摘要： An air valve assembly (10) includes a main housing (12) including a coupling flange (14) for coupling to a pipe, and an air valve (20) fluidly coupled to the main housing (12). An actuator (28) is in fluid communication with the air valve (20) and a discharge tube (40). A non-contact liquid level sensor (30) is located in an external housing coupled to the main housing (12). The non-contact liquid level sensor (30) is in operative communication with the actuator (28).

摘要： A vacuum breaker valve includes a valve body and a vacuum breaking device mounted in the valve body. The valve body has a periphery provided with multiple air vent holes corresponding to the vacuum breaking device. The vacuum breaking device includes a mounting barrel, an elastic member, a braking member, a mounting plate, a water stop gasket, and a water inlet disk. The vacuum breaking device is assembled previously and then directly fitted into the valve body to construct the vacuum breaker valve. Thus, the vacuum breaking device and the valve body are combined together for a whole sale or the vacuum breaking device and the valve body are sold individually.

摘要： A method of dewatering a subsea pipeline bundle assembly before lifting the assembly from the seabed and an elongate carrier pipe comprising at least one internal fall that slopes downwardly towards a drainage outlet and at least one venturi formation that is aligned with the drainage outlet. The method comprises adding discrete buoyancy to the elongate carrier pipe that elevates the carrier pipe disposed between drainage outlets of the assembly. Each elevated portion defines inclined falls that slope downwardly in opposed longitudinal directions toward the respective outlets. Water within the carrier pipe drains down the falls toward the outlets. Injecting a dewatering fluid into the carrier pipe promotes expulsion of water from the pipe through the outlets by downward displacement of the water. Drainage may be assisted by a venturi effect driven by accelerating the flow of the dewatering fluid at a location in line with an outlet.

摘要： An actuator system is provided for operating a flow regulating element, e. g. a flap or a valve shutter for regulating a fluid flow in a fluid transportation pipe. The actuator system may include an actuator having an actuating motor coupled to a pivotable shaft of the flow regulating element which projects from the wall of the pipe. The actuator system has an attachment component for attachment of the attachment component to the wall of the fluid transportation pipe. The actuator and the attachment component are configured as a modular system.

摘要： A helical strake pole system that includes a tubular pole having a longitudinal axis and threaded attachment points. The system further includes a helical strake fin disposed circumferentially around a portion of the tubular pole along the longitudinal axis. The system further includes couplers disposed on the tubular pole. The couplers are configured such that each coupler has a first portion with a slot configured to receive an upper portion of the helical strake fin and a second portion configured to removably coupled to a threaded attachment point of the tubular pole. In addition, each coupler is configured to position a portion of the helical strake fin substantially perpendicular to a surface of the tubular pole.

摘要： The present disclosure generally relates to flexible drainage trap assemblies and methods for constructing and installing such drainage traps. In one exemplary embodiment, a flexible drainage trap assembly includes a plumbing fixture connector, a discharge joint, and a trap portion connecting the plumbing fixture connector and discharge joint. The trap portion is shaped in such a way that it is operable to retain a pool of water inside the trap portion. The disclosed flexible drainage assemblies include a flexible portion that has a substantially smooth inner surface.

摘要： A hose assembly includes an inner core tube, a metal outer tube, a first coupling member, and a first collar. The first coupling member has an inboard nose portion extending into a first end of the inner core tube. The metal outer tube surrounds the inner core tube and terminates at a first end axially inward of the first end of the inner core tube, with an outer cavity disposed between the inner core tube and the metal outer tube. The first collar has an outboard clamping portion surrounding the nose portion for clamping retention of the first end of the inner core tube therebetween, and an inboard venting portion welded to the first end of the metal outer tube, with the inboard venting portion including a venting port in fluid communication with the outer cavity.

摘要： A ventilation system for insulated pipe or pipeline to prevent corrosion thereof is discussed. The ventilation system can include an outer skin wrapped around the insulated pipe or pipeline, the outer skin separated from the insulation pipe by stand-off supports to form an annular chamber within the system. The system has a vent screen along a bottom side of the outer skin and a gable running along the top side of the outer skin, the gable having a number of openings therethrough to allow air to flow in through the vent screen, through the annular chamber and out through the gable openings, drawing moisture from the insulation thereby preventing corrosion of the pipe or pipeline.
