Abstract
Disclosed herein are components, systems, and methods to improve performance and maintenance of high-pressure fluid systems, such as waterjet cutting systems. Specifically, embodiments of a valve cartridge are disclosed that include a pre-assembled body such that the valve cartridge is able to be inserted into a valve body of a valve assembly without the need for additional assembly or adjustment of the components of the valve cartridge, for example the poppet assembly of the valve cartridge.
Claims25
A valve cartridge comprising:
- a pre-assembled body including:
- a first portion having a first surface;
- a second portion having a second surface, the second surface opposite the first surface with respect to a first direction;
- and
- an outer sleeve that partially receives both the first portion and the second portion therein securing the first portion relative to the second portion such that an entirety of the outer sleeve is positioned between the first surface and the second surface with respect to the first direction, wherein the pre-assembled body defines a through hole extending from an inlet provided in the first surface to an outlet provided in the second surface along an axis that is parallel to the first direction;
- and
- a poppet assembly positioned within the through hole between the first surface and the second surface, the poppet assembly including a poppet member and a biasing member both positioned between the first surface and the second surface, and the poppet assembly coupled to the pre-assembled body such that when installed and in operation the poppet assembly is able to transition from a first configuration in which a first portion of the poppet member is enclosed within the first portion, a second portion of the poppet member is enclosed within the second portion, and fluid flow with a pressure greater than 20,000 psi through the through hole is blocked to a second configuration in which fluid flow with a pressure greater than 20,000 psi through the through hole is permitted,
- wherein transition from the first configuration to the second configuration includes movement of the poppet member along the axis.
5 more elements
A valve assembly comprising:
- a valve body defining a first recess and a second recess spaced apart from the first recess;
- a first valve cartridge and a second valve cartridge, each of the first and second valve cartridges including:
- a pre-assembled body including:
- a first portion having a first surface;
- a second portion having a second surface, the second surface opposite the first surface with respect to a first direction;
- and
- an outer sleeve that partially receives both the first portion and the second portion therein securing the first portion relative to the second portion, wherein the pre-assembled body defines a through hole extending from an inlet provided in the first surface to an outlet provided in the second surface along an axis that is parallel to the first direction;
- and
- a poppet assembly positioned within the through hole between the first surface and the second surface, the poppet assembly including a poppet member and a biasing member, the poppet assembly coupled to the pre-assembled body such that when installed and in operation the poppet assembly is able to transition from a first configuration in which fluid flow with a pressure greater than 20,000 psi through the through hole is blocked to a second configuration in which fluid flow with a pressure greater than 20,000 psi through the through hole is permitted, wherein transition from the first configuration to the second configuration includes movement of the poppet member along the axis,
- wherein the first recess defines a shape that corresponds to the first valve cartridge when the first surface of the first valve cartridge faces the valve body and corresponds to the second valve cartridge when the first surface of the second valve cartridge faces the valve body, and the second recess defines a shape that corresponds to the first valve cartridge when the second surface of the first valve cartridge faces the valve body and corresponds to the second valve cartridge when the second surface of the second valve cartridge faces the valve body.

- wherein the pre-assembled body defines a through hole extending from an inlet provided in the first surface to an outlet provided in the second surface along an axis that is parallel to the first direction, and
- wherein the pre-assembled body defines a maximum cross-sectional dimension measured in a second direction that is perpendicular to the first direction, a first portion of the maximum cross-sectional dimension is defined by the first portion, a second portion of the maximum cross-sectional dimension is defined by the outer sleeve, and a third portion of the maximum cross-sectional dimension is defined by the second portion;
- and
- a poppet assembly positioned within the through hole between the first surface and the second surface, the poppet assembly including a poppet member and a biasing member both positioned between the first surface and the second surface, and the poppet assembly coupled to the pre-assembled body such that when installed and in operation the poppet assembly is able to transition from a first configuration in which a first portion of the poppet member is enclosed within the first portion, a second portion of the poppet member is enclosed within the second portion, and fluid flow with a pressure greater than 20,000 psi through the through hole is blocked to a second configuration in which fluid flow with a pressure greater than 20,000 psi through the through hole is permitted,
- wherein transition from the first configuration to the second configuration includes movement of the poppet member along the axis.
