Description
Technical field
This utility model belongs to air conditioning for automobiles detection field, particularly relates to a kind of automobile air-conditioning refrigeration energy force checking device.
Background technology
Air conditioning for automobiles is the conventional equipment on automobile, when refrigerating capacity deficiency in air conditioning system, can greatly affect the refrigeration of air-conditioning.If not had cold-producing medium in air conditioning system, driver opens air-conditioning for a long time, is easily caused the compressor lost of life or damage.
At present, driver can only by observe the photoscope on high pressure hard tube differentiate cold-producing medium with or without, the most accurate.If photoscope can be covered by the longer car of the time limit because of dust and impurity, then cannot judge whether vehicle air conditioner also has cold-producing medium.
It would therefore be highly desirable to solution the problems referred to above.
Utility model content
Utility model purpose: the purpose of this utility model be to provide a kind of quickly detect air conditioning for automobiles inner refrigerant pressure, when lack of refrigerant be the automobile air-conditioning refrigeration energy force checking device that can carry out filling.
Technical scheme: the utility model discloses a kind of automobile air-conditioning refrigeration energy force checking device, including casing and the connected pressure detecting joint for detecting the force value of cold-producing medium in air conditioning system, connect on described pressure detecting joint and have pressure transducer and Pressure gauge, it is provided with three way cock between this Pressure gauge and pressure detecting joint, the fluid reservoir for storing cold-producing medium and fluid injection branch road it is provided with in described casing, described fluid injection branch road includes the topping-up pump connected successively with the bottom of fluid reservoir, unidirectional liquid-filling valve and stop valve, this stop valve is connected with pressure detecting joint by three way cock；Described topping-up pump is pulse injection liquid, on this pulse injection liquid connect have the controller for processing refrigerant pressure information, this controller also with stop valve wireless connections.Pressure detecting joint is connected with the high pressure hard tube on automotive air-conditioning system, the force value of cold-producing medium can be obtained on Pressure gauge, if lack of refrigerant in system, the most actually measured force value can be less than standard value, now by fluid injection branch road, air conditioning system can be added cold-producing medium.Force value is transmitted to controller by pressure transducer simultaneously, opens stop valve by controller so that fluid injection branch road is connected, and is pressed in air conditioning system by cold-producing medium by topping-up pump, completes the interpolation of cold-producing medium.
Three way cock two and pressure release branch road it is additionally provided with in described casing, described pressure release branch road includes the second stop valve and the unidirectional relief valve connected with the second stop valve, described stop valve, the second stop valve, three way cock connect with three way cock two respectively, and described unidirectional relief valve connects with fluid reservoir top；Wherein the second stop valve and controller wireless connections.When in pipelines of automobile air conditioner, refrigerant pressure is too high, force value is transmitted to controller by pressure transducer, can open the second stop valve by controller, be reclaimed by cold-producing medium, reduce its pressure, prevent air-conditioning duct from causing crack damage and the compressor lost of life, damage because pressure is excessive.
Wherein, described Pressure gauge is provided with relief valve, this relief valve and controller wireless connections, and the maximum opening of relief valve is less than the maximum opening of the second stop valve.Relief valve aperture is less, the most accurately regulates.
Further, described controller is single-chip microcomputer.
Wherein, controller includes data acquisition unit, data processing unit and display screen.
Beneficial effect: this utility model is compared with prior art, its advantage is: it is the most directly perceived that this automobile air-conditioning refrigeration energy force checking device makes the refrigerant pressure in pipelines of automobile air conditioner show, and cold-producing medium can be added while detection, and air-conditioning duct pressure is accurately regulated, operate more convenient, improve work efficiency and accuracy of detection.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model automobile air-conditioning refrigeration energy force checking device；
Fig. 2 is the schematic diagram of this utility model automobile air-conditioning refrigeration energy force checking device.
Detailed description of the invention
Below in conjunction with the accompanying drawings the technical solution of the utility model is described further.
Such as Fig. 1, shown in Fig. 2, the utility model discloses a kind of automobile air-conditioning refrigeration energy force checking device, including casing 1 and the connected pressure detecting joint 2 for detecting the force value of cold-producing medium in air conditioning system, connect on described pressure detecting joint 2 and have pressure transducer 3 and Pressure gauge 13, it is provided with three way cock 4 between this Pressure gauge 13 and pressure detecting joint 2, the fluid reservoir 5 for storing cold-producing medium and fluid injection branch road it is provided with in described casing 1, described fluid injection branch road includes the topping-up pump 6 that bottom with fluid reservoir 5 connects successively, unidirectional liquid-filling valve 7 and stop valve 8, this stop valve 8 is connected with pressure detecting joint 2 by three way cock 4；Described topping-up pump 6 is pulse injection liquid, on this pulse injection liquid connect have the controller 9 for processing refrigerant pressure information, this controller 9 also with stop valve 8 wireless connections.
Three way cock 2 10 and pressure release branch road it is additionally provided with in casing 1, described pressure release branch road includes the second stop valve 11 and the unidirectional relief valve 12 connected with the second stop valve 11, described stop valve the 8, second stop valve 11, three way cock 4 connect with three way cock 2 10 respectively, and described unidirectional relief valve 12 connects with fluid reservoir 5 top；Wherein the second stop valve 11 and controller 9 wireless connections.
Pressure gauge 13 is provided with relief valve 14, this relief valve 14 and controller 9 wireless connections, and the maximum opening of relief valve 14 is less than the maximum opening of the second stop valve 11.
Controller 9 is single-chip microcomputer, and controller 9 includes data acquisition unit, data processing unit and display screen.
When actually used, pressure detecting joint is connected with the high pressure hard tube on automotive air-conditioning system, the force value of cold-producing medium can be obtained on Pressure gauge, if actually measured force value is less than standard value, lack of refrigerant in surface system, pressure transducer is by force value transmission to controller simultaneously, and controller controls to open stop valve, and controls topping-up pump by fluid injection branch road to adding cold-producing medium in pipeline.Open stop valve so that fluid injection branch road is connected, and opens topping-up pump, being pressed in air conditioning system by cold-producing medium, unidirectional liquid-filling valve is possible to prevent refrigerating fluid to reflux, after Pressure gauge reaches standard value, pressure transducer passes data to controller, closes stop valve, completes the interpolation of cold-producing medium；When in pipelines of automobile air conditioner, refrigerant pressure is too high, data are delivered to controller by pressure transducer, and now controller can open the second stop valve, is reclaimed by cold-producing medium, reduce its pressure, prevent air-conditioning duct from causing crack damage and the compressor lost of life, damage because pressure is excessive；During adding cold-producing medium, if the most overproof value of force value of pipeline after adding cold-producing medium, accurately can be regulated by relief valve.
