| Zusammenfassung: | The utility model relates to a novel high pressure pump capable of bearing high pressure and high-viscosity medium, which belongs to the field of fluid engineerings. The novel high pressure pump is characterized in that a pump cylinder, a piston, a piston rod, a suction valve, a drain valve and a pressure-proof valve device are included, wherein the pressure-proof valve device comprises a main valve body, a valve nozzle, a valve seat apical body, a seal, a flexible graphite, a shaft sleeve, a stud and springs; and symmetrical spring devices are respectively arranged at two ends of the pressure-proof valve. The deposits in the pump can be discharged when the extra gas in the pressure-proof valve is released; and the pressure in the pump becomes moderate, and the load pressure of bearing the working medium of the pump is increased. |
