乘银集中供热换热站二次网补水系统现有补水采用水箱补水方式,原设计补水方式采用电磁阀开关控制实现一次网对二次网的补水,但在实际应用过程中发现由于在不同时段时补水量是有较大差距的,电磁阀的开关使得补水通过量是恒定的,如把电磁阀前端阀门设定较大虽满足了失水高峰期的补水需求,但夜间失水较少时,又会造成超压补水现象,导致二次网热用户暖气片爆裂现象。
By the silver central heat exchanger station secondary network water system, the existing replenishment water tank replenishment method, the original design of water replenishment method using electromagnetic valve switch to achieve a network of secondary network replenishment, but found in the actual application process due to different The time when the amount of water is a big gap, the solenoid valve makes the amount of water through the switch is constant, such as the valve solenoid valve front set larger to meet the loss of water peak demand, but less water loss at night When, will cause overpressure replenishment phenomenon, leading to secondary network hot user radiator burst phenomenon.
