Description

Technical Field

[0001] This utility model belongs to the field of antifreeze valve technology, specifically relating to a multi-functional antifreeze safety valve. Background Technology

[0002] Three-way valves, serving as the central connection between various pipelines, have a wide range of applications. For example, they are used in heat pump water heaters. Currently, existing three-way valves typically include a valve seat and a valve core located within the valve seat. The valve body has three ports, two of which are inlets and one is an outlet. Water flowing in from the two inlets mixes and flows out from the outlet.

[0003] However, when three-way valves are used outdoors in winter, they are prone to freezing, which can cause the valve core to freeze and become unable to rotate. This prevents the flow direction and opening / closing of the three-way valve from being controlled, thus causing inconvenience to production and daily life. Utility Model Content
