　　短长度法兰蝶阀，短体法兰蝶阀是用圆盘式启闭件往复回转90°左右来开启、关闭或调节介质流量的一种阀门，阀板与阀轴的高精度加工确保了持久有效的负载传输

　　Imported short length flange butterflyvalve, short body flange butterfly valve is a type of valve that uses a disctype opening and closing element to rotate back and forth by about 90 ° to open, close, or adjust the medium flow rate. The high-precisionprocessing of the valve plate and valve shaft ensures long-lasting andeffective load transmission

　　进口短体法兰蝶阀特点

　　蝶阀具有调节及密封性能好、阻力小、启闭迅速

　　尺寸紧凑、重量轻，占有空间小的优势，取代传统的闸阀和截止阀，

　　不可忽视的蝶阀安装要点Main pointsof installation butterfly valve

　　1、要求使用对焊法兰，不建议采用平焊法兰，因为钢管伸进平焊法兰，容易碰到阀板，影响阀板自由启闭Recommend to use butt welding flange. Do not use flat welding flangebecause steel pipe can easily meet disc to affect opening and closing freelydisc if steel pipe enter flat welding flange.

　　2、确认法兰尺寸必须允许阀板自由转动，法兰内径不能过小或过大 The inner diameter of flange can't be too small or too big and mustconfirm the dimension of flange so that the disc can turn free.

　　3、蝶阀装上后不允许再焊接法兰，以免tang伤衬圈 For avoiding scalding the seat, do not weld flange after thebutterfly valve was installed in pipe.
