An electric heating sealing type pipeline sealing device

Abstract

The invention relates to the technical field of pipeline sealing, in particular to an electric heat sealing pipeline sealing device, which comprises a plastic tube, a sealing ring is sleeved on the outside of the plastic tube, a positioning ring is slidably connected to the inside of the plastic tube, and a positioning ring is slidably connected to the outside of the sealing ring. A sealing tube is sleeved, the outer side of the sealing tube is slidably connected to a fixing frame, the outer side of the fixing frame is slidably connected to a rotating shaft, and the rotating shaft runs through the fixing frame, the rotating shaft is slidably connected to the fixing frame, and one end of the rotating shaft is fixedly connected to an electric Heating block, the other end of the rotating shaft is rotatably connected with a connecting rod, the other end of the connecting rod is fixedly connected with a fixed rod, the left end of the fixed rod is fixedly connected with a sliding rod, and the other end of the sliding rod slides with the fixed frame Connection, the outer side of the fixed rod is provided with a rack. In the present invention, through the provided electric heating block, this arrangement cooperates with the melted sealing ring to achieve a sealing effect similar to welding, thereby avoiding the phenomenon that the sealing effect is not guaranteed.

Description

technical field [0001] The invention relates to the technical field of pipeline sealing, in particular to an electric heating sealing type pipeline sealing device. Background technique [0002] Pipeline sealing is to protect the items in the pipeline by sealing the pipeline, preventing some gaseous, liquid or solid pollutants from damaging the items in the pipeline, and preventing the normal operation of the lines in the pipeline from being affected. Sealing is carried out to prevent the influence of external factors. There are generally four types of sealing methods, but the best is welding-type sealing. This method has the best sealing performance. The sealing effect of some traditional sealing methods is not very good, so , there is an increasing demand for an electric heat sealing type pipe sealing device. [0003] Some pipeline sealing methods currently on the market are to seal the pipeline by inflating the sealing bag or brushing and inflating the sealing bag with a ...

[0002] Pipeline sealing is to protect the items in the pipeline by sealing the pipeline, preventing some gaseous, liquid or solid pollutants from damaging the items in the pipeline, and preventing the normal operation of the lines in the pipeline from being affected. Sealing is carried out to prevent the influence of external factors. There are generally four types of sealing methods, but the best is welding-type sealing. This method has the best sealing performance. The sealing effect of some traditional sealing methods is not very good, so , there is a growing demand for an electrothermally sealed pipe seal

[0003] Some pipeline sealing methods currently on the market are to seal the pipeline by inflating the sealing bag or brushing and inflating the sealing bag with a fixed plug. This method is very complicated to operate, and it is impossible to confirm whether the sealing is complete. , there is a phenomenon that the seal is not complete, and in the process of glue brushing, the glue will spill and pollute the environment, and it is easy to get on the operator, which is not easy to dispose of, and there is also a certain danger in the process of inflation, because the seal If the quality of the bag is not good, it may explode when it is inflated, thus endangering the safety of the operator. Therefore, an electric heating sealing type pipe sealing device is proposed to solve the above problems
