Abstract
The utility model discloses a light flap valve without pin, comprising a valve body. The valve body is internally provided with a valve seat. The valve seat is internally provided with a valve board. The bottom of the valve body is provided with a bottom cover. The upper flange which is arranged on the upper part of the valve body and is used for connecting with handle or worm wheel gear is a round flange or a square flange. A revolving shaft which is used for controlling the movement of the valve board inside the valve body and for connecting with the valve board divides to an upper revolving shaft which is positioned on the inner upper part of the valve body and a lower revolving shaft which is positioned on the inner lower part of the valve body. The lateral flange of the valve body takes a round arc structure which can be connected with various standard tube flanges. With adoption of the above structure, the utility model has the advantages of convenient operation, raw materials conservation, flexible unloading of the valve board, safely sealing and no leakage. The valve body of the utility model can be connected with various standard rube flanges. The upper flange which is arranged on the valve body is suitable to the International Standard and the American Standard. The utility model is applied to the piping system in projects such as Petrochemical, medical, food, light industry, paper making, power generation, city water supply and drainage, coal gas, heating and metallurgy.
