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
Fixed upper end bridle is formed on the part of support part.Movable upper end bridle is formed on armature spindle.Support member is formed with resin, is turned
Sub- axis and magnet rotor.The external screw thread of armature spindle is screwed into the internal screw thread of support member, on the supporting member by armature spindle installation.
In the position that movable upper end bridle and fixed upper end bridle are not interfered, magnet rotor is entrenched in the holding section of armature spindle and tight
Gu.Magnet rotor is made into the structure that the side opposite with needle portion can be chimeric with the holding section of armature spindle.Limit is provided on rotor simultaneously
Dynamic portion carries out limes superiors limit to rotor, since lower retainer bridle part comparison is small, generally by integrated with armature spindle
Injection molding is formed, and material is identical as rotor shaft material, and armature spindle requires wearability and coefficient of friction low, is required not impact
Height, and bridle needs strike note low and the material of impact resistance, the two is difficult to be compatible with.Bridle is integrally infused with rotor simultaneously
It is moulded into type, two bridle sets up separately on two parts, is unfavorable for size Control, and stopping accuracy has a certain impact.Restraint
Device and rotor integrated injection molding, material is magnetic material, and impact resistance is lower.Armature spindle and rotor assembly position simultaneously
Length is short, also its very unfavorable positioning accuracy.
Summary of the invention
The purpose of the present invention is to provide a kind of motor-driven valve chocking construction and motor-driven valve, have good excellent of using effect
Point solves the problems, such as that traditional retainer assembly is inconvenient, production is not easy, stop noise is big, the impact resistance service life is short.
