  • Packing having seal tongue
    Publication number: 20070034078
    Abstract: A cylinder packing is clamped between two parts of a casing of a cylinder and a piston is received between the two parts. The piston has a shaft which extends out from the casing of the cylinder. The packing includes a seal portion extending from an inner periphery thereof and being in contact with a top and a bottom of the piston. A seal tongue extends from the inner periphery of the packing and is in contact with inside of the two parts so as to seal the conjunction portion of the two parts of the casing.

  • Packing assembly for cylinder casing
    Publication number: 20070034079
    Abstract: A packing assembly for a cylinder is clamped between two parts of a casing of a cylinder between which a piston is received. The piston has a shaft which extends out from the casing of the cylinder. The packing assembly includes two seal frames connected to the two parts and the packing is clamped between the two seal frames. The packing includes a seal portion in contact with a top and a bottom of the piston. A seal tongue extends from the inner periphery of the packing and is in contact with inside of the two parts so as to seal the conjunction portion of the two parts of the casing. The seal frames are tightly engaged with the two parts of the cylinder so that the two respective connection peripheries of the two parts do not need to be machined precisely.

  • Valve having an inner washing structure
    Patent number: 6578598
    Abstract: A valve having an inner washing structure, includes a receiving chamber. The valve is formed with at least one washing hole which is located at a position opposite to the tangential plane of the outer diameter of the ball, and is communicated with the receiving chamber. Thus, the valve can be washed through the washing hole directly, without having to detach the valve, thereby facilitating the washing work without wearing the inside of the valve.
