Abstract
Description
The present invention is a leak detection device including a pneumatic motor and a plurality of suction pipes and discharge pipes connected thereto, and a leak detector and an air conditioner gas using the same, which makes it easy to grasp a gas leak of a compressor, a condenser, an evaporator, and an expansion valve forming a closed circuit. A leak detection system.
In general, automotive air conditioners are largely composed of a compressor for compressing air conditioner refrigerant, a condenser for liquefying a high-pressure refrigerant, an evaporator for vaporizing the liquefied refrigerant, and a blower for blowing cooled air into the room and connected to the connection pipe.
Therefore, the air conditioner of the car is filled with refrigerant gas inside the parts, and after running for a certain period of time, the parts themselves are old and the refrigerant gas filled inside leaks, so that the cold wind does not occur properly. Find a car repair shop.
At this time, the auto repair shop first collects the refrigerant gas remaining in the inside of the car's piping in order to leak the air conditioner, compresses it in a vacuum state, checks the value by gauge gauge, and applies soapy water to the pipe connection part. Look for soap bubbles and check for leaks.
However, the above-described method is a primary initial method, and if it leaks minutely, it cannot be easily found, so each component of the air conditioner is disassembled and inspected in the vehicle body.
The disassembled parts are compressed by the compressor connecting air to the connector formed on both sides so that the air compressed by the refrigerant can be circulated by the blower, and checks the scale of the gauge and checks the abnormality.
However, the air conditioner as the air conditioner is formed with a connector to circulate the air cooled in the compressor, condenser, evaporator, and blower. Since the diameter size of the connector is different from each other, each nozzle packing according to the size of the component is checked. Has the trouble of having to have a problem that reduces the work efficiency.
In order to improve such a problem, the registered utility model No. 354305 discloses a nozzle packing for air conditioner gas leak inspection, the configuration of which is connected to the
At this time, the nozzle jaw (2) is a cylindrical shape spiral tube (3) and the fitting tube (4) is integrally through so that the inside tapered toward the smaller fitting tube (4) to maximize the suction and discharge pressure It is installed, the
The nozzle packing as described above, the nozzle packing (1) connecting the connection hose for generating a vacuum to the connecting portion (7) formed in the radiator (6) of each of the parts of the air conditioner, respectively disassembled each part Insert both ends of the
However, in the method of confirming the vacuum using the nozzle packing as described above, after disassembling in the vehicle body of each component constituting the air conditioner, the operation is cumbersome and the operation is cumbersome, and the vacuum of each component is confirmed. It should be increased the working time, there is an inconvenience that there must be a separate operator to close the nozzle packing (1) to the parts.
An object of the present invention for improving the conventional problems as described above, it is possible to easily grasp the leaking portion of the gas without disassembling the entire air conditioning system, and to easily identify the leaking portion of each unit component, Leak detector to prevent the increase of work load due to disassembly and coupling of the system, and when a negative pressure occurs, a plurality of nozzle tips are in close contact with each component to enable the detection of a gas leak by a single worker and using the same To provide air conditioning gas leak detection system.
The present invention provides a leak detector comprising a pneumatic motor and a plurality of suction pipes and discharge pipes connected thereto, and the pressure gauge is provided on the pipe passage to which the pneumatic motor is connected.
In addition, the suction pipe of the present invention is connected to the exhaust line is connected to the pressure gauge and the pneumatic motor, the suction pipe provides a leak detector consisting of a configuration that is installed to have a diameter difference.
In addition, the suction pipe of the present invention, the nozzle tip is further connected, the nozzle tip has a tapered surface and the nozzle tip is formed in the thread and the guide block which is positioned in the compressor while the nozzle tip is supported in the vertical direction to support the vertical direction To provide a leak detector.
On the other hand, the present invention, when the compressor, the condenser, the evaporator, and the expansion valve constituting the automotive air conditioner are connected to the connecting pipe to form a closed circuit, respectively, three-way valves are respectively installed at the front and rear ends of the compressor, the condenser, the evaporator, and the expansion valve. An air conditioner using a leak detector composed of a compressor, a condenser, an evaporator, and an expansion valve connected to a suction pipe of a leak detection device, respectively, to detect a gas leak by generating negative air pressure. Provide a gas leak detection system.
In addition, the closed circuit of the present invention, the air conditioner using the leak detector made of a configuration to detect the leakage of the closed circuit when generating the negative air pressure as a leak detector by opening only two three-way valve selected from the plurality of three-way valve. Provide a gas leak detection system.
As described above, according to the present invention, it is possible to easily grasp the leaked part of the gas without disassembling the entire air conditioner system, and to easily identify the leaked part of each unit part, and to increase the workload due to the disassembly and coupling of the whole system. When the negative pressure is generated, a plurality of nozzle tips are in close contact with each component, so that one person can detect a gas leak.
