Description
Technical field
The present invention relates to motor-driven valve technical field, specially a kind of motor-driven valve chocking construction and motor-driven valve.
Background technique
Motor-driven valve is mainly used in refrigeration equipment, is frequency changing refrigeration system core element, cooperates frequency-changeable compressor, passes through
Change the circulation area of valve port to adjust the flow for flowing through motor-driven valve, so that refrigeration equipment is in optimal operating condition always.One
As motor-driven valve be to be driven by stepper motor, but need to increase stop mechanism inside motor-driven valve, guarantee the operation of motor-driven valve valve opening
It encloses number and valve closing operation circle number is constant, facilitate control of the microcomputer to motor-driven valve, reduce motor-driven valve and adjust the influence to system repeatedly.
Therefore stop mechanism is important one of the mechanism of motor-driven valve.It is mutually hit since two kinds of parts can occur when motor-driven valve stop,
Improving stop mechanism anti-collision performance and reducing impact noise is motor-driven valve important subject.
If Chinese patent discloses " a kind of stopper structure ", Patent No.: CN101629649A, the patent are intended to avoid
Retainer uses metal parts, and reduce stop strike note makes armature spindle and magnet rotor to the dress of support member in the motor-driven valve
It is easy to carry out with operation.Armature spindle and magnet rotor are constituted with different components.Fixed upper end bridle is formed in support member, is being propped up
