Low-noise water inlet valve and method for achieving silence of anti-siphon water inlet valve during water feeding
The invention relates to a low-noise water inlet valve. The low-noise water inlet valve comprises a water inlet valve body, a lower sleeve and an upper sleeve. The lower sleeve is connected with a water inlet valve body and supplies water to the water inlet valve body. The upper sleeve is arranged between the water inlet valve body and the lower sleeve in a sleeved mode. The water inlet valve body, the lower sleeve and the upper sleeve jointly form a water outlet pipe. The water inlet valve body is provided with an atmosphere port which is located at the position higher than the highest water level. The liquid surface in the water inlet valve is directly communicated with the atmosphere through the atmosphere port, so that siphon is prevented. A water outlet channel of the water inlet valve comprises a main water way and multiple auxiliary water ways, the main water way is directly communicated with the water inlet channel, the auxiliary water ways are communicated with the main water way, the water outlet speed of the main water way is smaller than the water inlet speed of the water inlet channel, and water overflows to the auxiliary water ways from the main water way, so that water discharge is assisted. By the adoption of the low-noise water inlet valve, in the water inlet process of the water inlet valve, the suction sound is lower, water feeding of the water inlet valve is free of noise, the EN ISO3822 requirement that the noise is lower than 20 db when the water inlet valve feeds water can be met, and the anti-siphon requirement of EN1717 for the water inlet valve can also be met.
