Abstract

The utility model discloses a connecting pipe structure for an air conditioning internal and external unit. The connecting pipe structure for the air conditioning internal and external unit comprises a stop valve connector, a connecting pipe and an internal unit connector, wherein one end of the connecting pipe is connected with the stop valve connector while the other end is connected with the internal unit connector, and flat connection is applied both between the connecting pipe and the stop valve connector and both the connecting pipe and the internal unit connector. The connecting pipe structure for the air conditioning internal and external unit has the advantages of easy installation and good sealing of connection. Furthermore, leakage problem caused by installation is reduced, and installation quality of an air conditioner is ensured.

Description

A kind of air-conditioning connection pipe for internal-external unit structure
Technical field
The utility model relates to a kind of air-conditioning parts, relates in particular to a kind of air-conditioning connection pipe for internal-external unit structure.
Background technology
The air-conditioning products volume is installed the result of use of fine or not direct relation air-conditioning, present domestic air conditioning is split type mostly, the installation of split-type air conditioner is mainly the connection of inside and outside machine, tube connector is connected inside and outside mechanism cold circulation system, so the tube connector installation quality mainly is subject to the impact of connection sealing.Traditional tube connector is connected and is connected by horn mouth with indoor and outdoor machine, sealing means is linear sealing, the horn mouth of inside and outside machine joint and copper pipe is fixed together by the active force of locking nut, the connection of in fact inside and outside machine joint and copper pipe is that the line on face coordinates, mainly by contact wire, seal, there is certain leakage problem in this sealing, the split-type air conditioner that adopts this horn mouth formula to connect, great majority need to add primary coolant every 2-3, otherwise, the effect attenuation ratio is larger, have again, the connected mode of this tube connector and joint installs the bad control of installation accuracy, this problem in horn mouth misalignment joint inclined-plane often occurs, thereby cause leakage problem more serious.The Chinese patent that application number is 200610014840.9 discloses a kind of connecting piping for air conditioner indoor and outdoor machine and has comprised tube connector, threaded sleeve and maintenance valve, threaded sleeve is arranged on the tube connector that is connected indoor set and off-premises station one side distributor or separating tube with maintenance valve, one end of maintenance valve connects the tube connector of off-premises station one side distributor or separating tube, the tube connector of other end connecting thread sleeve pipe one end, the other end of threaded sleeve connects the tube connector of indoor set import.The leakage problem of the connected mode of this tube connector and inside and outside machine joint is still to be improved.
Summary of the invention
The utility model mainly is to provide a kind of air-conditioning connection pipe for internal-external unit structure, easy for installation, and the good airproof performance of connection, reduced the leakage problem caused due to installation question, guaranteed the installation quality of air-conditioning.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: it comprises stop valve joint, tube connector, interior machine joint, described tube connector one end is connected with described stop valve joint, the other end is connected with described interior machine joint, between described tube connector and stop valve joint, be flat mouth between tube connector and interior machine joint and be connected.The utility model has adopted the flat mouth connected mode, and connection is more simple and convenient like this, in the difficulty that has reduced assembling, has guaranteed again sealing, has effectively reduced leakage problem.
As preferably, between described tube connector and stop valve joint, between tube connector and interior machine joint, be provided with lock nut.
As preferably, the endoporus of described lock nut is the cylinder straight hole.
As preferably, described stop valve joint is square joint, and termination, described tube connector two ends is flange flat mouth termination.
As preferably, on termination, described tube connector two ends, all overlap the hydrogenated nitrile-butadiene rubber gasket ring is arranged.
For the enhanced leaktightness performance, as preferably, on described stop valve joint and interior machine joint, be provided with O type circle.
As preferably, described tube connector is copper pipe or nylon plastic pipe.
While installing in order to meet, the extension requirement of corresponding pipe fitting, as preferably, be provided with bellows piece on described tube connector.
The beneficial effect that the utility model brings is, the utility model adopts the flat mouth connected mode, and it is easy for installation, and the good airproof performance of connection has reduced the leakage problem caused due to installation question effectively, has guaranteed the installation quality of air-conditioning.
