Abstract
The utility model relates to a liquid-conveying pipeline rapid sealing device which is composed of an inlet sleeve barrel and an outlet sleeve barrel. An inlet rotary ring and an inlet fixed ring are arranged in an inlet sleeve pipe, an outlet rotary ring and an outlet fixed ring are arranged in an outlet sleeve pipe, wherein a left flange disk and a right flange disk are respectively fixed on the end surfaces of the inlet and the outlet sleeve pipes and are fixedly connected through safety screw bolts. When a liquid-conveying pipeline needs an emergent seal, the inlet rotary ring and the outlet rotary ring simultaneously rotate an angle of 30 DEG under the action of a turning operating rod so that liquid can be instantly sealed, the outlet fixed ring is beaten by great impact force instantly generated by a piston impact force cylinder on the inlet fixed ring, the safety screw bolts are forced to be broken so that the left and the right parts of the sealing device are separated, and meanwhile, the inlet and the outlet rotary rings respectively and rapidly seal oil passages of the inlet and the outlet sleeve barrels. The utility model has the advantages of simple and compact structure, safe and reliable working, convenient operation, low cost, rapid pipeline sealing, no leakage, etc. Besides, the utility model can rapidly cut off and seal liquid-conveying pipelines in a very short time so that planes, ships, etc. can safely escape from dangerous spots.

Description of drawings
Fig. 1 is a structure cross-sectional schematic of the present utility model;
Among the figure: 1 inlet sleeve, 2 bulb pins, 3 dust boots, 4 import transposition joysticks, 5 flat keys, 6 left flange plates, 7 right flanges, 8 shear bolts, 9 binding bolts, 10 outlet transposition joysticks, 11 outlet sleeves, 12 outlet changes, the fixed ring of 13 outlets, 14 imports encircle surely, 15 piston impulse force cylinders, 16 springs, 17 import changes.
The specific embodiment
Below in conjunction with example structure of the present utility model and principle are described further.
The quick sealing device of a kind of liquid-transport pipe-line, as shown in Figure 1, this sealing device comprises that inlet sleeve 1, bulb pin 2, dust boot 3, import transposition joystick 4, left flange plate 6, right flange 7, shear bolt 8, outlet transposition joystick 10, outlet sleeve 11, outlet change 12, outlet encircle 13 surely, import encircles 14 surely, piston impulse force cylinder 15, import change 17.It divides import sleeve part and outlet sleeve part two parts, and two parts are located by flange, and connect fastening by 6 shear bolts 8.Reference for installation is respectively the interior circle of inlet sleeve 1 and outlet sleeve 11.Arrangement is: in the import sleeve part import change 17, import are housed and encircle 14 surely, 3 bulb pins 2 and spring 16 respectively are housed on import change both ends of the surface, import transposition joystick 4 screws in from the cylindrical opening position of inlet sleeve 1; Surely encircle in import and 12 piston impulse force cylinders 15 to be housed on 14 and 5,12 piston impulse forces of 1 flat key cylinder 15 is provided with fuel return hole, flat key 5 be embedded in import encircle surely 14 and inlet sleeve 1 between, spacing and fastening by left flange plate 6.In the outlet sleeve part outlet change 12 is housed, exports and encircle 13 surely.In outlet 6 bulb pins and spring and 1 peripheral hardware outlet transposition joystick 10 are housed equally in the change 12, outlet encircle surely 13 with outlet sleeve between be connected with 1 flat key; Same these parts are spacing and fastening by right flange 7.
Fast the installation process of sealing device is: the import change 17 that bulb pin, spring and seal ring will be housed is earlier packed in the inlet sleeve 1, and the circumferential openings from inlet sleeve 1 screws in import transposition joystick 4 in import change 17 from the outside again; The import that piston impulse force cylinder 15 and spring 14 will be housed then encircles 14 surely packs in the inlet sleeve 1, embeds flat key 5 again, adorns left flange plate 6 and spacing fixing with binding bolt 9 then, has so just finished the installation of import sleeve part.The sequence of erection of same outlet sleeve part is: the outlet change 12 that bulb pin, spring and seal ring will be housed is earlier packed in the outlet sleeve 11, again from the circumferential openings of outlet sleeve 11 from outer buttons inlet/outlet transposition joystick 10 in outlet change 12; The outlet that seal ring will be housed then encircles 13 surely packs in the outlet sleeve 11, embeds flat key again, loads onto right flange 7 and spacing fixing with binding bolt 9 afterwards, has so just finished the installation that exports the sleeve part.
The quick sealing device principle of work of liquid-transport pipe-line is: sealing device is serially connected with terminal promptly close mobile facility one side of liquid-transport pipe-line.During normal infusion, import change 17, import encircle 14 surely, outlet encircles 13 surely, 12 funnel type through holes of outlet change 12 directly communicate, and liquid is directly carried by sealing device under the basic unmodified situation of hydraulic radius keeping.When the urgent disjunction liquid-transport pipe-line of needs, rotate 2 transposition joysticks 4 and 10 simultaneously and rapidly, under the effect of this bar, import change 17,30 ° of angles are rotated in outlet change 12 simultaneously, and import encircle surely 14 and outlet encircle surely 13 since the effects of flat key 5 maintain static, so import change 17 directly encircles import surely 12 funnel type through holes of 14 and shuts, liquid moment is closed, surely encircle in import by 12 funnel type through hole hydraulic coupling snaps of import change 17 on 12 piston impulse force cylinders 15 of 14,15 moments of piston impulse force cylinder produce great impulse force, impact and encircle on 13 surely in outlet, this power is enough to make 6 shear bolts 8 to rupture simultaneously, thereby sealing device left and right sides two parts are separated; Meanwhile export change 12 and also shut the oil circuit of outlet sleeve 11 rapidly.After sealing device separated, ducted liquid relied on its endogenetic process to seal fully on import change and outlet change end face and by sealing arrangement.For making two transposition joystick manipulation laborsaving, at the two ends, the left and right sides of importing and exporting change 17 and 12 3 bulb pins are housed respectively respectively in addition, this two ends, two changes left and right sides hydraulic coupling also is a state of equilibrium simultaneously; Moreover the effect of dust boot 3 is to prevent that dust and impurity from entering sealing device inside.
