Description

Technical Field

[0001] The utility model relates to the technical field of kill manifolds, in particular to a high sulfur-resistant throttling kill manifold. Background Art

[0002] A kill manifold is a term used in oil exploitation. The function of the kill manifold is as follows: when the wellhead is sealed with a full-closed ram preventer, mud is forcibly filled through the kill manifold to implement the kill operation; when a blowout occurs, clear water is forcibly injected into the wellhead through the kill manifold to prevent combustion; when the well has caught fire during a blowout, a fire extinguishing agent is forcibly injected into the wellbore through the kill manifold to assist in extinguishing the fire. In the prior art, there is already a throttling kill manifold in use. The throttling kill manifold is equipped with a throttle valve or a throttle valve group. The function of the throttle valve is to adjust the flow rate, generate throttling pressure, and keep the bottom hole pressure constant.

[0003] The current high sulfur-resistant throttling kill manifold is usually composed of a base, a bracket, a throttling manifold, and a kill manifold. When in use, the manifold needs to be connected to a four-way gate valve. Since the height of the connection end of the throttling kill manifold is fixed, it is easy to have a height difference between it and the four-way gate valve, resulting in a reduction in the sealing performance between them. Summary of the Utility Model

[0004] The utility model provides a high sulfur-resistant throttling kill manifold. Through the provided auxiliary component, positions such as the mounting plate can be adjusted, thereby adjusting the height of the base and the throttling kill manifold at the top of the base, so as to make the height of the throttling kill manifold consistent with that of the four-way gate valve, facilitating their connection, and avoiding a height difference between them, which affects the sealing performance of their connection. In summary, the problems in the background art are solved.

[0005] In order to achieve the above object, the utility model adopts the following technical scheme:

[0006] A high sulfur-resistant throttling kill manifold, comprising a frame arranged at the top of a base, and a throttling kill manifold body composed of a throttling manifold and a kill manifold arranged on the surfaces of the frame and the base. An auxiliary component is arranged on the surface of the base;

[0007] The inside of the auxiliary component includes a groove arranged at the bottom end of the base, and a mounting plate is slidably arranged inside the groove. A threaded rod for moving the mounting plate is threadedly connected to the top of the base;

[0008] A screw rod is rotatably connected inside the mounting plate, and moving blocks are respectively threadedly connected to both sides of the surface of the screw rod. The top end of the moving block is connected to a support bar through a movable shaft, and the other end of the support bar is connected to a fixing plate through a movable shaft. A pulley is connected to the surface of the fixing plate.

[0009] As a further description of the above technical solution:

[0010] The threads on both sides of the screw rod surface are arranged in the opposite direction, and the moving block is slidably connected to the inside of the mounting plate.

[0011] As a further description of the above technical solution:

[0012] The threaded rod passes through the base and is rotatably connected to the top end of the mounting plate.

[0013] As a further description of the above technical solution:

[0014] The inside of the auxiliary component further includes an annular plate sleeved on the surface of the threaded rod, and a rack is connected to the inner wall of the annular plate. The surface of the rack is meshed with a gear, and a fixing rod threadedly connected to the mounting plate is connected to the surface of the gear.

[0015] As a further description of the above technical solution:

[0016] A chute is opened inside the annular plate, and a slider rotatably connected to the fixing rod is slidably connected to the inside of the chute.

[0017] As a further description of the above technical solution:

[0018] The pipe valve on the surface of the throttle kill manifold body is a high sulfur-resistant valve.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are:

[0020] In the present utility model, through the arranged auxiliary component, the positions such as the mounting plate can be adjusted, so as to adjust the height of the base and the throttle kill manifold on the top of the base, so as to make the height between the throttle kill manifold and the four-way gate valve consistent, which is convenient for their connection and avoids the height difference between them, affecting the connection tightness.

[0021] In the present utility model, by rotating the screw rod inside the mounting plate, the moving blocks on both sides of it can drive the support bars to move, so that the fixing plate and the pulley connected to one end of the support bar can be moved out of the inside of the mounting plate, so as to finely adjust the positions of the base and the throttle kill manifold body through the pulley, which is convenient for connection.

