Description

Fire-free perforation sealing device for metering room separator Technical Field The utility model relates to the technical field of oilfield equipment pipeline maintenance, in particular to a fire-free perforation sealing device for a metering room separator. Background In the oil field work, be equipped with a plurality of dead blind section pipelines on the separator between the measurement, dead blind section pipeline tip is because receive the erosion and the extrusion of pipeline internal pressure fluid for a long time after long-time operation, can not avoid producing damage, perforation phenomenon, but because there is inflammable and explosive composition in the fluid that flows through in the dead blind section pipeline, consequently can not carry out the operation of moving fire in carrying out maintenance treatment, leads to maintenance work to be difficult to implement. In the prior art, there is a no-moving fire pipeline leakage repairing device, through adding the sleeve pipe after cutting off the pipeline and reconnecting two sections of pipelines so as to seal the perforation, but the device structure is to the T-shaped unilateral pressure structure of the separator branch pipe, and because the T-shaped joint cannot be provided with fixing components such as packing, the perforation position cannot be sealed and fixed, the T-shaped joint cannot be sealed at a close distance, and the no-moving fire pipeline leakage repairing device is not suitable for repairing perforation of dead blind section pipelines of the separator between metering. In view of the above shortcomings, a fire-free perforation closing device for a metering room separator is provided. Disclosure of Invention The utility model aims to provide a fire-free perforation closing device for a metering room separator, which is used for overcoming the defect that the short-distance position sealing of a T-shaped joint cannot be realized in the prior art and is not suitable for repairing perforation of a dead blind section pipeline of the metering room separator. In order to achieve the above object, the present utility model provides a fire-free perforation closing device for a separator between metering, comprising: The inner wall of the sealing cylinder is provided with a pipe thread, and the inner diameter of the pipe thread is matched with the outer diameter of the repaired pipeline; The top end of the sealing cylinder is sealed, the bottom end of the sealing cylinder is provided with an opening, and the top end of the repaired pipeline penetrates through the opening of the sealing cylinder to be matched with the pipe thread; The bottom end of the sealing cylinder is provided with a sealing gland, a through mounting hole is arranged in the middle of the sealing gland, and a repaired pipeline penetrates into the sealing cylinder through the mounting hole to be connected with the pipe in a threaded fit manner.
