  • Patent number: 10823309
    Abstract: Retractable handle assembly used in a valve of an Intermediate bulk container (IBC) includes a valve body, a valve core, and a valve stem. The valve stem is used to drive the valve core to move so as to open/close the valve. The handle of the handle assembly is connected to the valve stem and can be rotated around the central rotating axis of the valve stem. When the valve needs to be opened/closed, the handle is rotated around the central rotating axis to a deployed state to open/close the valve. The handle is rotated around the central rotating axis to a retracted state so as to reduce the space occupied by the valve for the valve to be welded to the liner bag or installed to IBC. The handle can be switched between a deployed state and a retracted state.

  • Patent number: 10001218
    Abstract: The present invention provides a hinged valve, comprising a handle, a valve body, a valve stem, a valve core, sealing rings, guide and a valve cover. The valve core is connected to the valve body by means of a hinge such that the valve core will be rotated around a rotation axis of the hinge. A locking hook and a positioning hole are provided on the valve stem. A positioning column, elastic buckles and guiding slot are provided on the guide. The positioning column is connected to the positioning hole of the valve stem and the guide is elastically assembled to the body of the valve stem under the effect of the elastic buckles of the guide, such that the guide and the valve stem will move synchronously without motion relative to each other. Rotating shafts and a guiding post are provided. The rotating shafts are rotatably connected to the connecting holes.

  • Patent number: 9534693
    Abstract: The present invention relates to a valve with a hinged valve core. The valve comprises a valve body, a valve core, an operating mechanism, a motion-transferring device and a locking device. The valve body is a housing. The housing is formed with a operating hole used to partially accommodate the operating mechanism and a channel having an inlet and an outlet. The valve core is connected with the valve body through a hinge. The operating mechanism is used to operate the valve core to be rotated around the central axis of the hinge to open/close the valve. The motion-transferring device is used to transfer actions on the operating mechanism to the valve core, and when the valve is closed or open, the valve core is locked on the valve body through the locking device. The valve of the present invention has a compact structure, is easy to operate, requires a small torque for opening and allows a large flow when opened.

  • Patent number: 9004448
    Abstract: A valve and valve cartridge assembly can provide an opening and closing operation with a low torque. The valve and valve cartridge assembly can be switched between a first transmission relationship and a second transmission relationship, and the first and second transmission relationships are formed between the top of the valve cartridge and a transmission device. The first transmission relationship is established so that the valve cartridge is driven to rotate axially. The second transmission relationship is established so that the transmission member drives the valve cartridge to carry out a squeeze sealing movement.

  • Publication number: 20130341545
    Abstract: A valve cartridge assembly comprises a valve cartridge (9) and a transmission device. A recess (90) is formed on the top of the valve cartridge. The transmission device is provided in the recess (90) of the valve cartridge. A first transmission relationship and a second transmission relationship are formed between the transmission device and the recess (90) of the valve cartridge. The first transmission relationship is established so that the transmission device drives the valve cartridge (9) to rotate axially. When the movement in the first transmission relationship is ended, the relationship between the transmission device and the valve cartridge (9) switches from the first transmission relationship to the second transmission relationship. The second transmission relationship is established so that the transmission device drives the valve cartridge (9) to carry out a squeeze movement, and the squeeze movement enables the valve cartridge to have a moving component at least in an axial direction.
