Problems solved by technology

[0003] However, there is a problem with the plate heat exchange wall-hung boiler: heating and bathing cannot work at the same time. The general design is that bathing takes precedence over heating. When there is a water flow signal at the outlet of the bathing water, the heating end will stop heating.
For a wall-hung boiler with an instant heating function, it takes 10 minutes for the first instant heating of a 36-meter circulation pipe, and for longer circulation pipes and in the case of poor insulation facilities, the required time will be longer
During this period, heating will be stopped, which will cause uncomfortable experience for users

Abstract

The invention discloses a three-way valve. The three-way valve comprises a valve body, a water inlet, a first water outlet, a second water outlet, a moving shaft and a stepping motor, wherein the water inlet, the first water outlet, the second water outlet, the moving shaft and the stepping motor are arranged on the valve body; a water inlet cavity communicating with the water inlet is formed in the vale body; the first water outlet and the second water outlet separately communicate with the water inlet cavity through a first channel and a second channel which are coaxially arranged; and the moving shaft is arranged on the axes of the first channel and the second channel, a first water tray and a second water tray are fixed to the moving shaft, the first water tray and the second water tray separately correspond to the first channel and the second channel, and can separately seal the first channel and the second channel along with the movement of the moving shaft. When the first watertray seals the first channel, the second channel is opened, and when the second water tray seals the second channel, the first channel is opened, and three states of single-pass and double-pass are achieved. The invention further provides a plate exchange type gas wall-mounted furnace.

Description

technical field [0001] The invention relates to the technical field of fluid heaters, in particular to a three-way valve and a plate exchange gas wall-hung boiler with the three-way valve. Background technique [0002] At present, most of the wall-hung boilers on the market are dual-purpose wall-hung boilers, which can be used for both heating and bathing. At present, the plate heat-exchange wall-hung boiler is the most popular in the market and home. The principle is to install an electric three-way valve at the heating outlet of the wall-hung boiler, one end flows to the heating pipe, and the other end is connected to the plate heat exchanger. Exchange heat with bath water to generate hot water for bathing. [0003] However, there is a problem with the plate-exchange heat-exchanging wall-hung boiler: heating and bathing cannot work at the same time. The general design is that bathing takes precedence over heating. When there is a water flow signal at the outlet of the bat...
