高压阀门的九个维护的小知识
Nine maintenance tips for high pressure valves
长期以来,国内的大多数行业是以新换旧,把换下的阀门当废品扔掉或卖掉.特别是多用带法兰盘阀门的行业.而对换下的高压、高温、大阀门想修,但不知道怎样修。多数还停留在手工修理阶段。可以说的阀门维修业中,浪费与可获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.
高压阀门维护的小知识:
Tips on high pressure valve maintenance:
1、使用维护的目的,在于延长阀门寿命和保障启闭可靠。
1. The purpose of use and maintenance is to prolong the service life of the valve and ensure reliable opening and closing.
2、阀杆螺纹,经常与阀杆螺母摩擦,要涂一点黄干油、二硫化钼或石墨粉,起润滑作用
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、不经常启闭的阀门,也要定期转动手轮,对阀杆螺纹添加润滑剂,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、室外阀门,要对阀杆加保护套,以防雨、雪、尘土锈污。
4. For outdoor valves, the valve rod shall be protected from rain, snow, dust and rust.
5、如阀门系机械待动,要按时对变速箱添加润滑油。
5. If the valve is mechanically operated, add lubricating oil to the gearbox on time.
6、要经常保持阀门的清洁。
6. Always keep the valve clean.
7、要经常检查并保持阀门另部件完整性。如手轮的固定螺母脱落,要配齐、不能凑合使用,否则会磨园阀杆上部的四方,逐渐失去配合可靠性,乃不能开动。
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、不要依靠阀门支持其它重物,不要在阀门上站立。
8. Do not rely on the valve to support other heavy objects, and do not stand on the valve.
9、阀杆,特别是螺纹部分,要经常擦拭,对已经被尘土弄脏的润滑剂要换成新的,因为尘土中含有硬杂物,容易磨损螺纹和阀杆表面,影响使用寿命。
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.
