    摘要: The sealing device includes: an outer peripheral ring 2000 that is in contact with a side wall surface of an annular groove 4100 at a low pressure side (L), and slides with respect to an inner peripheral surface of a shaft hole in a housing 5000 through which a shaft 4000 is inserted. An inner peripheral ring 3000 made of a rubber-like elastic body that is in contact with an inner peripheral surface of the outer peripheral ring 2000 and a groove bottom surface of the annular groove 4100, respectively. The outer peripheral ring 2000 is formed on its outer peripheral surface with a concave portion 2220 which extends from an end of a high pressure side (H) to a position which does not arrive at an end of a low pressure side, so as to introduce fluid thereinto from the high pressure side.

    摘要: A sealing assembly includes a seal support having a support ring made from an elastomeric material, at least one seal element having a ring made from a polymer material, and an abutment ring against which a radial portion of the seal element axially abuts. The seal element is connected in a materially-bonded manner to the support ring along a first radially outer portion of the seal element, and the seal element axially abuts on the abutment ring along a second radially inner portion of the seal element. The seal element and the abutment ring are free of any connection along the second radially inner portion of the seal element.

    摘要: In accordance with the present invention, there is provided a fluid or liquid barrier packing system which is adapted to minimize VOC emissions, while also providing live-loading and continuous load monitoring functions. The components of the packing system (including the liquid barrier) are adapted to be installed in a traditional stuffing box of a valve utilizing a top entry method, and without the necessity of having to inject the liquid through any side ports of the valve. The packing system reduces leakage levels as required by low emission leakage specifications by creating a reverse osmosis effect, limiting the diffusivity of a gas through the packing elements of the system. Thus, the packing system of the present invention provides a simplified method to load and monitor a barrier in the stuffing box of the valve to slightly higher pressure than processed fluid pressure.

    摘要: A seal for use in temperature and pressure extremes is disclosed. It features springs internal to the sealing members and the ability to seal against pressure differentials from opposed directions. A spacer ring prevents contact from oppositely oriented seal components and at the same time prevents spring and seal collapse under extreme loading conditions. The seal assembly is self-centering in a downhole seal bore and can be used on tools delivered on wireline, where the insertion forces available are at a minimum. The seal can withstand pressure differentials in excess of 13,500 PSI and temperatures above 350 degrees Fahrenheit.

    摘要: A preload is applied to a thermoplastic seal to induce deformation of the seal. As the seal undergoes deformation (e.g., cold flow), it completes the seal. Thermoplastics such as PEEK, PEK, PPS, PEKEKK, and PET are examples of materials that may be used in the seal. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

    摘要: Axially spaced, pressure-energized seals in a sealing assembly are carried in a conventional seal assembly housing. The seals surround a rod that reciprocates through the housing to power a fluid pump. The seals are pressure-energized by a flowable sealant that is injected through the housing into a confined annular area defined between the seals. The sealant maintains worn seals in close sealing engagement with the reciprocating rod to prevent fluid or pressure loss from the pump. The sealant pressure resists the repeated flexing stresses exerted by the axial rod movement to minimize seal fatigue wear. Components of the seal assembly may be split to permit seal repair or replacement without requiring the removal of the rod from the assembly. The pressure and composition of the flowable, injectable sealant cooperate with the split seal assembly components to prevent leakage across the seal component splits.

    摘要: A packing ring is disclosed for sealingly engaging a movable rod member within a stuffing box having an internal cavity. In an embodiment, the packing ring includes a carrier and a sealing ring mounted to the carrier. The sealing ring is configured to sealingly engage with an outer surface of the rod when the rod is disposed within the internal cavity. The carrier includes a radially outer surface that is configured to sealingly engage with an internal surface of the stuffing box. In addition, the carrier includes a radially inner surface that is proximate to an outer surface of the rod when the rod extends through the stuffing box. Further, the carrier includes a plurality of lubrication grooves each groove extending from the radially outer surface to the radially inner surface and configured to convey a lubricant flow between the radially outer surface and the radially inner surface.
