The utility model discloses a virus-detection and removing system, proxy server and method used for network encryption data. The system comprises a client, a server, a proxy server and a anti-virus unit, among which when the proxy server encrypts the data communication between the client and the server, the proxy client and the server will receive the transmitted data pack which is decrypted to the plaintext data and then sent to the anti-virus unit for virus examination and removing, so that the safety plaintext data are re-encrypted and then sent to the server. The anti-virus unit can detect and remove the virus from the plaintext data and inform the examining and removing results to the proxy sever, so as to reduce or even remove the network viral transmission via SSL /TLS cryptographic protocol.

The invention discloses a dual-seal filling rotary compensator which comprises an inner tube, a fastener, an outer tube, a left packing, filling valves, a right packing, a sealing ring and an adapter tube. The inner tube is sleeved with the outer tube; and the adapter tube is connected with the right end of the outer pipe in a sealed mode to form an axial limiting inner tube. The left packing is plugged into a gap between the left sections of the inner tube and the outer pipe and is locked on a flange edge of the outer tube by a gland and the fastener to form a main sealing structure. The sealing ring and the right packing are sleeved between steps of the inner tube and the outer tube to form an auxiliary sealing structure. 4 to 16 filling valves communicated with a main sealing cavity are uniformly distributed on the outer wall of the outer tube to form an online leakage compensation structure. The dual-seal filling rotary compensator is of a dual-seal structure and has a good sealing effect. Importantly, in the using process of the dual-seal filling rotary compensator, once the main sealing structure is leaked, the left packing can be filled by the filling valves to recover the sealing under the condition that the regulation is invalid. The dual-seal filling rotary compensator is simple to carry out online maintenance and is easy to operate; the shutdown maintenance cost is greatly reduced and the potential safety hazard caused by the leakage is also avoided.
