工作原理: 工作原理: H76H、H76X對(duì)夾蝶式止回閥閥瓣動(dòng)作空間小,閥門的結(jié)果長(zhǎng)度可縮小。閥瓣只在接近流體中心部位動(dòng)作,閥門的高度可以降低。因此,閥門的結(jié)構(gòu)緊湊。閥瓣為翼型。閥瓣的開度大。當(dāng)流體流動(dòng)時(shí),由于偏心,閥瓣的回轉(zhuǎn)半徑小,閥瓣能夠迅速開啟。并在zui后階段,重錘偏過(guò)中心線,幫助閥瓣達(dá)到全開位置,而且能夠起到穩(wěn)定作用,不受水流動(dòng)的影響,使行動(dòng)阻力小。因此流體正流時(shí),流體壓力損失小。 產(chǎn)品特點(diǎn): 1、體積小、重量輕、結(jié)構(gòu)緊湊、便于維護(hù)。 2、閥板采用對(duì)偶板上加兩個(gè)扭力彈簧的設(shè)計(jì),可使閥板自行速閉。 3、因速閉作用,可防止介質(zhì)倒流,消除水錘作用強(qiáng)。 4、閥體結(jié)構(gòu)長(zhǎng)度尺寸小、剛性好。 5、安裝方便,可在水平、垂直兩個(gè)方向的管路上安裝。 6、達(dá)到*密封,水壓試驗(yàn)泄漏量為零。 7、使用性能安全可靠,抗干擾性好。 產(chǎn)品尺寸: H76對(duì)夾雙瓣旋啟式止回閥(美標(biāo)) H76 double discs wafer type swing check valve (ANSI standard) 主要尺寸及重量 Main dimensions and weigth 壓力級(jí) Pressure rating | 口徑 DN | 尺寸(mm) Dimension | 重量 (kg) Weight | 配管法蘭(供參考) Flange(as referenced) | NPS | DN | L | D | D3 | D2 | 螺栓孔中 心圓直徑D1 The diameter of the bore central circle of bolt | 螺栓 數(shù)量 Quantity of the bolt | 累栓直徑 Diameter of the bolt | 螺栓長(zhǎng)度L1 Length of the bolt | in | mm | RF | RJ | Class 150 PN2.0MPa | 2 | 50 | 60 | 103 | 56 | 51 | 2 | 120.5 | 4 | 5/8 | M16 | 140 | 155 | 2 1/2 | 65 | 67 | 122 | 73 | 65 | 3 | 139.5 | 4 | 5/8 | M16 | 150 | 165 | 3 | 80 | 73 | 135 | 88 | 80 | 4 | 152.5 | 4 | 5/8 | M16 | 160 | 175 | 4 | 100 | 73 | 173 | 108 | 102 | 6 | 190.5 | 8 | 5/8 | M16 | 170 | 185 | 5 | 125 | 86 | 195 | 132 | 127 | 8 | 216.5 | 8 | 3/4 | M20 | 190 | 205 | 6 | 150 | 98 | 220 | 160 | 152 | 13 | 241.5 | 8 | 3/4 | M20 | 205 | 220 | 8 | 200 | 127 | 277 | 210 | 203 | 25 | 298.5 | 8 | 3/4 | M20 | 240 | 255 | 10 | 250 | 146 | 337 | 366 | 254 | 39 | 362.0 | 12 | 7/8 | M24 | 270 | 285 | 12 | 300 | 181 | 407 | 310 | 305 | 54 | 432.0 | 12 | 7/8 | M24 | 310 | 325 | 14 | 350 | 184 | 448 | 355 | 350 | 80 | 476.0 | 12 | 1 | M27 | 325 | 340 | 16 | 400 | 191 | 512 | 405 | 400 | 117 | 540.0 | 16 | 1 | M27 | 340 | 355 | 18 | 450 | 203 | 547 | 455 | 450 | 138 | 578.0 | 16 | 1 1/8 | M30 | 365 | 380 | 20 | 500 | 219 | 604 | 505 | 500 | 163 | 635.0 | 20 | 1 1/8 | M30 | 385 | 400 | 24 | 600 | 222 | 715 | 605 | 600 | 331 | 749.5 | 20 | 1 1/4 | M33 | 405 | 420 | 28 | 700 | 305 | 773 | 700 | 700 | 380 | 795.5 | 40 | 3/4 | M20 | 455 | - | 30 | 750 | 305 | 824 | 750 | 746 | 425 | 846.0 | 44 | 3/4 | M20 | 455 | - | 32 | 800 | 305 | 878 | 800 | 796 | 560 | 900.0 | 48 | 3/4 | M20 | 460 | - | 36 | 900 | 368 | 983 | 910 | 898 | 640 | 1009.5 | 44 | 7/8 | M24 | 540 | - | 40 | 1000 | 432 | 1142 | 1055 | 1055 | 960 | 1171.5 | 48 | 1 | M27 | 625 | - | 48 | 1200 | 524 | 1302 | 1205 | 1200 | 1400 | 1335.0 | 44 | 1 1/8 | M30 | 740 | - | Class 300 PN5.0MPa | 2 | 50 | 60 | 110 | 58 | 51 | 3 | 127.0 | 8 | 5/8 | M16 | 155 | 175 | 2 1/2 | 65 | 67 | 128 | 73 | 65 | 4 | 149.0 | 8 | 3/4 | M20 | 175 | 195 | 3 | 80 | 73 | 147 | 88 | 80 | 6 | 168.5 | 8 | 3/4 | M20 | 190 | 210 | 4 | 100 | 73 | 179 | 108 | 102 | 8 | 200.0 | 8 | 3/4 | M20 | 195 | 215 | 5 | 125 | 86 | 214 | 132 | 127 | 15 | 235.0 | 8 | 3/4 | M20 | 215 | 235 | 6 | 150 | 98 | 249 | 160 | 152 | 18 | 270.0 | 12 | 3/4 | M20 | 230 | 250 | 8 | 200 | 127 | 305 | 210 | 203 | 31 | 330.0 | 12 | 7/8 | M24 | 280 | 300 | 10 | 250 | 146 | 359 | 266 | 254 | 51 | 387.5 | 16 | 1 | M27 | 315 | 335 | 12 | 300 | 181 | 420 | 310 | 305 | 77 | 451.0 | 16 | 1 1/8 | M30 | 365 | 385 | 14 | 350 | 222 | 483 | 355 | 350 | 117 | 414.5 | 20 | 1 1/8 | M30 | 410 | 430 | 16 | 400 | 232 | 537 | 405 | 400 | 190 | 571.5 | 20 | 1 1/4 | M33 | 435 | 455 | 18 | 450 | 264 | 594 | 455 | 450 | 200 | 628.5 | 24 | 1 1/4 | M33 | 475 | 495 | 20 | 500 | 292 | 652 | 505 | 200 | 265 | 686.0 | 24 | 1 1/4 | M33 | 510 | 535 | 24 | 600 | 318 | 772 | 608 | 600 | 410 | 813.0 | 24 | 1 1/2 | M33 | 560 | 560 |
