(活塞式)進口蒸汽減壓閥 主要技術參數及性能 Main technical parameters and performance

活塞式減壓閥主要工作部件一曲面活塞及三重定位結構，在高速蒸汽汽流的沖擊下，也能保證準確動作。相比于傳統直邊式活塞及雙線定位的曲面活塞結構，最顯著的優勢是徹底解決了因活塞卡位、粘缸、拉缸現象而造成減壓閥失效等常見問題，確保.閥后二次壓力穩定 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

規格說明 Description

注∶閥體壓力為2.5MPa，工作壓力為1.6MPa，壓力偏差不大于±0.002MPa Note: the valve body pressure is 2.5MPa, the working pressure is 1.6Mpa, and the pressure deviation is not more than ± 0.002mpa

性能特點∶ Performance characteristics

1.獨特的自潤滑、排渣活塞結構設計，確保長效穩定控制  Unique self-lubricating and slag discharge piston structure design ensures long-term stable control

2.內置先導閥結構，即使在供汽負載不穩定，和后端設備用汽量變化較大時，其迅速響應的先導反饋信號，也可確保閥后二次壓力非常穩定  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.主閥與導閥的閥瓣閥座密封面，均采用抗沖蝕、抗磨損、耐腐蝕的Stellte硬質合金材料，并進行鏡面加工處理閥芯內件均由不銹鋼制成。以確保減壓的長效控制，且更經久耐用  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.壓力反饋平衡管為內置式結構，安裝簡單  Pressure feedback balance pipe is built-in structure, easy to install

5.獨特的入口端，導閥內部和活塞下部（DN65以上口徑）三重過濾單元，解決了雜質卡堵等常見問題  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.減壓比10∶1。當設定壓力大于2barg且口徑為DN65以上時，建議選用活塞式減壓閥 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
