在注脂阀门中，往往忽视注脂的问题。注射油枪加油后，操作者选用了油管及油管连接方式，进行注脂作业。主要有两种情况：一是注脂量少，注脂不足，密封面由于缺少润滑剂而加速磨损。相反，过量的注脂，造成浪费。就是不能根据阀门类型分类，对不同阀门密封容量进行精确计算。可根据阀门大小及种类计算密封容量，再合理地注入适量润滑脂。

In grease valves, the issue of grease injection is often overlooked. After refueling with the injection gun, the operator selected the oil pipe and its connection method for the grease injection operation. There are mainly two situations: one is insufficient grease injection, and the sealing surface accelerates wear due to the lack of lubricant. On the contrary, excessive fat injection causes waste. It is impossible to accurately calculate the sealing capacity of different valves based on valve type classification. The sealing capacity can be calculated based on the size and type of valve, and an appropriate amount of lubricating grease can be injected reasonably.

二、注脂时，常常忽略压力问题。注脂作业时，注脂压力呈规律的峰谷变化。压差、密封漏或失效、压力过高、注油口堵塞、油封硬化、密封球阀球、阀板卡死等。当注脂压力过低时，注入的润滑脂多流入阀腔底部，一般发生在小型闸阀上。如果注脂压力过高，一方面要检查注脂器是否存在脂孔阻塞的情况要更换；另一方面是脂类硬化，要用清洗液反复软化已经失效的密封脂，然后注入新的润滑脂。另外，密封方式和密封材料，也会影响注脂压力，不同的密封形式有不同的注脂压力，一般情况下硬密封注脂压力要高于软密封。

2、 When injecting fat, pressure issues are often overlooked. During liposuction, the liposuction pressure exhibits a regular peak valley variation. Differential pressure, seal leakage or failure, high pressure, blocked oil injection port, oil seal hardening, sealed ball valve ball, valve plate jamming, etc. When the grease injection pressure is too low, the injected lubricating grease mostly flows into the bottom of the valve chamber, usually occurring on small gate valves. If the grease injection pressure is too high, on the one hand, it is necessary to check if there is any blockage in the grease hole of the grease injector and replace it; On the other hand, lipid hardening requires repeatedly softening the expired sealing grease with cleaning solution, and then injecting new lubricating grease. In addition, the sealing method and sealing material can also affect the grease injection pressure. Different sealing forms have different grease injection pressures, and in general, the grease injection pressure for hard seals is higher than that for soft seals.

三、注脂阀时，要注意阀门在开关位置的问题。球阀在维护和保养时一般是在开启状态，特殊情况下选择关机维修。其它阀门（不锈钢阀门）也不能完全用开位论处。在维修过程中，闸阀必须处于关闭状态，确保润滑脂沿密封圈充满密封槽，如果打开，密封脂就直接掉入流道或阀腔，造成浪费。

3、 When filling the grease valve, pay attention to the issue of the valve being in the on/off position. Ball valves are generally in the open state during maintenance and upkeep, and in special circumstances, they can be shut down for repair. Other valves (stainless steel valves) cannot be fully opened. During the maintenance process, the gate valve must be in a closed state to ensure that the lubricating grease fills the sealing groove along the sealing ring. If opened, the sealing grease will directly fall into the flow channel or valve chamber, causing waste.

四、注脂时，经常忽略注脂的效果问题。脂肪注射操作时压力、注射脂肪、开关位置均正常。但是为了保证注脂效果，有时需要打开或关闭阀门，检查润滑效果，确认阀门阀球或闸板表面是否均匀润滑。

4、 When injecting fat, the effectiveness of the injection is often overlooked. The pressure, injection fat, and switch position are all normal during the fat injection operation. However, in order to ensure the lubrication effect, sometimes it is necessary to open or close the valve, check the lubrication effect, and confirm whether the surface of the valve ball or gate is evenly lubricated.

