上海申弘閥門有限公司主營閥門有:減壓閥(氣體減壓閥,可調(diào)式減壓閥,波紋管減壓閥,活塞式減壓閥,蒸汽減壓閥,先導(dǎo)式減壓閥,空氣減壓閥,氮?dú)鉁p壓閥,水用減壓閥,自力式減壓閥,比例減壓閥)是適用于城市煤氣、液體石油氣、天然氣、燃?xì)獾榷喾N煤氣為加熱燃燒介質(zhì)管路做二位式通斷切換,進(jìn)行溫度自動控制的執(zhí)行機(jī)構(gòu)。它廣泛應(yīng)用于紡織業(yè)、印刷業(yè)的煤氣加熱定型和玻璃、燈泡業(yè)的窯爐加熱及其它行業(yè)的煤氣加熱自控系統(tǒng)。
【ZCM燃?xì)怆姶砰y】工作原理:
【ZCM燃?xì)怆姶砰y】常閉型
ZCM煤氣電磁閥DNl5—50系一次開閥的直動式低壓電磁閥,DN65—300系二次開閥的先導(dǎo)式電磁閥。直動式電磁閥在接受電信號后,電磁力直接將閥塞提起,介質(zhì)流通;斷電后,電磁力消失,閥塞在自重和彈簧力作下下落,介質(zhì)斷流。先導(dǎo)式電磁閥在接受電信號后,銜鐵在電磁力作用下先帶動副閥閥塞捉起,主閥膜片上流體經(jīng)副閥流走,減少了作用在主閥膜片上的壓力,當(dāng)主閥膜片上的壓力減少到一定值時(shí),銜鐵帶動主閥膜片,并利用壓差使主閥打開,介質(zhì)流通;線圈斷電后,電磁力消失,銜鐵因自重下落復(fù)位,同時(shí)依靠介質(zhì)壓力,主閥得以緊密關(guān)閉。
【ZCM燃?xì)怆姶砰y】常開型
ZCM煤氣電磁閥應(yīng)用*的直動式結(jié)構(gòu),當(dāng)給電磁頭的線圈通電時(shí), 位于線圈周圍的靜鐵芯組件便產(chǎn)生磁性,磁力克服閥桿組件重力和回位彈簧彈力后將動鐵芯連同閥桿組件向上吸起,從而使固連在閥桿組件上的閥盤與閥座緊密貼緊而密封, 閥門關(guān)閉;斷電后,閥盤在回位彈簧及閥桿組件重力作用下恢復(fù)原位,閥門開啟,管道恢復(fù)正常通氣

在截止閥管件行業(yè)中,根據(jù)公稱壓力PN的大小,我們可以把公稱壓力小于等于1.6MPa的閥門為低壓閥門,公稱壓力為2.5MPa、4.0MPa、6.4MPa的閥門為中壓閥門,同時(shí)我們也經(jīng)常會提到1.6MPa壓力、2.5MPa壓力和多少公斤壓力、多少個標(biāo)準(zhǔn)大氣壓等之類的術(shù)語,那么1MPa壓力到底有多大壓強(qiáng),1MPa壓力等于多少公斤壓力呢蒸汽壓力為2.5㎏是表示2.5kg/cm2,是表示的單位面積上的壓力--壓強(qiáng),通常俗稱為2.5kg壓力。新的表示方法約為0.25MPa。
換算關(guān)系:1kg/cm2=0.098MPa,因此壓力2.5kg/cm2=0.245MP,可約等于0.25MPa.ISO標(biāo)準(zhǔn)帕斯卡(1Pa=1N/m2)
1公斤力/平方厘米=98.0665千帕
粗算時(shí)常按1公斤力=10N 則:
1公斤力/平方厘米=100千帕=1bar=0.1MPa
10公斤力/平方厘米=1000千帕=1MPa
公斤的單位是質(zhì)量單位
MPA是壓力的單位
質(zhì)量m=壓力/重力加速度
壓力p=壓力/面積
這是他們之間的關(guān)系
1公斤壓力指的是1公斤重的物體作用為1cm2面積上所產(chǎn)生的壓強(qiáng),可以想像一下,1公斤重(比兩瓶一元錢的康師傅礦泉水重略輕)的物體全部壓在一個手指頭上所產(chǎn)生的壓強(qiáng)。 我們來計(jì)算一下, 1MPa=1×106Pa 1Pa=1N/1m2 1MPa=106N/m2=106N/104cm2=100N/cm2 重力加速度g約等于9.8 N/KG,為方便計(jì)算,g按整數(shù)10。 1KG的物體重力=1KG×10N/KG=10N 1公斤壓力是1KG的重力作用于1cm2面積上產(chǎn)生的壓強(qiáng),即 1公斤壓力=10N/cm2 1MPa=100N/cm2=10×10N/cm2 即1MPa壓力等于10公斤壓力。
單位說明: Pa,壓強(qiáng)單位,中文名稱為“帕斯卡”,簡稱“帕”,即牛/平方米,1帕=1牛/平方米 M,數(shù)量單位,M即million,數(shù)值為一百萬 N,物理力學(xué)單位,簡稱牛,是一種衡量力的大小的單位,兩個雞蛋的重力約為1N(0.1千克的物體的重量) m,長度單位,米 m2,面積單位,平方米 cm2,面積單位,平方厘米 KG,重量單位,千克,公斤
