Technical Field

[0001] The present application relates to the field of valve technology, and in particular to a valve driving device. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems, and have functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems have a wide variety of varieties and specifications, from the simplest shut-off valves to various valves used in extremely complex automatic control systems. Most existing valves use a single method to drive the valve to close when in use, but the valve is prone to poor sealing after being used for a period of time.

[0019] When in use, the valve is installed through the flanges 2 on both sides. When the valve is used subsequently, the valve is driven to open and close through the driving mechanism 3. At the same time, the valve can be closed in two ways, thereby improving the safety of the valve.

[0020] Reference Figure 2-3 The driving mechanism 3 includes a threaded rod 4, which is rotatably connected to the valve body 1. A handwheel 5 is fixedly connected to the top of the threaded rod 4. A valve stem 6 is rotatably connected to the bottom of the valve body 1. The ends of the threaded rod 4 and the valve stem 6 extend into the interior of the valve body 1. A handle 7 is fixedly connected to the bottom of the valve stem 6. The ends of the threaded rod 4 and the valve stem 6 extend into the interior of the valve body 1. A partition 8 is fixedly connected to the interior of the valve body 1. The partition 8 is set in an L shape. The partition 8 blocks the flow of the fluid inside the valve body 1 to facilitate the subsequent driving of the valve to open and close. A groove 9 is provided on the partition 8. A plurality of flow ports 10 are provided inside the groove 9. A first baffle 11 is provided on the top of the groove 9. The first baffle 11 is fixedly connected to At the end of the threaded rod 4, it is convenient to drive the first baffle 11 to rotate through the threaded rod 4. The bottom of the first baffle 11 is fixedly connected with a sealing ring 12. The sealing ring 12 improves the sealing performance between the first baffle 11 and the groove 9. The bottom of the partition 8 is rotatably connected with a second baffle 13. The second baffle 13 is fixedly connected to the end of the valve stem 6. The second baffle 13 is arranged at the bottom of the groove 9. A plurality of through holes 14 are opened on the second baffle 13.

When the valve is opened, the threaded rod 4 is rotated by the hand wheel 5, and the first baffle 11 is driven to move by the threaded rod 4, so that the first baffle 11 is separated from the groove 9, and then the valve stem 6 is rotated by the handle 7, and the second baffle 13 is driven to rotate by the valve stem 6, so that the second baffle 13 is aligned with the multiple flow ports 10, so that the valve is opened, so that the fluid flows inside the valve, and when the valve is subsequently closed, the threaded rod 4 is rotated by the hand wheel 5, so that the threaded rod 4 drives the first baffle 11 to move, so that the first baffle 11 covers the top of the groove 9, and the multiple flow ports 10 are blocked by the first baffle 11, so that the valve is in a closed state; the valve stem 6 is rotated by the handle 7, so that the valve stem 6 drives the second baffle 13 to rotate, and at this time, the second baffle 13 blocks the multiple flow ports 10, blocking the flow of the fluid, thereby doubly closing the valve.
