This article provides expert advice on selecting gate valves for circulating water systems. Wedge single gate valves are suitable for conventional industrial systems, good sealing but need clean water; resilient gate valves are suitable for large systems, strong sealing and adaptable to changes in pressure and temperature; and concealed stem gate valves are suitable for small building systems, compact and easy to operate. Selection needs to be comprehensive system size, water quality, pressure and temperature and other factors to ensure efficient and stable operation.

在工业生产及建筑暖通等多个领域中,循环水系统得到了广泛的应用。其中,gate valve作为控制水流的核心组件,其选择对系统运行至关重要。

在常规工业循环水系统中,楔式单闸板闸阀因其结构简洁、制造技术成熟、成本较低而受到青睐。这种闸阀具有良好的密封性,能有效避免循环水泄漏。同时,其闸板与阀座的接触面积适中,开启和关闭时水流阻力小,有助于降低能源消耗。然而,它对介质的清洁度有一定要求,若水中有较多杂质,可能影响密封效果。

对于密封性要求较高的大型循环水系统,弹性闸板闸阀更为适宜。弹性闸板能够在不同工况下自动调整与阀座的接触程度,即便在温度和压力变化较大时,也能保持良好的密封性能。此外,它能够适应复杂的水质情况,具有较强的抗杂质能力。

在小型建筑循环水系统中,Concealed rod gate valve是一个不错的选择。其结构紧凑,占用空间小,操作便捷,且价格亲民,足以满足小型系统的基本需求。

综上所述,在挑选循环水系统所需的闸阀时,需综合考虑系统规模、水质、压力、温度等多方面因素,以确保闸阀能够稳定且高效地运行。
