Abstract
The utility model discloses a kind of manually opened tool for electric expansion valve, the manually opened tool is the circular ring shape magnet for cooperating electronic expansion valve body.The utility model can be manually rotated the opening and closing of control electronic expansion valve body by circular ring shape magnet, what be can be convenient detects electric expansion valve fault point, illustrate that the coil of electric expansion valve is out of order if can be opened and closed manually, is otherwise exactly that electronic expansion valve body breaks down.
Description
Technical field
The utility model relates to a kind of electric expansion valve tool, in particular to a kind of for the manually opened of electric expansion valve
Tool.
Background technique
For convertible frequency air-conditioner, it relies primarily on electric expansion valve and accurately controls cold medium flux, existing electric expansion valve at present
Its main operational principle is stator coil socket valve body, passes through the intracorporal magnet rotor rotation control of stator coil control valve
The aperture of spool reaches cold medium flux control.Its structure of the magnet of magnet rotor is such as China Patent No. at present
The magnetic rotor structure of the solenoid valve of CN02254673.1 is identical, this electric expansion valve itself once break down often can not
Where judge fault point, for example be coil problem or valve body problem, this electric expansion valve of another aspect is can not be manual
Opening and closing, how to solve above-mentioned technical problem is the object that those skilled in the art need to study.
Summary of the invention
The utility model provides the manually opened work that a kind of structure is simple, breakdown judge is readily used for electric expansion valve
Tool.
A kind of manually opened tool for electric expansion valve, the manually opened tool are cooperation electric expansion valve valve
The circular ring shape magnet of body can be manually rotated the opening and closing of control electronic expansion valve body by circular ring shape magnet.The electronic expansion
It is equipped with stop assembly and magnet rotor in valve body, stop assembly includes the silk braid nut of integrated injection molding, outside silk braid nut
It is equipped with guide thread week, guide thread periphery is combined with locating snap ring, and locating snap ring cooperation contact is set to the guiding on the inside of magnet rotor
Muscle.The silk braid nut guide thread bottom is equipped with lower backstop muscle, and baffle ring is housed at the top of guide thread, controls the upper of needle
Down stroke.This kind of electromagnetic valve body uses the guiding rib structure of magnet rotor, can be manually rotated lower control stop in circular ring shape magnet
Ring is rotated along guide thread, and the stroke up and down for controlling needle reaches the manual opening and closing function of electric expansion valve.
The circular ring shape magnet is radially provided with evenly distributed magnetic stripe, the magnetism of the magnetic cooperation magnet rotor of magnetic stripe.
The magnet rotor magnet is column circular ring structure, is equipped on the inside of column annulus along axial raised guiding rib,
Insertion is connected with guiding steel disc at the top of column annulus one end, and guiding steel disc center is equipped with the bending of protrusion, and bending is equipped with guiding
Circular hole；Thickening at the top of wall ring and guiding rib on the guiding steel disc downside contact column annulus.Magnet rotor magnet
Cooperate guiding two guide frames of steel disc to realize that the guide function of magnet rotor is accepted by guiding rib, simplifies magnetic turn indirectly
The structure of son, realizes the dual guidance capability of magnet rotor magnet.
The utility model can be manually rotated the opening and closing of control electronic expansion valve body by circular ring shape magnet, it may be convenient to examine
Electric expansion valve fault point is measured, illustrates that the coil of electric expansion valve is out of order if can be opened and closed manually, is otherwise exactly electronics
Expanding valve body breaks down.

The cooperation contact of locating snap ring 10 is set to the guiding rib 1 on the inside of magnet rotor, in the process that the controlled circular ring shape magnet 7 of magnet rotor rotates
The needle of middle control 10 up and down motion of locating snap ring i.e. magnet rotor connection moves up and down, and reaches the technology mesh being opened and closed manually
's.13 guide thread bottom of silk braid nut is equipped with lower backstop muscle 12, and baffle ring 8 is housed at the top of guide thread, controls the upper of needle
Down stroke.Magnet rotor magnet 5 is column circular ring structure, is equipped on the inside of column annulus along axial raised guiding rib 1, column circle
Insertion is connected with guiding steel disc 2 at the top of ring one end, and guiding 2 center of steel disc is equipped with the bending 4 of protrusion, and bending 4 is equipped with guiding circle
Hole 6 reaches the technical purpose of dual guiding.
Thickening on 2 downside of steel disc contact column annulus is preferably directed as structure to increase at the top of wall ring 3 and guiding rib 1
Add magnet rotor magnet for the support performance of guiding steel disc 2.
Being preferably directed muscle cross section as structure is that triangle is trapezoidal or arc-shaped.
