ppr水管在連接時(shí),，無旋轉(zhuǎn)地把管端導(dǎo)入加熱套管內(nèi),，插入到所標(biāo)志的---,，同時(shí)無旋轉(zhuǎn)地把管件推到加熱管上,，達(dá)到規(guī)定標(biāo)志處,。一般地可用心中默讀數(shù)字法掌握加熱時(shí)間,，或觀察管件,、管材的加熱程度，當(dāng)模頭上出現(xiàn)一圈ppr熱熔凸緣時(shí),，即可將管材,、管件從模頭上取下進(jìn)行下道工序。
when the ppr water pipe is connected,， the pipe end is led into the heating sleeve without rotation&inserted to the marked depth. at the same time,， the pipe fitting is pushed onto the heating pipe without rotation to reach the specified mark. generally， the heating time can be mastered by reading numbers in heart,，/the heating degree of pipe fittings&pipes can be observed. when a circle of ppr hot-melt flange appears on the die head,， the pipe&pipe fittings can be removed from the die head for the next process.
水閥
水路改造時(shí)，記得家里要安裝一個(gè)總水閥,，用來開啟和關(guān)閉水流,。這樣家中發(fā)生漏水,，或者需要更換水閥的時(shí)候，不用跑到樓下關(guān)水,。水閥可以安裝在水槽下方,，不占空間。水閥價(jià)格比較貴,，如果,，pvc管業(yè)制造，你不提醒,，工人不一定給你裝,，涪陵區(qū)pvc管業(yè)，等瓷磚貼好再發(fā)現(xiàn)就遲了,。
water valvewhen rebuilding waterways,， remember to install a main water valve at home to open&close the water flow. in this way， when there is leakage in the house/the tap needs to be replaced,， there is no need to run downstairs to turn off the water. the water valve can be installed under the water tank without occupying space. the price of water valve is more expensive. if you dont remind,，pvc管業(yè)， the workers dont have to install it for you. its too late to find it after the tiles are pasted.
ppr管材料的耐水性用軟化維卡系數(shù)表示,。在采暖,、高溫?zé)崴⒚鞣蟀惭b,、戶外給排水管道應(yīng)用中耐水性材料的軟化維卡系數(shù)具有明顯的優(yōu)勢(shì),。軟化系數(shù)的大小，pvc管業(yè)加盟,，表明材料浸水后強(qiáng)度降低的程度,，一般波動(dòng)在0-1之間。軟化系數(shù)越小,，說明材料吸水飽和后的強(qiáng)度降低越多,，所以其耐水性越差。對(duì)于經(jīng)常位于水中或受潮---的重要結(jié)構(gòu)物的材料,，其軟化系數(shù)不宜小于,。受潮較輕的或次要結(jié)構(gòu)物的材料，其軟化系數(shù)不宜小于0.75,。軟化系數(shù)大于0.80的材料,，通常可以認(rèn)為是耐水的材料,。
