良工閥門:閥門標識有什么作用?

來源:http://www.szgotta.com.cn/ 日期:2024-05-22 發布人:創始人

 閥門的識別對在缺少閥門圖紙資料,丟失了銘牌和閥門零件不齊全的情況下,正確地使用閥門,焊補閥件,修復閥件和更換閥件具有重要意義。現將閥門的標識、材質鑒別和閥門的識別分述如下:

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“閥門的站礎知識”中學到知識,根據閥門上的銘牌和標志以及閥門上的涂漆顏色.就可以直接識別閥門的類別、結構形式、材料、公稱通徑、公稱壓力(或工作壓力)、適應介質、溫度及關閉方向等。

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.銘牌固定在閥體或手輪上。銘牌的數據比較全,反映了閥門基本特性。根據銘牌上的生產廠,向生井廠索取該閥易損怦圖紙和資料,根據出廠日期參考修理的內容。根據銘牌上提供的使用條件,確定更換墊片、盤根的材料和形式以及確定更換其他閥件的材料

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.標志是用鑄造,打印等方法在閥體上標示閥門公稱壓力、工作壓力、公稱口徑和介質流向的。

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.

  閥門上還有一種標志——開度指示器,它有開啟的標尺刻度線或表示開閉的箭頭等。節流閥、暗桿閘閥上端安裝有開度指示器,在手輪上標有箭頭指向表示關閉方向。在閥桿端面部位上刻有直線溝槽口與閥門通道一致表示開啟,溝槽與通道成90°時為關閉。

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.閥門上涂有各種油漆,不光是為了防銹好看。而是為了便于識別閥門的材料。表示閥體材料的涂漆。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.

  為了從閥門的外觀看出它的結構、材質和基本特性,要求在閥體上鑄造、打印或安上銘牌,表明閥門型號、公稱直徑、介質流向及廠名,并在閥體、手輪及法蘭外緣上按規定刷不同顏色的漆。

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.
