Abstract

Technique is filled the invention discloses a kind of oxygen cylinder, liquid oxygen is filled with through tank car in cryogenic liquid tank, liquid oxygen in storage tank is pumped into gasifier through cryogenic liquid pump again, the oxygen gasified confluence that is compressed in gasifier is finally filled into row again, in filling to the oxygen cylinder for examining qualification, the process equipment of the present invention is easy for installation, easy to operate, safety, it is needed, and the process operation expense is low suitable for all kinds of large, medium and small production-scale producers of type, electricity consumption is few, productivity effect is high, operating personnel are few, and production cost is low, save expenses of labour spending.

Description

A kind of oxygen cylinder fills technique
Technical field
The present invention relates to gas filling field, more particularly to a kind of oxygen cylinder fills technique.
Background technology
At present, filling for oxygen is by the way of directly filling, and fills that technique is more complicated and there are some security risks.
Invention content
It is easy to operate and safe and effective the purpose of the present invention is to provide a kind of technique that fills of oxygen cylinder.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of oxygen cylinder fills technique, includes the following steps：
(1) open gas cylinder on cylinder valve, check connecting portion whether gas leakage；After passed examination, gas cylinder push-in is filled into remittance In stream row, and connect inflated hose；
(2) liquid oxygen is filled with through tank car in cryogenic liquid tank, starts cryogenic liquid pump, liquid oxygen is pumped into gasifier In, the rotational speed regulation of cryogenic liquid pump should match with filled gas cylinder quantity, and the flow that fills of gas cylinder is not greater than 8m3/ h, Ensure that the time that fills of every exhaust bottle is no less than 30 minutes；
(3) gas cylinder falls the air in bus-bar with replacement of oxygen first before filling, and the pressure of manifold to be filled is higher than gas During bottle residual compression, the air intake valve for the row of filling slowly is opened, gas enters gas cylinder；
(4) since inflation, the situation of change of pressure is observed at any time, is checked respectively for when pressure rises to 7MPa and 10MPa The temperature variations of bottle and cylinder valve junction whether gas leakage；
(5) when each exhaust bottle is full of, another inflatable and exhaust main valve is slightly opened before inflation main valve is closed, is turned off Then the inflation main valve being full of slowly opens another inflatable and exhaust main valve in time, start filling for another exhaust bottle；
(6) gas cylinder valve having been filled with is closed, by the gas cylinder of the pressure recovery in bus-bar to another row, discharges pipe Overbottom pressure in road, unloads gas cylinder from the row of filling, by only being checked.
Beneficial effects of the present invention：The process equipment of the present invention is easy for installation, easy to operate, safety, suitable for it is all kinds of it is big, Medium and small production-scale producer needs, and the process operation expense is low, and electricity consumption is few, and productivity effect is high, and operating personnel are few, raw Produce at low cost, saving expenses of labour spending.
Specific embodiment
With reference to specific embodiment, the present invention will be further described.

(3) gas cylinder falls the air in bus-bar with replacement of oxygen first before filling, and the pressure of manifold to be filled is higher than gas During bottle residual compression, the air intake valve for the row of filling slowly is opened, gas enters gas cylinder；
(4) since inflation, the situation of change of pressure is observed at any time, is checked respectively for when pressure rises to 7MPa and 10MPa The temperature variations of bottle and cylinder valve junction whether gas leakage；
(5) when each exhaust bottle is full of, another inflatable and exhaust main valve is slightly opened before inflation main valve is closed, is turned off Then the inflation main valve being full of slowly opens another inflatable and exhaust main valve in time, start filling for another exhaust bottle；
(6) gas cylinder valve having been filled with is closed, by the gas cylinder of the pressure recovery in bus-bar to another row, discharges pipe Overbottom pressure in road, unloads gas cylinder from the row of filling, by only being checked.
