Abstract

The invention discloses a novel pressure test sealing bolt. The novel pressure test sealing bolt comprises a hexagonal bolt head and a guide shaft, the lower portion of the guide shaft is provided with external threads, the lower portion of the external threads is provided with the hexagonal bolt head, a concentric sealing ring groove is formed above the hexagonal bolt head, and the internal diameter of the sealing ring groove is equal to the external diameter of the external threads. The novel pressure test sealing bolt has the advantages of being high in mounting speed and low in losses.

Description

technical field [0001] The invention relates to a sealing bolt, in particular to a pressure testing sealing bolt. Background technique [0002] At present, the head of the pressure test sealing bolt is relatively short, and it is difficult to operate when turning the inner knob of the quick-insert pipe joint, and it is prone to skewing, which will cause the bolt and the wire of the pipe joint to be damaged, resulting in large loss, time-consuming and laborious. [0003] Contents of the invention [0004] The object of the present invention is to provide a sealing bolt for pressure testing with fast installation speed and reduced loss. [0005] In order to achieve the above object, the technical solution of the present invention is to include a hexagonal bolt head and a guide shaft, an outer wire is provided under the guide shaft, a hexagonal bolt head is provided below the outer wire, and a concentric bolt head is provided above the hexagonal bolt head. A seal ring groov...
