More Information
Summary:The utility model relates to a leakage-proof valve, comprising a valve body, a valve rod, and a valve core matching with the valve port on the valve body, among which the valve rod forms rotary connection within the valve body, with one end thereof hinged with one end of a link rod and the other end connected with a internal permanent magnet in the valve body-among which the other end of the link rod is also hinged with the valve core and an actuating mechanism interlocked with the internal permanent magnet is positioned outside the valve body. Such leakage-proof valve as presented in the utility model has completely avoided leakage from the gap between the valve rod and the valve body and thereby lengthened the valve life, for actually no gap therebetween exists due to the fact that the other end of the valve rod -as above mentioned-is connected with the internal permanent magnet that is wholly positioned within the valve body instead of passing therethrough and any action of the valve rod is fulfilled with the aid of the actuating mechanism outside the valve body.
