style="text-indent:25px">一、HC41X消聲止回閥產(chǎn)品概述其中內(nèi)螺紋止回閥,蝶式止回閥就屬于這種類型的閥門，它包括旋啟式止回閥和升降式止回閥。正泉閥門旋啟式止回閥有一介鉸鏈機(jī)構(gòu)，還有一個(gè)像門一樣的閥瓣自由地靠在傾斜的閥座表面上。為了確保閥瓣每次都能到達(dá)閥座面的合適位置，閥瓣設(shè)計(jì)在鉸鏈機(jī)構(gòu)，以便閥瓣具有足夠有旋啟空間，并使閥瓣真正的、充分的與閥座接觸。閥瓣可以全部用金屬制成，也可以在金屬上鑲嵌皮革、橡膠、或者采用合成覆蓋面，這取決于使用性能的要求。旋啟式止回閥在完全打開(kāi)的狀況***體壓力幾乎不受阻礙，因此通過(guò)閥門的壓力降相對(duì)較小。升降式止回閥的閥瓣座落位于閥體上閥座密封面上。此閥門除了閥瓣可以自由地升降之外，其余部分如同截止閥一樣，流體壓力使閥瓣從閥座密封面上抬起，介質(zhì)回流導(dǎo)致閥瓣回落到閥座上，并切斷流動(dòng)。根據(jù)使用條件，閥瓣可以是全金屬結(jié)構(gòu)，也可以是在閥瓣架上鑲嵌橡膠墊或橡膠環(huán)的形式。像截止閥一樣，流體通過(guò)升降式止回閥的通道也是狹窄的，因此通過(guò)升降式止回閥的壓力降比旋啟式止回閥大些，而且旋啟式止回閥的流量受到的限制很少。本類閥門在管道中一般應(yīng)當(dāng)水平安裝。安徽止回閥種類</p><div

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，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，又稱逆止閥、單向閥、逆流閥、和背壓閥。止回閥屬于一種自動(dòng)閥門，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)）。　　這種類型的閥門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><p style="text-indent:25px">消聲止回閥的作用及結(jié)構(gòu)原理: 消聲止回閥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)。　　消聲止回閥作用原理和結(jié)構(gòu)說(shuō)明：　　本閥門在使用過(guò)程中，介質(zhì)按圖示箭頭方向流動(dòng)。　　1、當(dāng)介質(zhì)按規(guī)定方向流動(dòng)時(shí)，閥瓣受介質(zhì)力的作用，被開(kāi)啟;介質(zhì)逆流時(shí)，因閥瓣自重和閥瓣受介質(zhì)反向力的作用，使閥瓣與閥座的密封面密合而關(guān)閉，達(dá)到阻止介質(zhì)逆流的目的。　　2、閥體及閥瓣的密封面采用不銹鋼堆焊。　　3、本閥門的結(jié)構(gòu)長(zhǎng)度按GB12221-1989的規(guī)定，法蘭連接尺寸按JB/T79-1994的規(guī)定。　　其中內(nèi)螺紋止回閥,蝶式止回閥就屬于這種類型的閥門，它包括旋啟式止回閥和升降式止回閥。旋啟式止回閥有一介鉸鏈機(jī)構(gòu)，還有一個(gè)像門一樣的閥瓣自由地靠在傾斜的閥座表面上。為了確保閥瓣每次都能到達(dá)閥座面的合適位置，閥瓣設(shè)計(jì)在鉸鏈機(jī)構(gòu)，以便閥瓣具有足夠有旋啟空間，并使閥瓣真正的、完全的與閥座接觸。</p><div
