Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment: (seeing Fig. 1, Fig. 2 and Fig. 3) is that atrium and the high-pressure seal ring 2 that has boss place between the left-hand side pipe 1 and right-hand side pipe 8 of desire connection therebetween.Clamping tapered sleeve 3,6 is provided with the dovetail inner conic hole.Three be two groups of claws 9 of one group be connected in same angles in the clamping tapered sleeve 3,6 respectively, with the circular arc tapering, evenly in the dovetail inner conic hole 17 of trisection, and be affixed on respectively on the outer wall of the pipe that connects with the radian desire.On the intrados of claw 9 tooth is arranged, claw 9 can be along the axial shrinkage of pipe, and is the same just like the structure of the claw of boring bench drill stick of tool head.(seeing Fig. 4, Fig. 5) left collar 4 be provided with clamping tapered sleeve 6 on the dovetail inner conic hole and claw 9 same angles, with circular arc tapering, the even cone 14 of trisection.(seeing Fig. 6, Fig. 7) right collar 5 be provided with clamping tapered sleeve 6 on the dovetail inner conic hole and claw 9 same angles, with circular arc tapering, the even cone 15 of trisection.(see figure 1) left side collar 4 is placed on the left-hand side pipe 1 and is pressed on the left outer surface of high-pressure seal ring 2.Right collar 5 is placed on the right-hand side pipe 8 and is pressed on the outer surface of high-pressure seal ring 2.The outer rim of (seeing Fig. 4, Fig. 6) left collar 4 be evenly equipped with projection 13 and with right collar 5 in groove 16 engagements, just like the fastening sealing configuration of high-pressure pot cover with the pot body.(see figure 1) clamping tapered sleeve 3 is fitted with left collar 4, right collar 5, left bolt overcoat 10 and Anti-rotating grommet 7.Two Anti-rotating grommets 7 place respectively between clamping tapered sleeve 3,6 and left bolt overcoat 10 and the right nut overcoat 12.The right nut overcoat 12 that (seeing Fig. 1, Figure 13, Figure 14, Figure 15, Figure 16) has the left bolt overcoat 10 of stiffening rib 21 on it and have stiffening rib 19 on it places on the clamping tapered sleeve 3,6 respectively and is spirally connected each other.Be shaped on attachment hole 18,20 respectively on left side bolt overcoat 10 and the right nut overcoat 12.Steel wire snap close 11 is connected with attachment hole 18,20.
The effect of high-pressure seal ring 2, the one, location, the one, sealing.
The left and right collar 4,5 that (see figure 1) high-pressure seal ring 2 is fastened is compressed, is closed in wherein.Be subjected to the compressing of high-pressure liquid, the opening on the high-pressure seal ring 2 opens automatically and is pressed on the pipe.Pressure is big more, pressure tight more, thus play the first layer Flexible Safety seal action of compensation automatically.
Stiffening rib on turn left side bolt overcoat 10 and the right nut overcoat 12 is spirally connected the two.In this process, clamping tapered sleeve 3,6 is subjected to squeezing of Anti-rotating grommet 7 moving, and when endwisely slipping of pipe tightened up, drive claw 9 also slides and tightens up, and pipe is linked together, thereby play the rigidity security seal effect that the second layer can be locked.
Steel wire snap close 11 is connected left bolt overcoat 10 with attachment hole on the right nut overcoat 12, can stop the loosening of this two overcoat of causing because of reasons such as vibrations effectively, thereby play the 3rd layer of rigidity security seal effect that can lock.
The utility model is used for connecting two pipes of desiring conveyance fluid therebetween.
