The invention discloses a dynamic sealing structure resistant to high temperature and high pressure. The dynamic sealing structure which comprises a plunger cylinder block. A plunger is disposed in the plunger cylinder block. A guide sleeve sleeves the plunger. A pressing cap sleeves the rear end of the guide sleeve. A first sealing ring is disposed at the front end of the guide sleeve. A flat gasket is disposed at the rear end of the first sealing ring. A triangular gasket is disposed between the flat gasket and the guide sleeve. An inner lip is disposed at the inner edge of the front end of the first sealing ring. An outer lip is disposed at the outer edge of the front end of the first sealing ring. The dynamic sealing structure has the advantages that the structure is resistant to the high temperature of 300 DEG C and the high pressure of 200MPa, and the sealing structure is effective, reliable and long in sealing service life; a sealing ring is made of the mixture of teflon, carbon and graphite, the temperature resistance and mechanical strength problems of the sealing ring are effectively solved, and the sealing structure can satisfy technical requirements; the sealing structure is simple in structure, few in sealing parts, high in reliability, low in design and manufacturing cost, easy to maintain and long in sealing service life.
Description
technical field [0001] The invention relates to a sealing structure, in particular to a high temperature and high pressure self-tightening dynamic sealing structure. Background technique [0002] The basic function of the hydraulic seal structure is to prevent or limit the leakage of liquid. In the existing dynamic sealing structure, such as the piston sealing structure, the pressure of the sealing liquid usually does not exceed 30MPa, and the temperature does not exceed 80°C. Therefore, the sealing ring structure is generally made of formed sealing rings such as "○" rings and "V" rings. seal. In the supercharger plunger seal structure for the cold isostatic press, the sealing pressure can reach 200MPa, but the temperature of the sealing medium does not exceed 80°C. At the same time, the sealing structure is relatively complicated, the maintainability is poor, and the manufacturing cost is high. High-pressure sealing types can generally be divided into three categories: (...
