Abstract

The invention relates to a new valve, comprising valve body, valve board, sealing tape, valve bar, packing box, valve shell, U-shaped sealing ring, characterized in that at the two ends of the valve there is the match part of U-shaped sealing ring, one end is positive joint and the other is negative joint; valve board can open ultimately and rotate round a axis; when the board is open ultimately, the diameter of the channel of valve and the inlet pipe is the same and there is no barrier in the middle; there is sealing type between valve body and board; screw and packing box are used as closed parts. The valve with multiple usages, whose sealing is reliable, is not afraid of feculence, corrosion and sand.

Description

technical field [0001] The present invention relates to a novel valve. Background technique [0002] Commonly used valves are connected with cast iron or steel pipes with flanges. Most of the valves themselves are metal valves matched with valve seats, which are prone to corrosion, resulting in poor closure and leakage. Each valve has a single purpose and cannot be used universally. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned defect, and provide a kind of novel valve. [0004] The technical solution of the present invention is a new type of valve, which includes a valve body, a valve plate, a gasket, a valve stem, a stuffing box, a valve housing, and a U-shaped sealing ring. It is characterized in that: both ends of the valve are U-shaped seals. Ring kit, one end is a female joint, the other end is a male joint, the valve plate can be fully opened and rotated around the shaft, when fully open, the valve channel has...
