摘要： A check valve assembly includes a generally bell shaped casing having a flared, open end section and a fluid inlet in opposed relation to the flared end section. A body removably connected to the casing covers a portion of the flared end section and has a fluid outlet as well as two spaced, outwardly extending ball guiding members which are matingly received within opposed walls of the casing. The ball guiding members are configured to shift the ball along a path of travel between a first, flow impeding position adjacent the fluid inlet and a second position spaced from the inlet and disposed laterally of a substantially straight fluid passageway extending between the inlet and the outlet. In preferred forms of the invention, the path of travel of the ball has a variable slope which approaches zero as the ball reaches its uppermost, flow enabling position so that a minimum amount of fluid pressure on the ball can retain the latter in its uppermost position, ball flutter and fluid turbulence is substantially reduced. In other forms of the invention, the body includes a stop which contacts the ball in a relatively small surface area of the latter when the ball is in its flow enabling position so that a portion of the fluid flowing through the valve assembly travels around the ball and cleanses the same, and so that stagnant pockets of fluid are eliminated.
摘要翻译：止回阀组件包括通常钟形的壳体，其具有扩张的开口端部分和与扩口端部相对的流体入口。可移除地连接到壳体的主体覆盖扩口端部的一部分并且具有流体出口以及两个间隔开的向外延伸的球引导构件，其被配合地容纳在壳体的相对壁内。球引导构件被构造成沿着相对于流体入口的第一阻流位置和与入口间隔开的第二位置之间的行进路径移动球，并且设置在入口和出口之间延伸的基本上直的流体通道的横向。在本发明的优选形式中，当球到达其最上面的流动使能位置时，球的行进路径具有接近零的可变斜率，使得球上的最小量的流体压力能将球保持在其最高位置球颤和液体湍流显着降低。在本发明的其他形式中，当球体处于其使能位置时，主体包括一个与球体相对较小的表面区域接触的止挡件，使得流过阀门组件的流体的一部分绕球运动并清洗相同，从而消除了积液的凹陷。

摘要： A tank mounted discharge conduit assembly for use with a submersible pump unit comprises a base member connected to the tank as well as an upright body having a fluid conduit therein. The base member has an upwardly extending portion which is complementally received within a lower portion of the upright body, in order to provide support against lateral deflection of the body as well as to prohibit the flow of fluids through a lower end of the conduit. The body also integrally includes a pair of upright, spaced, elongated, U-shaped guides which are configured to slidably receive an outlet flange of the pump and shift the latter toward a position of fluid communication between the pump and an opening in the body communicating with the fluid conduit therein. The guides advantageously include yieldable wall portions which accommodate lateral movements of the pump unit to facilitate raising and lowering of the pump by a rope-equipped hoist when the latter is unintentionally vertically misaligned with the center of gravity of the pump unit.

摘要： A boiler gas flow distribution fin includes an elongated flow distribution fin protruding from a back wall of a flow distribution channel into a hot gas flow path from a boiler combustion chamber. The flow distribution fin can include a leading segment with a leading ridge, a medial segment with a medial ridge, and a trailing segment with a trailing ridge. A gap between the fin ridges and a set of convective fins in an adjacent flue passageway segment can vary from a larger gap at the leading ridge to a smaller gap at the trailing ridge, transitioning along the medial ridge. The flow distribution fin can aid in directing a hot gas flow from a combustion chamber into the flue passageway segment, resulting in a substantially balanced mass flow rate through each of a series of flue passageway sections.

摘要： An electric motor assembly for a submersible pump has a base and an end ring which together directly, flatly engage opposite ends of a lamination stack so that the stack is thus aligned with the base and the end ring. A shell is pressed over the lamination stack and the ends of the shell are roll-formed to grippingly engage shoulders on the base and the end ring while the stack is held in compression. The shell directly engages the outer cylindrical periphery of the laminations to establish a continuous ground path and also to preclude shifting of individual laminations. The base is molded of a synthetic resinous material and directly supports a sleeve bearing, and a plurality of fluid conduits in the base enable passage of coolant to the bearing during operation of the motor. In preferred forms, the base is provided with an edge for directly engaging one end of a series of pump stagings, and the base also has a shoulder for gripping engagement with a complementally formed edge of a pump casing.

