Technical field
The utility model relates to a kind of pipe fittings, and in particular to a kind of insert seal pipe fitting.
Background technique
Pipe fitting is the adapter of common fluid system, the connection type of pipe fitting to reach required sealing performance and
Structural strength.In the application of some plate pipes connection, due to being limited by structural condition, pipe fitting can only be from the side of thin plate
It is installed.
Especially for the inlet and outlet pipes connector of thin plate, it is connected to the fluid course region of thin plate, which is pressed from both sides by two layers
There is the thin plate of cavity to be formed.For inflation type or it is brazed soldering formula thin plate, the thickness of cavity namely the height very little of fluid course,
Usually only 3-10mm, pipe fitting and installation tool can only also be processed from unilateral side；Water pipe head can not be inserted into thin plate it is too deep with
Exempt to block fluid course or increases flow resistance；Thin plate only has through-hole, without flange or other in the junction with water pipe head
Support structure.These structural conditions bring very big difficulty for the installation of pipe fitting.
The connection of the inlet and outlet pipes connector of existing thin plate generallys use welding manner, by one layer of water pipe head insertion thin plate
In the nipple orifice accomplished fluently on thin plate, connected with soldering, argon arc welding or other welding methods.Due to pipeline and plate hole lack positioning and
Support, welding is extremely difficult, is easy to appear failure welding and causes to leak.Pipe on some specific positions such as sheet turnup is connect
The connection of head is difficult to adopt welding procedure since position is very compact and realizes piping connection and sealing.

Sealing ring between thin plate 1.
Pressure ring 31 is equipped with the toroidal cavity 311 for avoiding 22 position of pressing plate close to one end of sealing element.
2 material of cutting ferrule is metal or high molecule plastic.The material of sealing ring 4 is polytetrafluoroethylene (PTFE), graphite, rubber or other
Polymer composite.
Position limiting structure and sealing element have following embodiment:
Embodiment 1:
Such as Fig. 1~2, position limiting structure includes several stabilizer blades, and stabilizer blade end is equipped with outwardly directed for catching on through-hole week
The dog clutch 21 of 1 inner wall of thin plate enclosed, diameter of the outer diameter slightly larger than through-hole of dog clutch 21, stabilizer blade shrinkage deformation when being inserted into through-hole,
And flicked into cavity rear leg so that dog clutch 21 and 1 inner wall of thin plate cooperate in dog clutch 21, cooperation section Basolateral is convenient for leading
Enter the conical surface into through-hole, 21 upper surface of dog clutch is for the plane after being inserted into the cooperation of 1 inner wall of thin plate.
There is pressing plate 22, thin plate 1 is stuck between pressing plate 22 and dog clutch 21, pressing plate between the cooperation section of cutting ferrule 2 and external section
22 diameter is greater than the diameter of through-hole.
Sealing element is the sealing ring 4 covered outside pressing plate 22, and sealing ring 4 is pressed on thin plate 1 by pressure ring.
Embodiment 2:
Such as Fig. 3~4, position limiting structure is snap ring, and snap ring is equipped with the first external screw thread, and snap ring circumferentially offers several notches,
The snap ring 23 interior contract when being inserted into through-hole is threaded into, after the first external screw thread of snap ring 23 fully enters cavity, snap ring
23 the first external screw thread is stuck in thin plate.
The externally threaded outer diameter of the first of snap ring 23 is slightly larger than the diameter of through-hole, because having notch 231 on snap ring 23,
Snap ring 23 can shrinkage deformation, the process for being screwed down snap ring 23 is equivalent to snap ring 23 and carries out tapping to through-hole, the first of snap ring 23
Screw thread all submerges in thin plate 1 and in cavity, therefore is stuck after the screw-in through-hole of snap ring 23, does not fall out.
There is straight pipe, straight pipe a part is located in through-hole, and another part is out of through-hole between snap ring 23 and external section
It stretches out, sealing element is sealing ring 4 or the band covered outside straight pipe.
A kind of installation method of above-mentioned insert seal pipe fitting, comprising the following steps:
Step 1: through-hole cutting ferrule 2 being inserted on connected thin plate 1:
If position limiting structure is dog clutch 21, it is firmly pressed downward cutting ferrule 2, so that dog clutch 21 is deformed inwardly tightening insertion through-hole, inserts
Enter rear dog clutch 21 to rebound, locks the inner wall of 1 through-hole of thin plate；
If position limiting structure is snap ring 23, snap ring 23 is screwed in through-hole, until the first external screw thread on snap ring 23 is complete
Portion submerges thin plate 1 and in cavity；
Step 2: sealing element is set in outside, 1 top of thin plate of cutting ferrule 2；
Step 3: connector 3 being screwed down cutting ferrule 2, the pressure ring 31 of connector 3 compresses the sealing element of annular, forms sealing surface；
After the completion of step 3, outer rim and thin plate 1 along pressure ring 31 are welded, and welding form has been the spot welding of reinforcement effect
It connects or continuously welds.Due to not needing to form sealing surface between pressure ring 31 and thin plate 1, the effect of this step welding is not that progress is close
Envelope, but the intensity being connect for reinforced joint 3 with thin plate 1, therefore the requirement for welding procedure is fairly simple.Pressure ring 31 with
Welding between thin plate 1, which can make snap ring 23 shoot the threaded connection that 1 mode of thin plate is formed, to be loosened.
It should be appreciated that specific embodiment described above is only used for explaining the utility model, it is not used to limit this reality
With novel.By the utility model the obvious changes or variations extended out of spirit still in the utility model protection
Among range.
