Isolation diaphragm type solenoid valve

The utility model discloses an isolation diaphragm type solenoid valve, including valve body, the electromagnetic drive portion on the valve body of installing, install solenoid in electromagnetic drive portion, and set up the isolation diaphragm between valve body and electromagnetic drive portion, be provided with the flow path in the valve body, just the flow path forms inlet and liquid outletin the valve body, isolation diaphragm is by main diaphragm with around constituteing at main diaphragm vice diaphragm peripheral, that link to each other with it, vice diaphragm is located directly over inlet, the liquid outlet, vice diaphragm lower surface is the ripple struction. Through being the ripple struction with isolation diaphragm with the setting of flow path contact surface, increasethe area of contact of isolation diaphragm and flow path to the membrane that improves isolation diaphragm is wide, guarantees that isolation diaphragm still has sufficient frictional force under thecondition of the external d
