Abstract

The invention discloses a valve and a hot water system thereof. The valve is provided with a first opening part, a second opening part and a one-way valve arranged between the first opening part and the second opening part. When the one-way valve is opened, first liquid input from the first opening part is allowed to flow to the second opening part. The valve is provided with a third opening part.The third opening part is used for outputting second liquid input from the second opening part. The valve is further provided with a valve element assembly located on the downstream part of the one-way valve. The valve element assembly communicates with the one-way valve and the second opening part when the one-way valve is opened. By means of the valve element assembly, when the second liquid isinput through the second opening part, the open area between the one-way valve and the second opening part is reduced. By means of the valve, the situation that hot water is output when a user uses cold water can be effectively avoided, and the water using experience is improved.

Description

technical field [0001] The application relates to the field of valves, in particular to a valve and a hot water system thereof. Background technique [0002] When using existing water heaters, users have to put cold water in for a period of time before using hot water. Especially in winter when the temperature is low, not only does the tap water flow away in vain, but also delays a lot of time, which greatly affects the user experience. This is a common problem in the water heater industry. [0003] In order to solve this problem, in the prior art, a preheating circulation return valve is mainly installed between the hot water outlet pipe and the cold water pipe of the water heater, and the cold water pipe is used as the return pipe to establish a preheating circulation pipe between the water point and the water heater. In the non-water state, the low-temperature water is sent to the water heater through the preheating circulation pipeline for heating until the water temper...
