In order to control and eliminate the hazards of water hammer in refined oil pipeline, the DANFLO MODEL 20 pilot-operated pressure relief valve is adopted to subtract the water hammer wave in pipeline. Through relieving the oil in pipeline, the volume is changed and the pressure of the oil can be relieved, thus the intensity of the water hammer wave is reduced. Such kind of pressure relief valve has been used in many refined oil pipelines in our country, the practical application reflects that the valve features strong flowing capability and fast response speed. In long distance oil pipeline protection system, DANFLO MODEL 20 pilot-operated pressure relief valve has become one of the critical equipment, it possesses extensive application value.%为了控制和消除长输成品油管道的水击危害,采用DANFLO MODEL 20型先导式泄压阀消减管道中的水击波.该泄压阀通过泄放管道中的油品,使其体积发生变化,油品压能得到释放,从而减弱了水击波的强度.国内已有多条长输成品油管道采用这种泄压阀,实际运行表明该泄压阀具有流通能力强、响应快速的特点.在长输成品油管道保护系统中,DANFLO MODEL 20型先导式泄压阀已成为一种关键设备,具有广泛的应用价值.
