詳細(xì)介紹

之前介紹JIS日標(biāo)不銹鋼截止閥標(biāo)準(zhǔn)，現(xiàn)在介紹煤化工法蘭球閥選型球閥內(nèi)部是一個(gè)帶孔的鋼球，表面非常光潔，兩邊有聚四氟乙烯的密封件，與球體接觸部分為圓弧面，通過閥體上的螺栓或壓母壓緊產(chǎn)生密封作用，球體的頂部開一個(gè)直槽，用于傳遞手柄的扭力。閥門打開時(shí)，球體上的孔與閥門的軸心線平行，形成一個(gè)通道；閥門關(guān)閉時(shí)，通過手柄將球體旋轉(zhuǎn)90°，將通道阻斷。開關(guān)有手動(dòng)方式和氣動(dòng)方式兩種球閥是用帶有圓形通道的球體作啟閉件，球體隨閥桿轉(zhuǎn)動(dòng)實(shí)現(xiàn)啟閉動(dòng)作的閥門。球閥的啟閉件是一個(gè)有孔的球體，繞垂直于通道的軸線旋轉(zhuǎn)，從而達(dá)到啟閉通道的目的。球閥主要供開啟和關(guān)閉管道和設(shè)備介質(zhì)之用。煤化工球閥快速進(jìn)入黃金時(shí)代 煤化工球閥廣泛應(yīng)用于石油、化肥、鋼鐵、制藥、化工高層建筑、紡織等領(lǐng)域。 煤化工球閥是靠旋轉(zhuǎn)閥戀來使閥門暢通或閉塞。

煤化工法蘭球閥選型球閥主要優(yōu)點(diǎn)如下：

1、適用于經(jīng)常操作，啟閉迅速、輕便。

2、流體阻力小。

3、結(jié)構(gòu)簡(jiǎn)單，相對(duì)體積小，重量輕，便于維修。

4、密封性能好

5、不受安裝方向的限制，介質(zhì)的流向可任意。

6、無振動(dòng)，噪聲小。

煤化工法蘭球閥選型球閥的分類：

上海申弘閥門有限公司主營閥門有：截止閥,電動(dòng)截止閥球閥按結(jié)構(gòu)形式可分為：浮動(dòng)球閥、固定球閥、彈性球閥和油封球閥；按通道可分為直能式、角式和三通式等，三通式又可分為T形和L形兩種。按連接方工可分為螺紋式連接、法蘭連接和焊接式三種。

球閥安裝與維護(hù)應(yīng)注意以下事項(xiàng)：

1、要留有閥柄旋轉(zhuǎn)的位置

2、不能用作節(jié)流。

3、帶傳動(dòng)機(jī)構(gòu)的球閥應(yīng)直立安裝。

QB/T1199-1991浮球閥　

球閥開關(guān)輕便，體積小，可以做成很大口徑，密封可靠，結(jié)構(gòu) 簡(jiǎn)單，維修方便，密封面與球面常在閉合狀態(tài)，不易被介質(zhì)沖蝕，在各行業(yè)得到廣泛的應(yīng)用。球閥和旋塞閥是同屬一個(gè)類型的閥門，只有它的關(guān)閉件是個(gè)球體，球體繞閥體中心線作旋轉(zhuǎn)來達(dá)到開啟、關(guān)閉的一種閥門。煤化工球閥的球體是浮動(dòng)的，在介質(zhì)壓力作用下，球體能產(chǎn)生一定的位移并緊壓在出口端的密封面上，保證出口端密封。如果煤化工球閥閥座發(fā)生泄漏，壓力將直接進(jìn)入閥體內(nèi)部，該壓力作用于閥座密封圈上游密封面的內(nèi)側(cè)，并緊緊擠壓閥座密封圈上部。同時(shí)，這種力將迫使閥座密封圈向閥體靠近擠壓，從而在閥座密封圈和閥體之間形成有效的密封 煤化工球閥的結(jié)構(gòu)簡(jiǎn)單，密封性好，但球體承受工作介質(zhì)的載荷全部傳給了出口密封圈，因此要考慮密封圈材料能否經(jīng)受得住球體介質(zhì)的工作載荷。這種結(jié)構(gòu)，廣泛用于中低壓球閥。煤化工球閥的球體是固定的，受壓后不產(chǎn)生移動(dòng)，帶有浮動(dòng)閥座，受介質(zhì)壓力后，閥座產(chǎn)生移動(dòng)，使密封圈緊壓在球體上，以保證密封。

煤化工球閥通常在與球體的上、下軸上裝有軸承，操作扭距小，適用于高壓和大口徑的閥門。為了減少球閥的操作扭矩和增加密封的可靠程度，近年來又出現(xiàn)了油封球閥，既在密封面間壓注特制的潤(rùn)滑油，以形成一層油膜，即增強(qiáng)了密封性，又減少了操作扭矩，更適用高壓大口徑的球閥。 煤化工球閥的球體是彈性的。球體和閥座密封圈都采用金屬材料制造，密封比壓很大，依靠介質(zhì)本身的壓力已達(dá)不到密封的要求，必須施加外力。煤化工球閥適用于高溫高壓介質(zhì)。彈性球體是在球體內(nèi)壁的下端開一條彈性槽，而獲得彈性。當(dāng)關(guān)閉通道時(shí)，用煤化工球閥閥桿的楔形頭使球體漲開與閥座壓緊達(dá)到密封。在轉(zhuǎn)動(dòng)球體之前先松開楔形頭，球體隨之恢復(fù)原原形，使球體與閥座之間出現(xiàn)很小的間隙，可以減少密封面的摩擦和操作扭矩。煤化工球閥基本使用固定軸式的球閥。從上游閥座泄漏到閥腔中，當(dāng)閥腔內(nèi)的壓力超出下游管線壓力時(shí)，下游閥座將脫離球體使閥腔的壓力向閥門下游泄放。具有雙活塞效應(yīng)設(shè)計(jì)的管道球閥在正常情況下，壓力作用于閥座密封圈末端的外側(cè)，這種力迫使閥座密封圈向閥體靠近擠壓，從而在閥座密封圈和閥體之間形成密封。與本文相關(guān)的產(chǎn)品有不銹鋼波紋管密封安全閥
