摘要： A flush valve includes a valve housing defining a fluid passageway between a fluid inlet and a fluid outlet. The fluid passageway includes a diaphragm valve seat disposed between the fluid inlet and the fluid outlet. The flush valve additionally includes a diaphragm assembly including a diaphragm and a disc. The diaphragm includes a primary opening and a bypass opening. The primary opening receives the disc therein and the bypass opening allowing water under pressure supplied to the fluid inlet to pass from a fluid inlet side of the diaphragm into a chamber in the fluid passageway. The flush valve additionally includes a relief valve configured to selectively control fluid flow from the chamber to the fluid outlet. The relief valve comprises a stationary valve element and a rotatable valve element each having at least one opening and being rotationally positionable relative to one another to regulate fluid flow.

摘要： A flush toilet includes: a water supply channel that allows flush water to be supplied from a flush water storage tank to a rim spout port and a jet spout port; and a switching device that switches a water supply path so as to execute a first flushing process of spouting the flush water in the water supply channel from the rim spout port and after that, execute a second flushing process of spouting the flush water in the water supply channel from at least the jet spout port. The switching device includes a switching valve body that operates by receiving the water pressure of the flush water pressurized by a pressure pump. This switching valve body performs switching to a water supply path that allows the first flushing process or the second flushing process to be executed according to the water pressure generated by the pressure pump.

摘要： A method of controlling actuation of a flush apparatus includes the steps of configuring a control module to actuate the flush apparatus for completing a flushing cycle periodically; and after a given unused time period of the flush apparatus, enabling the control module to enter into a sleep mode to stop an actuation of the flush apparatus. Therefore, during the rush hours, the control module is configured to actuate the flush apparatus frequently and during the off rush hours, the control module is configured to actuate the flush apparatus seldom.

摘要： A flush valve system is provided having an inlet and an outlet, and a main valve element adapted for transition between a closed position and an open position is disclosed. The flush valve further includes a control chamber in communication with the inlet, and a vent outlet in communication with the outlet. The system includes a solenoid for establishing communication between the control chamber and the vent outlet to establish a pressure differential across a portion of the main valve element. The system also includes a power supply for energizing the solenoid, a deployable actuator in communication with the power supply, and a microprocessor in electrical communication with the main valve element. The microprocessor is adapted to determine a valve opening time, calculate fluid pressure based on the valve opening time, and deliver a predetermined quantity of fluid through the valve based on fluid pressure.

摘要： A flush system includes a meter valve, a first pipe, a vacuum breaker, a second pipe, and a ball valve assembly. The meter valve defines a selectively openable outlet. The first pipe is in fluid communication with the meter valve and a water supply source. The vacuum breaker is disposed within the first pipe upstream of the meter valve and oriented to prevent backflow from the meter valve to the water supply source. The second pipe extends from a wall and is downstream from the supply source. The ball valve assembly is disposed between the first pipe and the second pipe upstream of the vacuum breaker to facilitate fluid communication between the first pipe and the second pipe and to selectively isolate the meter valve from the water supply source.

摘要： A diaphragm type of flush valve for use with toilet devices such as urinals and water closets includes a body with an inlet and an outlet and there is a valve seat therebetween and a valve member movable to a closing position on the valve seat. The valve member includes a diaphragm which is peripherally attached to the body. There is a pressure chamber above the diaphragm for holding the valve member on its valve seat and there is a filter and a bypass orifice connecting the inlet and the pressure chamber. The filter includes a filter ring positioned beneath the diaphragm and adjacent the outer periphery thereof. The filter ring and the diaphragm are held in a fixed position relative to each other. The filter ring has a plurality of outwardly directed circumferentially spaced filter grooves. There is a seal ring between the filter ring and the body and facing the grooves. A peripheral chamber is bounded by the seal ring, the filter ring and the body, with water reaching the peripheral chamber by passing through the filter ring grooves. There is an orifice connecting the peripheral chamber and the pressure chamber.
