Abstract
The utility model discloses a medical oxygen recovery and safety control device, which comprises a storage tank with liquid medical oxygen and a safety valve which is connected with the storage tank for emptying. The storage tank is also connected in parallel with a regulating valve. A pressure gauge is arranged between the storage tank and the regulating valve. The regulating valve is also connected with a buffer tank. When the pressure of oxygen in the storage tank is high, the oxygen can be emptied, can be also recovered to the buffer valve by the regulating valve and is favorable for being recovered and guaranteeing safety.
Description
Technical field
The utility model relates to a kind of gas concentration unit, particularly the device of a kind of recovery of medical oxygen and safety control.
Background technique
Generally, liquid medical oxygen all is to leave storage tank in.Along with the variation of temperature, gaseous pressure can raise in the storage tank, and when normally reaching the 0.8MPa left and right sides, storage tank annex safety valve meeting take-off is partly carried out emptying to gas phase and handled, thereby causes the waste of part medical oxygen.
Summary of the invention
The utility model is in order to overcome above-mentioned shortcoming, and providing a kind of can carry out auto-control to the storage tank gaseous pressure, stops the recovery of medical oxygen of emptying waste of medical oxygen and the device of safety control.
The technical solution of the utility model is: a kind of medical oxygen reclaims the device with safety control, comprise the storage tank of depositing liquid medical oxygen, be connected the safety valve in order to emptying with storage tank, another pipeline of storage tank is provided with pressure gauge, storage tank also is parallel with modulating valve, and modulating valve also is connected to knock out drum.
Be equipped with ball valve before and after described safety valve, modulating valve, the pressure gauge, its role is to: when modulating valve broke down, ball valve was closed, and valve is transferred in maintenance.
The utility model is regulated liquid oxygen storage tank internal pressure automatically by modulating valve, thereby modulating valve is along with the open degree of the variation regulating valve of storage tank internal pressure, guarantee that the storage tank internal pressure is in safety range, if it is too fast that pressure rises, surpass the regulation range of modulating valve, then safety valve meeting take-off, guarantee safety, full-automatic equipment is adopted in this practicality, and cost is low, and is safe.

Fig. 1 is the utility model structural representation;
Among the figure: 1, storage tank, 2, dashpot, 3, pressure gauge, 4, safety valve, 5, modulating valve, 6-12, ball valve, 13, knock out drum, 14, atmospheric valve, 15, pressure gauge, 16, safety valve.
Embodiment
Below, with reference to accompanying drawing each mode of execution of the present utility model being described, it is more obvious that the purpose of this utility model and effect will become.
Medical oxygen as shown in Figure 1 reclaims the device with safety control, comprise the storage tank 1 of depositing liquid medical oxygen, be connected safety valve 4 in order to emptying with storage tank 1, storage tank 1 another pipeline is provided with pressure gauge 3, storage tank 1 also is parallel with modulating valve 5, and modulating valve 5 also is connected to knock out drum 13, when the pressure of pressure gauge 3 demonstrations rises, modulating valve 5 is slowly opened, and pressure is released into dashpot 13.
Described safety valve 4, modulating valve 5, pressure gauge 3 front and back are equipped with ball valve, when modulating valve 5 breaks down, can close ball valve, the maintenance modulating valve, modulating valve 5 with the annexation of storage tank 1 is: also be provided with a pipeline and be connected to modulating valve 5 on safety valve 4 and pipeline that storage tank 1 is connected, this pipeline is located at the ball valve back segment, the safety valve leading portion.
Also be provided with the safety valve 16 of a dribbling valve pressure gauge 15 and a dribbling valve on the described dashpot 13, described dashpot below also is provided with atmospheric valve 14.
When pressure gauge 3 pressure changed to some extent, it fed back to modulating valve 5 by instrument signal, and modulating valve 5 is regulated open degree automatically, thereby pressure is discharged into knock out drum.If it is too fast that pressure gauge 3 pressure rise, modulating valve can't be regulated, and surpasses on the safety valve 4 to prescribe a time limit, and safety valve 4 is opened pressure release, guarantees safety.
Claims (2)
1. a medical oxygen reclaims the device with safety control, comprise the storage tank of depositing liquid medical oxygen, be connected the safety valve in order to emptying with storage tank, another pipeline of storage tank is provided with pressure gauge, it is characterized in that storage tank also is parallel with modulating valve, modulating valve also is connected to knock out drum.
2. medical oxygen as claimed in claim 1 reclaims the device with safety control, it is characterized in that being equipped with ball valve before and after described safety valve, modulating valve, the pressure gauge.
