詳細內容：德國萊克LIK品牌-進口氣動球閥一種轉角為90°的旋轉類控制閥。它由氣動活塞式執(zhí)行機構和O型球閥組成，閥芯采用圓柱形通孔球體。QJ(D/S)R型為軟密封球閥、QJ(D/S)RY型為硬密封球閥。 該產品以壓縮空氣為動力源，接受集散控制系統(tǒng)(DCS)，可編程控制器(PLC)等開關信號，通過電磁閥可實現對閥門快速位式控制。 該產品采用直通型鑄造閥體，球面經特殊工藝加工和硬化處理，使其表面光滑耐磨，具有壽命長、結構緊湊、動作可靠、流通能力大、流阻系數小、安裝方便及良好的切斷性能等特點。產品廣泛應用于造紙、石化、冶金、航天、食品、醫(yī)藥、水處理等行業(yè)，特別適用于高黏度和含有纖維介質的工藝控制。 氣動活塞式執(zhí)行機構可分為單作用和雙作用兩種。雙作用使用在失電或失氣時，閥門處于失電或失氣時的位置，以確保繼續(xù)生產。單作用在失電或失氣時，閥門處于原始極限位置(全開或全閉)，以確保生產過程處于安全位置。 QJ (D / S) R-type O-intensive small pneumatic valve one kind of cut off the corner of 90 ° rotation of the controlled valve. It consists of pneumatic piston actuator and the composition of O-type ball valve, valve core sphere using cylindrical hole. QJ (D / S) R-type for soft seated ball valve, QJ (D / S) RY-type of seal valve. The product is compressed air as power source, accept the distributed control system (DCS), programmable logic controller (PLC) such as switching signals, can be realized through the solenoid valve control valve fast bits. The product is through casting body, spherical processed by special technology and hardened, making it a smooth surface wear, with a long life, compact structure, reliability, flow capacity, flow resistance coefficient is small, easy to install and good cut-off performance characteristics. Products are widely used in papermaking, petrochemical, metallurgy, aerospace, food, medicine, water treatment and other industries, particularly for high viscosity and contain fiber media process control. Pneumatic piston actuators can be divided into single and double acting two. Dual role in the loss of power or loss of use of gas when the valve is out of power or loss of gas when the position to ensure continued production. Single in the loss of power or loss of gas when the valve is in the original extreme position (open or closed) to ensure that the production process in a secure location 主要零件材質表 Form of Major Parts Materials 序號 No 零件名稱 Accessory name 材質 C P R 1 右閥體 Bonnet WCB ZG1Cr18Ni9Ti ZG1Cr18Ni12Mo2Ti 2 螺母 Nut 35 1Cr18Ni9Ti 1Cr18Ni9Ti 3 墊片 Gasket PTFE PTFE PTFE 4 螺柱 Stud 35 1Cr18Ni9Ti 1Cr18Ni9Ti 5 閥體 Body WCB ZG1Cr18Ni9Ti ZG1Cr18Ni12Mo2Ti 6 閥座 Seat PTFE PTFE PTFE 7 球體 Ball 1Cr18Ni9Ti 1Cr18Ni9Ti lCr18Ni12Mo2Ti 8 閥桿 Stem 1Cr13 1Cr18Ni9Ti lCr18Ni12Mo2Ti 9 墊片 Gasket PTFE PTFE PTFE 10 填料 Packing PTFE PTFE PTFE 11 襯套 Bushing PTFE PTFE PTFE 12 壓蓋 Gland WCB ZG1Cr18Ni9Ti ZG1Cr18Ni12Mo2Ti 13 螺栓 Bolt 35 1Cr18Ni9Ti 1Cr18Ni9Ti 14 螺栓 Bolt 35 1Cr18Ni9Ti 1Cr18Ni9Ti 15 連接支架 Connecting Yoke 1Cr18Ni9Ti 1Cr18Ni9Ti 1Cr18Ni9Ti 16 螺栓 Bolt 35 1Cr18Ni9Ti 1Cr18Ni9Ti 17 連接套 Connecting Set 35 1Cr18Ni9Ti 1Cr18Ni9Ti 18 氣動裝置 Pneumatic Device 19 位置指示器 Location Indicator *主要零部件及密封圈的材質亦可根據實際工況條件或用戶特殊要求設計選用。 Note: The main spare parts and sealing-ring materials of ball valve series can be designed for Options as per real working conditions and users special reauirements. 