對(duì)夾球閥產(chǎn)品特點(diǎn) 對(duì)夾連接球閥具有結(jié)構(gòu)緊湊、體積小、重量輕、 密封性能好、啟閉靈活、安裝方便等特點(diǎn)。主要適用于石油、化工、冶金、制藥、食品等各類系統(tǒng)中。 而保溫對(duì)夾連接球閥良好的保溫保冷特性既能有效防止管路中粘稠介質(zhì)凝固,又能降低管路中介質(zhì)熱量的損失。 本系列可裝上相應(yīng)的電動(dòng)及氣動(dòng)裝置,以實(shí)現(xiàn)遙控或自動(dòng)控制。 Features The double-clip connected ball valve possess such features as compact structure, smaller volume, lighter ponderance, fine sealing performance,flexible on-off, convenient installation course, etc. The heating double-clip connected ball valve enjoys favorable heat/cold preservation performances which not only effectively prevent the slabby medium in pipelines from solidifying but also reduce the heat loss of the medium in pipelines. The double-clip connected ball valve series could also be applied with the mounted corresponding motor or air operated plant to implement remote control or automatic control. 技術(shù)規(guī)范Technical Specification 結(jié)構(gòu)形式 Structure form | 對(duì)夾式 Double-clip type | 連接法蘭 Connecting flange | ANSI B16.5、JB/T79 | 驅(qū)動(dòng)方式 Driving manner | 手動(dòng)、電動(dòng)、氣動(dòng) Manual,Moton driving,Pneumatil | 試驗(yàn)和檢驗(yàn) Test & Inspection | JB/T9092-99 API 598 | 主要零件材質(zhì)表Form of Major Patrs Materials 序號(hào) NO | 零件名稱 Accessory name | 材 質(zhì) Material | GB | ASTM | 1 | 閥體 Body | CF8 | A351-CF8 | 2 | 密封圈 Sealing Ring | PTFE、PPL | 3 | 球體 Ball | 0Cr18Ni9 | A351-CF8 | 4 | 閥桿 Stem | 0Cr18Ni9 | A276-304 | 5 | 閥座 Seat | 0Cr18Ni9 | A276-304 | 6 | 墊片 Gasket | PTFE、PPL | 7 | 墊片 Gasket | 柔性石墨 不銹鋼 Graphite stainless steel | 8 | 填料 Stuffing | PTFE、PPL | 9 | 壓套 Stufing cover | 0Cr18Ni9 | A351-CF8 | 主要外型及連接尺寸表Main Types and Connecting Dimension 公稱通徑(DN) Nominal diameter | 主 要 尺 寸 (mm)Main dimension | L | D | W | H | ( mm) | ( in) | 1.0MPa | 1.6MPa | 2.5MPa | 150Lb | 10k | 手動(dòng) | 手動(dòng) | 15 | 1/2 | 40 | 53 | 53 | 53 | 47 | 58 | 130 | 80 | 20 | 3/4 | 45 | 63 | 63 | 63 | 57 | 63 | 170 | 80 | 25 | 1 | 50 | 73 | 73 | 73 | 66 | 74 | 170 | 100 | 32 | 11/4″ | 60 | 84 | 84 | 84 | 75 | 84 | 200 | 110 | 40 | 11/2″ | 70 | 94 | 94 | 94 | 85 | 89 | 250 | 120 | 50 | 2 | 80 | 109 | 109 | 109 | 103 | 104 | 250 | 130 | 65 | 21/2″ | 110 | 129 | 129 | 129 | 122 | 124 | 350 | 140 | 80 | 3 | 120 | 144 | 144 | 144 | 135 | 134 | 350 | 150 | 100 | 4 | 140 | 164 | 164 | 170 | 173 | 159 | 240 | 180 | 注:系列閥門主要零部件及密封面的材質(zhì)可根據(jù)實(shí)際工況條件或用戶特殊要求設(shè)計(jì)選用.
