进口高温蒸汽减压阀产品简介:
进口高温蒸汽减压阀,High temperature steam reducing valve,是指用于高温热蒸汽或者高温饱和蒸汽场合,比如蒸汽温度为200℃,蒸汽温度250℃,蒸汽温度300℃,蒸汽温度400℃,蒸汽温度450℃的蒸汽管道,能将阀前的蒸汽压力减到所需要的出口压力,并将压力稳定在所需要的压力值的减压阀,属于可调式先导活塞式减压阀。由主阀和导阀两部分组成。主阀主要由阀座、阀阀盘、活塞、缸套、弹簧等零件组成。导阀主要由阀座、阀瓣、膜片、弹簧、调节弹簧等零件组成。通过调节调节弹簧压力设定出口压力,利用膜片传感出口压力变化,通过导阀启闭驱动活塞调节主阀节流部位过流面积的大小,实现减压稳压功能。进口高温蒸汽减压阀主要用于高温蒸汽管路,起到减压稳压作用。
 
Brief introduction of imported high temperature steam pressure reducing valve:
 
High temperature steam reducing valve imported from German rock "de lock" Valve is used for high temperature hot steam or high temperature saturated steam occasions, such as steam temperature of 200 ℃, steam temperature of 250 ℃, steam temperature of 300 ℃, steam temperature of 400 ℃ and steam temperature of 450 ℃. It can reduce the steam pressure in front of the valve to the required outlet pressure and stabilize the pressure at the required pressure value. It belongs to the adjustable pilot piston type pressure reducing valve Pressure valve. It consists of main valve and pilot valve. The main valve is mainly composed of valve seat, valve disc, piston, cylinder liner, spring and other parts. The pilot valve is mainly composed of valve seat, disc, diaphragm, spring, adjusting spring and other parts. Through adjusting the spring pressure to set the outlet pressure, the diaphragm is used to sense the change of outlet pressure, and the pilot valve is opened and closed to drive the piston to adjust the size of the main valve throttling area, so as to realize the function of pressure reduction and pressure stabilization. The imported high temperature steam pressure reducing valve is mainly used in high temperature steam pipeline to reduce pressure and stabilize pressure.
 
进口高温蒸汽减压阀结构特点:
1、提高了对出口压力变化的传感效能,提高了灵敏度,大大降低了因上游压力变化,流量变化等因素引起的压力偏差。
2、改善了流线分布,降低了噪声。
3、改进了密封面结构,延长了密封面寿命。
4、本质安全,可用于危险区域(E型除外)。
 
Structural features of imported high temperature steam pressure reducing valve:
1. It improves the sensing efficiency and sensitivity of outlet pressure change, and greatly reduces the pressure deviation caused by upstream pressure change and flow rate change.
 
2. The streamline distribution is improved and the noise is reduced.
 
3. The structure of the sealing surface is improved and the service life of the sealing surface is prolonged.
 
4. Intrinsically safe, can be used in hazardous areas (except type E).

阀门是一种用途极为广泛的设备,几乎可以在任何地方找到,阀门活跃在街道下、房屋里、发电厂和造纸厂、精炼厂以及各种各样的基础设施和工业设施中。也可以理解为我们日常生活中都离不开阀门了。
