Description
Technical field
This utility model belongs to valve mechanism technical field, especially relevant with coil with a kind of valve.
Background technology
Electric expansion valve is the part of conventional regulation refrigerant fluid flow in the refrigerating plants such as air-conditioning, refrigerator.Electronics
Expansion valve includes body portion and coiler part, and body portion includes expanding sleeve, valve body, valve seat, valve rod and needle, and stretching is sheathed
There is central through hole, expanding sleeve is coated at the upper end of valve body by central through hole, coiler part includes coil, dynamic iron core and quiet ferrum
Core, coil is installed by coil holder, is provided with and houses intracavity for the coil that coil houses, coil holder is provided with coil holder
Central through hole fixed jacket is in expanding sleeve, when traditional coil holder is set with expanding sleeve, easily makes coil holder and expanding sleeve
Between connect tight, easily cause expanding sleeve rotation and come off；Secondly, the internal chamber wall of coil containing cavity and position are stretched between set outer wall
Easily accumulate acidic fluid, acidic fluid easily causes the corrosion of expanding sleeve.
Utility model content
The purpose of this utility model be intended to overcome be connected between the coil holder of existing electric expansion valve and expanding sleeve not tight
Lead to the expanding sleeve defect with corrosion easy to fall off, provide one kind to be completely embedded, the expanding sleeve electronic expansion with corrosion difficult for drop-off
Valve.
For this reason, this utility model employs the following technical solutions：A kind of valve coil, including coil and coil holder, coil holder
Middle part setting installation through-hole, coil holder is coated at expanding sleeve by installation through-hole, is provided with along installation through-hole circumference side in coil holder
To coil containing cavity, coil is set around in coil containing cavity, it is characterized in that, on the inner wall of end of described coil holder installation through-hole
It is provided with sealing structure, make to be completely embedded between coil holder and described expanding sleeve by sealing structure, and good airproof performance.
As to the supplement of technique scheme and perfect, this utility model also includes following technical characteristic.
Described sealing structure includes two O-ring seals, on the two ends aperture inwall of the installation through-hole of described coil holder all
It is provided with the annular groove installing O-ring seals for cooperation, two annulars that two O-ring seals are flush-mounted in coil holder respectively are recessed
In groove, when coil holder is set in expanding sleeve, the inwall of O-ring seals, closely against in the outer wall of described expanding sleeve, makes stretching
It is completely embedded between set and coil holder, and good airproof performance.
Described sealing structure includes O-ring seals, and an end cap of described coil holder installation through-hole, equipped with a capping, makes
Installation through-hole forms one end closing, the expanding sleeve installation cavity of one end open, and the accent wall of expanding sleeve installation cavity is provided with for joining
Close the annular groove installing O-ring seals, O-ring seals are flush-mounted in annular groove, when expanding sleeve is installed on drawing of coil holder
When stretching set installation cavity, the inwall of O-ring seals, closely against in expanding sleeve outer wall, makes to be completely embedded between expanding sleeve and coil holder
And good airproof performance.
Described capping is connected as a single entity with the fixation of described coil holder, and capping is shaped by integrated through injection molding.
This utility model can reach following beneficial effect：1st, pass through to arrange on the inner wall of end of coil holder installation through-hole
Sealing ring, when coil holder is set in expanding sleeve, makes to be completely embedded between expanding sleeve and coil holder, and good airproof performance, acid stream
Body will not enter coil containing cavity cavity wall and position is stretched between set outer wall, it is to avoid the corrosion to expanding sleeve；2nd, also can be by online
One end of ring support installation through-hole arranges integrally formed capping, and other end setting sealing ring is carried out between expanding sleeve and coil holder
Sealing, realizes being completely embedded between expanding sleeve and coil holder, and the purpose of good airproof performance, it also avoid because accumulating acid stream simultaneously
Body and cause the problem of expanding sleeve corrosion.
