Description

Technical Field

[0001] The utility model relates to the technical field of valves, and more specifically, to a regulating valve for oil extraction. Background Art

[0002] A regulating valve, also known as a control valve, is the final control element in the field of industrial automation process control. It changes process parameters such as medium flow, pressure, temperature, and liquid level by receiving a control signal output from a regulating control unit and relying on power operation. Generally, it consists of an actuator and a valve. According to the stroke characteristics, regulating valves can be divided into linear stroke and angular stroke; according to the power used by the actuator, they can be divided into pneumatic regulating valves, electric regulating valves, and hydraulic regulating valves; according to their functions and characteristics, they can be divided into linear characteristics, equal percentage characteristics, and parabolic characteristics. Regulating valves are suitable for media such as air, water, steam, various corrosive media, mud, and oil products. Common classifications of regulating valves: pneumatic regulating valves, electric regulating valves, hydraulic regulating valves, and self-operated regulating valves.

[0003] Currently, the regulating valves used in existing oil extraction and transportation are inconvenient to operate, and they only have one adjustment method. When a malfunction occurs, the entire valve needs to be repaired and replaced, resulting in poor practicability. Therefore, a regulating valve for oil extraction is needed to solve this problem.

Flange plates are fixedly installed on the inlet and the outlet. A top cover is installed on the top of the valve body. A valve core is arranged inside the valve body. The protruding part at the bottom of the valve core is inserted into the limiting component at the bottom. A valve seat is opened inside the valve core. A valve flap that fits tightly with the valve seat is installed inside the valve seat. The valve core is located in the valve cavity. A connecting rod is fixedly installed at the top of the valve core. A handle is installed at the top of the connecting rod.

[0006] As a preferred technical solution of the utility model, the limiting component is provided with extrusion blocks and is symmetrically distributed.

Flanges 4 are fixedly installed on both the inlet 2 and the outlet 3. A top cover 5 is installed at the top of the valve body 1. A valve core 15 is arranged inside the valve body 1. The protruding part at the bottom end of the valve core 15 is inserted into the limiting component at the bottom end. A valve seat 14 is provided inside the valve core 15. A valve flap 13 that fits tightly with the valve seat 14 is installed inside the valve seat 14. The valve core 15 is located inside the valve cavity 16. A connecting rod 10 is fixedly installed at the top end of the valve core 15. A handle 9 is installed at the top end of the connecting rod 10. A sealing ring 17 is arranged inside the valve cavity 16. The sealing ring 17 is made of rubber material. The top end of the valve flap 13 is connected by a rotating rod 12. A rotating head 11 is fixedly installed at the top end of the rotating rod 12. A plurality of groups of bolts 6 are arranged between the valve body 1 and the top cover 5 and are distributed in a circle. The top cover 5 is connected to the valve body 1 through the bolts 6. A fixing part 7 is fixedly installed on the top cover 5. A fixing column 8 is fixedly installed on the fixing part 7. The connecting rod 10 passes through the fixing column 8 and is connected to the valve core 15 at the bottom end;

[0022] In this implementation mode, the rotating head 11 is set to rotate the valve core 15 at the bottom end of the rotating rod 12 to rotate inside the valve seat 14. When the valve core 15 is unfolded, the closing of the valve body 1 can be realized. Pulling the handle 9 to separate the valve core 15 from the valve cavity 16 can realize that the inlet 2 and the outlet 3 of the valve body 1 are completely in a communicating state. The whole technical solution realizes the opening and closing of the valve through two different methods. Embodiment

[0023] Refer to Figures 2 to 3 Describe Embodiment 2. This implementation mode further describes Embodiment 1, including a limiting component. Extrusion blocks 18 are provided on the limiting component and are symmetrically distributed. An extrusion rod 21 is fixedly installed on one side of the extrusion block 18. One side of the extrusion rod 21 is located inside the fixing block 22. A spring 23 is arranged between the extrusion rod 21 and the fixing block 22. Grooves 19 are opened between the extrusion blocks 18. A stop bar 20 connected by sliding is arranged inside the grooves 19;

[0024] In this embodiment, the extrusion block 18 on the limit component can be squeezed to both sides. The extrusion block 18 moves to both sides under the action of the spring 23, so that the groove on the extrusion block 18 is inserted and limited with the convex part at the bottom end of the valve core 15, ensuring the sealing performance of the entire valve body 1.

[0025] In specific applications, a valve core 15 is provided in the valve body 1 of the regulating valve set in this device. The valve core 15 is connected to the handle 9 through a connecting rod 10. By pulling the handle 9, the valve core 15 can be separated from the valve cavity 16, so that the inlet 2 and the outlet 3 of the valve body 1 are completely in a communicating state. The convex part at the bottom end of the valve core 15 is closely attached to the groove on the extrusion block 18 of the limit component at the bottom end. The extrusion block 18 can be squeezed to both sides. The extrusion block 18 moves to both sides under the action of the spring 23, so that the groove on the extrusion block 18 is inserted and limited with the convex part at the bottom end of the valve core 15, ensuring the sealing performance of the entire valve body 1, and facilitating the flow of oil. If the valve core 15 at the bottom end of the handle fails to be pulled, the rotary head 11 can be manually rotated to make the valve core 15 at the bottom end of the rotating rod 12 rotate in the valve seat 14, similar to the principle of a butterfly valve. When the valve core 15 is unfolded, the valve body 1 can be closed, and vice versa, the inlet 2 and the outlet 3 can be in a communicating state. The entire technical solution realizes the opening and closing of the valve in two different ways, ensuring the diversity adjustment of the valve body 1 and improving the practicability of the valve body 1.
