摘　　要：为了切合国家规范对水力平衡的要求,本文结合常用的一次泵定流量系统与一次泵变流量系统,给出了一种实现水力平衡的方法——通过计算确定了必须设置平衡阀的支路,并对不设平衡阀的支路进行合理的阻力分配,使其实现自然的平衡。计算结果表明,通过该方法,仅需配置有限的平衡阀即可实现全面的水力平衡,既实现了节能,亦节约了投资成本。In order to meet the requirements of state regulations for hydraulic balance,combined with the commonly used constant primary flow system and variable primary flow system,a kind of hydraulic balance calculation method is given in this paper.It must set the balancing valve was determined by the calculation of the branch,and reasonably distribute the resistance in the branch of the balancing valve is not set up,make it realize the balance of nature.The calculation results show that the hydraulic balance can be achieved by using only a limited number of balanced valves,which can achieve both energy saving and investment.
