Abstract

The invention discloses an anti-corrosion ultrahigh-pressure online piece hanging and taking device and a using method thereof.The anti-corrosion ultrahigh-pressure online piece hanging and taking device comprises a piece hanging device and a piece taking device.The piece hanging device comprises a welding nipple and a piece hanging sealing rod.A movable sealing rod is designed and installed in an upper hole in a sealing cavity of the piece taking device, an ultrahigh-pressure combined seal for rods is designed and installed around the upper hole in the sealing cavity and the movable sealing rod, a force application rod is installed at one outer end of the sealing cavity, the end, in the sealing cavity, of the movable sealing rod is connected with a piece taking head, the lower portion of the sealing cavity is connected with an upper connector, the upper connector is connected with a high-pressure ball valve, the high-pressure ball valve is connected with a lower connector, and a vent valve is installed on a connecting pipe of the upper connector.Due to the design of an anti-corrosion nipple in the piece hanging device, corrosion of the piece hanging device and a welding line can be effectively controlled, and thus the piece hanging device can be used for a long time.Due to the matching design of the movable sealing rod, the piece taking head, an upper sealing nipple and a pressure release sealing rod, the high-pressure ball valve can be replaced once leakage occurs, the piece hanging and taking device can be used for a long time, and the operating force in the piece hanging and taking process is small.

Description

technical field [0001] The invention relates to a device for online non-stop production hanging piece picking and hanging of media in a high-pressure container and a pipeline transportation system in operation, and in particular to an anti-corrosion ultra-high pressure online hanging piece picking device and a use method thereof. Background technique [0002] At present, there are many kinds of hanger or device for online non-stop production of pipelines on the market. Due to the defects of their structure and sealing, the following problems exist in the process of use: [0003] One is that the joints of the hanger or device are all O-rings. The sealing pressure of the O-rings is generally lower than 20MPa, which cannot be adapted to gas-liquid high-pressure containers and gas-liquid under high-pressure or ultra-high pressure conditions. The on-line non-stop corrosion test of the pipeline transportation system, and the O-ring is prone to seal failure during use, resulting in...
