Soft and dense mechanical triangular lock gate valve

Abstract

The utility model discloses a soft and dense mechanical triangular lock gate valve, which comprises a valve seat, a connecting pipe communicated with the outer wall of the valve seat, a valve cover arranged on the top surface of the valve seat, and a processing component arranged below the valve cover. The rotating valve rod pushes the flashboard downwards towards the valve seat through the frame body, the second magnetic ring and the sealing ring which are arranged in the flashboard in a sliding mode are made to move downwards along with the flashboard, and when the sealing ring is aligned to the valve seat, under the magnetic repulsion limitation of the second magnetic ring and the first magnetic ring, the second magnetic ring drives the sealing ring to slide towards the ferrule, the sealing ring and the ferrule are arranged in a sleeving mode, and therefore sealing is achieved. When the valve body needs to be opened, the sealing rod is pulled, and due to the fact that the sealing rod and the air pipe slide in a sealing mode and the air pipe is a soft pipe body, the sealing rod pumps air in the air pipe under the limitation of the sealing rod.
