一种新型蒸汽管网节能装置—一Y42H-16先导薄膜式减压阀,由青岛疏水阀厂研制成功.并于近日通过鉴定.与当今国内通用的“活塞式减压阀”、“波纹管式减压阀”相比,该减压阀的使用寿命延长了五至六倍,渗透量小于最大流量的千分之三.专家们鉴定认为,该减压阀为国内首创,各项指标均达到国外同类设备的先进水平.
A new type of steam pipe network energy-saving device - a Y42H-16 pilot membrane valve developed by the Qingdao Trap Factory successfully developed and recently passed the identification and today’s domestic common “piston valve,” “bellows Type valve ”compared to the life of the valve to extend the five to six times the penetration of less than the maximum flow of three thousandths. Experts believe that the valve is the first domestic initiative, the indicators are To reach the advanced level of similar foreign equipment.
