Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically a flanged ball valve that does not require heat fusion bonding. Background Technology

[0002] Ball valves are widely used in industrial pipeline systems. They open, close, or regulate the flow of media by rotating a ball. Flanged ball valves are a type of ball valve, characterized by their compact structure, light weight, low fluid resistance, good sealing performance, and ease of operation. They are typically used to shut off or connect media in pipelines and are suitable for various media such as water, steam, oil, and natural gas. They can also operate stably under high temperature and high pressure environments.

[0003] During the use of this flanged ball valve, the two sides of the valve body are first connected to the conveying pipeline. Then, the handle is turned to rotate the ball, causing it to rotate around the center line of the valve body to open and close. In the closed state, the ball is tightly fitted with the valve seat, blocking the flow of the medium. In the open state, the ball rotates 90 degrees, allowing the medium to pass through smoothly. However, ball valves are usually installed using hot-melt bonding. This installation method requires first using a heating element to fuse the pipeline and flange together to form a strong connection before the ball valve can be installed. However, this installation method is relatively cumbersome and time-consuming, making it difficult to achieve rapid installation of flanged ball valves, thus affecting the installation efficiency of flanged ball valves and consequently affecting their use. Utility Model Content

[0004] The purpose of this invention is to provide a flanged ball valve that does not require heat fusion bonding, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flanged ball valve that does not require heat fusion bonding, comprising a ball valve body, a handle and a first flange, wherein the handle is rotatably connected to the top center of the ball valve body, and the first flange is connected to one side of the inside of the ball valve body, and a second flange is connected to the other side of the inside of the ball valve body.

[0006] Preferably, a first fixing seat is connected to one side of the outer wall of the ball valve body, and a second fixing seat is connected to the other side of the outer wall of the ball valve body.

[0007] Preferably, the first fixing seat is internally connected to a first snap-fit ​​flange, and the second fixing seat is internally connected to a second snap-fit ​​flange.

[0008] Preferably, both the first flange and the second flange have mounting holes on one side of their outer walls, and the mounting holes are distributed at an angle on the first flange.

[0009] Preferably, a limiting groove corresponding to the first snap-fit ​​flange is provided in the middle of the outer wall of the first flange, and an inlet is provided on the side of the ball valve body near the first flange.

[0010] Preferably, the ball valve body has a conveying channel inside, and the ball valve body has an output port on the side near the second flange.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this flanged ball valve that does not require heat fusion bonding, the first flange and the second flange are moved sequentially to the designated positions, thereby eliminating the need for heat fusion bonding and completing the installation of the flanged ball valve. This simplifies the installation process, shortens on-site operation time, improves work efficiency, and reduces the impact of high-temperature operations on the valve and pipeline by avoiding high-temperature operations. It also reduces the safety risks caused by high-temperature operations and improves the safety of on-site operations. Thus, when using the flanged ball valve, it facilitates quick connection and improves work efficiency. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5This utility model provides a technical solution: a flanged ball valve that does not require heat fusion bonding, comprising a ball valve body 1, a handle 2, and a first flange 3. The handle 2 is rotatably connected to the top center of the ball valve body 1, and the first flange 3 is connected to one side of the inside of the ball valve body 1, while a second flange 4 is connected to the other side of the inside of the ball valve body 1. A first fixing seat 5 is mated to one side of the outer wall of the ball valve body 1, and a second fixing seat 6 is mated to the other side of the outer wall of the ball valve body 1. A first snap-fit ​​flange 7 is connected inside the first fixing seat 5, and a second snap-fit ​​flange 8 is connected inside the second fixing seat 6. Both the first flange 3 and the second flange 4 have mounting holes 9 on one side of their outer walls, and the mounting holes 9 are distributed at equal angles on the first flange 3; the first flange 3 has a limiting groove corresponding to the first snap-fit ​​flange 7 in the middle of its outer wall, and the ball valve body 1 has an inlet on the side near the first flange 3; the ball valve body 1 has a conveying channel inside, and the ball valve body 1 has an outlet on the side near the second flange 4; the handle 2 has a width that decreases from the middle to both sides, and the second flange 4 has a limiting cavity corresponding to the second snap-fit ​​flange 8 in the middle of its wall, and the mounting holes 9 are distributed at equal angles on the second flange 4.

