Description
Technical field
The utility model relates to a kind of testing tool, especially relates to a kind of air-conditioning filing provision sealing propertytest instrument.
Background technology
In automobile industry, in production run, often because whole-vehicle air-conditioner system or air-conditioning liquid filing provision exist to be leaked, cause annotating unsuccessfully.In filling process, Chang Yinwei can't judge there is leakage in which for whole-vehicle air-conditioner system or air-conditioning liquid filing provision, and causes normally producing.
The utility model content
The utility model has designed a kind of air-conditioning filing provision sealing propertytest instrument, and the technical matters of its solution is to judge whole-vehicle air-conditioner system or air-conditioning liquid filing provision existence leakage, and causes normally producing.
In order to solve the technical matters of above-mentioned existence, the utility model has adopted following scheme:
A kind of air-conditioning filing provision sealing propertytest instrument, it is characterized in that: comprise sebific duct (1), sebific duct (1) two ends connect respectively a metal tube, sebific duct (1) forms a confined space with two metal tubes, be provided with high pressure fill valve (3) on a metal tube, high pressure fill valve (3) is connected with the air-conditioning liquid high-pressure side filling gun head (7) of air-conditioning filing provision; Be provided with low pressure fill valve (5) on the another one metal tube, low pressure fill valve (5) is connected with air-conditioning liquid low pressure end filling gun head (6).
Further, sebific duct (1) two ends are connected with metal tube by a pipe collar (4) respectively.
Further, metal tube is aluminum pipe (1).
Further, the rubber tube that described sebific duct (1) is sandwich construction.
This air-conditioning filing provision sealing propertytest instrument has following beneficial effect:
(1) by air-conditioning filing provision sealing propertytest instrument, the sealing to the air-conditioning filing provision is detected the utility model, can show vacuum values according to the air-conditioning filing provision, judged the sealing of air-conditioning filing provision, handled easily also is convenient to the problem quick solution.
(2) the utility model also can carry out the judgement of air-conditioning filing provision vacuum capability in testing process.
The accompanying drawing explanation
Fig. 1: the structural representation of the utility model air-conditioning filing provision sealing propertytest instrument;
Fig. 2: the connection diagram of the utility model air-conditioning filing provision sealing propertytest instrument.
1-aluminum pipe; 2-sebific duct; 3-high pressure fill valve; 4-pipe collar; 5-low pressure fill valve; 6-air-conditioning liquid low pressure end filling gun head; 7-air-conditioning liquid high-pressure side filling gun head.
Embodiment
Below in conjunction with Fig. 1 and Fig. 2, the utility model is described further:
According to technique scheme, concrete steps are according to following enforcement:
1, get air-conditioning filing provision sealing propertytest instrument.As shown in Figure 1, comprise sebific duct 1, sebific duct 1 two ends connect respectively a metal tube, and sebific duct 1 and two metal tubes form a confined space, be provided with high pressure fill valve 3 on a metal tube, high pressure fill valve 3 is connected with the air-conditioning liquid high-pressure side filling gun head 7 of air-conditioning filing provision; Be provided with low pressure fill valve 5 on the another one metal tube, low pressure fill valve 5 is connected with air-conditioning liquid low pressure end filling gun head 6.Sebific duct 1 two ends are connected with metal tube by a pipe collar 4 respectively.Metal tube is aluminum pipe 1.The rubber tube that sebific duct 1 is sandwich construction.
2, according to structural representation, filling gun and sealing propertytest specific purpose tool are connected, high-low pressure filling gun head is connected with the high and low pressure fill valve on the detection specific purpose tool respectively, guarantees that equipment filling gun and sealing propertytest specific purpose tool are in clamped condition, as tool applications Fig. 2.
3, press filing provision and vacuumize button, vacuumized with vacuum leak and detect.The vacuum values that under synchronous recording, the air-conditioning filing provision shows, compare itself and theoretical value, also can make response curve and be judged.
According to vacuumizing principle, will set a 50s-60s pumpdown time, vacuum leak is set as the value of vacuumizing and vacuum leak that 60s-100s shows according to the air-conditioning filing provision detection time and detects vacuum values, the state that determining apparatus seals.
Criterion:
(1), if the value of vacuumizing is 0.5-1.0mbar, curve descends rapidly; Vacuum leak test vacuum values≤3.5mbar, tend towards stability, and sealing is qualified gently for curve.
(2), if vacuumize and descend slowly, when vacuum leak detects, curve increases comparatively rapidly, leaks.
Can solve by specific purpose tool of the present utility model the problem that air-conditioning filing provision sealing can't be judged fully; And easy to operate, be convenient to ordinary maintenance and safeguard.Also can use during the course this instrument to carry out the judgement of equipment vacuum capability.After maintenance of equipment, use this sealing propertytest instrument to be confirmed equipment state.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obvious realization of the present utility model is not subject to the restrictions described above; as long as the various improvement that adopted method design of the present utility model and technical scheme to carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all in protection domain of the present utility model.
