The invention relates to an auxiliary water tank pressure cover and an auxiliary water tank, the auxiliary water tank pressure cover comprises a cover body and a valve core arranged in the cover body, the valve core comprises an upper valve core and a lower valve core, and the lower valve element is coaxially connected to the bottom end of the upper valve element, and the lower valve element is always static relative to the upper valve element in the circumferential direction. When the auxiliary water tank pressure cover covers a kettle opening of an auxiliary water tank, the upper valve element and the lower valve element are kept relatively static in the circumferential direction all the time, that is, the upper valve element and the lower valve element do not rotate relatively, and therefore the elastic piece arranged in the lower valve element does not twist in the axial direction; the pressure between the elastic piece and the lower valve element is effectively guaranteed to be in an accurate state when the elastic piece seals the lower valve element, and the problem that the auxiliary water tank relieves pressure in advance is remarkably solved.

    本申请涉及一种副水箱压力盖及副水箱,其包括盖体和设于所述盖体内的阀芯,所述阀芯包括:上阀芯,其顶端与所述盖体连接;下阀芯,其同轴连接于所述上阀芯底端,且所述下阀芯在周向上始终与所述上阀芯相对静止。实现副水箱压力盖在盖合至副水箱的壶口上时,其上阀芯与下阀芯之间将始终在周向上保持相对静止,即两者之间不会产生相对转动,因此设置于下阀芯内的弹性件也将不会在轴向上产生扭转,有效保障弹性件在密封下阀芯时两者之间的压力处于准确状态,显著减少了副水箱提前泄压的问题。
