The gland (10) is so arranged as to be pressed against the packing (9) by means of gland bolts (17) interacting with the aforementioned holes.
one-piece gland of a valve
flanged gland of a valve
The seal member is at least partially positioned in the gland structure.
A recess (8) is provided in the flange for a packing (9) around the slide (2), and a gland (10) is so arranged as to be applied against the packing (9).
The present invention provides for a method for detecting leaks in a stuffing box of a two-stroke engine.
This stuffing box seal causes substantially less wear on the piston rod (1) and is itself more durable.
Split packing followers for use with valves are disclosed.
The piston (31), housing (32), and packing follower cap (30) create a chamber (46).
When sufficient fluid flows into the chamber (46), it pushes the piston (31) away from the packing follower cap (30) so that the bottom (57) of the piston (31) can push against the packing (19).
The first and second members include complementary interlocking structures that are configured to mechanically couple the first and second members to form the packing follower.
Preferably, the packing follower cap (30) has a channel (54) for fluid from a remote source to flow from a hose attached to the channel (54).
A packing nut (42) having a central bore is sized to receive the valve stem and includes a threaded outer surface positioned to engage the second counterbore of the packing box.
The mechanical seal employs an inboard mounted spacer element (74) to provide axial and radial spacing between a holder (50) and a gland (40).
A canned electric rotating machine is suitable for use in an electric motor for driving a seal-less pump (non-seal pump) having a rotor chamber filled with a high-pressure pump working liquid.
A floating brush seal (101) is provided for a gas or steam turbine or a compressor that typically includes labyrinth seals (307).
A seal system includes a first connector member, a second connector member, a gland structure, and a seal member.
The gland structure is defined by the first connector member and the second connector member, and is located between the first and the second seal structures.
A liquid tight connector (10) for pass through cable, tubing or rods (26) includes a body (11), a compression nut (23) and a gland (15).
A buffer seal arrangement (60) is provided for improved buffer sealing of oil sump seals (39) in gas turbine engines.
Both seals are of active type, and their helical channels are located on the internal surfaces of rotor rings.
Each outer gland segment has an arcuate wall with a groove formed therein, a rear wall extending radially inward from the arcuate wall, and a pair of connection members.
Sealing system may also include a grease filled chamber (120) between the seal and the bearing, and a packing gland (130) located adjacent the bearing on the side of the bearing opposite the seal.
The first and second seal structures are configured to deform the seal member into the gland structure in response to connection of the first connector member and the second connector member.
In addition to providing selected axial and radial spacing, the spacer element (74) promotes or enhances fluid circulation in a process chamber formed between the gland (40) and holder (50) by rotating about the shaft.
