Abstract
The utility model relates to a checking apparatus for an air conditioning accumulator. The checking apparatus is characterized in that the apparatus has two interfaces connected with ports of an accumulator; a power supply and a display device are connected in series between the two interfaces, wherein the power supply is a battery and the display device employs an indicating lamp. When being used, the checking apparatus is connected with plug-in components of the accumulator; if the pressure of the accumulator is insufficient, the display device carries out no indication; and if the pressure of the accumulator is normal, the display device sends an indication signal. The checking apparatus has advantages of simple structure, easy operation and low cost.
Description
Technical field
The utility model relates to a kind of to the verifying attachment in the air-conditioning system, particularly relates to a kind of verifying attachment of air conditioning liquid reservoir.
Background technology
Freon in the air-conditioning system, fluorine Lyons is the arch-criminal of depletion of the ozone layer, its stable chemical nature, do not have combustibility and toxicity, because their mean lifetimes in atmosphere reach centuries, so the major part of discharging is still stayed in the atmospheric envelope, wherein major part still rests on the troposphere, and sub-fraction rises up into stratosphere.At the freon of troposphere quite stable, after rising enters stratosphere, under certain meteorological condition, can under the effect of intense UV rays, be decomposed, the chlorine atom that decomposition discharges constantly destroys ozone molecule with ozone meeting chain-react.Studies show that a chlorine atom can destroy tens thousand of ozone molecules.
Therefore before air supply rate is installed, must check impermeability and the security of each parts.Wherein check the method for inspection of reservoir, normally in reservoir, be filled with quantitative constant-pressure nitrogen, come the detected pressures switch whether to work with multimeter again, this method inefficiency, easy flase drop, and damage easily multimeter.
The utility model content
The purpose of this utility model just provides a kind of verifying attachment of simple in structure, easy to operate, air conditioning liquid reservoir that cost is low.
Solution of the present utility model is such: have two interfaces that are connected with the reservoir port, be serially connected with power supply and display device between described two interfaces.
Further: described power supply is battery.
Further: described display device is to adopt pilot lamp.
The utility model has the advantages that simple in structure, easy to operate, cost is low.
Description of drawings
Structural representation when accompanying drawing 1 is reservoir air pressure deficiency.
Accompanying drawing 2 is reservoir air pressure structural representations when normal.
Connection status synoptic diagram when accompanying drawing 3 is the utility model use.
Accompanying drawing 4 is structural representations of the present utility model.
Embodiment
Following structure description of drawings embodiment of the present utility model.
As shown in Figure 4, present embodiment has two interfaces 9,10 that are connected with the reservoir port, is serially connected with power supply 8 and display device 7 between described two interfaces 9,10.Described power supply 8 is battery.Described display device 7 is to adopt pilot lamp, and contact 3 is enclosed within the sleeve pipe 4, and an end is leaned with diaphragm 5 by spring force and touches mutually, as shown in Figure 1.
Reservoir all can be filled with the nitrogen of 0.4 ± 0.1MPa at receiving inspection or before installing and using in reservoir.And respectively with stop up, blocking cap is the import and export shutoff of reservoir, prevents that nitrogen from discharging, then static placement is more than 48 hours.Doing so on the one hand is for airtight pressurize; On the other hand because the inertia of nitrogen, prevent also that therefore reservoir inside from damaging because of corrosion.
When leakage or deficiency occured nitrogen in the reservoir, namely the pressure of the 6 pairs of diaphragms 5 of nitrogen in the reservoir was inadequate, causes contact 3 not contact with plug-in unit 1, pressure switch shell 2, as shown in Figure 1; This moment interface 9 of the present utility model, 10 with after two plug-in units 1 are connected, because contact 3 is off-state, thereby display device 7 outages are not indicated, the defective that this reservoir exists leakage or pressure switch damage or other human factors to cause is described, therefore, this reservoir must be delivered quality department and rechecks.
When nitrogen was normal in the reservoir, namely the pressure of the 6 pairs of diaphragms 5 of nitrogen in the reservoir was enough, causes contact 3 and plug-in unit 1, pressure switch shell 2 to contact, as shown in Figure 2; This moment interface 9 of the present utility model, 10 with after two plug-in units 1 are connected, because contact 3 is on-state, thereby display device 7 electromotion pilot lamps are bright, send indicator signal, illustrate that this reservoir nonexistence can defective, can judge that performance is qualified maybe can install and use.
