Abstract
The utility model provides a four-way change valve of a heat pump air conditioner. The four-way change valve of a heat pump air conditioner is characterized in that the corresponding surfaces of cylinders which are matched with four inlets and outlets of refrigerant are respectively provided with one axial groove, and a valve core which passes through the oblique through hole of a shaft core and shares the same axial line with the axial groove is arranged. The valve core is directly controlled by an electromagnet coil. The quadratic valve control of the existing four-way change valve is simplified. The four-way change valve of a heat pump air conditioner has very simple structure and flexible control.
Description
The utility model relates to a kind of change-over valve of air conditioner, particularly heat pump air conditioner cooling and heating conversion equipment.The effect of four-way change-over valve is exactly that the suction tracheae of refrigeration system is exchanged, make original when refrigeration become condenser when heating as vaporizer, and original condenser is made vaporizer.Such refrigeration system as a result is to outdoor heat absorption, and to indoor heat extraction.But existing four-way change-over valve is the secondary combination brake switch and proporting, and poor reliability usually makes heat pump air conditioner not heat.
The purpose of this utility model is the device that a kind of better reliability will be provided, and it can realize conversion reliably.
The purpose of this utility model is achieved in that cooperating the spool of conversion with four import and export is Cylinder, and respectively there is an axial groove on the corresponding surface of Cylinder, with each groove coaxial line the oblique through hole that passes the axle center is arranged.Groove, four import and export in hole and refrigeration agent cooperate.When electromagnet coil power, tooth bar armature is spurred tooth bar by electromagnetic fields attract, driving gear, gear and poppet shaft are to fixing, gear is by tooth bar transmission rotation half cycle, and spool promptly changes half cycle, and the former seated position of the slotted eye of spool is just in time exchanged with groove, the hole on corresponding surface, refrigerant cycle promptly changes the flow direction, to indoor heat extraction.Disconnect the electric current of electromagnet coil, spring promotes the tooth bar armature driving gear half cycle that circles round, the spool half cycle that promptly circles round, and spool groove, hole home position are promptly to indoor cooling.
The utility model is simpler than existing secondary combination brake switch and proporting, but reliable.
The concrete structure of model utility is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is heat pump air conditioner refrigeration cycle schematic representation (comprises valve body structure figure spool groove, hole put original position and promptly cooperate with four import and export of refrigeration cycle)
Fig. 2 is that heat pump air conditioner heats circulation schematic representation (comprise valve body structure figure, spool groove, hole original position are exchanged promptly and heated four import and export of circulation and cooperate)
Spool schematic representation in Fig. 3 four-way change valve.
The utility model proposes the details and the working condition of concrete device below in conjunction with Fig. 1-3 detail explanation foundation:
This device comprises that valve body (a 1) garden post symmetrical surface that four import and export are arranged respectively has the oblique through hole that passes the axle center of an axial groove and groove coaxial line, and groove, hole are imported and exported the hold concurrently tooth bar armature (3) of armature purposes of the spool (2) that cooperates and gear (4) driving gear (4) of spool (2) axial restraint with (1) four of valve body respectively and utilized the electromagnet coil (6) of magnetic field suction tooth bar armature (3) to promote spring (5) composition that tooth bar armature (3) driving gear (4) resets spool (2).
Fig. 1 electromagnet coil (6) no electric circuit, four import and export of spool (2) and refrigeration cycle cooperate, i.e. refrigeration.
Fig. 2 electromagnet coil (6) energising, electromagnetic fields attract and spur tooth bar armature (3) driving gear (4) rotation half cycle, spool (2) promptly rotates half cycle, and spool (2) groove, hole are just in time exchanged with corresponding surface groove, hole, refrigeration agent promptly changes flow direction circulation, and heat this moment.Tripping magnet coil (6) electric current is the reposition refrigeration.
Claims (1)
1, four-way change-over valve is by the valve body that four import and export of refrigeration agent are arranged (1), respectively there is an axial groove on the corresponding surface of Cylinder, with the groove coaxial line spool (2) that passes the oblique through hole in axle center is arranged, tooth bar armature (3), gear (4), spring (5), the overall structure that electromagnet coil (6) is formed, it is characterized in that: spool (2) Cylinder symmetrical surface respectively has an axial groove, passes four import and export of oblique through hole in axle center and refrigeration agent with the groove coaxial line and cooperates.
