Embodiment 1
[0022] Embodiment 1 (for medium caliber glasses valve):
[0023] Embodiment 1 shown in Figures 1 and 2 is an automatic compensation clamping and sealing device used in glasses valves with medium caliber (pipe diameter φ1000-2400mm), which consists of a built-in automatic compensation clamping mechanism and a power mechanism that performs the function of pulling apart 7. Composed of pull rods 5; the built-in automatic compensation clamping mechanism is composed of clamping springs 6 biased on both sides of the longitudinal axis of the pipeline. The number of clamping springs 6 is 8, and the clamping springs 6 take the longitudinal axis of the pipeline as the symmetrical axis Symmetrical distribution; one end of the clamping spring 6 is in contact with the side wall of the movable valve seat pull plate 9, and the other end of the clamping spring 6 is in contact with the inner side wall of the valve body 1; the power mechanism 7 that performs the function of pulling apart is insta...
Embodiment 2
[0033] Embodiment 2 (for small-diameter glasses valve, the pipe diameter is φ600-700mm):
[0034] The difference between embodiment 2 and embodiment 1 is that the number of pull rods 5 is 2, and the number of clamping springs 6 is 2-4.
Embodiment 3
[0035] Embodiment 3 (for large-diameter glasses valve, the pipe diameter is φ2600-4000mm):
[0036] The difference between embodiment 3 and embodiment 1 is that the number of pull rods 5 is 8, and the number of clamping springs is 16-20.
