高壓閥門的九個維護的小知識
Nine maintenance tips for high pressure valves
長期以來，國內的大多數行業是以新換舊，把換下的閥門當廢品扔掉或賣掉．特別是多用帶法蘭盤閥門的行業．而對換下的高壓、高溫、大閥門想修，但不知道怎樣修。多數還停留在手工修理階段。可以說的閥門維修業中，浪費與可獲得的效益都是巨大的。
For a long time, most domestic industries trade in the new for the old, and throw away or sell the replaced valves as waste. Especially in the industries with multi-purpose valves with flanges, they want to repair the replaced high-pressure, high-temperature and large valves, but do not know how to repair them. Most of them are still in the manual repair stage. It can be said that in China's valve maintenance industry, waste and benefits are huge.
高壓閥門維護的小知識：
Tips on high pressure valve maintenance:
1、使用維護的目的，在于延長閥門壽命和保障啟閉可靠。
1. The purpose of use and maintenance is to prolong the service life of the valve and ensure reliable opening and closing.
2、閥桿螺紋，經常與閥桿螺母摩擦，要涂一點黃干油、二硫化鉬或石墨粉，起潤滑作用
2. The thread of the valve rod often rubs with the valve rod nut. It should be coated with a little yellow dry oil, molybdenum disulfide or graphite powder for lubrication
3、不經常啟閉的閥門，也要定期轉動手輪，對閥桿螺紋添加潤滑劑，以防咬住。
3. For valves that are not frequently opened and closed, the hand wheel shall also be rotated regularly to add lubricant to the stem threads to prevent seizure.
4、室外閥門，要對閥桿加保護套，以防雨、雪、塵土銹污。
4. For outdoor valves, the valve rod shall be protected from rain, snow, dust and rust.
5、如閥門系機械待動，要按時對變速箱添加潤滑油。
5. If the valve is mechanically operated, add lubricating oil to the gearbox on time.
6、要經常保持閥門的清潔。
6. Always keep the valve clean.
7、要經常檢查并保持閥門另部件完整性。如手輪的固定螺母脫落，要配齊、不能湊合使用，否則會磨園閥桿上部的四方，逐漸失去配合可靠性，乃至不能開動。
7. Always check and maintain the integrity of other parts of the valve. If the fixed nut of the hand wheel falls off, it shall be fully equipped and cannot be used properly, otherwise the four sides on the upper part of the valve stem will be grinded, and the reliability of the coordination will be gradually lost, and even the operation will not be started.
8、不要依靠閥門支持其它重物，不要在閥門上站立。
8. Do not rely on the valve to support other heavy objects, and do not stand on the valve.
9、閥桿，特別是螺紋部分，要經常擦拭，對已經被塵土弄臟的潤滑劑要換成新的，因為塵土中含有硬雜物，容易磨損螺紋和閥桿表面，影響使用壽命。
9. The valve rod, especially the threaded part, should be wiped frequently, and the lubricant that has been soiled by dust should be replaced with a new one, because the dust contains hard debris, which is easy to wear the thread and valve rod surface and affect the service life.
