一、型號與規格核對問題?

1、 Model and specification verification issues

在閥門安裝項目中，常出現安裝人員未仔細核對閥門型號、規格便匆忙安裝，導致安裝后閥門無法滿足系統運行需求，如流量、壓力控制等方面出現偏差，嚴重時需拆除重新安裝，造成時間和成本浪費。部分安裝人員認為設計圖紙上標注清晰，無需再次核對，且核對過程繁瑣，存在僥幸心理。而另一部分嚴謹的人員則堅持必須核對。?

In valve installation projects, it is common for installation personnel to hastily install valves without carefully checking the valve model and specifications, resulting in the valves being unable to meet the system's operational requirements after installation, such as deviations in flow and pressure control. In severe cases, they may need to be removed and reinstalled, causing time and cost waste. Some installation personnel believe that the markings on the design drawings are clear and do not need to be checked again, and the verification process is cumbersome, with a mentality of taking chances. And another group of rigorous personnel insist on checking. ?

良工閥門建議，在閥門安裝之前，務必仔細核對所用閥門的型號、規格是否與設計相符。這一步驟雖看似簡單，但至關重要。可建立雙人復核制度，安裝人員完成初次核對后，由技術負責人再次確認，確保無誤，從源頭避免因型號、規格錯誤引發的安裝問題。?

Lianggong Valve suggests that before installing the valve, it is necessary to carefully check whether the model and specifications of the valve used are consistent with the design. This step may seem simple, but it is crucial. A dual person review system can be established. After the installation personnel complete the initial verification, the technical leader will confirm again to ensure accuracy and avoid installation problems caused by model and specification errors from the source. ?

二、適用性檢查爭議?

2、 Applicability check dispute

對于閥門是否能在要求條件下應用，安裝團隊內部常存在爭議。一些人覺得閥門只要外觀無損壞，能正常安裝即可，忽視了其在特定條件下的適用性，如溫度、壓力、介質腐蝕性等。而經驗豐富的人員深知，若閥門不適用，運行中可能出現泄漏、損壞等嚴重問題。?

There is often controversy within the installation team regarding whether the valve can be applied under the required conditions. Some people think that as long as the appearance of the valve is undamaged and can be installed normally, they ignore its applicability under specific conditions such as temperature, pressure, and corrosiveness of the medium. Experienced personnel are well aware that if the valve is not suitable, serious problems such as leakage and damage may occur during operation. ?

根據閥門的型號和出廠說明書，全面檢查對照該閥門可否在要求的條件下應用。良工閥門在每臺閥門出廠時均配備詳細說明書，明確標注適用范圍。安裝團隊應組織專項培訓，讓每位成員了解如何依據說明書判斷閥門適用性，同時可邀請良工閥門技術專家進行現場指導，提高安裝人員對閥門適用性判斷的準確性。?

According to the valve model and factory manual, conduct a comprehensive inspection to compare whether the valve can be used under the required conditions. Lianggong Valve is equipped with detailed instructions for each valve at the factory, clearly indicating the scope of application. The installation team should organize specialized training to enable each member to understand how to judge valve applicability based on the instruction manual. At the same time, skilled valve technicians can be invited to provide on-site guidance to improve the accuracy of valve applicability judgment by installation personnel. ?

三、閥門吊裝方式問題?

3、 Valve lifting method issue

閥門吊裝過程中，因吊裝方式不當導致閥桿與手輪損壞的情況時有發生。部分施工人員為圖方便，將繩索拴在手輪或閥桿上進行吊裝，認為這樣操作簡單快捷。然而，這種做法極易使閥桿與手輪承受過大拉力，造成變形或損壞。?

During the valve lifting process, it is common for the valve stem and handwheel to be damaged due to improper lifting methods. Some construction workers, for the sake of convenience, tie ropes to handwheels or valve stems for lifting, believing that this operation is simple and fast. However, this approach can easily cause excessive tension on the valve stem and handwheel, resulting in deformation or damage. ?

良工閥門強調，閥門吊裝時，繩索應綁在閥體與閥蓋的法蘭連接處。可制作專門的吊裝夾具，適配不同規格閥門的法蘭，確保繩索穩固連接，避免與手輪、閥桿接觸。同時，對吊裝人員進行專業培訓，考核合格后方可參與閥門吊裝作業，規范吊裝操作流程。?

Lianggong Valve emphasizes that when lifting the valve, the rope should be tied to the flange connection between the valve body and the valve cover. Special lifting fixtures can be made to adapt to flanges of different specifications of valves, ensuring stable connection of ropes and avoiding contact with handwheels and valve stems. At the same time, professional training should be provided to the lifting personnel, who can only participate in valve lifting operations after passing the assessment, and the lifting operation process should be standardized.

