Where there is a pipe, there is no place without a valve. The valve is installed on the pipeline to control the flow of fluid medium in the pipeline. It is an important control element. But the valve is also a wearable part. A common valve loss in our life is that the valve is not tightly sealed, resulting in leakage. The leakage at the valve packing is the part of the valve that is prone to leakage failure. Next, Lianggong valve editor will show you why the valve is not tightly sealed?

1、密封辅助结构

1. Sealing auxiliary structure

在温度或密封力的变化下，密封副的结构会发生变化。而这种变化会影响和改变密封副之间的作用力，从而降低阀门密封性能。因此，上阀阀门小编提醒在选择密封件时，一定要选择具有弹性变形的密封件。同时注意密封面的宽度。原因是密封副的接触面不能完全匹配。当密封面的宽度增加时，密封所需的力也会增加。

Under the change of temperature or sealing force, the structure of the sealing pair will change. This change will affect and change the force between the sealing pairs, thereby reducing the sealing performance of the valve. Therefore, the upper valve editor reminds that when choosing seals, we must choose seals with elastic deformation. At the same time, pay attention to the width of the sealing surface. The reason is that the contact surface of the sealing pair cannot match completely. As the width of the sealing surface increases, the force required for sealing also increases.

2、密封面

比压密封面比压影响阀门的密封性能和阀门的使用寿命。因此，上阀阀门小编告诉你密封面的比压也是一个很重要的因素。在同等条件下，比压过高会导致阀门损坏，而比压过低会导致阀门泄漏。因此在设需要充分考虑比压的适当性。

The specific pressure of the sealing surface affects the sealing performance and service life of the valve. Therefore, the specific pressure of the sealing surface is also a very important factor. Under the same conditions, the valve will be damaged if the specific pressure is too high, while the valve will leak if the specific pressure is too low. Therefore, the appropriateness of specific pressure should be fully considered in the design.

3、密封副

密封副的质量主要是指我们必须检查材料的选择、匹配和制造精度。良工阀门小编举例：例如阀瓣与阀座密封面配合良好，可以提高密封性能。周向波纹多的特点是其迷宫密封性能好。

The quality of sealing pair mainly refers to the selection, matching and manufacturing accuracy of materials we must check. For example, the valve clack and the sealing surface of the valve seat are well matched, which can improve the sealing performance. The characteristic of more circumferential ripples is its good labyrinth sealing performance.
