It is usually used in occasions that require interception and regulation, such as fluid control in pipeline systems, flow regulation in industrial equipment, etc. The gate in the gate valve is its core structure. The gate is a key component for controlling fluid flow, usually a rectangular or trapezoidal metal plate. Through manual or automatic operation, the gate can be moved up or down to open or close the valve.
[0003] In a traditional gate valve, the valve body (valve housing) is the main outer shell of the gate valve, which is used to fix and support other valve components. It usually has inlet and outlet threads for connecting pipes. The valve seat is located inside the valve body and is an important part of the valve seal. When the gate is closed, the valve seat contacts the gate to prevent the fluid from passing; when the gate is open, the fluid can pass through the space between the valve seat and the gate. The gate is one of the most critical components in the gate valve. It is a flat plate that can be moved up or down by manual operation to control the fluid flow in the pipeline. The gate is usually connected to the valve stem and can be moved up and down by rotating the valve stem.
[0004] However, the gate adjustment method in traditional gate valves is often direct translation. This movement method has a small opening range and cannot support a wider range of fluid flow regulation or adapt to a variety of flow control requirements, which reduces the applicability of this gate valve.

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a gate valve with manually adjustable movable gate plate seal, comprising a gate body 1, a bottom plate 2 is fixedly connected to the lower surface of the gate body 1, a manual valve 3 is fixedly connected to the bottom of the bottom plate 2, a pull-out rod 4 is fixedly connected to the output end of the manual valve 3, one end of the pull-out rod 4 is fixedly connected to a slide 6, a slide rail 5 is fixedly connected to the bottom of the bottom plate 2, the slide 6 is slidably connected inside the slide rail 5, a connecting shaft 7 is rotatably connected inside the slide 6, a plurality of turntables 9 are fixedly connected to the bottom of the bottom plate 2, a rotating plate 8 is rotatably connected to the side wall of the turntable 9, one end of the connecting shaft 7 is slidably connected inside the turntable 8, a rotating shaft 10 is fixedly connected to the side wall of the turntable 8, the rotating shaft 10 is rotatably connected between the plurality of turntables 9, a gate 11 is fixedly connected to the side wall of the rotating shaft 10, and a connecting component is arranged on the top of the gate body 1.
[0024] Specifically, by pressing the manual valve 3, the manual valve 3 can output a push-pull force to the pull rod 4, thereby pushing the slide 6. The slide 6 slides inside the slide rail 5 under the action of the force, and then the connecting shaft 7 inside the slide 6 starts to rotate and changes its inclination angle. The rotation of the connecting shaft 7 will drive the movement of the rotating plate 8, so that the rotating plate 8 rotates on the side wall of the turntable 9 and changes its own inclination angle. At the same time, as the turntable 9 rotates, the rotating shaft 10 on its side wall will also rotate synchronously. By rotating the rotating shaft 10 between the turntables 9, the gate 11 on the side wall of the rotating shaft 10 can be opened and closed relative to the flow port of the gate body 1. Such a structure replaces the translation gate valve with a rotary valve, because the rotary valve can generally provide a larger fluid control range, thereby supporting a wider range of fluid flow regulation needs. This design can provide more efficient and flexible operations in fluid control systems and is suitable for various industrial and commercial application scenarios.
[0025] Reference Figure 3 The connecting component includes a connecting platform 12, which is fixedly connected to the top of the gate body 1, a hydraulic rod 13 is fixedly connected inside the connecting platform 12, and a connecting platform 2 14 is fixedly connected to the output end of the hydraulic rod 13, and a connecting piece 15 is fixedly connected to the bottom of the connecting platform 2 14, and a plurality of fixing bolts 16 are threadedly connected inside the connecting piece 15, and a slide plate 17 is threadedly connected to the outer wall of the fixing bolt 16, and the slide plate 17 is slidably connected to the inside of the gate body 1, and a plurality of sliding shafts 19 are slidably connected inside the gate body 1, and a plurality of sliding grooves 18 are opened inside the slide plate 17, and the outer wall of the sliding shaft 19 is slidably connected inside the sliding groove 18, and a deflector plate 20 is fixedly connected to the bottom of each sliding shaft 19, and a plurality of arc grooves 21 are opened inside the deflector plate 20.
[0026] Specifically, the hydraulic rod 13 outputs a push-pull force to the connecting platform 2 14 through the fixed position of the connecting platform 1 12. Once the connecting platform 2 14 is acted upon by a force, it will be displaced and will drive the connecting member 15 at the bottom to move synchronously. The connecting member 15 is connected to the slide plate 17 through the fixing bolt 16, thereby transmitting the motion to the slide plate 17. In this way, the slide plate 17 can slide inside the gate body 1. The sliding of the slide plate 17 produces a push-pull effect on the outer wall of the slide shaft 19 through the slide groove 18. This push-pull effect causes the slide shaft 19 to be displaced through the slot hole of the slide groove 18 inside the gate body 1. At the same time, the movement of the slide shaft 19 will also drive the deflector plate 20 at its bottom to be displaced synchronously. The flow rate of the fluid can be regulated by the arc groove 21 set on the deflector plate 20. This design ensures the applicability of the gate valve in different scenarios and improves its flexibility and functionality. Such a system can meet various fluid control requirements and ensure that the fluid flow rate is accurately controlled, thereby improving the efficiency and safety of the industrial production process.
[0027] Working principle: when the gate body 1 needs to be opened and closed by the rotating shaft 10, the manual valve 3 is pressed first. The manual valve 3 can output a push-pull force to the pull rod 4 to push the slide 6. After the slide 6 is subjected to the force, it slides inside the slide rail 5. At this time, the connecting shaft 7 inside the slide 6 rotates and changes its inclination angle. The rotation of the connecting shaft 7 can pull the rotating plate 8, so that the rotating plate 8 rotates on the side wall of the turntable 9 and changes its own inclination angle. When the turntable 9 rotates, the rotating shaft 10 of its side wall can be driven to rotate synchronously. The rotation of the rotating shaft 10 between the turntables 9 can realize the opening and closing of the gate 11 on the side wall of the rotating shaft 10 relative to the flow port of the gate body 1. In this way, the structure is replaced by a translation gate valve with a rotary valve. The rotary valve can usually provide a larger fluid control range, thereby supporting a wider range of fluid flow regulation. When it is necessary to control the fluid flow rate inside the gate body 1, the hydraulic rod 13 is started. The hydraulic rod 13 outputs a push-pull force to the connecting platform 2 14 under the fixation of the connecting platform 1 12. After the connecting platform 2 14 is subjected to the force, it can be displaced and drive the connecting member 15 at its bottom to be displaced synchronously. At this time, the connecting member 15 is connected to the sliding plate 17 through the fixing bolt 16, which transmits the transmission to the sliding plate 17 through the connection with the sliding plate 17, so that the sliding plate 17 can slide inside the gate body 1. The sliding of the sliding plate 17 can be pushed and pulled on the outer wall of the sliding shaft 19 through the sliding groove 18, so that the sliding shaft 19 is displaced inside the gate body 1 through the groove hole direction of the sliding groove 18. When the sliding shaft 19 is displaced, the deflector plate 20 at its bottom is driven to be displaced synchronously and the fluid flow rate is adjusted through the setting of the arc groove 21, which ensures that the gate valve can adapt to different scenarios when used and improves flexibility.
