style="text-indent:25px">氣動(dòng)球閥流體阻力小，球閥是所有閥類中流體阻力較小的一種，即使是縮徑球閥，其流體阻力也相當(dāng)小。開關(guān)迅速、方便，只要閥桿轉(zhuǎn)動(dòng)90°，球閥就完成了全開或全關(guān)動(dòng)作，很容易實(shí)現(xiàn)快速啟閉。密封性能好。球閥閥座密封圈一般采用聚四氟乙烯等彈性材料制造，易于保證密封，而且球閥的密封力隨著介質(zhì)壓力的增加而增大。閥桿密封可靠。球閥啟閉時(shí)閥桿只作旋轉(zhuǎn)運(yùn)動(dòng)，因此閥桿的填料密封不易被破壞，而且閥桿倒密封的密封力隨著介質(zhì)壓力的增加而增大。球閥的啟閉只做90°轉(zhuǎn)動(dòng)，故容易實(shí)現(xiàn)自動(dòng)化控制和遠(yuǎn)距離控制，球閥可配置氣動(dòng)裝置、電動(dòng)裝置、液動(dòng)裝置、氣液聯(lián)動(dòng)裝置或電液聯(lián)動(dòng)裝置。</p><p style="text-indent:25px">氣動(dòng)閥門安裝好以后，對(duì)氣動(dòng)閥門應(yīng)進(jìn)行試驗(yàn)，給氣動(dòng)執(zhí)行器加壓至額定值，壓力為0.4~0.7mpa，對(duì)氣動(dòng)球閥進(jìn)行開關(guān)試驗(yàn)，觀察閥門的開閉情況。應(yīng)轉(zhuǎn)動(dòng)靈活無卡阻現(xiàn)象。在開關(guān)如有卡阻現(xiàn)象可增高氣壓，反復(fù)開關(guān)使閥門調(diào)到開關(guān)靈活即可。安裝調(diào)試開關(guān)型氣動(dòng)閥時(shí)，先用手動(dòng)裝置進(jìn)行(電磁閥上的手動(dòng)按鈕)調(diào)試、動(dòng)作正常后在通電調(diào)試。氣動(dòng)閥應(yīng)定期進(jìn)行維護(hù)保養(yǎng)閥桿轉(zhuǎn)動(dòng)處，應(yīng)三個(gè)月加油(機(jī)油)一次。定期對(duì)氣動(dòng)執(zhí)行單元和配合使用的空氣過濾器進(jìn)行放水、排污。正常的情況下六個(gè)月檢查一次，每年檢修一次。氣動(dòng)閥門型號(hào)有那些呢！</p><div

style="text-indent:25px">氣動(dòng)球閥（又稱兩位閥或開關(guān)閥）可以分為氣開閥與氣關(guān)閥。顧名思義，氣開閥是指用儀表空氣向執(zhí)行機(jī)構(gòu)內(nèi)充壓時(shí)，閥門開啟；當(dāng)執(zhí)行機(jī)構(gòu)將其內(nèi)的儀表空氣卸掉時(shí)則閥門關(guān)閉。氣關(guān)閥則反之。氣動(dòng)球閥之所以有這兩種開啟方式，是因?yàn)楣に囅到y(tǒng)有時(shí)會(huì)發(fā)生氣源故障斷掉的情況，此時(shí)根據(jù)工藝流程的需要，有的閥要開（如切斷閥），有的閥要關(guān)（如放空閥），這樣設(shè)計(jì)人員就在流程設(shè)計(jì)時(shí)根據(jù)需要而采用氣開閥或氣關(guān)閥。氣動(dòng)球閥只需要用氣旋轉(zhuǎn)度的操作和很小的轉(zhuǎn)動(dòng)力矩就能關(guān)閉緊密。完全對(duì)等的閥體內(nèi)腔為介質(zhì)供給了阻力很小、直通的流道。通常以為球閥適合直接做開閉運(yùn)用，但近期的開展已將球閥規(guī)劃成使它具有節(jié)流和控制流量之用。氣動(dòng)球閥的首要特點(diǎn)是自身構(gòu)造緊湊，易于操作和修理，適用于水、溶劑、酸和天然氣等通常作業(yè)介質(zhì)，并且還適用于作業(yè)條件惡劣的介質(zhì)，如氧氣、過氧化氫、甲烷和乙烯等。真空氣動(dòng)閥門用途是什么?上海氣動(dòng)閥蝶閥批發(fā)</p><p
