1、阀门起吊时,绳子不要系在手轮或阀杆上,以免损坏这些部件,应该系在法兰上。
1. When lifting the valve, the rope should not be tied to the handwheel or valve stem, so as not to damage these parts, it should be tied to the French.
2、安装前,应将阀门作一检查,核对规格型号,鉴定有无损坏,尤其对于阀杆。还要转动几下,看是否歪斜,因为运输过程中,最易撞歪阀杆。还要清除阀内的杂物。
2. Before installation, the valve should be inspected to check the specifications and models, and to identify whether there is any damage, especially for the stem. Turn it a few times to see if it's skewed, because it's the most prone to bump into the skewed stem during transportation. Also remove debris from the valve.
3、安装法兰气动阀门时,要注意对称均匀地把紧螺栓。阀门法兰与管子法兰必须平行,间隙合理,以免阀门产生过大压力,甚至开裂。对于脆性材料和强度不高的阀门,尤其要注意。须与管子焊接的阀门,应先点焊,再将关闭件全开,然后焊死。
3. When installing flange pneumatic valves, attention should be paid to tightening bolts symmetrically and evenly. Valve flange and pipe flange must be parallel, reasonable clearance, so as to avoid excessive pressure, or even cracking of the valve. Special attention should be paid to brittle materials and valves with low strength. Valves that need to be welded with pipes should be spot welded first, then all closures should be opened, and then welded to death.
4、安装螺口阀门时,应将密封填料(线麻加铅油或聚四氟乙烯生料带),包在管子螺纹上,不要弄到阀门里,以免阀内存积,影响介质流通。
4. When installing threaded valves, sealing fillers (linen with lead oil or PTFE raw material belt) should be www.fenqieji.net.cnwww.qiezhiji.net.cnwww.weishengzhiji.com.cnwww.gangxianwei.net.cn www.wushuichulii.cnwww.jiedixuanxian.cnwrapped on the threads of pipes, so as not to get into the valves, so as to avoid the accumulation in the valves and affect the flow of media.
5、对于阀门所连接的管路,一定要清扫干净。可用压缩空气吹去泥砂、氧化铁屑、焊渣等杂物。这些杂物,不但容易擦伤阀门的密封面,其中大颗粒杂物,还能堵死小阀门,使其失效。
5. For the pipelines connected by the valves, they must be cleaned. Compressed air can be used to blow away mud, sand, iron oxide, welding slag and other impurities. These impurities not only easily scratch the sealing surface of the valve, but also block the small valve and make it invalid.
