Claims

[Scope of Claim for Utility Model Registration] A pressure release port communicating with the internal waterway of the water purifier is kept closed at all times by a valve body, and when the water pressure inside the water purifier exceeds a predetermined pressure, the valve body moves in the valve opening direction. In a safety valve for a water purifier that moves to release pressure, the valve body is held by a retainer, and a hollow water drainage chamber is formed between the valve body and the retainer,
The valve body has a passage that allows communication between the pressure release port and the water drain chamber when the valve is closed, while the retainer has a water drain port for draining water, and the water drain port is always open in the water drain chamber. A safety valve for water purifiers, which is characterized by having a water drain valve.
