Dual plate check valve relies on the flow of the medium itself to automatically open and close the valve disc to prevent the backflow of the medium and the hammer effect of water; the two valve plate rotate around the middle valve shaft, like two sliding doors, and are equipped with springs , pushing the two valve discs to move in the direction of valve closing; the butterfly check valve has a simple structure and can only be installed on horizontal pipes, and its sealing performance is relatively poor, and its sealing performance requirements are not high during use; it is suitable for cities , industrial and high-rise building water supply and drainage pipe networks, the structural length is shorter than the swing check valve, and the installation is more convenient.
