Problems solved by technology
Therefore, the corresponding gate valve actuators are also affected by different interfaces, performances and functions of gate valves, and there are many types. The corresponding test process of gate valve actuators is relatively complicated, and it is often necessary to repeatedly disassemble and assemble gate valve actuators and different gate valves to complete gate valve actuators. Various performance tests, and the large-diameter deep-water gate valve has a large volume, which is difficult to assemble and is limited by the conditions of the test site

Description
technical field [0001] The invention relates to the field of deep sea oil and gas field development equipment, in particular to an underwater gate valve load simulation device and an underwater gate valve actuator test method. Background technique [0002] With the rapid decline of onshore oil resources, offshore oil and gas development has become a hot spot for energy development in countries all over the world. As one of the basic components of underwater oil production facilities, the demand for underwater valves will continue to expand. The important driving device of the lower valve is installed on the seabed following the valve body. With the development and exploitation of oil and gas in my country's Bohai Sea and South China Sea and the world's exploration of deep-sea energy, the market demand for underwater valves and actuators is also increasing, and their technical requirements are also increasing. Therefore, carrying out research on the design, manufacture and r...
