Abstract:
1. A gas control unit for a boiler comprising: a hollow housing; a solenoid that is disposed in the housing; a rod that is inserted into the solenoid and that has a lower part protruding from the housing; opening and shutting means that is disposed at the lower end of the rod so as to open and shut a gas outlet; a spring that is disposed between the housing and the opening and shutting means so as to elastically urge the opening and shutting means downward, wherein a coupling member is formed at the lower end of the rod and a coupling groove into which the coupling member is inserted is formed in the opening and shutting means so as to allow the opening and shutting means to move; wherein a first attachment protrusion is formed on the bottom surface of the housing, a second attachment protrusion is formed on the top surface of the opening and shutting means, and the upper end and the lower end of the spring are inserted onto the first attachment protrusion and the second attachment protrusion, respectively; wherein the opening and shutting means includes an elastic pad that has the coupling groove formed therein and a cover that is disposed on the top of the elastic pad and that has the second attachment protrusion formed therein; wherein the housing includes a C-shaped first plate of which the bottom surface is opened and a panel-shaped second plate that is coupled to the opened bottom surface of the first plate; and wherein a magnetic induction protrusion that is inserted into the solenoid is formed at the center of the first plate and a magnetic induction groove corresponding to the magnetic induction protrusion is formed in the rod.
