摘要： A valve having high and low pressure seals. The valve has a housing in which is mounted a valve closing member having a sealing surface which faces an opening in the housing. A low pressure seal surrounds the opening and is biased into contact with the sealing surface. A high pressure seal also surrounds the opening. Pressure in the valve pushes the closing member against the low pressure seal, which moves toward the opening until the closing member contacts the high pressure seal.
摘要翻译：具有高低压密封的阀。阀具有壳体，其中安装有关闭构件，该阀关闭构件具有面向壳体中的开口的密封面。低压密封件围绕开口并被偏置成与密封表面接触。高压密封也围绕着开口。阀门中的压力将压缩机构压靠在低压密封件上，低密封件向开口移动，直到闭合件接触高压密封件。

摘要： A valve actuator is disclosed for use with short throw valves. The actuator includes a plate perpendicular to the valve stem that has a slot formed of regions having different radii of curvature centered on the valve stem. An eccentric cam is attached to a handle mounted on the valve stem. The cam extends through the slot and is rotatable for positioning at a radius corresponding to the radius of the different slot regions. When the cam is rotated so that it may traverse a slot region, the handle can be turned to move the valve closing member through an angle subtended by the slot region. This permits the valve to be opened or closed in a step-wise fashion and prevents rapid opening and closing of the valve that can cause a water hammer effect.
摘要翻译：公开了用于短路阀的阀致动器。致动器包括垂直于阀杆的板，其具有由具有以阀杆为中心的不同曲率半径的区域形成的槽。偏心凸轮连接到安装在阀杆上的手柄。凸轮延伸穿过狭槽并且可旋转以便以对应于不同槽区域的半径的半径进行定位。当凸轮旋转以使其可以穿过狭槽区域时，可以转动手柄以使阀关闭构件移动通过狭槽区域对着的角度。这允许阀以逐步的方式打开或关闭，并且防止阀的快速打开和关闭，从而导致水锤效应。

摘要： A flexible, resilient incompressible seal for a butterfly valve is disclosed formed from a loop having a perimeter mounting surface and a perimeter sealing surface with first and second oppositely disposed axial surfaces extend between the perimeter sealing and mounting surfaces. Channels are positioned in the axial surfaces in spaced relation around the seal. The channels extend from the perimeter mounting surface toward the perimeter sealing surface and provide fluid communication to the perimeter mounting surface allowing fluid trapped against the perimeter mounting surface to escape when compressed by closing of the valve. A void space is positioned in the perimeter mounting surface in the form of grooves or dimples allowing the perimeter sealing surface to deform under compression when the seal is captured within the valve and substantially restrained from deforming.
摘要翻译：公开了一种用于蝶形阀的柔性的弹性不可压缩密封件，其由具有周边安装表面和周边密封表面的环形成，第一和第二相对设置的轴向表面在周边密封表面和安装表面之间延伸。通道围绕密封件以间隔关系定位在轴向表面中。通道从周边安装表面朝向周边密封表面延伸并且提供与周边安装表面的流体连通，从而允许在周边安装表面上被封闭时被压缩的流体逸出。空隙空间以凹槽或凹坑的形式定位在周边安装表面中，从而当密封件被捕获在阀内并且基本上被限制变形时允许周边密封表面在压缩下变形。

摘要： A constant flow rate valve has a housing in which a rotatable sleeve is positioned between the valve's inlet and outlet. Apertures in the sleeve move into alignment with the valve's inlet and outlet upon sleeve rotation to establish the fluid flow rate. A piston is movable longitudinally within the sleeve bore. The piston has openings which align with the apertures in the sleeve upon longitudinal motion of the piston. Pressure ducts connect each end of the sleeve to the inlet and outlet. The piston moves in response to relative pressure changes in the inlet and outlet communicated by the pressure ducts. The area of overlap between the piston's openings and the sleeve's apertures varies with piston motion to ensure a constant flow rate in spite of relative inlet and outlet pressure changes. The ends of the sleeve are in fluid communication to control the response sensitivity of the piston.
摘要翻译：恒定流量阀具有壳体，其中可旋转的套筒位于阀的入口和出口之间。在套筒旋转时，套筒中的孔与阀的入口和出口对齐以建立流体流速。活塞可在套筒孔内纵向移动。活塞在活塞的纵向运动时具有与套筒中的孔对准的开口。压力管道将套管的每一端连接到入口和出口。响应于由压力管道连通的入口和出口的相对压力变化，活塞移动。活塞开口和套筒孔之间的重叠区域随着活塞运动而变化，以确保相对入口和出口压力变化的恒定流量。套筒的端部流体连通以控制活塞的响应灵敏度。
