　　进口对夹止回阀 对夹升降式逆止阀 对夹式弹簧单向阀性能描述 performancedeion

　　对夹升降式止回阀主要构成由阀体、阀瓣、弹簧等组成，可以水平或垂直安装于多种管路系统，防止介质倒流，具有结构短、体积小、质量轻等优点。该阀的阀瓣关闭快速，水锤压力小流道通畅，流体阻力小，动作灵敏，密封性能好。主要适用于清净介质，不宜用于含有固体颗粒和粘度较大介质的管路中。可安装于水泵出口处，能避免产生水锤、水击声和破坏性冲击，达到防止逆流和保护设备的目的，有较好节能效果the clamp lift checkvalve mainly consists of a valve body, disc, spring, etc. it can be installedhorizontally or vertically in various pipeline systems to prevent medium backflow,and has advantages such as short structure, small volume, and light weight. thevalve disc of this valve closes quickly, the water hammer pressure is small,the flow channel is unobstructed, the fluid resistance is small, the action issensitive, and the sealing performance is good. mainly suitable for cleaningmedia, not suitable for pipelines containing solid particles and medium withhigh viscosity. it can be installed at the outlet of the water pump to avoidwater hammer, water hammer sound, and destructive impact, achieving the purposeof preventing reverse flow and protecting equipment, with good energy-savingeffect.
