  Features：

  In the long distance pipeline of oil products, the sudden open and close of the valve, the sudden shutdown of the pump and the sudden seizure of the PIG and so on will cause a sudden change in oil flow in the pipeline, resulting in local overpressure and vibration of the pipeline, thus resulting in pipeline breaking, equipment damage and posing a threat to safety of pipeline operation. In order to prevent water hammer effectively and ensure safe operation of long-distance pipeline, long-distance pipeline must have perfect pressure relief system. In addition to using regulating valve to regulate inlet and outlet pressure and pressure advance protection, surge relief valve is widely used to prevent the pipeline from ultra high pressure.

  HTSJ series surge relief valve is an automatic valve for preventing water hammer from occurring and effectively protecting pipeline safety and smooth operation. When the liquid in the pipeline hits the water hammer and reaches the setting value of the surge relief valve, the surge relieverwill be opened quickly, and some oil products will spilled into the pressure relief tank. Because of the change of the volume of the liquid in the pipeline which is caused by the opening of the surge reliever, the pressure energy of the liquid can be released, and the strength of the water hammer pressure wave is reduced, so the safety purpose of protecting the pipeline and the equipment has been reached.

  Product characteristics:

  The circulation capacity is strong, which can effectively avoid the occurrence of water hammer caused by sudden events, thus ensure the safety of pipeline in the oil transmission process.

  The reaction is sensitive. The pressure relief valve can track the change of the water hammer pressure at the front end of the valve. When the pressure at the front end of the valvereaches the pressure setting of the water hammer, the valve opens quickly and it will not close automatically until the water hammer pressure wave attenuates to the setting value.

  No need for external impetus and operation, it will realize water hammer protection by self-sensing system pressure
