摘要： Disclosed is a flexible joint for sealing two conduits. One half of the joint includes an annular seal gland with an outer surface defining a static seal face. The other half of the joint includes an inner race member having inner and outer bearing surfaces, the inner surface spaced apart from and generally opposing the outer surface of the seal gland and having a region defining a dynamic seal face. An annular bellows constructed of a plurality of convolutions having varying convolution heights is disposed between the first and second seal faces to form a low leakage seal. The heights of the convolutions decrease in the direction of the first to the second seal faces.

摘要： A flexible joint 13 is employed to sealingly connect a pair of tubular members 16, 18 while still permitting limited articulated movement therebetween. The flexible joint 13 includes a housing 26 with upper and lower ring-like plates 32, 34 coaxially arranged about the tubular members 16, 18. A pair of annular elastomeric bearings 40, 42 are positioned within the housing 26 and act against shoulders 44, 46 of the tubular members 16, 18 to flexibly retain the tubular members 16, 18 within the housing 26. A bellows 20 sealingly couples the tubular members 16, 18 together while permitting movement therebetween. An annular chamber 56 formed between the bellows 20 and housing 26 is filled with a fluid, such as silicon or oil. Means is provided for adjusting the volume of the chamber 56 or volume of fluid in the chamber 56 to maintain an approximately zero pressure differential across the bellows 20.

摘要： A pipeline safety joint to provide a controlled point of weakness in at least one pipeline, said safety joint comprising a pair of tubular mandrels sized to be securable to a pipe-end of a pipeline, a portion of one mandrel being insertable into a part of the other mandrel thereof, to provide fluid communication between said pipe-ends. A latch mechanism on the portion of one mandrel is engagable with the part of the other mandrel, to hold said mandrel against axial separation. Retaining means on said one mandrel hold the latch mechanism in engagement. At least one seal assembly includes a metal sealing ring positioned to seal between a radially outer and inner substantially cylindrical surfaces on the mandrels. An annular cylinder and a co-operating annular piston formed on one mandrel and on a ring attached to the mandrel, to form a pressure compensation chamber surrounding said portion rings provide a fluid tight seal between said annular piston and cylinder. A fluid passage provides communication between the interior of said one mandrel and the compensation chamber, the seal assembly and the compensation chamber being dimensioned whereby forces produced to separate said mandrels of a pair of fluid pressure within the mandrels are equalized by the pressure compensation chamber. Frangible tubular bolts normally hold the mandrels in interengagement, break when a predetermined stress is applied thereto, the piston and cylinder then moving axially relative to one another to allow limited axial movement between said mandrels, sufficiently to permit the retaining means to move axially to release said latch mechanism. The interior is filled with a waterproof grease or jelly.

摘要： A pipeline safety joint to provide a controlled weakness in a pipeline in which a pair of tubular mandrels are connectable to first and second pipe-ends. A portion of the first mandrel of a pair is insertable in a part of the other and a latch mechanism is provided on said portion engageable with the part of the other mandrel of the pair to hold the mandrels against axial separation. A retaining shoulder on the first mandrel retains the latch mechanism in engagement and a tubular sealing is positioned to seal the two mandrels.A fluid-tight pressure compensation chamber surrounds said portion of the first mandrel and is engageable directly or indirectly on said one mandrel and said other mandrel of the pair. A fluid passage provides communication between the interior of the mandrel and its associated pressure compensation chamber, the seal and its associated compensation chamber being dimensioned whereby forces produced to separate the mandrels of a pair are substantially equalized by the fluid pressure appearing in the fluid compensation chamber. Frangible securing means, such as a bolt, normally holds the two mandrels in interengagement but break when a predetermined stress is applied, the pressure compensation chamber being axially crushable when the frangible means break, thereby allowing limited axial movement between the mandrels, sufficiently to permit the retaining shoulder to move axially to release the latch mechanism, thereby to allow the mandrels to disengage from one another.

摘要： A rotary joint is provided which is particularly useful in deep-sea diving suits, and which can be constructed in such a way such that resistance to rotational movement or the potential for leakage, does not increase substantially with external pressure on the joint. Preferably, the joint has a sealing member, a retaining member, and a central member disposed axially between the sealing and retaining members. The central member has an annular first end dimensioned and axially slidably mounted on a retaining end of the retaining member so as to define a first variable volume chamber therebetween. The central member also has a second end with inner and outer extending annular bearing members, each concentric with, and normally rotatably abutting a corresponding sealing surface portion on the sealing member, so as to define annular side walls of a second chamber. The second chamber is interconnected with the first chamber.

摘要： A conduit-cleaning assembly has a swivel coupling connected between a high-pressure hose and a conduit-cleaning nozzle. This coupling has an outer end tube connected to the hose, an intermediate outer tube threaded with the outer end tube, and an inner tube connected to the nozzle and forming with the outer tubes an axis-defining passage for liquid to flow into the nozzle from the hose. This inner tube is partially received in the outer tubes and has an inner-tube end whose outer edge engages an annular seal whose outer periphery is locked to the outer end tube. A bearing is provided between the inner tube and the intermediate tube to allow the parts to rotate relative to each other. The annular seal has a pair of opposite pressure-equalizing surfaces both exposed to the full pressure inside the swivel.

摘要： This invention provides a pipe joint which includes a first pipe end and a second pipe end juxtaposed in substantial alignment. The pipe joint is capable of providing for movement of one pipe end with respect to the other, and also for pressure-compensation. A sleeve member spans between and externally of both pipe ends. Two annular ring structures are positioned between the pipe ends and respective ends of the sleeve member. Sealing surface engagement takes place between each annular ring structure, its respective pipe end, and the sleeve member. Articulating means are provided for interconnecting each annular ring structure with the opposite pipe end, thereby to permit the pressure-compensation.

摘要： A pipe joint with a ball socket, a ball pin, and a socket nut for connecting the socket and pin together. The fluid passage extending axially through the ball socket and ball pin are sealed against leakage around the socket nut by packing rings. The end of the ball pin that is received in the ball socket is flared outwardly to allow for angular movement of the pin relative to the socket. The existance of a seal between the flared end of the pin and the socket causes a pressure differential urging the ball and socket to move apart. In order to overcome this danger, a channel extends from the flow passage in the ball pin to the area between the socket and the pin to reduce the pressure differential tending to cause separation of the elements in the joint.
