Description
Art
The utility model relates to a kind of fluid connecting device technical field, specifically relates to a kind of end cap.
Background technique
In gas pipeline, pipeline road, tap water pipe line, hydraulic pressure or pneumatic compression devices, the place such as pipeline is when considering that the later stage, expansion needed, and leave some connection branch roads for subsequent use, these connection branch roads for subsequent use need to close with end cap.
At present, existing connection branch road end cap used for subsequent use relies on short bolt and seal ring to realize shutoff, and after causing one period of spreadable life, shutoff place occurs leaking because pressure-bearing is large and seal ring is aging, and there is hidden danger of quality, Security is low.
Summary of the invention
Short bolt and seal ring is relied on to realize shutoff in order to overcome existing connection branch road end cap used for subsequent use, after causing one period of spreadable life, shutoff place occurs leaking because pressure-bearing is large and seal ring is aging, there is hidden danger of quality, the defects such as Security is low, the utility model provides a kind of new end cap.
The utility model specifically solves the technical solution that its technical problem adopts: end cap comprises plug 11, the boss place 11-1 of plug, seal ring 12, branch road component 13, one-way bottom valve sheet 14, the groove 14-1 of one-way bottom valve sheet, the boss place 14-2 of one-way bottom valve sheet.Wherein, the male thread portion of plug 11 is housings of finding time, plug 11 be the boss place 11-1 of the plug with square hole bottom; One-way bottom valve sheet 14 is thin-walled parts of anti-corrosive rubber material, and the outside diameter of one-way bottom valve sheet 14 equals the external diameter of plug 11 male thread portion; One-way bottom valve sheet 14 is assembled to the boss place 11-1 of the plug of plug 11 by the boss place 14-2 of one-way bottom valve sheet, and plug 11 and one-way bottom valve sheet 14 are assembled into plug assembly parts; The one-way bottom valve sheet 14 of plug assembly parts can one direction be rotated down around the groove 14-1 of one-way bottom valve sheet; Plug assembly parts is threaded connection through seal ring 12 and is assembled on branch road component 13; When gas, oil or water are fully loaded with in branch road component 13 inside, the pressure of gas, oil or water makes one-way bottom valve sheet 14 be close to the lower end surface of plug 11, and the housing of finding time of one-way bottom valve sheet 14 and plug 11 forms enclosed cavity, has decompression and sealing double action; Seal ring 12 and enclosed cavity realize two-stage sealing; When branch road component 13 internal dead gas, oil or water, the find time gas of enclosure interior infiltration, oil or water of plug 11 pushes one-way bottom valve sheet 14 open, flows back in branch road component 13.
The beneficial effects of the utility model are, adopt a kind of end cap, solving connection branch road end cap used for subsequent use at present relies on short bolt and seal ring to realize shutoff, after one period of spreadable life, shutoff place occurs leaking because pressure-bearing is large and seal ring is aging, there is hidden danger of quality, the problems such as Security is low.Its structure is simple, and dismounting is convenient, and once decompression, two-stage sealing, improve the Security of device greatly.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of a kind of end cap of the utility model.
11. plugs in figure, the boss place of 11-1. plug, 12. seal rings, 13. branch road components, 14. one-way bottom valve sheets, the groove of 14-1. one-way bottom valve sheet, the boss place of 14-2. one-way bottom valve sheet.
Embodiment
Below in conjunction with drawings and Examples, the utility model patent is further described.
See accompanying drawing, a kind of end cap comprises plug 11, the boss place 11-1 of plug, seal ring 12, branch road component 13, one-way bottom valve sheet 14, the groove 14-1 of one-way bottom valve sheet, the boss place 14-2 of one-way bottom valve sheet.Wherein, the male thread portion of plug 11 is housings of finding time, plug 11 be the boss place 11-1 of the plug with square hole bottom; One-way bottom valve sheet 14 is thin-walled parts of anti-corrosive rubber material, and the outside diameter of one-way bottom valve sheet 14 equals the external diameter of plug 11 male thread portion; One-way bottom valve sheet 14 is assembled to the boss place 11-1 of the plug of plug 11 by the boss place 14-2 of one-way bottom valve sheet, and plug 11 and one-way bottom valve sheet 14 are assembled into plug assembly parts; The one-way bottom valve sheet 14 of plug assembly parts can one direction be rotated down around the groove 14-1 of one-way bottom valve sheet; Plug assembly parts is threaded connection through seal ring 12 and is assembled on branch road component 13; When gas, oil or water are fully loaded with in branch road component 13 inside, the pressure of gas, oil or water makes one-way bottom valve sheet 14 be close to the lower end surface of plug 11, and the housing of finding time of one-way bottom valve sheet 14 and plug 11 forms enclosed cavity, has decompression and sealing double action; Seal ring 12 and enclosed cavity realize two-stage sealing; When branch road component 13 internal dead gas, oil or water, the find time gas of enclosure interior infiltration, oil or water of plug 11 pushes one-way bottom valve sheet 14 open, flows back in branch road component 13.
