Technical Field

[0001] This utility model relates to the field of oil transportation technology, specifically to a controllable regulating valve for oil transportation. Background Technology

[0002] Petroleum is a viscous, dark brown liquid, mainly composed of a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. Controllable regulating valves for petroleum transportation are valves specifically designed for petroleum and liquid transportation systems, and are key equipment to ensure the efficient and safe operation of petroleum transportation systems.

[0003] The two ends of the controllable regulating valve used for oil transportation are usually connected by flanges. However, the flanges used in the existing regulating valves are misaligned with the flange holes in the pipeline, making it impossible for the regulating valve to be connected to the pipeline flange for installation, resulting in poor installation adaptability of the regulating valve. Utility Model Content

[0004] The purpose of this utility model is to provide a controllable regulating valve for oil transportation, so as to solve the problem mentioned in the background art that the flange used in the existing regulating valves is misaligned and mismatched with the flange holes in the pipeline, which makes it impossible for the regulating valve to complete the flange connection and installation with the pipeline, resulting in poor installation adaptability of the regulating valve.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a controllable regulating valve for oil transportation, comprising a valve body, a valve cover fixedly connected to the surface of the valve body, a valve stem rotatably connected to the surface of the valve cover, a rotating wheel fixedly connected to the surface of the valve stem, an assembly mechanism provided on the surface of the valve body, the assembly mechanism including a limiting ring, the limiting ring fixedly connected to the surface of the valve body, a first fixing ring fixedly connected to the surface of the valve body, a flange ring threadedly connected to the surface of the valve body, an external thread on the surface of the valve body, an internal thread on the inner ring of the flange ring, a limiting rod fixedly connected to the surface of the flange ring, and a limiting bolt threadedly connected to the surface of the limiting rod.

[0006] Preferably, the valve cover surface is provided with a limiting mechanism, the limiting mechanism including a second fixing ring, the second fixing ring being fixedly connected to the surface of the valve cover, a connecting rod being fixedly connected to the surface of the valve stem, a spring being fixedly connected to the surface of the connecting rod, an operating rod being fixedly connected to the surface of the spring, and a movable rod being fixedly connected to the surface of the operating rod, the movable rod being slidably connected to the surface of the connecting rod.

[0007] Preferably, the flange ring is threaded onto the surface of the external thread via external and internal threads, and the limiting ring restricts the threaded connection position of the flange ring on the valve body.

[0008] Preferably, the limiting rod has a threaded hole on its surface, and the limiting bolt is threadedly connected to the threaded hole of the limiting rod, and the limiting bolt moves up and down through the threaded hole of the limiting rod.

[0009] Preferably, the surface of the first fixing ring has multiple sets of limiting grooves, and the multiple sets of limiting grooves are evenly distributed in a circle on the outer side of the first fixing ring, and the limiting bolts are inserted into the limiting grooves of the first fixing ring.

[0010] Preferably, the spring force is applied to the movable rod through the operating rod, and a guide hole is provided on the surface of the connecting rod, and the movable rod slides on the guide hole of the connecting rod.

[0011] Preferably, multiple sets of limiting grooves are formed on the surface of the second fixed ring, and the limiting grooves are evenly distributed in a circular shape on the surface of the second fixed ring, and the movable rod is inserted into the limiting groove of the second fixed ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This control valve uses external and internal threads to thread flange rings to both ends of the valve body. The flange rings are rotated until they contact the limiting rings. The position of the limiting rod is adjusted so that the threaded hole of the limiting rod aligns with the limiting groove of the first fixed ring. The limiting bolt is then rotated into the threaded hole of the limiting rod, causing it to insert into the limiting groove of the first fixed ring. The first fixed ring, through the limiting rod and the limiting bolt, restricts the position of the flange rings at both ends of the valve body. Furthermore, the flange rings and the valve body are sealed by a threaded connection. By assembling flange rings identical to those used in pipeline flanges, flange installation of the control valve is achieved, avoiding the difficulty of installing the control valve and improving its installation adaptability.

[0014] 2. In this regulating valve, the rotating valve stem is driven to rotate synchronously by the rotating wheel, which in turn drives the movable rod to rotate synchronously. The spring force acts on the movable rod through the operating rod, causing the movable rod to slide downward on the guide hole of the connecting rod until it is inserted into the limiting groove of the second fixed ring. The second fixed ring restricts the valve stem from continuing to rotate through the connecting rod and the movable rod, ensuring the stability of the valve stem and thus ensuring the stability of the regulating valve.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A controllable regulating valve for oil transportation includes a valve body 1, a valve cover 11 fixedly connected to the surface of the valve body 1, a valve stem 12 rotatably connected to the surface of the valve cover 11, and a rotary wheel 13 fixedly connected to the surface of the valve stem 12. During rotation, the valve stem 12 can adjust the opening size between the valve core and the valve seat, thereby controlling the flow rate of oil transportation. An assembly mechanism is provided on the surface of the valve body 1, including a limiting ring 2 fixedly connected to the surface of the valve body 1. A first fixing ring 21 is fixedly connected to the surface of the valve body 1. A flange ring 22 is threaded onto the surface of valve body 1. An external thread 23 is formed on the surface of valve body 1. An internal thread 24 is formed on the inner ring of flange ring 22. A limit rod 25 is fixedly connected to the surface of flange ring 22. A limit bolt 26 is threaded onto the surface of limit rod 25. This assembly mechanism can assemble flange ring 22 to both ends of valve body 1, so that flange ring 22 assembled to both ends of valve body 1 can adapt to the flange at the pipeline end, thereby enabling the control valve to be flange-connected to the pipeline, improving the installation adaptability of the control valve.

