摘要： An improved sealing means for use with a slide gate which is slidably mounted for opening and closing movement relative to a seat forming frame defining a fluid flow orifice. The sealing means comprises a resilient sealing member adapted to be received in a groove in the frame, the groove having an outer compartment in which the body of the sealing member is sealed and an inner compartment underlying the outer compartment, the sealing member having an outwardly projecting contoured face adapted to be contacted and displaced laterally inwardly by the gate as it is closed, the lateral displacement of the face of the sealing member causing a rear portion of its body to be displaced into the inner compartment of the groove, thereby accommodating the sealing member to the slide and relieving forces acting to shear the sealing member.
摘要翻译：一种用于滑动门的改进的密封装置，其可滑动地安装成用于相对于限定流体流动孔的座形成框架的打开和关闭运动。密封装置包括适于容纳在框架中的凹槽中的弹性密封构件，凹槽具有密封构件的主体被密封的外部隔室和位于外部隔室下方的内部隔室，密封构件具有外部突出的轮廓面适于在门被关闭时被横向向内接触和移位，密封构件的表面的横向位移导致其主体的后部移动到槽的内部隔室中，从而容纳密封构件到滑块和用于剪切密封构件的释放力。

摘要： A butterfly gate valve for control of water in treatment, waste water plants and the like, wherein the gate is mounted on a one-piece shaft. The lower end of the shaft rotates in a radial bearing, and a radial bearing and a thrust bearing are provided on the upper end of the shaft above the gate. The upper bearings are housed in a protective bonnet and may be sealed from access of water. The upper bearings are easily accessible through a removable bonnet cover. The vertical position of the leaf within the frame is adjustable by means of a rotatable threaded member reacting against a mating member above the frame.
摘要翻译：一种用于控制处理中的水的蝶形闸阀，废水处理设备等，其中门安装在单件轴上。轴的下端以径向轴承转动，在闸门上方的轴的上端设有径向轴承和推力轴承。上轴承安装在保护罩内，并可能被水密封。上轴承可以通过可拆卸的盖帽轻松抵达。框架内的叶片的垂直位置可通过与框架上方的配合构件反作用的可旋转螺纹构件来调节。
