不锈钢闸阀维修，是不锈钢阀门维修中的一个常见种类，江阴市欧雷斯阀门维修厂在多年的不锈钢闸阀维修中，常见的损坏情况有：阀瓣阀座拉伤、阀瓣阀座冲刷、阀瓣阀座腐蚀麻点，阀杆填料部位腐蚀；导致阀门内密封泄露及阀门开关不灵活，以下不锈钢闸阀维修案例，是使用在有腐蚀的化工原料上的不锈钢闸阀，本批闸阀同时出现了：阀瓣阀座拉伤、阀瓣阀座冲刷、阀瓣阀座腐蚀麻点这类损坏，阀门外表被覆盖了一层油漆；本批阀门材质为304，我单位针对这个情况，对阀门拟订了维修重点：
1 阀门外表除油漆
2 阀门内部件及阀体，阀杆去除杂质，恢复本体材料颜色，便于焊接
3 对局部损坏部位进行堆焊，对大面积损坏阀瓣阀座进行整面堆焊
4 用欧雷斯OLS-TMX400型台式磨削机，对焊接层进行磨削留余量0.1-0.5mm
5 欧雷斯OLS-TMX400型台式研磨机，对磨削好的阀瓣阀座进行粗、中、细研磨
其他细节不尽细说，以下是我公司对不锈钢闸阀维修的效果比较图片，本批阀门气密试验1.6Mpa达到零泄露
Stainless steel gate valve repair is a common kind of stainless steel valve repair, stainless steel gate valve repair common damage: disc seat strain, disc seat, disc seat corrosion pitting, corrosion stem packing PARts; Results in a sealing in the valve leakage and the valve switch is not flexible, the stainless steel gate valve repair case, is used in chemical raw materials of corrosion were stainless steel gate valve, this batch of gate valves also APPeared: the disc seat strain, disc seat washout, disc seat corrosion pitting such damage, the valve appearance are covered with a layer of paint; This valve material is 304, my unit according to the situation, the valve to formulate the maintenance key: 1 body appearance in addition to paint 2 items within the valve and valve, the valve stem to remove impurities, restoring ontology material color, facilitate welding 3 surfacing welding was carried out on the local damage, finishing welding was carried out on the large area of damage to the disc seat 4 with the OLS - TMX400 desktop grinding machine, grinding leave allowance for welding layer of 0.1-0.5 mm 5 o les OLS - TMX400 bench grinder, good grinding disc seat for coarse, medium and fine grinding Other details not in detail, the following is my company the maintenance effect comparing pictures of stainless steel gate valve, this valve air test 1.6 Mpa to achieve zero leakage
