style="text-indent:25px">閥門注脂時(shí)，常忽略壓力問題。在注脂操作時(shí)，注脂壓力有規(guī)律地呈峰谷變化。壓力過低，密封漏或失效，壓力過高，注脂口堵塞、密封內(nèi)脂類硬化或密封圈與閥球、閥板抱死。通常注脂壓力過低時(shí)，注入的潤滑脂多流入閥腔底部，一般發(fā)生在小型閘閥。而注脂壓力過高，一方面檢查注脂嘴，如是脂孔阻塞判明情況進(jìn)行更換；另一方面是脂類硬化，要使用清洗液，反復(fù)軟化失效的密封脂，吐魯番低壓閥門的價(jià)格，并注入新的潤滑脂置換。此外，密封型號和密封材質(zhì)，也影響注脂壓力，不同的密封形式有不同的注脂壓力，一般情況硬密封注脂壓力要高于軟密封。第三、閥門注脂時(shí)，注意閥門在開關(guān)位的問題。球閥維護(hù)保養(yǎng)時(shí)一般都處于開位狀態(tài)，吐魯番低壓閥門的價(jià)格，特殊情況下選擇關(guān)閉保養(yǎng)，吐魯番低壓閥門的價(jià)格。其他閥門也不能一概以開位論處。博樂立臥兩用止回閥廠家。吐魯番低壓閥門的價(jià)格</p><div

一、根據(jù)流量特性選用閥門閥門啟閉件及閥門流道的形狀使閥門具備一定的流量特性。在選擇閥門時(shí)，必須考慮到這一點(diǎn)。1.截?cái)嗪徒油ń橘|(zhì)用閥門通常選擇流阻較小、流道為直通式的閥門。這類閥門有閘閥、截止閥、柱塞閥。向下閉合式閥門，由于流道曲折，流阻比其它閥門高，故較少選用。但是，在允許有較高流阻的場合，也可選用閉合式閥門。2.控制流量用的閥門通常選擇易于調(diào)節(jié)流量的閥門。如調(diào)節(jié)閥、節(jié)流閥、柱塞閥，因?yàn)樗拈y座尺寸與啟閉件的行程之間成正比例關(guān)系。旋轉(zhuǎn)式（如旋塞閥、球閥、蝶閥）和撓曲閥體式（夾管閥、隔膜閥）閥門也可用于節(jié)流控制，但通常*在有限的閥門口徑范圍內(nèi)適用。在多數(shù)情況下，人們通常采用改變截止閥的閥瓣形狀后作節(jié)流用。應(yīng)該指出，用改變閘閥或截止閥的開啟高度來實(shí)現(xiàn)節(jié)流作用是極不合理的。因?yàn)椋苈分薪橘|(zhì)在節(jié)流狀態(tài)***速很高，密封面容易被沖刷磨損，失去切斷密封作用，同理，用節(jié)流閥作為切斷裝置也是不合理的。3.換向分流用閥門根據(jù)換向分流需要，這種閥可有三個(gè)或者更多的通道，適宜于選用旋塞閥和球閥。大部分換向分流用的閥門都選用這類閥門。在某些情況下，其它類型的閥門，用兩只或更多只適當(dāng)?shù)叵嗷ミB接起來?？死斠栏邷亻y門公司博樂閘閥廠家昌吉球型止回閥廠家。</p><div

縮口閘閥阻力系數(shù)大一些。截止閥的阻力系數(shù)比閘閥大得多，一般在4～7之間。Y型截止閥（直流式）阻力系數(shù)**小，在～2之間。鍛鋼截止閥阻力系數(shù)**大，甚至高達(dá)8。止回閥的阻力系數(shù)視結(jié)構(gòu)而定：旋啟式止回閥通常約為～2，其中多瓣旋啟式止回閥的阻力系數(shù)較大；升降式止回閥阻力系數(shù)**大，高達(dá)12。旋塞閥的阻力系數(shù)小，通常約為～。隔膜閥的阻力系數(shù)一般在。蝶閥的阻力系數(shù)小，一般在。球閥的阻力系數(shù)**小，一般在。上述閥門的阻力系數(shù)是閥門全開狀態(tài)下的數(shù)值。閥門通徑的選用，應(yīng)考慮到閥門的加工精度和尺寸偏差，以及其它因素影響。閥門通徑應(yīng)有一定的富裕量，一般為15%。在實(shí)際的工作中，閥門通徑隨工藝管線的通徑而定。六、根據(jù)工況條件和工藝操作綜合確定閥門的結(jié)構(gòu)型式返回頁首1.工藝要求氨對銅有腐蝕作用，不能選用銅材質(zhì)制作的閥門。在介質(zhì)中含有氨的工藝流程中，截止閥的結(jié)構(gòu)與一般閥門不同，其密封面是用巴氏合金制作的。雙流向的管線應(yīng)選用無方向性的閥門。在煉油廠，重質(zhì)油管停止運(yùn)行后，要用蒸汽反向吹掃管線，以防重油凝固堵塞管線，因而不宜采用截止閥。因?yàn)榻橘|(zhì)反向流入時(shí)，容易沖蝕截止閥密封面，應(yīng)選用閘閥為佳。對某些有析晶或含有沉淀物的介質(zhì)。</p><p>
