[0002] With the continuous improvement of urban water supply and drainage, gas transmission and municipal pipeline systems, valves, as core components for controlling fluid transmission, are directly related to the safe and efficient operation of the pipeline system due to their installation stability and operational reliability. Valve wells, as important installation carriers for valves, provide necessary protection and maintenance space for valves. Valve support devices, as key supporting structures inside valve wells, play an important role in fixing valve positions, distributing valve weight and buffering pipeline vibrations. Their performance directly affects the service life and operational safety of valves. Therefore, valve support devices for valve wells with stable structures and strong adaptability are needed to reliably support various types of valves.

[0003] However, the existing support devices make valve installation more complicated, which prolongs the valve installation period, increases the difficulty and labor intensity of construction personnel, and reduces the valve maintenance efficiency. Utility Model Content

[0019] A specific application of this embodiment is as follows: In use, the valve is placed between two fixed clamps 222, and the threaded rod 216 is rotated. The threaded rod 216 drives the rectangular plate 217 to slide downwards on the two slide rods 218. The two telescopic protective sleeves 2112 deform and adapt to the position of the rectangular plate 217. Under the action of the two transmission rods 2110 and the corresponding two slots 219, the rectangular plate 217 presses the two L-shaped drive rods 214 to rotate on the two cylindrical rods 213 respectively. The two L-shaped drive rods 214 push the two connecting rods 2111 closer to each other through the two slots 219 located above. The two connecting rods 2111 and the slide rail 221... With the cooperation of both, the two fixing clips 222 are brought closer together. The two fixing clips 222 fix the valve through the two anti-slip buffer pads 223 respectively. After fixing, the compression ring 312 is rotated. The compression ring 312 moves into the cylindrical cover 311 through the threaded groove 313, squeezing several elastic fixing blocks 321 closer together, causing them to deform and generate elastic force, thereby fixing the threaded rod 216. When it is necessary to release the fixing of the valve, the compression ring 312 is rotated in the opposite direction. At this time, the compression on the elastic fixing blocks 321 disappears, the elastic force is released, and they are reset. Then the threaded rod 216 is rotated in the opposite direction, which drives the two fixing clips 222 away from each other, and the valve is removed.
