[0002] A gate valve is a disc that opens and closes the flow. The disc's movement is perpendicular to the flow direction. A gate valve can only be fully opened or closed, and cannot be adjusted or throttled. A gate valve seals through contact between the valve seat and the disc. The sealing surface is typically welded with metal materials such as 1Cr13, STL6, or stainless steel to increase wear resistance. There are two types of discs: rigid and flexible. Depending on the type of disc, gate valves are classified as either rigid or flexible.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5 , the utility model provides an embodiment: a gate valve that is easy to maintain, including a gate valve body 1, a fixing structure 2 and a rubber ring 3, the fixing structure 2 is provided with four, the fixing structure 2 includes a hinge 21, the left and right ends of the gate valve body 1 are fixedly connected to one end of the two hinges 21, the other end of the hinge 21 is fixedly connected to the fixing plate 1 22, the fixing plate 1 22 is fixedly connected to the fixing plate 2 24, the right end of the fixing plate 2 24 is rotatably connected to the rotating rod 27, the right side of the fixing plate 1 22 is fixedly connected to the two limiting rods 211, the two limiting rods 211 are slidably connected to the splint 29, the outer wall of the splint 29 is fixedly connected to the extrusion plate 210, the right side of the two limiting rods 211 is fixedly connected to the limiting plate 212, and the left and right ends of the gate valve body 1 are fixedly connected to the rubber ring 3.

[0023] Furthermore, the rear side of the fixed plate 22 is fixedly connected to the clamping plate 23, and the rear end of the clamping plate 23 is provided with a certain curvature. Through the curvature set by the clamping plate 23, when the fixed plate 22 rotates, the clamping plate 23 will not collide with the gate valve body 1 and cause deformation.

[0024] Furthermore, the right side of the second fixing plate 24 is fixedly connected to two fixing seats 25 , the fixing seats 25 are rotatably connected to the rotating shaft 26 , and the rotating shaft 26 is rotatably connected to the left end of the rotating rod 27 , so that the rotating rod 27 can rotate through the fixing seats 25 and the rotating shaft 26 .

[0025] Furthermore, the left side of the rotating rod 27 is fixedly connected to the rubber head 28, and the rubber head 28 rests on the surface of the extrusion plate 210. The rotating rod 27 rotates from the vertical direction to the horizontal direction, and the rubber head 28 squeezes the extrusion plate 210, causing the second splint 29 to move toward the side close to the first splint 23.

[0026] Furthermore, a tension spring 214 is sleeved on the limit rod 211, one end of the tension spring 214 is fixedly connected to the limit plate 212, and the other end of the tension spring 214 is fixedly connected to the second clamping plate 29. When installed, the tension spring 214 is stretched by the tension, and when disassembled, the elastic force of the tension spring 214 pulls the second clamping plate 29 to reset.

[0027] Furthermore, the front side of the limiting plate 212 is fixedly connected to the buckle 213 , and the buckle 213 is engaged with the rotating rod 27 . The buckle 213 is a common C-shaped buckle, generally made of plastic or nylon, and has a certain degree of elasticity.

[0028] Furthermore, groove 1 11 and groove 2 12 are provided on the left and right sides of the gate valve body 1. The inner wall of groove 11 is fixedly connected to the rubber ring 31, and the rubber ring 31 is fixedly connected to the rubber ring 3. The diameter of groove 2 12 is larger than the diameter of the rubber ring 3. Groove 1 11 provides deformation space for the rubber ring 3. When the rubber ring 3 is squeezed, it can fill the groove 11.

[0029] Working principle:

[0030] When in use, place the pipeline against the left and right sides of the gate valve body 1, rotate the fixing plate 1 22 from the vertical direction to the horizontal direction, and the fixing plate 1 22 is rotated by the hinge 21. At this time, the clamping plate 1 23 is against the outer wall of the gate valve body 1, hold the handle of the rotating rod 27, and rotate the rotating rod 27 to rotate the rotating rod 27 from the vertical direction to the horizontal direction. The rubber head 28 squeezes the squeezing plate 210 to move the clamping plate 29 to the side close to the clamping plate 1 23. The tension spring 214 is stretched by the tension, and the clamping plate 1 23 and the clamping plate 29 fix the gate valve body 1 and the pipeline. The rotating rod 27 is clamped at the buckle 213 to complete the fixation. When the gate valve body 1 needs to be repaired, pull the rotating rod 27 to make the buckle 2 13 no longer clamps the rotating rod 27. At this time, the clamping plate 1 23 and the clamping plate 2 29 no longer clamp the gate valve body 1 and the pipeline. At this time, the gate valve body 1 can be disassembled. The gate valve body 1 can be quickly installed and disassembled through the fixing structure 2. The operation is convenient and fast, easy to use, and can be disassembled without tools, which improves the disassembly efficiency and facilitates maintenance personnel to repair the gate valve body 1. The pipeline squeezes the rubber ring 3, and the rubber ring 3 is squeezed and deformed. The groove 11 provides a deformation space for the rubber ring 3, so that the rubber ring 3 becomes flat, thereby filling the groove 11. The connection between the gate valve body 1 and the pipeline can be sealed by the rubber ring 3, thereby improving the sealing of the connection and improving the safety of use.
