Abstract
A flush valve has a valve body, a relief assembly, and a solenoid valve assembly. The valve body has a flushing tube. The solenoid valve assembly has a seal, an assembling mount, a solenoid valve, and a power supply. The seal is disposed between a diaphragm of the relief assembly and an intake end of the flushing tube. The assembling mount has a disk. A first reserving space is formed between the disk and the relief assembly. The solenoid valve is assembled to the assembling mount. A second reserving space is formed between the solenoid valve and the assembling mount and communicates with the first reserving space. The solenoid valve has a blocking unit to prevent the first reserving space and the second reserving space from communicating with each other. The power supply is electrically connected to the solenoid valve.
