6 FAQs about [Energy storage electric gate valve]
What is the world's first electric subsea gate valve actuator?
Rexroth Bosch Group presented the world’s first all-electric subsea gate valve actuator to replace conventional hydraulic cylinders without taking up any additional space. The actuator contained an electric drive, a motion control system, a safety device, and a pressure-compensated container.
What is all-electric subsea gate valve actuator?
The all-electric subsea gate valve actuator is the most critical component in the AE system, used to control the on–off, flow, and pressure control of production media such as oil, gas, and chemicals. It directly affects the operation of the AE system [ 11 ]. Several oil companies have carried out relevant research on this topic.
How does a subsea gate valve work?
During operation, the position-indicating rod moves in the override interface. When the position-indicating rod reaches the “O” position, the subsea gate valve is open; when the position indicating rod reaches the “S” position, the subsea gate valve is closed, as shown in Figure 9.
What are the different types of subsea gate valve actuators?
Subsea gate valve actuators can be classified into manual, hydraulic, and electric types, according to the driving method. The hydraulic subsea gate valve actuator driven by hydraulic power is the mainstream at present, and the all-electric control subsea gate valve actuator is the trend in applications.
What is a failsafe closing mechanism in a subsea gate valve actuator?
The failsafe closing mechanism in the all-electric subsea gate valve actuator exists to prevent safety accidents caused by system failures. In the various designs of the failsafe closing mechanism for the subsea gate valve actuator, the closing spring is the most reliable and widely used [ 37, 38 ].
What are the design requirements for a subsea gate valve?
According to ISO 13628 and API 17 standards, the design requirements include general requirements, basic requirements, and additional requirements. The prototype should be suitable for the opening and closing of the subsea gate valve, namely, the downward movement of the stem for opening the valve and the upward movement for closing the valve.
