Abstract:
The present application relates to a constant pressure switch apparatus and a water heating system. The constant pressure switch apparatus includes: a body inside which a flow passage is provided, the flow passage having an inlet and an outlet; a first blocking member and an attraction member that can be magnetically attracted to each other; the first blocking member having a blocking position and a communicating position that are spaced apart at a preset distance; the first blocking member being able to move towards the communicating position when a pressure difference between both sides of the first blocking member in a direction from the inlet to the outlet is greater than an attraction force between the first blocking member and the attraction member; and the first blocking member being able to move towards the blocking position when a pressure difference between both sides of the first blocking member in a direction from the inlet to the outlet is less than an attraction force between the first blocking member and the attraction member. The constant pressure switch apparatus and water heating system provided in this application can enable the circulating pump to maintain a connected state of the flow passage without increasing pressure, and can also avoid the problem of series flow of cold and hot water.

Claim (Index 13):
The constant pressure switch apparatus according to  claim 1 , wherein: the flow passage runs through the first body; the constant pressure switch apparatus further comprises an outer pipe which is provided outside the first body, the first blocking member is a sleeve that has one end closed and is provided a through-hole on its side wall, the first blocking member is provided at the end of the outlet of the first body and its side wall is located between the first body and the outer pipe; when the pressure difference is greater than the attraction force between the first blocking member and the attraction member, the outlet can be in communication with the through-hole; and when the pressure difference is less than the attraction force between the first blocking member and the attraction member, the first blocking member can block the outlet.
