  • Patent number: 10598289
    Abstract: The disclosed spool valve is used especially in conveying systems comprising conveying pipes (6, 7) and includes a spool (1) which allows the conveying cross-section of the conveying pipe (6, 7) to be closed. The spool (1) has at least one through-hole (33). The conveying pipe (6, 7) is sealed from the spool (1) by at least one sealing ring (27, 28). Said sealing ring (27, 28) surrounds the conveying line (6, 7) and includes a washer-shaped sealing portion. Said sealing portion lies flat on the spool and seals under the effect of the difference between the pressure in the conveying line (6, 7) and the ambient pressure.

  • Patent number: 10527228
    Abstract: A protection mechanism for a lubricant reservoir is mounted within a valve protection chamber disposed on an actuator. The protection mechanism includes a valve actuating plate and an elastic member biasing the valve actuating plate upwards. The actuator is pushed upwards by a rising level of lubricant as the lubricant reservoir is filled. When the reservoir is full, the actuator causes the valve actuating plate to contact a valve stem. The valve actuating plate pushes the valve stem up to shut off a flow of lubricant to the reservoir through the shut off valve. During an overfill event the actuator shifts upward due to the rising level of the lubricant in the reservoir. As the actuator shifts upward, the elastic member compresses such that valve actuating plate remains static relative to the lubricant reservoir as actuator rises.

  • Patent number: 10415711
    Abstract: The invention relates to a mechanical energized sealing ball valve comprising a seat, a ball assembly, and a single valve stem that operates both the sealing member and the ball. The ball comprises a ball and a sealing member. The valve stem drives the ball to rotate between open position and close position. When the ball reaches the close position, the sealing member, operated by the same valve stem, moves away from the ball to press and sit against the seat. The invention has the advantages that: the valve has a compact structure, the friction-free on/off is achieved, the mechanical energized sealing force is even and reliable, the ball is retracted and locked in the opening position to protect against turbulence-induced damage, low operating torque, the open/close operation is rapid, and the valve stem seal operates simply and reliably.
