压力容器的安全装置通常指安全泄压装置(安全阀、爆破片等)和压力表、液面计、温度计、切断阀、减压阀等安全附件。一、安全泄压装置安全泄压装置是压力容器的最终保护装置,它具有这样的功能:当容器在正常的工作压力下运行时,保持密封不漏;一旦容器内的压力超过规定,它能自动迅速地排泄出容器内的介质,使容器内的压力始终保持在最高许用压力范围内。安全泄压装置主要有下列几种。 (1)安全阀它是通过阀的开启排气来降低容器内的压力的。当容器内的压力降至正常操作压力时便又自动关闭,以避免一旦容器超压就把
Pressure vessel safety devices usually refers to safety relief devices (safety valves, rupture discs, etc.) and pressure gauges, liquid level gauge, thermometer, shut-off valve, pressure relief valve and other safety accessories. First, the safety relief device Safety relief device is the ultimate protection of pressure vessels, it has such a function: When the container at normal working pressure to run, keep the seal does not leak; once the pressure inside the container exceeds the required, it can Automatically and quickly excreted the media inside the container, the pressure inside the container is always maintained within the maximum allowable pressure range. Safety relief devices are mainly the following. (1) safety valve It is through the valve to open the exhaust to reduce the pressure inside the container. When the pressure in the container drops to normal operating pressure, it will be automatically shut down again to prevent the container from over-pressurizing
