This requires numerous steps during installation, making it inconvenient to both install and disassemble the valve stem. This reduces the efficiency of ball valve installation and diminishes the practicality of the ball valve. Summary of the Invention

[0004] This utility model addresses the problem that the valve stem of a track-type ball valve is fixed to the ball valve body using multiple pins and screws, requiring numerous steps during installation. This not only makes it inconvenient to install the valve stem but also to disassemble it, reducing the efficiency and practicality of the ball valve body. Therefore, this invention proposes a ball valve body with a convenient track-type valve stem installation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a ball valve body with a convenient track-type valve stem installation, comprising a ball body, a valve seat fixedly connected to the outer surface of the ball body, a connecting ring fixedly connected to the top of the outer surface of the ball body, a valve stem body inserted into the inner wall of the ball body, an installation device provided between the valve stem body and the connecting ring, the installation device comprising two clamping plates, both clamping plates being disposed inside the connecting ring, the two clamping plates being disposed on both sides of the valve stem body, a threaded rod fixedly connected to the side of the two clamping plates that is far apart, a threaded cylinder threadedly connected to the outer surface of the threaded rod, the outer surface of the threaded cylinder being disposed on the inner wall of the connecting ring, pins fixedly connected to the side of the two clamping plates that is close to each other, an insertion hole being opened on the outer surface of the valve stem body, the outer surfaces of the two pins being inserted into the inner wall of the insertion hole, an auxiliary device being provided at the top of the connecting ring, and a handwheel fixedly connected to the top of the valve stem body.

[0006] The effect achieved by the above components is as follows: by setting two clamping plates with pins, the threaded cylinder is rotated under the action of the threaded rod. The threaded cylinder will drive the threaded rod to extend and retract on the inner wall of the threaded cylinder. During the extension and retraction process, the threaded rod will drive the clamping plates and pins to move until the two clamping plates completely clamp the outer surface of the valve stem body and the pin is fully inserted into the inner wall of the insertion hole. This allows for quick fixation between the ball body and the valve stem body, effectively reducing the operation steps in the installation process. It is convenient to install the valve stem body and also convenient to disassemble the valve stem body, thus improving the practicality of the ball valve ball.

[0007] Preferably, a slider is fixedly connected to one side of the clamping plate, and symmetrical grooves are provided at the bottom of the inner wall of the connecting ring, with the outer surface of the slider slidably connected to the inner wall of the groove.

[0008] The effect achieved by the above components is as follows: by setting the slider and the groove, when the clamping plate moves under the action of the threaded rod, the clamping plate will drive the slider to slide synchronously on the inner wall of the groove, which can limit the clamping plate.

At the same time, by setting an auxiliary groove, the operating block can be accommodated, which helps to prevent the operating block from obstructing the installation of the ball valve ball.

[0011] Preferably, a bearing is fixedly connected to the outer surface of the threaded cylinder, and the outer surface of the bearing is fixedly connected to the inner wall of the connecting ring.

[0012] The effect achieved by the above components is that by setting bearings, the friction between the threaded cylinder and the inner wall of the connecting ring can be reduced when rotating the threaded cylinder, making it easier to rotate the threaded cylinder.

[0013] Preferably, a rubber plate is fixedly connected to one side of each of the two clamping plates that are close to each other, and the outer surface of the pin is inserted into the inner wall of the rubber plate.

[0014] The effect achieved by the above components is as follows: by setting the rubber plate, one side of the clamp can be replaced to abut against the outer surface of the valve stem body, and the friction between the clamp and the valve stem body can be increased, making the clamp more stable in holding the valve stem body, and improving the stability of the connection between the valve stem body and the ball body.

[0015] Preferably, the auxiliary device includes a protective plate, which is disposed on the top of the connecting ring, and the outer surface of the valve stem body is inserted into the inner wall of the protective plate.

[0016] The effect achieved by the above components is as follows: by setting up a protective plate, the protective plate can cover and seal the top of the connecting ring, which helps to prevent foreign objects from entering the interior of the connecting ring and causing obstruction to the internal components of the connecting ring, and facilitates the adjustment of the clamp.

