一、概述
LG系列節(jié)流裝置是與差壓計(jì)配套使用的,用于測量液體、蒸汽、氣體的流量。廣泛的應(yīng)用在石油、化工、冶金、電力和輕工等工業(yè)部門。
節(jié)流裝置分孔板、噴嘴、流量管三大類品種,具有結(jié)構(gòu)簡單、精度高、可靠性好、應(yīng)用范圍廣等特點(diǎn)。
作為節(jié)流裝置專業(yè)生產(chǎn)廠家,我公司曾參與起草制訂了差壓式流量計(jì)國家計(jì)量檢定規(guī)程。我公司生產(chǎn)的節(jié)流裝置以品種全,生產(chǎn)工藝成熟,可靠性好,人無我有,人有我全,人全我優(yōu)見長。
二、節(jié)流裝置型號的編制
LG系列節(jié)流裝置代號、型號的編制積技術(shù)參數(shù)和性能: L(流量表)+G(節(jié)流裝置)+節(jié)流元件+取壓方法+取壓形式+公稱壓力.公稱通徑.組成結(jié)構(gòu) (如:LGBJH1.0-100-1 LGQJK1.0-500-14 LGBFK10-200-21等) | |||
節(jié)流元件: B-標(biāo)準(zhǔn)孔板; | 取壓方法: J-角接取壓法; | 取壓形式: H-環(huán)室; | |
組成結(jié)構(gòu): 圖1-圖26(詳見產(chǎn)品的選型樣本)
