Description

Technical Field

[0001] This application relates to the field of valve wrench technology, and in particular to explosion-proof wrenches for carbon fiber square ball valves. Background Technology

[0002] A valve wrench is a tool used in pipeline systems to control the opening and closing of valves. It mainly uses the lever principle to apply force to control the flow rate, pressure, and flow direction of fluid media.

[0003] However, most existing valve wrenches are made of all-metal material. Due to the high density of metal, the wrenches are heavy and inconvenient to carry and use. During long-term operation, such as frequently opening or closing valves, the operator's arm may become fatigued, reducing work efficiency. Utility Model Content

[0004] The purpose of this application is to provide a carbon fiber square ball valve explosion-proof wrench, which has the advantages of being easy to carry and use. It solves the problem that most existing valve wrenches are made of all-metal materials. Due to the high density of metal materials, the overall weight of the wrench is large, which makes it inconvenient to carry and use. During long-term operation, such as frequent opening or closing of valves, it is easy to cause arm fatigue of the operator and reduce work efficiency.

[0005] The explosion-proof wrench for carbon fiber square ball valves provided in this application adopts the following technical solution: The explosion-proof wrench for carbon fiber square ball valves includes a carbon fiber collar and a copper component. A key block is fixedly connected to one side of the inner wall of the carbon fiber collar, and an installation groove is fixedly connected to one side of the outer wall of the copper component. A reinforcing block is fixedly connected to one side of the outer wall of the carbon fiber collar. Two reinforcing strips arranged in a mirror image are fixedly connected to the end of the reinforcing block away from the carbon fiber collar. A carbon fiber handle is fixedly connected to the outer wall of the carbon fiber collar, and a hollow groove is opened on one side of the inner side of the carbon fiber handle.

[0006] By adopting the above technical solution, the installation groove on the inner wall of the carbon fiber collar and the key block on the outer wall of the copper part cooperate with each other. The hollow groove, reinforcing block, and reinforcing strip inside the carbon fiber handle improve the wrench's stability and structural strength while reducing the weight of the main body and minimizing operator fatigue. The copper part is embedded in the installation groove of the carbon fiber collar through the key block, forming a stable connection that ensures no relative slippage when turning valves, guaranteeing precise force application. The reinforcing block and reinforcing strip enhance the connection strength between the carbon fiber collar and the carbon fiber handle, preventing the handle from breaking under excessive force. The hollow groove inside the carbon fiber handle reduces the overall weight through a perforated structure while maintaining the handle's structural strength. This device, through the inclusion of the carbon fiber sleeve, reinforcing block, and reinforcing strip, reduces the overall weight of the wrench, making it more portable and easier to use.

[0007] Preferably, the cavity is filled with expanding foam.

[0008] By adopting the above technical solution, the hollow groove inside the handle provides a filling space for the expanding foam. The expanding foam is filled into the hollow groove, and the expansion effect of the expanding foam after curing provides internal support for the carbon fiber handle, making the handle easier to form during molding and ensuring that the molded handle can be more rounded, thus improving the comfort of use.

[0009] Preferably, the outer wall of the copper part is knurled.

[0010] By adopting the above technical solution, the knurling on the outer wall of the copper part increases the contact area between the copper part and the carbon fiber sleeve when bonding the copper part and the carbon fiber sleeve, ensuring the stability of the connection, enabling it to resist torsional forces, and preventing relative movement or detachment between the copper part and the carbon fiber sleeve.

[0011] Preferably, the copper component is fixedly disposed inside the carbon fiber collar, and the key block is fixedly disposed inside the mounting groove.

[0012] By adopting the above technical solution, the copper part is fixed inside the carbon fiber collar, and the key block on the inner wall of the carbon fiber collar is embedded in the corresponding mounting groove on the outer wall of the carbon fiber collar. The interlocking structure forms a stable connection. When the torque is applied to the valve with a wrench, the key block and the mounting groove are tightly engaged, which can stably transmit the force from the carbon fiber collar to the copper part, avoiding relative slippage or loosening between the two during the force application process, ensuring the stability of the entire operation process, and guaranteeing the normal use and service life of the wrench.

[0013] Preferably, the reinforcing block is fixedly disposed inside the carbon fiber handle, and the two reinforcing strips are fixedly disposed inside the hollow groove, with both reinforcing strips penetrating the foam adhesive.

[0014] By adopting the above technical solution, the reinforcing block is fixed inside the carbon fiber handle, reinforcing the connection between the carbon fiber collar and the carbon fiber handle. The two reinforcing strips extend into the hollow groove of the handle and pass through the foam filling the hollow groove, so that the reinforcing block and the reinforcing strips form an integral support frame. When torque is applied with the wrench, the force is transmitted to the reinforcing block through the carbon fiber collar, and then distributed to the two reinforcing strips by the reinforcing block. This can evenly distribute the force and prevent the carbon fiber wrench handle from being deformed or broken due to excessive local stress, thus ensuring the structural stability of the wrench during long-term use.

