沪工阀门在开关过程中，阀瓣在过程中会摩擦和挤伤密封面，使密封表面产生磨损。沪工阀门的两密封面之间，在高温高压的情况下容易发生原子相互渗透渗出的情况，很容易导致密封面粘连。两密封面移动时，黏连处很容易发生撕拉，导致损坏。

During the opening and closing process of Shanghai Industrial Valve, the valve disc will rub and squeeze the sealing surface, causing wear on the sealing surface. Under high temperature and pressure conditions, the two sealing surfaces of Shanghai industrial valves are prone to atomic permeation and leakage, which can easily lead to adhesion of the sealing surfaces. When the two sealing surfaces move, the adhesive joint is prone to tearing and damage.

在一定速度下介质回冲撞密封面，一些浮游细粒侵犯犯密封面，尤其高速活动的介质冲洗密封面，介质混流和局部汽化时，产气愤泡爆破冲击密封面表面，使其造成局部损坏。下面为大家介绍沪工阀门密封面损坏的主要原因。

At a certain speed, the medium collides with the sealing surface, and some floating fine particles invade and invade the sealing surface. Especially when the medium moves at high speed, it flushes the sealing surface. When the medium mixes and vaporizes locally, it produces bubbles that explode and impact the sealing surface, causing local damage. Below we will introduce the main reasons for the damage of the sealing surface of Shanghai Industrial Valve.

在密封面互相接触时，密封面与封闭体和阀体的接触以及介质的浓度差等原因，很容易发生电化学侵蚀，致使密封面受损。主要是沪工阀门选型不正确，导致压力过大以及封闭过快，使密封面受到冲蚀和磨损。

When the sealing surfaces come into contact with each other, electrochemical corrosion can easily occur due to the contact between the sealing surface, the sealing body, and the valve body, as well as the concentration difference of the medium, resulting in damage to the sealing surface. The main reason is the incorrect selection of valves by Hugong, which leads to excessive pressure and rapid sealing, causing erosion and wear on the sealing surface.

员工在操作过程中，不正确的操作很容易导致密封面损坏。购买的密封面质量不合格。主要表现在购买的密封面上有裂纹、气孔和夹碴等缺陷，这种密封面材质不匀、不耐侵蚀，当然，这里面也存在设计的原因，了解沪工阀门的业内人士都了解一点，沪工阀门广泛应用在石油化工等行业中，特别对于石油的集输系统来说，应用更为广泛。

Incorrect operation by employees during the operation process can easily lead to damage to the sealing surface. The purchased sealing surface is of poor quality. This is mainly manifested in defects such as cracks, pores, and slag inclusions on the purchased sealing surface. The material of this sealing surface is uneven and not resistant to corrosion. Of course, there are also design reasons for this. Industry insiders who understand Hugong valves know one thing. Hugong valves are widely used in industries such as petrochemicals, especially in petroleum gathering and transportation systems, where they are more widely used.

如今，油田进入高含水开发期，对沪工阀门的腐蚀也日益严重，因此如何处理沪工阀门的渗漏问题也十分重要。将沪工阀门的密封方式改为油封、填料密封等多种方式相结合。在安装过程中，在填料函留出一定的空间，可以在油封下部分和剩余填料之间加入一个压缩弹簧，有效减少泄漏。可以在压盖与填料函之间放一石棉垫子，通过填料压盖的螺栓使得压盖与填料函的表面紧密贴合。在生产中可以有效避免渗漏现象，有效避免了原油污染的发生。

Nowadays, oil fields have entered a period of high water content development, and the corrosion of Hugong valves is becoming increasingly severe. Therefore, it is also very important to deal with the leakage problem of Hugong valves. Change the sealing method of Hugong valves to a combination of oil seals, packing seals, and other methods. During installation, leave some space in the packing box and add a compression spring between the lower part of the oil seal and the remaining packing to effectively reduce leakage. An asbestos pad can be placed between the gland and the packing box, and the surface of the gland and packing box can be tightly adhered by the bolts of the packing gland. In production, leakage can be effectively avoided, effectively avoiding the occurrence of crude oil pollution.
