SJ1000X限流止回閥
 

一、結構及用途 structure and purpose

      該閥用於水泵出口控製水泵的實際工作揚程 ,以限製水泵的工作流量,限製水泵電機負載,使水泵在較高效率狀態下工作,防止水泵電機在低揚程、大流量、低效率時發生過載現象,防止超額定電流燒壞水泵電機現象發生,同時起到一定節能效果。安裝、維護、調試、檢查方便,使用壽命長,同時具有緩閉清聲止回閥功能。

This valve is used at a water pump's outlet to control the real working head of the pump so as to limit the working flow and the motor's load of it,make the pump working in a higher efficiency, prevent the motor from being overloaded in case if a low head,a big flow or a low efficiency and from being burnt due to an extra-rated cu r rent,with a certain energy saving effect Easy installation,maintenance,adjustment and check,long duration and of the function to be a slowly closed silencing check valve.
