Abstract: A fire protection sprinkler includes a body having an input end and an output end, the body having an output orifice at the output end. The sprinkler includes a frame extending from the body in the output direction and a deflector supported by the frame positioned opposite the output orifice. Also, the sprinkler includes a seal assembly which seals the output orifice. The seal assembly has a first side and a second side, the first side bearing identifying indicia associated with the orientation of the seal assembly. When the first side is oriented in the input direction, a portion of the indicia is visible from the input end, to indicate a correct assembly. However, when the first side is oriented in the output direction, none of the indicia is visible from the input end, indicating incorrect assembly. The identifying indicia can take the form of one or more of the following: a color, a character, a symbol, and a mark. The seal assembly can include a cap and an annular spring washer, such as a Belleville spring washer, used to provide a pressure seal.

Abstract translation: 防火喷头包括具有输入端和输出端的主体，主体在输出端具有输出孔。 喷洒器包括从主体沿输出方向延伸的框架和由与输出孔相对定位的框架支撑的偏转器。 此外，喷洒器包括密封输出孔的密封组件。 密封组件具有第一侧面和第二侧面，第一侧面轴承识别与密封组件的取向相关联的标记。 当第一面在输入方向上定向时，标记的一部分从输入端可见，以指示正确的组件。 但是，当第一面朝向输出方向时，从输入端看不到任何标记，表示不正确的装配。 识别标记可以采取以下一种或多种形式：颜色，字符，符号和标记。 密封组件可以包括盖和用于提供压力密封的环形弹簧垫圈，例如贝氏弹簧垫圈。
