Abstract
The utility model relates to an automobile -used extension valve assembly, which comprises the following components: a valve body, there are valve entry and valve export on the valve body, the valve entry links to each other with receiver drier, valve export and evaporimeter access connection, have on the valve body perforating hole form on the valve body with the first interface of valve entry homonymy to reach the second interface that exports the homonymy with the valve, have the check valve of second interface to the one -way circulation of first interface in the perforating hole. The utility model discloses an extension valve assembly, improve the valve body, make expansion valve and check valve connect in parallel in inside, it changes to be favorable to having formed in the vehicle air conditioner system refrigerant flow direction, realize very easily that car heat pump system reforms transform and car heat pump system designs the application basically, furthermore, the expansion valve valve body has adopted present car to refer to and has used four extensive interface expansion valve valve body interfaces, pipeline overall arrangement to the vehicle air conditioner system can not cause too big influence, the overall arrangement is fit for using in the vehicle air conditioner system.
Description
Technical field
The utility model relates to air-conditioning, tide of motorism pumping system, is specifically related to the automobile-used expansion valve component in air conditioning for automobiles, heat pump.
Background technology
The running of general air-conditioning can be satisfied the demands by common expansion valve, but when relating to tide of motorism pumping system or transformation of the way automotive air-conditioning system, then needs the flow direction changing refrigerant.As shown in Figure 1, when needing the flow direction changing refrigerant, an automotive air-conditioning system expansion valve must be arranged on evaporimeter place, increase the expansion valve that is arranged on condenser inlet again, ensure refrigeration or heat period two expansion valves to only have a participation refrigerant circulation control job, in fact two expansion valve component will be adopted to solve problem, and now expansion valve component is made up of an expansion valve and a check valve.But the mode of conventional external parallel connection has a lot of problem; such as need check valve to be welded on outside expansion valve, cause floor space large, welding procedure is complicated simultaneously; check valve, expansion valve material differ to be welded to connect and cause hydraulic performance decline, and its pipeline often can block.Expansion valve automobile-used mostly at present is H type expansion valve, have four interfaces, two interfaces are identical with common heating power expansion valve, connect liquid storage dryer and be connected evaporator, two other interface, connect evaporator outlet and compressor inlet, four interface expansion valves are widely used in automotive air-conditioning system, connect more for convenience pipeline.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of expansion valve component being convenient to air conditioning for automobiles application, not only can change refrigerant flow direction, and can save space, is convenient to pipeline and connects and layout.
To achieve the above object of the invention, a kind of automobile-used expansion valve component is provided, comprise valve body, described valve body has valve inlet and valve outlet port, described valve inlet is connected with liquid storage dryer, valve outlet port is connected with evaporator, it is characterized in that described valve body has through hole, described through hole forms the first interface with valve inlet homonymy on valve body, and with the second interface of valve outlet port homonymy, have the second interface in through hole to the check valve of first interface one-way flow.
Preferably, the central shaft of described through hole is parallel with the central shaft of valve inlet and valve outlet port.Comprise the part with expansion valve function in described expansion valve component, this part comprises valve inlet, valve outlet port and spool, and described spool can be electric expansion valve, heating power expansion valve or silicon expansion valve.
Expansion valve component of the present utility model, valve body is improved, expansion valve and check valve is made to carry out parallel connection in inside, be conducive in automotive air-conditioning system, define refrigerant flow direction to change, realize the transformation of tide of motorism pumping system and the application of tide of motorism pumping system Basic Design easily, and, expanding valve body have employed present automobile and uses for reference widely used four interface expanding valve body interfaces, pipe-line layout for automotive air-conditioning system can not cause excessive impact, is adapted at application layout in automotive air-conditioning system.
The beneficial effects of the utility model are, in the air conditioning for automobiles transformation of the way, automobile heat pump application, can realize the entrucking application of system architecture principle, transformation of the way application easily; Connected mode is identical with orthodox car air-conditioning connected mode; System and parts take up room little; Realize full aluminium, full copper or the connection of copper aluminium material matter pipeline etc.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Automobile-used expansion valve component according to Fig. 2, comprises valve body 1, and described valve body 1 has valve inlet 2 and valve outlet port 3, valve inlet 2 is parallel with the central shaft of valve outlet port 3, interior connected by spool.Valve body 1 there is through hole, the central shaft of through hole is parallel with the central shaft sending mouth 3 with valve inlet 2, two interfaces are formed in valve body both sides, be respectively and the first interface 4 of valve inlet 2 homonymy and the second interface 5, check valve 6 is had in through hole, check valve 6 is that the second interface 5 is negotiable to first interface 4 direction, the structural design that rightabout then ends.
Automobile-used expansion valve component of the present utility model, valve inlet 2 is connected with liquid storage dryer, and valve outlet port 3 is connected with evaporator.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art can also make all equivalent modification or replacement under the prerequisite without prejudice to the utility model creative spirit, and these equivalent modifications or replacement are all included in the application's claim limited range.
