摘要： Liquid flow through a conduit in a branch of a hydronic system provided with a balancing valve and, in series therewith, a metering valve to obtain a desired rate of flow in the branch is regulated by positioning immediately adjacent an accelerated-flow zone in the metering valve in the conduit a pitot having an upstream side directed upstream against a direction of flow through the conduit and a downstream side directed downstream in the flow direction. The metering valve is settable in a plurality of predetermined positions each corresponding to a respective flow cross section through the conduit. A differential pressure meter is connected to both sides of the pitot, the one of the predetermined valve positions is selected that gives a near full-range reading on the meter, and the metering valve is set in this selected one position. The pressure-differential reading on the meter is monitored and the balancing valve is adjusted to regulate flow therethrough until the read pressure corresponds to a level itself corresponding to the desired rate of flow in the branch.

摘要： Simple APCV, ADPCV and PICV's are provided. The APCV's are referenced to the atmosphere and control the gauge pressure, either upstream or downstream. The ADPCV's are the same as the APCV's, differing in that they are not referenced to the atmosphere. They are instead referenced to a second point in the fluid flow system and control the differential pressure. The PICV's are control valves connected in series with ADPCV's and control the fluid flow rate through the valve independently of variations in the line pressure. A preferred APCV has a valve body (1) with connections for a single-phase fluid line and a flow passage between the inlet (2) and the outlet (3) of said fluid line, with an opening having a defined seat orifice (7) intersecting the flow passage. A moveable assembly, comprising a disk (5) or cup is connected to a pressure sensing member (4), having essentially the same effective surface area. The moveable assembly, is biased by a force, and is free to automatically move to any intermediate position between fully open and closed, producing a desired outlet pressure which minus the reference pressure, times the effective surface area of the disk or cup generates an opposing force equal to the biasing force.
摘要翻译：提供简单的APCV，ADPCV和PICV。 APCV参考大气层，控制压力表，上游或下游。 ADPCV与APCV相同，不同之处在于它们不参与气氛。它们代替流体流动系统中的第二个点，并控制差压。 PICV是与ADPCV串联连接的控制阀，可以独立于管路压力的变化来控制通过阀门的流体流量。优选的APCV具有阀体（1），其具有用于单相流体管线的连接和在所述流体管线的入口（2）和出口（3）之间的流动通道，具有限定的阀座孔口（7））与流动通道相交。包括盘（5）或杯的可移动组件连接到压力感测构件（4），具有基本上相同的有效表面积。可移动组件被力偏压，并且自由地自动地移动到完全打开和关闭之间的任何中间位置，产生所需的出口压力减去参考压力，乘以盘或杯的有效表面积产生相对的力等于偏置力。

摘要： Described is a torque amplifying device that is of centrifugal or gyroscopic type and has a unidirectional drive or drives. This device is used to control the body of a controlled object, such as an airplane, helicopter, land vehicle, cargo handling mechanism, earth moving machine or maritime device or vehicle. The torque amplifying devices are designed so that they supply a torque (momentum) to the body of the controlled object where it is connected. Thereby, the orientation or weight distribution of the body is controlled. The orientation is achieved without resorting to the physical properties of the surrounding environment (ground, water or air). Thus, it can apply a torque to this body in pitch, roll and/or yaw, so that it achieves the position or weight distribution the control system is calling for. The duration of the torque can be unlimited, until the conditions that produce it are intentionally changed.

摘要： Valves, particularly useful for controlling flow of heat transfer fluids in various heating, air conditioning and ventilation systems, are provided. The valves are of the curtain valve type and operate at very low torque and provide easy assembly and repair. The valve or actuator has an adjustment for the flow coefficient. A disclosed valve comprises a valve body having an inside surface, an inlet port comprised of an opening through the inside surface and enabling fluid flow into the valve body, an outlet port comprised of an opening through the inside surface and enabling fluid flow from the valve body, and a curtain valve closure. The closure adjustably controls fluid flow through the outlet port and is of a modular design including a flexible diaphragm held in an insert positioned at least partially within the outlet port. The insert has at least one dimension larger than a mating surface on the internal surface of the valve body. In this manner the insert is secured without fasteners and properly oriented within the outlet port, facilitates easy assembly and enables the use of low-torque actuators. The valve can employ a radially- and axially-moveable shoe to assure tight close off.

摘要： The invention provides valves of the type employing a differential pressure regulator and a characterized valve with a mechanism to enhance control of fluid flow independently of system pressure. The valves of the invention are especially suitable for HVAC applications, and provide operation with improved accuracy over a greater flow range with a reduced risk of hunting. In one preferred aspect, the invention provides improvements by the employment in the differential pressure regulator of a diaphragm with a cup arranged to provide a small leakage, thereby dampening the response of the regulator. In another aspect, a baffle is provided to protect the downstream side of a control disk forming part of the differential pressure regulator.
