德国BURKERT电磁阀阀门泄露的焊接加工步骤原理有哪些？
德国BURKERT电磁阀*种情况是：脏物杂质落到密封面上，将密封面垫住，造成阀芯与阀座间有间隙，从而阀门渗漏。消除这种故障的方法就是清除掉落到密封面上的脏物及杂质，般在锅炉准备停炉大小修时，做安全门跑砣试验，如果发现漏泄停炉后都进行解体检修。如果是点炉后进行跑砣试验时发现安全门漏泄，估计是这种情况造成的，可在跑砣后冷却20分钟后再跑舵次，对密封面进行冲刷。二种情况是密封面损伤。造成密封面损伤的主要原因有以下几点：是密封面材质不良。目前使用YST103通用钢焊条堆焊加工的阀芯密封面效果就比较好。二是检修差，阀芯阀座研磨的达不到标准要求，消除这种故障的方法是根据损伤程度采用研磨或车削后研磨的方法修复密封面。阀门泄露的焊接加工。
以下是参考译文：
The first kind of circumstance is: dirt to seal surface impurities, the sealing surface mat, causing a gap between valve core and valve seat, valve leakage. Method of eliminating the fault is cleared dropped a seal surface dirt and impurities, general big improvements in boiler for boiler stop, first do exit lead test run, if leakage is found after the furnace for overhauling. If it is a point after the furnace leakage found in testing the run lead the security, estimation is caused by this kind of situation, can be in running tuo cooling after 20 minutes after rudder, scour on sealing surface. The second is the sealing surface damage. The main reason for the sealing surface damage has the following points: one is the bad sealing surface material. Currently using YST103 general steel electrode welding processing of valve core sealing surface effect is good. Second, poor quality of maintenance, the valve core seat grinding can not meet the quality standard requirement, method of eliminating the fault according to the damage degree are grinding or turning the sealing surface grinding of repair methods
