Description
The utility model relates to a kind of portable fluoridize machine, is used to small-sized totally-enclosed refrigerating machinery to add fluorine Lyons and pressure testing and finding time indirectly.
At present, the general volume of fluoridize machine of import is all very huge, and it is all greatly too convenient to move and use, and price is also very expensive, and particularly they all do not have a kind of effective metering device, have influenced their result of use.If any a kind of Japanese fluoridize machine, there is not metering device at all, it grasps fluorine adding content by observing manometric variation, and precision is lower, also is difficult to grasp.Also have some fluoridize machines to be provided with the fluoridize hopper, but operate very loaded down with trivial details, they are according to the pairing specific volume of temperature at that time, the minimizing of inspection section internal volume and converted weight, this metering method is owing to be subjected to the influence of temperature and sight line deviation, and the conversion of will tabling look-up, so operation is difficult to accomplish rapidly accurately.
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and a kind of simple in structure, easy to operate, portable accurately rapidly fluoridize machine of metering is provided.
How introduce the purpose of this utility model below in conjunction with accompanying drawing realizes.
Fig. 1 is structural representation of the present utility model (in order to observe the structure of electronic scale 10, the outer cover 28 on its top has cutd open).
Fig. 2 is an operation principle schematic diagram of the present utility model.
Fig. 3 is circuit theory diagrams of the present utility model.
According to Figure 1 and Figure 2, top of the present utility model is provided with a freon cylinder 6, be full of the fluorine Lyons of freezing used in the bottle, its bottleneck is received fluoridize flexible pipe 18 by a liquid valve 8, the end of flexible pipe 18 is received pipeline 17 by hand-operated valve 3, pipeline 17 is provided with a joint 14 by hand-operated valve 4 later its ends, when whether the pipeline in the needs inspection refrigeration plant leaks gas, a nitrogen cylinder 23 can be linked to each other with joint 14. In pipeline 17 branches of hand-operated valve 4 fronts, also be provided with four-way connection 20, pick out three branch lines by this joint 20, the end of its three branch lines is respectively arranged with joint 13(and be used for connects hand-operated valve 21 and refrigeration plant 24), Pressure gauge 5(observes pressure condition), hand-operated valve 2 and vavuum pump 1(be for finding time). On shell 22, also be provided with in addition switch 15(" metering "-" finding time " switch) and switch 16(power switch) and handle 19. Unique distinction of the present utility model is also to be provided with a used electronic scale 10 of metering fluorine adding content, and the base of its freon cylinder 6 and support 7 thereof is arranged on the scale pan of electronic scale 10. Before refrigeration plant conveying fluorine Lyons, electronic scale 10 shows a gross weight (weight that comprises the annexes such as freon cylinder 6, support 7, flexible pipe 18), when importing a certain amount of fluorine Lyons to refrigeration plant, electronic scale 10 will show a difference, just can calculate the conveying capacity in fluorine Lyons by its difference. As: the gross weight that electronic scale shows before carrying is 700g, and electronic scale shows 600g when being transported to a certain moment, and this moment has been carried 100g fluorine Lyons, i.e. 700g-600g=100g to refrigeration plant in explanation so.
The utility model compared with prior art has lot of advantages. It simple in structure, volume is little, and is in light weight, cost is low, the fluoridize metering rapidly accurately, and is very easy to use, it be at present to refrigeration plant carry out fluoridize, pressure testing, the comparatively desirable instrument of finding time.
Be embodiment of the present utility model below.
Vavuum pump 1 of the present utility model is selected the 2xz0.25 rotary-vane vaccum pump for use, and motor 25 is selected the single-phase 220V 120W of JZ6324(for use) motor of model, the two is installed in the both sides of complete machine pedestal 26, is provided with shell 22 above.The top of pedestal 26 is provided with a handle 19 after by shell 22, is convenient to move complete machine.On the shell 22 of vavuum pump 1 and motor 25 joints, have a peep hole 27, the working order of being convenient to observe motor and vavuum pump.The electronic scale 10 of a DS-88A 2kg is set at the upper right quarter of shell 22, be provided with outer cover 28 on the top of electronic scale 10, position corresponding with the electronic scale liquid crystal display has reading demonstration hole 11 on it, and display lighting lamp 12 is equipped with on its side, is convenient to observe the demonstration reading of electronic scale.Freon cylinder 6 is selected R for use
22Or R
12Type 400g joins by lock ring 9 and support 7, and the lower end of three cradling pieces is welded on the iron plate base, and this base is placed on the scale pan of electronic scale 10.The bottleneck of freon cylinder 6 is equipped with liquid valve 8, and the fluoridize flexible pipe 18 that diameter is φ 10mm is received in its output.The end of flexible pipe 18 is connected to the hand-operated valve 3 that model is FS-1/4, is connected to φ 6/1T thereafter
3Pipeline 17, pipeline 17 is provided with a joint 14 by its ends after the hand-operated valve 4.Also be provided with four-way connection 20 in pipeline 17 branches of hand-operated valve 4 fronts, pick out three branch lines by this joint 20, the end of a branch line is provided with joint 13, and another branch line end is provided with a 76CMHg-16kg/cm
2Pressure gauge 5, also have a branch line end to be connected to hand-operated valve 2, can receive vavuum pump 1 by this valve." metering "-" finding time " switch 15 and power switch 16 also are installed on shell 22 in addition.
Introduce using method of the present utility model below respectively:
1. pressure testing indirectly: purpose is in order to check whether the pipeline in the refrigeration plant 24 leaks gas.One nitrogen cylinder 23 is inserted on the joint 14, close hand-operated valve 2,3, open hand-operated valve 21,4, slowly open the valve of nitrogen cylinder 23, observe Pressure gauge 5 simultaneously and promptly close nitrogen cylinder 23, if Pressure gauge 5 is stablized and constantly illustrated that promptly the pipeline in the refrigeration plant 24 is air tight to setting (being generally 10kg).
2. vacuumize: do not exist because of not allowing other gas in the pipeline of refrigeration plant 24, otherwise do not freeze, so will find time.During operation, close hand-operated valve 3,4, open hand-operated valve 21,2 and vavuum pump 1, the gas in the equipment is discharged in the atmosphere by vavuum pump 1, (by observing on the Pressure gauge 5) closes hand-operated valve 2 after being extracted into the specified vacuum degree, so just air in the equipment or nitrogen has been rejected to the outside.
3. fluoridize: fluoridize must carry out under the specified vacuum state, closes hand-operated valve 21,4,2, opens liquid valve 8.Slowly open hand-operated valve 3, this moment, freon cylinder 6 interior fluorine at first were full of in hand-operated valve 21 pipeline 17 in the past, observe the demonstration of electronic scale 10 and remember its value this moment, slowly open hand-operated valve 21 then and allow fluorine enter in the pipeline of refrigeration plant 24, treat to close hand-operated valve 21 when electronic scale is shown to the difference of required fluorine adding content.For example: electronic scale is shown as 700g before opening valve 21, and electronic scale shows that difference is 580g when fluoridize 120g, i.e. the 700g-580g=120g(fluorine adding content).