[0022] In the present utility model, by rotating the annular plate inside the auxiliary component, the fixing rod inside it can rotate and move inside the base, and the fixing rod can move to the surface of the mounting plate and be threadedly connected to it, so as to support the mounting plate, avoiding that the weight of the base and the throttle kill manifold body is too heavy, resulting in the thread between the threaded rod and the base being unable to support it.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0030] Refer to Figures 1 - 4, a high sulfur-resistant throttle and kill manifold, comprising a frame 2 arranged at the top end of a base 1, and a throttle and kill manifold body 3 composed of a throttle manifold and a kill manifold arranged on the surfaces of the frame 2 and the base 1. An auxiliary component is arranged on the surface of the base 1; the inside of the auxiliary component includes a groove 4 arranged at the bottom end of the base 1, and a mounting plate 5 is slidably arranged inside the groove 4. A threaded rod 6 for moving the mounting plate 5 is threadedly connected to the top end of the base 1; a screw rod 7 is rotatably connected inside the mounting plate 5, and moving blocks 8 are respectively threadedly connected to both sides of the surface of the screw rod 7. The top end of the moving block 8 is connected to a support bar 9 through a movable shaft, and the other end of the support bar 9 is connected to a fixing plate 10 through a movable shaft. A pulley 11 is connected to the surface of the fixing plate 10. When it is necessary to adjust the height of the base 1 and the throttle and kill manifold body 3, the threaded rod 6 can be rotated to drive the mounting plate 5 rotatably connected to its bottom end to move, so as to adjust the height of the base 1 and the throttle and kill manifold body 3 through the mounting plate 5, which is convenient for connecting the throttle and kill manifold body 3 with a four-way gate valve. After the adjustment is completed, the annular plate 12 can be rotated so that the fixing rod 15 inside it can pass through the base 1 and be threadedly connected to the top end of the mounting plate 5, so as to support the mounting plate 5. If it is necessary to adjust positions such as the base 1, the screw rod 7 can be rotated to drive the moving blocks 8 on both sides inside it to drive the support bar 9 to move, so that the fixing plate 10 and the pulley 11 connected to the top end of the support bar 9 can be moved out, so as to move positions such as the base 1 and the throttle and kill manifold body 3 through the pulley 11, which is convenient for connection.

[0031] Further, the threads on both sides of the surface of the screw rod 7 are arranged in the opposite direction, and the moving block 8 is slidably connected to the inside of the mounting plate 5. This is to facilitate the limited movement of the moving block 8 inside the mounting plate 5 when the screw rod 7 rotates. Of course, the moving blocks 8 on both sides of the screw rod 7 move towards each other or away from each other simultaneously.

[0032] Further, the threaded rod 6 passes through the base 1 and is rotatably connected to the top end of the mounting plate 5. This is to facilitate the rotation of the threaded rod 6 when it rotates and moves, and it can rotate on the top end of the mounting plate 5 and drive the mounting plate 5 to move, so as to adjust the height between the base 1 and the throttle and kill manifold body 3.

[0033] Further, the interior of the auxiliary component further includes an annular plate 12 sleeved on the surface of the threaded rod 6. The inner wall of the annular plate 12 is connected with a rack 13. The surface of the rack 13 is meshed and connected with a gear 14. The surface of the gear 14 is connected with a fixing rod 15 that is threadedly connected to the mounting plate 5. The fixing rod 15 is threadedly connected to the base 1. When the annular plate 12 rotates through the slider 17 and the chute 16, the rack 13 on its surface can move on the surface of the gear 14, so that the gear 14 drives the fixing rod 15 to rotate on the surface of the slider 17. Since the fixing rod 15 is threadedly connected to the base 1, the fixing rod 15 can rotate and move, so that the fixing rod 15 can be moved to the surface of the mounting plate 5 and threadedly connected therewith, which can improve the support for the mounting plate 5. The top of the mounting plate 5 is annularly and equidistantly provided with a plurality of threaded holes for facilitating threaded connection with the fixing rod 15.

[0034] Further, a chute 16 is formed inside the annular plate 12, and a slider 17 that is rotatably connected to the fixing rod 15 is slidably connected inside the chute 16. The annular plate 12 can move on the surface of the slider 17 through the chute 16. When the fixing rod 15 rotates and moves, it can rotate on the surface of the slider 17 and drive the slider 17, the chute 16, the annular plate 12, etc. to move.

[0035] Further, the pipe valve parts on the surface of the throttle kill manifold body 3 are high sulfur-resistant valve parts. The high sulfur-resistant valve parts have good sulfur resistance and strong erosion resistance, which improves the service life of the throttle kill manifold.

[0036] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
