Introduction of Yz11X type direct acting membrane branch pressure reducing valve

直接作用薄膜式支管减压阀 是直接作用式薄膜弹簧减压阀,是在吸取了国外同类产品优点的基础上设计制造的。 This series of direct acting diaphragm branch pressure reducing valve is a direct acting diaphragm spring pressure reducing valve, which is designed and manufactured on the basis of absorbing the advantages of similar foreign products. It is mainly composed of diaphragm, diaphragm valve, adjusting spring and other parts. The diaphragm is used to sense the downstream pressure change to drive the valve flap, change and control the valve opening degree to achieve the function of pressure reduction and pressure stabilization. Set the outlet pressure value by setting the adjustment spring pressure.
杠杆式蒸汽减压阀 适当加大了膜片面积,提高了灵敏度。 The lever type steam pressure reducing valve appropriately increases the diaphragm area and improves the sensitivity. Decompression and voltage stabilization are stable and sensitive. It is suitable for the branch pipelines of high-rise apartment buildings and residential areas, as well as the household branch pipes of apartments and houses.
