[0002] A gas compressor is a power device that converts mechanical energy into gas pressure energy. It is often used to provide gas power for pneumatic tools. It is also commonly used to pressurize oxygen, hydrogen, ammonia, natural gas, coke oven gas, inert gas and other media in the petrochemical, drilling, metallurgical and other industries. In a gas compressor, in order to ensure the sealing inside the compressor, a sealing ring needs to be installed at the connection.

[0003] The existing gas compressor packing seal ring is generally provided in an integrated manner, which will wear out with use, thereby causing the sealing effect to decrease, thus eventually affecting normal use.

[0004] Therefore, it is necessary to propose a gas compressor packing seal ring to solve the above problems. Utility Model Content

[0009] Preferably, the first flexible sealing rubber ring is arranged at two ends of the outer side of the packing sealing ring body, and the second flexible sealing rubber ring is arranged at two ends of the inner cavity of the packing sealing ring body and corresponds to the first flexible sealing rubber ring one by one.

[0010] Preferably, a receiving groove is provided on the inner side of the side wall of the packing sealing ring body, and the support plate is movably connected to the inner side of the receiving groove.

[0011] Preferably, both ends of the bidirectional screw rod are rotatably connected to the inner side of the installation cavity through bearings.

[0012] Preferably, one end of the bidirectional screw extends to the end of the packing sealing ring body and is provided with a driving body for driving the bidirectional screw to rotate.

[0013] Preferably, a hidden groove for accommodating the driving body is provided at one end of the packing sealing ring body.
