Embodiment
The integral joint device fast and safely of a kind of stainless steel corrugated flexible hose as shown in Figures 1 to 3, comprises joint 8, nut 3 that screw thread is arranged on described joint 8 one end.The tip inside of described joint 8 is provided with the first groove 9, and the outer side wall of described nut 3 is provided with second groove 10 corresponding with described first groove 9.Also comprise overall the first C-shaped snap ring 11, described first snap ring 11 has elasticity in its radial direction, can shrink and open, external diameter due to the first snap ring 11 is greater than the external diameter of the first groove 9, and its internal diameter is less than the external diameter of the second groove 10, therefore, the first snap ring 11 can be connected in the first groove 9 and the second groove 10 simultaneously.
When installing the first snap ring 11, first tightened up by the first snap ring 11, and be placed in the first groove 9, the first snap ring 11 opens automatically.Then by nut 3 precession joint 8, when the front end of nut 3 abuts with the first snap ring 11, the chamfer surface of nut 3 front end can strut the first snap ring 11, and nut 3 continues precession, and the first snap ring 11, under the stop of the first groove 9, cannot advance.When nut 3 move to the second groove 10 overlap with the first snap ring 11 time, the first snap ring 11, under the contractile force of himself, snaps in the second groove 10.Because the end face of the first groove 9 and the second groove 10 does not all arrange plane of inclination, therefore, regardless of nut 3 precession or back-out joint 8, first snap ring 11 all cannot be pushed generation deformation, can not deviate from the first groove 9 or the second groove 10, therefore, nut 3 just cannot be removed with joint 8.
The present invention also comprises the second snap ring 6 that radial cross section is C-shaped, can stretch in radial direction, and the outer side wall of described second snap ring 6 is provided with the first plane of inclination 61 distributed vertically, and its one end open is provided with the lip part 62 extended to the second snap ring 6 central direction; Described second snap ring 6 is set between bellows 1 and described nut 3, and one end of its larger caliber is connected on the madial wall of described joint 8; Lip part 62 is arranged on more small-bore one end of the second snap ring 6.
Fitting operation of the present invention is as follows, first the first snap ring 11 is connected to the first groove 9 being positioned at joint 8, operating procedure is described above, then be sleeved on outside bellows 1 after successively the second snap ring 6, first seal ring 7, nut 3, joint 8 etc. being assembled according to set order, then nut 3 and joint 8 screwed.First snap ring 11, under the dragging of nut 3, outwards opens automatically, until the first snap ring 11 snaps in the second groove 10.Second snap ring 6, under the promotion of nut 3, shrinks automatically to the inside, in the wave groove that lip part 62 is snapped on the outer side wall of bellows 1, thus prevents bellows 1 from deviating from, and can also play the effect of sealing.
In order to ensure sealing of the present invention, the present invention also comprises the first seal ring 7 be set between described bellows 1 and described second snap ring 6, one end of described first seal ring 7 is connected on the madial wall of described joint 8, and the other end is connected on described lip part 62.When nut 3 screws installation with joint 8, the first plane of inclination 61 of the second snap ring 6 is subject to the thrust of axis from nut 3 and radial direction, and this radial thrust forces the second snap ring 6 to shrink to the inside, and lip part 62 is snapped on the outer side wall of bellows 1.This end thrust forces the second snap ring 6 to move radially, the end of the second snap ring 6 is made to insert the draw-in groove 81 be positioned on the madial wall of described joint 8, and this draw-in groove 81 is between the second snap ring 6 and the first seal ring 7, like this, shrink when the second snap ring 6 and snap in after in draw-in groove 81, certain seal action can be played, isolated the space between joint 8 inside and outside.
In addition, be provided with the second plane of inclination 63 abutted with described first seal ring 7 at the madial wall of described second snap ring 6, described second plane of inclination 63 is identical with the true dip direction of described first plane of inclination 61.Pass through this set, the active force of the second snap ring 6 to the first seal ring 7 is made also to form a radial thrust and end thrust, this radial thrust forces the first seal ring 7 to clamp bellows 1, this end thrust forces the madial wall close contact of the first seal ring 7 and joint 8, thus strengthens the sealing between joint 8 and bellows 1.
In order to improve the installation convenience of piecing devices and bellows 1, outside nut 3, be set with limited ring 12, can control the precession distance of nut 3 and joint 8 like this, the second snap ring 6 does not shrink completely, bellows 1 just can insert in joint 8 easily, can not be subject to the stop of lip part 62.After bellows 1 insertion puts in place, limited ring 12 is removed by operator, and then nut 3 and joint 8 are screwed, the second snap ring 6 is just compressed, and then makes lip part 62 snap in bellows 1.By above-mentioned design, no matter be the Pipe installing being provided with notch with threaded pipe 1 or other surface, the integrated type fitting operation of piecing devices can both be realized.
In one of them embodiment of the present invention, the end face that described nut 3 contacts with the second snap ring 6 can be arranged to plane of inclination, the end face that described first seal ring 7 contacts with the second snap ring 6 also can be arranged to plane of inclination, make nut 3 to the active force of the second snap ring 6 like this, and the active force of the second snap ring 6 to the first seal ring 7 is more stable.
Further, the outer side wall of described nut 3 is provided with the boss 31 extended laterally, between a side end of described joint 8 and described boss 31, is provided with the second seal ring 5.The 3rd seal ring 4 is provided with between the madial wall and the outer side wall of described bellows 1 of described nut 3.Like this, by the effect of the second seal ring 5 and the 3rd seal ring 4, respectively the assemblage gap of nut 3 with the assemblage gap of joint 8 and the bellows 1 of nut 3 is all sealed.When the second seal ring 5 is by compressive strain, can prove that nut 3 is closely with the installation of joint 8.
After verifying that nut 3 and joint 8 are installed, the tightness of joint 8 inside, on described nut 3, between described 3rd seal ring 4 and the first seal ring 7, be provided with the through hole 32 of through nut 3 sidewall, through hole 32 can external detection facility, when detection facility detects pressure change, prove to leak gas between joint 8 and bellows 1.
In order to protect bellows 1, the outside of described bellows 1 is provided with clad 2, and described lip part 62, between the port of described clad 2 and the port of described bellows 1, makes lip part 62 can wave groove on bellows 1 outer wall described in clamping.
Above-described embodiment is the mode that the present invention uses in gas pipeline, and the present invention is also applicable in waterway pipe, as shown in Figure 4.In view of the use in gas pipeline; need higher safety coefficient; have employed multi-sealed protection and monitoring of structures; and in waterway pipe; only need guarantee water-tight; therefore; relative to above-mentioned embodiment in gas pipeline; the structure of the embodiment in waterway pipe decreases clad 2, the 3rd seal ring 4, second seal ring 5 and through hole 32; clad 2 protects bellows 1 can not be cut damage easily; 3rd seal ring 4, second seal ring 5 improves the sealing of pipeline, and through hole 32 is for monitoring the sealing of joint 8.Although decrease said structure, the fitting operation for joint 8 there is no and is affected, integral installation, easy-to-operat.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technological scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
