对于石油化工企业而言,其在生产过程中,受多种因素的影响,容易使设备或者管道内的压力升高,进而对设备或管道造成损害,甚至带来安全威胁。通过给设备或者管道安装安全阀,可以在压力较高的情况下,使安全阀自动开启,释放介质,从而避免了安全事故的发生。因此,安全阀在石油化工生产装置中具有重要意义。 For petrochemical enterprises, their production process, under the influence of many factors, easy to make the pressure inside the equipment or pipeline, and thus cause damage to equipment or pipes, and even bring security threats. By installing a safety valve on a piece of equipment or a pipe, the safety valve can be automatically opened and the medium released under high pressure to avoid a safety accident. Therefore, the safety valve in the petrochemical plant is of great significance.
