Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, and in particular to a ball valve that is easy to install. Background Technology

[0002] In pipeline connection systems, ball valves are key components for controlling fluid flow and switching, and ease of installation is of paramount importance.

[0003] Currently, ball valves are mainly connected to pipelines via threaded connections and flange connections. While threaded connections have a compact structure, installation requires repeated tightening with tools such as wrenches, which is time-consuming and labor-intensive. Furthermore, frequent disassembly and assembly can lead to thread wear and stripping, affecting the connection's stability. Flange connections offer better sealing, but installation requires aligning multiple bolt holes and tightening nuts one by one, which is not only cumbersome and requires complex tools, but also demands high technical skills from installers, resulting in low installation efficiency. In addition, both threaded and flange connections require significant time and effort for disassembly, inspection, and maintenance, making it difficult to meet the frequent disassembly and assembly needs of ball valves in industrial production. Therefore, we have introduced a new ball valve that is easy to install. Utility Model Content

[0004] The main objective of this invention is to provide a ball valve that is easy to install, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An easy-to-install ball valve includes a valve body. Connecting seats are fixedly installed at both the left and right ends of the valve body. Locking mechanisms are movably connected to the upper and lower middle parts of the two connecting seats. Fixing blocks are fixedly connected to the outer sides of the upper and lower ends of the two connecting seats. Pins are inserted into each of the four fixing blocks. Connecting grooves are formed at the ends of the two connecting seats away from the valve body. Connecting mechanisms are inserted into each of the two connecting grooves. A numbered mark is provided at the upper and lower parts of the ends of the two connecting seats away from the valve body. Elastic grooves are formed on the upper and lower inner walls of the two connecting grooves. Sliding grooves are formed on the left and right walls of the four elastic grooves.

[0007] Preferably, the locking mechanism includes a locking block, with sliders fixedly connected to the upper left and upper right parts of the outer surface of the locking block, a spring and a connecting rod fixedly connected to the middle of the upper end of the locking block, a through-hole No. 1 opened on the upper part of the outer surface of the connecting rod, a pull rod fixedly connected to the upper end of the connecting rod, a through-hole No. 2 opened on the upper part of the outer surface of the pull rod, and a pull handle fixedly connected to the upper end of the pull rod.

[0008] Preferably, the lower part of the locking block is located in the connecting groove, and the locking block is slidably connected to the elastic groove. The upper end of the spring is fixedly connected to the upper groove wall of the elastic groove, and the spring is located outside the connecting rod.

[0009] By adopting the above technical solution, the locking block is automatically engaged into the corresponding locking groove outside the connecting pipe under the reset action of the spring, making it convenient and quick to install and connect the connecting pipe and the valve body.

[0010] Preferably, the connecting rod is movably connected to the upper wall of the elastic groove, and both the first and second insertion holes are connected to the pins.

[0011] By adopting the above technical solution: when the pin is connected to the first socket, the locking block can be located in the elastic groove, so that the connecting tube can be smoothly inserted into the connecting groove. When the pin is connected to the second socket, the pull rod can be further locked to prevent the lock from loosening.

[0012] Preferably, the connecting mechanism includes a connecting pipe, with a second marking line provided on the upper and lower parts of the outer surface of the connecting pipe, a locking groove provided on the right side of the upper part of the connecting pipe and the right side of the lower part of the outer surface, and a sealing ring provided at the right end of the connecting pipe.

[0013] Preferably, the connecting pipe is inserted into the connecting groove, and the sealing ring is tightly fitted to the right wall of the connecting groove.

[0014] By adopting the above technical solution, the sealing performance of the connection can be improved through the use of sealing rings.

[0015] Preferably, the two locking grooves are respectively engaged with the two locking blocks, and the two second markings correspond to the positions of the two first markings.

[0016] By adopting the above technical solution, the No. 2 marking line is aligned with the No. 1 marking line on the connecting seat, which can quickly correspond to the positions of the two locking grooves and the locking block, thus improving installation efficiency.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Pull up the lever to move the locking block into the elastic groove and compress the spring. Then insert the pin into the first socket to allow the connecting pipe to be smoothly inserted into the connecting groove. Then pull the pin out of the first socket. Under the reset action of the spring, the locking block will automatically engage with the corresponding locking groove on the outside of the connecting pipe. Then insert the pin into the second socket. This allows the connecting pipe and the valve body to be easily and quickly connected. Compared with traditional threaded or flanged connections, no complicated tools are needed, and it is also convenient to disassemble, inspect or maintain them later. It is especially suitable for scenarios that require frequent disassembly and assembly.

[0019] 2. When the connecting pipe is inserted into the connecting groove, the sealing ring fits tightly against the inner wall of the connecting groove, which can enhance the sealing performance of the connection. At the same time, the No. 2 markings set on the upper and lower parts of the connecting pipe are aligned with the No. 1 marking on the connecting seat, which can quickly correspond to the positions of the two locking grooves and locking blocks. This not only improves the reliability of the connection through the sealing structure, but also realizes the quick alignment of the locking components with the help of the markings, thereby improving the installation efficiency of the connecting pipe and the ball valve.

