BLB 300 Orifice Plate with Carrier Ring Single Bore Pressure Taps Construction Carrier-ring with single bore acc. to DIN 19205 And fixed orifice plate. This can be supplied as an orifice (ISO 5167), a cylindrical orifice, quarter circle nozzle or as a segmental orifice, double coned orifice, according to requirements. The orifice plate welded or screwed into the carrier-ring or the orifice can be machined as a single piece. When mild steel is used,the bore is reinforced with stainless steel. When unusual materials are specified, the orifice plate isscrewed onto the carrier ring.

BLB 300 环室孔板
单膛测压器

构造

DIN 19205单膛载环和固定孔板。根据需要可作为以下产品提供：
ISO 5167孔板，柱面孔板，四分之一喷嘴，圆缺孔板，双锥孔板。
孔板焊接或拧入载环内，孔板也可单件加工。如果使用的是软钢，
内膛就用不锈钢加强。当规定需使用特别材料时，孔板要拧紧在载环上



优点
构造结实实用，孔板容易清洁，因此适用于凝固或沉淀介质，
或适用于不长期使用的设备。

技术数据

公称压力：PN 6 至PN 160 (PN 150 Ibs 至 1500(2500)Ibs)

 公称直径 DN 50 ( 2") to DN 1600 (64" ) to PN 16 (150 Ibs)
DN 50 ( 2") to DN 500 (20") to PN 40 (900 Ibs)
DN 50 ( 2") to DN 350 (14") to PN 160 (1500 Ibs)
DN 50 ( 2") to DN 250 (10") to PN 320 (2500 Ibs)
外径：载环(光滑密封表面)外径计算方法：螺栓孔直径－法兰螺栓直径。
榫槽载环：d4=表面外径＋10mm; 密封环＋16mm。
安装长度：25mm, 40mm, 65mm, 其他长度也可以安装。


内径：我们要根据所提供的数据进行计算，要考虑有关的标准和计算规则

压损：根据d2:D2这个比例公式可得出压损，压损是压差的30％－80％之间，
数据表会提供有关数据。
