Abstract
Fluid apparatus and related methods are disclosed. An example fluid apparatus includes a valve body defining a fluid flow passageway and a plurality of valve seats. A flow control member is positioned in the fluid flow passageway of the valve body. The flow control member having a plurality of disks. A respective one of the disks moves relative to a respective one of the valve seats to control fluid flow through the valve body. The flow control member is adjustable relative to a longitudinal axis of the valve body to provide a preload to the disks. Each of the disks has a cracking pressure corresponding to the preload.
Claims19
A fluid apparatus comprising:
- a valve body defining a fluid flow passageway and a plurality of valve seats;
- and
- a flow control member positioned in the fluid flow passageway of the valve body, the flow control member having a plurality of disks, a respective one of the disks to move relative to a respective one of the valve seats to control fluid flow through the valve body, the flow control member being adjustable relative to a longitudinal axis of the valve body to provide a preload to the disks, each of the disks has a cracking pressure corresponding to the preload.
An apparatus comprising:
- a valve body defining a valve seat positioned in a fluid flow passageway between an inlet and an outlet and a threaded inner wall;
- and
- a flow control member positionable in the fluid flow passageway, the flow control member including:
- a body;
- a disk coupled to the body, the disk to seal against the valve seat to prevent fluid flow through the fluid flow passageway when a pressure at the inlet of the valve body is less than a cracking pressure of the disk, and the disk to move away from the valve seat to allow fluid flow through the fluid flow passageway when the pressure at the inlet of the valve body is greater than or equal to the cracking pressure;
- and
- a head having threaded portion to engage the threaded inner wall of the valve body to couple the flow control member to the valve body, the head being adjustable relative to a longitudinal axis of the valve body to provide a preload to the disk corresponding to the cracking pressure, the head including a plurality of passageways to allow fluid flow between a first side of the head oriented toward the inlet and a second side of the head oriented opposite the inlet.
An apparatus comprising:
- a valve body defining a valve seat positioned in a fluid flow passageway between an inlet and an outlet and a threaded inner wall;
- and
- a flow control member positionable in the fluid flow passageway, the flow control member including:
- a body;
- a disk coupled to the body, the disk to seal against the valve seat to prevent fluid flow through the fluid flow passageway when a pressure at the inlet of the valve body is less than a cracking pressure of the disk, and the disk to move away from the valve seat to allow fluid flow through the fluid flow passageway when the pressure at the inlet of the valve body is greater than or equal to the cracking pressure;
- and
- a head having threaded portion to engage the threaded inner wall of the valve body to couple the flow control member to the valve body, the head being adjustable relative to a longitudinal axis of the valve body to provide a preload to the disk corresponding to the cracking pressure, the head having an annular wall spaced from the body, the annular wall being attached to the body via a plurality of ribs, an outer surface of the annular wall having the threaded portion.
A method comprising:
- positioning a flow control member in a first housing of a fluid valve, the first housing having a plurality of valve seats and the flow control member having a plurality of disks, the valve seats and the disks being spaced along a longitudinal axis of the first housing, a respective one of the disks is to engage a respective one of the valve seats when the flow control member is positioned in the first housing;
- and
- adjusting a position of the flow control member relative to the longitudinal axis to vary a preload of the plurality of disks.