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] A ball valve that is easy to install includes a valve body 1. Connecting seats 2 are fixedly installed on the left and right ends of the valve body 1. Locking mechanisms 3 are movably connected to the middle of the upper and lower ends of the two connecting seats 2. Fixing blocks 4 are fixedly connected to the outer sides of the upper and lower ends of the two connecting seats 2. Pins 5 are inserted into the four fixing blocks 4. Connecting grooves 6 are opened at the ends of the two connecting seats 2 away from the valve body 1. Connecting mechanisms 7 are inserted into the two connecting grooves 6. A first mark 8 is provided at the upper and lower parts of the ends of the two connecting seats 2 away from the valve body 1. Elastic grooves 9 are opened on the upper and lower inner walls of the two connecting grooves 6. Sliding grooves 10 are opened on the left and right walls of the four elastic grooves 9.

[0030] In this embodiment, the locking mechanism 3 includes a locking block 31. Slider 32 is fixedly connected to the upper left and upper right parts of the outer surface of the locking block 31. A spring 33 and a connecting rod 34 are fixedly connected to the middle of the upper end of the locking block 31. A through-hole 35 is opened on the upper part of the outer surface of the connecting rod 34. A pull rod 36 is fixedly connected to the upper end of the connecting rod 34. A through-hole 37 is opened on the upper part of the outer surface of the pull rod 36. A handle 38 is fixedly connected to the upper end of the pull rod 36. The lower part of the locking block 31 is located in the connecting groove 6, and the locking block 31 is slidably connected to the elastic groove 9. The upper end of the spring 33 is fixedly connected to the upper groove wall of the elastic groove 9, and the spring 33 is located outside the connecting rod 34. The connecting rod 34 is movably connected to the upper groove wall of the elastic groove 9. Both the first and second holes 35 are inserted into the pin 5.

[0031] The above method involves pulling up the lever 36 using the handle 38, causing the locking block 31 to move into the elastic groove 9 and compress the spring 33. Then, the pin 5 is inserted into the first socket 35, allowing the connecting pipe 71 to be smoothly inserted into the connecting groove 6. The pin 5 is then pulled out of the first socket 35, and under the reset action of the spring 33, the locking block 31 automatically engages with the corresponding locking groove 73 on the outside of the connecting pipe 71. Finally, the pin 5 is inserted into the second socket 37, thus enabling the connecting pipe 71 to be easily and quickly installed and connected to the valve body 1.

[0032] In this embodiment, the connecting mechanism 7 includes a connecting pipe 71. The upper and lower parts of the outer surface of the connecting pipe 71 are provided with second-level marking lines 72. The upper right side of the outer surface of the connecting pipe 71 and the lower right side of the outer surface are provided with locking grooves 73. A sealing ring 74 is provided at the right end of the connecting pipe 71. The connecting pipe 71 is inserted and connected to the connecting groove 6. The sealing ring 74 is tightly fitted to the right groove wall of the connecting groove 6. The two locking grooves 73 are respectively engaged with the two locking blocks 31. The two second-level marking lines 72 correspond to the positions of the two first-level marking lines 8.

[0033] With the above solution, when the connecting pipe 71 is inserted into the connecting groove 6, the sealing ring 74 fits tightly against the inner wall of the connecting groove 6, which can enhance the connection sealing performance. At the same time, the second mark 72 set on the upper and lower parts of the connecting pipe 71 is aligned with the first mark 8 on the connecting seat 2, which can quickly correspond to the positions of the two locking grooves 73 and the locking block 31. This not only improves the reliability of the connection through the sealing structure, but also realizes the quick alignment of the locking components by means of the mark positioning, thereby improving the installation efficiency of the connecting pipe 71 and the valve body 1.

[0034] It should be noted that this utility model is a ball valve that is easy to install. During use, the lever 36 is pulled by the handle 38. At this time, the locking block 31 will move towards the inside of the elastic groove 9 and compress the spring 33. Then, the pin 5 is inserted into the first insertion hole 35, creating conditions for the connecting pipe 71 to be inserted into the connecting groove 6. During the process of the connecting pipe 71 being inserted into the connecting groove 6, the sealing ring 74 will fit tightly against the inner wall of the connecting groove 6, enhancing the sealing performance of the connection. At the same time, the second mark 72 set on the upper and lower parts of the connecting pipe 71 will be aligned with the first mark 8 on the connecting seat 2. With the help of this mark alignment method, the corresponding positions of the two locking grooves 73 and the locking block 31 can be quickly determined, that is, by... The sealing structure improves the reliability of the connection, and the markings enable quick alignment of the locking components. After the connecting pipe 71 is fully inserted into the connecting groove 6, the pin 5 is pulled out from the first insertion hole 35. At this time, under the reset action of the spring 33, the locking block 31 will automatically engage with the corresponding locking groove 73 on the outside of the connecting pipe 71. Then, the pin 5 is inserted into the second insertion hole 37. In this way, the connecting pipe 71 and the valve body 1 are connected in a convenient and quick manner. Compared with the traditional threaded or flanged connection, this connection method does not require complicated tools, which can improve the installation efficiency and is more convenient for subsequent disassembly, inspection or maintenance. It is especially suitable for scenarios that require frequent disassembly and assembly.
