SOLENOID VALVE
First Claim
1. A solenoid valve, comprising:
- a valve body having an inlet port, an outlet port, and a valve seat formed between the two ports;
a sealing assembly provided on the valve seat; and
a plunger configured to be driven toward or away from a top portion of the sealing assembly by a solenoid in order to make the sealing assembly close or open the valve seat;
the solenoid valve being characterized in that;
a casing is coupled to the valve body, the casing has an outer bottom portion protrudingly provided with a guide post, and the guide post is formed therein with a flow channel;
the sealing assembly comprises a rigid disk and a flexible diaphragm, the flexible diaphragm is coupled to the rigid disk and has a bottom side facing an orifice of the valve seat of the valve body, the guide post of the casing has a portion fitted in a central opening of the sealing assembly, and the sealing assembly is vertically movable along an axis defined by the guide post; and
the plunger has a bottom portion facing an inlet of the flow channel of the guide post of the casing.

Abstract
A solenoid valve includes: a valve body with a valve seat therein; a sealing assembly provided on the valve seat; and a plunger to be driven by a solenoid to make the sealing assembly open or close the valve seat. The solenoid valve is characterized in that: a casing is coupled to the valve body and has an outer bottom portion protrudingly provided with a guide post; a flow channel is formed in the guide post; the sealing assembly includes a rigid disk, a flexible diaphragm, whose bottom side faces an orifice of the valve seat, and a central opening, in which the guide post is partially fitted; and the plunger has a bottom portion facing the inlet of the flow channel. With the guide post being stationary and linking the plunger and the sealing assembly, the solenoid valve features reduced power consumption and a low chance of solenoid failure.
