摘要
为了配合《民用建筑节水设计标准》（GB50555-2010）的编制和实施，依据《节水型生活用水器具》（CJ1642002），利用开发的新型试验测试装置，对目前北京市场上占有率较高的10种水龙头和2种2000年北京市政府向市民免费发放的水龙头在不同压力下的节水性能进行了测试研究。研究结果发现：仅有3种水龙头符合国家标准，不符合标准的水龙头浪费水十分严重；符合标准的水龙头在超压时也会不同程度造成水的浪费，建议当供水压力大于0．2MPa时，设置减压装置；2种水龙头在压力0．05～0．2MPa时，流量随着压力的上升而增加，为0．13～0．21L／s；压力〉0．2MPa时，流量反而下降，基本维持在0．15～0．16L／s。
To cooperate the edition and implementation of the ＂Standard for water-savzng design in civil building （GB 50555--2010）＂, according to the ＂Domestic water saving devices （CJ 164--2002）＂, the performance tests of the ten kinds of taps, which occupy high shares in Beijing, and other two kinds of taps, which are free from Beijing government, under different pres- sures are carried out in this paper. The results show： only three kinds of taps meet the national standard, and others waste water severely; those taps meeting national standard will waste water to various degrees if the pressure is beyond limitation, so it is advised that the pressure should be reduced when it is above 0. 2 MPa; flow rate of two kinds of taps will increase from 0. 13 to 0. 21 L/s with the increase of pressure if the pressure is from 0. 05 to 0. 2 MPa, and when the pressure is beyond 0. 2 MPa the flow rate will decrease with the growing pressure and basically keep between 0. 15 to 0. 16 L/s.
