Abstract
This invention is directed to an apparatus for controlling the discharge of pressurized fluids from the outlet of a pressurized vessel, and particularly directed to multiple fluid dispensing check valve devices within the vessel for storing and controlling the flow of fluid or gases out of the vessel.
Claims20
An apparatus for controlling the discharge of pressurized fluids from the outlet of a pressurized vessel, the apparatus comprising:
- a. a port body for communication with the outlet of a pressurized tank defining a fluid discharge path;
- b. a cylinder valve fixed in or upstream of the port body and adapted for movement between a sealing position that blocks fluid flow through the fluid discharge path and an open position that permits fluid flow along the fluid discharge path;
- c. a upstream diaphragm dispensing device defining an interior volume isolated from the pressure condition upstream of the valve element and engaged with the valve element to control the movement of the valve element in a manner that retains the valve element in the sealing position until a pressure differential between the interior volume of the diaphragm and the interior of the port body moves the valve element to the open position;
- and
- d. a downstream diaphragm dispensing device defining an interior volume isolated from the pressure condition upstream of the valve element and engaged with the valve element to control the movement of the valve element in a manner that retains the valve element in the sealing position until a pressure differential between the interior volume of the diaphragm and the interior of the port body moves the valve element to an open position.
A cylinder and a valve assembly for containing pressurized fluid and controlling the discharge of pressurized fluid from the cylinder, the cylinder and valve assembly comprising:
- a cylinder having a cylinder opening;
- a port body adapted for sealing engagement with the cylinder opening;
- a fluid inlet port defined by the port body and located outside the cylinder;
- a fluid discharge path defined by the valve body between the fluid inlet port and the fluid outlet port;
- a manually operated shut off valve for controlling fluid flow along the fluid discharge path;
- wherein said manually operated shut-off valve biases a cylinder valve into a sealing position that blocks fluid flow along the fluid discharge path and a plurality of sealed bellows, at least one located upstream and at least one located downstream of the cylinder valve along the fluid discharge path, the sealed bellows having one portion operably linked to a valve element to move said valve element to an open position when relative pressure between an interior and an exterior of the bellow expands the bellows and wherein the open position permits fluid flow along the fluid discharge path.
An apparatus for controlling the discharge of pressurized fluids from the outlet of a pressurized tank containing toxic hydridic or halidic compounds, the apparatus comprising
- a container for holding a pressurized fluid in an at least partial gas phase;
- an outlet port for releasing pressurized gas from the container;
- a gas flow path defined at least in part by an outlet port for delivering pressurized gas from the container;
- and
- a plurality of separate dispensing check valve devices, at least one upstream and at least one downstream of a cylinder valve, and a flow restrictor.
The apparatus of claim 17 wherein a conduit located within the container includes the restricted portion of the flow path.
The apparatus of claim 18 wherein a packing in the conduit provides the restricted flow path.
