Specific embodiment
The core of the present invention is to provide a kind of sealing ring, to improve its position stability, thus improving sealing effectiveness.This
Another bright core is to provide a kind of vaporizer with above-mentioned sealing ring.Also one core of the present invention is to provide a kind of tool
There is the air-conditioner of above-mentioned vaporizer.
In order that those skilled in the art more fully understand the present invention program, below in conjunction with the accompanying drawings with embodiment to this
Invention is described in further detail.
Refer to shown in Fig. 5-Fig. 8, the embodiment of the invention discloses a kind of sealing ring 1 of vaporizer, be used for being arranged on steaming
Send out between device pipe joint 3 and self-styled nut 4, and positioned by compacting ring 2, wherein, this sealing ring 1 is had for being blocked with compacting ring 2
Connect the buckling groove 11 of laminating.The application increases its contact between compacting ring 2 by opening up buckling groove 11 on sealing ring 1
Area, reduces the deformation that sealing ring 1 produces because of the extruding of compacting ring 2 simultaneously, and this makes sealing ring 1 and compacting ring 2 coordinate tightly
Close, positioning is reliable, is difficult to separate with compacting ring 2 after sealing ring 1 stress or deformation, thus improve the steady of sealing ring 1 positioning
Qualitative, and then improve vaporizer sealing.
Further, since offering buckling groove 11 on sealing ring 1, it therefore reduces because compacting ring 2 extrudes to sealing ring 1
And the deformation producing, in self-styled nut 4 with evaporator tube joint 3 seal process, self-styled nut 4 bottom inclined plane pair can be avoided
The shearing of sealing ring 1, thus avoiding leakage, improves the service life of sealing ring 1 simultaneously.
In specific embodiment, buckling groove 11 is opened in the side away from sealing ring 1 center for the sealing ring 1, that is, is opened in
The outside of sealing ring 1.It will be appreciated by persons skilled in the art that in practice, can be according to the phase of sealing ring 1 and compacting ring 2
Para-position installs the particular location determining buckling groove 11, merely provides a kind of mode of setting, but the application is not only in the present embodiment
It is limited to this position.
In order to be further ensured that the stability being connected between sealing ring 1 and compacting ring 2, by sealing ring 1 in the present embodiment
Buckling groove 11 be set to the cannelure circumferentially along sealing ring 1.Sealing ring 1 can be made to pass through buckling groove 11 by above-mentioned setting
Fit completely with compacting ring 2, greatly increase the contact area of sealing ring 1 and compacting ring 2, thus it is fixed to improve sealing ring 1
The reliability of position.In practical operation, also buckling groove 11 can be set to multiple sulculuses circumferentially along sealing ring 1, and lead to
Crossing multiple sulculuses makes sealing ring 1 be connected with compacting ring 2, and the mode that specifically opens up will have the face that compacting ring 1 contacted with sealing ring 2
Shape is configured.
On the basis of technique scheme, in the present embodiment, the shape of cross section of buckling groove 11 is set to L-type, L-type
Buckling groove 11 contact with compacting ring 2 with two faces can be provided, increase the contact area of sealing ring 1 and compacting ring 2.In reality
In also buckling groove 11 can be set to U-type groove, due to compacting ring 2 have certain thickness and need fit with evaporator tube joint 3,
Therefore, for the ease of compacting ring 2 is fitted with buckling groove 11 it is preferable that buckling groove 11 is set to L-type groove, but other shapes
Buckling groove 11 also in protection domain.
In preferred embodiment, the cross section of sealing ring 1 is set to the sector that central angle is 270 °, i.e. this sealing ring
1 is 3/4ths rounded face.During installation, sealing ring 1 is arranged on evaporator tube joint 3, then by compacting ring 2, it is entered
Row location and installation, specifically, a drift angle of compacting ring 2 is fitted with buckling groove 11, and that is, sealing ring 1 and compacting ring 2 pass through two
The laminating of individual face, limits the degree of freedom of sealing ring 1 both direction, in combination with evaporator tube joint 3 it is achieved that to sealing ring 1
Location and installation.In practice, sealing ring 1 of different shapes can be arranged according to different requirements, as long as have can be with compression
The buckling groove 11 of circle 2 laminating.Additionally, the size for buckling groove 11 can be according to the relative size of compacting ring 2 and sealing ring 1
Selected, and all in protection domain.
Present invention also offers a kind of vaporizer, it includes evaporator tube joint 3, self-styled nut 4 and with compacting ring 2
For sealing the sealing ring 1 of vaporizer joint 3 and self-styled nut 4, wherein, the sealing that this sealing ring 1 provides for above-described embodiment
Circle 1.Because the sealing ring 1 that this sealing ring 1 such as above-described embodiment provides is identical, therefore, the vaporizer with this sealing ring 1 also has
There is above-mentioned technique effect.
Specifically, by the buckling groove 11 of sealing ring 1, fit in the base angle of the side away from evaporator tube joint 3 with compacting ring 2
（Specify, when the base angle of compacting ring 1 is normally placed for vaporizer, near the side of vaporizer valve element herein）, i.e. the opening of sealing ring 1
Mouth direction is away from the direction of self-styled nut 4.By above-mentioned setting, can make sealing ring 1 simultaneously with evaporator tube joint 3 and self-styled spiral shell
Female 4 contacts, realize both sealings, and realize positioning by compacting ring 2.
The compacting ring 2 providing in the present embodiment is stereosphere, when installing self-styled nut 4, self-styled nut 4 crush seal circle
1 makes it to the side deformation away from compacting ring 2, and due to compacting ring 2 and buckling groove 11 cooperation positioning, reduces sealing ring 1 fixed
Position deformation, this makes sealing ring 1 little to the deflection of the deflection less buckling groove 11 away from compacting ring 2 side, therefore, can
Effectively reduce the shearing to sealing ring 1 for the self-styled nut 4, it is to avoid reveal, improve service life.
Present invention also offers a kind of air-conditioner, including vaporizer, and this vaporizer is the vaporizer of above-mentioned offer, due to
Vaporizer has above-mentioned technique effect, and therefore, the air-conditioner with this vaporizer also has above-mentioned technique effect.
In this specification, each embodiment is described by the way of going forward one by one, and what each embodiment stressed is and other
The difference of embodiment, between each embodiment identical similar portion mutually referring to.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.
Multiple modifications to these embodiments will be apparent from for those skilled in the art, as defined herein
General Principle can be realized without departing from the spirit or scope of the present invention in other embodiments.Therefore, the present invention
It is not intended to be limited to the embodiments shown herein, and be to fit to and principles disclosed herein and features of novelty phase one
The scope the widest causing.
