Daily height gate gate valve adopts double through hole blind plate, so that the gate valve plate can be rotated at a small Angle, as long as the rotation of 90°. The weight of the valve is symmetrical, there is no preference for imagination, and it can be rotated lightly. The operator can rotate the valve plate lightly by directly moving it.

The valve uses corrugated pipe instead of the old telescopic pipe device, the corrugated pipe is welded directly on the movable flange pipe and connecting flange pipe, in use without any adjustment, the structure is much simpler than the telescopic sleeve device.

The nut sleeve moves about 200mm along the axis of the screw. The screw can draw consistent to the end of the bellows and connecting flanges, so that the other end is separated from the valve plate. Under the condition of not removing the valve shell of the plug plate, it can also replace the gate plate and the gasket material, so as to facilitate maintenance.
