Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
Referring to fig. 1, the present embodiment discloses a high-pressure oxygen charging and discharging device, which comprises a main gas path 1, at least two sets of charging systems 2 connected in parallel and a control system (not shown in the figure); each filling system 2 comprises a high-pressure automatic valve 21, a plurality of first manual high-pressure valves 22, a plurality of oxygen cylinders 23 and a plurality of pressure sensors (not shown); the plurality of oxygen cylinders 23 are connected in parallel, the air inlet of each oxygen cylinder 23 is communicated with one end of a high-pressure automatic valve 21 after passing through a first manual high-pressure valve 22, and the other end of the high-pressure automatic valve 21 is communicated with the main air channel 1; each oxygen bottle 23 is provided with a pressure sensor; the control system is connected to both the high pressure automatic valve 21 and the pressure sensor.
In some embodiments, in order to prevent the system from uncontrollable faults, a safety valve 3 is installed on the main gas path 1, and when the pressure in the gas path is too high, the safety valve 3 is opened to release pressure, so that the safe use of the oxygen filling and discharging is ensured.
In some embodiments, a pressure controller 5 is provided on the main gas circuit 1. The pressure controller 5 detects, displays, alarms and outputs control signals to the pressure signals in the main gas path 1, so that the normal operation of the high-pressure oxygen filling and discharging is ensured. Further, a pressure gauge 4 is arranged on the main gas path 1. An operator can monitor the pressure in the main gas circuit 1 more accurately through the pressure gauge 4.
In some embodiments, the filling system 2 is further provided with a second manual high-pressure valve 24, the second manual high-pressure valve 24 is connected with the high-pressure automatic valve 21 in parallel, and when the high-pressure automatic valve 21 fails and is not communicated, the second manual high-pressure valve 24 can be manually opened for manual operation, so that the continuity of the filling process is ensured.
In the concrete implementation process, the filling pressure of the oxygen cylinder 23 can be set, but the limit pressure is not more than 30.5MPa, and the induction value of the pressure sensor of the filling system 2 is set on site according to the actual use condition, so that when the oxygen cylinder 23 reaches the set filling pressure, the pressure sensor transmits a signal to the control system, and the control system controls the opening or closing of the high-pressure automatic valve 21, so that the adjustment of the filling pressure is realized, the adaptability of the high-pressure oxygen filling and discharging is ensured, the adjustment is convenient, the control is simple, and the oxygen filling under the low-pressure working condition can be performed while the working condition of 30MPa of high pressure is satisfied.
In this embodiment, two sets of filling systems 2 and three oxygen cylinders 23 in each set of filling systems 2 are taken as examples for illustration:
in the specific implementation process of this embodiment, when the pressure sensor at the oxygen bottle 23 of one set of filling system 2 senses that the pressure value in the oxygen bottle 23 is lower than the set pressure (30 MPa), a signal is sent to the control system, the control system controls the high-pressure automatic valve 21 of the set of filling system 2 to be opened, and the high-pressure automatic valve 21 of the other set of filling system 2 is closed, at this time, the main gas circuit 1 is communicated with the oxygen bottle 23 to charge the oxygen bottle 23, and when the oxygen bottle 23 reaches the set pressure, the pressure sensor sends a signal to the control system, and the control system controls the high-pressure automatic valve 21 of the set of filling system 2 to be closed, so that the filling of the oxygen bottle 23 of this path is completed. When the oxygen bottle 23 in the other way of filling system 2 also reaches the set pressure, the control system closes the two ways of high-pressure automatic valves 21 according to the received signals of the two ways of pressure sensors, and stops the system. When the other path of oxygen bottle 23 is lower than the set pressure, the high-pressure automatic valve 21 of the path is opened, at the moment, the two paths are exchanged, the main gas path 1 inflates the oxygen bottle 23 of the path until the pressure value of the oxygen bottle 23 of the path reaches the set pressure, and the high-pressure automatic valve 21 is closed. The filling is performed cyclically and reciprocally in this way.
According to the embodiment, the high-pressure automatic valve 21, the first manual high-pressure valve 22, the pressure sensor and the control system are arranged, the pressure value in the oxygen bottle 23 is sensed by the pressure sensor and then sent to the control system, and then the control system controls the high-pressure automatic valve 21 to be opened or closed, so that the operation flow is simplified, the confirmation operation is not needed manually, the safety of operators is ensured, and meanwhile, the filling efficiency of the oxygen bottle 23 is improved.
Meanwhile, by arranging the safety valve 3, the pressure controller 5, the pressure gauge 4, the second manual high-pressure valve 24 and other devices, the safety of the whole high-pressure oxygen filling and discharging operation of the embodiment can be ensured, and the potential safety hazard is reduced.
