在注脂閥門中，往往忽視注脂的問題。注射油槍加油后，操作者選用了油管及油管連接方式，進行注脂作業。主要有兩種情況：一是注脂量少，注脂不足，密封面由于缺少潤滑劑而加速磨損。相反，過量的注脂，造成浪費。就是不能根據閥門類型分類，對不同閥門密封容量進行精確計算。可根據閥門大小及種類計算密封容量，再合理地注入適量潤滑脂。

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、注脂時，常常忽略壓力問題。注脂作業時，注脂壓力呈規律的峰谷變化。壓差、密封漏或失效、壓力過高、注油口堵塞、油封硬化、密封球閥球、閥板卡死等。當注脂壓力過低時，注入的潤滑脂多流入閥腔底部，一般發生在小型閘閥上。如果注脂壓力過高，一方面要檢查注脂器是否存在脂孔阻塞的情況要更換；另一方面是脂類硬化，要用清洗液反復軟化已經失效的密封脂，然后注入新的潤滑脂。另外，密封方式和密封材料，也會影響注脂壓力，不同的密封形式有不同的注脂壓力，一般情況下硬密封注脂壓力要高于軟密封。

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、注脂閥時，要注意閥門在開關位置的問題。球閥在維護和保養時一般是在開啟狀態，特殊情況下選擇關機維修。其它閥門（不銹鋼閥門）也不能完全用開位論處。在維修過程中，閘閥必須處于關閉狀態，確保潤滑脂沿密封圈充滿密封槽，如果打開，密封脂就直接掉入流道或閥腔，造成浪費。

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、注脂時，經常忽略注脂的效果問題。脂肪注射操作時壓力、注射脂肪、開關位置均正常。但是為了保證注脂效果，有時需要打開或關閉閥門，檢查潤滑效果，確認閥門閥球或閘板表面是否均勻潤滑。

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.

注脂時，要注意閥體排污和絲塞泄壓問題。氣門加壓試驗后，密封腔內氣和水汽會因環境溫度升高而上升，因此在注脂過程中要先放油泄壓，才能順利地進行。注脂后密封腔中的空氣和水份被完全排出。及時排除閥腔壓力，也保證了閥門的使用安全。在注油結束后，一定要擰緊排污及減壓閥堵，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.

注脂的時候，一定要注意不能出現油脂不均勻的情況。通常情況下，從靠近注脂口的出脂孔先出脂，然后到低點，后為高點，逐次排脂。如未按規定或不排脂證明有堵塞，應及時清通。

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、注脂時還應注意閥門的通徑與密封圈的座平齊問題。如球閥，如有開位過盈，可向內調整開位限位器，確認平直通徑后鎖定。調節限制不可只追求開啟或關閉位置，要綜合考慮。若開位平齊，關不到位，會造成閥門關閉不嚴。同理，調整關到位，也要考慮相應的開度調整。保證閥門的直角行程。

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。防止雜質進入，或脂質在油脂表面氧化，封蓋上要涂防銹脂，避免生銹。供下次操作時應用。

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、注脂時，也要考慮以后分油順序輸送具體問題。考慮到柴油質量的差異，應考慮汽油的洗脫和分解能力。稍后閥門操作，遇上汽油段作業，及時補充潤滑脂，防止出現磨損情況。

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.

注脂時，不要忽略在閥桿部位的注脂。氣門軸套處有滑動軸套或填料，還需保持潤滑狀態，以減少運行中的摩擦阻力，如不能保證潤滑，則電動操作扭矩加大磨損部件，手動操作開關費力。

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.

有些球閥閥體上標有箭頭，如無英文FIOW字，則為密封座作用方向，不作為介質流向參考，閥門自泄方向相反。雙密封球閥一般為雙向流動型。

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.
