DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment: As Figures 1-3 shown, the present utility model provides a convenient and quickly detachable pneumatic plug valve, which includes a valve frame 1. The valve frame 1 serves as the main frame of the entire device, and an insertion plate mechanism 2 is fixedly arranged inside it. The core of the insertion plate mechanism 2 is a cylinder 20. One side of the cylinder 20 is fixedly connected to one side of the valve frame 1 in close contact, ensuring the stability of power transmission. The output end of the cylinder 20 is provided with a valve plate 26, and sliding plates 21 are fixedly arranged on both sides of the valve plate 26. One of the sliding plates 21 is closely connected to the output end of the cylinder 20, ensuring the guiding and stability of the valve plate 26 during movement. Connecting plates 28 are fixedly arranged on both sides of the valve frame 1, and water passing ports 27 are arranged on the connecting plates 28. The water passing ports 27 are matched with the valve ports 24 on the valve plate 26 through water passing grooves 25 to achieve the control of fluid.

[0020] By adding the cooperation of a sliding block 22 and a sliding groove 29, the stability and accuracy of the valve plate 26 during movement are further enhanced. The connecting holes 23 are annularly distributed on one side of the water passing port 27 and the number is as many as nine, improving the adaptability and flexibility of the valve to pipelines or other connectors. The design of the close sliding fit between the upper and lower ends of the two sliding plates 21 and the upper and lower inner walls of the valve frame 1 not only reduces the frictional resistance, ensures the smooth movement of the valve plate 26, but also further improves the sealing performance of the valve.

[0021] The mounting plate 30 serves as the mounting base of the quick detaching mechanism 3. Two mounting screw cylinders 38 are fixedly arranged on one side of it. The mounting screw cylinders 38 are sleeved with mounting screw rods 32 through threads to achieve the function of rotational movement. One end of the mounting screw rod 32 is fixedly provided with a limiting rod 33, and the limiting rod 33 is then connected to a limiting clamping rod 34. Such a design not only ensures the stability during the installation process but also facilitates subsequent disassembly operations. At the same time, a plurality of limiting beads 35 are arranged on the outer surface of the mounting screw cylinder 38. These limiting beads 35 are used in cooperation with the limiting rod 33 and the limiting clamping rod 34. In addition, a limiting card slot 37 is opened on the mounting screw cylinder 38 to provide precise guiding and positioning for the limiting clamping rod 34, ensuring the accuracy and stability during the installation process.

[0022] By providing a limit groove 36 on the outer surface of the mounting barrel 38 and using it in conjunction with the limit bead 35, precise limitation of the mounting screw 32 and the limit rod 33 is achieved. The limit card slot 37 is ingeniously combined with the limit card rod 34, providing a reliable locking mechanism for the quick-release mechanism 3. By adding a knob 31 at one end of the mounting screw 32, a more convenient operation method is provided for the user.

[0023] Working principle: When it is necessary to open or close the valve, the cylinder 20 receives a control signal and starts, and its output end pushes or pulls the connected sliding plate 21 and the valve plate 26. Under the guidance of the sliding plate 21, the valve plate 26 moves smoothly along the preset sliding groove 29 inside the valve housing 1. The valve orifice 24 on the valve plate 26 cooperates with the water passage groove 25 on the connecting plate 28, and by adjusting the relative position of the valve orifice 24 and the water passage groove 25, the on-off control of the fluid is realized. During the whole process, the close fit between the sliding block 22 and the sliding groove 29 ensures the accuracy and stability of the movement of the valve plate 26, thus ensuring the sealing performance of the valve and the accuracy of fluid control.

[0024] By adding the cooperation between the sliding block 22 and the sliding groove 29, the stability and accuracy of the valve plate 26 during movement are further enhanced. The connecting holes 23 are annularly distributed on one side of the water passage opening 27 and there are as many as nine of them, improving the adaptability and flexibility of the valve to pipelines or other connectors. The design of the close sliding fit between the upper and lower ends of the two sliding plates 21 and the upper and lower inner walls of the valve housing 1 not only reduces the frictional resistance and ensures the smooth movement of the valve plate 26, but also further improves the sealing performance of the valve.

[0025] When installing or disassembling the valve, pass the mounting barrel 38 on one side of the mounting plate 30 through the reserved hole, and then drive the mounting screw 32 to rotate by rotating the knob 31. Under the action of the thread, the mounting screw 32 moves axially along the mounting barrel 38, and at the same time pushes the limit rod 33 and the limit card rod 34 to move together. When the limit card rod 34 slides into the limit card slot 37 on the outer surface of the mounting barrel 38, it reaches the predetermined fastening position. At this time, under the cooperative action of the limit bead 35 in the limit groove 36, the limit bead 35 is pushed out or disengaged by the limit rod 33 and the limit card rod 34, so that the limit bead 35 can be limited on the other side of the reserved hole to prevent it from loosening or falling off, realizing the quick installation and disassembly of the valve, and at the same time ensuring the stability and safety during the installation process.

[0026] By providing a limit groove 36 on the outer surface of the mounting barrel 38 and using it in conjunction with the limit bead 35, precise limitation of the mounting screw 32 and the limit rod 33 is achieved. The limit card slot 37 is ingeniously combined with the limit card rod 34, providing a reliable locking mechanism for the quick-release mechanism 3. By adding a knob 31 at one end of the mounting screw 32, a more convenient operation method is provided for the user.

[0027] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
