    • A gas control unit for a boiler is provided which can satisfactorily control the supply and shut-off of gas. The gas control unit for a boiler includes: 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; and 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. Here, 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. Accordingly, since the opening and shutting means is coupled to the rod through the use of the coupling member and the coupling groove, the opening and shutting means can move within a predetermined range about the coupling member with an application of an external force. Therefore, even when the opening and shutting means and the gas outlet depart in center from each other, it is possible to shut the gas outlet, thereby satisfactorily controlling the supply and shut-off of gas.
    • 提供了一种用于锅炉的气体控制单元,其可以令人满意地控制气体的供应和切断。 锅炉用气体控制单元包括:中空壳体; 设置在所述壳体中的螺线管; 插入到螺线管中并具有从壳体突出的下部的杆; 打开和关闭装置,其设置在杆的下端以便打开和关闭气体出口; 以及弹簧,其设置在所述壳体与所述打开和关闭装置之间,以便向下弹性地推动所述打开和关闭装置。 这里,连杆构件形成在杆的下端,并且在开闭装置中形成有联接构件插入其中的联接槽,以允许打开和关闭装置移动。 因此,由于打开和关闭装置通过使用联接构件和联接槽联接到杆,打开和关闭装置可以通过施加外力而在联接构件周围的预定范围内移动。 因此,即使打开和关闭装置和气体出口彼此中心离开,也可以关闭气体出口,从而令人满意地控制气体的供给和切断。
