    上圖是典型的儲(chǔ)罐安全保護(hù)裝置安裝圖。大多數(shù)儲(chǔ)罐上均安裝有呼吸閥、緊急泄放閥(或緊急泄放人孔)和氣體調(diào)節(jié)閥等裝置。呼吸閥能夠在泵注入/抽出介質(zhì)或熱交換的條件下,提供壓力或真空泄放,從而防止儲(chǔ)罐破裂或被抽癟。緊急泄放閥(或緊急泄放人孔)具有兩個(gè)功能:一是快速泄放由于罐周?chē)谢鹎榛虺^(guò)設(shè)計(jì)流量的介質(zhì)注入儲(chǔ)罐造成的超壓;二是在常規(guī)吸閥未正常開(kāi)啟的且壓力恒定的情況下吸入空氣進(jìn)行卸壓(針對(duì)帶吸閥的緊急泄放閥而言)。上海申弘閥門(mén)有限公司主營(yíng)閥門(mén)有:減壓閥(氣體減壓閥,可調(diào)式減壓閥,波紋管減壓閥,活塞式減壓閥,蒸汽減壓閥,先導(dǎo)式減壓閥,空氣減壓閥,氮?dú)鉁p壓閥,水用減壓閥,自力式減壓閥,比例減壓閥)、安全閥、保溫閥、低溫閥、球閥、截止閥閘閥、止回閥、蝶閥、過(guò)濾器、放料閥、隔膜閥、旋塞閥、柱塞閥、平衡閥、調(diào)節(jié)閥、疏水閥、管夾閥、排污閥、排氣閥、排泥閥、氣動(dòng)閥門(mén)、電動(dòng)閥門(mén)、高壓閥門(mén)、中壓閥門(mén)、低壓閥門(mén)、水力控制閥、真空閥門(mén)、襯膠閥門(mén)、襯氟閥門(mén)。氣體調(diào)節(jié)閥是一種調(diào)節(jié)裝置,它通過(guò)控制高壓氣體的流量使儲(chǔ)罐保持較低的氣體壓力,并當(dāng)儲(chǔ)罐中的介質(zhì)被抽出或罐內(nèi)氣體釋放熱量壓力降低時(shí)保持罐內(nèi)正壓。阻火器的功能是阻止火焰在氣體管道系統(tǒng)內(nèi)的傳播以保護(hù)儲(chǔ)存有易燃性介質(zhì)的低壓儲(chǔ)罐。它可以通過(guò)阻止外部熱量和火焰的傳播來(lái)保護(hù)罐內(nèi)低閃點(diǎn)的介質(zhì),從而提高罐的防火性能和安全性能。通常情況下,將出口通大氣的呼吸閥安裝于阻火器頂部。


    Typical safety equipment installation on a tank is illustrated in above
    figure. Most tanks will have provision for a pressure/vacuum relief valve, an
    emergency relief valve(or emergency relief manhole) and a gas blanket
    regulator。
    The pressure/vacuum relief valve is designed to provide pressure/vacuum relief under normal pump in/out and thermal breathing conditions. Soit protects the tank against rupturing or imploding. The emergency relief valve(emergency relief manhole) has two functions: one is to discharge rapidly theoverpressure developed during the fire around the storage tank or theexcessive fluid intake more than the capacity of pump designed, the other isto intake the air under the constant pressure for the irregular operation ofnormal vacuum relief valve during the unloading (aim at emergency relief
    valve with vacuum part). The gas blanketing regulator is a precision regulatorthat is capable of maintaining a very low gas pressure in the tank bycontrolling the flow of a high pressure blanketing gas. It maintains a positivetank pressure when fluid is pumped out or as fluid temperature decreases.Aflame arrester is designed to inhibit flame propagation in gas piping systemsand to protect low pressure tanks containing flammable liquids. They protectlow flash point liquids from externally caused sources of heat and ignition,providing increased fire protection and safety. A majority of the time, a “vent toatmosphere” pressure/vacuum valve is installed on top of the flame arrester
