style="text-indent:25px">一、HC41X消聲止回閥產(chǎn)品概述　　HC41X消聲止回閥適用于給排水管道，閥瓣采用進(jìn)口兩端中心軸導(dǎo)向，啟閉靈活，可水平安裝或垂直安裝。閥瓣采用彈簧加載，北京直銷(xiāo)止回閥型號(hào)及規(guī)格，其快速關(guān)閉能有效的消除水錘，密封性能好，關(guān)閉無(wú)噪聲。它具有體積小、重量輕、流體阻力小，耐疲勞、壽命長(zhǎng)等優(yōu)點(diǎn)。消聲止回閥是指依靠介質(zhì)本身流動(dòng)而自動(dòng)開(kāi)、閉閥瓣，用來(lái)防止介質(zhì)倒流的閥門(mén)，又稱(chēng)逆止閥、單向閥、逆流閥、和背壓閥。止回閥屬于一種自動(dòng)閥門(mén)，北京直銷(xiāo)止回閥型號(hào)及規(guī)格，其主要作用是防止介質(zhì)倒流、防止泵及驅(qū)動(dòng)電動(dòng)機(jī)反轉(zhuǎn)，以及容器介質(zhì)的泄放。止回閥還可用于給其中的壓力可能升至超過(guò)系統(tǒng)壓的輔助系統(tǒng)提供補(bǔ)給的管路上。止回閥主要可分為旋啟式止回閥（依重心旋轉(zhuǎn)）與升降式止回閥（沿軸線移動(dòng)），北京直銷(xiāo)止回閥型號(hào)及規(guī)格。　　這種類(lèi)型的閥門(mén)的作用是只允許介質(zhì)向一個(gè)方向流動(dòng)，而且阻止方向流動(dòng)。通常這種閥門(mén)是自動(dòng)工作的，在一個(gè)方向流動(dòng)的流體壓力作用下，閥瓣打開(kāi)；流體反方向流動(dòng)時(shí)，由流體壓力和閥瓣的自重合閥瓣作用于閥座，從而切斷流動(dòng)。不宜用于含有固體顆粒和粘度較大的介質(zhì)。</p><div
