Double-seal eccentric-forged ball valve
By employing a double-seal design, utilizing the mutual attraction of magnets and locking blocks, along with the coordination of wire rope torsion springs, the problem of media leakage in existing eccentric forged ball valves is solved, achieving secondary sealing and improving the valve's sealing performance.

AI Technical Summary
Technical Problem
Existing eccentric forged ball valves lack secondary and double sealing structures, which may lead to media leakage after prolonged use and affect media transportation.
Method used
It adopts a double-sealed design, which realizes the switching of the card block between different slots through the mutual magnetic attraction between the magnet and the card block. Combined with the cooperation of steel wire rope and torsion spring, a secondary sealing effect is achieved.
Benefits of technology
It improves the sealing performance of the valve, ensuring that no media leakage occurs during long-term use and optimizes the shut-off effect.

Abstract
The application discloses a double-sealing eccentric forged ball valve, which comprises a side plate and a handle, a connecting pipe is fixedly installed on the side surface of the side plate, the side plate is symmetrically distributed about the center of the connecting pipe, a stopper is rotationally connected to the inside of the connecting pipe, a lap block is fixedly installed on the side surface of the connecting shaft, and a connecting plate is fixedly installed on the lower surface of the lap block. In the initial stage, the clamping block is located in the first clamping groove, and the stopper normally works. When the device needs to be closed, the connecting block is pulled first, the connecting block drives the clamping block to move out of the first clamping groove through the pull rope, then the staff can rotate the handle, the sliding block slides in the sliding groove, when the clamping block moves to the position of the second clamping groove, the clamping block enters the inside of the second clamping groove under the mutual magnetic force of the second magnet and the third magnet, at this time, the stopper has been rotated by 90 degrees, so that the device stops working.
