Description
Technical field
The present invention relates to valve technology field, is used to control refrigerant break-make particularly in refrigeration plant and flows to electronic
Triple valve.The invention further relates to the refrigeration plant provided with the electric T-shaped valve.
Background technology
The electric T-shaped valve being presently used in the triple valve of refrigeration plant, particularly heat pump type air conditioner pipeline, mostly passes through
The break-make and flow direction of sliding block switching control refrigerant in valve.
Electric T-shaped valve is mainly made up of valve body and coil two parts, and wherein valve body has three valve ports, and its operation principle is
Coil is in the presence of current impulse, and to the electromagnetic force on one direction of magnetic rotor component in valve body, the direction of power can be
Clockwise either counterclockwise, magnetic rotor component is rotated towards the direction of power, pass through a series of gear in valve body
Transmission, power is transferred on sliding block, and sliding block switches in two valve ports wherein under force, plays the work for changing runner
With.
A kind of electric T-shaped valve as disclosed in the application for a patent for invention that application publication number is CN103375606A, its coil are encouraged
The son rotation of magnetic rear-guard turn, power gear 17 are pressed into armature spindle 14a, become one structure, armature spindle is synchronous with power gear 17
Rotation drives reduction gearing 18, performs gear 20.By performing the trundle 25 of gear 20, band movable slider 23 rotates, and makes sliding block
Valve port P1 or P2 are blocked, so as to switch the flow direction of refrigerant (see Fig. 1).
In this technical scheme, respectively on two rooted tooth wheel shafts, centre is slowed down with one for power gear 17 and execution gear 20
