Description
Technical field
The utility model belongs to automotive air-conditioning system technical field, is related to a kind of automotive air-conditioning system coolant charging device.
Background technology
Air-conditioning system connecting line is in the layout of vehicle, in the status of a comparative disadvantage, i.e. air-conditioner pipe
The arrangement on road need avoid vehicle on other parts, and the position of air-conditioning duct charging valve sometimes by vehicle and other zero
The limitation of component, location can be extremely difficult when refrigerant R134a is filled, and very big puzzlement is caused to operating personnel.
Utility model content
The purpose of this utility model is to provide a kind of automotive air-conditioning system coolant charging device, solves and deposits in the prior art
Air conditioning for automobiles refrigerant R134a fill difficult problem.
The utility model fills the technical scheme adopted is that a kind of automotive air-conditioning system coolant charging device including low pressure
Valve branch pipe and high pressure charging valve branch pipe are noted, low pressure charging valve branch pipe welding is on evaporator and compressor connecting tube, high pressure filling
For valve branch pipe welding on condenser and evaporator joint pipe, the end of low pressure charging valve branch pipe is connected with low pressure charging valve, high pressure
Charging valve branch pipe end is connected with high pressure charging valve.
The utility model is further characterized in that,
Compression pneumatic valve core is both provided in low pressure charging valve and high pressure charging valve.
Evaporator offers connecting hole with the junction with low pressure charging valve branch pipe in compressor connecting tube.
Condenser offers connecting hole with the junction with high pressure charging valve branch pipe on evaporator joint pipe.
Low pressure charging valve branch pipe and high pressure charging valve branch pipe are adjustable hard tube.
The position of low pressure charging valve branch pipe and high pressure charging valve branch pipe is adjacent.
The beneficial effects of the utility model are the low pressure charging valve branch pipe for being welded with low pressure charging valve and to be welded with high pressure filling
The high pressure charging valve branch pipe of valve is respectively welded on evaporator and compressor connecting tube and condenser and evaporator joint pipe, profit
With low pressure charging valve branch pipe and high pressure charging valve branch pipe, being directly welded at evaporator and the low pressure in compressor connecting tube originally
Charging valve and the high pressure charging valve being directly welded on condenser and evaporator joint pipe, are directed to one and facilitate refrigerant R134a
The spatial position of filling so as to solve the problems, such as that operating personnel's filling refrigerant R134a is difficult, facilitates refrigerant R134a
The operation of filling personnel saves working hour and reduces work difficulty.
