阀门密封一直都是工厂项目以及工厂设备管理所关注的问题。因为结构以及使用的特殊性,阀门的密闭需要特别的注意。那么怎么在阀门使用的过程中更好的进行保养呢?接下来,上海良工代理就为大家分享一些关于阀门保养的心得。
Valve sealing has always been a concern of plant projects and plant equipment management. Because of the particularity of the structure and use, the sealing of the valve needs special attention. So how to better maintain the valve in the process of use? Next, Shanghai Lianggong agent will share some experience on valve maintenance.
1.阀盘上焊接的螺栓不宜太长,否则会因为螺栓过长而抵住阀体内流到,造成密封被“架空”,不能发挥密封作用;组装时应注意检查调整丝杆开度,保证密封面能紧密接合。
1. The bolt welded on the valve disc should not be too long, otherwise it will flow into the valve body because the bolt is too long, resulting in the seal being "overhead" and unable to play the sealing role; During assembly, pay attention to check and adjust the opening of the screw rod to ensure that the sealing surface can be closely connected.

2选择合适的调整垫,衬垫厚度应稍低于或等于阀盘密封面台阶高度,使软密封垫与阀盘密封面紧密贴合,处于同一个平面。
2. Select a suitable adjusting pad. The thickness of the pad shall be slightly lower than or equal to the step height of the valve disc sealing surface, so that the soft sealing pad and the valve disc sealing surface are closely fitted and in the same plane.
3为防止压紧螺母脱落,螺母旋紧后应作适当的放松处理。
3 in order to prevent the compression nut from falling off, the nut shall be properly loosened after tightening.
4.应考虑流体介质使用条件,选择适合介质要求的软密封垫,以免出现介质腐蚀或高温变形等影响使用。
4. The service conditions of fluid medium shall be considered and the soft sealing gasket suitable for the medium requirements shall be selected to avoid medium corrosion or high-temperature deformation.
5.当阀座密封面损坏较严重时,阀座可报废处理,阀芯经改进后仍可继续与同规格的阀座配套使用。
5. When the sealing surface of the valve seat is seriously damaged, the valve seat can be scrapped, and the valve core can still be used with the valve seat of the same specification after improvement.
6.调节阀门时应做好标记,避免猛开猛关,以免影响密封垫使用寿命。
6. Mark when adjusting the valve to avoid opening and closing violently, so as not to affect the service life of the gasket.
