Description
Technical field
The invention belongs to the storage device technical field of compressed natural gas, a kind of big volume bottle formula gas storage well particularly is provided.
Background technique
Refueling mother station adopts the bushing type gas storage well mostly at present, the general pipe that 8～10 Φ 245mmx12mmx10000mm are all arranged is by thread bush and be installed together, 7～8 screw thread seams are generally all arranged, and thread bush and high especially to the straightness accuracy requirement of pipe, because the screw thread junction plane is many, after use after a while, threaded connection place through the sleeve pipe of being everlasting, leakage phenomenon appears, very unreliable, along with succeeding in developing of Φ 720mm seamless large-diameter pipes and succeeding in developing of Φ 720mm major diameter spinning machine, my company has developed maximum in the world big volume bottle formula gas storage well, has safe and reliable, the characteristics that gas-storing capacity is big.
Summary of the invention
The purpose of this utility model is to provide a kind of big volume bottle formula gas storage well, and it is little to have overcome existing gas storage well volume, easily the drawback of leaking.The largest diameter 720mm of gas storage well, maximum volume can reach 4200L.
The present invention solves the technological scheme that its technical problem takes:
But the utility model comprises down end plug, O type circle, K type back-up ring, bottle, upper end plug, to silk, air inlet ball valve, inner drain pipe, blowdown joint, blowdown valve, the ball valve of giving vent to anger, combination safety installations, flared type tuning end union elbow, blow-down pipe, ball valve, elbow, safety valve; Following end plug 1 and upper end plug 5 are connected on the bottle 4 by O type circle 2 and K type back-up ring 3, and during operation, O type circle 2 and K type back-up ring 3 play the effect of double seal, and first pair of silk 6 is connected with air inlet ball valve 7, carries out the operation of air inlet.Second pair of silk 11 is connected the operation of giving vent to anger with the ball valve 12 of giving vent to anger.Blowdown joint 9 is connected with the inner drain pipe 8 of gas cylinder, is connected with the outer blowdown valve 10 of gas cylinder simultaneously, carries out the blowdown operation.For guaranteeing the safety of big volume bottle formula gas storage well, blowdown joint 9 connects successively by the 3rd pair of silk 16, ball valve 17, elbow 18, safety valve 19, but connect combination safety installations 13, flared type tuning end union elbow 14 and blow-down pipe 15 successively in the upper end of bottle, combination safety installations 13 is rupture disk and low melting alloy composite structure, safe and reliable, blowdown joint 9 can be not quick-fried by mistake.When detonating, passes through by safety installations blow-down pipe emptying, more guaranteed the safety of gas cylinder, because big capacity high pressure gas seamless gas cylinder is not only diameter big (be at present maximum diameter 720mm) in the world, and length has also reached the limit (12190mm), so combination safety installations 13 and safety valve 19 are installed respectively on the top of gas cylinder, bottle 4 is by seamless steel pipe two ends rotary press modelling, and the bottleneck straight section is processed into the internal and external threads structure, is connected with following end plug 1 with upper end plug 5.Promptly satisfy the needs of operation, also can guarantee the safety of gas cylinder under any state.
Big capacity high pressure gas seamless gas cylinder provided by the invention 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, on the top of big capacity high pressure seamless gas cylinder combination safety installations 13 and safety valve 19 are installed respectively, have promptly been satisfied the needs of operation, also can guarantee safety at gas cylinder under the super high pressure accident state, under the 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 a big volume bottle formula gas storage well structural front view of the present utility model.Wherein, following end plug 1, O type circle 2, K type back-up ring 3, bottle 4, upper end plug 5, the first pair of silk 6, air inlet ball valve 7, inner drain pipe 8, blowdown joint 9,10, the second pairs of silks 11 of blowdown valve, the ball valve 12 of giving vent to anger.
Fig. 2 is a big volume bottle formula gas storage well structure left view of the present utility model.Wherein, but combination safety installations 13, flared type tuning end union elbow 14, blow-down pipe 15, the 3rd pair of silk 16, ball valve 17, elbow 18, safety valve 19.
