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.

尽管良工截止阀的布局很杂乱紧凑，但运用对比简单省力，在调 理流量和操控节约方面的效果对比抱负。良工截止阀的外形特点是，在阀门的顶部设有手动杆，中 心设有螺纹和套筒式缓冲机。

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.

咱们判定良工截止阀是处于发动仍是闭合状况的首要方法是调查阀杆显露的高度，并依据这个高度来操控阀门的操作。小型的良工截止阀其阀杆和螺纹设置在阀体内，在运用中触摸的传输介质时刻较长，因而简单被腐蚀，而下降密封性，这一点能够经过填充密封料来。

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，在装置良工截止阀时，山东良工阀门提醒大家要事先知道流体的流向，留意保证管路的高出低进，这样装置的意图是减小流体对阀门的压力，从而在启闭阀门时能够节约力气，一起还能够延伸良工截止阀的寿数，在阀门封闭时，阀杆和填料不与流体触摸，减少了腐蚀和走漏的事端发作。

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.

良工截止阀在装置时，需求留意到以下三点：

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

1良工截止阀在装置前应进行密封性查看，保证阀门紧锁时安 全无走漏，填料函无走漏缺点。

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良工截止阀假如手艺无法操作阀杆，可运用F扳手，假如F扳手仍是无法敞开，牢记不要用加长的扳手强行封闭，否则会形成阀门的损坏，导致走漏事端。

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假如良工截止阀是应用在输气管时，在敞开前应进行冷凝水的扫除，这样是为了防止由于温度和压力的俄然增 大导致的密封件的损坏，提前对管道预热，在断定状况后可将压力调整到所需水平。

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.
