    摘要： An actuated rotary valves for reciprocating compressors used in oil and gas industry, the valve including a stator with a stator opening, a rotor with a rotor opening, and an actuation mechanism. The actuation mechanism is configured to receive a rotation motion and to actuate the rotor to perform first an axial translation moving away from the stator and then a rotation. The actuation mechanism includes an outer shaft configured to receive the rotation motion, and an inner shaft inside the outer shaft and configured to rotate the rotor. The outer shaft is configured to rotate a predetermined angular displacement while pushing the rotor away from the stator before engaging the inner shaft to rotate together with the rotor.

    摘要： Reciprocating compressors for the oil and gas industry with a timing valve and related methods are provided. A reciprocating compressor 100 has a chamber 110, a timing valve 150, an actuator 160 and a controller 170. A fluid entering the chamber 110 via a suction valve 130 is compressed inside the chamber, and evacuated from the chamber via a discharge valve 140. The timing valve is located between the chamber and a fluid volume at a relief pressure that is lower than a pressure in the chamber when the timing valve is opened. The actuator is configured to actuate the timing valve. The controller is configured to control the actuator such that to open the timing valve during an expansion phase of the compression cycle, and to close the timing valve when the relief pressure becomes equal to the pressure in the chamber or when the suction valve is opened.

    摘要： Apparatuses and methods overcoming the technical challenges in actuating valves of reciprocating compressors used in oil and gas industry are provided. A valve assembly includes an actuator, a shaft, a collar and a thrust bushing. The actuator is configured to generate a displacement. The shaft configured to receive a rotating motion caused by the displacement and to penetrate inside a compressor body of the reciprocating compressor. The collar is located close to a location where the shaft penetrates inside the compressor body. The thrust bushing is located between the collar and the compressor body. The rotating motion actuates a valve closing member of a valve inside the compressor body.

    摘要： The automatic valve comprises a valve seat (52) with first gas flow passages (58) extending there through, and a valve guard (54) having second gas flow passages (66) extending there through. Sealing rings (60) are arranged between the valve guard and the valve seat. A removable seat plate (68) is removably connected to the valve seat (52) and is provided with apertures (70) matching with the first gas flow passages (58) of the valve seat. The sealing rings are resiliently biased by resilient members (62) against the removable seat plate (68) to close the valve. The seat plate and the rings are made of non-metallic material.
