我广使用一台匈牙利进口的50米~3/时制氧机。氧压机三级出气阀的阀体与阀座采用螺纹连接,阀芯是以阀座定位的。由于螺纹连接不能有效地保证阀体与阀座的同心,引起阀芯对阀体的偏心,使接触不良,在冲击载荷作用下,阀体很快损坏,严重时曾在一个班中换过三个阀芯。由于阀体损坏,导致二级压力升高,使二级安全阀动作,多次造成被迫停车更换阀体,给生产带来很大损失。
I use a widely imported Hungarian 50 meters ~ 3 / hour oxygen generator. Oxygen compressor outlet valve body and the valve seat with threaded connection, the valve seat is located. As the thread connection can not effectively ensure the concentricity of the valve body and the seat, causing the valve body eccentric to the valve body so that the contact is poor. Under the action of impact load, the valve body is damaged rapidly. In severe cases, A spool. As the valve body is damaged, the secondary pressure rises, causing the secondary safety valve to move. This results in being forced to stop and replace the valve body many times, which brings great losses to the production.
