■主要特点及用途
1、本产品的阀盖填料室具有水密封结构,当接口通入压力0.6~1MPa的水时,可使系统与大气隔离,保证系统具有良好的气密封。
2、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。
3、产品结构简单、紧凑合理、检修方便、使用寿命长。
4、在管路上作启闭装置用,必须处于全开或全闭状态,不得用于调节流量。
5、阀门连接方式有法兰和焊接两种,驱动方式为手动和电动。
6、Ds系列水封阀门适用于公称压力≤10.OMPa,工作温度≤425℃,工作介质为水、蒸汽、油品和非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。
■Chief features and usages
1.c chamber of packing of the valve’s Bonnetis of a water-sealed structure which, when the water of 0.6-1 MPa pressur goesinto the mouthpiece.can make the system isolated from air to ensure the system with a goodieak prootness.
2.ModeiDS/Z series use duai-gate dual-direction elastic seaiings, being flesible and fast to open and close.reliable sealing.
3.Simpie compact and reaso able st ructure easy to overhaulandiong duration
4.When to be used as the open and close device on pipeiines,it must bein fully-opened or fuily-closed state and unallowed to be used for flow adjustment.
5 Two ways of connection by flange and weiding two driving ways manually and elect ricallyg.
6.Sujtable to act as the open and close devjce for the pjpelines with the working medium of water, steam oilgoods and noncor rosive gas, especially for the vacuum condensation of the steam turbinein steam power palnts
