基于机械自力式原理的压力无关型风量控制阀在暖通行业具有广阔的应用前景,为帮助国内企业提高产品质量,搭建了一种新的性能测试装置,并阐述了装置中风量的测量方法。对某款国产风量控制阀的测试结果表明:该装置能模拟压力无关型风量控制阀的实际工况,为改善产品设计提供了条件。
Pressure independent valve based on mechanical self-force principle has broad application prospects in HVAC industry. To help domestic enterprises to improve product quality, a new performance testing device is set up, and the measurement method of air volume in the device is described. The test results of a certain domestic air volume control valve show that the device can simulate the actual working condition of the pressure independent air volume control valve and provide the conditions for improving the product design.
