    • A vacuum relief valve includes: a housing with a central cavity, the housing having a system branch, a vacuum branch, a pilot branch, and an exhaust branch, each of the branches in fluid communication with the central cavity and having a respective port; a piston assembly comprising a first disk located in the pilot branch, a second disk located adjacent the exhaust branch, and a connecting member to which the first and second disks are mounted; and an actuator attached to a pilot seal, the actuator configured to move the pilot seal between a closed position, in which the pilot seal is positioned in and seals the pilot port, and an open position, in which the pilot seal is spaced from and does not seal the pilot port. When the pilot seal is in the closed position, the second disk is positioned on and seals the exhaust port, and when the pilot seal is in the open position, the second disk is spaced from and does not seal the exhaust port. In this configuration, often a smaller, less expensive actuator may be used to actuate the valve.
    • 真空释放阀包括:具有中心腔的壳体,壳体具有系统分支,真空分支,先导分支和排气分支,每个分支与中心腔流体连通并具有相应的端口; 活塞组件,包括位于所述导向分支中的第一盘,邻近所述排气分支的第二盘,以及安装所述第一和第二盘的连接构件; 以及附接到先导密封件的致动器,所述致动器被配置为将所述先导密封件在所述先导密封件定位在其中并且密封所述先导端口的关闭位置和打开位置之间移动,在所述打开位置中, 不密封先导端口。 当导向密封件处于关闭位置时,第二盘被定位在并且密封排气口,并且当导向密封件处于打开位置时,第二盘与排气口间隔开并且不密封排气口。 在该配置中,通常可以使用较小的较便宜的致动器来致动阀。

    • A refiner steam separation system according to the present invention includes a blowline for transporting a mixture of fiber material from a refiner to an inlet of a steam separator. Waste steam is discharged from the separator through a waste steam outlet. Cleaned fiber material is discharged from the separator through an exit, which prevents a substantial portion of the waste steam from passing through the exit. A relay pipe communicates with the exit and a dryer duct, and transports cleaned fiber material therebetween. A resin input communicates with the relay pipe, and supplies resin therein. The resin is mixed with the cleaned fiber material prior to the cleaned fiber material being dried in the dryer duct. The present invention is also directed to a method of reducing VOC emissions generated during refining cellulosic fibrous material.
    • 根据本发明的精炼机蒸汽分离系统包括用于将纤维材料从精制机的混合物输送到蒸汽分离器的入口的吹制线。 废蒸汽通过废蒸汽出口从分离器排出。 清洁的纤维材料通过出口从分离器排出,这防止大部分废蒸汽通过出口。 继电器管与出口和干燥器管道连通,并在其间输送清洁的纤维材料。 树脂输入与中继管连通,并在其中供应树脂。 在清洁的纤维材料在干燥器管道中干燥之前,树脂与清洁的纤维材料混合。 本发明还涉及减少精制纤维素纤维材料期间产生的VOC排放的方法。
