風(fēng)道閥門

　　通風(fēng)系統(tǒng)的風(fēng)道閥門依其作用不同可分為風(fēng)道密閉閥、風(fēng)道調(diào)節(jié)閥、風(fēng)道止回閥。風(fēng)道密閉閥的作用是在管道中隔斷或切斷氣流。隔斷氣流時要求閥門內(nèi)泄露為零，切斷氣流時則允許有一定的泄漏量。風(fēng)道調(diào)節(jié)閥的作用是在通風(fēng)系統(tǒng)中起平衡流量調(diào)節(jié)作用，例如維持個系統(tǒng)之間的壓力、各廠房內(nèi)的溫度和濕度等，為了達(dá)到此目的我們需要根據(jù)起流量特性對風(fēng)道調(diào)節(jié)閥進(jìn)行控制。通風(fēng)蝶閥為風(fēng)道密閉閥，近年來隨著工農(nóng)業(yè)的發(fā)展而應(yīng)用較多。為此，我廠工程技術(shù)人員開發(fā)設(shè)計(jì)了的不同規(guī)格的系列蝶閥供用戶選擇。

　　The air channel valve of a ventilating system covers air channel closing valve air channel adiusting valve and air channel check valve which are of different actions The action of the air channel closing valve comes at cutting offor isolating the airfIow inside of the Pipeline with the inte rnalleak of the valve required to be ze ro at isoIating the airflow while a certain leakage allowed at cutting off the airfIow The air channel adiusting valve acts at flow balance adiusting in the ventilating system，such as to keep the Pressure between the svstems and the temperature and humidifv inside of the factorv house，and，to qet this Purpose，the valve needs to be controlledupon the flowproperty The ventilating butterfly valve is to be the air channel closing valve and much more applied along with the development of both indusfry and agriculture in the recent years The refore the technicians in this Co have designed and developed series butterfly valves in different specifications for users to select.
