Product Name:
DS/J61 H/Y-25-64 welded seal globe valve
Description:

焊接式水封截止阀 DSJ61H

水封式截止阀 DS/J61 H/Y-25-64
主要尺寸及重量(mm)
DS系列水封阀门适用于公称压力≤4 DMPa,工作温度≤400℃或≤550℃,工作介质为水蒸汽油品和非腐蚀性气体的管路上作启闭装置用.尤其适用于火电厂汽机真空冷凝系统有截止阀和闸阀两种形式

尺寸图
一、结构与性能特点:
1结构形式:阀盖填料室具有水循环密封结构,当接口通人压力为0 6~l 0MPa的水时.可使系统与大气隔离,保证系统具有良好的气密性.
2连接形式:承插焊连接.法兰连接和焊接连接.
3驱动方式:手动和电动.
4 DS/Z型系列采用双闸板双向弹性密封、启闭灵活迅速密封可靠;真空隔断截止阀 阀杆与阁瓣采用动连接,阀瓣与阀座垂直座封;启闭行程和阀门高度小.
5产品结构简单紧凑合理检修方便使用寿命长.
6在管路上作启闭置用.必须处于全开或全闭状态,不得用于调节流量.
