteristics of the fluid to reduce the impact and wear of the fluid on the valve core and extend the service life of the valve.

2. Working mechanism of the isolation function

When the turbine needs to be shut down for maintenance, testing or encounter an emergency, the emergency trip device will trigger the connecting rod mechanism to quickly close the mechanical shut-off isolation valve. This mechanism ensures that even if the operator cannot arrive at the site in time, the valve can automatically close, cut off the high-pressure safety oil system, and prevent the accident from expanding.

3. Application scenarios of isolation function

The isolation function of the valve F3DG5S2-062A-220DC50-DFZK-V/B08 plays an important role in a variety of application scenarios:

1. Steam turbine maintenance: When the steam turbine needs to be shut down for maintenance, the high-pressure safety oil system can be cut off by closing the mechanical trip isolation valve to ensure that maintenance personnel can work in a safe environment.

2. Flying ring oil injection test: When performing the flying ring oil injection test, it is necessary to temporarily block the oil discharge port of the high-pressure safety oil to prevent the entire steam turbine unit from tripping. At this time, the isolation function of the mechanical shut-off isolation valve is particularly important. By closing the valve, the smooth progress of the test can be ensured while ensuring the safety of the unit.

3. Emergency shutdown: When the steam turbine has a serious fault or requires emergency shutdown, the mechanical trip isolation valve can quickly cut off the high-pressure safety oil system to prevent the steam turbine from continuing to operate, thereby avoiding possible faults or accidents.

4. Features of isolation function

The isolation function of the mechanical trip isolation valve F3DG5S2-062A-220DC50-DFZK-V/B08 has the following advantages and characteristics:

1. High sealing performance: The gap between the valve core and the valve seat is extremely small, which can ensure good sealing performance under high pressure, high temperature and corrosive media environment.

2. Quick response: Whether it is manual or electric operation, the mechanical trip isolation valve can open or close the valve in a short time, ensuring that the high-pressure safety oil system can be quickly cut off in an emergency.

3. Safe and reliable: The valve has a reasonable structural design and can withstand the impact and corrosion of high pressure, high temperature and corrosive media, ensuring that it can maintain stable performance during long-term use. At the same time, the emergency trip device trigger mechanism ensures that the valve can be automatically closed even if the operator cannot arrive at the scene in time to prevent the accident from expanding.

4. Easy maintenance: The mechanical shut-off isolation valve has a reasonable structural design and is easy to repair and maintain. When repairs or replacement of parts are required, the valve can be easily disassembled and installed, reducing maintenance costs and time.

In summary, the isolation function of the mechanical trip valve F3DG5S2-062A-220DC50-DFZK-V/B08 is one of its key features. Through its unique design principle and working mechanism, it ensures the safety of the turbine during maintenance, testing or emergency situations.
