Problems solved by technology

[0004] However, there is a problem with this circulating water heater. When the farthest faucet is turned on to open the cold water outlet, part of the water may pass through the water heater and then flow out from the cold water faucet through the one-way valve. When the flow of cold water flowing through the water heater is large The water heater will start, causing confusion for the user

Abstract

The invention relates to a one-way valve. The one-way valve comprises a valve shell and a valve element assembly. The valve element assembly is arranged in the valve shell and can enable water to flowto a cold water end from a hot water end in a one-way manner. The one-way valve is characterized in that an impeller is arranged in a cold water outlet in an up-down moving manner, a support is arranged at the position, located at the cold water end, in the valve shell in a back-and-forth manner, one end of the support is close to the impeller, and the other end of the support can be matched witha one-way valve element of the valve element assembly so as to limit opening of the one-way valve element; and a compression spring for forcing the support to move towards the impeller all the time is arranged on the inner wall of the valve shell. After cold water is used, the one-way valve element is blocked by the support and is in the closed state all the time, and therefore, it can be guaranteed that a water heater cannot be started when only the cold water is used, and the user trouble is reduced.

Description

technical field [0001] The invention relates to a water valve applied to a pipeline of a gas water heater, and also relates to a gas water heater. Background technique [0002] When common gas water heaters are in use, the cold water in the original pipeline needs to be discharged before hot water can be produced. At present, water heater manufacturers have introduced circulating water heaters to solve this problem. The principle is to build a circulating pump in the water heater. The water in the pipes of the home is preheated in advance, so that the cold water will flow out after heating, avoiding waste. [0003] Circulating water heater structure such as figure 1 As shown, the water heater is connected with a cold water pipe 4a and a hot water pipe 3a, the cold water pipe 3a forms a one-way circulating waterway with the hot water pipe 3a through a one-way valve 6a, the cold water 3a pipe is connected with a water inlet pipe 2a, and multiple faucets 5a are arranged in par...
