Description

Water outlet valve Technical Field The utility model relates to the technical field of valve elements, 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 water outlet valve is an indispensable structure in a wall-mounted boiler water path system, and mainly controls the water inlet and outlet opening and the water outlet diversion and the water flow direction and flow rate, so that the uniform conveying of hot water in a pipeline and the normal heating of a radiator are ensured. As shown in fig. 1, the three-way valve cavity 110 'of the outlet valve in the related art and the heating channel 120' are coaxially arranged, and the axial direction of the three-way valve cavity 110 'extends along the up-down direction during installation, and a driving motor is required to be installed at the top of the three-way valve cavity 110', so that the size of the whole outlet valve in the height direction is larger, and the installation height of the whole wall-mounted boiler water channel system is higher, and the volume is larger, so that the miniaturization requirement of the market on the wall-mounted boiler water channel system cannot be met. In addition, the bypass valve portion 12 'is further arranged beside the three-way valve portion 11' of the water outlet valve, a bypass cavity for installing the one-way valve 20 'is formed in the bypass valve portion 12', one end of the bypass cavity is communicated with the heating channel 120', the other end of the bypass cavity is communicated with the heat exchange flow channel through the three-way valve cavity 110', and when the one-way valve 20 'is opened, water in the heating channel 120' can be supplemented into the heat exchange structure through the bypass cavity and the heat exchange flow channel. However, the height of the outlet side of the check valve 20' is slightly higher than the height of the connection port between the bypass cavity and the three-way valve cavity 110', so that when the check valve 20' is opened, as shown by the arrow direction in fig. 1, after the water in the heating channel 120' flows from the inlet side of the check valve 20' to the outlet side thereof, the water on the outlet side flows into the three-way valve cavity 110' in a downward direction, which results in a "backflow" phenomenon of part of the water flow, and further results in a larger full-open flow loss of the check valve 20' and affects the water replenishing efficiency when the outlet valve is actually operated. Therefore, there is a need to provide a water outlet valve to solve the above problems. Disclosure of utility model The present utility model aims to solve or at least alleviate some or all of the above problems. Therefore, the utility model aims to provide the water outlet valve, which can greatly reduce the size of the three-way valve in the height direction so as to meet the miniaturization requirement of the whole wall-mounted boiler water path system, and can reduce the full-open flow loss of the one-way valve and improve the water supplementing efficiency.
