Abstract
The utility model provides a throttle valve for heat pump type air conditionings. Two opposed valves of a valve A and a valve B are fixedly arranged in a shell body. The structures of the valve A and the valve B are both that a valve body is arranged, a valve core is arranged in the valve body, the middle part of the valve core is provided with a jet hole, and one end opposite an inlet and an outlet on the valve body is connected with a filter net. The utility model can replace a capillary and a one-way valve and can be used for conveniently carrying out the flow direction conversion of cold medium during refrigeration and heat manufacture. The utility model has simple structure, convenient installation and low cost.
Description
The utility model relates to a kind of adjusting and dodges, particularly the modulating valve of refrigerant body flow, the flow direction in the splitting heat pump air conditioner device.
Refrigerant body flow generally adopts capillary tube to regulate in the splitting heat pump air conditioner device at present, bigger as need refrigerant body flow, then, less as need refrigerant body flow with short capillary tube, then adopt long capillary tube, this just need install some capillaries in air-conditioner hose, in addition, be realization refrigeration, refrigerant direction of flow conversion when heating, capillary tube also must be connected with one-way valve, this modulating valve complex structure of being made up of some capillaries, one-way valve, cost is high and install difficult.
The purpose of this utility model is to design a kind of bidirectional throttling valve that replaces capillary tube, one-way valve, and can freeze, refrigerant direction of flow conversion when heating.
The technical solution of the utility model is as follows: the housing internal fixation has two relative valves (A) and valve (B), valve (A) comprises that an end is fixed with the valve body of pad (8) (2), valve body (2) middle part has through hole (7), its large aperture part has a spool (3), spool (3) middle part has spray orifice (4), go up an end of importing and exporting (5) relatively at valve body (2) and be connected with filter screen (6), valve (B) comprises that an end is fixed with the valve body of pad (88) (22), valve body (22) middle part has through hole (77), its large aperture part has a spool (33), spool (33) middle part has spray orifice (44), goes up an end of importing and exporting (55) relatively at valve body (22) and is connected with filter screen (66).
The utility model adopts two relative valve A and valve B, structure is: a valve body, a spool is arranged in the valve body, the spool middle part has spray orifice, and an end of importing and exporting relatively on valve body is connected with filter screen, and the utility model can replace capillary tube, one-way valve, and can conveniently freeze, refrigerant direction of flow conversion when heating, simple in structure, easy for installation, cost is low.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with description of drawings embodiment:
Throttle valve is installed in the air-conditioner hose, when air conditioner heat-production, the filter screen 6 that the refrigerant body passes through valve A from the import and export 5 of housing 1 enters the through hole 7 in the middle of the valve body 2, spool 3 is dashed to be blocked to the other end of through hole 7 and by pad 8, the refrigerant body enters valve B from the gap and spray orifice 4 outflows of spool 3 accessibke porosities 7, dash spool 33 to the small aperture part of through hole 77 and be blocked, this moment, the refrigerant body can only flow out from importing and exporting 55 through filter screen 66 from 44 ejections of the spray orifice the spool 33.
If air conditioner need freeze, then the refrigerant direction of flow is opposite, enters valve B from importing and exporting 55, flows out from importing and exporting 5 through valve A again.
