Problems solved by technology

Furthermore, in the equipment of the automotive industry, there is no question about explosion, which is actually a desired phenomenon, and the high pressure caused by explosion is easily dissipated in the environment
[0011] Furthermore, actuating valves in marine equipment (most commonly done with pneumatic or hydraulic actuators) requires large forces and may require large displacements compared to equipment in the oil and gas industry, although actuation time is not critical

Abstract

Apparatuses and methods overcoming the technical challenges in actuating valves of reciprocating compressors used in oil and gas industry are provided. A valve assembly (400) includes (1) an actuator (410) configured to provide a displacement, (2) a shaft (430) configured to transmit the displacement from the actuator to a valve closing member of a valve of the reciprocating compressor, and (3) a displacement transmission mechanism connected to the shaft, and configured to amplify the displacement and / or a force associated with the displacement provided by the actuator to actuate the valve closing member of the valve.

Description

technical field [0001] Embodiments of the subject matter disclosed herein relate generally to apparatus and methods for actuating valves used in reciprocating compressors in the oil and gas industry, and more particularly to amplifying displacement between an actuator and an actuated valve and / or force associated with displacement. Background technique [0002] A compressor is a mechanical device that increases the pressure of a gas and can be found in engines, turbines, power generation, cryogenic applications, oil and gas processing, and more. Due to its widespread use, various mechanisms and technologies related to compressors are generally researched to improve compressor efficiency and solve problems related to specific operating environments. One characteristic that must be considered in compressors used in the oil and gas industry is that compressed fluids are often corrosive and flammable. The American Petroleum Institute (API), the organization that develops recog...
