有些水龙头拧开时,会发出刺耳的噪声,其原因有几种:1.自来水管里有空气。水管里的空气排出时,声音嘶哑,也不刺耳;管里的空气排出后,噪声依旧。2.水龙头漏气。有些住户因此把整个水龙头换掉,果然噪声消失,但解释不通,因为管里水压大于管外大气压,若是水龙头漏了,只能水漏出,不致气漏入。3.水管支架未紧固。水管支架未紧固(尤其悬臂过长),有时会发出低沉的声音,水管也微微振
Some water taps make a harsh noise when they are unscrewed. There are several reasons: 1. There is air in the water pipe. When the air in the water pipe was discharged, it was hoarse and not harsh; the noise remained after the air in the pipe was discharged. 2. The faucet leaks. Some tenants have therefore replaced the entire faucet, and as a result, the noise disappeared, but it was impossible to explain because the water pressure in the pipe was greater than the atmospheric pressure outside the pipe. If the faucet leaked, only the water leaked out and no leakage of air occurred. 3. The water pipe bracket is not fastened. The water pipe bracket is not fastened (especially the cantilever is too long), sometimes it will send a deep sound, and the water pipe will also be slightly vibrated.
