[0002] In the field of fermentation and related industries, the control of material flow direction is crucial, which usually depends on the precise opening and flexible switching of valves in the pipeline system. At present, such operations are mainly achieved through pipeline valves and jumper plates operated manually.

[0003] In the related art, when manually operating the jumper plate and installing and switching the jumper pipe, the more commonly used is the fixed-type jumper pipe. During the production operation process, adjustable wrenches of different specifications are required to open and tighten the valves. However, the adjustable structure wrenches used in the existing technology have significant limitations in actual operation, which are specifically manifested in the following aspects:

[0004] 1. Poor tool versatility: Most of the existing adjustable structure wrenches are designed with a single specification and are only suitable for specific-sized unions. When facing valves of different diameters, operators need to frequently change tools, which greatly reduces work efficiency.

[0005] 2. Inconvenient operation under space constraints: In narrow or restricted spaces, such as inside a fermenter or a densely piped area, the shape and size of traditional wrenches may not provide enough operating space, resulting in increased operation difficulty and even the inability to complete tasks.

[0006] 3. Limited torque transmission: In some cases, especially in applications that require a large torque, the existing tools may not be able to effectively transmit the required force due to design or material reasons, thus affecting the stability and safety of the operation.

[0007] 4. High tool vulnerability: Due to limitations in material and design, traditional adjustable structure wrenches are prone to problems such as wear and deformation after long-term use, affecting the durability and service life of the tools and increasing maintenance costs.

[0008] Therefore, the adjustable structure wrenches and operation methods in the existing technology have obvious deficiencies in terms of flexibility, efficiency, application range, and durability. There is an urgent need for a new type of tool that can overcome the above problems, improve the disassembly and assembly efficiency of valves and pipe connectors, simplify the operation process, enhance operation safety, and ultimately optimize the production process and save costs.

[0040] In the field of fermentation and related industries, the control of material flow is crucial, which usually relies on the precise opening and closing and flexible switching of valves in the pipeline system. Currently, such operations are mainly achieved through pipeline valves and manually operated jumper plates.

[0041] In the related technologies, when manually operating the installation and switching of the jumper plate and the jumper pipeline, the more commonly used is the fixed-type jumper pipe. During the production operation process, adjustable wrenches of different specifications are required to open and tighten the valves. However, the adjustable wrenches used in the existing technologies have significant limitations in actual operation, which are specifically manifested in the following aspects:

[0042] 1. Poor tool versatility: Most of the existing adjustable wrenches are designed with a single specification and are only applicable to union nuts of specific sizes. When facing valves of different diameters, operators need to frequently change tools, which greatly reduces the work efficiency.

[0043] 2. Inconvenient operation under space constraints: In narrow or restricted spaces, such as inside a fermenter or in a densely piped area, the shape and size of traditional wrenches may not provide enough operating space, resulting in increased operation difficulty and even inability to complete the task.

[0044] 3. Limited torque transmission: In some cases, especially in applications that require a large torque, the existing tools may not be able to effectively transmit the required force due to design or material reasons, thus affecting the stability and safety of the operation.

[0045] 4. High tool vulnerability: Due to limitations in material and design, traditional adjustable wrenches are prone to problems such as wear and deformation after long-term use, which affects the durability and service life of the tools and increases the maintenance cost.

[0046] Therefore, the adjustable wrenches and operation methods in the existing technologies have obvious deficiencies in terms of flexibility, efficiency, application range, and durability. There is an urgent need for a new type of tool that can overcome the above problems, improve the disassembly and assembly efficiency of valves and pipeline connectors, simplify the operation process, enhance operation safety, and ultimately optimize the production process and save costs.

