Embodiment

For the purpose, technological scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

With reference to Fig. 1; A kind of liquefied gas tank joint structure that provides for the utility model; Comprise angle valve 100; Said angle valve 100 has first termination 110, second termination 120 and the 3rd termination that is communicated with liquefied gas tank (not shown), switch valve 200 and reduction valve (not shown) respectively; Be provided with a quick access device (not going out among the figure) between said the 3rd termination and the reduction valve, said quick access device comprises rapid pipe joint 300 and rapid pipe joint seat (not shown), and said rapid pipe joint 300 comprises first joint 310 and second joint 320.In the present embodiment, said the 3rd termination is shaped on the angle valve 100 by first joint 310 and forms, and with

first termination

110 and 120 conductings of second termination of angle valve 100.The other end of first joint 310 is connected with an end of second joint 320, the other end of second joint 320 and detachable being tightly connected of said rapid pipe joint seat.Identical in the connection of said second joint 320 and rapid pipe joint seat and the existing technology, do not give unnecessary details here.In the utility model, first joint 310 is directly molded on the angle valve 100, has reduced part, reduced cost, and saved assembling procedure, the more standardization of joint, practicability and the interchangeability that also are used in liquefied gas tank simultaneously are stronger.

Particularly, please with reference to Fig. 2 and Fig. 4, Fig. 5, in the present embodiment, the end that first joint 310 is provided with first outside thread, 311, the second joints 320 is provided with the first internal thread (not shown) that cooperates with first outside thread 311.Adopt this mode that is threaded, be convenient to the disassemble or assemble between first joint 310 and second joint 320, promptly made things convenient for removably connecting between second joint 320 and the angle valve 100.

Particularly, with reference to Fig. 3, Fig. 4, in the present embodiment, second joint 320 comprises the connecting sleeve 321 of a hollow, said first internal thread is located on the end inwall of connecting sleeve 321, is arranged with first Sealing 322 on the other end inwall of connecting sleeve 321.Connecting sleeve 321 1 ends are connected with first joint 310 through internal thread, and the other end is connected with the rapid pipe joint seat, and first Sealing 322 is then guaranteed the tightness that is connected with the rapid pipe joint seat to prevent the leakage of liquid gas.In the present embodiment, first Sealing 322 adopts the rubber material manufacturings, and it be " O " shape seal ring, is provided with three, has guaranteed the reliability that seals.

Particularly; Please refer again to Fig. 3, Fig. 4; As an embodiment of the utility model, connecting sleeve 321 internal fixation are provided with second Sealing 323, a sheathed floating plug 324 in said second Sealing 323; Floating plug 324 sides offer vent 3241, are provided with first elastic component 325 between the floating plug 324 and first joint 310.After rapid pipe joint 300 and rapid pipe joint seat were in place, vent 3241 just can be switched on.Air pipe on the rapid pipe joint this moment seat will promote further compression first elastic component 325 of floating plug 324, and floating plug 324 is retreated, and vent 3241 shifts out from the hole and is switched on.When rapid pipe joint 300 separates with the rapid pipe joint seat, floating plug 324 resets, and vent 3241 is closed, and coal gas can not leak from rapid pipe joint 100, and reliability is good.Above-mentioned rapid pipe joint 300 is connected to existing technology with the installation of rapid pipe joint seat, does not remake here and gives unnecessary details.In the present embodiment, first elastic component 325 is preferably spring.

Further, please refer again to Fig. 4, as an embodiment of the utility model, first joint 310 is a bar hole with the intercommunicating pore 312 of angle valve 100, and a floating plug 324 and first joint 310 end in opposite directions convex with the limited part 3242 that can replace with the bar hole bottom plane.The width of bar hole stretches out from bar hole to prevent limited part 3242 less than the diameter of limited part 3242.Bar hole also can be suitable shapes such as long-round-shape, rectangle or ellipse.Limited part 3242 is used to limit the sliding distance of floating plug 324, and in actual use, if the sliding distance of floating plug 324 is long, it might break away from the 3rd Sealing 323 and cause and can not automatically reset, and then cause and can't seal.Through limited part 3242 and bar hole are set, avoid floating plug 324 from second Sealing 323, to skid off, structural reliability is good.

Further, with reference to Fig. 3, as an embodiment of the utility model, connecting sleeve 321 and the outer wall of first joint, 310 connecting ends are provided with two corresponding side cuts 3211.Be provided with and cut edge 3211, when dismounting second joint, special tools such as spanner can be stuck in 3211 places that cut edge just, avoid producing slide relative and can't not screw.

With reference to Fig. 3, Fig. 4, switch valve 200 comprises is located at the handle member 220 that the spool 210 that rotates in second termination 120 that is arranged at angle valve 100 is arranged in second termination 120 with rotation and can stirs spool 210.Particularly; Spool is 210 1 cylinders; One end of cylinder is embedded with salable first termination 110 and the 3rd termination is the 3rd Sealing 230 of first joint 310, and the other end of cylinder is threadedly connected in the endoporus of second termination 120, and cylinder is established a card 240 near card on the end face of said threaded end; The other end of card 240 is arranged on the handle member 220, and handle member 220 is stirred spool 210 through rotation card 220.

Particularly; Handle member 220 comprises knob 221, swing arm 222 and fixed base 223; Knob 221 is fixedly connected on an end of swing arm 222, and fixed base 223 is threadedly connected on second termination 120, and swing arm 222 rotates and is arranged in the fixed base 223; The other end of swing arm 222 is provided with the draw-in groove 2221 that can supply card 240 cards to establish, and is provided with the 4th Sealing 224 between swing arm 222 and the fixed base 223.The through hole 2211 that can supply swing arm 222 1 ends to stretch into is offered at knob 221 centers, and the end that swing arm 222 stretches into through hole 2211 is arranged with second elastic component 225, on second elastic component 225, presses to be provided with the fixed cover 226 that is threaded with swing arm 222.Through such design; Through the just rotation of may command spool 210 of operation knob 221; When spool 210 screws in second termination 120, be embedded with the 3rd Sealing 230 sealings first termination 110 on spool 210 end faces, and the sidewall of spool 210 seals the 3rd termination; Thereby sealing in the whole angle valve 100, gas is non-negotiable; When unscrewing turn-knob 221, knob 221 control spools 210 outwards move, thus spool 210 and first termination 110, the disconnection of the 3rd termination, angle valve 100 is opened, and gas can pass through, and above-mentioned this control structure is simple, and reliability is good, and good seal performance.

More than be merely the preferred embodiment of the utility model,, any modification of being done within all spirit at the utility model and the principle, be equal to and replace and improvement etc., all should be included within the protection domain of the utility model not in order to restriction the utility model.
