Selection principle of globe valve
2011-11-1 16:08:25

    截止阀 选用也有许多的技巧;下面我们就一起谈谈 截止阀的 选用原则: As everyone knows, there are also many skills in the selection of globe valves ; let's talk about the principles of globe valve selection:

   选用截止阀共有五个原则: There are five principles for selecting the stop valve :

要求 节精度不高 ,且对 管路直径 比较小的;有两种供应选择: 流量调节 压力调节 1. If the selection requires low accuracy of the joint and the diameter of the pipeline is relatively small; there are two supply options: flow adjustment ; pressure adjustment .

截止、平衡阀或 柱塞阀 ,一般都使用在 城市建设的供水、供热工程上 公称通经较小的管路 2. Normally, cut-off, balance valve or plunger valve is generally used for water supply and heat supply projects in urban construction ; nominally through smaller pipes .

a . 针阀 b . 取样阀 c . 压力计阀 d . 仪表 3. If used on small valves, there are four supply options: a . Needle valve ; b . Sampling valve ; c . Pressure gauge valve ; d . Instrument valve .

公称压力32MPa 公称压力16MPa 公称压力PN160 或者 PN320 的高压角式截止阀或 高压角式节流阀 ;都用在 合成工业 ,生产一些 小化肥和大化肥 4. High pressure angle globe valves or high pressure angle throttle valves such as nominal pressure 32MPa , nominal pressure 16MPa , nominal pressure PN160 or PN320 ; both are used in the synthetic industry to produce some small and large fertilizers .
截止阀 主要用在 高温、高压介质的管路或 装置上 5. Stop valve is mainly used in the pipeline or device of high temperature and high pressure medium .
  
截止阀 最明显的优点是: ♦ The most obvious advantages of globe valves are:

    . 耐磨 . Abrasion resistance ;

    . Alas .   直径 闸阀小的多 The diameter of the seat channel is much smaller than that of the gate valve ;

    . 维修方便。 . Easy maintenance.