[0015] Preferably, a rubber sleeve is fixedly connected to the outer wall of the carbon fiber handle.

[0016] By adopting the above technical solution, the rubber sleeve can form a buffer when the user holds the carbon fiber handle 7. When vibration occurs during operation, the rubber sleeve will absorb some of the vibration force, reduce the impact on the hand, thereby improving the comfort of holding, avoiding hand fatigue after long-term use, and increasing the friction between the hand and the carbon fiber handle, thereby increasing the controllability of the wrench.

[0017] Preferably, the copper component is made of beryllium bronze.

[0018] By adopting the above technical solution, the copper parts are made of beryllium bronze. Beryllium bronze has excellent wear resistance and can work for a long time with minimal wear, ensuring the service life of the wrench. It wears very little during repeated tightening operations, avoiding problems such as increased fit clearance and decreased transmission accuracy caused by wear, thereby extending the overall service life of the wrench. Moreover, beryllium bronze has good corrosion resistance and can maintain good performance even when used in some humid or slightly corrosive environments.

[0019] Preferably, both the reinforcing block and the reinforcing strip are made of nylon.

[0020] By adopting the above technical solution, both the reinforcing blocks and reinforcing strips are made of nylon material. Nylon itself has high strength and rigidity, and can provide sufficient structural support and resistance to deformation with a lighter weight.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This explosion-proof wrench for carbon fiber four-way ball valves features a secure connection formed by the interlocking of a key block on the inner wall of the carbon fiber collar and a mounting groove on the outer wall of the copper component. This prevents relative slippage when turning the valve, ensuring precise force application. The copper component, made of beryllium bronze, not only boasts excellent wear resistance, reducing wear during repeated use and extending its service life, but its knurled outer wall also increases the contact area with the carbon fiber collar, further ensuring connection stability and preventing detachment during use. The reinforcing blocks and strips on the outer wall of the carbon fiber collar are made of nylon. The reinforcing blocks are fixed inside the carbon fiber handle, reinforcing the connection between the collar and the handle. The two reinforcing strips... The foam inserts into the handle's slot and penetrates the internal filling to form an overall support frame. This evenly distributes the force, preventing excessive localized stress that could cause deformation or breakage, and ensuring structural stability over long-term use. The hollowed-out design of the carbon fiber handle's internal slot reduces overall weight, making it easier to carry and use. The foam filling the slot provides internal support for the handle through its curing and expansion effect, resulting in a more rounded shape and improved comfort. The rubber sleeve on the outer wall of the handle acts as a buffer, absorbing vibrations during operation, reducing hand impact, increasing friction, improving grip comfort and control, and preventing hand fatigue from prolonged use.

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0025] Example 1: Explosion-proof wrench for carbon fiber square ball valve, refer to Figure 1 , Figure 2 and Figure 3 The product includes a carbon fiber square ball valve explosion-proof wrench, comprising a carbon fiber collar 1 and a copper component 2. A key block 3 is fixedly connected to one side of the inner wall of the carbon fiber collar 1, and an installation groove 5 is fixedly connected to one side of the outer wall of the copper component 2. By setting the installation groove 5 on the inner wall of the carbon fiber collar 1 and the key block 3 on the outer wall of the copper component 2 to cooperate with each other, the copper component 2 is embedded into the installation groove 5 of the carbon fiber collar 1 through the key block 3, forming a stable connection to ensure that there is no relative slippage when turning the valve and to ensure precise force application. A carbon fiber handle 8 is fixedly connected to the outer wall of the carbon fiber collar 1. A hollow groove 9 is opened on one side of the inside of the carbon fiber handle 8. By setting a hollow groove 9 inside the carbon fiber handle 8, the overall weight is reduced through the hollow structure, while maintaining the structural strength of the handle, making the wrench more convenient to carry and use.

