Secondly, the operation process of the equipment is relatively complicated and requires professional technicians to operate and adjust it, which not only increases the difficulty of operation, but also increases human resource costs. These problems have affected the convenience and practicality of the equipment to a certain extent. Utility Model Content

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, the energy fracturing fluid injection flow control device includes a shell 1, the bottom of the shell 1 is fixedly connected to the bottom ring 2, the inside of the shell 1 is provided with an opening and closing mechanism 3, the opening and closing mechanism 3 includes a top cover 4, the bottom of the top cover 4 is fixedly connected to the shell 1, the inner side of the shell 1 is slidably connected to the gate 1 8, the middle part of the shell 1 is slidably connected to the gate 2 9, the top of the shell 1 is slidably connected to the gate 3 10, the inner sides of the gate 1 8, the gate 2 9 and the gate 3 10 are all fixedly connected with two threaded blocks 11, the inner sides of the threaded blocks 11 are all meshedly connected with screw rods 7, the tops of the screw rods 7 are all fixedly connected with driving wheels 12, and the tops of the three driving wheels 12 at the front of the shell 1 are respectively fixedly connected with three knobs 5.

[0023] In this embodiment, the inner side of the top cover 4 is fixedly connected to a limit block 13, the top of the limit block 13 is rotationally connected to a gear 14, the middle of the limit block 13 is rotationally connected to a gear 2 15, and the bottom of the limit block 13 is rotationally connected to a gear 3 16, and three pipes 6 are fixedly connected to one side of the outer shell 1.

[0024] The limiting block 13 can limit the positions of the gear 1 14 , the gear 2 15 and the gear 3 16 so that they can only rotate at the original position.

[0025] In this embodiment, two disc-shaped protrusions are provided in the middle of the limit block 13, and round holes are opened on the tops of the gear 1 14, the gear 2 15 and the gear 3 16, which penetrate to the bottom.

[0026] The limit block 13 separates the gear 1 14 from the gear 2 15 and the gear 3 16 through two disc-shaped protrusions so that they will not interfere with each other during movement.

[0027] In this embodiment, the inner diameter of the top of the housing 1 is larger than the inner diameter of the middle, and the inner diameter of the middle of the housing 1 is larger than the inner diameter of the bottom.

[0028] The housing 1 has three different inner diameters, so as to facilitate the movement of the internal components and avoid movement interference.

[0029] In this embodiment, the outer diameter of gate 1 8 matches the inner diameter of the bottom of the housing 1 , the outer diameter of gate 2 9 matches the inner diameter of the middle of the housing 1 , and the outer diameter of gate 3 10 matches the inner diameter of the top of the housing 1 .

[0030] Gate 1 8 , gate 2 9 and gate 3 10 are respectively fitted to the inner wall of the outer shell 1 at different positions, so as to control the opening and closing of different pipelines 6 .

[0031] In this embodiment, a cavity is formed on the inner side of the top cover 4 , six circular holes are formed on the bottom of the top cover 4 , and three circular holes are formed on the top of the top cover 4 .

[0032] The cavity of the top cover 4 can accommodate the driving wheel 12 to move inside, and the bottoms of the three knobs 5 respectively penetrate the three circular holes on the top of the top cover 4 to be connected with the corresponding driving wheels 12 .

[0033] In this embodiment, a screw hole is opened at the top of the threaded block 11 and penetrates to the bottom, and six screw rods 7 are evenly distributed on the inner side of the housing 1 in a ring shape.

[0034] The six screw rods 7 are grouped into two groups, which are divided into three groups in total. Each group is connected to two threaded blocks 11 on different gates. The rotation of the screw rods 7 can drive the threaded blocks 11 connected thereto to move.

[0035] It should be noted that the utility model is an energy fracturing fluid injection flow control device, which can simultaneously connect three pipelines 6 for output when in use, thereby improving output efficiency and adapting to different usage requirements, and can control the opening and closing of the three pipelines 6 and flow regulation respectively to achieve flow control;

[0036] The fracturing fluid enters the interior of the housing 1 through the bottom of the housing 1 and is discharged through different pipes 6. When the bottom pipe 6 is opened and closed, the specific implementation method is to rotate the knob 5 on one side of the top cover 4. When the knob 5 is rotated, the driving wheel 12 connected thereto will be driven to rotate together. When the driving wheel 12 rotates, the screw rod 7 and the gear 14 at the bottom will be driven to rotate. When the gear 14 rotates, another driving wheel 12 connected thereto and the screw rod 7 at the bottom thereof will be driven to rotate. After the two screw rods 7 rotate, the connected threaded block 11 can be driven to move under the action of the thread.

[0037] The threaded block 11 drives the gate 8 to move. Since the gate 8 is connected to the two screw rods 7 through the two threaded blocks 11 and is constrained by the two screw rods 7 and cannot rotate, it will move along the axis of the screw rod 7 after being driven by the thread. By turning the knob 5 in different directions, the moving direction of the gate 8 can be controlled. By moving the gate 8 downward to reach the maximum stroke, the bottom pipe 6 can be closed. When passing through, the gate 8 moves up and can block the bottom pipe 6 to different degrees, thereby controlling the flow. By moving the gate 8 upward to reach the maximum stroke, the pipe 6 can be completely released from the blockage.

[0038] And because the inner wall of the shell 1 has different inner diameters, and the three pipes 6 are respectively connected to positions with different inner diameters, the lifting and lowering of gate one 8 will not close other pipes 6. By turning other knobs 5 in the same way, the opening and closing of gate two 9 and gate three 10 can be controlled, and the opening and closing of the three gates are independent of each other and will not interfere with each other. Any gate can be opened or closed by different knobs 5, and can be adjusted according to specific usage requirements during use, thereby increasing the applicability of the equipment.

[0039] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
