Abstract

The utility model relates to a novel complete electric production tree produces valve under water, including little band pulley, step motor, disk seat, shell, big band pulley, retaining ring, hold -in range, flashboard, lead screw pole, valve pocket, spring, spring bracket, screw nut and bearing, the taeniola wheel is installed in step motor's pivot to the taeniola takes turns to to open there is the tooth's socket, big band pulley is installed on screw nut to it is fixed through the retaining ring, the flashboard welding is in the one end of lead screw pole, spring bracket passes through the fix with screw on the lead screw pole, screw nut passes through threaded connection with the lead screw pole, the flashboard adopts the copper alloy, the horizontal tooth of equidistance distribution on the hold -in range internal surface and the tooth's socket intermeshing on little band pulley and the big band pulley. The utility model discloses beneficial effect does: 1 ) safe and reliable, manufacturing is with low costs, 2 )Adopt the electric control, the reaction is applicable to the deep water field rapidly.

Description

A kind of underwater electricity production tree entirely produces valve

Technical field

This utility model relates to a kind of underwater oil equipment, particularly to a kind of underwater electricity production tree entirely Produce valve.

Background technology

Tradition subsea production tree all uses hydraulic control, when the depth of water exceedes certain limit, arises that Control delayed phenomenon, produce certain potential safety hazard, and tradition submerged production tree construction is complicated, Processing and manufacturing cost is high.

Utility model content

This utility model aims to solve the problem that the problems referred to above, it is provided that electricity production tree entirely produces a kind of underwater Valve, which overcomes many drawbacks of tradition production tree valve, and its technical scheme used is as follows:

A kind of underwater electricity production tree entirely produces valve, including small pulley, motor, valve seat, Shell, big belt wheel, back-up ring, Timing Belt, flashboard, wire lever, valve pocket, spring, spring support, Feed screw nut and bearing, described small pulley is arranged in the rotating shaft of motor, and opens on small pulley Having teeth groove, described big belt wheel to be arranged on feed screw nut, and fixed by back-up ring, described flashboard welds Being connected on one end of wire lever, described spring support is fixed by screws on wire lever, described leading screw spiral shell Mother is threaded connection with wire lever, and described bearing has two, is separately mounted to the two ends of feed screw nut.

Preferably, described flashboard uses copper alloy, the horizontal stroke that described Timing Belt inner surface is equally spaced Teeth groove on tooth and small pulley and big belt wheel engages each other.

This utility model has the advantage that

1) safe and reliable, processing and manufacturing low cost；

2) use electric control, be swift in response, it is adaptable to deep water field.

Symbol description

1. small pulley, 2. motor, 3. valve seat, 4. shell, 5. big belt wheel, 6. back-up ring, 7. Timing Belt, 8. flashboard, 9. wire lever, 10. valve pocket, 11. springs, 12. spring supports, 13. feed screw nuts, 14. bearings.

Detailed description of the invention

The utility model is described in further detail with example below in conjunction with the accompanying drawings:

As shown in Figure 1-2, a kind of underwater of the present utility model electricity production tree entirely produces valve, including Small pulley (1), motor (2), valve seat (3), shell (4), big belt wheel (5), back-up ring (6), Timing Belt (7), flashboard (8), wire lever (9), valve pocket (10), spring (11), spring support (12), feed screw nut (13) and bearing (14), small pulley (1) is arranged on motor (2) Rotating shaft on, and on small pulley (1), have teeth groove, big belt wheel (5) is arranged on feed screw nut (13) On, and fixed by back-up ring (6), flashboard (8) is welded on one end of wire lever (9), spring Support (12) is fixed by screws on wire lever (9), feed screw nut (13) and wire lever (9) Being threaded connection, bearing (14) has two, is separately mounted to the two ends of feed screw nut (13), Flashboard (8) uses copper alloy, the transverse teeth that Timing Belt (7) inner surface is equally spaced and small pulley (1) teeth groove and on big belt wheel (5) engages each other.

During use, valve seat (3) is accessed production system, control motor (2) work, stepping electricity Machine (2) drives feed screw nut (13) to rotate, so that wire lever (9) does directly by V belt translation Line moves, and wire lever (9) lower end and flashboard (8) are fixed, and so move to when flashboard (8) When valve pocket (10) is interior, valve completely closes, and motor (2) locks, when occurring that power-off etc. is urgent During fault, the latch-release of motor (2), owing to leading screw uses ball-screw, thus silk Thick stick will not self-locking, at this moment spring will promote wire lever (9) to move upward, thus open valve.

The most by way of example this utility model is illustrated, but this utility model is not limited to above-mentioned Specific embodiment, all any change or modification done based on this utility model belong to this utility model Claimed scope.