四、水平管道上閥門安裝方向爭議?

4、 Controversy over the installation direction of valves on horizontal pipelines

在水平管道上安裝閥門時，閥桿的安裝方向存在爭議。部分人員認為閥桿安裝方向對閥門使用影響不大，選擇向下安裝以節省空間。但實際上，閥桿向下安裝不利于操作與維護，且容易積聚雜質，加速閥桿腐蝕。?

There is controversy over the installation direction of the valve stem when installing valves on horizontal pipelines. Some personnel believe that the installation direction of the valve stem has little impact on the use of the valve, and choose to install it downwards to save space. However, in reality, installing the valve stem downwards is not conducive to operation and maintenance, and it is easy to accumulate impurities, accelerating valve stem corrosion. ?

良工閥門明確要求，在水平管道上安裝閥門時，閥桿應垂直向上。在施工圖紙設計階段，就應明確標注閥門安裝方向，安裝人員嚴格按照圖紙施工。對于空間有限的特殊情況，可采用特殊設計的閥門，如加長閥桿或采用直角傳動裝置，確保閥桿處于便于操作和維護的位置。?

Lianggong Valve explicitly requires that when installing valves on horizontal pipelines, the valve stem should be vertically upward. During the construction drawing design phase, the installation direction of valves should be clearly marked, and installation personnel should strictly follow the drawings for construction. For special situations with limited space, specially designed valves can be used, such as elongated valve stems or right angle transmission devices, to ensure that the valve stem is in a position that is easy to operate and maintain. ?

五、連接方式問題?

5、 Connection method issue

安裝閥門時，強行對口連接的情況屢禁不止。一些施工團隊為趕工期，在管道與閥門接口存在偏差時，采用生拉硬拽的方式強行連接。這種做法會使閥門內部部件受力不均，導致密封損壞、閥門變形等問題，嚴重影響閥門使用壽命和系統運行安全。?

When installing valves, the situation of forcibly connecting them is repeatedly prohibited. Some construction teams, in order to meet the deadline, forcibly connect pipelines and valve interfaces by pulling and pulling them. This approach can cause uneven stress on the internal components of the valve, leading to seal damage, valve deformation, and other issues, seriously affecting the service life of the valve and the safety of system operation. ?

安裝閥門時，嚴禁采用生拉硬拽的強行對口連接方式。在安裝前，仔細測量管道與閥門接口尺寸，確保誤差在允許范圍內。若出現偏差，應采用合適的調整工具和方法進行修正，如使用管道調整器、重新切割打磨管口等。同時，加強施工過程監督，對違規操作及時制止并予以處罰。?

When installing valves, it is strictly prohibited to use forced connection methods such as pulling and pulling. Before installation, carefully measure the size of the pipeline and valve interface to ensure that the error is within the allowable range. If there is a deviation, appropriate adjustment tools and methods should be used for correction, such as using pipeline adjusters, re cutting and polishing pipe openings, etc. At the same time, strengthen the supervision of the construction process, promptly stop and punish illegal operations. ?

六、明桿閘閥安裝環境爭議?

6、 Environmental controversy surrounding the installation of Minggan gate valves

對于明桿閘閥的安裝環境，部分人員認為即使安裝在地下潮濕處，只要做好防腐措施即可。但實際情況是，地下潮濕環境復雜，普通防腐措施難以完全阻止閥桿銹蝕，一旦閥桿銹蝕，會影響閥門的正常開啟和關閉。?

For the installation environment of the rising stem gate valve, some personnel believe that even if it is installed underground in a damp place, as long as anti-corrosion measures are taken, it is sufficient. But in reality, the underground humid environment is complex, and ordinary anti-corrosion measures are difficult to completely prevent valve stem corrosion. Once the valve stem is corroded, it will affect the normal opening and closing of the valve. ?

良工閥門建議，明桿閘閥不宜裝在地下潮濕處。若因工程特殊需要必須安裝在潮濕環境，應選用特殊材質（如不銹鋼材質）的明桿閘閥，并設置專門的防潮、排水設施，定期對閥桿進行保養維護，涂抹防銹油脂，檢查銹蝕情況，確保閥門正常運行。

Lianggong Valve suggests that rising stem gate valves should not be installed in damp underground locations. If it is necessary to install in a humid environment due to special engineering requirements, a rising stem gate valve made of special materials (such as stainless steel) should be selected, and specialized moisture-proof and drainage facilities should be set up. The valve stem should be regularly maintained, rust proof grease should be applied, and rust should be checked to ensure the normal operation of the valve.
