Description

Water outlet valve Technical Field The invention relates to the technical field of valves, in particular to a water outlet valve. Background The wall-mounted boiler waterway system is a water heater taking natural gas as an energy source, has a powerful home central heating function, can meet the heating requirements of multiple rooms, and can provide domestic water for places such as home bath, kitchen and the like. The wall-mounted boiler waterway system in the related art generally comprises a combustion chamber, a heat exchange structure, a water inlet valve and a water outlet valve, wherein the combustion chamber is generally arranged on a wall in a room, the water inlet valve can provide water for the combustion chamber, the heat exchange structure comprises a heat exchange channel and a water supply channel which are matched with each other through heat exchange, the water outlet valve comprises a valve body and a switching device, a hot water inlet, a heating water outlet interface, a bathroom water outlet interface, a heat exchange water inlet interface and a heat exchange water outlet interface are arranged on the valve body, the hot water inlet is communicated with an outlet of the combustion chamber, the heat exchange water inlet interface is communicated with an inlet of the heat exchange channel, the heat exchange water outlet interface is communicated with an outlet of the water supply channel, water in the water supply channel can flow to the bathroom water outlet interface through the heat exchange water outlet interface after heat exchange is carried out on the heat exchange channel, so as to provide bathroom hot water for a user, and the hot water inlet is switched through the switching device so as to be selectively communicated with the heating water outlet interface or the heat exchange water inlet interface.