[0020] In specific implementation, during the use of this flanged ball valve, in order to quickly improve working efficiency, the first fixed seat 5 is first fitted onto the outside of the first flange 3, and the second fixed seat 6 is fitted onto the outside of the second flange 4. Then, the first snap-fit ​​flange 7 is moved into the inside of the first fixed seat 5, so that the first snap-fit ​​flange 7 is located on the outside of the first flange 3. Then, the second snap-fit ​​flange 8 is moved into the inside of the second fixed seat 6, so that the second snap-fit ​​flange 8 is located on the outside of the second flange 4. After that, the first flange 3 is moved to mate with one side of the ball valve body 1, and the second flange 4 is moved to mate with the other side of the ball valve body 1. Thus, the first fixed seat 5 and the second fixed seat 6 are respectively located on both sides of the ball valve body 1.

[0021] Because the outer wall of the first flange 3 has a limiting groove corresponding to the first snap-fit ​​flange 7, and the outer wall of the second flange 4 has a limiting cavity corresponding to the second snap-fit ​​flange 8, the first fixed seat 5 and the second fixed seat 6 are pushed in sequence. Then, the first fixed seat 5 moves and drives the first snap-fit ​​flange 7 to move, and the second fixed seat 6 moves and drives the second snap-fit ​​flange 8 to move, until the first snap-fit ​​flange 7 and the second snap-fit ​​flange 8 move to the designated position, thereby fixing the first flange 3 and the second flange 4 to the ball valve body 1 to prevent them from moving at will. Thus, the installation of the flanged ball valve can be completed without the need for hot melt bonding. Furthermore, because the outer walls of the first flange 3 and the second flange 4 both have mounting holes 9, bolts can be inserted through the mounting holes 9 to facilitate the connection of the flanged ball valve to the conveying pipeline.

[0022] Because flanged ball valves can be installed without the need for heat fusion equipment, the installation process is simplified, on-site operation time is shortened, and work efficiency is improved. Especially in situations requiring quick replacement or maintenance, the heat-free bonding flanged ball valve demonstrates its convenience. Furthermore, since the installation process does not involve high-temperature operations, it reduces the impact of thermal stress on valves and pipelines, lowers long-term maintenance costs, and reduces safety risks associated with high-temperature operations, thereby improving on-site safety. It also eliminates the fumes and harmful substances generated during the heat fusion process, making it more environmentally friendly. Ultimately, when using flanged ball valves, it facilitates quick connection and improves work efficiency.

[0023] In summary, when using this heat-fusion-free flanged ball valve, first connect both sides of the ball valve body 1 to the conveying pipeline, then rotate the handle 2 to rotate the ball around the valve body's center line to open and close it. In the closed state, the ball is tightly fitted to the valve seat, blocking the flow of media. In the open state, the ball rotates 90 degrees, allowing the media to pass smoothly. This is existing technology and will not be elaborated further. By sequentially moving the first flange 3 and the second flange 4, the first snap-fit ​​flange 7 and the second snap-fit ​​flange 8 are moved to the designated positions, thus eliminating the need for heat fusion bonding and completing the installation of the flanged ball valve. This simplifies the installation process and improves efficiency. This technology improves work efficiency and avoids high-temperature operations during installation, reducing the impact of thermal stress on valves and pipelines. Traditional hot-melt bonding may involve the use of high temperatures and potentially harmful adhesives, which may release volatile organic compounds and other pollutants. Hot-melt bonding technology helps reduce the emission of these harmful substances by avoiding these high temperatures and the use of chemical adhesives. Furthermore, hot-melt bonding of flanged ball valves makes maintenance and replacement simpler and faster, reducing downtime during maintenance. This is highly beneficial for maintaining continuous production line operation and reducing energy waste. Any content not described in detail in this specification is prior art known to those skilled in the art.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
