Problems solved by technology

[0004] However, the currently used one-way valve usually uses a spring as a reset mechanism. When the water heater controls the circulating pump to open the one-way valve with a certain initial pressure, the spring will generally be compressed, and the restoring force acting on the blocking mechanism will increase. Large, in order to prevent the pressure relief problem caused by the opening of the one-way valve, the circulation pump needs to continuously increase the pressure to maintain the open state of the one-way valve to ensure a

Abstract

The invention discloses a constant-pressure switching device and a hot water system. The constant-pressure switching device comprises a main body, a blocking piece and an attraction piece, wherein a flow channel is formed in the main body; the flow channel is provided with an inlet and an outlet; the blocking piece and the attraction piece can be in magnetic attraction; the blocking piece is provided with a blocking position and a communication position which are arranged at a preset distance; when the differential pressure of the two sides of the blocking piece in the direction from the inlet to the outlet is larger than the attraction force between the blocking piece and the attraction piece, the blocking piece can move towards the communication position; when the differential pressure of the two sides of the blocking piece in the direction from the inlet to the outlet is smaller than the attraction force between the blocking piece and the attraction piece, the blocking piece can move towards the blocking position. The constant-pressure switching device and the hot water system disclosed by the invention enable the flow channel to be kept in a communication state without pressure increase of the circulating pump and meanwhile, prevent the problem of cold and hot water streaming.

Description

technical field [0001] The present application relates to the technical field of water heaters, in particular to a constant pressure switch device and a hot water system. Background technique [0002] The water heater has become one of the necessary household equipment, which can provide both hot water for bathing and hot water for the kitchen, but no matter how the water heater is installed, there will always be a section of water pipe between the water heater and each water point, and the water point has not been used for a long time. When using water, the hot water in this section of the water pipe will gradually become colder. When using water at the next water point, especially when taking a bath next time, this section of cold water will be released first. This not only causes a lot of waste of water resources, but also brings Give the user an uncomfortable bathing experience. According to research estimates, in a ten-story residential building, the average length of ...
