[0026] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0027] An anti-theft adapter ball valve includes a valve body 1. A cap 16 is fitted onto the top of the valve body 1. An end block 17 is fixedly connected to the bottom of the surface of the cap 16. An end block 2 18 located directly below the end block 17 is fixedly connected to one side of the surface of the valve body 1. The end block 17 and the end block 2 18 are sealed together by a lead seal 19. A valve stem 15 is provided through the top of the valve body 1. A nut 14 is threaded onto the top of the surface of the valve stem 15. A butterfly spring 13 is fitted onto the surface of the valve stem 15 between the valve body 1 and the nut 14.

[0028] The specific usage process is as follows: After the cap 16 is installed on the valve body 1, end block 17 and end block 2 18 are joined together vertically. Then, the lead seal 19 is inserted into end block 17 and end block 2 18, and the lead seal 19 is fused to end block 17 and end block 2 18, thereby fixing end block 17 and end block 2 18 together. In this way, the cap 16 is fixed to the valve body 1 by a lead seal, so that the cap 16 cannot move and therefore the ball valve cannot be operated to open or close, thus playing a role in preventing theft. When it is necessary to operate the ball valve, the lead seal can be cut directly, and then the ball valve can be operated. In other words, the valve body 1 and the cap 16 can be protected by a lead seal, and the valve can be prevented from being opened. To improve the safety of ball valve use and provide convenience for users, a disc spring is added between the packing and the gland. This effectively prevents loosening during long-term operation under harsh conditions of high-frequency vibration. After the positioning plate 12 is installed on the valve stem 15, the disc spring 13 is fitted on, and then the nut 14 is installed on the valve stem 15, and the disc spring 13 is tightened. Finally, the cap 16 is installed on the valve body 1. Because of the addition of the disc spring 13, the ball valve can operate for a long time under harsh conditions of high-frequency vibration, thus effectively preventing the cap 16 from loosening and falling off, providing convenience for users. When using the ball valve, the user only needs to rotate the cap 16, which will drive the valve stem 15 to rotate, and the valve stem 15 will drive the valve ball. 4. The ball 4 rotates within the valve seat 3. When the ball 4 rotates 90 degrees, the inner cavity of the ball 4 is cut off from the valve body 1 and the valve cover 7, thus cutting off the fluid flow and closing the ball valve. Rotating another 90 degrees aligns the ball 4 with the inner cavity of the valve body 1 and the valve cover 7, forming a complete channel for fluid flow, opening the ball valve and ensuring its normal operation. This provides convenience for users. The pressure ring 11 and the positioning plate 12 are both fitted onto the valve stem 15 and installed within the valve body 1. When installing the positioning plate 12, the pressure ring 11 is tightened. This tightening of the positioning plate 12 after installation increases the tightness of the positioning plate 12, providing convenience for users. The gold V-type packing 10 possesses excellent wear resistance, corrosion resistance, and high-pressure resistance, making it suitable for various applications under high temperature and high pressure. This ensures the ball valve can adapt to multiple working scenarios and operate normally even in high-temperature and high-pressure environments, providing convenience for users. The O-ring 9 serves a sealing function, installed at the joint between the cap 16 and the valve body 1 to seal the joint, ensuring the ball valve's sealing performance and providing convenience for users. The valve seat 3 is fixedly installed within the valve body 1 and is used to install the valve ball 4. The cubic design of the valve seat 3 allows for a more stable installation within the valve body 1, ensuring the valve ball 4 can open and close smoothly.To ensure the ball valve operates normally and smoothly, and to provide convenience for users, Teflon tape 6 is wrapped around the end of the valve cover 7 during installation. This seals the joint between the valve body 1 and the valve cover 7 after the valve cover 7 is installed on the valve body 1, improving the ball valve's sealing performance, preventing liquid leakage, and providing convenience for users. The flange 2 and connector 5 are connected by threads, allowing for easy adjustment of the flange 2 connection hole angle and the distance between the flange 2 and the connector, ensuring strong compatibility.

[0029] Therefore, a structural design that can prevent valve theft is adopted. When the valve is open, a lead seal is used between the valve body and the cap for protection, connecting the cap and the valve body together. This makes it difficult to operate the valve when it is open, thus achieving the purpose of preventing theft of the adapter ball valve, avoiding the theft of fluid products, reducing losses, and the valve body and cap are fixed, which will not affect normal use and can prevent the cap from being stolen, providing convenience for users' work.

[0030] A positioning piece 12 is sleeved on the surface of the valve stem 15, and the positioning piece 12 is snapped into the inside of the valve body 1. A pressure ring 11 is sleeved on the surface of the valve stem 15 and snapped into the inside of the valve body 1. The pressure ring 11 is located directly below the positioning piece 12.

[0031] Specifically, the pressure ring 11 and the positioning plate 12 are both sleeved on the valve stem 15 and installed inside the valve body 1. When the positioning plate 12 is installed, the pressure ring 11 is pressed. In this way, when the pressure ring 11 rebounds, it can increase the tightness of the positioning plate 12 after installation, providing convenience for the user's work.

[0032] One side of the inner cavity of the valve body 1 is filled with Daikin V-shaped packing 10 located below the pressure ring 11, and the Daikin V-shaped packing 10 wraps around the surface of the valve stem 15.

[0033] Specifically, the Daikin V-type packing 10 features excellent wear resistance, corrosion resistance, and high pressure resistance, making it suitable for various applications under high temperature and high pressure. This ensures that the ball valve can adapt to multiple working scenarios and operate normally in high temperature and high pressure environments, providing convenience for users.

[0034] An O-ring 9 is fitted onto the top of the surface of the valve body 1, and the O-ring 9 is located between the inner wall of the cap 16 and the outer wall of the valve body 1.

[0035] Specifically, the O-ring 9 is used to provide a seal. It is installed at the joint between the cap 16 and the valve body 1 to seal the joint, ensuring the sealing performance of the ball valve and providing convenience for users.

[0036] The bottom end of the valve stem 15 extends into the interior of the valve body 1 and is fixedly installed with a valve ball 4. A center pad 8 located inside the valve body 1 is sleeved on the bottom surface of the valve stem 15. A valve seat 3 is sleeved on the outside of the valve ball 4 and is fixedly installed inside the valve body 1.

[0037] Specifically, regarding the configuration of valve seat 3, valve ball 4, and center head gasket 8, valve seat 3 is fixedly installed inside valve body 1 and is used to install valve ball 4. Moreover, the shape of valve seat 3 is designed as a cube, so that valve seat 3 can be installed more stably inside valve body 1, thereby ensuring that valve ball 4 can open and close normally and smoothly, ensuring that the ball valve can work normally and smoothly, and providing convenience for users' work and use.

[0038] One end of the valve body 1 is connected to a valve cover 7. The valve cover 7 is wrapped with a raw material tape 6 at one end inside the valve body 1. One end of the valve body 1 is integrally formed and connected to a connector 5. A flange 2 is fitted onto the surface of the connector 5.

[0039] Specifically, regarding the installation of the valve cover 7, PTFE tape 6, connector 5, and flange 2, the PTFE tape 6 is wrapped around the end of the valve cover 7 during installation. This ensures that when the valve cover 7 is installed on the valve body 1, it can seal the joint between the valve body 1 and the valve cover 7, thereby improving the sealing performance of the ball valve, preventing liquid leakage, and providing convenience for users. The flange 2 and connector 5 are connected by threads, allowing for arbitrary changes to the angle of the flange 2 connection hole and the distance between the flange 2 and the connector, resulting in strong compatibility.

[0040] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).
