通过地漏综合测试机测试三种结构地漏(水封式、机械密封式与混合密封式)的本体性能,并参考《地漏》(GB/T 27710—2011),分析地漏性能相关测试指标。结果表明,三种地漏防返溢性能测试结果都为溢水,向上溢水的时间都在1s左右,与《地漏》(GB/T 27710—2011)要求保持(30±2)min的规定相距甚远;三种地漏的排水流量和自清能力都符合规范要求,建议排水流量指标应该与自清能力指标建立相应的联系,共同评价地漏性能;水封式地漏和混合密封式地漏的水封损失都非常小,完全满足20 mm的水封剩余深度要求,具有非常良好的水封稳定性。
The performance of the three kinds of floor drain (water seal, mechanical seal and hybrid seal) was tested by the floor drain comprehensive testing machine, and the floor drain related test index was analyzed with reference to “floor drain” (GB / T 27710-2011). The results showed that all the three leak-proof test results were overflow and overflowing for about 1 second, far away from the requirement of “(32 ± 2) min” for “floor drain” (GB / T 27710-2011) ; Three kinds of floor drain drainage flow and self-cleaning capacity are in line with regulatory requirements, the proposed drainage flow indicators should be established with the self-cleaning capacity indicators corresponding to jointly evaluate the floor drain performance; water seal floor drain and hybrid seal floor drain water seal loss are Very small, fully meet the residual depth of 20 mm water seal requirements, has a very good water seal stability.
