品牌：RETZ/我们一直致力于流体控制和测控领域的持续创新，始于2005……进口活塞式蒸汽减压阀采用高效先导阀式结构设计，准确且稳定地调整所需的二次蒸汽压力The piston type steam pressure reducing valve adopts an efficient pilot valve structure design, accurately and stably adjusting the required secondary steam pressure
进口活塞式蒸汽减压阀产品详情product details
活塞式减压阀主要工作部件一曲面活塞及三重定位结构，在高速蒸汽汽流的冲击下，也能保证准确动作。相比于传统直边式活塞及双线定位的曲面活塞结构，最显著的优势是彻底解决了因活塞卡位、粘缸、拉缸现象而造成减压阀失效等常见问题，确保.阀后二次压力稳定 RETZ main working part of the piston type steam pressure reducing valve is a curved piston and a triple positioning structure, which can also ensure accurate action under the impact of high-speed steam flow. Compared with the traditional straight side piston and the double line positioning curved piston structure, the most significant advantage is that it completely solves the common problems such as the failure of the pressure reducing valve caused by the piston clamping, cylinder sticking and cylinder pulling, and ensures the stability of the secondary pressure behind the valve
进口活塞式蒸汽减压阀性能特点∶ Performance characteristics
1.独特的自润滑、排渣活塞结构设计，确保长效稳定控制 Unique self-lubricating and slag discharge piston structure design ensures long-term stable control
2.内置先导阀结构，即使在供汽负载不稳定，和后端设备用汽量变化较大时，其迅速响应的先导反馈信号，也可确保阀后二次压力非常稳定 Built in pilot valve structure, even when the steam supply load is unstable and the steam consumption of the back-end equipment changes greatly, the rapid response of the pilot feedback signal can ensure that the secondary pressure behind the valve is very stable
3.主阀与导阀的阀瓣阀座密封面，均采用抗冲蚀、抗磨损、耐腐蚀的Stellte硬质合金材料，并进行镜面加工处理阀芯内件均由不锈钢制成。以确保减压的长效控制，且更经久耐用 The sealing surfaces of the valve disc and valve seat of the main valve and the pilot valve are made of stellte hard alloy material with erosion resistance, abrasion resistance and corrosion resistance, and are mirror processed. The inner parts of the valve core are made of stainless steel. To ensure long-term control of pressure reduction and more durable
4.压力反馈平衡管为内置式结构，安装简单 Pressure feedback balance pipe is built-in structure, easy to install
5.独特的入口端，导阀内部和活塞下部（DN65以上口径）三重过滤单元，解决了杂质卡堵等常见问题 The unique inlet end, the inner part of the pilot valve and the lower part of the piston (diameter above DN65) triple filter unit solve common problems such as impurity blockage
6.减压比10∶1。当设定压力大于2barg且口径为DN65以上时，建议选用活塞式减压阀 The decompression ratio is 10:1. When the set pressure is greater than 2barg and the diameter is above DN65, it is recommended to select the piston type pressure reducing valve
