Title:
SOLENOID VALVE
Document Type and Number:
WIPO Patent Application WO/2019/205989
Kind Code:
A1
Abstract:
A solenoid valve, comprising a first pipeline, an electromagnetic mechanism for controlling the opening and closing of the first pipeline, and a pressure relief mechanism communicating with the first pipeline. The pressure relief mechanism comprises a first mount (3) having a first cavity (2), a second pipeline (4) communicating with the first cavity (2) and the first pipeline, a water outlet (5) communicating with the first cavity (2), and an overflow port (6) communicating with the first cavity (2) and located above the water outlet (5). A communication port (7), by which the second pipeline (4) communicates with the first cavity (2), is located below the water outlet (5). The pressure relief mechanism further comprises a first movable mechanism vertically movable and disposed in the first cavity (2) and a second movable mechanism vertically movable and disposed in the first movable mechanism, wherein the first movable mechanism is used to block the communication port (7) or to cause the communication port (7) to communicate with the water outlet (5), and the second movable mechanism is used to block the communication port (7) or to cause the communication port (7) to communicate with the overflow port (6). If the water outlet is blocked, the pressure relief mechanism provided in the solenoid valve discharges water in the first cavity via the overflow port, thereby effectively protecting the entire system.
