Description
Technical field
The present invention relates to the technical field of memory of gas, specially a kind of high pressure gas packaging process.
Background technology
Currently, in terms of gas storage, when especially storing high pressure gas, generally use is that large-scale high pressure is stored up
Gas tank, structure are all relatively simple tank bodies, in actual use, probably since pressure is excessive when injecting gas every time
And cause the tank body of air accumulator that small deformation occurs, and it is permanent previous, holding vessel will be caused to scrap.Therefore, make in air accumulator
After long, usually it is required for that air accumulator is detected and is repaired, to find that the crackle occurred on tank body is gone forward side by side in time
Row repair, to ensure that gas will not escape.
Further, since high pressure tank is during use, it sometimes can be by extraneous impact, so that storage
Gas tank shakes, and the bolt shaken for a long time between the tank body and lid that may can realize connection high pressure tank goes out
It now loosens, once loosening occurs in bolt, gap is just will appear between tank body and lid, the gas in tank body is easy for effusion tank
Body also just reduces the preservation effect of gas, so, after the canned gas into high pressure tank, usually also need to cover
Nut on body is tightened again, ensures the close fastening between tank body and lid.However for large-scale high pressure tank,
Three groups or more of bolt usually can be all arranged in bolt on lid, and in this case, operating personnel just need to repeat at least three
Secondary tightens operation, moreover, because also having a certain distance, operating personnel often to complete once to tighten operation between each group bolt
Afterwards, it is also necessary to be moved at next group of bolt and be operated, entire rundown process elapsed time is also just long, entire gas
Pouring process is also just longer, and the filling efficiency of gas is also just relatively low, and how to improve the filling efficiency of high pressure gas also just becomes
One the technical issues of being badly in need of solving.
Invention content
The invention is intended to provide a kind of filling efficient high pressure gas packaging process.
The present invention provides base case：A kind of high pressure gas packaging process, includes the following steps；
The maintenance of S1, tank body：The entire outer wall of tank body is detected using the maintenance ladder being arranged on tank body；It is detecting
When intact to outer wall, carry out S2 and carry out S2 after being repaired to crackle at this when there is crackle on detecting outer wall；
S2, gas it is filling：The intake valve on the lid of gas storage device is opened, is passed through into tank body by intake valve
Gas observes the pressure gauge on lid, when the pointer of pressure gauge reaches specified atmospheric pressure value, closes intake valve；
The fastening of S3, tank body：One end of safety belt declines, and the safety belt other end is connected to around fixed pulley above lid
Sliding shoe rises, and the lead screw shaft being connected on sliding shoe rises, and rotates with the feed screw nut of lead screw shaft cooperation, connects with feed screw nut
The nut seat rotation connect, drives link rotation, the circle ring disk rotation of link lower end connection, on the buckling parts of cover edge with
The nut rotation of the screw thread engagement of circle ring disk periphery, is tightened on tank body and stretches out on the half of screw of lid buckling parts.
The operation principle of base case：When filling, tank body is overhauled first, testing staff is first to the lower part of tank body
It is detected, then when being overhauled to tank body top, it is contemplated that the height of tank body, service personnel can be by tank body at this time
On maintenance ladder can climb eminence, complete the detection to tank body top, can also complete to the entire outer wall of tank body
Detection, when having detected crackle, service personnel repairs crackle at this, ensures the intact of outer wall, and is detecting
During, with one end bandage service personnel of safety belt, play the role of a security protection.
After having detected, service personnel has been also at the top of tank body and has been detected at this time that is, at the lid of tank body upper end at this time
Personnel first open the intake valve on lid, and gas is passed through into tank body, and specified atmospheric pressure value is then reached in the pointer of pressure gauge
When, i.e., after the air pressure at this time in tank body has reached specified numerical value, intake valve is closed, the fill operations of gas are completed.
In view of gas storage device will appear shaking during use, therefore, complete gas it is filling after, need
The bolt of connection tank body and lid is carried out tightening reinforcing, testing staff gets off by maintenance ladder from lid at this time, due to
One end of safety belt is connected on testing staff, so during testing staff gets off from lid, safety belt
One end declines, and since the other end of safety belt is to bypass what fixed pulley was connect with sliding shoe, safety belt is another at this time
One end rises, and drives sliding shoe to rise, then by the cooperation of lead screw shaft and feed screw nut on sliding shoe, realize feed screw nut and
The rotation of nut seat, to drive circle ring disk to rotate, the nut rotation engaged with circle ring disk has also just been tightened on screw rod, real
Now to the tightening operation of bolt.
The advantageous effect of base case is：Compared with prior art, tank body is overhauled before gas filling, is avoided
Gas escapes the problem of tank body caused by tank body is cracked.And complete gas it is filling after, testing staff borrows
When helping maintenance ladder to get off from lid, sliding shoe is driven to rise, coordinate lead screw shaft and feed screw nut, realizes turning for circle ring disk
Dynamic, to which multiple nuts that driving is engaged with circle ring disk rotate simultaneously, that realizes bolt tightens reinforcing, ensure that tank body and lid
Between air-tightness, it is no longer necessary to testing staff tightens one by one, greatly shorten tighten bolt consumption time, to improve
Filling efficiency.
Preferred embodiment one：As the preferred of basic scheme, in S1, maintenance ladder can be along the annular being arranged in tank body circumferential direction
Slot slides.Advantageous effect：Sliding of the maintenance ladder in tank body circumferential direction is realized using the annular groove in tank body circumferential direction, you can realizes inspection
Repair personnel to outside tank body week to detection.
Preferred embodiment two：Preferably one it is preferred, in S3, circle ring disk is detachably connected on link.It is beneficial
Effect：In view of to the gas storage device of different size carry out gas it is filling when, the specification of lid would also vary from,
In order to ensure that circle ring disk is engaged with the nut on lid buckling parts, also just need circle ring disk that equally there is different specifications, therefore,
During gas filling, the circle ring disk that appropriate size is replaced according to the specification of lid is also just needed, so, by detachable
The mode of connection realizes that connection of the circle ring disk on link also ensures that circle ring disk can be replaced, and increases circle ring disk
Applicability.
Preferred embodiment three：Preferably two it is preferred, in S3, circle ring disk is bolted on link.Have
Beneficial effect：Bolted mode is selected to facilitate the dismounting of circle ring disk, stable connection.
Preferred embodiment four：As the preferred of basic scheme, in S3, fixed pulley is fixed on height-adjustable by locating rod
The top of supporting rack.Advantageous effect：In view of the height of the gas storage device of different size is different, therefore by fixed pulley
It is fixed on height-adjustable supporting rack, the height by adjusting supporting rack makes fixed pulley be adapted to the gas of different size
Body holding vessel, it is easy to operate.
Preferred embodiment five：Preferably four it is preferred, in S3, the supporting rods of supporting rack lower part both sides carries out tank body
Support.Advantageous effect：Supporting rod is supported tank body, avoids gas storage device and topples over.
