Shanghai Lianggong valve Shandong sales center will introduce the problems needing attention in the installation of Lianggong stop valve! Lianggong stop valve is mainly used in the chemical industry. In practical application, it is mainly used for the control of water, steam and compressed air. Because it is opened and closed by the lifting of the stem strand head, it is not suitable for data with high viscosity of particles.

盡管良工截止閥的布局很雜亂緊湊，但運用對比簡單省力，在調 理流量和操控節約方面的效果對比抱負。良工截止閥的外形特點是，在閥門的頂部設有手動桿，中 心設有螺紋和套筒式緩沖機。

Although the layout of Lianggong stop valve is very messy and compact, its application is relatively simple and labor-saving, and its effect in regulating flow and saving operation is relatively ambitious. The appearance feature of Lianggong stop valve is that a manual rod is set at the top of the valve, and a thread and sleeve buffer are set in the center.

咱們判定良工截止閥是處于發動仍是閉合狀況的首要方法是調查閥桿顯露的高度，并依據這個高度來操控閥門的操作。小型的良工截止閥其閥桿和螺紋設置在閥體內，在運用中觸摸的傳輸介質時刻較長，因而簡單被腐蝕，而下降密封性，這一點能夠經過填充密封料來解決。

The first way to determine whether the Lianggong stop valve is in the start or closed state is to investigate the exposed height of the valve stem and operate the valve according to this height. The valve stem and thread of the small-sized good worker stop valve are arranged in the valve body. The transmission medium touched during operation is long, so it is easy to be corroded and reduce the tightness. This can be solved by filling sealing material.

所以，在裝置良工截止閥時，山東良工閥門提醒大家要事先知道流體的流向，留意保證管路的高出低進，這樣裝置的意圖是減小流體對閥門的壓力，從而在啟閉閥門時能夠節約力氣，一起還能夠延伸良工截止閥的壽數，在閥門封閉時，閥桿和填料不與流體觸摸，減少了腐蝕和走漏的事端發作。

Therefore, when installing the Lianggong stop valve, Shandong Lianggong valve reminds everyone to know the flow direction of the fluid in advance and pay attention to ensuring that the pipeline is higher than lower. The purpose of this device is to reduce the pressure of the fluid on the valve, so as to save energy when opening and closing the valve and extend the service life of the Lianggong stop valve. When the valve is closed, the valve stem and packing do not touch the fluid, Reduce the occurrence of corrosion and leakage.

良工截止閥在裝置時，需求留意到以下三點：

When the Lianggong stop valve is installed, the following three points should be noted:

1良工截止閥在裝置前應進行密封性查看，保證閥門緊鎖時安 全無走漏，填料函無走漏缺點。

1. The sealing performance of the well-trained stop valve shall be checked before the device to ensure that the valve is safe without leakage when locked, and the stuffing box is free of leakage.

2良工截止閥假如手藝無法操作閥桿，可運用F扳手，假如F扳手仍是無法敞開，牢記不要用加長的扳手強行封閉，否則會形成閥門的損壞，導致走漏事端。

2. If the valve stem of Lianggong stop valve cannot be operated by technology, f wrench can be used. If f wrench still cannot be opened, remember not to forcibly close it with an extended wrench, otherwise it will cause damage to the valve and lead to leakage.

3假如良工截止閥是應用在輸氣管時，在敞開前應進行冷凝水的掃除，這樣是為了防止由于溫度和壓力的俄然增 大導致的密封件的損壞，提前對管道預熱，在斷定狀況后可將壓力調整到所需水平。

3 if the good worker stop valve is applied to the gas transmission pipe, the condensate shall be cleaned before opening, so as to prevent the damage of the seal caused by the sudden increase of temperature and pressure, preheat the pipeline in advance, and adjust the pressure to the required level after determining the condition.
