球閥的標準|球閥的作用

球閥的標準|球閥的作用

一、總結球閥標準的重要性

球閥是日常生活和各種工況運用最多的閥門之一，球閥體積小，質量輕，安裝方便，力矩小，開個省力，相對于其他同口徑閥門，價格實惠！

但是球閥種類繁多，品種多樣，客戶在選型的時候，往往不知道如何選擇，總覺得大同小異，差距不大，這個也行，那個也像。其實這是閥門選擇的一種誤區。

雖然球閥品種多樣，種類繁多，但是每一個球閥在設計的時候，都是有對應的工況條件和執行標準，所以要對癥下藥，方可做到選擇恰當，經濟實惠.

信茂技術部根據多年的工作經驗在這里總結了球閥的標準和作用。

三、球閥的作用

球閥對于我們來說并不陌生，是一種由旋塞轉變而來的，這種球閥不是通過長方體開關進行啟閉的，主要是通過球體的開關而進行工作的，一般的球體上都有一個閥桿，這個閥桿的旋動決定了球體的旋動，這樣正好有利于球體的切斷和分配，對于生產有很大的幫助，球閥開口的大小還具有控制流量的作用，這個對于三通球閥來說是一個很好的功能。球閥啟閉迅速，密封性好，結構簡單，低流阻，廣泛使用于現代工業場合。球閥根據結構形式可以分為固定式球閥、三通球閥、四通球閥等;根據連接方式，分為法蘭球閥、對夾球閥、內螺紋球閥、外螺紋球閥、焊接球閥、卡箍球閥(一般是衛生級球閥)、卡套式球閥等;按密封材料則可分為軟密封球閥和金屬硬密封球閥。軟密封球閥一般適用于溫度小于150度左右的介質，150度以上的介質，則選用PPL密封或者金屬密封。
