Explain: This series collects all kinds of connection forms and structural couplings,nipples,nozzles,rotary couplings, thermowells and other products in the automatic control instrument pipeline system.It is an essential connecting piece in the pipeline with a wide range of varieties, specifications and applications.Pressure gauge connector YZG12 series is a widely used connector.As long as there is a pressure gauge,there are YZG12 series connectors.The manufacturing material of YZG12 series joints shall be the same as or higher than the pipe material.The commonly used standard parts shall be made of 20# steel, 1Cr18Ni9Ti, 316 and 316L,and shall be selected at a higher level.The temperature can adapt to a wide range, usually T≤800°C, and it can be used normally. 性能規(guī)范： □公稱壓力：1.0MPa～3.2MPa □適用溫度：-70℃～+450℃ □制造材料：20#,H62,1Cr18Ni9Ti,316L,0Cr18Ni12Mo2Ti □執(zhí)行標(biāo)準(zhǔn)：《儀表工手冊》樂嘉謙著 第五篇 儀表安裝>>第三章 儀表加工件>>第一節(jié) 儀表接頭
YZG12-2 壓力表組合接頭一端為外螺紋，螺紋為英制ZG1/8"和ZG1/4"兩種，接別的儀表或閥門。另一端為內(nèi)螺紋，接壓力表。按壓力表的螺紋，內(nèi)螺紋有M10×1，M12×1.25，M14×1.5，M20×1.5和G1/2"五種。 One end of YZG12-2 pressure gauge combination connector is external thread,and the thread is British ZG1/8"and ZG1/4",which is connected to other instruments or valves.The other end is internal thread,connected to pressure gauge.According to the thread of pressure gauge,the internal thread has M10×1，M12×1.25，M14×1.5，M20×1.5 and G1/2".
