style="font-size:16px;">固定球閥的特點(diǎn)1、雙阻塞與排放功能：固定球閥采用彈簧預(yù)緊浮動閥座，無論閥門處于全開或全關(guān)狀態(tài)時，上下游側(cè)的閥座使流體阻斷，閥體中腔滯留物通過排放閥排泄。2、自動泄壓功能：閥門體腔停留介質(zhì)溫度升高而引起異常升壓時，不需通過安全閥，而*靠閥座功能就可自動泄壓，這對保證閥門在輸送液體介質(zhì)時的安全性非常重要。3、防火安全結(jié)構(gòu)：閥門都具備防火安全功能，其設(shè)計(jì)、制造均遵循API607和API6FA規(guī)范要求。固定球閥的優(yōu)勢1、密封緊急注脂救護(hù)：由于介質(zhì)中的異物或火災(zāi)造成閥座密封意外失效，注脂閥提供了與注脂的快速連接，方便快捷地將密封脂注入到閥座密封部位，緩解泄漏。2、可靠的閥桿密封和低操作力矩：除了設(shè)置標(biāo)準(zhǔn)密封套圈外，填料壓蓋上也設(shè)置了“O”型密封圈，雙重密封保證了閥桿密封的可靠性；增設(shè)的石墨填料和密封脂注入使火災(zāi)后的閥桿泄漏降至比較低。閥桿滑動軸承和止推軸承使閥門操作輕便。3、全通徑或縮徑：可根據(jù)需要選用全通徑或縮徑結(jié)構(gòu)。</span><span

style="font-size:16px;">球閥的維修1、只有卸除球閥前后的壓力，才能對球閥進(jìn)行拆卸分解操作。2、在對球閥的分解與再裝配過程，需要對有密封性零部件的保護(hù)，特別是非金屬零部件，像O型圈等部件比較好使用**的工具。3、球閥閥體重新裝配時螺栓必須對稱、逐步、均勻地?cái)Q緊。4、清洗劑應(yīng)與球閥中的橡膠件、塑料件、金屬件及工作介質(zhì)(例如燃?xì)?等均相容。工作介質(zhì)為燃?xì)鈺r，可用汽油(GB484-89)清洗金屬零件。非金屬零件用純凈水或酒精清洗。5、分解下來的單個零件可以用浸洗方式清洗。尚留有未分解下來的非金屬件的金屬件可采用干轉(zhuǎn)子泵凈的細(xì)潔的浸漬有清洗劑的綢布(為避免纖維脫落粘附在零件上)擦洗。清洗時須去除一切粘附在壁面上的油脂、污垢、積膠、灰塵等。6、非金屬零件清洗后應(yīng)立即從清洗劑中取出，不得長時間浸泡。7、清洗后需待被洗壁面清洗劑揮發(fā)后(可用未浸清洗劑的綢布擦)進(jìn)行裝配，但不得長時間擱置，否則會生銹、被灰塵污染。8、新零件在裝配前也需清洗干凈。9、使用潤滑脂潤滑。潤滑脂應(yīng)與球閥金屬材料、橡膠件、塑料件及工作介質(zhì)均相容。工作介質(zhì)為燃?xì)鈺r，可用例如特221潤滑脂。在密封件安裝槽的表面上涂一薄層潤滑脂，在橡膠密封</span><span style="font-size:16px;">件上涂一薄層潤滑脂。</span> </p><p> <span style="font-size:16px;">球閥適用場合由于球閥通常用橡膠、尼龍和聚四氟乙烯作為閥座密封圈材料，因此它的使用溫度受到閥座密封圈材料的限制。球閥的截止作用是靠金屬球體在介質(zhì)的作用下，于塑料閥座之間相互壓緊來完成的（浮動球球閥）。閥座密封圈在一定的接觸壓力作用下，局部地區(qū)發(fā)生彈塑變形。這一變形可以補(bǔ)償球體的制造精度和表面粗糙度，保證球閥的密封性能。又由于球閥的閥座密封圈通常采用塑料制成，故在選擇球閥的結(jié)構(gòu)和性能上，要考慮球閥的耐火和防火，特別是在石油、化工、冶金等部門，在易燃、易爆介質(zhì)的設(shè)備和管路系統(tǒng)中使用球閥，更應(yīng)注意耐火和防火。通常，在雙位調(diào)節(jié)、密封性能嚴(yán)格、泥漿、磨損、縮口通道、啟閉動作迅速（1/4轉(zhuǎn)啟閉）、高壓截止（壓差大）、低噪聲、有氣穴和氣化現(xiàn)象、向大</span><span

alt="西寧球閥多少錢,球閥" src="https://tyunfile.71360.com/UploadFile/gscyhwz/637318945336777343/4499907.png"></div><p> <span style="font-size:16px;">球閥密封的現(xiàn)狀與分析鑄石球閥是在灰渣管路中比較理想的啟閉裝置，其上密封好壞直接影響閥門的質(zhì)量和使用壽命。過去采用O形橡膠密封結(jié)構(gòu)形式，即在軸上加工出的環(huán)形槽內(nèi)放入O形密封圈，然后將其裝配進(jìn)套類零件上加工出的孔內(nèi)，形成軸與孔的密封，這種結(jié)構(gòu)的密封性能取決于設(shè)計(jì)時的過盈量，即O形密封圈的壓縮量和孔、軸零件的加工精度。過盈量太小，密封性能差，過盈量太大，裝配時容易擠壞O形密封圈，使密封失效。該密封結(jié)構(gòu)簡單，裝配容易。但若軸、孔的加工精度不高或難以提高加工精度時，除基本的密封性能難以保證或難以進(jìn)一步提高精度時，其主要的缺點(diǎn)在于密封材料，這種密封結(jié)構(gòu)在氣缸、液缸中還是很適用的，在灰渣水中所使用鑄石球閥上密封就很難保證其密封性能了。原因在于球閥的開關(guān)屬于部分回轉(zhuǎn)型的，經(jīng)常需90°開關(guān)。由于閥桿與閥體之間為動配合，有一定間隙，閥門在開關(guān)時介質(zhì)作用在球體上的巨大推力，必然使閥桿產(chǎn)生一定傾斜，閥桿的力偏向的一邊，</span><span style="font-size:16px;">那一邊就磨損嚴(yán)重，而且灰渣水中含有大量懸浮物沖蝕著密封圈。引起閥桿部位O形密封圈壽命周期短，泄露現(xiàn)象經(jīng)常發(fā)生，對現(xiàn)場環(huán)境也造成一定影響，因此決定對密封結(jié)構(gòu)形式及材料進(jìn)行改進(jìn)。</span>