摘要： A submersible pump has a cartridge of pump stages that are compressed between an inlet base and a discharge head as a pump casing surrounding the cartridge is roll-formed to complementally engage shoulders on the base and the head. The inner diameter of the casing presents a slight interference fit with each of the pump stages so that a diffuser on each stage is held in a stationary position during operation of the pump. The casing also provides a plurality of radially inwardly directed forces to maintain the stages in alignment with each other. Complete circumferential contact of the diffuser walls with the interior surface of the casing reduces interstage leaking such that pump efficiency is enhanced.

摘要： A float assembly for use in tanks, sumps or other liquid-containing vessels includes an elongated, upright, extruded support which maintains individual float switches at preselected heights. The support includes upright, elongated, recess-defining walls with a pair of flat, spaced, parallel sidewall portions that are configured to grippingly engage an outer, deformable insulative covering of a cord connected to the float switch. The cord may be grasped and pulled to an appropriate height, and is thereafter secured by the sidewall portions without the use of tools, fasteners or other components. In preferred forms, the recess-defining walls have a transverse, generally U-shaped configuration with an internal passageway for housing an upper portion of the cord between the float switch and an overlying junction box.

摘要： A fan assembly, which includes a centrifugal-type fan wheel mounted for rotation in, e.g., a scroll-like fan casing or a tubular fan casing is provided with a retractable fan inlet funnel which may be selectively positioned relative to the fan wheel between an extended position and a retracted position. In the extended position, the inlet funnel axially overlaps the inlet side of the fan wheel with substantially all the inlet air being directed into the fan wheel. In the retracted position, the inlet funnel is spaced away from the fan wheel to permit a portion of the fan wheel outlet air to recirculate to the inlet side of the fan wheel. Fan performance characteristics including the static pressure, the volume flow rate, the selection of a stable air flow operating point, and the fan wheel power requirements are conveniently and advantageously controlled by adjusting the inlet funnel position.In the preferred embodiment, the inlet funnel has a converging/diverging venturi shape and is movably connected to a truncated conical base by a linkage assembly. The assembly includes a plurality of links each of which has one end pivoted to the base and the other end pivotally connected to a support ring which is connected to the inlet funnel by struts. Pivotal movement of the links, either by a torque member or a lead-screw/nut arrangement, causes the inlet funnel to change its position relative to the fan wheel and thereby vary the fan performance.
摘要翻译：一种风扇组件，其包括安装用于旋转的涡旋式风扇壳体或管状风扇壳体的离心式风扇叶轮，其具有可伸缩风扇入口漏斗，其可相对于风扇叶片在延伸位置和缩回位置。在延伸位置，入口漏斗与风扇叶轮的入口侧轴向重叠，基本上所有入口空气被引导到风扇叶轮中。在缩回位置，入口漏斗与风扇叶轮间隔开，以允许风扇叶轮出口空气的一部分再循环到风扇叶轮的入口侧。风扇性能特征包括静压，体积流量，稳定气流工作点的选择以及风扇轮功率的要求通过调节入口漏斗位置来方便和有利地进行控制。在优选实施例中，入口漏斗具有会聚/发散的文氏管形状并且通过连杆组件可移动地连接到截头圆锥形基座。组件包括多个连杆，每个连杆的一端枢转到底座，另一端枢转地连接到支撑环，支撑环通过支柱连接到入口漏斗。通过扭矩构件或导螺杆/螺母装置，链节的枢转运动使得入口漏斗相对于风扇叶轮改变其位置，从而改变风扇性能。

摘要： A threaded lid for closing the opening in a pump housing having a body portion and a gripping formation defined by a ridge on the body portion having a central portion and projections extending beyond the central portion. A juncture between the central portion and each of the projections varies gradually from a rounded angle at one terminus of the juncture to a gently sloping ramp at the other terminus of the juncture, so that a simple elongated tool such as a stick may be placed between the projections of the gripping formation and rotated to loosen the lid, but not to tighten it. Furthermore, the mildly curved S-shape provides surfaces which conform to the hand to enable substantial manual loosening force to be applied comfortably to the lid, whereas the surfaces of the gripping formation engaged by the hand to tighten the lid are not conducive to the application of a substantial amount of manual force.
