Abstract
The utility model relates to a kind of novel seal new-energy automotive air-conditioning pipes.The joint portion of air-conditioner pipe (1) is provided with sealing structure (2)；The sealing structure (2) includes several annular grooves (21) for being provided with the air-conditioner pipe (1) outer surface, it is provided with the gasket (22) being fastened in the annular groove (21) being wholely set in the annular groove (21), is provided with sealing ring (23) and is fastened on the clamping formed on the outside of the gasket (22) to the gasket (22).The utility model passes through the double set of gasket and sealing ring, first makes gasket and tubule form good close contact, second sealing ring and big pipe form good close contact, the mutual expanding force that gasket and sealing ring generate compresses gasket closely, so that sealing ring is obtained a degree of expansion, guarantees to manage and be set on greatly tubule sealing performance between the two in big manage.
Description
Technical field
The utility model relates to a kind of novel seal new-energy automotive air-conditioning pipes, belong to pipe fitting preparation technical field.
Background technique
Air-conditioning duct is numerous, in the connection procedure of adjacent pipe sections, how can guarantee its sealing performance just at a weight
The problem of wanting, most of existing market is all that a seal groove carries out link sealing, and sealing ring seals after prolonged use
Performance decline is easy to produce refrigerant leakage, influences air conditioner refrigeration effect, it is therefore desirable to be improved.
Utility model content
The utility model improves air-conditioner pipe sealing performance in view of the foregoing drawbacks, and it is an object of the present invention to provide a kind of structurally reasonable
A kind of novel seal new-energy automotive air-conditioning pipe.
The technical solution adopted in the utility model is thus: a kind of novel seal new-energy automotive air-conditioning pipe, in air-conditioner pipe
(1) joint portion is provided with sealing structure (2)；
The sealing structure (2) includes several annular grooves (21) for being provided with the air-conditioner pipe (1) outer surface, described
Annular groove (21) is provided with the gasket (22) being fastened in the annular groove (21) being wholely set, and is provided with sealing ring
(23) it is fastened on the clamping formed on the outside of the gasket (22) to the gasket (22).
It is provided with nut (3) outside air-conditioner pipe (1), the nut forms the compression to the sealing structure (2) when screwing in.
The gasket (22) is recessed card slot, and sealing ring (23) card is set into the gasket (22).
The sealing ring (23) is made of elastic material, and the sealing ring (23) is provided with cavity, can in the cavity
It is logical to be equipped with high pressure gas.
The utility model has the advantages that: the utility model passes through the double set of gasket and sealing ring, and first makes to seal
Pad and tubule form good close contact, and the second sealing ring and big pipe form good close contact, gasket and sealing ring
The mutual expanding force generated compresses gasket closely, and sealing ring is made to obtain a degree of expansion, guarantee big pipe and
It is set on tubule sealing performance between the two in big manage.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
1 it is air-conditioner pipe in figure, 2 be sealing structure, 3 is nut；
21 it is annular groove, 22 be gasket, 23 is sealing ring.
Specific embodiment
A kind of novel seal new-energy automotive air-conditioning pipe is provided with sealing structure 2 at the joint portion of air-conditioner pipe 1；
The sealing structure 2 includes several annular grooves 21 for being provided with 1 outer surface of air-conditioner pipe, recessed in the annular
Slot 21 is provided with the gasket 22 being fastened in the annular groove 21 being wholely set, be provided with sealing ring 23 be fastened on it is described
The clamping to the gasket 22 is formed on the outside of gasket 22.
Nut 3 is provided with outside air-conditioner pipe 1, the nut forms the compression to the sealing structure 2 when screwing in.
The gasket 22 is recessed card slot, and the card of sealing ring 23 is set into the gasket 22.
The sealing ring 23 is made of elastic material, and the sealing ring 23 is provided with cavity, sets in the cavity Nei Ketong
There is high pressure gas
Further explanation is made to the utility model below, to be better understood by the utility model: the utility model is first
Gasket 22 is fastened in annular groove 21, the profile of gasket 22 and annular groove is corresponding, guarantees that gasket 22 can be close
Support be located in the annular groove 21, after gasket 22 is installed, then by sealing ring 23 loading be fastened on the sealing
The surface of pad 22 forms the compression to the gasket 22, and the conflict for keeping gasket 22 even closer is in the annular groove
Within 21；The reaction force that opposite gasket 22 forms sealing ring 23 makes sealing ring 23 generate certain expansion, so that institute
Inner surface in big pipe can closely be contradicted by stating sealing ring 23, to improve the sealing performance between big pipe and tubule；This reality simultaneously
Novel sealing ring 23 is provided with cavity, when the elasticity of sealing ring 23 is by certain reduce, by being passed through gas in cavity
This influence that 23 elasticity of compensation sealing ring reduces, it is ensured that connection reliability and sealing performance between big pipe and tubule.
