I. Introduction of DHH44 micro-resistance slow-closing muffler check valve
DHH44微阻缓闭消声止回阀 主要用于工业、城市给排水管道和高层住宅、高级宾涫、加压输水泵的出口处。 The DHH44 micro-resistance slow-closing muffler check valve produced by our factory is mainly used in industrial, urban water supply and drainage pipelines and high-rise residences, high-end guest houses, and outlets of pressurized water pumps. Fully consider the requirements of the use environment in the design. The use of a sloping plate structure has selected no vibration, no noise, and stable operation, ensuring that the hotel and residential environment is quiet and has energy-saving effects. By delaying the shutdown, local backflow of water is leaked into the system, thereby greatly reducing the hydraulic pressure of the backflow of the pump when it is stopped, and eliminating the occurrence of destructive water hammer peaks. The seal is made of nitrile rubber. 密封性能好、减震耐磨、使用寿命长、维修方便等特点。 HH46 type micro-resistance slow-closing butterfly check valve has good sealing performance, shock absorption and wear resistance, long service life and convenient maintenance.
