The invention relates to a water mixing prevention pipe valve device suitable for a water heater. The water mixing prevention pipe valve device comprises an outer pipe, an inner pipe, a valve plate device and a pressurizing hot water flow stopping device, wherein the inner pipe is sleeved with the outer pipe, the valve plate device is arranged in the outer pipe in a sliding mode, the outer pipe comprises a first opening and a second opening, the pressurizing hot water flow stopping device is arranged in the outer pipe, and opening and closing of the pressurizing hot water flow stopping device are controlled through sliding of the valve plate device; the valve plate device comprises a one-way valve plate and a valve plate first control spring, one end of the valve plate first control spring is connected with the pipe wall of the outer pipe, and the other end of the valve plate first control spring is connected with one side of the one-way valve plate. According to the water mixing prevention pipe valve device suitable for a water heater, the problem that hot water in a pressurized hot water pipeline flows into a cold water pipeline is solved through mutual sliding of the valve plate device and the pressurizing hot water flow stopping device under the action of water flow, use is convenient, and the application effect of saving more energy can be achieved.
Description
technical field [0001] The invention relates to the technical field of water heaters and domestic hot water pipeline circulation, in particular to a pipe valve device suitable for water heaters to prevent water crossing. Background technique [0002] In the prior art, when the zero-cold water heater with hot water pressurization function is installed and used in a water environment without pre-installed hot water return pipeline, the most common method is to use an "H-type cold and hot water pipe" in the prior art. Connector" is used in combination with the zero cold water water heater, and this "H type cold and hot water pipe connector" consists of a horizontal pipe with a check valve of the prior art built in and two tees (see Figure 27 ), the effect of the one-way valve is to prevent the flow of the cold water pipe from flowing into the hot water pipe when the user opens the hot water tap. The specific installation and use method is to use the "H-type cold and hot water ...
