1. A toilet inlet valve, comprising a valve body, an inlet pipe, a water stop device with a water stop rubber gasket, a float bowl device, a raising rod device and an outlet pipe, wherein, the water stop device also comprises:
a water stop seat, which is located at a front end of the outlet pipe, and of which an opening is coupling with an end face of the water stop rubber gasket; a tray, which is connected to the water stop rubber gasket, and is located at a side of the water stop rubber gasket that is opposite to the water stop seat; a needle valve, which is fixed to the tray, and is located at a side of the tray that is opposite to the water stop rubber gasket; a back pressure cavity, which is a cavity with a discharge hole, containing the tray and the needle valve, and is provided with a needle valve hole sleeved around the needle valve; water is divided into two ways by an inlet pipe valve body, one way is a dry way, and another way is a control branch; the dry way: water in this way enters a fluid cavity of the inlet pipe, and reaches the water stop rubber gasket, and then a reverse water pressure is generated, in an opposite direction to a water flow direction in the inlet pipe; the control branch: water in this way passes through a gap between the needle valve and the needle valve hole, and then reaches the back pressure cavity containing a needle valve cover, and then a downstream water pressure to the tray is generated, in a same direction as the water flow direction in the inlet pipe. |
