Abstract
The utility model discloses a corrugated pipe type static balance valve, and belongs to a valve structure applied to the technical field of water supply and drainage. The valve comprises a valve body, a valve flap, a valve base, a valve rod, a valve cover and a hand wheel. The valve is characterized in that a connected shaft sleeve at the upper end of the valve flap is sleeved with a corrugated pipe, and the two ends of the corrugated pipe are connected with the valve body and the valve flap respectively in a sealed mode. The structure where the corrugated pipe is additionally arranged enables medium pressure at the upper end of the valve flap and medium pressure at the lower end of the valve flap to be balanced so that opening and closing torque of the valve can be effectively reduced, and the problem that the valve is difficult to open and close or fails in opening and closing due to the fact that action force of media on the valve flap is too large in the opening and closing processes of the valve is solved. Meanwhile, an adjusting ring is arranged in the inlet end of the valve body, and the number of turns for adjusting can be determined in debugging of the valve according to flow resistance coefficient at the front end and at the rear end of the adjusting ring. Accordingly, the improved static balance valve has the advantages of being compact in structure, small in size, reliable in quality and low in production cost, saving labor in opening and closing and the like.
