Description
Technical field
The present invention relates to valve technology fields, for controlling the electronic of refrigerant on-off and flow direction especially in refrigeration equipment
Triple valve.The invention further relates to the refrigeration equipments for being equipped with the electric T-shaped valve.
Background technique
Currently, being used for the triple valve of refrigeration equipment, the especially electric T-shaped valve in heat pump type air conditioner pipeline, mostly pass through
The on-off and flow direction of sliding block switching control refrigerant in valve.
Electric T-shaped valve is mainly made of valve body and coil two parts, and wherein there are three valve ports for valve body, its working principle is that
Under the action of current impulse, to the electromagnetic force on one direction of magnetic rotor component in valve body, the direction of power can be coil
Clockwise either counterclockwise, it rotates magnetic rotor component towards the direction of power, passes 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, coil are encouraged
The 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, executes gear 20.By executing the trundle 25 of gear 20, band movable slider 23 rotates, and makes sliding block
Valve port P1 or P2 are blocked, to switch the flow direction of refrigerant (see Fig. 1).
In this technical solution, respectively on two rooted tooth wheel shafts, centre is slowed down with one for power gear 17 and execution gear 20
The power gear 17 of the connection engaged transmission of gear 18, the lower end armature spindle 14a and indentation is structure as a whole, and power gear 17 subtracts
Fast gear 18 constitutes first order gear pair.Gear drive has higher requirement away from, the depth of parallelism to the center two gears, and
The center of power gear 17 is guaranteed by two casings, upper and lower end cap and valve seat, and 18 center of reduction gearing is then
Guaranteed by valve seat and gear shaft.Thus the center between power gear 17, reduction gearing 18 is on the high side away from association size, is producing
The manufacturing process high expensive of middle correlated parts, the concentricities of two axis it is difficult to ensure that, the transmission after gear assembly is easy to appear
It can not normally engage or stuck phenomenon (see Fig. 2).
Moreover, the frame mode of the single-ended fixation of valve seat of central shaft 24, executes the cooperation of gear 20 and rotates on center shaft
The structure of transmission.The structural dynamic is decelerated after gear 18 is exaggerated tens times, is transferred to and is executed on gear 20, executes gear 20
