[0017] The present invention will be described in further detail below with reference to the accompanying drawings.

[0018] Embodiment: A ball valve support device, such as Figure 1 and Figure 2As shown, it includes an installation support base plate 1 and a valve body support assembly movably connected to the installation support base plate 1. A plurality of installation fastening holes 2 are provided on the installation support base plate. During the installation of a ball valve of a specified model, the installer selects a ball valve support device of corresponding specifications and first pre-installs the installation support base plate 1 through the installation fastening holes 2 to complete the fixation of the installation support base plate 1 to the installation surface such as the equipment or wall.

[0019] like Figure 1 、 Figure 2 and Figure 3 As shown, the valve body support assembly includes a positioning support 3 and a locking support 4 that are slidingly connected to the mounting support base plate 1. The positioning support 3 and the locking support 4 can be flexibly combined to achieve limited support for the ball valve body. The cam 6 is fixed to the cam 6 by bolts, and the cam 6 is fixed to the cam 6 by bolts. Considering the matching work between the semicircular groove 10 and the flange block on the ball valve body, a bolt slot piece 23 is rotatably connected to the notch of the semicircular groove 10. The bolt slot piece 23 is provided with multiple bolt slots 24. The installer can achieve precise fit between the fastening bolts on the ball valve flange block and the multiple bolt slots 24 through flexible adjustment, thereby ensuring the sufficient limit fastening effect of the pair of valve body sleeves 8. After completing the installation of the ball valve fastening sleeve, the installer flexibly completes the bolt fastening of the positioning block 6 and the positioning groove 5, and finally completes the locking and fixation of one end of the ball valve.

[0020] After completing the fixation of the medium input end of the ball valve, the installer flexibly achieves further support and protection of the ball valve as a whole through the locking support 4. A locking groove 12 is provided on the installation support base plate 1. The locking support 4 includes a movable support block 13 slidingly connected to the locking groove 12 and a ball valve limit block 14 fixed on the movable support block 13. A semi-arc card groove 15 is provided on the ball valve limit block 14, and the semi-arc card groove 15 is used to realize the sleeve support of the flange part of the other end of the ball valve. A spiral locking block 16 is fixed to the notch at the end of the locking groove 12 away from the positioning support 3. A locking screw 17 is threadedly connected to the spiral locking block 16, and a threaded hole 18 for threading the locking screw 17 is provided on the movable support block 13. The installer continues to rotate the locking screw 17 to drive the movable support block 13 to slide and tighten toward one side of the positioning support 3, and finally completes the support and support of the two ends of the ball valve by the locking supports 4 and the positioning supports 3 on both sides. In order to further ensure the locking and fixing effect of the movable support block 13, horizontal support blocks 19 (such as Figure 4 As shown), the horizontal support block 19 is provided with an auxiliary latch block 20 (as Figure 4 As shown, the mounting support base plate 1 is provided with a plurality of auxiliary pin holes 21 (as shown Figure 4 As shown, after the movable support block 13 has been adjusted, the installer can further secure it by simply inserting the auxiliary latch block 20 into the designated auxiliary latch hole 21. A horizontal scale block is provided on the installation support base plate 1, providing a convenient reference for the installer during assembly, and allowing the installer to determine the adequacy of the support and locking of the ball valve body in conjunction with the relevant specifications of the specified ball valve body.

[0021] Considering that the ball valve body may experience resonance when conveying fluid during actual operation, shock-absorbing pads 22 are installed at the bottom of the flange groove 11 and the semi-arc groove 15. This not only improves the tightness of the flange groove 11 and the semi-arc groove 15, but also helps to consistently buffer and absorb vibrations during pipeline transportation, reducing the potential impact of vibration on the support device and its impact on the support structure. A reinforcement block 25 is also installed between the positioning block 6 and the support leg 7, effectively ensuring the compressive strength of the positioning support 3 and improving the reliability of the support.

[0022] In view of the large distance between the positioning support 3 and the locking support 4 caused by the larger length and volume of some ball valve bodies, a plurality of movable protective supports 26 are also slidably connected to the installation support base plate 1. The movable protective supports 26 are arranged between the positioning support 3 and the locking support 4, and can achieve further support and limiting support for the ball valve according to the flexible adjustment of the installer.

[0023] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