[0024] Furthermore, a limiting mechanism is provided on the surface of the valve cover 11. The limiting mechanism includes a second fixing ring 3, which is fixedly connected to the surface of the valve cover 11. A connecting rod 31 is fixedly connected to the surface of the valve stem 12. A spring 32 is fixedly connected to the surface of the connecting rod 31. An operating rod 33 is fixedly connected to the surface of the spring 32. A movable rod 34 is fixedly connected to the surface of the operating rod 33. The movable rod 34 is slidably connected to the surface of the connecting rod 31. After the valve stem 12 has rotated, in order to prevent the valve stem 12 from rotating accidentally and to improve the stability of the entire regulating valve, the limiting mechanism can limit the state of the valve stem 12, thereby preventing the valve stem 12 from continuing to rotate.

[0025] Furthermore, the flange ring 22 is threaded onto the surface of the external thread 23 via the external thread 23 and the internal thread 24. The limiting ring 2 restricts the threaded connection position of the flange ring 22 on the valve body 1, so that the flange ring 22 is located at both ends of the valve body 1 after rotation. The flange ring 22 has flange holes corresponding to the pipe flange on its surface, so that the valve body 1 can be flanged through the flange ring 22.

[0026] Furthermore, the limit rod 25 has a threaded hole on its surface, and the limit bolt 26 is threaded into the threaded hole of the limit rod 25. The limit bolt 26 moves up and down through the threaded hole of the limit rod 25. The limit rod 25 rotates on the valve body 1 along with the flange ring 22. After the limit rod 25 is set, the position of the limit rod 25 is finely adjusted so that the threaded hole of the limit rod 25 is aligned with the limit groove of the first fixing ring 21, and then the height of the limit bolt 26 is raised or lowered.

[0027] Furthermore, multiple sets of limiting grooves are formed on the surface of the first fixing ring 21, and the multiple sets of limiting grooves are evenly distributed in a circular shape on the outer surface of the first fixing ring 21. The limiting bolt 26 is inserted into the limiting groove of the first fixing ring 21. The first fixing ring 21 restricts the flange ring 22 from rotating on the valve body 1 through the internal thread 24 and the limiting rod 25, thereby ensuring the position of the flange ring 22 on the valve body 1, and thus ensuring the connection strength between the flange ring 22 and the pipeline flange.

[0028] Furthermore, the elastic force of the spring 32 acts on the movable rod 34 through the operating rod 33. A guide hole is provided on the surface of the connecting rod 31. The movable rod 34 slides on the guide hole of the connecting rod 31. During the rotation of the valve stem 12, the connecting rod 31 is driven to rotate. During the rotation of the connecting rod 31, the movable rod 34 is driven to rotate synchronously, thereby changing the position of the movable rod 34 at the top of the second fixed ring 3.

[0029] Furthermore, multiple sets of limiting grooves are formed on the surface of the second fixed ring 3, and the limiting grooves are evenly distributed in a circular shape on the surface of the second fixed ring 3. The movable rod 34 is inserted into the limiting groove of the second fixed ring 3. The second fixed ring 3 restricts the valve stem 12 from continuing to rotate through the movable rod 34 and the second fixed ring 3, thereby avoiding accidental rotation of the valve stem 12 after rotation is completed and ensuring the stability of the valve stem 12.

[0030] Working principle: The flange ring 22 is threaded to both ends of the valve body 1 through the external thread 23 and the internal thread 24. The flange ring 22 is rotated until it contacts the limiting ring 2. The position of the limiting rod 25 is adjusted so that the threaded hole of the limiting rod 25 is aligned with the limiting groove of the first fixing ring 21. The limiting bolt 26 is rotated on the threaded hole of the limiting rod 25 so that the limiting bolt 26 is inserted into the limiting groove of the first fixing ring 21. The first fixing ring 21 restricts the position of the flange ring 22 at both ends of the valve body 1 through the limiting rod 25 and the limiting bolt 26. The flange ring 22 and the valve body 1 are sealed by a threaded connection. By assembling the flange ring 22 which is the same as the pipe flange, the flange installation of the control valve can be realized, avoiding the difficulty of installing the control valve and improving the installation adaptability of the control valve.

[0031] As the valve stem 12 rotates via the rotating wheel 13, the connecting rod 31 rotates synchronously. The connecting rod 31 then drives the movable rod 34 to rotate synchronously. The elastic force of the spring 32 acts on the movable rod 34 through the operating rod 33, causing the movable rod 34 to slide downwards in the guide hole of the connecting rod 31 until it is inserted into the limiting groove of the second fixed ring 3. The second fixed ring 3 restricts the valve stem 12 from continuing to rotate through the connecting rod 31 and the movable rod 34, ensuring the stability of the valve stem 12 and thus ensuring the stability of the regulating valve.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
