Underwater gate valve position indicator of the present invention is primarily adapted for use in containing the mating of rotary-type underwater gate valve actuator device, packet
Subsea production tree, manifold etc. are included, working principle is specific as follows:
When the equipment such as subsea production tree or manifold transfer operation, gate valve is typically in closed state, i.e. indicator graduation lines
16 in position shown in Fig. 2.When equipment seat is put into position, when needing Open valve, torque tool is extend into ROV using ROV and is revolved
Turn in 1 inner cavity of guide cylinder, four directions is engaged with the standard four directions 32 on worm shaft 2 in the standard on torque tool, on torque tool
Symmetrical fixture block is engaged with two card slots 41 corresponding on ROV rotary steering cylinder 1, forms reaction torque structure.Torque tool
On drive shaft drive worm shaft 2 to rotate counterclockwise by standard four directions 32, input power passes through the connecting shaft four directions on worm shaft 2
33 outputs are to the connecting shaft of gate valve driver, and at the same time, worm shaft 2 drives worm gear 5 along Fig. 1 by worm and gear screw thread pair
Certain angle rotationally clockwise, worm gear 5 is fixedly connected with indicating arm 23 by nut 27, screw V 29, drives and indicate
Bar 23 rotates together, and indicator graduation lines 16 are also rotated synchronously with indicating arm 23.In gate valve opening process, indicator graduation lines 16 by
Gate valve fully closed position turns to gate valve full open position, i.e. position Warning Mark " S " on direction board 15 as shown in Figure 2
Position Warning Mark " O " on direction board 15 shown in Fig. 3 is turned to, realizes the position indicating function of underwater gate valve opening process.
When needing to close valve, the drive shaft on torque tool drives worm shaft 2 to turn clockwise by standard four directions 32
Dynamic, input power is by 33 output of connecting shaft four directions on worm shaft 2 to the connecting shaft of gate valve driver, at the same time, worm shaft 2
Worm gear 5 is driven to rotate in an anti-clockwise direction certain angle in Fig. 1 by worm and gear screw thread pair, worm gear 5 passes through nut 27, spiral shell
It follows closely V 29 to be fixedly connected with indicating arm 23, indicating arm 23 is driven to rotate together, indicator graduation lines 16 also turn with indicating arm 23 is synchronous
It is dynamic.In gate valve closing process, indicator graduation lines 16 turn to gate valve fully closed position by gate valve full open position, i.e., by
Position Warning Mark " O " on direction board 15 shown in Fig. 3 turns to position Warning Mark " S " on direction board 15 shown in Fig. 2, real
The position indicating function of existing underwater gate valve closing process.
By the above-mentioned means, underwater gate valve position indicator of the present invention uses rotary motion auxiliary structure, it is inclined to overcome pointer
Rotatable indicator needs to have the problem of parts moving linearly on driver, simplifies gate valve driver design requirement, tool
Standby better adaptability；In addition, the position indicator only includes one group of drive structure of gear worm, it is not necessarily to connecting rod, rotary indicator
Equal accessory structures, structure is simple, volume compact；Worm and gear kinematic pair is completely built-in and seals off with briny environment, failure
Rate is low, high reliablity, can meet oil and gas development operating condition under ocean water well.