二、主要技術參數和技術指標Main technical parameters and technical indicators 1、主要技術參數Main technical parameters 公稱通徑mm 15 20 25 32 40 50 65 80 100 125 150 200 250 300 350 400 額定流量系數Kv 21 38 72 112 170 275 380 512 941 1450 2220 3590 5130 7360 8750 11800 公稱壓力MPa 1.6、2.5、4.0．、6.4 額定行程 Rated travel 90° 固有流量特性 Inherent flow characteristic 快開特性Quick-opening feature 閥體材質 Body material ZG230~450、ZG1Cr18Ni9Ti、ZG1Cr18Ni12Mo2Ti 閥座材質 Seat Material 軟密封：PTFE、PPL;硬密封：不銹鋼 Soft Seal: PTFE, PPL; seal: stainless steel 閥芯材質 Spool material ZG230~450、ZG1Cr18Ni9Ti、ZG1Cr18Ni12Mo2Ti 介質溫度℃ -40~+80、-40~+350 氣源壓力Mpa 0.4~0.6 電磁閥 Solenoid valve 電源 Power supply 220V AC、24V DC 防爆等級 Explosion levels 普通型、防爆型dIIBT4(dIICT4)、本安型 Common type, explosion-proof dIIBT4 (dIICT4), intrinsically safe 連接形式 Connection form GB9113—2000(JB/T79-94) 泄漏量Leakage 軟密封：VI級；硬密封：IV級 Soft sealing: VI grade; seal: IV level 執(zhí)行機構接口 Actuator interfaces 1/8”G NAMUR1/4”G 注：1.DN200及以下浮動球閥；DN250及以上固定球閥 Note: 1.DN200 and below the floating ball; DN250 and above the fixed ball valve 2、執(zhí)行機構扭轉及動作時間Action to reverse the actuator and the time 執(zhí)行機構型號AGT 63*90 75*90 83*90 92*90 110*90 118*90 127*90 160*90 210*90 254*90 255*90 扭矩N.m 400KPa 23.2 40.0. 56.0 77.6 112.8 168.0 220.0 440.0 948.0 1740.0 2172.0 500KPa 29.0 50.0 70.0 97.0 141.0 210.0 275.0 550.0 1185.0 2175.0 2715.0 動作時間(S) 0.241 0.333 0.429 0.444 0.461 0.60 0.857 1.62 3.33 6.00 7.50 注：1、雙作用執(zhí)行機構在75%負載情況下的動作時間 2、縮短動作時間可允許非標配置 Note: 1, double-acting actuators at 75% load case, the action time of 2 to shorten the operating time to allow non-standard configuration 三、允許壓差Permissible differential pressure 1、雙作用執(zhí)行機構 PN1.6閥體 Double-acting valve actuator PN1.6 單位：MPa 公稱通徑(mm) 15 20 25 32 40 50 65 80 100 125 150 200 250 300 執(zhí)行機構 Executive body 氣源KPaG 允許壓差Permissible differential pressure AGT63 400 1.6 1.6 1.09 500 1.6 1.6 1.6 AGT75 400 1.6 500 1.6 AGT83 400 1.6 1.6 0.97 500 1.6 1.6 1.95 AGT110 400 1.6 1.6 1.6 500 1.6 1.6 1.6 AGT118 400 1.6 1.9 0.63 500 1.6 1.6 1.24 AGT160 400 1.6 1.6 0.29 500 1.6 1.6 0.65 AGT210 400 1.6 1.25 0.65 500 1.6 1.58 0.93 AGT254 400 1.6 1.51 0.62 0.51 500 1.6 1.9 0.78 0.68 AGT255 400 1.6 1.26 1.43 0.8 500 1.6 1.26 1.84 1.05 2、單作用執(zhí)行機構 PN1.6閥體Single-acting valve actuator PN1.6 公稱通徑(mm) 15 20 25 32 40 50 65 80 100 125 150 200 250 300 執(zhí)行機構 Executive body 氣源KPaG 允許壓差Permissible differential pressure AGT75 400 1.6 1.6 500 1.6 1.6 AGT83 400 1.6 1.6 0.75 500 1.6 1.6 1.6 AGT110 400 1.6 500 1.6 AGT118 400 1.6 1.04 500 1.6 1.6 AGT160 400 1.6 1.6 1.6 0.16 500 1.6 1.6 1.6 1.08 AGT210 400 1.6 1.6 1.02 500 1.6 1.6 1.6 AGT254 400 1.6 1.6 1.32 0.26 500 1.6 1.6 1.6 1.1 AGT255 400 1.6 1.7 1.01 0.22 0.28 0.1 500 1.6 1.6 1.71 0.71 0.6 0.3 訂貨須知Ordering Information 1、產品型號 2、公稱通徑 3、公稱壓力 4、閥體和閥內組件材料(介質性能) 5、介質溫度 6、雙作用或單作用(單作用請注明氣開式或氣關式) 1, Model 2, DN 3, PN 4, the valve body and internal components of materials (dielectric properties) 5, 6 medium temperature, double or single acting (one
