可调减压阀 - 44系列 Adjustable Reducing Valves - Code 44

派克的 Conflow 代号 44 - 可调减压阀可提供预先设定的出口压力, 而与进口压力的变化无关, 从而降低水总管的压力至适应于地下采矿除尘的水平。 Parker Conflow's Code 44 is a reliable, adjustable reducing valve that provides a pre-determined outlet pressure irrespective of variation of inlet pressure for dust suppression in underground mines.

派克Conflow的Code 44是一种可靠的可调节减压阀，可提供预定的出口压力，而与用于抑制地下矿井中粉尘的进水压力的变化无关。 Parker Conflow's Code 44 is a reliable, adjustable reducing valve that provides a pre-determined outlet pressure irrespective of variation of inlet water pressure for dust suppression in underground mines.

代码44可以满足包括低压，高压和超高压在内的各种出口压力，并允许对减压范围为124 bar的螺杆进行简单的螺杆调节。 Code 44 caters for a full range of outlet pressures including low, high and extra high and allows for simple screw adjustment of pressure reduction range up to 124 bar.

该阀以简单的节流原理运行。 节流阀的调节是通过作用在弹簧加载活塞上的下游压力来打开和关闭减压阀来实现的。 因此，随着入口压力的波动，通过阀门的流量会减少和增加，以保持恒定的下游压力。 设定压力的调节是通过转动调节螺钉来增加或减小弹簧压缩力来进行的。 The valve operates on a simple throttling principle. The throttle adjustment is achieved by the downstream pressure acting on a spring-loaded piston to open and close the reducing valve. Thus the flow through the valve is reduced and increased as the inlet pressure fluctuates, in order to maintain constant downstream pressure. Adjustment of the set pressure is carried out by increasing or reducing the spring compression by turning the adjusting screw.

提供1/2“，3/4”，1“和1 1/4”“尺寸，工作压力高达206 bar。 Available in 1/2", 3/4", 1" and 1 1/4"” sizes and to a maximum working pressure of 206 bar.
