LH45X-16微阻限流止回閥
| 產品介紹 |
|
一、結構及用途 structure and purpose 該閥用于水泵出口控制水泵的實際工作揚程 ,以限制水泵的工作流量,限制水泵電機負載,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.
