Abstract:
A valve structure, comprising a valve cavity (53), a valve member (54), a valve shaft opening (58) and a shaft (59) corresponding to the chamber (53), a water or gas inlet pipe (55), a water or gas outlet pipe, a connecting rod (52), a horizontal rod, and a coil spring. The valve member (54) is installed within the cavity (53). The valve member (54) is provided with the valve shaft opening (58). One end of the connecting rod (52) is connected to the valve member (54), and a top portion of the other end of the connecting rod passes through the cavity (53) and is connected to the horizontal rod. A bottom end or a top end of a time delay valve communicates with the water or gas inlet pipe (55), and a top end or a bottom end of an inner surface of the time delay valve cavity is fixedly connected to the shaft (59). The entirety or part of the shaft (59) is placed within the valve shaft opening (58). The valve shaft opening (58) forms a clearance fit with the shaft (59). The water or gas outlet pipe is situated on a side surface of the time delay valve. When the time delay valve is not moving, the valve member (54) is positioned at a bottom portion of the time delay valve.
