【詳細說明】
sd341x通風蝶閥 我公司生產的通風蝶閥采用鋼板焊接制造,具有結構尺寸短,重量輕,安裝方便等特點。該閥驅動力矩小,啟閉靈活,操作方便。閥體上設置油密封擋圈,密封副之間無可見間隙,泄漏率小。蝶板與閥體間的膨脹間隙大,能有效防止因熱漲冷縮造成的卡死現象。本閥可配備多種驅動裝置,如手動裝置、蝸輪傳動裝置、氣動裝置、電動裝置。通風蝶閥廣泛用于治金、師化、電力、建材、礦山等工業管線,對介質氣體氣控制或調節作用。 my corporation the person who produces the ventilation butterfly valve uses the steel plate welding to be made , and it is short to possess the structure size , and weight is light , and installs conveniently waiting for the characteristics . this valve drive moment of force is small , and opens and close nimblely , and it is convenient to operate . setting up oil in the valve aspect seals up the fender circle , and it is thus clear that not having between the close sub the interval , the leakage rate is small . between butterfly board and valve aspect expands that the interval is big , and can effectively prevent because of heat up to rise cold to contract ka si s appearance that cr-eates . this valve can be provided many kinds of drives , if the hand moves device and worm gear gearing , pneumatic device and motor-driven device . ventilation butterfly valve such as is extensively used to rule the jin shiization , power and is built material and mine etc at the industry pipes and power lines , to medium gas control or regulating action .
