Auto shutoff device

Номер: US20130146166A1
Автор: Ashwini Sinha, Douglas Charles Heiderman, Serge Campeau
Принадлежит: Praxair Technology Inc

This invention is directed to an auto shut off device which includes a restrictive flow orifice (RFO) disc designed to restrict and isolate gas flow. The RFO disc is designed to flex in response to a specific pressure drop that develops as a result of a system failure. When the failure occurs, the RFO disc flexes into a sealed position which blocks the discharge flow path. In this way, the RFO disc functions as an auto shut off device that confines the gas upstream of the disc.

A method of deactiving an underwater hydraulic device provides a hydraulic device that is capable of being operated under water, the device having a hydraulic cylinder with a pushrod and a piston. The device is lowered below a water surface with a hose reel that is located at the water surface area such as on a marine vessel. The hose reel includes first and second hydraulic hoses that connect to the cylinder on opposing sides of the piston. Fluid flow in the first and second hydraulic hoses is continuously monitored. The ratio of the volume of fluid flowing into the cylinder from one side of the piston to the volume of fluid flowing into the cylinder from the other side of the cylinder is continuously calculated with a computer or controller. The hydraulic device is deactivated if the ratio varies from a preset value. One embodiment includes a plurality of flow meters for measuring fluid flow to and from one or more hydraulicly powered apparatuses.

The present invention relates to an anti-shake flow-limiting cutoff valve, comprising a flow stop valve, a cutoff valve and a check structure. Said flow stop valve comprises a valve body, a valve seat, a piston and a biasing component. The check structure is arranged downstream said flow stop valve to prevent fluid from flowing back. In case of a sudden excessive water flow, the flow stop valve is closed under impact of excessive water pressure to block the water flow. At this time, since the liquid flow in the pipeline is suddenly blocked, the liquid flow remaining in a pipeline downstream the flow stop valve tends to form a reverse flow to impact the flow stop valve, thus shaking the flow stop valve, which may further lead to insufficient close or damage of the flow stop valve. 1.

A pressure reducing valve includes a piston disposed in a cylinder chamber; a valve element that is coupled to the piston and opens and closes a valve seat; a valve spring that biases the valve element in a direction in which the valve element is moved away from the valve seat; and a biasing member that biases the valve seat toward a side opposite to the piston. The pressure reducing valve is configured to reduce a primary pressure of a fluid to a secondary pressure. The valve seat is disposed such that the valve seat reciprocates in the same direction as a direction in which the valve element reciprocates in the primary pressure chamber. As a difference between the primary pressure and the secondary pressure increases, the valve seat moves toward the secondary pressure chamber.

A method of deactiving an underwater hydraulic device provides a hydraulic device that is capable of being operated under water, the device having a hydraulic cylinder with a pushrod and a piston. The device is lowered below a water surface with a hose reel that is located at the water surface area such as on a marine vessel. The hose reel includes first and second hydraulic hoses that connect to the cylinder on opposing sides of the piston. Fluid flow in the first and second hydraulic hoses is continuously monitored. The ratio of the volume of fluid flowing into the cylinder from one side of the piston to the volume of fluid flowing into the cylinder from the other side of the cylinder is continuously calculated with a computer or controller. The hydraulic device is deactivated if the ratio varies from a preset value. One embodiment includes a plurality of flow meters for measuring fluid flow to and from one or more hydraulicly powered apparatuses. In one embodiment outputs of the flow meters are analyzed to determine if the hydraulic system has a leak, and if a leak is detected, a warning is issued and/or one or more of the connected hydraulically powered apparatuses are shut down, and/or the hydraulic power supply is shut down.
