①溢流閥：溢流閥是一種液壓壓力控制閥，在液壓設(shè)備中主要起定壓溢流、穩(wěn)壓、系統(tǒng)卸荷和安全保護(hù)作用。 ②減壓閥:減壓閥是通過(guò)調(diào)節(jié)，將進(jìn)口壓力減至某一需要的出口壓力，并依靠介質(zhì)本身的能量，使出口壓力自動(dòng)保持穩(wěn)定的閥門。 ③順序閥:順序閥是指在具有二個(gè)以上分支回路的系統(tǒng)中，根據(jù)回路的壓力等來(lái)控制多個(gè)執(zhí)行元件動(dòng)作順序的閥。根據(jù)其功能和裝配結(jié)構(gòu)的不同，可以實(shí)現(xiàn)不同的回路功能，如溢流閥、順序閥、背壓閥、卸荷閥和平衡閥的功能。</p><div style="width:100%;text-align:

style="text-indent:25px">閥門安裝需要注意哪些事項(xiàng)呢? 1、安裝閥門時(shí)需要清潔內(nèi)腔和密封面,連接螺栓是否均勻擰緊,檢查填料是否壓緊。 2、安裝時(shí)的閥門是處于關(guān)閉狀態(tài)。大規(guī)格的閘閥、氣動(dòng)調(diào)節(jié)閥應(yīng)該豎裝，以免因閥芯的自重較大而偏向一方，這樣會(huì)產(chǎn)生泄露情況。 3、閥門應(yīng)按照允許的工作位置安裝,但須注意檢修和操作的方便。 4、截止閥的安裝應(yīng)使介質(zhì)流向與閥體上標(biāo)示的箭頭一致，對(duì)不經(jīng)常啟閉而又需要嚴(yán)格保證在關(guān)閉狀態(tài)下不漏的閥門，可以反裝，以借助介質(zhì)壓力使之緊閉。 5、在擰緊壓緊螺釘時(shí)，閥門應(yīng)處于微開狀態(tài)，以免壓壞閥頂密封面。 6、低溫閥門在定位之前應(yīng)盡量在冷態(tài)下做啟閉試驗(yàn)，要求靈活無(wú)卡殼現(xiàn)象。 7、液體閥應(yīng)配置成閥桿與水平成10°傾斜角，避免液體順著閥桿流出，更嚴(yán)重的是避免產(chǎn)生泄露。 8、嚴(yán)禁在安裝時(shí)把閥桿當(dāng)腳手架攀登。 9、所有閥門就位后，應(yīng)再作一次啟閉，靈活無(wú)卡住現(xiàn)象為合格。 10、閥門安裝之前，要確認(rèn)閥門符合設(shè)計(jì)要求和有關(guān)標(biāo)準(zhǔn)。管道內(nèi)部要清洗，除去鐵屑等雜質(zhì)，防止閥門密封座夾雜異物。 11、高溫閥門安裝時(shí)處于常溫，使用后，溫度升高，螺栓受熱膨脹，間隙加大，所以需要再次擰緊，這個(gè)問(wèn)題需注意，不然容易發(fā)生泄露。</p></p><br /><p>文章來(lái)源地址: http://m.cdcfah.com/cp/314477.html</p></div></div></div></div></div><div id="pjbikri"
