Abstract
An emergency shutdown valve actuator includes a support and a fluid activated actuator drive secured to the support. Clamps are provided for clamping the support onto a tubular member. A drive key is provided which is adapted to couple the actuator drive and a female receptacle of a valve member, such that movement of the actuator drive is transmitted via the drive key to the valve member to move the valve member between an open and a closed position. The actuator drive is coupled to a fluid source controlled from a remote control panel such that fluid is supplied to activate the actuator drive in the event of an emergency.
Claims6
An emergency shutdown valve actuator, comprising:
- a support;
- a fluid activated actuator drive secured to the support;
- means for clamping the support onto a tubular member;
- and
- a drive key adapted to couple the actuator drive and a female receptacle of a valve member, such that movement of the actuator drive is transmitted via the drive key to the valve member to move the valve member between an open and a closed position;
- and
- means for coupling the actuator drive to a fluid source controlled from a remote control panel such that fluid is supplied to activate the actuator drive in the event of an emergency.
An emergency shutdown valve actuator, comprising:
- a support having a seat surrounded by a protective cage;
- a fluid activated actuator drive mounted on the seat of the support and protected by the protective cage;
- clamps secured to the support, whereby the support is clamped onto a tubular member;
- and
- a drive key adapted to couple the actuator drive and a female receptacle of a valve member, such that movement of the actuator drive is transmitted via the drive key to the valve member to move the valve member between an open and a closed position;
- fluid line couplings for coupling the actuator drive by fluid lines to a fluid source controlled from a remote control panel such that fluid is supplied to activate the actuator drive in the event of an emergency;
- and
- a handle connected to the drive key, thereby permitting manual activation by personnel via the handle as an alternative to the actuator drive.
