Description
Technical field
The utility model belongs to oil pipes technical field, more particularly to anti-thread gluing sealed fitting.
Background technology
Petroleum gas is the valuable source of the mankind, and in petroleum gas transport, the sealing for improving pipe is proposed
Requirement higher, pipe is connected through a screw thread, and joint easily occurs thread gluing, and how damaged screw both improves sealing, prevent again
Thread gluing, these all propose very high request to the connection of oil pipes.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of anti-thread gluing sealed fitting, including female joint and public affairs
Joint, the female joint inner peripheral surface is machined with internal thread, and the front end corresponding to the internal thread in female joint is sequentially provided with
The shoulder of female joint second, female joint first shoulder, are correspondingly provided with external screw thread in the male joint, the internal thread is equal with external screw thread
It is cylindrical thread, the male joint is the shoulder of male joint second, the male joint second with female joint link position inside
Shoulder is circular conical surface, tilted to tube wall, forms the annular cone angle of an introversion, and the male joint closes on the shoulder system of male joint second
There is a transition conical surface；The female joint is mutually connected in plane, the female joint and the male joint with the shoulder of the male joint second
Second shoulder interference fit.
Preferably, there is one section of smooth anchor ring, the annulus between the shoulder of the female joint second and internal thread leading section
The length in face is about two length of tooth form of external screw thread.
There is one section of smooth anchor ring, when male joint connects with mother between the shoulder of the female joint second and internal thread leading section
When head is fastenedly connected, anchor ring is in outside external screw thread top, and anti-screw thread extrudes thread gluing；
Intermediate incline is formed to the inclined annular cone angle in middle part, the female joint and the male joint second with mesospore inclined-plane
Shoulder interference fit, is effectively ensured connection sealing.
The anti-Thread-sticking pipe joint of the anti-thread gluing of the utility model both preferably ensure that sealing, prevent screw thread to glue again
Button.
Brief description of the drawings
Further illustrate with reference to the accompanying drawings and detailed description：
Fig. 1 is the structural representation of the anti-thread gluing sealed fitting of the utility model embodiment.
