Technical field
The utility model relates to cooling kapillary flow checkout equipment, specifically a kind of digital kapillary flow testing device.
Background technology
The kapillary of refrigerator, refrigerator is the restriction device that is used for regulating refrigerant flow and pressure.Its flow size, the quality of direct relation refrigeration, so produce, in the test, extensively adopt the capillary flow tester to the kapillary in the refrigeration plants such as air-conditioning, refrigerator, refrigerator detect, verification.
Traditional capillary flow tester, be to adopt volumetric displacement meter as measuring instrument, because of it is subjected to environment temperature, influence of atmosphere pressure, the error of the kapillary flow of surveying is sometimes even above 10%, adopting the resulting result of this method, mainly is that the kapillary flow is done a reference.Simultaneously, kapillary to be measured inside sometimes has impurity or attachment etc., can hinder airflow, obviously also influences measurement result.
In addition, existing web member device capillaceous to be measured, the employing flexible pipe that has directly connects, and this pipe repeatedly can deform in the use, thereby causes gas to leak, the accuracy that influence is measured; Have loading and unloading process capillaceous in, need be by instrument fixed capillary such as spanners, it is very inconvenient to operate.
Summary of the invention
The object of the present invention is to provide a kind of digital kapillary flow testing device, to remedy the deficiency of prior art.
The utility model comprises and N
2The total air valve that the source links to each other and with its in turn pipeline link to each other be positioned at tensimeter, reduction valve, precision pressure gauge on the panel, and the solenoid valve of controlling plumbing fixtures is at interior control device, with the mouth that connects that links to each other with flow testing device, it is characterized in that flow testing device connects a solenoid valve again, and flow testing device is the mass flowmeter that is connected with digital displaying meter.
Consider kapillary washed and the needs that can carry out precision measurement that be provided with one again specially at precision pressure gauge with connect flusher between the mouth, this device is formed by connecting by the solenoid valve of cleaning agent tank and both sides thereof.So that, carry out flow rate test then to kapillary flushing in advance.
Consider again and lay kapillary fast, a kind of mouth that connects fast capillaceous of specialized designs.This connects mouth and is made up of copper cushion block, rubber blanket and four parts of connector of concave surface handgrip, an end.The cavity of putting rubber blanket and copper cushion block is arranged in connector one end, rely on the external thread of this end outside and the screw-internal thread fit of handgrip.The concave surface of copper cushion block contacts with rubber blanket, and the another side of copper cushion block contacts with the inner face of handgrip.This connects mouth inserts kapillary fast, and cooperates closely, avoids gas to leak, with realize the kapillary flow fast, accurately measure and measuring process convenient and simple.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is a basic structure synoptic diagram of the present utility model.
Fig. 2 is connected with the structural representation that connects mouth fast capillaceous.
Fig. 3 is for connecing the STRUCTURE DECOMPOSITION synoptic diagram of mouth fast.
Wherein, 1 total air valve, 2 tensimeters, 3 reduction valve, 4 precision pressure gauges, 5 solenoid valves, 6 flow testing devices, 7 digital displaying meters, 8 cleaning agent tanks, 9 connect mouth, 10 kapillaries, 11 handgrips, 12 copper cushion blocks, 13 rubber, 14 connectors
Embodiment
As Fig. 1, the present invention includes and N
2The total air valve 1 that the source links to each other, and be positioned at tensimeter 2 on the panel with total air valve 1 links to each other in turn, reduction valve 3, precision pressure gauge 4, and the solenoid valve 5 of controlling plumbing fixtures interior control device with link to each other with flow testing device 6 connect mouth 9, it is characterized in that flow testing device 6 connects a solenoid valve 5 again, and flow testing device 6 is the mass flowmeters that are connected with digital displaying meter 7, test result is not subjected to the influence of scene temperature and change of atmospheric pressure.
Consider kapillary washed and the needs that can carry out precision measurement that be provided with one again specially at precision pressure gauge with connect flusher between the mouth, this flusher is formed by connecting by the solenoid valve 5 of cleaning agent tank 8 and both sides thereof.This flusher walks abreast with the solenoid valve 5 at flow testing device and two ends thereof and is communicated with.In the time of need carrying out capillary douche, two solenoid valves 5 of quality of connection flowmeter are controlled and cut out, two solenoid valves 5 that connect the irrigation jar are simultaneously opened, otherwise, after flushing finishes, two closed electromagnetic valves that connect cleaning agent tank, two solenoid valves 5 of quality of connection flowmeter are opened simultaneously, directly kapillary are carried out flow measurement.
Consider and lay kapillary fast and guarantee that gas does not have leakage, specialized designs the mouth 9 that connects fast capillaceous, this connects mouth and is made up of copper cushion block 12, rubber blanket 13 and 14 4 parts of connector of concave surface handgrip 11, an end, and the cavity of putting rubber blanket 13 and copper cushion block 12 is arranged in the end of connector 14, rely on the external thread of this end outside and the screw-internal thread fit of handgrip 11, the concave surface of copper cushion block 12 contacts with rubber blanket 13, and the another side of copper cushion block 12 contacts with the inner face of handgrip 11.
The above-mentioned mouth 9 that connects can dispose the rubber blanket 13 and the copper cushion block 12 in interdependent aperture according to the external diameter of kapillary 10, and the internal diameter of the internal diameter of copper cushion block 12, rubber blanket 13 is more bigger than the external diameter of kapillary 10, so that kapillary 10 is inserted in the rubber blanket 13 than more smoothly; Rubber is lined with certain elasticity, and copper cushion block is processed into matrix near an end of rubber blanket.Because thread pitch is bigger, only need rotary handle 11 in less angular range, can make concave surface one end of copper cushion block 12 compress rubber blanket 13, kapillary is closely surrounded, closely contact with the internal diameter of connector 14 simultaneously.Thereby prevent that the gas in the measuring process from leaking, and guaranteed the accuracy of measuring.
N when certain pressure
2By flow testing device 6, connect mouth 9 and kapillary 10, can on digital displaying meter 7, demonstrate by N capillaceous
2Flow.Usually the test pressure of setting is generally in the 0.2MPa-1.0MPa scope.
The utility model of constructing thus, measurement result is accurate, test process is simple, quick, good airproof performance, also can select to wash kapillary.
