Patent number: 10415711Abstract: The invention relates to a mechanical energized sealing ball valve comprising a seat, a ball assembly, and a single valve stem that operates both the sealing member and the ball. The ball comprises a ball and a sealing member. The valve stem drives the ball to rotate between open position and close position. When the ball reaches the close position, the sealing member, operated by the same valve stem, moves away from the ball to press and sit against the seat. The invention has the advantages that: the valve has a compact structure, the friction-free on/off is achieved, the mechanical energized sealing force is even and reliable, the ball is retracted and locked in the opening position to protect against turbulence-induced damage, low operating torque, the open/close operation is rapid, and the valve stem seal operates simply and reliably.Type: GrantFiled: January 16, 2018Date of Patent: September 17, 2019Assignee: Zibo Votaisi Petrochemical Equipment Co., LtdInventor: Xiaoqi Liu

Patent number: 10415712Abstract: An air admittance valve preventing mephitis overflow, having a main body with an air entry guide base defining an air entry guide; a pivot support; and a valve seat. A sealing valve group having a sealing valve body that defines a recess; a flexible member; a pivot housing; and a pivot. The valve seat is located about the air entry guide. The pivot is located in the pivot housing and the pivot support, and the pivot is located along, or adjacent to, the center of gravity of the sealing valve body. The flexible member is at least partially located in the recess and abuts the main body; and when the air admittance valve is closed, the sealing valve body abuts the valve seat.Type: GrantFiled: October 18, 2017Date of Patent: September 17, 2019Inventors: Chao Chi Chen, Michael Chiang

Patent number: 10415715Abstract: A subsea hydraulic system comprises a dual (or dual action) check valve on a port for connection to a remotely operated vehicle (ROV). The check valve provides backpressure to flow in either direction. This keeps hydraulic fluid in the hydraulic system, and seawater out. If flow needs to return to the ROV, it may flow out the port, subject to a selected back pressure.Type: GrantFiled: December 4, 2018Date of Patent: September 17, 2019Assignee: National Coupling Company, Inc.Inventors: Robert E. Smith, III, Timothy Goggans, Frank Harold Hollister
