結(jié)構(gòu)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(tài)下工作,防止水泵電機在低揚程、大流量、低效率時發(fā)生過載現(xiàn)象,防止超額定電流燒壞水泵電機現(xiàn)象發(fā)生,同時起到一定節(jié)能效果。安裝、維護、調(diào)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. |
