In a severe earthquake, the seismic vibrations will cause the steel ball to break away from the magnet and fall onto the slide trigger. The weight of the steel ball and slide trigger will be pushed down and the slide trigger shall engage a momentary switch that will send voltage to a normally open motorized ball valve and cause it to close. The apparatus can be reset by manually pulling upward the lift handle towards the top cap. Resulting in the momentary switch to disengage and the voltage will seize to power the normally open motorized ball valve, causing it to go back to its normally open state.

  • Publication number: 20130206236
    Abstract: The various embodiments herein disclose a system and a method for regulating a flow of fluid stream in fluid storage and dispensing systems. The system comprising a valve arrangement including a compressed air unit bloated by a connecting air inlet tube, a frame and a valve elevating means to mount the valve arrangement on the frame, several sensors to detect one crisis factor, a communication unit, a data logger and processing unit, a remote management system and several actuators to regulate the operation of the valve arrangement. The valve arrangement shuts down the outflow of fluid stream on receiving a valve shutdown signal from one of the sensors and data processing unit in case of a crisis detection. The data processing unit informs the remote management system to take adequate safety measures through the communication unit.

  • Patent number: 8485210
    Abstract: A water scavenging system (1) for removing water from an aircraft fuel tank (2), the water scavenging system comprising: a water line (10); and a valve (20) which is configured to control the flow of water in the water line in response to a change in an effective angle of the valve. In use, the valve opens automatically in response to an increase in the effective pitch of the aircraft during take off and climb. The valve comprises: a pendulum (40); and a valve closure member (46) which is coupled to the pendulum such that a change in the angular position of the pendulum relative to the water line causes the valve closure member to move from a closed position in which the valve closure member impedes the flow of water in the water line to an open position in which water can flow through the valve.

  • Patent number: 8467907
    Abstract: A self-contained valve actuator of the present invention can comprise an actuator component. This actuator can be linear or quarter turn depending on the valve. The actuator can be double acting which means the piston will move once to open and once to close. The self-contained valve system uses hydraulic fluid to operate the valve. The valve system is directly powered with electric power from a battery. Solar panels are also incorporated to capture solar energy and convert this energy into electrical energy. This converted electrical energy is stored in the battery which enables the battery to continuously supply energy while substantially reducing the possibility of exhausting battery power. This resupply of electrical energy and the use of the hydraulic fluid creates a self-contained valve actuation system.

  • Patent number: 8237443
    Abstract: The position of a movable downhole component such as a sleeve in a choke valve is monitored and determined using an array of sensors, preferably Hall Effect sensors that measure the strength of a magnetic field from a magnet that travels with the sleeve. The sensors measure the field strength and output a voltage related to the strength of the field that is detected. A plurality of sensors, with readings, transmits signals to a microprocessor to compute the magnet position directly. The sensors are in the tool body and are not mechanically coupled to the sleeve. The longitudinal position of the sleeve is directly computed using less than all available sensors to facilitate the speed of transmission of data and computation of actual position using known mathematical techniques.
