Description
Technical field
The utility model relates to a kind of for filling the automatic evacuation filling machine of nitrogen hydrogen search gas.
Background technique
Mostly using refrigerant and helium as search gas before air-conditioning leak detection, the minimum rate of hunting leak of refrigerant is 1
×10-5Mbarl/s, precision are low.Filling refrigerant generally passes through refrigerant cylinder or transfer pipeline directly fills, not dedicated
Equipment；Helium can the rate of hunting leak can achieve 1 × 10-7Mbarl/s, precision is high, but helium is at high cost, while helium filling recycling is set
It is standby complicated, expensive, it is unfavorable for promoting the use of.The composition of nitrogen hydrogen mixing search gas is 95% nitrogen, 5% hydrogen (volume)
Composition also can achieve 1 × 10 as the search gas rate that can hunt leak-7Mbarl/s, and mixed gas does not have and fires, safety,
Gas source expense is low, discharges free from environmental pollution.
Hunting leak at present to air-conditioning needs first connecting line to vacuumize air-conditioning, then carries out vacuum detecting, and detection is closed
Pipeline being reconnected after lattice, search gas being filled with to air-conditioning, client hunts leak to air-conditioning, and leak detection, which finishes, again discharges gas, entirely
Process needs constantly to connect individual pipeline, and working efficiency is low, heavy workload.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of automatic evacuation filling machine, to reach automatic chemical conversion
Degree is high, and matching client's leak detection greatly improves the purpose of working efficiency.
In order to achieve the above objectives, the technical solution of the utility model is as follows：
One kind is automatic to evacuate filling machine, including evacuating gas-charging connection and passing through what pipeline was connect with evacuation gas-charging connection respectively
Evacuator, air charging system and exhaust apparatus, the evacuator include vacuum pump and evacuation solenoid valve, the air charging system packet
Gas cylinder, pressure reducer, filter and inflation solenoid valve are included, the exhaust apparatus includes exhaust-valve.
In above scheme, pressure sensor is set on the pipeline evacuated near gas-charging connection.
In above scheme, the exhaust-valve includes concatenated two exhaust-valves.
Through the above technical solutions, automatic evacuation filling machine provided by the utility model is integrated with evacuation, filling, discharge three
A process can control the course of work by pressure sensor and each solenoid valve, and automation degree is high, matching client's leak detection, significantly
Improve working efficiency.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described.
Fig. 1 is that one kind disclosed in the utility model embodiment evacuates filling machine schematic diagram automatically.
In figure, 1, evacuation gas-charging connection；2, vacuum pump；3, solenoid valve is evacuated；4, gas cylinder；5, pressure reducer；6, filter；7,
Inflate solenoid valve；8, exhaust-valve；9, pressure sensor.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
The utility model provides a kind of automatic evacuation filling machine, as shown in Figure 1, the automatic evacuation fills machine working efficiency
Height, it is easy to operate.
As shown in Figure 1, evacuating filling machine automatically, including evacuates gas-charging connection 1 and connect respectively by pipeline with inflation is evacuated
Evacuator, air charging system and the exhaust apparatus of first 1 connection, evacuator include vacuum pump 2 and evacuate solenoid valve 3, and inflation fills
It sets including gas cylinder 4, pressure reducer 5, filter 6 and inflation solenoid valve 7, exhaust apparatus includes concatenated two exhaust-valves 8.Evacuation is filled
Pressure sensor 9 is set on the pipeline near gas connector 1.
Client's air-conditioning is vacuumized first, nitrogen hydrogen mixeding gas is poured after vacuum is qualified, client hunts leak to air-conditioning, hunted leak
Finish and discharges nitrogen hydrogen.Pass through the detectable pressure for evacuating, inflating or being vented of pressure sensor 9.
Action specification：
1, it evacuates：Vacuum pump 2 starts, and evacuates solenoid valve 3 and opens, and inflation solenoid valve 7, exhaust-valve 8 are closed；
2, it fills：Vacuum pump 2 stops, and inflation solenoid valve 7 is opened, and evacuates solenoid valve 3, exhaust-valve 8 is closed；
3, it is vented：Vacuum pump 2 stops, row:Empty valve 8 is closed, and evacuates solenoid valve 3, inflation solenoid valve 7 is closed.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the present invention will not be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The widest scope consistent with features of novelty.
