一、結(jié)構(gòu)及用途 Structure and purpose 該閥用于生活供水和消防供水并聯(lián)供水系統(tǒng)中，正常情況供生活用水，當(dāng)火災(zāi)發(fā)生時(shí)消防用水時(shí)，閥門自動(dòng)關(guān)閉生活用水，確保足夠的消防用水。當(dāng)消防停止用水時(shí)壓力減少，閥門自動(dòng)恢復(fù)生活用水，該閥使系統(tǒng)無須另設(shè)專門的消防單獨(dú)供水管網(wǎng)，大大地節(jié)省了工程建設(shè)成本和日常的用水量。該閥控制靈敏、安全可靠、調(diào)試簡單、使用壽命長。 Used in the living and fire-fighting merged water supply system It supplies living water at normal condition and．in case of a fire，automatically close the living water and open the fire-fighting one to make it surely enough，and then when fire-fighting water stops and the pressure is reduced，resets the living wa-ter automatically．Thus making the system no need to set an individual fire-fighting water supply pipe network and both engineering construction cost and daily water used quantity greatly saved.It features sensitive control,safety,reliability,simple debugging and long duration 四、主要外形及連接尺寸 Schematic diagram of installation 公稱 通徑 DN(mm) 20 25 32 40 50 65 80 100 125 150 200 250 300 350 400 450 500 600 700 800 L 180 180 180 203 203 216 241 292 330 356 495 622 698 787 914 978 978 1295 1446 1956 PN10 D 105 115 135 145 160 180 195 215 245 280 335 390 440 500 565 615 670 780 895 1010 D1 75 85 100 110 125 145 160 180 210 240 295 350 400 460 515 565 620 725 840 950 PN16 D 105 115 135 145 160 180 195 215 245 280 335 405 460 520 580 640 705 840 910 1020 D1 75 85 100 110 125 145 160 180 210 240 295 355 410 470 525 585 650 770 840 950 PN25 D 105 110 135 145 160 180 195 230 270 300 360 425 485 550 610 660 730 840 955 1070 D1 75 85 100 110 125 145 160 190 220 250 310 370 430 490 550 600 660 770 875 990 H 342 342 342 395 395 405 430 510 560 585 675 730 760 840 910 1030 1135 1270 1460 1640 H1 247 247 247 278 278 298 313 350 365 420 450 470 490 526 570 610 665 725 865 975 注：安裝示意圖中彈性座封閘閥或蝶閥任選，建議≥ DN350選蝶閥。 Note：Either elastic seat ring sealed gate valve of butterfly valve can be selected in the schematic diagram of installation.Recommended to select the butterfly valve in case of≥DN350
