良工阀门:阀门标识有什么作用?

来源: //www.rabieb.com/日期:2024-05-22 发布人:创始人

 阀门的识别对在缺少阀门图纸资料,丢失了铭牌和阀门零件不齐全的情况下,正确地使用阀门,焊补阀件,修复阀件和更换阀件具有重要意义。现将阀门的标识、材质鉴别和阀门的识別分述如下:

The identification of valves is of great significance for the correct use of valves, welding repair of valve components, repairing and replacing valve components in the absence of valve drawings, loss of nameplates, and incomplete valve components. The identification, material identification, and valve identification of valves are described as follows:

  利用“阀门的站础知识”中学到知识,根据阀门上的铭牌和标志以及阀门上的涂漆颜色.就可以直接识别阀门的类别、结构形式、材料、公称通径、公称压力(或工作压力)、适应介质、温度及关闭方向等。

By utilizing the basic knowledge of valves, one can directly identify the type, structural form, material, nominal diameter, nominal pressure (or working pressure), suitable medium, temperature, and closing direction of the valve based on the nameplate and logo on the valve, as well as the paint color on the valve.

  1.铭牌固定在阀体或手轮上。铭牌的数据比较全,反映了阀门基本特性。根据铭牌上的生产厂,向生井厂索取该阀易损怦图纸和资料,根据出厂日期参考修理的内容。根据铭牌上提供的使用条件,确定更换垫片、盘根的材料和形式以及确定更换其他阀件的材料

1. The nameplate is fixed on the valve body or handwheel. The data on the nameplate is quite comprehensive, reflecting the basic characteristics of the valve. According to the manufacturer on the nameplate, request the vulnerable valve diagram and information from Shengjing Factory, and refer to the repair content based on the factory date. Based on the usage conditions provided on the nameplate, determine the materials and forms for replacing gaskets and packing, as well as the materials for replacing other valve components

  2.标志是用铸造,打印等方法在阀体上标示阀门公称压力、工作压力、公称口径和介质流向的。

2. The mark is used to indicate the nominal pressure, working pressure, nominal diameter, and medium flow direction of the valve on the valve body through casting, printing, and other methods.

  阀门上还有一种标志——开度指示器,它有开启的标尺刻度线或表示开闭的箭头等。节流阀、暗杆闸阀上端安装有开度指示器,在手轮上标有箭头指向表示关闭方向。在阀杆端面部位上刻有直线沟槽口与阀门通道一致表示开启,沟槽与通道成90°时为关闭。

There is also a sign on the valve - an opening indicator, which has an open scale line or an arrow indicating the opening and closing. The upper end of the throttle valve and non rising stem gate valve is equipped with an opening indicator, and an arrow is marked on the handwheel to indicate the direction of closure. A straight groove is engraved on the end face of the valve stem, which is consistent with the valve channel to indicate opening. When the groove is at a 90 ° angle with the channel, it is considered closed.

  3.阀门上涂有各种油漆,不光是为了防锈好看。而是为了便于识別阀门的材料。表示阀体材料的涂漆。表示密封面材料的涂漆。

3. The valve is coated with various paints, not only for rust prevention and aesthetics. But for the convenience of identifying the material of the valve. Indicates the painting of the valve body material. Indicates the painting of the sealing surface material.

  为了从阀门的外观看出它的结构、材质和基本特性,要求在阀体上铸造、打印或安上铭牌,表明阀门型号、公称直径、介质流向及厂名,并在阀体、手轮及法兰外缘上按规定刷不同颜色的漆。

In order to see the structure, material, and basic characteristics of the valve from its appearance, it is required to cast, print, or install a nameplate on the valve body, indicating the valve model, nominal diameter, medium flow direction, and factory name. Different colors of paint should be painted on the valve body, handwheel, and flange outer edges according to regulations.
