結(jié)構(gòu)及用途 structure
and purpose
該閥用于水泵出口控制水泵的實(shí)際工作揚(yáng)程
,以限制水泵的工作流量,限制水泵電機(jī)負(fù)載,使水泵在較高效率狀態(tài)下工作,防止水泵電機(jī)在低揚(yáng)程、大流量、低效率時(shí)發(fā)生過載現(xiàn)象，防止超額定電流燒壞水泵電機(jī)現(xiàn)象發(fā)生，同時(shí)起到一定節(jié)能效果。安裝、維護(hù)、調(diào)試、檢查方便，使用壽命長(zhǎng)，同時(shí)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. |
