摘要： The invention provides a valve stem locking assembly for releasably locking a threaded fastener relative to a valve stem of a quarter-turn valve such as a ball valve. The assembly includes a handle defining an opening shaped to engage a corresponding shape of the valve stem to preclude relative rotation therebetween while allowing relative motion therebetween along the longitudinal axis of the valve stem. A standard nut engages the handle and is threaded onto the valve stem for movement relative to the valve stem along the axis. A spring biases the nut and the handle into relative rotation resisting engagement with each other. A camming mechanism, defined by the handle and the chamfer of the nut, is biased by the spring to prevent relative rotation therebetween until a desired torque about the axis is applied to the nut relative to the handle. When the nut is turned, the camming mechanism overcomes the rotation resisting engagement and pushes the handle along the valve stem axis against the bias of the spring. The nut then becomes free to rotate relative to the handle until the nut and the handle reengage.
摘要翻译：本发明提供了一种阀杆锁定组件，用于相对于诸如球阀的四分之一转阀的阀杆可释放地锁定螺纹紧固件。组件包括限定开口的手柄，该开口被成形为接合阀杆的对应形状，以防止其间的相对旋转，同时允许其间沿着阀杆的纵向轴线的相对运动。标准螺母与手柄接合并且被螺纹连接到阀杆上，用于沿着轴线相对于阀杆运动。弹簧使螺母和手柄相互抵抗接合。由手柄和螺母的倒角限定的凸轮机构由弹簧偏置以防止其间的相对旋转，直到围绕轴线的期望扭矩相对于手柄施加到螺母。当螺母转动时，凸轮机构克服旋转阻力接合并克服弹簧的偏压沿阀杆轴线推动手柄。然后，螺母相对于把手自由旋转，直到螺母和手柄重新接合。

摘要： A pilot valve for connecting a source of fluid under pressure to an actuator where the pilot valve may be connected to the actuator in any of 360.degree. of rotation so that the fluid connections may be made from any desired direction. Further disclosed is a coupling adapter joining the pilot valve to the actuator with passages so arranged in the adapter that 180.degree. rotation of the coupling adapter reverses the fluid flow connections between the pilot valve and the actuator simultaneously exposing indicia indicating the condition. Still further disclosed is a spring return manual override that is slotted to enable operation by a coin and has a mating slot in the pilot valve body allowing locking in the override position by insertion of a coin or similar device. A ball valve actuator is described as an actuator device.

摘要： An explosion-proof limit switch having an explosion proof housing that mounts to the side of a rotary control device with actuation pins extending through annular seals to be driven by a cam on the rotary shaft of the control device. Switching units mounted inside the explosion-proof housing are mounted on a fixed pivot at a first mounting point and held resiliently at a second mounting point in a double acting adjustable spring assembly which acts both to adjusting the switching point and to absorbing excessive impact or actuating throw so as to reduce possibility of damage.

摘要： An improved control valve to control very low rates of flow having a valve body housing a throttle mechanism. The throttle mechanism comprising a bore and throttle plunger, having a helical exterior groove, sized with an annular passage therebetween. The size of the cylindrical passage is selected and held within limits so that media of a chosen viscosity maintains fully developed laminar conditions as it enters and exits the valve, by keeping the Reynolds Number under 4000. The flow rate is controlled by varying the distance that the throttle plunger extends into the bore. Because the valve operates under constant laminar conditions this varying distance yields linear results between the length of engagement of the throttle plunger in the bore and the flow rate resulting in an increased accuracy control valve.
摘要翻译：一种改进的控制阀，用于控制具有容纳节流机构的阀体的非常低的流量。节流机构包括孔和节流柱塞，其具有螺旋形外部凹槽，其尺寸为其间的环形通道。圆柱形通道的尺寸被选择并保持在极限内，使得所选择的粘度的介质通过保持雷诺数低于4000时，保持其进入和离开阀门时的完全发展的层状条件。流量通过改变距离节流柱塞延伸到孔中。由于阀在恒定的层流条件下运行，所以这种变化的距离在节流柱塞在孔中的接合长度与流速之间产生线性结果，导致增加的精度控制阀。

摘要： An improved latch mechanism for a fluid flow control valve. The latch mechanism having a latch body, a spring, a plunger and a thumb release lever for disengagement of the plunger. The latch mechanism is attached to a valve handle which controls the fluid flow rate through the valve. Provided with the latch, the handle and thereby the valve can be locked into either a closed or open position at the limits of the valves' necessary rotation thereby preventing inadvertent opening or closing of the valve. The thumb release lever disengages the plunger with detent notches provided in the valve body allowing safe and efficient single handed operation of the handle and latch mechanism even under adverse environmental conditions when operator dexterity is impaired by gloves.

摘要： A ball valve is described having a latching handle with a latch plate having raised lugs that engage the handle, a latch mechanism or both to act as detent stops in predetermined rotational positions. A flat spring rolled at one end urges the latch mechanism into the latched position and a pivoting cap secured to the handle is latched by simultaneous action of the latch mechanism to block access to a nut securing the handle assembly. Provision is made for attaching a padlock.
