　　主要性能 Main performance进口气动调节阀.jpg

　　(水，气)进口蒸汽安全阀用在锅炉、压力容器、管路等受压设备上作为超压保护装置。当被保护设备内介质压力异常升高，超过规定值进口蒸汽安全阀.jpg时，阀门自动开启，继而全量排放，以防止压力继续升高，当压力降低到规定值时，阀门自动关闭，保证设备正常运行 RETZ Imported steam safety valves are used as overpressureprotection devices on pressure equipment such as boilers, pressure vessels andpipelines. When the medium pressure in the protected equipment rises abnormallyand exceeds the specified value, the valve will automatically open and thendischarge the full amount to prevent the pressure from rising continuously.When the pressure drops to the specified value, the valve will automaticallyclose to ensure the normal operation of the equipment.

　　进口蒸汽安全阀性能特点∶ Performance characteristics

　　排量大,内部阀体在设计上能够提供良好的流动剖面 Largedisplacement, internal valve body can provide good flow profile in design

　　采用自定心阀塞,对密封面进行平衡处理，使其高度密封 Selfcentering valve plug is used to balance the sealing surface to make it highlysealed

　　配备作杆dingweiqi的螺纹轴，便于即时手动操作 Equipped with a threaded shaft as a rod positioner for immediate manualoperation

　　提升器采用不受密封影响的设计，使阀门在蒸汽膨胀时容易立即开启，保证准确地控制阀门的开闭 The lifteradopts a design that is not affected by sealing, so that the valve can beeasily opened immediately when the steam expands, and the opening and closingof the valve can be accurately controlled
