微啟式安全閥概述:
上海銳茨閥門有限公司是國內(nèi)生產(chǎn)安全閥的主導(dǎo)廠,廠內(nèi)建有遠(yuǎn)東*的安全閥測試中心,國產(chǎn)第 一臺安全閥就是我廠誕生的。二十多年來,銳茨牌安全閥的品種已發(fā)展到百余個系列,千余個規(guī)格,產(chǎn)品廣泛應(yīng)用于鍋爐、石化、電站以及國防工業(yè)。并為國內(nèi)第 一座核電站秦山核電站研制成功了第 一批核級安全閥。 銳茨牌安全閥主要產(chǎn)品系列分別榮獲機(jī)械部信得過產(chǎn)品,上海市優(yōu)質(zhì)產(chǎn)品稱號,國家銀質(zhì)獎。 銳茨牌安全閥是受壓設(shè)備、容器或路上的 佳超壓保護(hù)裝置。當(dāng)設(shè)備壓力升高達(dá)到預(yù)定值時,安全閥自動開啟,繼而全量排放,防止設(shè)備壓力繼續(xù)升高;當(dāng)壓力降低到規(guī)定值時,安全閥及時自動關(guān)閉。銳茨牌安全閥是選用者為保護(hù)工程設(shè)備安全運行的 理想的, 科學(xué)的明智選擇。

先導(dǎo)式安全閥Ax46F(Y)
本發(fā)明公開了一種帶同軸旋轉(zhuǎn)閥門的試管,包括*管體,所述*管體下方設(shè)置有底部區(qū)域,所述底部區(qū)域上設(shè)置有導(dǎo)流孔;還包括,第二管體,套設(shè)于所述*管體,包括能夠與所述導(dǎo)流孔相配合密封的密封部件,所述第二管體與所述*管體同軸方向旋轉(zhuǎn)一定角度后,實現(xiàn)了所述導(dǎo)流孔開啟與關(guān)閉的轉(zhuǎn)換。本發(fā)明的有益效果:本發(fā)明在現(xiàn)有試管的底部增加一個旋轉(zhuǎn)閥門(管體),通過開通閥門隨后以真空吸取的方式將管內(nèi)的溶液從底部舍棄,新的溶液則從頂部的開口加入進(jìn)來,全過程中能節(jié)省多個槍頭,并容易實現(xiàn)操作自動化。
