The 720-type large-capacity high-pressure gas seamless gas bottle comprises a front-ended safety device, a front-ended plug, an O-shaped ring, a K-type retainer ring, a bottle body, a rear-ended plug, a rear-ended combined safety device, a double-nipple, a gas inlet/outlet ball valve, an internal drainage pipe, a drainage joint and a drainage valve, wherein the front-ended plug (2) and the rear-ended plug (6) are connected on the bottle body (5) by the O-shaped ring (3) and the K-type retainer ring (4); the rear-ended combined safety device (7) is connected with the gas inlet/outlet ball valve (9) by the double-nipple (8); the drainage joint (11) is connected with the internal drainage pipe (10) in the gas bottle and is connected with the drainage valve (12) outside the gas bottle; and the front end and the rear end of the bottle body are connected with the front-ended safety device (1) and the rear-ended combined safety device (7) respectively. The 720-type large-capacity high-pressure gas seamless gas bottle has the advantages of overcoming the defects of small capacity and less loading capacity of the existing gas bottle. The maximum diameter of the gas bottle phi is 720mm, and the maximum capacity of the gas bottle is 4200L.
Description
Technical field
The utility model belongs to the storage and transportation apparatus technical field of compressed natural gas, and the big capacity high pressure gas of a kind of 720 types seamless gas cylinder particularly is provided.
Background technique
Rock gas has been used as fuel for motor vehicle more and more as a kind of clean energy resource.But has only 1～2 refueling mother station in each city, the whole tube nets in substation or the long high-pressure gas pipe trailer transportation at female station in the institute.So target that the useful load of trailer has become operator to pursue, promptly under the situation that is no more than standard GB 1589＜" road vehicle overall sizes, axle load and quality limit value " regulation, make the useful load of long tube car reach maximum value, we have invented maximum in the world at present pressurized gas seamless gas cylinder, with the trailer that this gas cylinder is made, can reach maximum in the world at present useful load.
Summary of the invention
The purpose of this utility model is to provide the big capacity high pressure gas of a kind of 720 types seamless gas cylinder, and it is little to have overcome existing gas cylinder volume, the drawback that useful load is few.Gas cylinder largest diameter 720mm, maximum volume can arrive 4200L.
The utility model comprises front end safety installations, preceding end plug, O type circle, K type back-up ring, bottle, back end plug, rear end combination safety installations, to silk, turnover balloon valve, inner drain pipe, blowdown joint, blowdown valve; Preceding end plug 2 and back end plug 6 are connected on the bottle 5 by O type circle 3 and K type back-up ring 4, during operation, O type circle 3 and K type back-up ring 4 play the effect of double seal, front end safety installations 1 is rupture disk and low melting alloy composite structure, rear end combination safety installations 7 is rupture disk and low melting alloy composite structure, safe and reliable, can be not quick-fried by mistake.Rear end combination safety installations 7 passes in and out the operation of gas by silk 8 is connected with turnover balloon valve 9.Blowdown joint 11 connects inner drain pipe 10 in bottle, connect blowdown valve 12 outside bottle, carries out the blowdown operation.Be connected with front end safety installations 1 and rear end combination safety installations 7 respectively in the front-end and back-end of bottle, more guaranteed the safety of gas cylinder, because it is big that big capacity high pressure gas seamless gas cylinder is not only diameter, and length has also reached the limit, so a front end peace device 1 and rear end combination safety installations 7 are installed respectively at the two ends of gas cylinder, promptly satisfy the needs of operation, also can guarantee the safety of gas cylinder under any state.
The big capacity high pressure gas seamless gas cylinder that the utility model provides has the following advantages:
1, adopts the direct rotary press modelling of seamless steel pipe, rounding off between bottle and the bottle head, discontinuous and the gauffer generation of non-structure, guaranteed the uniformity of stress distribution under the high pressure from structure, the stress of having avoided causing because of structure is discontinuous is concentrated and peak stress, has improved the fatigue performance of gas cylinder greatly.
2, front end safety installations 1 and rear end combination safety installations 7 are installed respectively at the two ends of big capacity high pressure seamless gas cylinder, promptly satisfied the needs of operation, also can guarantee safety at gas cylinder under the super high pressure accident state, under front end fire accident state and the rear end fire accident state.
3, inner drainage device is installed, can gets rid of the raffinate in the bottle at any time, can effectively prevent the stress corrosion that the hydrogen sulfide in the raffinate produces bottle.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of using on the trailer of the present utility model.Wherein, front end safety installations 1, preceding end plug 2, O type circle 3, K type back-up ring 4, bottle 5, back end plug 6, rear end combination safety installations 7, to silk 8, turnover balloon valve 9, inner drain pipe 10, blowdown joint 11, blowdown valve 12.
Embodiment
Fig. 1 is a kind of embodiment of the present invention.
As shown in Figure 1, the utility model comprise front end safety installations 1, preceding end plug 2, O type circle 3, K type back-up ring 4, bottle 5, back end plug 6, rear end combination safety installations 7, to silk 8, turnover balloon valve 9, inner drain pipe 10, blowdown joint 11, blowdown valve 12; Before end plug 2 and back end plug 6 by O type circle 3 and K type back-up ring 4, be connected on the bottle 5, during operation, O type circle 3 and K type back-up ring 4 play the effect of double seal, front end safety installations 1 is rupture disk and low melting alloy composite structure, rear end combination safety installations 7 is rupture disk and low melting alloy composite structure, safe and reliable, can be not quick-fried by mistake.Rear end combination safety installations 7 passes in and out the operation of gas by silk 8 is connected with turnover balloon valve 9.Blowdown joint 11 connects inner drain pipe 10 in bottle, connect blowdown valve 12 outside bottle, carries out the blowdown operation.Be connected with front end safety installations 1 and rear end combination safety installations 7 respectively in the front-end and back-end of bottle, more guaranteed the safety of gas cylinder, because it is big that big capacity high pressure gas seamless gas cylinder is not only diameter, and length has also reached the limit, so front end safety installations 1 and rear end combination safety installations 7 is installed respectively at the two ends of gas cylinder, promptly satisfy the needs of operation, also can guarantee the safety of gas cylinder under any state.
