Abstract
The invention provides an anti-seepage connecting device for pipelines. The anti-seepage connecting device comprises a male connector device body and a female connector device body which are externally connected with the pipelines correspondingly. The male connector device body is provided with a boss. The female connector device body is provided with a concave cavity. The shape of the boss is matched with that of the concave cavity. The outer surface of the boss is provided with a boss thread. The concave cavity is internally provided with a concave cavity thread. The boss thread and the concave cavity thread can be matched and rotationally connected and are each of a double-thread structure. The anti-seepage connecting device for the pipelines has the advantages and positive effects of being simple in structure, quick in installation and good in anti-seepage effect.
Description
Technical field
The invention belongs to liquid transporting apparatus technical field, particularly to a kind of antiseep pipeline connecting device.
Background technology
In prior art, present Household tap water pipe major part adopts flexible pipe to arrange, flexible pipe replaces present galvanized pipe gradually.Use this properties of materials of flexible pipe major embodiment, it is possible to random curved directly the joint of tube and tube adopts glue bonding, so installs speed, uses auxiliary device little, unlike galvanized pipe, in addition it is also necessary to bolt die equipment, cut off saw blade etc..Although the connection between flexible pipe and flexible pipe is fast, but there is bigger defect, sometimes due to function of glue coating is uneven, cause part poorly sealed, cause side leakage phenomenon.Sometimes, after finishing test of leaking, depended on watertight illusion on the surface, through working procedures such as movement, poling, landfills, occurred that trickle leaking not easily is discovered, very easily cause the loss on finishing.
Summary of the invention
The problem that the invention to solve is to provide a kind of quick for installation, antiseep pipeline connecting device that antiseep is effective.
For solving above-mentioned technical problem, the invention the technical scheme is that
A kind of antiseep pipeline connecting device, including male joint device and female joint device, described male joint device and female joint device external connecting line respectively, described male joint device is provided with boss, and described female joint device is provided with cavity, described boss and described cavity shapes and matches, described boss outer surface is provided with boss screw thread, be internally provided with cavity screw thread, described boss screw thread and the so-called cavity screw thread energy matching rotation of described cavity connect, and described boss screw thread and so-called cavity screw thread are double thread structure.
Also including fastening sleeve, described fastening sleeve is socketed in described male joint device and the link position place of described female joint device.
Described fastening sleeve is provided with female thread, and the excircle of described male joint device and described female joint device is provided with the external screw thread matched with described fastening sleeve.
The boss bottom place of described male joint device is provided with sealing ring.
Described sealing ring and described fastening sleeve contact.
The top diameter of described boss and the proportion of base diameter are 1:1.25-1.3.
The tapering of described boss is 15-30 degree.
The invention has the advantage that and has the benefit effect that
1, the connection technical ability that screws of male joint device described in simple in construction and described female joint device realizes the effect of antiseep；Effect plus described fastening sleeve, it is achieved dual antiseep purpose；
2, double thread structure reaches rotation and the effect closely, not disconnected；
3, install simple and direct, work efficiency can be effectively improved；Fastening is installed reliable；
4, the design of the proportion of the tapering of boss and the top diameter of boss and base diameter, it is ensured that what screw is subject to force intensity, extends service life.
Accompanying drawing explanation
Fig. 1 is the structure chart of these innovation and creation；
1 male joint device, 2-female joint device, 3 cavitys,
4 boss, 5 cavity screw threads, 6 boss screw threads,
7 sealing rings, 8 fastening sleeves, 9-bush whorl.
Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the invention is further described.
Such as Fig. 1, a kind of antiseep pipeline connecting device, including male joint device 1 and female joint device 2, described male joint device 2 and female joint device 2 external connecting line respectively, described male joint device 1 is provided with boss 4, described female joint device 2 is provided with cavity 3, described boss 4 and described cavity 3 matching form close, described boss 4 outer surface is provided with boss screw thread 6, described cavity 3 be internally provided with cavity screw thread 5, described boss screw thread 6 and so-called cavity screw thread 5 can matching rotation connect, and described boss screw thread 6 and so-called cavity screw thread 5 are double thread structure.Double thread structure reaches rotation and the effect closely, not disconnected.
The simple structure screwing connection of described male joint device and described female joint device, it is achieved the effect of antiseep.
Also including fastening sleeve 8, described adapter sleeve jacket casing 8 is connected on described male joint device 1 and the link position place of described female joint device 2；Fit sealing effect plus fastening sleeve, it is achieved dual antiseep purpose.
Described fastening sleeve 8 is provided with female thread 9, and the excircle of described male joint device 1 and described female joint device 2 is provided with the external screw thread matched with described fastening sleeve 9.
Bottom the boss 4 of described male joint device 1, place is provided with sealing ring 7.
Described sealing ring 7 and described fastening sleeve 8 contact.
The top diameter of described boss 4 and the proportion of base diameter are 1:1.25-1.3.
The tapering of described boss 4 is 15-30 degree.Optimum is 15-20 degree.
The design of the proportion of the tapering of boss and the top diameter of boss and base diameter, it is ensured that what screw is subject to force intensity, extends service life.
Above the embodiment of the invention is described in detail, but described content has been only the preferred embodiment of the invention, it is impossible to be considered the practical range for limiting the present invention.All equalizations made according to the invention scope change and improvement etc., all should still belong within this patent covering scope.
