外闸

Constant Flow Valve and the constant flow regulating valve are different:there is only one fixed flow valve valve from the valve directly feel before and after the differential pressure valve,the implementation of change in valve resistance action can be"direct action type variable resistance valve",闸阀;It should not regulate the flow line,so the use of Constant Flow Valve can not be implemented to change the total flow of energy to run,and this set the flow valve as there are no imports of expensive,in the past,domestic heating systems seldom used,and only at some central air conditioning system to see.

订流量阀和恒流量调节阀不同的是：定流量阀只需一个阀瓣，由这个阀瓣直接感受阀门的后后佳压，执行转变阀门阻力的动做，否成为"直动式变阻力阀"，facebook外白板，它没有能在线调节流量，研建课，因己运用定淌量阀无法实施改变合流量的节能运行，而且这种定流量阀海外不，入口的价钱昂贵，以来国内的供暖体系很少采用，只需在一些中央空调系统内见到。
