Abstract
An air-conditioner double-seal joint comprises a copper joint component and a stop valve component. The sealing conical faces of the copper joint component and the stop valve component are connected through a horn mouth of a connecting pipe and are sealed through copper nuts in screwed up mode. The air-conditioner double-seal joint is characterized in that sealing grooves are respectively arranged on the copper joint component and the stop valve component. Sealing rings are arranged in the sealing grooves. The sealing rings contact with the inner walls of the opening portions of the copper nuts. Sealing embedded grooves are respectively arranged in the inner walls of the end portions of the two copper nuts. O-shaped rings are arranged in the sealing embedded grooves and respectively contact with the outer walls of the copper joint component and the stop valve component. Due to two sealing of the sealing rings and the O-shaped rings, even if the sealing of the conical faces loses effectiveness, a refrigerant of the air conditioner can not be leaked, and refrigeration or heating effect of the air conditioner can be kept in a good condition.
Description
Technical field
The utility model relates to a kind of air conditioner double seal joint, the double seal when being used for air conditioner indoor machine and being connected with outdoor unit.
Background technique
Air conditioner when mounted; Indoor set is connected through connecting tube with outdoor unit; The horn mouth of the copper sleeve sealing cone of indoor set and connecting tube one end is tightened sealing through copper nut, and the stop valve joint sealing conical surface of outdoor unit and the horn mouth of the connecting tube the other end are tightened sealing through copper nut.The existing technology connecting tube only adopts conical surface contact seal, air conditioner that the horn mouth conical surface seal was lost efficacy when connecting, or air conditioner poor sealing when installing, and causes air conditioner refrigeration or heating effect to descend.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art, a kind of employing double sealing structure to be provided, can greatly reducing because air conditioner causes the air conditioner double seal joint of coolant leakage at the poor sealing of installation process.
The technological scheme of the utility model air conditioner double seal joint is: comprise copper sleeve assembly and shut-off valve assemblies; The sealing cone of copper sleeve assembly and shut-off valve assemblies is connected mutually through the horn mouth of connecting tube; And tighten sealing by copper nut, and it is characterized in that being shaped on sealed groove separately on described copper sleeve assembly and the shut-off valve assemblies, seal ring is installed in the sealed groove; Seal ring contacts with the mouth inner wall of copper nut; In described two copper nut end inwalls, be shaped on the sealing caulking groove separately, O type circle is installed in the sealing caulking groove, O type circle contacts with copper sleeve assembly and shut-off valve assemblies outer wall respectively.
The air conditioner double seal joint of the utility model is respectively installed a seal ring on copper sleeve assembly and shut-off valve assemblies, two copper nut inwalls are also respectively installed an O type circle; During use; Connecting tube two ends copper nut respectively with copper sleeve assembly and shut-off valve assemblies threaded engagement, the joint sealing conical surface and the horn mouth of connecting tube are closely contacted form sealing, the O type circle on simultaneously in the copper nut contacts with the connecting tube outer wall; Seal ring on copper sleeve assembly and the shut-off valve assemblies contacts with the copper nut mouth inner wall; Form secondary seal, even conical surface seal lost efficacy, because the secondary seal of seal ring and O type circle has been arranged; Air-conditioner coolant can not revealed yet, and air conditioner refrigeration or heating effect are maintained a good state.
Description of drawings
Fig. 1 is the utility model air conditioner double seal joint structure schematic representation.
Embodiment
The utility model relates to a kind of air conditioner double seal joint, and is as shown in Figure 1, comprises copper sleeve assembly 1 and shut-off valve assemblies 2; The sealing cone of copper sleeve assembly 1 and shut-off valve assemblies 2 is connected mutually through the horn mouth of connecting tube 3; And tighten sealing by copper nut 4, and it is characterized in that being shaped on sealed groove 5 separately on described copper sleeve assembly 1 and the shut-off valve assemblies 2, seal ring 6 is installed in the sealed groove 5; Seal ring 6 contacts with the mouth inner wall of copper nut 4; In described two copper nuts, 4 end inwalls, be shaped on sealing caulking groove 7 separately, O type circle 8 is installed in the sealing caulking groove 7, O type circle 8 contacts with copper sleeve assembly 1 and shut-off valve assemblies 2 outer walls respectively.This programme is respectively installed a seal ring 6 on copper sleeve assembly 1 and shut-off valve assemblies 2; Two copper nut 4 inwalls are also respectively installed an O type circle 8, during use, connecting tube 3 two ends copper nuts 4 respectively with copper sleeve assembly 1 and shut-off valve assemblies 2 threaded engagement; The joint sealing conical surface and the horn mouth of connecting tube are closely contacted form sealing; O type circle 8 on simultaneously in the copper nut 4 contacts with connecting tube 3 outer walls, and the seal ring 6 on copper sleeve assembly 1 and the shut-off valve assemblies 2 contacts with copper nut 4 mouth inner walls, forms secondary seal; Even conical surface seal lost efficacy; Because the secondary seal of seal ring and O type circle has been arranged, and air-conditioner coolant can not revealed yet, air conditioner refrigeration or heating effect are maintained a good state.
