“几分”是管子的公称内径“dn”的另一个单位名称，但都有相对于的大小。1英寸

温唇 08-05 02:46

2.54厘米900cm

低智商对象 08-05 02:55

354.33英寸例如DN80,就是3"英寸2、4、5、6、8分管，管径分别是8、15、20、25mmPPR水管：PPR是英文无规共聚聚丙*（Polypropylene-Random）的简称。俗称三型聚丙*。PPR管是镀锌管，UPVC给水管，铝塑管，PE管，PE-X管，PE-RT管的更新换代产品。

没有必要较进口加大两级以上。户内较进户口一致或大一级即可。只是提醒楼主。这之间有些误差（管材的壁厚）。劳民伤财不增效。称几分的管径，管径的称呼。而现在家装使用的多为PPR管它的标称管径是外径。整栋楼的进户管4分直径也不大可能，要核实一下，它的流速和被流入的容器大小无关。就如同用一只水管分别向水壶、水池防水，是指焊管（一般是热镀锌焊管）的内径、水桶。仅和进水管的管径和压力由联系供水系统的末端稍稍加大即可

萌比从天而降 08-05 03:12

因为现在配套的水龙头。6分管一般都用作进户的主管线，这样进户管粗，所以都是用4分管铺设、角阀都是4分口4分管，水流能大点。经主阀门后都要变径成4分管的

家装用水管入户管大部分是6分的,正常情况是冷水用6分管,热水4分管。水压小的解决办法：Part1：查明低水压原因管路堵塞别忽视自来水需要经过一系列的管路才能把水输送到室内。在这一过程中，管路中各部件往往容易出现堵塞导致水压下降，但却经常被我们所忽视。一、水箱管路堵塞无论在城市还是农村，我们能经常在房子楼顶看到混凝土结构的水箱或不锈钢水塔的身影。水箱的出现是为了在非用水高峰期储水，避免用水高峰期出现水压低甚至无水可用的情况。但水箱与入室主水管的连接位置因泥沙杂物等沉积，久而久之会产生堵塞，水在源头上就被堵了，水压必然会下降。二、水管管路堵塞水管看似内部光滑，但也是管路堵塞的主要地方。尤其是在房子装修时，泥沙灰尘会被带到管路当中，除此之外，塑料水管会因为长期被太阳晒，水管内部会长满青苔;镀锌钢管会因为水管被腐蚀，有金属屑产生，这些物质都会对水管造成堵塞，从而降低水压。三、五金件管路堵塞各种五金件，尤其是卫浴五金，最容易发生堵塞。如花洒长期使用热水，特别是水质较硬的地区，花洒内部相当于一个热水壶，容易产生水垢。又如水龙头等，过于追求外观设计，出水孔太细，没有考虑实际用途，易造成堵塞，这些都是令到水压降低的原因。Part2：查明低水压原因水管降压需知晓即使你家的管路没有出现任何堵塞情况，但你家的水压仍然偏低，这时候，你就需要考虑是不是水管问题造成了水压偏低。自来水通过水管时，会与管壁产生摩擦，会与管路的弯头、接头、阀门处产生漩涡，产生阻力，从而导致水压下降。一、水管管径降压众所周知，水管的管径规格很多，常见的有4分管、6分管、1寸管等。有人为了省钱，会选择管径小的水管，有人觉得管径大的水管水压高，因此一味选择大管径水管。那么管径对水压是否有影响呢？*是：水管管径既不能太大，也不能大小。入室主水管已经一定程度决定了水的流量与压强，如果管径过大，自来水的流量满足不了室内水管的需求，会导致水压下降;如果管径过小，室内水管流量达不到自来水原有的的流量，也会导致水压下降。二、水管管网布置降压有的房屋在入住前检查水压一切正常，但经过水路改造后，发现水压不足，这种情况基本可以断定是由于水路改造所导致的，在改造过程中使用的水路管道过长、水管弯路过多、迂回角度过大等都会影响到正常的水压。三、水管漏水降压家装时都会选择把水管埋到地下，因此漏水时就难易察觉。但即使是轻微的渗漏也会严重影响水管的水压，原本完全密封的水管线路下水压是正常的，一旦出现渗漏，就会导致水压大幅度下降，进而影响正常使用。Part3：查明原因排故障解决水压低难题一、定期清理管路为防止管路堵塞带来的影响，我们应定期对管路进行清理，包括水箱、水塔、卫浴五金件等。其中水箱、水塔一般应请专业人士每隔半年消毒清洗一次；卫浴五金件可拆开清理堵塞物，或者用醋*对水垢进行清洗。尽量选用塑料水管，将水管埋在地下或铺设在阳光晒不到的地方也可防止管路堵塞。二、减少水管对水压的损耗为了减少水管对水压的损耗，水管管径应与入室主水管管径相当或比入室主水管管径小一个尺寸；水管管网布置要简洁合理，尽量避免水路管道过长、水管弯路过多、迂回角度过大等；在防止水管漏水方面，一定要对新装的水管进行打压试验，水管尽量铺在楼顶，发生漏水时容易发现。三、加装增压泵或自吸泵如果家里水压确实太低，可以尝试在水表后的管路加装一个增压泵或自吸泵。增压泵适合管路里经常有水，但压力不大的情况，而自吸泵则适合管路里水断断续续的情况，他们的原理都是为了增大水压。四、向供水部门反映情况在采取以上3种方法都未能解决水压低的问题时，你需要向当地供水部门、水厂反映情况。因为此时水压低的原因可能是附近市政供水管道管径过小，满足不了现有的用水需求，所以请供水部门调查原因以及排除问题是最有效的解决方式。
