摘要： A liveload assembly having a stack guide with a thread on the exterior side wall, a plurality of compressible belleville washers stacked inside the stack guide, and a retainer cap having a thread on an inner side wall for matingly engaging with the stack guide to hold the belleville washers in compression. The gland follower of a fluid flow apparatus is liveloaded by placing the liveload assembly over the bolt extending upwardly from the gland follower. A nut is threaded on the bolt to contact the stack of belleville washers and the retainer cap is unscrewed to a second position on the stack guide and fixed by turning a set screw through a bore in the cap and against the side of the stack guide. Compression of the gland follower is monitored by viewing the relative movement of the stack of belleville washers through a longitudinal slot in the side wall.

摘要： An improved live load packing system for sealing an operating valve member in a fluid valve. A packing follower includes a base and a guide sleeve with a non-metallic inner liner adapted for slidable engagement on the operating valve member. A series of Belleville disk springs slidably engage the guide sleeve outer diameter and maintain concentric mounting during loading of V-type TFE packing members to ensure uniform concentric spring loading and to prevent undesired side loading. A window permits viewing the position of the guide sleeve and inner liner during packing loading adjustment so that optimum loading can be attained and maintained when the viewer notes the top edge of the guide sleeve and inner liner is flush with the top surface of the packing flange.

摘要： A sootblower hub having packing for sealing between a sootblower feed tube and lance tube. A packing gland is used which provides a live loading feature for exerting an axial force on the packing. The packing gland is comprised of elements which can be separately assembled in a manner which maintains a preload on the packing loading spring, even when it is disassembled from the sootblowing mechanism. Once the packing gland is installed into a sootblower carriage a preload maintaining member can be actuated to enable the axial loading force created by the spring to be transferred to the packing.

摘要： A sealing ring device is provided for a fluid valve having a piston (2) reciprocating within a cylinder (1), wherein the piston (2) includes a valve cone (2c) adapted to contact a valve seat (11). In order to seal the inner space of the cylinder (1) located behind the piston (2) from an inlet/outlet passageway (A), a resilient sealing ring (5) is disposed in an annular groove (4) opening into the cylinder (1) around the rear end (2a) of the piston (2). A press ring (7), which extends above the rear end (2a) of the piston (2), contains the sealing ring (5) in the annular groove (4). A spring element (8) rests on the press ring (7). A piston rod (3) is guided in slidable manner through the piston (2). A stop (9) is attached to the rod (3) above the rear end (2a) and opposite the top side of the spring element (8). Downward movement of the rod (3) past the end position of piston (2) causes the stop (9) to compress the spring element (8), and the resulting force is transferred by the press ring (7) to the sealing ring (5) to expand the sealing ring (5) against the piston (2) and the cylinder (1).

摘要： A high pressure sealing system is disposed between a housing and a reciprocating member. One version has a reciprocating plunger and in another version is a reciprocating piston associated with a free floating piston. In the one embodiment, the reciprocating plunger is directed through a housing that includes spaced spring biased seal assemblies each including a wedge member that is spring biased against a continuously circumferentially formed seal ring having an inner radial seal surface sealing the reciprocating plunger and an axial seal surface that in one case is sealed against the housing and in another case is sealed with respect to an intermediate seal carrier with a cavity defining a buffer space and which carries two static o-ring seal members for sealing against the housing and another seal ring that has an inside radial seal surface in engagement with the piston and an axial surface in sealing engagement with a cylinder; each seal ring a convoluted surface to prevent it from pinching between the relatively reciprocating member and housing. The piston in the other embodiment is further associated with a floating piston having an oil cavity on one side thereof and a gas chamber on the other side thereof and the floating piston carries a pair of spaced seal assemblies each including a spring biased wedge and a continuous annular seal ring of the type previously described that seals with respect to a seal support rib on the floating piston and a housing member that surrounds the floating piston.

摘要： A sealing arrangement for a reciprocating piston pump utilizing at least two sets of seals separately supported at spaced apart locations along the length of the pump cylinder. One of the sets of seals located rearwardly from the other with respect to the discharge end of the pump cylinder is enclosed within a chamber formed by a sleeve positioned around the pump plunger. This rearward set of seals is hydraulically pressurized radially inwardly by the aforesaid sleeve during the discharge stroke of the plunger, thereby creating a sealing clearance which is kept constant and providing an accurate and effective seal.

摘要： A novel shaft seal suitable for use on agitator shafts and pump shafts such as those commonly found in industrial chemical process equipment, said seal comprising a conventional mechanical seal in combination with packing of a particular material of construction, configuration and which is held under substantially constant compression, such that when fluid is provided under pressure into a stuffing box containing such packing, the fluid will flow through the packing into the process stream with sufficient velocity to prevent process fluid from flowing back into the stuffing box, and yet with insufficient volume rate of flow to cause significant dilution of the process fluid.
