An improved method and apparatus for operating or setting equipment within a subsea marine wellhead from the surface having an indicating signal provided at the surface of the successful completion of such operation. The steps of the method include the lowering of a well component and the detecting and transmitting equipment on a running string from the surface; detecting the successful completion of the subsea operation, and transmitting to the surface of a signal signifying that the operations within the subsea well head have been successfully completed. The apparatus includes the running string, the detecting means which may be an acoustic detector or a ferrous metal detector or other suitable detector, a signal transmitter, means for supporting the detector and transmitter on the running string so that the well component can be properly lowered and positioned within the subsea wellhead and its proper landing, sealing or latching or other desired condition signalled to the surface to provide an indication that the operation has been completed.

A temperature sensitive valve having a body with an internal valve chamber being open through said body, an inlet extending into the valve chamber, a control outlet communicating with said valve chamber, and a bleed outlet communicating with said valve chamber, a bonnet having a bore secured to said body in surrounding relationship to the opening of the valve chamber through the body, a control sleeve positioned in said valve chamber and in said bonnet bore, means for sealing between the control sleeve and the interior of the valve chamber above and below the entry of said inlet into the valve chamber, said control sleeve defining a first valve seat in its lower portion, a second valve seat surrounding the entrance of the bleed outlet into said valve chamber, a valve member extending through said valve sleeve and having valve seat engaging surfaces for engaging said first and second valve seats, a first temperature sensitive material supporting said valve member in position out of engagement with said first valve seat, a second temperature sensitive material supporting said control sleeve in a first position and allowing it to move to a second position when exposed to temperature above a preselected temperature, said first temperature sensitive material upon reaching a elevated temperature which is less than said preselected temperature to release support of the valve member so that it moves out of engagement from said second valve seat and into engagement with said first valve seat to close flow between said inlet and said control outlet and open flow between said control outlet and said bleed outlet, said second temperature sensitive material releasing support of the control sleeve so that it moves to bring said valve member into engagement with said first valve seat when it reaches said preselected temperature and means biasing said valve member and said control sleeve so that excess pressure in said control outlet will move said control sleeve to open said second valve seat and allow such pressure to be bled from the valve chamber.

A tubular joint has a pair of tubular members (10, 12) with end hubs (14, 16) in opposed relation and secured by a clamp (22). A primary seal ring (40) has external tapered sealing surfaces (42, 44) engaging internal tapered sealing surfaces (28, 30) on the hubs (14, 16) to provide a primary seal. Secondary sealing surfaces (32, 36) on the hubs (14, 16) are engaged by O-rings (62, 64) as shown in FIG. 4 to seal against external fluid flow to the seal ring (40). O-rings (62, 64) permit internal fluid flow outwardly from the seal ring (40) as shown in FIG. 3.

() A travel multiplying device () has at least one outer pipe (), one inner pipe () and one intermediate pipe () positioned between them, which can be moved relative to each other in the longitudinal direction () each by a particular distance of travel (-) with at least one cut-out formed (-) between facing surfaces () of each pipe (), which cut-outs show different gradients () relative to a transverse plane () through the pipes (), and which are coupled with each other by at least one movement linking element (-) to link the movements of the pipes. By such a travel multiplying device, a small movement of one element is transformed into a magnifying movement of another element in a simply designed and reliable manner.

A high torque rotating actuator is disclosed. The high torque rotating actuator has a variable helix angle that allows the actuator to generate greater torque near the end of its travel when it is needed to close a valve or operate a choke. The high torque rotating actuator is designed for use with valves and chokes. In a second embodiment, a high torque rotating actuator is configured to give a shorter overall assembly. As in the preferred embodiment, a variable helix angle is used to generate greater torque near the end of its travel when it is needed to close a valve or operate a choke.

An improved gate valve having a body with a gate positioned therein to reciprocate between positions opening and closing flow through the body, a pressure responsive actuator connected to move the gate stem, a manual override stem and an overriding drive connection connecting both the actuator and the manual override stem to the gate stem so that the gate stem and gate are moved by both the actuator and by the manual override stem independently of the actuator. A modified form of the invention is provided for directly connecting to an extension of an actuator stem for operating a valve manually. In another modified form, camming element and a camming extension are provided to increase the forces providing release of the paddles from within a groove on the interior of the housing so that the locking action of the paddles do not prevent proper operation of the mechanism.

A valve actuator with an emergency shutdown feature incorporates shutdown of the valve when a sensed line pressure is outside of high- and low-pressure trip points. The actuator can be manually tripped. The actuator can be tripped in the event of a fire or, incorporating a solenoid, a trip can be accomplished with an appropriate signal. Once tripped, the actuator requires manual reset. The normal open and closed operation of the valve cooperates with a clutching mechanism which is part of the trip system. The preferred embodiment of the clutching system is a torsion spring or springs which normally allow movement in one direction but not in the other unless acted upon by the tripping system.