[0026] Example 2: Explosion-proof wrench for carbon fiber square ball valve, refer to Figure 2 , Figure 4 and Figure 5A reinforcing block 6 is fixedly connected to one side of the outer wall of the carbon fiber collar 1. Two mirror-distributed reinforcing strips 7 are fixedly connected to the end of the reinforcing block 6 away from the carbon fiber collar 1. The reinforcing block 6 and reinforcing strips 7 enhance the connection strength between the carbon fiber collar 1 and the carbon fiber handle 8, preventing the handle from breaking under excessive force. The cavity 9 is filled with expanding foam 10, providing space for the foam 10. Filling the cavity 9 with expanding foam 10 utilizes the expansion effect of the cured foam 10 to provide internal support for the carbon fiber handle 8, making the handle easier to mold and ensuring a more rounded shape after molding, thus improving user comfort. The outer wall of the copper part 2 is provided with knurling 4. The knurling 4 on the outer wall of the copper part 2... When bonding the copper part 2 and the carbon fiber sleeve, the contact area between them is increased to ensure the stability of the connection, enabling it to resist torsional forces and preventing relative movement or detachment. The copper part 2 is fixedly installed inside the carbon fiber collar 1, and the key block 3 is fixedly installed inside the mounting groove 5. The copper part 2 is fixed inside the carbon fiber collar 1, and the key block 3 on the inner wall of the carbon fiber collar 1 is embedded in the corresponding mounting groove 5 on the outer wall of the carbon fiber collar 1. The interlocking structure forms a stable connection. When torque is applied to the valve with a wrench, the key block 3 and the mounting groove 5 are tightly engaged, which can stably transfer the force from the carbon fiber collar 1 to the copper part 2, preventing relative sliding or loosening during the stress process and ensuring the overall stability. The stability of the operation process ensures the normal use and service life of the wrench. The reinforcing block 6 is fixedly installed inside the carbon fiber handle 8, and two reinforcing strips 7 are fixedly installed inside the slot 9. Both reinforcing strips 7 are inserted through the expanding foam 10. The reinforcing block 6, fixed inside the carbon fiber handle 8, reinforces the connection between the carbon fiber collar 1 and the carbon fiber handle 8. The two reinforcing strips 7 extend into the slot 9 of the handle and pass through the expanding foam 10 filling the slot 9, forming an integral support frame. When torque is applied using the wrench, the force is transmitted to the reinforcing block 6 through the carbon fiber collar 1, and then distributed to the two reinforcing strips 7 by the reinforcing block 6, thus evenly distributing the force and preventing excessive localized stress on the carbon fiber handle 8. To prevent deformation or breakage, the structural stability of the wrench is ensured during long-term use. A rubber sleeve 11 is fixedly connected to the outer wall of the carbon fiber handle 8. This rubber sleeve 11 acts as a buffer when the user grips the carbon fiber handle 8. When vibration occurs during operation, the rubber sleeve 11 absorbs some of the vibration force, reducing the impact on the hand and improving grip comfort. This prevents hand fatigue after prolonged use and increases the friction between the hand and the carbon fiber handle 8, thereby enhancing the wrench's controllability. The copper part 2 is made of beryllium bronze, a material with excellent wear resistance, allowing for long-term operation with minimal wear, ensuring the wrench's lifespan. Wear is minimal even during repeated tightening operations.This design avoids problems such as increased clearance and decreased transmission accuracy caused by wear, thus extending the overall service life of the wrench. Furthermore, beryllium bronze has good corrosion resistance, maintaining good performance even in humid or slightly corrosive environments. Both reinforcing block 6 and reinforcing strip 7 are made of nylon, a material known for its high strength and rigidity, providing sufficient structural support and resistance to deformation with a lighter weight.

[0027] The implementation principle of this application embodiment is as follows: Firstly, the copper part 2 and the ball valve's four-way interface are precisely matched. The knurled structure 4 on the outer wall of the copper part 2 enhances its contact area and connection stability with the inner wall of the carbon fiber collar 1. Simultaneously, the key block 3 on the inner wall of the carbon fiber collar 1 is embedded in the mounting groove 5 on the outer wall of the copper part 2, forming a mutually interlocking and stable connection structure. This ensures that when a turning force is applied to the valve, there will be no relative slippage between the copper part 2 and the carbon fiber collar 1, achieving precise force transmission from the carbon fiber collar 1 to the copper part 2. This, in turn, drives the ball valve to rotate stably to complete the valve's opening and closing operation. During the application of force, the user holds the rubber sleeve 11 on the outer wall of the carbon fiber handle 8. The rubber sleeve 11 not only increases the friction between the hand and the handle, improving operational stability, but also absorbs some of the vibration generated during operation, reducing hand impact and fatigue. Meanwhile, the hollow groove 9 inside the carbon fiber handle 8 reduces the overall weight, while the foam 10 filling the interior provides support for the handle. The internal support, along with the nylon reinforcing strip 7 running through the foam 10 and the nylon reinforcing block 6 fixed inside the carbon fiber handle 8, together form the overall support frame. When the force is transmitted from the carbon fiber collar 1 to the reinforcing block 6, the reinforcing block 6 will evenly distribute the force to the two reinforcing strips 7, effectively preventing the carbon fiber handle 8 from deforming or breaking due to excessive local stress, and ensuring the structural strength and stability of the wrench during the stress process. In addition, the beryllium bronze material used in the copper part 2 has excellent wear resistance and corrosion resistance. Even if it is used repeatedly in a humid or slightly corrosive environment, it can reduce wear and maintain good fit accuracy and transmission effect, further ensuring the long-term stable operation of the wrench. At the same time, the overall use of carbon fiber material combined with a lightweight nylon reinforcing structure reduces the overall weight of the wrench while ensuring explosion-proof performance and structural strength, improving portability and ease of operation, and reducing the fatigue of users during long-term operation.
