进口蒸汽减压阀【控制精度高】德国莱克LIK阀门
进口蒸汽减压阀由主阀和导阀两部分组成，该系列产品在普通减压阀基础上做了以下改进,加大了活塞面积,改变了节流结构,改变了密封形式,改 进了导阀结构和调节弹簧形式,主阀主要由阀座、主阀盘、活塞、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。性能的 提高的表现形式有改善了流线分布，降低了噪声，与此同时也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，在密封面结构进行了改进延长了密封面寿命。高灵敏度蒸汽减压阀的特性。

High sensitivity steam pressure reducing valve consists of two parts, the main valve and pilot valve, this series of products based on the ordinary pressure reducing valve made the following improvement, increased the piston area, changed the structure of throttling, changed the seal form, improve the pilot valve structure and regulation of the spring form, the main valve is mainly composed of valve seat, the main valve, piston, spring and other parts. Pilot valve is mainly composed of the seat, disc, diaphragm, spring, adjusting spring and other parts. By adjusting the adjusting the spring pressure setting outlet pressure, the use of diaphragm sensing outlet pressure changes, through the pilot valve opening and closing drive piston to adjust the size of the main valve throttle position over-current, realize the function of reduced pressure regulator. Could improve the expression form of improving the performance of the streamline distribution, reduces the noise, at the same time also improves the sensor performance to the outlet pressure changes, improves the sensitivity, greatly reduces the due to changes in upstream pressure, pressure caused by the change in the flow deviation, in the sealing surface structure is improved to extend the working life of the sealing surface
