Title: SOLENOID VALVE
Abstract:
Disclosed is a solenoid valve (10). The solenoid valve (10) comprises a first valve body section (30), a second valve body section (40), and an inflatable section (50). Multiple airflow channels in communication with each other are disposed in the first valve body section, the second valve body section and the inflatable section. The first valve body section is provided with an air discharge portion (32) in communication with the airflow channel and a first movable spool (33) located in the airflow channel. The second valve body section is provided with an air intake portion (42) in communication with the airflow channel and a second movable spool (43) located in the airflow channel. The inflatable section is used for connecting an object (20) to be inflated. By changing the position of the first movable spool and the position of the second movable spool, the states for inflating or deflating the object (20) to be inflated or maintaining the air pressure of the object (20) to be inflated can be formed.