[0017] Preferably, four threaded pins are evenly fixedly connected to the top of the connecting ring, the outer surface of the threaded pins is inserted into the inner wall of the protective plate, and a nut is threaded onto the outer surface of the threaded pins.

[0018] The effect achieved by the above components is as follows: by setting threaded pins, inserting four threaded pins into the inner wall of the protective plate, and then putting a nut on one end of the threaded pin, rotating the nut so that one side of the nut abuts against one side of the protective plate, the protective plate and the connecting ring can be fixed, which helps to prevent the connecting ring from detaching from the protection of the protective plate.

[0019] Preferably, a rubber pad is fixedly connected to one side of the nut, and the outer surface of the threaded pin is inserted into the inner wall of the rubber pad.

[0020] The effect achieved by the above-mentioned components is that by setting a rubber pad, one side of the nut can be replaced by the other side of the protective plate, and the friction between the nut and the protective plate can be increased, which helps to prevent the nut from loosening.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting two clamping plates with pins, the threaded rod can drive the clamping plates and pins to move until the two clamping plates completely clamp the outer surface of the valve stem body and the pins are fully inserted into the inner wall of the insertion hole. This allows for quick fixation between the ball body and the valve stem body, effectively reducing the number of operation steps in the installation process.

[0028] Example 1, referring to Figures 1-3 As shown, this embodiment discloses a ball valve body with a convenient track-type valve stem installation, including a ball body 1. A valve seat 2 is fixedly connected to the outer surface of the ball body 1, and a connecting ring 3 is fixedly connected to the top of the outer surface of the ball body 1. A valve stem body 4 is inserted into the inner wall of the ball body 1. An installation device 5 is provided between the valve stem body 4 and the connecting ring 3. The installation device 5 includes two clamping plates 51, both of which are located inside the connecting ring 3 and on both sides of the valve stem body 4. A threaded rod 52 is fixedly connected to the side of the two clamping plates 51 that is far apart from each other. A threaded cylinder 53 is threadedly connected to the outer surface of the threaded rod 52. The outer surface of the threaded cylinder 53 is located on the inner wall of the connecting ring 3. A pin 54 is fixedly connected to the side of the two clamping plates 51 that is close to each other. An insertion hole 55 is provided on the outer surface of the valve stem body 4. The outer surfaces of the two pins 54 are inserted into the inner wall of the socket 55. An auxiliary device 6 is provided on the top of the connecting ring 3. A handwheel 7 is fixedly connected to the top of the valve stem body 4. By setting two clamping plates 51 with pins 54, the threaded cylinder 53 is rotated under the action of the threaded rod 52. The threaded cylinder 53 will drive the threaded rod 52 to extend and retract on the inner wall of the threaded cylinder 53. During the extension and retraction, the threaded rod 52 will drive the clamping plates 51 and the pins 54 to move until the two clamping plates 51 completely clamp the outer surface of the valve stem body 4 and the pins 54 are completely inserted into the inner wall of the socket 55. This allows for quick fixation between the ball body 1 and the valve stem body 4, effectively reducing the operation steps in the installation process. It is convenient to install the valve stem body 4 and also convenient to disassemble the valve stem body 4, thus improving the practicality of the ball valve ball.

[0029] Reference Figure 2 and Figure 3As shown, a slider 56 is fixedly connected to one side of the clamping plate 51. A sliding groove 57 is symmetrically opened at the bottom of the inner wall of the connecting ring 3. The outer surface of the slider 56 is slidably connected to the inner wall of the sliding groove 57. By setting the slider 56 and the sliding groove 57, when the clamping plate 51 moves under the action of the threaded rod 52, the clamping plate 51 will drive the slider 56 to slide synchronously on the inner wall of the sliding groove 57, which can limit the clamping plate 51. An operating block 58 is fixedly connected to one end of the threaded cylinder 53. A regular hexagonal groove is opened on one side of the operating block 58. An auxiliary groove 59 is symmetrically opened on the outer surface of the connecting ring 3. The operating block 58 is set inside the auxiliary groove 59. By setting the operating block 58 with the regular hexagonal groove, it is easy to rotate the operating block 58 with a hex wrench, which facilitates the adjustment of the clamping plate 51. At the same time, by setting the auxiliary groove 59, the operating block 58 can be accommodated, which helps to prevent the operating block 58 from obstructing the installation of the ball valve ball.

