我们是成都立腾仪表科技有限公司：长期供巴歇尔槽明渠流量计本公司巴歇尔槽+明渠流量计量组合销售价格更优惠公司***生产不同型号巴歇尔槽和明渠流量计，超声波明渠流量计，三角堰(PVC，聚丙烯和不锈钢材质都可以),来图加工或单独设计订造，免收设计费。聚丙烯******生产，耐腐耐高温，过强酸强碱不影响使用寿命，使用寿命超过10年以上，以下是巴歇尔槽尺寸.巴歇尔槽的中心线要与渠道的中心线重合,使水流进入巴歇尔槽不出现偏流。巴歇尔槽通水后，水的流态要自由流。巴歇尔槽的淹没度要小于规定的临界淹没度。巴歇尔槽的上游应有大于5倍渠道宽的平直段，使水流能平稳进入巴歇尔槽。即没有左右偏流，也没有渠道坡降形成的冲力。（参见下图）巴歇尔槽安装在渠道上要牢固。与渠道侧壁、渠底连结要紧密，不能漏水。使水流全部流经巴歇尔槽的计量部位。巴歇尔槽的计量部位是槽内喉道段。巴歇尔槽构造图类别序号喉道段收缩段扩散段墙高bLNB1L1LaB2L2KD小型10.0250.0760.0290.1670.3560.2370.0930.2030.0190.2320.0510.1140.0430.2140.4060.27101350.2540.0220.2630.0760.1520.0570.2590.4570.3050.1780.3050.0250.4640.1520.3050.1140.4000.6100.4070.3940.6100.0760.6150.2280.3050.1140.5750.8640.5760.3810.4570.0760.77标准型60.250.600.230.781.3250.8830.550.920.080.8070.300.600.230.841.3500.9020.600.920.080.9580.450.600.231.021.4250.9480.750.920.080.9590.600.600.231.201.5001.00.900.920.080.95100.750.600.231.381.5751.0531.050.920.080.95110.900.600.231.561.6501.0991.200.920.080.95121.000.600.231.681.7051.1391.300.920.081.0131.200.600.231.921.8001.2031.500.920.081.0141.500.600.232.281.951.3031.800.920.081.0151.800.600.232.642.101.3992.100.920.081.0162.100.600.233.002.251.5042.400.920.081.0172.400600.233.362.401.6042.700.920.081.0大型183.050.910.3434.764.271.7943.681.830.1521.22193.660.910.3435.614.881.9914.472.440.1521.52204.571.220.4577.627.622.2955.593.050.2291.83216.101.830.6869.147.622.7857.323.660.3052.13227.621.830.68610.677.623.3838.943.960.3052.13239.141.830.68612.317.933.78510.574.270.3052.132412.191.830.68615.488.234.78513.824.880.3052.132515.241.830.68618.538.235.77617.276.100.3052.13)
