Detailed description of the invention
A kind of corrugated pipe for gas Quick-mounting joint as shown in accompanying drawing 1 to 3, including joint 8, is threadably mounted at the nut 3 of described joint 8 one end and is inserted into the corrugated tube 1 in described nut 3。Also including the snap ring 6 that radial section is C-shaped, can stretch in radial direction, the lateral wall of described snap ring 6 is provided with the first axially distributed inclined plane 61, and its one end open is provided with the flange part 62 extended to snap ring 6 center position；Described snap ring 6 is set between described corrugated tube 1 and described nut 3, and one end of its larger caliber is connected on the medial wall of described joint 8；Flange part 62 is arranged on more small-bore one end of snap ring 6。
During installation, have only to directly insert the snap joint assembled with corrugated tube be connected, then nut 3 and joint 8 are screwed, snap ring 6 is under the promotion of nut 3, automatically shrink to the inside, making flange part 62 snap in the wave groove on the lateral wall of corrugated tube 1, thus preventing corrugated tube 1 from deviating from, better playing the effect of sealing。During dismounting, also simply by unscrewing nut 3, making nut 3 separate with joint 8, snap ring 6 resets under natural resiliency power effect, and automatically leaves corrugated tube 1, is damaged from part。
In order to ensure sealing of the present utility model, this utility model also includes the first sealing ring 7 being set between described corrugated tube 1 and described snap ring 6, one end of described first sealing ring 7 is connected on the medial wall of described joint 8, and the other end is connected on described flange part 62。When nut 3 screws installation with joint 8, the first inclined plane 61 of snap ring 6 is subject to the thrust axially and radially from nut 3, and this radial thrust forces snap ring 6 to shrink to the inside so that flange part 62 snaps on the lateral wall of corrugated tube 1。This axial thrust forces snap ring 6 to move radially, the draw-in groove 81 being positioned on the medial wall of described joint 8 is inserted in the end making snap ring 6, and this draw-in groove 81 is between snap ring 6 and the first sealing ring 7, so, when snap ring 6 shrinks and snaps in after in draw-in groove 81, certain sealing function can be played, isolated the space between joint 8 inside and outside。
It addition, be provided with the second inclined plane 63 abutted with described first sealing ring 7 in the medial wall of described snap ring 6, described second inclined plane 63 is identical with the incline direction of described first inclined plane 61。Pass through this set, make snap ring 6 that the active force of the first sealing ring 7 also be formed a radial thrust and axial thrust, this radial thrust forces the first sealing ring 7 to clamp corrugated tube 1, this axial thrust forces the medial wall of the first sealing ring 7 and joint 8 to be in close contact, thus the sealing strengthened between joint 8 and corrugated tube 1。
In one of them embodiment of the present utility model, the end face that described nut 3 contacts with snap ring 6 can be arranged to inclined plane, the end face that described first sealing ring 7 contacts with snap ring 6 can also be arranged to inclined plane, so make the nut 3 active force to snap ring 6, and snap ring 6 is more stable to the active force of the first sealing ring 7。
Further, the lateral wall of described nut 3 is provided with the boss 31 extended laterally, between a side end and the described boss 31 of described joint 8, is provided with the second sealing ring 5。It is provided with the 3rd sealing ring 4 between the medial wall and the lateral wall of described corrugated tube 1 of described nut 3。So, by the effect of the second sealing ring 5 and the 3rd sealing ring 4, respectively the assemblage gap of the assemblage gap of nut 3 and joint 8 and the corrugated tube 1 of nut 3 is all sealed。When the second sealing ring 5 is by compression, it is possible to the installation proving nut 3 and joint 8 is close。
After verifying that nut 3 is installed with joint 8, air-tightness within joint 8, on described nut 3, between described 3rd sealing ring 4 and the first sealing ring 7, it is provided with through the detection hole 32 of nut 3 sidewall, detection hole 32 can external detection equipment, when detecting equipment Inspection to air pressure change, it was demonstrated that leak gas between joint 8 and corrugated tube 1。
In order to protect corrugated tube 1, the outside of described corrugated tube 1 is provided with clad 2, and described flange part 62 is between the port of described clad 2 and the port of described corrugated tube 1 so that flange part 62 can wave groove on corrugated tube 1 outer wall described in clamping。
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; conceive according to the technical solution of the utility model and utility model thereof and be equal to replacement or change, all should be encompassed within protection domain of the present utility model。
