八金閥門生產(chǎn)作業(yè)流程：
確認(rèn)訂單后，由設(shè)計(jì)開發(fā)中心提供產(chǎn)品的設(shè)計(jì)圖樣，外購(gòu)明細(xì)/機(jī)械加工程序等技術(shù)文件，通過內(nèi)部網(wǎng)絡(luò)傳輸?shù)礁飨嚓P(guān)部門，生產(chǎn)部門根據(jù)技術(shù)要求和銷售訂單組織生產(chǎn)。毛坯零件進(jìn)廠后，庫(kù)管人員根據(jù)生產(chǎn)計(jì)劃將配件等送往各加工/裝配場(chǎng)地。他們幾乎所有產(chǎn)品零部件都是在數(shù)控設(shè)備上完成對(duì)，加工精度和效率非常精準(zhǔn)。員工在數(shù)控加工設(shè)備的操作臺(tái)上可調(diào)閱零件加工圖和零件加工程序，只需按加工工藝要求將工件裝夾到數(shù)控設(shè)備上，啟動(dòng)加工程序，就可以自動(dòng)完成車/鉆/銑/鏜等加工工序。當(dāng)一臺(tái)設(shè)備的加工程序啟動(dòng)后，再去裝夾另外一臺(tái)，同時(shí)在設(shè)備操作屏幕上可以監(jiān)控其他設(shè)備的加工情況，直至整個(gè)零件加工完成，經(jīng)檢驗(yàn)合格后送裝配車間。而員工在每個(gè)零件加工完成后，將零件跟蹤卡在自己附近的讀卡機(jī)刷一次，將該零件的狀態(tài)/加工信息反饋到相關(guān)部門，有關(guān)部門即可掌握加工進(jìn)度，統(tǒng)計(jì)工人工作量及進(jìn)行質(zhì)量跟蹤。
對(duì)夾式止回閥適用于公稱壓力PN1.0MPa~42.0MPa、Class150-2500；公稱通徑DN15~1200mm、NPS1/2~48；工作溫度-196~540℃的各種管路上，用于防止介質(zhì)倒流。通過選用不同的材質(zhì)，可適用于水、蒸汽、油品、硝酸、醋酸、強(qiáng)氧化性介質(zhì)及尿素等多種介質(zhì)。
