進(jìn)口襯膠止回閥,(德國(guó)奧萊斯閥門品牌)
【進(jìn)口襯膠止回閥】詳細(xì)說(shuō)明：
襯膠旋啟式止回閥只是允許介質(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)的壓力作用下，閥瓣打開，流體反方向流動(dòng)時(shí)有流體壓力和閥瓣的自重，閥瓣作用于閥座，從而切斷流動(dòng)。 旋啟式襯膠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、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。旋啟式襯膠止回閥的閥瓣呈圓盤狀，繞閥座通道的轉(zhuǎn)軸作旋轉(zhuǎn)運(yùn)動(dòng)，因閥內(nèi)通道成流線形，流動(dòng)阻力比升降式止回閥小，適用于低流速和流動(dòng)不常變化的大口徑場(chǎng)合，但不宜用于脈動(dòng)流。
The rubber-lined swing check valve only allows the medium to flow in one direction and prevents the flow in the direction. Usually, the valve operates automatically. Under the pressure of one direction, the valve disc opens. When the fluid flows in the opposite direction, there are fluid pressure and the weight of the valve disc. The valve disc acts on the valve seat to cut off the flow. &# 160; Swing-type rubber-lined check valve belongs to an automatic valve, its main function is to prevent medium backflow, pump and drive motor reversal, and the release of container medium. Check valves can also be used in pipelines to supply auxiliary systems where pressure may rise above system pressure. The disc of the swing-type rubber-lined check valve is disc-shaped and rotates around the rotating axis of the seat passage. Because the passage inside the valve is streamlined, the flow resistance is smaller than that of the lift-type check valve. It is suitable for large caliber situations with low flow rate and unstable flow, but it is not suitable for pulsating flow.
【進(jìn)口襯膠止回閥】結(jié)構(gòu)說(shuō)明：
結(jié)構(gòu)一般與截止閥相似，其閥瓣沿著通道中以線作升降運(yùn)動(dòng)，動(dòng)作可靠，但流體阻力較大，適用于輕小口徑的場(chǎng)合。升降式止回閥可直通式和立式兩種。直通式升降止回閥一般只能安裝在水平管路，而立式升降止回閥一般就安裝在垂直管路?！ ⌒龁⑹街够亻y的閥瓣繞轉(zhuǎn)軸作旋轉(zhuǎn)運(yùn)動(dòng)。其流體阻力一般小于升降式止回閥，它適用于較大口徑的場(chǎng)合。旋啟式止回閥根據(jù)閥瓣的數(shù)目可分為單瓣旋啟式、雙瓣旋啟式及多瓣旋啟式三種。單瓣旋啟式止回閥一般適用于中等口徑的場(chǎng)合。大口徑管路選用單瓣旋啟式止回閥時(shí)，為減少水錘壓力，hao采用能減小水錘壓力的緩閉止回閥。雙瓣旋啟式止回閥適用于大中口徑管路。對(duì)夾雙瓣旋啟式止回閥結(jié)構(gòu)小、重量輕，是一種發(fā)展較快的止回閥；多瓣旋啟式止回閥適用于大口徑管路。
【進(jìn)口襯膠止回閥】特性：
襯膠止回閥屬于對(duì)夾碟型旋啟式類型的止回閥,本產(chǎn)品體積小,流道廣,阻力系數(shù)低,關(guān)閉快的性能特點(diǎn),是造價(jià)低性能*的一種止回閥,廣泛的使用在化工,冶金,煤礦,給水等場(chǎng)合。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)了鉸鏈機(jī)構(gòu),以便閥瓣具有足夠有旋啟空間,并使閥瓣真正的,全面的與閥座接觸。閥瓣可以全部用金屬制成,也可以在金屬外包裹橡膠,這取決于使用性能的要求。對(duì)夾襯膠止回閥在*打開的狀況下,流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