注脂时，要注意阀体排污和丝塞泄压问题。气门加压试验后，密封腔内气和水汽会因环境温度升高而上升，因此在注脂过程中要先放油泄压，才能顺利地进行。注脂后密封腔中的空气和水份被完全排出。及时排除阀腔压力，也保证了阀门的使用。在注油结束后，一定要拧紧排污及减压阀堵，以防意外。

When injecting grease, attention should be paid to valve body drainage and plug pressure relief issues. After the valve pressurization test, the air and water vapor in the sealing chamber will rise due to the increase in ambient temperature. Therefore, during the grease injection process, oil should be drained and pressure released first in order to proceed smoothly. After grease injection, the air and water in the sealed chamber are completely discharged. Timely elimination of valve chamber pressure also ensures the safety of valve use. After the oil injection is completed, be sure to tighten the drain and pressure reducing valve plugs to prevent accidents.

注脂的时候，一定要注意不能出现油脂不均匀的情况。通常情况下，从靠近注脂口的出脂孔先出脂，然后到低点，后为高点，逐次排脂。如未按规定或不排脂证明有堵塞，应及时清通。

When injecting grease, it is important to be careful not to have uneven grease distribution. Normally, the fat is discharged first from the grease outlet near the grease injection port, then to the low point, and then to the high point, sequentially. If there is blockage due to failure to follow regulations or failure to drain fat, it should be cleared in a timely manner.

第7、注脂时还应注意阀门的通径与密封圈的座平齐问题。如球阀，如有开位过盈，可向内调整开位限位器，确认平直通径后锁定。调节限制不可只追求开启或关闭位置，要综合考虑。若开位平齐，关不到位，会造成阀门关闭不严。同理，调整关到位，也要考虑相应的开度调整。保证阀门的直角行程。

When injecting grease, attention should also be paid to the alignment between the valve diameter and the seat of the sealing ring. For ball valves, if there is interference in the opening position, the opening limiter can be adjusted inward to confirm the straight diameter and then locked. Adjusting restrictions should not only focus on the open or closed position, but should be considered comprehensively. If the opening position is flush and cannot be closed properly, it will cause the valve to not close tightly. Similarly, when adjusting the closing position, corresponding opening adjustments should also be considered. Ensure the right angle stroke of the valve.

八、注脂后，一定要封好注脂口。防止杂质进入，或脂质在油脂表面氧化，封盖上要涂防锈脂，避免生锈。供下次操作时应用。

8、 After liposuction, be sure to seal the liposuction port properly. To prevent impurities from entering or lipids from oxidizing on the surface of the oil, anti rust grease should be applied on the cover to avoid rusting. For application in the next operation.

九、注脂时，也要考虑以后分油顺序输送具体问题。考虑到柴油质量的差异，应考虑汽油的洗脱和分解能力。稍后阀门操作，遇上汽油段作业，及时补充润滑脂，防止出现磨损情况。

9、 When injecting grease, it is also necessary to consider the specific issue of oil separation sequence transportation in the future. Considering the differences in diesel quality, the elution and decomposition capabilities of gasoline should be taken into account. Operate the valve later, and in case of gasoline section operation, replenish lubricating grease in a timely manner to prevent wear and tear.

注脂时，不要忽略在阀杆部位的注脂。气门轴套处有滑动轴套或填料，还需保持润滑状态，以减少运行中的摩擦阻力，如不能保证润滑，则电动操作扭矩加大磨损部件，手动操作开关费力。

When applying grease, do not ignore the application of grease on the valve stem. There is a sliding shaft sleeve or packing at the valve shaft sleeve, and it is necessary to maintain lubrication to reduce friction resistance during operation. If lubrication cannot be guaranteed, the electric operation torque will increase the wear of the parts, and manual operation of the switch will be laborious.

有些球阀阀体上标有箭头，如无英文FIOW字，则为密封座作用方向，不作为介质流向参考，阀门自泄方向相反。双密封球阀一般为双向流动型。

Some ball valves are marked with arrows on the valve body. If there is no English word "FIOW", it indicates the direction of the sealing seat and is not used as a reference for the flow direction of the medium. The direction of the valve's self leakage is opposite. Double sealed ball valves are generally bi-directional flow type.
