Abstract
An apparatus and method for valve cartridge extraction from a valve assembly, wherein the assembly includes a valve member body, a cartridge, and a valve cartridge extraction (VCE) tool comprising at least one pin disposed on the upper surface of the VCE tool. During cartridge removal, the VCE tool is uncoupled from the valve member body and is coupled to the cartridge with the at least one pin. The cartridge is rotated with the coupled VCE tool to assist in cartridge removal. The valve assembly may also include a hood covering the VCE tool.
Claims30
A valve assembly, comprising:
- a valve member body with an opening defined therethrough;
- a cartridge configured to fit into the valve member body through the opening;
- and
- an extraction tool with one or more pins defined on an upper surface, the extraction tool configured to couple the cartridge to the valve member body,
- wherein the pins are configured to engage the cartridge to aid in coupling and decoupling the cartridge and the valve member body.
An extraction tool for removing a cartridge from a valve body, comprising:
- a hollow cylindrical body having an upper surface, a cylindrical outer sidewall, and an inner surface;
- one or more pins perpendicularly disposed on the upper surface of the body, each pin having a free distal end configured to interact with the cartridge;
- and
- one or more outward protrusions extending from the cylindrical outer sidewall, wherein each protrusion corresponds to a respective pin.
A valve assembly comprising:
- a valve member body defining:
- a inlet port;
- an outlet port directed 90 degrees away from the inlet port;
- and
- a loading port disposed between the inlet and outlet port;
- a valve cartridge configured for insertion into the loading port of the valve member body such that the valve cartridge resides in a flow path of the valve member body, the valve cartridge defining a plurality of notches on a proximal portion thereof;
- and
- a valve cartridge extraction tool configured to lodge the valve cartridge in the valve member body through the loading port, the valve cartridge extraction tool defining a plurality of pins each having a distal notch,
- wherein the valve cartridge extraction tool is configured to remove the valve cartridge from the valve member body by coupling the plurality of pins to the plurality of notches of the valve cartridge for rotating the valve cartridge extraction tool.
A valve assembly comprising:
- a right-angled valve member defining a flow path extending between an inlet and an outlet;
- a port defined in the right-angled valve member and extending into the flow path;
- a cartridge lodged in the port;
- and
- an extraction tool configured to input the cartridge in the port, the extraction tool including one or more pins, each pin having a free distal end configured to interact with the cartridge,
- wherein the one or more pins of the extraction tool can be used to dislodge the cartridge from the port.
A valve assembly comprising:
- a valve member body;
- a cartridge configured to mount in the valve member body;
- and
- an extraction tool with a plurality of pins, the extraction tool configured to couple the cartridge to the valve member body,
- wherein the plurality of pins are configured to engage the cartridge to aid in coupling and decoupling the cartridge and the valve member body.
