摘要： A sequencing valve and associated hydronic system are provided. The valve has first and second ports, which can be connected to a heat exchange device, and the valve is configured to selectively provide multiple fluids to the heat exchange device. For example, the valve can selectively connect hot and cold water supplies to the heat exchanger so that the heat exchanger can be used alternately to heat and cool air for a refrigeration system. The valve can include check valves that are adjusted by rotatable cams for controlling the flow of fluids into and out of the ports. Each cam can be mounted on a rotatable shaft so that the cams rotate to adjust the check valves between open and closed positions.

摘要： There are provided a fluid flow control valve and an orifice for a fluid flow control valve. The orifice defines two seats against which a diaphragm of the valve can be urged. Each seat defines a particular contour, including one or more channels, slots, and or protrusions that form flow control passages through which fluid flows between the diaphragm and the orifice. The orifice can be configured in either of two orientations so that either seat can be disposed toward the diaphragm. As the pressure differential across the valve increases, the diaphragm is urged more firmly against the seat facing the diaphragm and the diaphragm partially closes the flow control passages, thereby regulating the flow to a substantially uniform volumetric rate. The contours of the two seats can be the same, or each seat can be different to provide a unique controlled flow rate.

摘要： A fluid flow control valve comprises a housing defining a fluid flow passage extending longitudinally therethrough, the housing having opposite ends each defining an opening for flow into and out of the fluid flow passage, and an orifice and diaphragm disposed in the housing. The orifice has a seat at one end thereof facing the diaphragm. The diaphragm has one end face that opposes the seat of the orifice, the seat being configured such that one or more flow control passages are defined between the seat and the one end face of the diaphragm through which the fluid flows. The seat is contoured to include at least two different shapes of channels each promoting localized bending of the diaphragm at a different pressure differential, thereby permitting an expansion of the working pressure range to very low pressure differentials. The localized bending of the diaphragm can be modeled as a simple supported beam bending, which is well understood and readily predicted, thus making the prediction of the diaphragm movement more accurate than prediction of complex diaphragm deflections that occur in many prior flow control valves. Accordingly, the accuracy of the flow control valve can be improved over that of prior valves having complex diaphragm deflection modes.
摘要翻译：流体流量控制阀包括限定纵向延伸穿过其中的流体流动通道的壳体，所述壳体具有相对的端部，每个端部限定用于流入和流出流体流动通道的开口，以及设置在壳体中的孔口和隔膜。孔口在其一端面向隔膜的座椅。隔膜具有与孔口的座部相对的一个端面，座椅构造成使得一个或多个流动控制通道限定在阀座与流体流过的隔膜的一个端面之间。座椅的轮廓是包括至少两个不同形状的通道，每个通道促进隔膜在不同压差下的局部弯曲，从而允许工作压力范围扩展到非常低的压力差。隔膜的局部弯曲可以被建模为简单的支撑梁弯曲，这是很好的理解和容易预测的，因此使得隔膜运动的预测比在许多现有流量控制阀中发生的复杂隔膜偏转的预测更准确。因此，与具有复杂的膜片偏转模式的现有阀相比，可以提高流量控制阀的精度。
