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 connection for joining an actuator to a valve comprising providing at least two flanged pins each in the body of the valve, providing at least two mating holes in a body of the actuator, the mating holes being aligned with the pins, providing a tapped hole transverse to each of the mating holes, the valve body being joined to the actuator such that the pins mate slidably with the holes, with set screws in the tapped holes engaging the flanged pins to axially tension the pins to draw the valve body into physical contact with the actuator.

摘要： A double-acting, piston driven actuator for providing a double action rotary powered output, having a stepped bore housing a double acting piston having a larger diameter end and a smaller diameter end therein; a three way valve selectively to supply pressurized fluid to the larger end the pressurized fluid continuously supplying the pressurized fluid to the smaller diameter portion of the bore. An optional safety mechanism having a spring biased second piston for biasing the double acting piston to a safe position upon failure of the pressurized fluid delivery system is also provided.
摘要翻译：一种用于提供双作用旋转动力输出的双作用式活塞驱动致动器，具有一个阶梯孔，其具有一个具有较大直径端和一个较小直径端的双作用活塞; 选择性地将加压流体供应到较大端的三通阀，加压流体将加压流体连续地供应到孔的较小直径部分。还提供了一种可选的安全机构，其具有弹簧偏压的第二活塞，用于在加压流体输送系统失效时将双作用活塞偏置到安全位置。
