When the valve is closed, the hand wheel 1 rotates anticlockwise, the upper valve rod 2 moves downwards due to the rotation acting force of the hand wheel 1 and the spring force of the spring 13, the lower valve rod 10 is driven to move downwards, the middle elastic foldable structure 72 expands downwards after the sealing gasket 7 is stressed, and the valve is closed.
Wherein, the first hard sealing conical surface 84 on the valve body 8 is contacted with the sealing gasket 7 made of elastic material, and the sealing points are combined with each other in a soft and hard way, so that the sealing performance is better.
The hand wheel 1 and the upper valve rod 2 are connected through round threads, so that the rotation is smoother, and the swing force is smaller.
The elastic foldable structure 72 in the middle of the sealing gasket 7 has a self-correcting function, and can better fit with the first sealing conical surface 84 when being pressed downwards, so that the sealing effect of the valve is greatly improved.
The present utility model has been described above by way of example, but the present utility model is not limited to the above-described embodiments, and any modifications or variations based on the present utility model fall within the scope of the present utility model.
