The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] This utility model provides a fracturing head device for fracturing wellheads in oil extraction equipment, including an installation ring 101, a sealing shell 104, and a self-controlled diversion and speed control assembly. The self-controlled diversion and speed control assembly includes a main flow pipe 105, a diversion block 106, a sealing ring 107, a mounting hole 108, a connecting hole 109, a diversion pipe 110, a rotating ring 112, a flow control plate 113, a positioning hole 111, mounting teeth 102, and a mounting hole 103. This solution solves the problems of easy seal failure and insufficient connection stability in traditional fracturing head devices during long-term use, leading to reduced fracturing operation efficiency and even potential safety accidents. It is understood that the aforementioned solution allows the installation ring 101 to be installed in a designated position via the mounting teeth 102 and the mounting hole 103 during oil extraction and transmission. Then, the transmission pipeline is connected to the main flow pipe 105 and the diversion pipe 110 respectively. The 05 and transmission pipelines are connected by the mounting hole 108 and the connecting hole 109, while the diversion pipe 110 is connected to the transmission pipeline by the positioning hole 111. When transmitting oil, due to the presence of the diversion block 106, when the overall internal pressure is too high, the diversion block 106 will effectively divert the oil during the transmission process, reducing the pressure in the main pipe 105. The flow control plate 113 in the diversion pipe 110 will automatically rotate when the pressure is too high, thereby opening a wider orifice to facilitate the passage of oil. The rotating ring 112 will promptly reset the flow control plate 113 when the pressure decreases, thus forming a graded diversion transmission guarantee, greatly improving the overall safety. This effectively solves the problems of easy seal failure and insufficient connection stability in traditional fracturing head devices during long-term use, which lead to reduced fracturing operation efficiency and may even cause safety accidents.
[0022] In this specific embodiment, the sealing shell is fixedly connected to the mounting ring 101 and located above the mounting ring 101; the main flow pipe 105 is fixedly connected to the sealing shell 104 and located above the sealing shell 104; the sealing ring 107 is detachably connected to the main flow pipe 105 and located on the upper outer surface of the main flow pipe 105; the diverting block 106 is disposed inside the main flow pipe 105, and the outer surface of the diverting block 106 is rotatably connected to the sealing ring 107 and located inside the sealing ring 107; the mounting hole 108 is fixedly connected to the diverting block 106 and located at the inner center of the diverting block 106; the connecting... The connecting hole 109 is fixedly connected to the sealing shell 104 and is located inside the upper part of the sealing shell 104. When transporting oil, the mounting ring 101 is installed in the designated position through the mounting teeth 102 and the mounting hole 103. Then, the transmission pipeline is connected to the main pipe 105 and the branch pipe 110 respectively. The main pipe 105 and the transmission pipeline are connected by the placement hole 108 and the connecting hole 109. When transporting oil, due to the presence of the branch block 106, when the overall internal pressure is too high, the branch block 106 will effectively divert the oil during the transmission process and reduce the pressure in the main pipe 105.
[0023] The diversion pipe 110 is fixedly connected to the sealing shell 104 and is located diagonally above the sealing shell 104, and the diversion pipe 110 is disposed on one side of the main pipe 105.
[0024] Secondly, the rotating ring 112 is rotatably connected to the diversion pipe 110 and is located on the outer surface of the diversion pipe 110. The flow control plate 113 is disposed inside the diversion pipe 110, and the outer surface of the flow control plate 113 passes through the diversion pipe 110 and is detachably connected to the rotating ring 112, and is located on the inner side of the rotating ring 112. The flow control plate 113 in the diversion pipe 110 will automatically rotate when the pressure is too high, thereby opening a wider orifice to facilitate the passage of oil. The rotating ring 112 will promptly reset the flow control plate 113 when the pressure decreases, thereby forming a graded diversion transmission guarantee, which greatly improves the overall safety.
[0025] Meanwhile, the positioning hole 111 is fixedly connected to the diversion pipe 110 and is located inside the end of the diversion pipe 110 away from the sealing shell 104. The diversion pipe 110 will be connected to the transmission pipe through the positioning hole 111.
[0026] In addition, the mounting tooth 102 is fixedly connected to the mounting ring 101 and located below the mounting ring 101. The mounting hole 103 is fixedly connected to the mounting ring 101 and located inside the mounting ring 101. The mounting hole 103 is disposed on one side of the mounting tooth 102. The mounting tooth 102 and the mounting hole 103 will be auxiliary structural components to facilitate the mounting ring 101 to be installed in a designated position.
[0027] When using this invention for oil extraction and transportation, the mounting ring 101 is installed in a designated position via the mounting teeth 102 and the mounting hole 103. Then, the transmission pipeline is connected to the main flow pipe 105 and the branch pipe 110, respectively. The main flow pipe 105 and the transmission pipeline are connected by the placement hole 108 and the connection hole 109, while the branch pipe 110 is connected to the transmission pipeline by the positioning hole 111. When transporting oil, due to the presence of the branch block 106, when the overall internal pressure is too high, the branch block 106 will effectively control the transmission process. The oil in the main pipe 105 is diverted to reduce the pressure. The flow control plate 113 in the diversion pipe 110 will automatically rotate when the pressure is too high, thereby opening a wider orifice to facilitate the passage of oil. The rotating ring 112 will reset the flow control plate 113 in time when the pressure decreases. This forms a staged diversion transmission guarantee, which greatly improves the overall safety. This effectively solves the problems of easy seal failure and insufficient connection stability in traditional fracturing head devices during long-term use, which leads to reduced fracturing operation efficiency and may even cause safety accidents.
[0028] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
