yje系列膜盒壓力表
theca case pressure gauge
簡 介
膜盒壓力表采用膜盒作為測壓力敏感元件。測量對銅合金不起腐蝕作用、無爆炸危險(xiǎn)的氣體的微壓和真空,廣泛應(yīng)用于鍋爐通風(fēng)、氣體管道、燃燒裝置及其它類似設(shè)備上。
不銹鋼膜盒壓力表在普通膜盒壓力表的基礎(chǔ)上導(dǎo)壓系統(tǒng)及外殼均采用了不銹鋼材料。應(yīng)用于耐腐蝕要求較高的工藝流程中對各種氣體介質(zhì)的壓力和真空的測量。
在膜盒壓力表的基礎(chǔ)上內(nèi)部填充阻尼液和緩沖裝置即成耐震膜盒壓力表具有良好的耐震性能;適用于被測介質(zhì)的壓力有強(qiáng)烈脈沖變化或壓力沖擊和在生產(chǎn)工藝中經(jīng)常突然卸荷的場合,以及環(huán)境震動(dòng)較大的場所。
膜盒壓力表與相應(yīng)的電氣器件配套使用,即成為電接點(diǎn)膜盒壓力表,可達(dá)到對被測壓力系統(tǒng)實(shí)現(xiàn)預(yù)先設(shè)定的zui大或zui小壓力值的雙位自動(dòng)控制和發(fā)信(報(bào)警)的目的。

brief introduction
theca box pressure gauges are used to measure micro pressure and negative pressure of gas that has no danger of explosion and does not erode alloy. adopting theca box as sense organ, the gauges are widely applied to boiler ventilating, gas pipeline, burning device and other similar devices.
based on common theca box pressure gauges, stainless theca box pressure gauges introduce stainless material uesd in pressure leading system and crust. the gauges are not only suitable for measuring micro pressure and negative pressure of various gas medium in craftwork flow, which require higher performance of corrosion resistance, but also can be applied to boiler ventilating, gas pipeline, burning device and other similar devices.
構(gòu)成示意圖
結(jié)構(gòu)原理 structure
儀表由導(dǎo)壓系統(tǒng)(包括接頭、膜盒等)、傳動(dòng)機(jī)構(gòu)、指示裝置、和外殼等組成(電接點(diǎn)膜盒壓力表還包括磁助電接點(diǎn)裝置、調(diào)節(jié)裝置及航空插頭等)。
當(dāng)被測介質(zhì)作用于膜盒時(shí),其管端產(chǎn)生相應(yīng)的彈性變形——位移,經(jīng)傳動(dòng)機(jī)構(gòu)放大后,由指示裝置在度盤上把被測壓力指示出來。
電接點(diǎn)膜盒壓力表在指示裝置將被測壓力顯示在儀表度盤上的同時(shí),指針帶動(dòng)電接點(diǎn)裝置的活動(dòng)觸點(diǎn)與設(shè)定指針上的觸頭(上限或下限)相接觸的瞬時(shí),控制系統(tǒng)接通或斷開電路,以達(dá)到自動(dòng)控制和發(fā)信報(bào)警的目的。
the meter is composed of pressure leading system (including joint and theca box, etc), driving framework, indicating device and crust.(electric contact theca box dressart meter in dude,magnetism of electric conacd)
when theca box is operated by measured medium, its end will produce elasticity distortiondisplacement. the displacement is enlarged by driving machine, and measured pressure value will be shown up by indicating device on meter dial.
when indicating device installed at electric contact theca box pressure meter shows the measured pressure value on meter dial, the pointer will simultaneously drive active contactor of electric contact device to meet the contactor (upper limit or lower limit) installed at the pointer. thus control system will switch on or cut off circuit, and both aims of autocontrol and signal sending are all achieved