[0030] Reference Figure 2 and Figure 3 As shown, a bearing 510 is fixedly connected to the outer surface of the threaded cylinder 53. The outer surface of the bearing 510 is fixedly connected to the inner wall of the connecting ring 3. By setting the bearing 510, the friction between the threaded cylinder 53 and the inner wall of the connecting ring 3 can be reduced when rotating the threaded cylinder 53, making it easier to rotate the threaded cylinder 53. A rubber plate 511 is fixedly connected to one side of the two clamping plates 51 that are close to each other. The outer surface of the pin 54 is inserted into the inner wall of the rubber plate 511. By setting the rubber plate 511, it can replace one side of the clamping plate 51 to abut against the outer surface of the valve stem body 4, and can increase the friction between the clamping plate 51 and the valve stem body 4, making the clamping of the valve stem body 4 by the clamping plate 51 more stable and improving the stability of the connection between the valve stem body 4 and the ball body 1.

[0031] Reference Figure 4 As shown, the auxiliary device 6 includes a protective plate 61, which is set on the top of the connecting ring 3. The outer surface of the valve stem body 4 is inserted into the inner wall of the protective plate 61. By setting the protective plate 61, the protective plate 61 can cover and seal the top of the connecting ring 3, which helps to prevent foreign objects from entering the interior of the connecting ring 3 and causing obstruction to the internal components of the connecting ring 3, and facilitates the adjustment of the clamp 51.

[0032] Reference Figure 4As shown, four threaded pins 62 are evenly fixedly connected to the top of the connecting ring 3. The outer surface of the threaded pins 62 is inserted into the inner wall of the protective plate 61. Nuts 63 are threadedly connected to the outer surface of the threaded pins 62. By setting the threaded pins 62, all four threaded pins 62 are inserted into the inner wall of the protective plate 61. Then, the nuts 63 are sleeved on one end of the threaded pins 62. By rotating the nuts 63, one side of the nuts 63 abuts against one side of the protective plate 61, which can fix the protective plate 61 and the connecting ring 3, and help prevent the connecting ring 3 from detaching from the protection of the protective plate 61. A rubber pad 64 is fixedly connected to one side of the nuts 63. The outer surface of the threaded pins 62 is inserted into the inner wall of the rubber pad 64. By setting the rubber pad 64, one side of the nuts 63 can abut against one side of the protective plate 61, and increase the friction between the nuts 63 and the protective plate 61, which helps prevent the nuts 63 from loosening.

[0033] Working principle: When the valve stem body 4 needs to be installed, insert the valve stem body 4 into the inner wall of the ball body 1, and align the pin 54 with the insertion hole 55. Rotate the two operating blocks 58 to drive the threaded cylinder 53 to rotate. The threaded cylinder 53 will drive the threaded rod 52 to extend and retract within the inner wall of the threaded cylinder 53. Under the limit of the slider 56 and the slide groove 57, the threaded rod 52 will drive the clamping plate 51 and the pin 54 to move until the rubber plate 511 on one side of the two clamping plates 51 completely clamps the outer surface of the valve stem body 4 and the pin 54 is fully inserted into the inner wall of the insertion hole 55. The quick fixation between the ball body 1 and the valve stem body 4 can effectively reduce the number of operation steps in the installation process. When it is necessary to install the protective plate 61, place the protective plate 61 on top of the connecting ring 3, and insert the four threaded pins 62 and the valve stem body 4 into the inner wall of the protective plate 61. Then, put the nut 63 on one end of the threaded pin 62 and rotate the nut 63 so that the rubber pad 64 on one side of the nut 63 abuts against one side of the protective plate 61. This can fix the protective plate 61 and the connecting ring 3, which helps to prevent the connecting ring 3 from falling off the protection of the protective plate 61.