[0047] For this reason, as Figure 1 and Figure 2As shown in the figure, the hook-type quick-disassembly wrench proposed by the present utility model includes a holding portion 100, a first curved arc portion 200 integrally fixed to one end of the holding portion 100, and a second curved arc portion 300 integrally fixed to the other end of the holding portion 100. Among them, both the first curved arc portion 200 and the second curved arc portion 300 are crescent-shaped. Specifically, the first curved arc portion 200 and the second curved arc portion 300 are adapted to abut against and position the circumferential wall of the round nut 410. The sizes of the first curved arc portion 200 and the second curved arc portion 300 are different to respectively position round nuts 410 with different specifications. Further, a first pointed hook head 210 is provided at the end of the first curved arc portion 200, and a second pointed hook head 310 is provided at the end of the second curved arc portion 300. The first pointed hook head 210 and the second pointed hook head 310 are adapted to be clamped into the card slot 4101 of the round nut 410 and twist the round nut 410. It should be noted that through the unique double-headed crescent design, the operator can quickly switch to the wrench head suitable for round nuts 410 of different specifications, avoiding the time and labor costs in the replacement process of traditional tools. Among them, the different sizes of the first curved arc portion 200 and the second curved arc portion 300 ensure the effective tightening and disassembly of round nuts 410 of different sizes, while the pointed hook heads can accurately fit into the card slot 4101 of the round nut 410. Whether it is a rectangular or circular card slot 4101, a stable grasping force can be provided, thus ensuring the accuracy and efficiency of the operation. It is especially suitable for the busy operation environment at the fermentation site, greatly improving the production efficiency and the working experience of the operator.

[0048] It is easy to understand that the card slot of the round nut includes a circular card slot and a rectangular card slot. The wrench can adapt to valves and pipe systems with different design standards, expanding the scope of application of the tool, reducing the troubles of the operator when facing components with different standards, and enhancing the versatility and value of the tool.

[0049] Specifically, as Figure 1 shown, the round nut 410 is arranged on the union 400 and is used to fasten the union 400. The second curved arc portion 300 and the second pointed hook head 310 cooperate to be adapted to twist the union 400 with a specification of DN25 - DN50, ensuring efficient operation and precise matching in the connection of common medium and small-sized pipes, reducing operation errors caused by improper tool size, and improving the disassembly and assembly speed. In addition, the outer shape of the first curved arc portion 200 is larger than that of the second curved arc portion 300. The first curved arc portion 200 and the first pointed hook head 210 cooperate to be adapted to twist the union 400 with a specification of DN65 - DN100. It comprehensively covers valves of larger sizes, meets the requirements for the flexibility and versatility of tools in large pipe systems, reduces tool inventory, simplifies the tool selection of operators, and improves the overall operation efficiency. Furthermore, the wrench can be suitable for the disassembly and assembly of various material union pipe heads with specifications of DN25 - DN100.

[0050] Refer to Figure 2 In some embodiments of the utility model, the first pointed hook head 210 and the second pointed hook head 310 are both bent inward, which optimizes the contact angle between the wrench and the round nut 410, ensures that effective torque can be applied even in a confined space, and reduces the risk of tool slippage during operation. In addition, the first pointed hook head 210 and the second pointed hook head 310 that bend inward can prevent accidental injury to the operator, thereby enhancing the safety and reliability of operation. In some embodiments, the first pointed hook head 210 and the second pointed hook head 310 both have a thickened structure, which can prevent unhooking, further improving the safety and reliability of operation. In addition, the thicker first pointed hook head 210 and the second pointed hook head 310 provide additional strength and durability, which can maintain the performance and life of the wrench even under high-intensity use conditions, reduce downtime caused by tool damage, and reduce long-term maintenance costs. Specifically, Figure 3 As shown, the thickness of the first pointed hook head 210 and the second pointed hook head 310 are both greater than the thickness of the holding portion 100, which strengthens the mechanical strength of key parts, making it less likely to be deformed or damaged when subjected to high torque operations, extending the service life of the wrench and improving the safety of operation.

[0051] In some embodiments of the present invention, the grip portion 100 has a rigid reinforced structure, which enhances the overall stability of the wrench, maintains a good sense of control even under high torque operation, reduces the operator's physical exertion during use, and improves operating comfort and efficiency. Figure 2 The opposite side walls of the holding portion 100 are provided with concave grooves 101, which are reinforced by the concave grooves to prevent deformation. It also has the effect of improving the gripping feeling of the holding portion 100. Even when the hands are wet or wearing gloves, it can provide a good grip to prevent the tool from slipping, thereby improving the safety and reliability of the operation.

[0052] Optionally, the holding portion 100, the first curved portion 200 and the second curved portion 300 are integrally formed stainless steel parts, or are made of stainless steel with a hardness of SUS304 or above, which not only ensures the structural strength and corrosion resistance of the wrench, but also simplifies the manufacturing process and reduces production costs. At the same time, the selection of stainless steel materials improves the cleanliness of the wrench and meets the strict requirements of the fermentation industry on sanitary conditions.

[0053] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
