[0028] The following will describe the implementation of this utility model in detail with reference to specific embodiments, so that the process of how this utility model uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0029] Example

[0030] like Figures 1 to 4 As shown, an easily detachable clamp-type exposed stem soft-seal gate valve includes a valve body 1 and a valve cover 2 disposed on the valve body 1. The valve body 1 has connection ports 11 on both sides, and a flange 3 is provided at each connection port 11. An installation component 4 is provided on one of the flanges 3. A ramp 31 is provided on the side of the flange 3 near the valve body 1. The ramp 31 is arc-shaped along the edge of the flange 3. The height of the ramp 31 gradually increases from one end to the other end. The lowest point of the ramp 31 is flush with the flange 3. Three grooves 32 are provided on the ramp 31. The installation component 4 includes two U-shaped buckles 41. One end of each U-shaped buckle 41 is provided with a rotating ball 5 that matches the groove 32.

[0031] Let the radius of the rotating ball 5 be r, and the spacing between each groove 32 be r; each groove 32 is circular, and the diameter of each groove is 0.3r.

[0032] Each of the connection ports 11 protrudes from each of the flanges 3, and each of the connection ports 11 is provided with a sealing ring 6 on its outer side, the sealing ring 6 being made of rubber.

[0033] A bracket 7 is provided above the valve cover 2, and a turntable 71 is provided above the bracket 7. A rotating rod 72 is provided inside the bracket 7. The top of the rotating rod 72 is connected to the turntable 71. A valve plate 12 is provided inside the valve body 1. The bottom of the rotating rod 72 passes through the valve cover 2 and is connected to the valve plate 12. A mounting hole 121 is provided on the valve plate 12. An opening 122 is provided at the top of the mounting hole 121. A limiting block 721 is provided at the bottom of the rotating rod 72. The limiting block 721 is located inside the mounting hole 121.

[0034] The turntable 71 and the rotating rod 72 are threaded together. In use, rotating the turntable 71 drives the rotating rod 72 to rotate. Under the threaded drive, the rotating rod 72 rises upward, causing the valve plate 12 to rise and thus opening the gate valve. The design of the limit block 721 and the mounting hole 121 allows the rotating rod 72 to be manufactured separately from the valve plate 12. At the same time, no additional connection steps are required during assembly. Simply place the limit block 721 on the side of the mounting hole 121 into the mounting hole 121 to drive the valve plate 12 with the rotating rod 72.

[0035] At least four bolt holes 33 are arranged on each flange plate 3, and the mounting assembly 4 is arranged between the intervals of the bolt holes 33; this design makes the mounting assembly not affect the locking of the bolts during installation.

[0036] Principle of use:

[0037] During installation, first connect one side of the valve body 1 with the pipeline, then arrange the end of the U-shaped buckle 41 with the rotating ball 5 at the lowest point of the inclined table 31 arranged on the flange plate 3, and gradually move the U-shaped buckle 41 along the edge of the flange plate 3 to the direction of increasing height of the inclined table 31, so as to limit the distance between the other side of the gate valve and the pipeline.

[0038] Although the utility model is specifically shown and introduced in combination with the preferred embodiments, it should be understood by those skilled in the art that various changes can be made to the utility model in form and details without departing from the spirit and scope of the utility model defined in the appended claims, and all of them are within the protection scope of the utility model.
