Description

TECHNICAL FIELD

[0001] The utility model relates to a waterway switch valve. BACKGROUND

[0002] The electromagnetic valve is a kind of waterway switch valve for magnetically controlling the opening and closing of valve.

[0003] In the related art, the US patent with the application number US12932110 discloses an automatic fluid flow control system for a fluid system having a fluid inlet, a fluid outlet and a fluid chamber communicating between the fluid inlet and the fluid outlet, wherein the automatic fluid flow control system comprises: a safety valve adapted to be sealingly disposed in the fluid chamber in a non-movable manner, having a diaphragmless configuration for sealing fluid flow from the fluid inlet to the fluid outlet, wherein the safety valve has a fluid passage for controlling the flow rate of the fluid flowing from the fluid chamber to the fluid outlet, and comprises a valve stopper sealingly closing the fluid passage for controlling the fluid flowing from the fluid chamber to the fluid outlet; wherein the valve stopper is driven to move between a closed position and an open position, wherein in the closed position, the valve stopper is sealingly kept to close the fluid passage to prevent the fluid from flowing to the fluid outlet, and in the open position, the valve stopper is moved to unseal the fluid passage to allow the fluid to flow to the fluid outlet through the fluid passage; further comprising an actuator driven to move the safety valve between the closed position and the open position, wherein the actuator non-coaxially extends to the fluid passage towards the valve stopper, and the actuator is arranged such that when the actuator is driven to move, the actuator is driven to slide the valve stopper to open the fluid passage; further comprising a generator operably coupled with the actuator and arranged in such a way that when the generator is activated, the generator drives the actuator to move so as to move the valve stopper to open the fluid passage.

[0004] It can be understood that, since the generator is located at the water inlet of the fluid system, when the valve is opened, the external water source directly enters into the flow passage, which causes the generator to be in contact with water for a long time, resulting in a high failure rate and a short service life, which is not conducive to long-term use by users, and the subsequent maintenance cost is also increased.
