The multi-path oxygen filling system can be realized through following technical proposals: a high-pressure oxygen input pipeline is connected with at least two oxygen cylinder filling pipelines, and a safety valve is arranged between the high-pressure oxygen input pipeline and the oxygen cylinder filling pipelines; the oxygen cylinder filling pipeline consists of high-pressure pneumatic valve, a pressure sensor, a one-way valve, a hyperbaric oxygen meter, a hand stop valve and an oxygen cylinder, all of which are connected in sequence; the high-pressure pneumatic valve is connected with an electromagnetic valve which controls starting of the high-pressure pneumatic valve; the pressure sensor, the electromagnetic valve and a high-pressure alarm are connected with a master controller respectively. The invention can realize both manual operation mode and automatic operation mode to enable the multi-path oxygen filling system to be of simple operation, safety and reliability.
Description
Technical field
The present invention relates to the oxygen filling equipment field, more particularly, relate to a kind of multipath oxygen filling system of many group oxygen cylinders that can automatically switch.
Background technique
Can't satisfy each during field work and oxygen generating plant all be arranged with oxygen point, therefore the oxygen of oxygen cylinder need be provided, and the oxygen that adopts pressure swing adsorption method (PSA) to produce, it goes out the restriction that oxygen pressure is subjected to making oxygen, can not be higher than adsorptive pressure, also just directly filling is in oxygen cylinder, and therefore the oxygen that is made by the PSA method need be pressed the oxygen filling bottle with compressor and filling equipment.
Oxygen filling device in the market generally is made up of safety valve, high-pressure stop valve, pressure gauge, oxygenation jig, is manually-operable, requires slow in one's movementsly during operation, has the special messenger to guard, but owing to changing reasons such as untimely, has unsafe hidden danger.
At present the product that automaticallyes switch be mostly by high pressure to low voltage operated, promptly, when one group of oxygen supply finishes, automatically switch to another group oxygen supply when oxygen cylinder during as the oxygen source of Central oxygen-supply, the assurance oxygen supply is successive.And the oxygenation operation generally is the process that factory goes out product, because output is bigger, is mostly special messenger's manual operations.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, the multipath oxygen filling systems that provide a kind of energy to automatically switch many group oxygen cylinders.
Multipath oxygen filling system of the present invention is achieved by following technical proposals, and high pressure oxygen intake line connects at least two oxygen cylinder filling pipelines, between high pressure oxygen intake line and oxygen cylinder filling pipeline safety valve is set; Described oxygen cylinder filling pipeline is made of the high-pressure air operated valve, pressure transducer, one-way valve, hyperbaric oxygen table, hand stop valve, the oxygen cylinder that connect successively; High-pressure air operated valve is connected with the solenoid valve of its startup of control; Master controller is connected with pressure transducer, solenoid valve and high pressure alarm respectively.
The present invention has following beneficial effect: The present invention be directed to open-air multipath oxygen filling system of pressing the oxygen design, adopt following safety installations:
1. between high pressure oxygen intake line and oxygen cylinder filling pipeline safety valve is set, safety valve can guarantee that overpressure relief equipment works in the pressure range of safety.
2. in the oxygen cylinder filling pipeline one-way valve is set, one-way valve can guarantee that oxygen cylinder mesohigh gas does not reflux, thereby guarantees the filling proper functioning of many group oxygen cylinders.
3. the master controller and connected pressure transducer, solenoid valve and the high pressure alarm that are provided with of the present invention realized that many groups of automatic switchover, working staties are indicated and the function of malfunction alarms.
The present invention can realize manually and automatic two kinds of modes of operation, make it simple to operate and safe and reliable.
Description of drawings
Fig. 1 is a principle of the invention block diagram.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
High pressure oxygen intake line of the present invention connects at least two oxygen cylinder filling pipelines, between high pressure oxygen intake line and oxygen cylinder filling pipeline safety valve is set; Be that example describes in detail with 2 oxygen cylinder filling pipelines below: as shown in Figure 1, high pressure oxygen after the compression enters oxygen filling equipment by high pressure oxygen intake line 5, behind high-pressure safety valve 4, be divided into two groups of I, II by a tee union 3, and connect high-pressure air operated valve 16,26 respectively, pressure transducer 15,25, one-way valve 14,24, hyperbaric oxygen table 13,23, hand stop valve 12,22 backs are connected with oxygen cylinder 11,21; High-pressure air operated valve 16,26 is connected with the solenoid valve 17,27 of its startup of control respectively; Master controller 6 respectively with pressure transducer 15,25, solenoid valve 17,27 and high pressure alarm 7 connects.
Lowered in field environment is abominable, can't guarantee can implement manually-operable under the prerequisite of power supply.After will treating that the oxygenation gas cylinder connects, can choose one group of filling wantonly, often open high-pressure air operated valve owing to selected for use, open corresponding oxygen cylinder valve and hand stop valve, observe the pressure of hyperbaric oxygen table, filling is behind required pressure, close its oxygen cylinder valve and hand stop valve, change another group oxygen cylinder filling.
When implementing operation automatically, can be by master controller 6 control electromagnetic valve 27, close high-pressure air operated valve 26, thereby close the II group, organize first oxygenation by I, in the process of filling, master controller 6 detects the force value of high pressure sensors 15, reach default filling pressure after, master controller 6 control electromagnetic valve 17 are closed high-pressure air operated valve 16, open high-pressure air operated valve 26, switch to the oxygenation of II group.High pressure alarm 7 sends the acoustooptic alarm prompting and changes oxygen cylinder simultaneously.Reciprocal with this automatic cycle.
Embodiment recited above is described the preferred embodiment for the present invention; be not that design of the present invention and scope are limited; under the prerequisite that does not break away from design philosophy of the present invention; common engineers and technicians make technological scheme of the present invention in related domain various distortion and improvement all should belong to protection scope of the present invention.
