20120085427 Outlet Valve for a Frost-Preventing Faucet - An improved outlet valve for a frost-preventing faucet substantially employs an axial slot defined at a central top inside the inlet passage for being inserted by an elastic element and an axial post. A first stop ring is disposed around the stop valve. The first stop ring and the stop valve are inserted into a limiting slot of a hollow stop sleeve disposed under the stop valve. A second stop ring disposed around the stop sleeve is inserted into a lower section of an inner wall of the inlet passage. A bottom of the second stop ring is disposed above a top of the top porcelain. Cooperating the subject improved configuration with the top porcelain allows the water to be supplied upward since outlet gates of the bottom porcelain and the top porcelain stay abreast without a blockage. When a water pressure is larger than a rebounding force of the elastic element, the stop valve upwardly compresses the elastic element. Thereby, the water travels through the inlet passage disposed at the middle section of the plug and enters into an outlet hole at the top end of the tubular receiving valve seat. The water is further upwardly guided into a supplying pipe of the faucet. When the water pressure is smaller than the rebounding force of the elastic element, the elastic element compresses the stop valve. Thereby, an axial post of the stop valve is downwardly inserted into the limiting slot of the stop sleeve for impeding the water flow, so that the porcelain valve unit is prevented from freezing, and the water pressure is capable of controlling a feeding of the water flow.04-12-2012
