对夹衬胶蝶阀,衬胶蝶阀,对夹蝶阀,蝶阀。蝶阀是用阀杆一起转动的蝶板作启闭件，用以实现阀门的开启、关闭与调节。蝶阀在管路中除了起切断和截流用外，近年来已经把密封性能作为评价的主要指标，受到市场青睐。另外，蝶阀还有体裁积小、重量轻、结构简单等优点，与同参数闸阀比较，平均减轻重量达30~50%，蝶板旋转90度即可实现启、闭过程，又由于转轴两侧蝶板受介质作用力近似相等，转矩相反，因些启闭力矩较小 全衬胶球墨铸铁中线蝶阀一、产品详情 产品名称：全衬对夹衬胶蝶阀 产品特点：设计与制造：GB12238 结构长度：GB12221（20系列） 法兰连接尺寸：GB4216 D71X半衬衬胶蝶阀 部件列表：1．阀体2．阀体衬里3．隔膜4．阀瓣5．阀杆6．阀盖7、手轮 全衬胶球墨铸铁中线蝶阀二、产品用途   密封圈材料代号 适用温度 适用介质 NR ≤85℃ 水、空气、酸碱类 CR ≤85℃ 水、煤气、酸碱类 NBR ≤100℃ 水、油品 EPDM ≤120℃ 水、蒸汽、一般酸碱类 FKM ≤150℃ 水、蒸汽、强酸碱类   全衬胶球墨铸铁中线蝶阀三、材料   阀体 铸铁、球墨铸铁、碳钢、不锈钢 蝶板 铸铁、球墨铸铁、碳钢、不锈钢、碳钢完全包覆橡胶或氟塑料 阀杆 碳钢镀镍磷、不锈钢 阀座密封圈 天然胶NR、氯丁胶CR、丁腈胶NBR、三元乙丙胶EPDM、氟橡胶FKM 手柄 铝合金、碳钢   压力等级：PN（MPa）　1.0　1.6 全衬胶球墨铸铁中线蝶阀四、测试 衬里层：电火花检测  试验与检验按GB/T13927标准  公称压力：PN（MPa）  阀体：PN×1.5 密封：PN×1.1     公称通径  DN 公称压力  MPa 工作压力  MPa L mm D  mm D1 mm n-Φd mm H1 mm H2 mm S mm H3 mm 质量  Kg/kilos 40 1.6 1.0 1.6 1.0 33 150 110 4-18 55 100 235 27 2 50 43 165 125 4-18 64 120 235 27 2.5 65 46 185 145 4-18 80 120 235 27 4.5 80 46 200 160 8-18 112 130 265 27 5.5 100 52 220 180 8-18 90 145 265 27 6.5 125 56 250 210 8-18 112 160 365 32 11.5 150 56 285 240 8-22 135 175 365
