Integrated one-inlet-and-two-outlet waterway switching module and waterway module

Abstract

The invention discloses an integrated one-inlet-and-two-outlet waterway switching module and a waterway module. The integrated one-inlet-and-two-outlet waterway switching module comprises an overload protection motor, a motor mounting snap spring and a three-way valve assembly, wherein the overload protection motor is fixedly arranged on the three-way valve assembly through the motor mounting snap spring; a three-way push rod is placed in a three-way valve body hole, and sequentially penetrates through a return spring, a retaining ring and a dynamic sealing ring and is fixedly arranged on a three-way valve body by an opening retaining ring I; a valve port sealing block is fixedly arranged at the tail end of the three-way push rod by an opening retaining ring II; an outer ring of the valve port sealing block seals a three-way valve port II, and static sealing rings are arranged in o-shaped ring grooves in the external wall of the three-way valve body. The waterway module comprises a water outlet module and the waterway switching module. According to the integrated one-inlet-and-two-outlet waterway switching module and the waterway module, the most-compact integrated one-inlet-and-two-outlet three-way structure is provided, so the structure of the water outlet module can be simplified, and machining or mold opening is easier, and the technical problem that leakage is caused due to the fact that flexible deformation is easy due to the adoption of a split sealing structure or long-push-rod double sealing seats can be solved.

Description

technical field [0001] The invention relates to a waterway module used in a wall-hung boiler system, in particular to an integrated one-inlet and two-outlet waterway switching module. The present invention also relates to a waterway module using the above-mentioned waterway switching module. It is a new type of valve technology with major innovation in structure. Background technique [0002] The waterway module is a key and indispensable component for waterway system control in gas wall-hung boilers (also known as domestic boilers). Its function is to integrate the circulation pipeline into one body, and integrate functions such as waterway switching, water replenishment, and sanitary water flow detection. The waterway module is generally attached with various interfaces such as a circulating water pump, a safety valve, a temperature sensor, a pressure sensor, and an expansion tank. The principle of the waterway module is: through the connection with the bathroom heat ex...
