Description

Technical Field

[0001] The utility model relates to the technical field of fracturing valves, and particularly relates to a fracturing valve for oil wells. Background Technique

[0002] Fracturing exploitation is a process technology used to increase the production of oil wells or gas wells during underground oil or gas extraction. It mainly uses pressurizing equipment to inject high-speed fluids into the wellbore, thereby playing the role of fracturing the formation and maintaining the fractured state of the formation. During the process of injecting high-speed fluids using pipelines, various gate valves are inevitably used. However, traditional gate valves are inconvenient to operate and often require manual control or electric control. Manual control cannot achieve rapid operation, consuming a certain amount of operation time and being unfavorable for making timely actions. Electric control is not conducive to inspection, and once the electric control fails, serious consequences are very likely to occur, highlighting the deficiencies of traditional fracturing valves.

[0003] However, when the existing fracturing valves are in use, there are still certain problems:

[0004] Under the existing technology, when the fracturing valve is in use, the sealing ring at its connection is often an integral circular structure. During assembly, there are easily gaps at its end face, and the connection part is directly exposed to the outside without protection. When subjected to external force impact, the connection part is relatively fragile and easily deformed and damaged.

[0005] In view of the above problems, an innovative design is carried out on the basis of the original fracturing valve. Content of the Utility Model
