    • A water valve assembly includes a valve body having defined therein (1) a first channel, and (2) a first threaded portion. The water valve assembly also includes a first stop attached to the valve body and a second stop attached to the valve body, the second stop being positioned relative to the first stop such that a recess is defined therebetween. The water valve assembly further includes an attachment mechanism having a base and an arm attached to the base. The attachment mechanism has defined therein (1) a second channel, and (2) a second threaded portion. The arm includes a tab, and the arm is positionable in a first lowered position relative to the base when the tab is located outside of the recess. In addition, the arm is positionable in a second lowered position relative to the base when the tab is located within the recess. Furthermore, the tab contacts the first stop so as to move the arm relative to the base when the arm is moved from the first lowered position to the second lowered position.
    • 水阀组件包括其中限定有(1)第一通道的阀体和(2)第一螺纹部分。 水阀组件还包括附接到阀体的第一止动件和附接到阀体的第二止动件,第二止动件相对于第一止动件定位,使得在其间限定凹部。 水阀组件还包括附接机构,其具有底座和连接到基座的臂。 附接机构在其中限定了(1)第二通道,和(2)第二螺纹部分。 臂包括突片,并且当突片位于凹部外部时,臂可相对于基座定位在第一下降位置。 此外,当突片位于凹部内时,臂可相对于基座定位在第二下降位置。 此外,当臂从第一降低位置移动到第二降低位置时,突片接触第一挡块以便相对于基座移动臂。
