摘　　要：基于斜盘防振动防水锤止回阀(SKCV)项目案例,对斜盘止回阀开展创新性设计。针对原有管道关阀时水锤波的消除问题和开阀时因流速波动而引起的阀瓣抖动问题展开研究,旨在弥补原有设计的不足。通过设计泄压防水锤装置和扭簧防振动装置,有效解决了低压关闭、水锤波冲击伤害、全开或某一开度时振动等问题。对于管道系统和水泵出口端的止回阀而言,在低背压、污水系统、流速波动较大的工况下,本文创新性地设计出具有预防水锤波、降低振动副、结构相对合理、维修操作便利、摩擦阻尼相对较低等特性的止回阀产品,实现了对于阀门领域内技术难题的攻克,并取得了显著的止回阀设计研发成果。Based on the project case of the Swing Check Valve with Inclined Disc for Anti-Vibration and Water Hammer Prevention(SKCV),this study conducts innovative design improvements for the inclined disc check valve.The research focuses on addressing the issues of water hammer wave elimination during pipeline valve closure and disc vibration caused by flow rate fluctuations during valve opening,aiming to overcome the limitations of the original design.By designing a pressure-relief water hammer prevention device and a torsion spring anti-vibration device,the problems of low-pressure closure,hammer impact,and vibration at full or partial opening are effectively resolved.For the check valve at the outlet of the pipeline system and the pump,under the conditions of low back pressure,sewage system and large fluctuation of flow rate,this paper innovatively designs a check valve product with the characteristics of preventing water hammer wave,reducing vibration pair,relatively reasonable structure,convenient maintenance and operation,and relatively low friction damping,which realizes the overcoming of technical problems in the field of valves,and has achieved remarkable results in the design and development of check valves.
