閥門作為流體輸送系統(tǒng)中的控制部件，在石油化工、給排水、電力等眾多領域起著調節(jié)、控制流體流量、壓力和流向的關鍵作用。而閥門是否需要定期潤滑，答案是肯定的。定期合理的潤滑，對于閥門的正常運行、延長使用壽命、保障系統(tǒng)安全穩(wěn)定至關重要，以下將深入探討其原因和相關要點。

　　Valves, as control components in fluid transportation systems, play a crucial role in regulating and controlling fluid flow, pressure, and direction in various fields such as petrochemicals, water supply and drainage, and electricity. The answer to whether valves need regular lubrication is yes. Regular and reasonable lubrication is crucial for the normal operation of valves, extending their service life, and ensuring system safety and stability. The following will explore the reasons and related points in depth.

　　閥門需要定期潤滑的原因

　　The reason why valves need regular lubrication

　　1.減少摩擦與磨損

　　1. Reduce friction and wear

　　閥門的運行依賴于內部多個部件的相對運動，如閘閥的閘板升降、球閥的球體旋轉、截止閥的閥桿上下移動等。在這些部件的運動過程中，金屬與金屬、金屬與非金屬之間會產(chǎn)生摩擦。若缺乏潤滑，摩擦阻力會顯著增大，不僅增加了閥門操作的扭矩，導致開關困難，還會加速部件表面的磨損。長期高摩擦狀態(tài)下運行，閘板、閥桿等關鍵部件的表面會出現(xiàn)劃痕、凹坑，甚至變形，嚴重影響閥門的密封性能和使用壽命。定期潤滑能夠在部件表面形成一層油膜，有效隔離摩擦面，降低摩擦系數(shù)，減少磨損，使閥門操作更加輕松順暢。

　　The operation of a valve relies on the relative motion of multiple internal components, such as the gate lifting of a gate valve, the ball rotation of a ball valve, and the up and down movement of the stem of a globe valve. During the movement of these components, friction occurs between metals and between metals and non metals. If there is a lack of lubrication, the frictional resistance will significantly increase, which not only increases the torque of valve operation, causing difficulty in opening and closing, but also accelerates the wear of component surfaces. Long term operation under high friction conditions can cause scratches, dents, and even deformation on the surfaces of key components such as gate plates and valve stems, seriously affecting the sealing performance and service life of the valve. Regular lubrication can form an oil film on the surface of the component, effectively isolating the friction surface, reducing the friction coefficient, minimizing wear, and making valve operation easier and smoother.

　　2.防止部件銹蝕

　　2. Prevent component corrosion

　　閥門通常工作在各種復雜的環(huán)境中，空氣中的濕氣、腐蝕性氣體，以及流體介質中的化學物質等，都可能對閥門的金屬部件造成腐蝕。特別是在濕度較大的環(huán)境，或者輸送含有酸堿等腐蝕性介質時，金屬部件極易生銹。而潤滑脂具有良好的密封和防護性能，在對閥門進行潤滑時，潤滑脂會填充在部件的縫隙和表面，形成一道防護屏障，阻止水分、腐蝕性物質與金屬直接接觸，從而有效防止部件銹蝕，保持閥門部件的完整性和機械性能。

　　Valves typically operate in various complex environments, where moisture in the air, corrosive gases, and chemicals in fluid media can all cause corrosion to the metal components of the valve. Especially in environments with high humidity or when transporting corrosive media containing acid and alkali, metal parts are prone to rusting. Lubricating grease has good sealing and protective properties. When lubricating valves, lubricating grease will fill the gaps and surfaces of components, forming a protective barrier to prevent moisture, corrosive substances, and direct contact with metals, effectively preventing component corrosion and maintaining the integrity and mechanical performance of valve components.

　　3.確保密封性能

　　3. Ensure sealing performance

　　良好的密封是閥門正常工作的關鍵，尤其是在輸送易燃、易爆、有毒有害介質的系統(tǒng)中，密封失效可能引發(fā)嚴重的安全事故。閥門的密封部件，如密封圈、填料等，在長期運行過程中，會因摩擦、老化等因素導致密封性能下降。定期潤滑能夠減少密封部件與其他部件之間的摩擦，降低磨損程度，減緩密封部件的老化速度。同時，一些特殊的潤滑脂還具有一定的膨脹和填充作用，能夠彌補密封部件因磨損產(chǎn)生的微小間隙，進一步增強閥門的密封性能，防止介質泄漏。

　　Good sealing is the key to the normal operation of valves, especially in systems that transport flammable, explosive, toxic and harmful media. Seal failure may cause serious safety accidents. The sealing components of valves, such as sealing rings and packing, may experience a decrease in sealing performance due to factors such as friction and aging during long-term operation. Regular lubrication can reduce friction between sealing components and other components, lower the degree of wear, and slow down the aging rate of sealing components. At the same time, some special lubricating greases also have certain expansion and filling functions, which can compensate for the small gaps caused by wear of sealing components, further enhance the sealing performance of valves, and prevent medium leakage.

　　4.降低運行噪音

　　4. Reduce operating noise

　　當閥門部件之間摩擦過大時，在操作過程中會產(chǎn)生刺耳的噪音。這不僅會對工作環(huán)境造成噪聲污染，影響操作人員的身心健康，還可能是閥門部件出現(xiàn)故障的預警信號。通過定期潤滑，改善部件之間的摩擦狀況，能夠有效降低閥門運行時的噪音，使閥門運行更加平穩(wěn)安靜，同時也便于及時發(fā)現(xiàn)其他潛在的異常情況。

　　When there is excessive friction between valve components, a harsh noise will be produced during operation. This not only causes noise pollution to the working environment and affects the physical and mental health of operators, but may also be a warning signal for valve component failure. By regularly lubricating and improving the friction between components, the noise during valve operation can be effectively reduced, making the valve run more smoothly and quietly, while also facilitating the timely detection of other potential abnormal situations.

　　在對閥門進行潤滑時，應遵循正確的操作流程：

　　When lubricating valves, the correct operating procedures should be followed:

　　首先，清理閥門需要潤滑的部位，使用干凈的抹布或刷子去除表面的灰塵、雜質和舊的潤滑脂，確保潤滑部位清潔。

　　Firstly, clean the parts of the valve that require lubrication by using a clean cloth or brush to remove surface dust, impurities, and old grease, ensuring that the lubrication parts are clean.

　　然后，根據(jù)閥門的結構和潤滑要求，選擇合適的潤滑工具，如油槍、油壺等，將潤滑脂均勻地涂抹或注入到相應的部位。對于閥門的軸承、閥桿螺母等部位，可直接涂抹潤滑脂；對于有注油孔的閥門，通過注油孔將潤滑脂注入到內部的潤滑點。

　　Then, according to the structure and lubrication requirements of the valve, select suitable lubrication tools such as oil guns, oil pots, etc., and evenly apply or inject lubricating grease into the corresponding parts. For the bearings, stem nuts, and other parts of the valve, lubricating grease can be directly applied; For valves with oil injection holes, inject lubricating grease into the internal lubrication points through the oil injection holes.

　　最后，潤滑完成后，檢查閥門的操作情況，確保閥門開關靈活，無異常阻力和噪音。同時，清理多余的潤滑脂，防止其吸附灰塵和雜質，影響閥門的正常運行。

　　Finally, after lubrication is completed, check the operation of the valve to ensure that it opens and closes flexibly, without any abnormal resistance or noise. At the same time, clean excess lubricating grease to prevent it from adsorbing dust and impurities, which may affect the normal operation of the valve.
