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.

In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.

[0021] Reference Figures 1 to 5 In an embodiment of the utility model, a soft-sealed gate valve that is easy to replace a sealing ring includes: a valve body 1, a valve stem 4 and a hand wheel 5. An annular block 2 for connecting a pipeline is fixedly connected to one end of the side of the valve body 1. A sealing ring 6 for sealing the pipeline is arranged on the inner wall of the annular block 2. A locking mechanism 3 for increasing the sealing effect of the sealing ring 6 is arranged at one end of the side of the annular block 2.

[0022] With the above solution, the sealing ring 6 can be squeezed by the locking mechanism 3 to achieve better sealing. The locking mechanism 3 also facilitates the disassembly and replacement of the sealing ring 6 .

[0023] The locking mechanism 3 includes an extrusion mechanism 31 slidably connected to one end of the side of the annular block 2 for extruding the sealing ring 6 , and a rotating rod 32 for adjusting the position of the extrusion mechanism 31 is screwed to one end of the side of the extrusion mechanism 31 .

[0024] The extrusion mechanism 31 includes a connecting block 313 screwed on one end of the side of the rotating rod 32, a threaded hole 314 is opened on one end of the side of the connecting block 313, an extrusion block 312 is fixedly connected to one end of the side of the connecting block 313, a limiting block 311 is fixedly connected to one end of the side of the extrusion block 312, and a slider 315 is fixedly connected to one end of the side of the extrusion block 312.

[0025] The rotating rod 32 includes a threaded rod 321 screwed to one end of the side of the extrusion mechanism 31 , a knob 322 is fixedly connected to one end of the side of the threaded rod 321 , and a limit plate 323 is fixedly connected to one end of the side of the threaded rod 321 .

[0026] The above scheme is adopted: by turning the knob 322, the threaded rod 321 is driven to rotate on the side of the connecting plate 22, thereby driving the extrusion mechanism 31 to slide on the side of the fixed plate 23 toward the side of the valve body 1, and the sealing ring 6 is squeezed by the slope on the side of the extrusion block 312, so as to be more sealed. The slider 315 is T-shaped and can limit the extrusion mechanism 31. The limit plate 323 can prevent the extrusion mechanism 31 from detaching during rotation. When the sealing ring 6 needs to be replaced, the threaded rod 321 is driven to rotate in the opposite direction by turning the knob 322 in the opposite direction, thereby driving the extrusion mechanism 31 to move toward the outside of the valve body 1, so that the sealing ring 6 is relaxed, and the sealing ring 6 can be taken out at this time.

[0027] The annular block 2 includes an annular block body 21 fixedly connected to one end of the side of the valve body 1 , a connecting plate 22 fixedly connected to one end of the side of the annular block body 21 , and a fixing plate 23 fixedly connected to one end of the side of the annular block body 21 .

[0028] A groove matching the locking mechanism 3 is formed at one end of the side surface of the annular block 2 .

[0029] The threaded hole 314 is matched with the rotating rod 32 .

[0030] The working principle of the utility model is as follows: first, the sealing ring 6 is placed on the inner wall of the annular block 2, and then connected to the pipeline, and the threaded rod 321 is driven to rotate on the side of the connecting plate 22 by turning the knob 322, thereby driving the extrusion mechanism 31 to slide on the side of the fixed plate 23 toward the side of the valve body 1, and the sealing ring 6 is squeezed by the slope on the side of the extrusion block 312, so as to be more sealed, and the slider 315 is T-shaped and can limit the extrusion mechanism 31, and the limit plate 323 can prevent the extrusion mechanism 31 from disengaging during rotation. When the sealing ring 6 needs to be replaced, the threaded rod 321 is driven to rotate in the opposite direction by turning the knob 322 in the opposite direction, thereby driving the extrusion mechanism 31 to move to the outside of the valve body 1, so that the sealing ring 6 is in a relaxed state, and the sealing ring 6 can be taken out at this time, which is simple to operate and more convenient to disassemble and replace.

[0031] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
