進(jìn)口消聲止回閥德國洛克品牌產(chǎn)品優(yōu)勢
進(jìn)口消聲止回閥優(yōu)點(diǎn):
1、此閥可立式、臥式安裝,閥瓣升降靈活,且運(yùn)行平穩(wěn)、噪音底、安全、極少有故障。
2、結(jié)構(gòu)合理、密封性能好。
3、耐磨損,使用壽命長。
進(jìn)口消聲止回閥描述:
德國《DE LOCKE》洛克進(jìn)口消聲止回閥閥瓣采用進(jìn)出口兩端中心軸導(dǎo)向,啟閉靈活,定位準(zhǔn)確,可水平安裝或垂直安裝,閥瓣采用彈簧加載,其快速的關(guān)閉能有效地減少水錘壓力。密封面采用O形圈彈性密封與金屬硬密封的組合密封結(jié)構(gòu),密封性能好,關(guān)閉時(shí)無噪聲。還具有體積小、重量輕、流體阻力小、結(jié)構(gòu)長度小、耐疲勞、壽命長等特點(diǎn)。該閥門安裝于給排水、消防、暖通系統(tǒng)可安裝于水泵出口處,防止回水倒流,而對泵造成損壞。
進(jìn)口消聲止回閥技術(shù)參數(shù):
1、規(guī)格范圍:DN40-DN400
2、溫度范圍:-5℃≈150℃
3、壓力范圍:PN16
4、閥體材質(zhì):鑄鐵、WCB
5、閥桿材質(zhì):304/銅
6、閥蓋材質(zhì):和本體一樣
7、閥板材質(zhì):304/銅
8、連接方式:法蘭
9、適用范圍:水

進(jìn)口消聲止回閥安裝與維護(hù):
1,本閥門通路兩端須堵塞,存在干燥通風(fēng)的室內(nèi)。如長期存放,應(yīng)經(jīng)常檢查防銹蝕。
2,安裝前應(yīng)將閥門清洗干凈,并消除在運(yùn)輸過程中造成的缺陷。
3,安裝時(shí)必須仔細(xì)核對閥門上的標(biāo)志和銘牌是否符合使用要求。
4,升降式垂直瓣止回閥應(yīng)安裝在垂直管道上。
5,升降式水平瓣止回閥應(yīng)安裝在水平管道上。
6,在管線中不要使止回閥承受重量,大型的止回閥應(yīng)獨(dú)立支撐,使之不受管系產(chǎn)生的壓力的影響。
7,安裝止回閥時(shí),應(yīng)特別注意介質(zhì)流動(dòng)方向,應(yīng)使介質(zhì)正常流動(dòng)方向與閥體上指示的箭頭方向相一致,否則就會(huì)截?cái)嘟橘|(zhì)的正常流動(dòng)。底閥應(yīng)安裝在水泵吸水管路的底端。
8,通式升降式止回閥應(yīng)安裝于水平管路上,立式升降式止回閥和底閥一般安裝在垂直管路上,并且介質(zhì)自下而*動(dòng)。
9,止回閥關(guān)閉時(shí),會(huì)在管路中產(chǎn)生水錘壓力,嚴(yán)重時(shí)會(huì)導(dǎo)致閥門、管路或設(shè)備的損壞,尤其對于大口管路或高壓管路,故應(yīng)引起止回閥選用者的高度注意。
Installation and maintenance of inlet silencing check valve:
1. Both ends of the valve passage must be blocked, and there is a dry and ventilated room. If it is stored for a long time, it should be checked frequently for anti-corrosion.
2. Clean the valve before installation and eliminate the defects during transportation.
3. During installation, it is necessary to carefully check whether the marks and nameplates on the valve meet the use requirements.
4. The lift type vertical disc check valve shall be installed on the vertical pipeline.
5. Lift type horizontal disc check valve shall be installed on horizontal pipeline.
6. Don't make the check valve bear weight in the pipeline. Large check valves should be supported independently, so that they are not affected by the pressure generated by the piping system.
7. When installing the check valve, special attention should be paid to the flow direction of the medium, so that the normal flow direction of the medium is consistent with the direction of the arrow indicated on the valve body, otherwise the normal flow of the medium will be cut off. The bottom valve shall be installed at the bottom of the water pump suction pipe.
8. The general lift check valve should be installed on the horizontal pipeline, while the vertical lift check valve and bottom valve are generally installed on the vertical pipeline, and the medium flows from bottom to top.
9. When the check valve is closed, it will produce water hammer pressure in the pipeline, and in serious cases, it will cause damage to the valve, pipeline or equipment, especially for the large mouth pipeline or high-pressure pipeline, so the check valve selector should pay close attention to it.
