Abstract
The invention provides a leakage-proof pipeline connecting device. The leakage-proof pipeline connecting device comprises a male connector and a female connector, wherein the male connector and the female connector are respectively and externally connected with pipelines; the male connector is provided with a boss, the female connector is provided with a concave cavity, and the shape of the boss is matched with that of the concave cavity; a boss thread is formed in the outer surface of the boss, a concave cavity thread is formed in the concave cavity, the boss thread and the concave cavity thread can be connected in a matching and rotating manner, and the boss thread and the concave cavity thread both adopt double-thread structures. The leakage-proof pipeline connecting device disclosed by the invention has the advantages and the benefits of simple structure and good leakage-proof effect, and the mounting is quick.
Description
Technical field
The invention belongs to liquid transporting apparatus technical field, particularly a kind of leakage proof pipeline connecting device.
Background technique
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, can be random directly curved, the joint of tube and tube adopts glue bonding, installs speed like this, uses accessory little, unlike galvanized pipe, also needs bolt die equipment, cut-out saw blade etc.Although the connection between flexible pipe and flexible pipe is fast, there is larger defect, sometimes because 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 will solve is to provide a kind of quick for installation, leakage proof pipeline connecting device that leakage proof is effective.
For solving the problems of the technologies described above, the technological scheme that the invention adopts is:
A kind of leakage proof pipeline connecting device, comprise tool joint pin device and female joint device, described tool joint pin device and female joint device external connecting pipeline respectively, described tool joint pin device is provided with boss, described female joint device is provided with cavity, described boss and described cavity shapes match, described boss outer surface is provided with boss screw thread, the inside of described cavity is provided with cavity screw thread, described boss screw thread is connected with so-called cavity screw thread energy matching rotation, and described boss screw thread and so-called cavity screw thread are two worm structure.
Also comprise fastening sleeve, described fastening sleeve is socketed in the link position place of described tool joint pin device and described female joint device.
Described fastening sleeve is provided with internal thread, the excircle of described tool joint pin device and described female joint device is provided with the outside thread matched with described fastening sleeve.
The boss bottom place of described tool joint pin device is provided with seal ring.
Described seal 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 advantage that the invention has and good effect are:
1, the simple described tool joint pin device of structure is connected with screwing of described female joint device the effect that technical ability realizes leakage proof; Add the effect of described fastening sleeve, realize dual leakage proof object;
2, two worm structure reaches the effect of revolving and closely, not disconnecting;
3, install simple and direct, can effectively increase work efficiency; Install reliably fastening;
4, the design of the proportion of the tapering of boss and the top diameter of boss and base diameter, ensure that screw by force intensity, extend working life.
Accompanying drawing explanation
Fig. 1 is the structural drawing of these innovation and creation;
1-tool joint pin device, 2-female joint device, 3-cavity,
4-boss, 5-cavity screw thread, 6-boss screw thread,
7-seal ring, 8-fastening sleeve, 9-bush whorl.
Embodiment
Below in conjunction with accompanying drawing, the embodiment to the invention is further described.
As Fig. 1, a kind of leakage proof pipeline connecting device, comprise tool joint pin device 1 and female joint device 2, described tool joint pin device 2 and female joint device 2 external connecting pipeline respectively, described tool joint pin 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, the inside of described cavity 3 is provided with cavity screw thread 5, described boss screw thread 6 can matching rotation be connected with so-called cavity screw thread 5, and described boss screw thread 6 and so-called cavity screw thread 5 are two worm structure.Two worm structure reaches the effect of revolving He closely, not disconnecting.
The simple structure screwing connection of described tool joint pin device and described female joint device, realizes the effect of leakage proof.
Also comprise fastening sleeve 8, described adapter sleeve jacket casing 8 is connected on the link position place of described tool joint pin device 1 and described female joint device 2; Add the fit sealing effect of fastening sleeve, realize dual leakage proof object.
Described fastening sleeve 8 is provided with internal thread 9, the excircle of described tool joint pin device 1 and described female joint device 2 is provided with the outside thread matched with described fastening sleeve 9.
Bottom the boss 4 of described tool joint pin device 1, place is provided with seal ring 7.
Described seal 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, ensure that screw by force intensity, extend working life.
Above the embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the invention scope change and improve, and all should still belong within this patent covering scope.
