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
The present invention relates to a kind of sealing bolt, is a kind of pressure testing sealing bolt specifically.
Background technique
Current pressure testing sealing bolt, head is shorter, and to not easy to operate during Quick-insertion type pipe joint inner button, easily occur crooked phenomenon and cause the silk of bolt and pipe joint to be destroyed, loss is large, wastes time and energy.
Summary of the invention
Object of the present invention provides a kind of installation rate fast, the pressure testing sealing bolt reduced the wastage.
For achieving the above object, technological scheme of the present invention is: comprise hex head bolt head, the axis of guide, is provided with outer silk below the described axis of guide, is provided with hex head bolt head below described outer silk, be provided with concentric seal groove above described hex head bolt head, it is direct outward that described seal groove inner diameter equals outer silk.
Owing to adopting technique scheme, beneficial effect of the present invention:
The use of the axis of guide, can not be crooked when bolt is tightened, and avoids the damage of screw thread, reduce loss, do not need adjustment, improve installation rate.
Accompanying drawing explanation
Now the present invention will be further described by reference to the accompanying drawings.
Fig. 1 is structural representation of the present invention.
In figure: 1, outer silk, 2, the axis of guide, 3, hex head bolt head, 4, seal groove.
Embodiment
As shown in Figure 1, comprise hex head bolt head 3, the axis of guide 2, below the described axis of guide 2, be provided with outer silk 1, below described outer silk 1, be provided with hex head bolt head 3, be provided with concentric seal groove 4 on the upside of described hex head bolt head 3, it is directly outer that described seal groove 4 inner diameter equals outer silk 1.
Claims (1)
1. novel pressure testing sealing bolt, comprise hex head bolt head, the axis of guide, it is characterized in that: below the described axis of guide, be provided with outer silk, below described outer silk, be provided with hex head bolt head, be provided with concentric seal groove above described hex head bolt head, it is direct outward that described seal groove inner diameter equals outer silk.
