上图是典型的储罐安全保护装置安装图。大多数储罐上均安装有呼吸阀、紧急泄放阀（或紧急泄放人孔）和91视频黄色网调节阀等装置。呼吸阀能够在泵注入/抽出介质或热交换的条件下，提供压力或真空泄放，从而防止储罐破裂或被抽瘪。紧急泄放阀（或紧急泄放人孔）具有两个功能：一是快速泄放由于罐周围有火情或超过设计流量的介质注入储罐造成的超压；二是在常规吸阀未正常开启的且压力恒定的情况下吸入空气进行卸压（针对带吸阀的紧急泄放阀而言）。上海91视频色下载APP阀门有限公司主营阀门有：91视频看看簧色(91视频黄色网91视频看看簧色,可调式91视频看看簧色,波纹管91视频看看簧色,活塞式91视频看看簧色,91视频WWW免费下载91视频看看簧色,先导式91视频看看簧色,空气91视频看看簧色,氮气91视频看看簧色,水用91视频看看簧色,自力式91视频看看簧色,比例91视频看看簧色)、安全阀、保温阀、低温阀、球阀、截止阀、闸阀、止回阀、蝶阀、过滤器、放料阀、隔膜阀、旋塞阀、柱塞阀、平衡阀、调节阀、疏水阀、管夹阀、排污阀、排气阀、排泥阀、气动阀门、电动阀门、高压阀门、中压阀门、低压阀门、水力控制阀、真空阀门、衬胶阀门、衬氟阀门。91视频黄色网调节阀是一种调节装置，它通过控制高压91视频黄色网的流量使储罐保持较低的91视频黄色网压力，并当储罐中的介质被抽出或罐内91视频黄色网释放热量压力降低时保持罐内正压。阻火器的功能是阻止火焰在91视频黄色网管道系统内的传播以保护储存有易燃性介质的低压储罐。它可以通过阻止外部热量和火焰的传播来保护罐内低闪点的介质，从而提高罐的防火性能和安全性能。通常情况下，将出口通大气的呼吸阀安装于阻火器顶部。

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
