閥門密封一直都是工廠項目以及工廠設備管理所關(guān)注的問題。因為結(jié)構(gòu)以及使用的特殊性，閥門的密閉需要特別的注意。那么怎么在閥門使用的過程中更好的進行保養(yǎng)呢？接下來，上海良工代理就為大家分享一些關(guān)于閥門保養(yǎng)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.閥盤上焊接的螺栓不宜太長，否則會因為螺栓過長而抵住閥體內(nèi)流到，造成密封被“架空”，不能發(fā)揮密封作用；組裝時應注意檢查調(diào)整絲桿開度，保證密封面能緊密接合。
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選擇合適的調(diào)整墊，襯墊厚度應稍低于或等于閥盤密封面臺階高度，使軟密封墊與閥盤密封面緊密貼合，處于同一個平面。
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為防止壓緊螺母脫落，螺母旋緊后應作適當?shù)姆潘商幚怼?/div>
3 in order to prevent the compression nut from falling off, the nut shall be properly loosened after tightening.
4.應考慮流體介質(zhì)使用條件，選擇適合介質(zhì)要求的軟密封墊，以免出現(xiàn)介質(zhì)腐蝕或高溫變形等影響使用。
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.當閥座密封面損壞較嚴重時，閥座可報廢處理，閥芯經(jīng)改進后仍可繼續(xù)與同規(guī)格的閥座配套使用。
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.調(diào)節(jié)閥門時應做好標記，避免猛開猛關(guān)，以免影響密封墊使用壽命。
6. Mark when adjusting the valve to avoid opening and closing violently, so as not to affect the service life of the gasket.
