摘要： A check valve assembly comprising a main housing having a main fluid passage extending along a main flow axis between a first port connectable to a first pipe and a second port connectable to second pipe; a shut off element disposed at least in part within the main housing, said shut off element extending along a shut off element axis, and a check valve. The shut off element is displaceable between a working position in which the shut off element allows a fluid flow between the first port and the second port and through the check valve, and a service position blocking the fluid flow through the shut off element. A check valve receiving element is disposed at least in part within the main housing for removably accommodating the check valve in the check valve receiving element.

摘要： Improved valve seal and integrity systems and methods are disclosed. Pressure in an internal cavity of a valve may be monitored and stored to assist in determining whether one or more seals in the valve are leaking. Internal cavity temperature may also be recorded and monitored to assist in determining whether there are any valve seal leaks. Expected pressure corresponding to a detected internal cavity pressure (that may be determined by correlating temperature and known fluid properties) may be compared to detected internal cavity pressure to assist in determining the existence of valve leaks. Internal cavity pressures and pressure differentials over time may be used to determine remaining valve seal life, leak severity, and/or integrity of a check valve on the valve. Indications of seal life, leak severity, seal integrity, and/or check valve integrity may be displayed to an end user or otherwise provided to a database or computer.

摘要： A valve includes a housing having a housing cavity and at least two housing openings. A valve body is rotatably provided in the housing cavity and includes a valve body top portion, a valve body bottom portion and a valve body sidewall. The valve body sidewall has an upper valve body sidewall and a lower valve body sidewall which are connected to each other. An outer surface of the upper valve body sidewall is a partial cylindrical surface, and an outer surface of the lower valve body sidewall is shaped to have a gradually decreasing diameter in a direction from top to bottom. A seal is provided on the valve body sidewall and the seal is configured to match with the housing to enable the valve body sidewall to close at least one of the housing openings.

摘要： A valve stem for use in a fluid flow control valve having a valve body configured to receive a portion of the valve stem and to enable the valve stem to selectively rotate within the valve body between a fully-open position, where fluid is permitted to flow through the fluid flow control valve, and a fully-closed position, where fluid is prevented from flowing through the fluid flow control valve. The valve stem includes an elongate valve stem arm having a first end and a second end and a valve stem head integrally formed with and fixedly attached to the second end of the valve stem arm. The valve stem head includes a fluid inlet formed in the valve stem head, and a fluid outlet formed in the valve stem head, and a fluid passage that directs fluid from the fluid inlet, through the valve stem, and out of the fluid outlet.

摘要： A throttle valve is provided. The throttle valve includes a throttle valve body, a valve plug, a hollow seal and a first scraper. A flow path is formed in the throttle valve body. The valve plug is disposed in the throttle valve body. A notch is formed on the valve plug. By rotating the valve plug, the position of the notch is changed, and the degree of opening of the flow path is modified. The hollow seal is disposed in the throttle valve body. An abutting portion is formed on the hollow seal, and the abutting portion sealably abuts the valve plug. The first scraper is disposed on the valve plug. When the valve plug is rotated, the first scraper abuts the abutting portion to clean the abutting portion.

摘要： A distribution valve with an integrated flowmeter unit, which exhibits a main flow channel, through which a medium can flow in a main flow direction, and a secondary flow channel branching from the latter. The distribution valve includes a distribution valve housing containing a main pipe, a first conduit pipe connection, a second conduit pipe connection and at least one branch lying in between. The main flow channel in the main pipe runs from the first conduit pipe connection to the second conduit pipe connection. The branch empties into a first housing part, which includes an outlet. The outlet of the first housing part empties into a second housing part, which accommodates a flowmeter body and includes an outlet that forms a third conduit pipe connection. The secondary flow channel runs from the at least one branch of the main pipe to the outlet of the second housing part.

摘要： An isolation valve includes a dead chamber, including a body with a fluid-passing conduit, a device for obturating the fluid passage in the conduit, which may be actuated between a fluid-passing position and a position for obturating the fluid passage in the conduit. In its obturation position, the obturation device forms a dead chamber. A wall of the obturation device comprises a through-hole, in which is positioned a device for decompression of the dead chamber. A hydrocarbon transport facility includes at least two pipes connected through such an isolation valve with a dead chamber.
