摘要： An indicator that the cartridge is draining slowly is placed on top of the cartridge. When slow draining causes urine to pool on top of the cartridge, liquid enters a float housing, causing an indicator to change color. The indicator is visible through a lens in a diverter. The indicator may be a disk that undergoes a chemical reaction to change color or a float that flips over to reveal a side having a different color. When the cartridge is operating properly, the float displays a first color. Flipping of the float reveals a second color to the observer. A color change indicates that the cartridge needs to be replaced.

摘要： A dry trap valve, such as usable in a non-flushing urinal and other drains, is employed to transport a fluid, such as urine or other wastewater to a sewer line for receipt and disposal of the wastewater. The dry trap valve includes a holder (e.g., a band holder) having an entry for receipt of the wastewater, a drain for disposal of the wastewater, a passageway (e.g., dent, depression or bypass) for conducting the wastewater from the entry to the drain, and an element e.g., a sealing band) for sealingly covering the passageway. The sealing band includes a hinged portion adjacent the lower end of the dent and is disposed to articulate upon flow of the wastewater from the dent and to permit the wastewater to flow to the drain and to close in the absence of the wastewater flow. Gases from the sewer line also press upon the sealing band in the absence of wastewater flow to further seal the dent. Thus, the memory of the elastomeric material is not essential but, rather, the forces of gravity and the force of the sewer gas keeps the passage closed to the sewer gases that would otherwise back up through the valve.

摘要翻译： 使用诸如可用于非冲洗小便器和其它排水管的干式疏水阀将诸如尿液或其它废水的流体运送到下水道以接收和处理废水。 干式疏水阀包括具有用于接收废水的入口的保持器（例如，带保持器），用于处理废水的排水口，用于将废水从入口处输入的通道（例如，凹陷，凹陷或旁路） 排水口，以及诸如密封带的元件），用于密封地覆盖通道。 密封带包括邻近凹陷的下端的铰接部分，并且设置成在来自凹坑的废水流动时进行关节运动，并且允许废水流到排水管并在不存在废水流的情况下关闭。 在没有污水流动的情况下，来自下水道的气体也压在密封带上，以进一步密封凹坑。 因此，弹性体材料的记忆不是必需的，而是重力和下水道气体的力保持通道关闭到否则将通过阀回流的下水道气体。
