摘要： A minor water leak prevention apparatus for a water inlet valve, in which a float is mounted on a regulation bar and received in a water container. The water container is mounted on a siphon tube. The siphon tube is formed with an air aperture. A counterweight buoyance switch is mounted on the water container. The counterweight buoyance switch has a counterweight water compartment having a lower end forming a water drain hole. The counterweight water compartment has an upper end to which a closure pressing plate is mounted. The closure pressing plate is opposite to the air aperture. The counterweight buoyance switch controls opening/closing of the air aperture. This arrangement allows water ingress through a water inlet valve to be stopped when minor water leakage occurs in a water tank.

摘要： Disclosed is a water stop valve. A water inlet channel, a water outlet channel, and a water sealing surface are formed in a valve body. A valve stem has a middle portion movably disposed in the valve body and a lower portion mounted in a back-pressure hole of a water-plugging stopper. A back-pressure cavity is formed above the water-plugging stopper. A sealing end surface matching the back-pressure hole is formed on the valve stem. When in use, the valve stem drives the water plugging stopper to move downwards, the sealing end surface blocks the back-pressure hole, and the water plugging stopper blocks the water sealing surface, such that the water enters the back-pressure cavity, and the water pressure enables the water-plugging stopper to block the water sealing surface to stop the water. The water stop valve stops a water inlet valve from feeding in water in a timely manner.

摘要： Disclosed is a leak-proof device for a water inlet valve. A control valve is installed in a valve body for opening and closing a water inlet channel and a water outlet channel. An outer water tank and a leak-proof water tank are installed on the valve body. An inner water tank is disposed in the outer water tank, with the height of the inner water tank being lower than that of the outer water tank. The leak-proof water tank is in communication with the inner water tank via a water-passing channel A lever is pivotally connected to the valve body. Two ends of the lever are connected with an outer float and an inner float. The inner float is provided with a plug that is movable to block the water-passing channel. The leak-proof float is connected to the control valve.

摘要： An air release valve and an air pressure driven toilet water tank drain valve are provided. The air release valve includes a valve seat, a sliding block, and a push block. A bottom of the valve seat is provided with an air release channel, one end of the air release channel is an air inlet, and the other end of the air release channel forms an air release nozzle. The sliding block is located above the air release nozzle and is slidably arranged on the valve seat. The air pressure driven toilet water tank drain valve includes a drain valve body, an inner core tube, a limit device, a telescopic airbag, an air pump, the air release valve, a controller and an electronic induction switch. The air release valve with mechanical structure does not require power consumption and has low cost.

摘要： A major water leak prevention apparatus for a water inlet valve, in which a water receptacle tray is mounted on a water inlet valve body and includes an overflow port. The water receptacle tray has a bottom in which an opening is formed. A counterweight float is mounted on the water inlet valve body and includes a water compartment and a buoyance compartment arranged at a lower end of the water inlet valve body. The bottom opening of the water receptacle tray is connected via a passageway pipe to the counterweight float. The water compartment selectively blocks a lower end opening of the passageway pipe or opens the lower end opening of the passageway pipe. This arrangement helps stop water ingress through the water inlet valve when major water leakage occurs in a water tank.
