る。Figure 1 is a diagram showing the structure of a conventional pipe joint, Figure 2 is a detailed diagram of a conventional ring for a pipe joint, and Figure 3 is a detailed diagram of a ring for a pipe joint that is a feature of this invention. 1a is a joint body, 1a is a pipe taper thread, 1b is a hexagonal portion, 1C is a groove portion, 1d is a chamfered portion, 1e is a through hole, 2 is a piping material, 3 is a ring, 3a is a slit, and 4 is a cap nut. Note that the same or equivalent parts in the figures are indicated by the same reference numerals.

Claims

[Scope of utility model registration request]

One side has a taper thread for pipes, the other side has a male thread into which a cap nut for fastening the piping material is screwed, and the inside of the male thread has a groove into which a resin piping material can be inserted and fitted. A fitting body having a chamfered part on the entire outer circumference of the groove, and a ring having an inner diameter slightly larger than the outer diameter of the piping material and having an R-shaped end surface relative to the outer diameter of the piping material. By threading and tightening the acid thread of the cap nut to the male thread of the joint body so as to wrap around the ring, the R-shaped portion of the ring comes into contact with the chamfered part of the joint body, and rust of the ring is prevented. In a piping joint configured to seal the fluid flowing within the piping material by applying pressure in the circumferential direction of the piping material, a slit of a predetermined width is provided at an arbitrary position around the ring. ,
A piping joint characterized in that the ring is largely deflected when the cap nut is fastened, so that even if the diameter of the piping material is slightly different, the piping joint can be reliably sealed.
