滬工閥門在開關過程中，閥瓣在過程中會摩擦和擠傷密封面，使密封表面產生磨損。滬工閥門的兩密封面之間，在高溫高壓的情況下容易發生原子相互滲透滲出的情況，很容易導致密封面粘連。兩密封面移動時，黏連處很容易發生撕拉，導致損壞。

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.

在一定速度下介質回沖撞密封面，一些浮游細粒侵犯犯密封面，尤其高速活動的介質沖洗密封面，介質混流和局部汽化時，產氣憤泡爆破沖擊密封面表面，使其造成局部損壞。下面為大家介紹滬工閥門密封面損壞的主要原因。

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.

在密封面互相接觸時，密封面與封閉體和閥體的接觸以及介質的濃度差等原因，很容易發生電化學侵蝕，致使密封面受損。主要是滬工閥門選型不正確，導致壓力過大以及封閉過快，使密封面受到沖蝕和磨損。

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.

員工在操作過程中，不正確的操作很容易導致密封面損壞。購買的密封面質量不合格。主要表現在購買的密封面上有裂紋、氣孔和夾碴等缺陷，這種密封面材質不勻、不耐侵蝕，當然，這里面也存在設計的原因，了解滬工閥門的業內人士都了解一點，滬工閥門廣泛應用在石油化工等行業中，特別對于石油的集輸系統來說，應用更為廣泛。

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，油田進入高含水開發期，對滬工閥門的腐蝕也日益嚴重，因此如何處理滬工閥門的滲漏問題也十分重要。將滬工閥門的密封方式改為油封、填料密封等多種方式相結合。在安裝過程中，在填料函留出一定的空間，可以在油封下部分和剩余填料之間加入一個壓縮彈簧，有效減少泄漏。可以在壓蓋與填料函之間放一石棉墊子，通過填料壓蓋的螺栓使得壓蓋與填料函的表面緊密貼合。在生產中可以有效避免滲漏現象，有效避免了原油污染的發生。

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.
