摘要： A vacuum relief valve assembly includes a vacuum valve member located below a top cover plate and is thus protected from the atmosphere. First passageways defined in part by a bottom cover plate provide communication between the outside atmosphere and the lower surface of the valve. Second passageways provide communication between the upper surface of the valve and the inside of the container. When the pressure in the container is below atmospheric, atmospheric pressure acting on the bottom of the valve lifts the valve and air flows through the first and second passageways until atmospheric pressure is reached in the tank. A pressure relief valve is mounted for pivotal movement relative to an opening providing communication between the pressure in the tank and the first passageways to vent pressure in the tank. The pressure relief valve is protected from the atmosphere by the top cover plate, and in one embodiment, by the vacuum relief valve.
摘要翻译：真空安全阀组件包括位于顶盖板下方的真空阀构件，因此被保护免受大气压力的影响。由底盖板部分限定的第一通道提供了外部气氛和阀门下表面之间的连通。第二通道提供阀的上表面和容器内部之间的连通。当容器中的压力低于大气压时，作用在阀底部的大气压升高阀门，空气流过第一和第二通道，直到达到大气压力。安装压力释放阀以相对于开口提供枢转运动，该开口提供罐中的压力和第一通道之间的连通以排出罐中的压力。减压阀通过顶盖板被保护，并且在一个实施例中由真空释放阀保护。

摘要： A control arrangement is provided to control discharges of compressed gas into vessels containing difficult to unload material comprising one or more control valves connected in operative relation to discharge valves operative to discharge compressed gas from an accumulator into the vessel. The control valves are provided with a timer for controlling the time of discharge of compressed gas from the accumulator. This timer may comprise a pneumatic, electro-mechanism and/or electronic timer. The control arrangement may also include means for applying pressure gas to discharge valves which are in operative relation with accumulator discharge devices which are not being utilized for unloading. Various arrangements for mounting the accumulators, discharge valves, conduits, and discharge devices are illustrated in connection with a railway hopper car. Certain discharge device mounting arrangements are preferred in unloading certain types of lading.

摘要： Apparatus is disclosed for assisting in the unloading of a difficult to unload lading from a vessel. An accumulator is mounted adjacent the vessel. A first conduit connects the accumulator with a valve for periodic discharge of the accumulator. A self-indexing elbow is rotatably mounted on the vessel and extends within the vessel. A second conduit connects the valve with the elbow. The elbow includes an elbow conduit portion in fluid communication with the second conduit. The elbow conduit portion has a center line defining an axis about which the elbow is rotatable. The elbow also includes an elbow portion having an elbow center line passing therethrough. The elbow portion has a discharge end having a discharge opening through which the elbow center line passes. At the discharge end the elbow center line is offset with respect to the axis so as to define a moment arm between the elbow portion and the axis. The accumulator is pressurized with gas sufficient to dislodge bridged or clogged lading in the vessel and sufficient to cause said elbow to rotate relative to the axis. A bearing assembly is mounted between the elbow conduit portion and the vessel, having a frictional force sufficient to limit rotation of said elbow with respect to the vessel, such that rotation ceases at a new angular position relative to the axis prior to the next discharge of pressurized gas from the accumulator. The elbow may be attached so that the frictional force can be adjusted to vary the extent of elbow rotation after each blast of gas is discharged from the elbow. A check valve may be applied to the discharge end of the elbow to prevent lading from entering the elbow. Lading clearing openings in addition to the discharge opening may be provided in the elbow portion to facilitate removal of lading or other material which may tend to hold the elbow in place and prevent the same from rotating as a blast of gas is discharged from the discharge opening.
摘要翻译：公开了用于帮助从船舶卸载难以卸载的装置。蓄能器安装在容器附近。第一导管将蓄能器与阀门连接，用于蓄能器的周期性排放。自动分度弯头可旋转地安装在容器上并在容器内延伸。第二个管道将阀门与肘管连接起来。弯头包括与第二导管流体连通的弯管导管部分。弯头导管部分具有限定肘管可旋转的轴线的中心线。肘部还包括具有穿过其中的弯头中心线的肘部。肘部具有排出端，排出口具有肘中心线通过的排出口。在排出端，弯头中心线相对于轴线偏移，以便在弯头部分和轴线之间限定力矩臂。用足够的气体对蓄能器进行加压，以便排出容器中的桥接或堵塞的填料，并足以使所述弯头相对于轴旋转。轴承组件安装在弯头导管部分和容器之间，具有足以限制所述弯头相对于容器的旋转的摩擦力，使得在下一次排出之前，旋转在相对于轴线的新的角度位置处停止来自蓄能器的加压气体。可以安装弯头，使得可以调节摩擦力以改变每次气流从肘部排出的肘关节旋转的程度。止回阀可以应用到肘部的排放端，以防止提升进入肘部。可以在肘部中设置除了排出口之外的提升清除开口以便于移除可能容易将肘部保持在适当位置的提升或其他材料，并且防止其因气体喷出而从排出口排出。

摘要： In a bottom operable tank car lading valve assembly, a combination skid and lading valve seat for the lading valve closure is provided, which is attached to the tank car universal flange with mechanical fasteners. The valve seat portion extends inwardly and upwardly from the universal flange and includes a machined seat. The skid portion extends upwardly and outwardly from the universal flange, forming a circumferential taper, and the upper portion abuts the bottom of the tank. The skid portion protects the lading valve closure and the lading valve seat against impacts which might normally cause unseating of the valve closure and escape of the lading in the absence of the skid portion.

摘要： Enclosed covered hopper cars are interconnected by conduits to form a partial or complete unit-train for liquid lading service, particularly liquid petroleum. The conduits are at least partially flexible to negotiate curves in the road bed. Preferably the conduits joining adjacent hoppers extend between openings located in the upper portion of the end hoppers. Preferably at the bottom of each hopper a hopper floor is removably attached to a hopper outlet mounting flange. The hopper floor includes a lading opening. A longitudinal tube is located below the lading openings, extending between the end floor sheets. A conduit extends from the upper portion of one end hopper in the car to the longitudinal tube to enable the cars to be unloaded by positive pressure applied to an end car of a group of cars. The car may be converted to particulate solid lading service by removing the conduits extending between adjacent cars, closing the openings at the ends of the car, removing the hopper floor from the hopper mounting flange, and attaching to the hopper mounting flange an appropriate outlet for the particular particulate solid lading to be transported.
