    Parker 流量控制閥
    Parker Flow Control Valves
    可調減壓閥 - 44系列 Adjustable Reducing Valves - Code 44

    派克的 Conflow 代號 44 - 可調減壓閥可提供預先設定的出口壓力, 而與進口壓力的變化無關, 從而降低水總管的壓力至適應于地下采礦除塵的水平。 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是一種可靠的可調節減壓閥,可提供預定的出口壓力,而與用于抑制地下礦井中粉塵的進水壓力的變化無關。 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.

    代碼44可以滿足包括低壓,高壓和超高壓在內的各種出口壓力,并允許對減壓范圍為124 bar的螺桿進行簡單的螺桿調節。 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.

    該閥以簡單的節流原理運行。 節流閥的調節是通過作用在彈簧加載活塞上的下游壓力來打開和關閉減壓閥來實現的。 因此,隨著入口壓力的波動,通過閥門的流量會減少和增加,以保持恒定的下游壓力。 設定壓力的調節是通過轉動調節螺釘來增加或減小彈簧壓縮力來進行的。 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,工作壓力高達206 bar。 Available in 1/2", 3/4", 1" and 1 1/4"” sizes and to a maximum working pressure of 206 bar.
