This pipe joint is in use, will need the one of pipe fitting connected to be inserted into the grafting chamber of body rear and make pipe
Part end abuts against on face, is mutually fixed pipe fitting with pipe joint by the common fixed form such as welding；Again another
It is arranged a nut on the outside of a pipe fitting, and flaring processing is carried out to the end of the pipe fitting, so that nut will not be deviate from from pipe fitting,
Another pipe fitting is set on the outside of body front end, and is connected by nut with the external screw thread on the outside of body rear, can be realized
To the connection between two pipe fittings.Because nut is standard component, the welding and flaring of pipe fitting can be implemented at the construction field (site), so right
It only needs to produce this pipe joint in the structure that pipeline is attached, the pipe fitting connection in face of different size also only needs to give birth to
The pipe joint of different size is produced, structure is simple, and easy to process, processing cost is low.
In above-mentioned pipe joint, the grafting chamber is cylindrical.
As another situation, in above-mentioned pipe joint, the grafting chamber is in prism-shaped.
In above-mentioned pipe joint, step surface, the step are formed between the outside of the front and rear end of the main body
Be provided at face can for pipe fitting end against sealing ring in a ring.
In above-mentioned pipe joint, several recessed annular seal grooves are offered on the outside of the body front end, it is described
The quantity of sealing element and the quantity of seal groove are identical and be arranged in a one-to-one correspondence in seal groove.
There is the guide surface for curved surface in above-mentioned pipe joint, on the end face of the body front end.
In above-mentioned pipe joint, the abutment face is plane, and gasket is arranged at the abutment face.
Compared with prior art, this pipe joint only includes single main structure, it is only necessary to cooperate nut, sealing element, close
The pipe fitting connection at scene can be realized in the standard components such as packing, and structure is relatively simple, and processing is more convenient, and processing cost is low.
