Overflow type low-noise water inlet valve and method for realizing inlet water silence of anti-siphon water inlet valve
The invention relates to an overflow type low-noise water inlet valve and a method for realizing inlet water silence of an anti-siphon water inlet valve. The overflow type low-noise water inlet valve comprises a water inlet valve body and a water inlet pipeline. The water inlet pipeline is connected with the water inlet valve body and supplies water for the water inlet valve body. The water inlet valve body is provided with an atmosphere communicating opening at a position which is higher than the highest water level of the water inlet valve. The liquid level in the water inlet valve body is directly communicated with the atmosphere through the atmosphere communicating opening for realizing siphon prevention. The water outlet channel of the water inlet valve body comprises a main water path and a plurality of auxiliary water paths. The main water path is directly communicated with the water inlet channel of the water inlet valve body. The auxiliary water paths are communicated with the main water path. The water outlet flow of the main water path is smaller than the water inlet flow of the water inlet channel. Water current overflows from the main water path to the auxiliary water paths for performing auxiliary water discharging. The water inlet valve of the invention can satisfy a requirement that the noise of the water inlet valve in water incoming is smaller than 20db according to EN ISO3822 standard, and furthermore can satisfy a requirement for siphon prevention capability of the water inlet valve according to EN1717. Furthermore the overflow type low-noise water inlet valve has advantages of simple structure, convenient mounting and low cost.
