| description | The utility model provides a directional pipe body rear cover structure which comprises a composite sealing ring and a composite cover plate, the composite sealing ring is internally and fixedly connected with the composite cover plate, and a step through hole is formed in the composite sealing ring and used for installing a screw, so that the position of the composite cover plate is limited after the composite sealing ring is assembled; a presplitting groove is formed in the composite cover plate, is in a hexagonal star shape, is sunken from outside to inside, and is split and broken to release the pressure of a pipe body after being impacted by high-temperature pressure. According to the directional pipe body rear cover structure, the hexagonal-star-shaped pre-splitting groove is formed in the composite rear cover, the pre-splitting groove does not penetrate through the composite rear cover, the whole composite rear cover is still in a closed state, a sealing foundation can be provided for a pressure storag |
