Description
Technical field
The invention belongs to valve design field, more particularly to a kind of air-conditioning connection pipe for internal-external unit road piecing devices.
Background technology
At this stage, in the installation of air-conditioning internal-external machine, it is necessary to the loudspeaker at the company's of processing machine pipe both ends in advance before both connect
Mouthful, connection is tightened by the connection valve or silk head of the subsidiary nut of even machine pipe and air-conditioner host during installation, the loudspeaker of the company's of utilization machine pipe
Mouth sphere forms sealing surface with the sphere of connection valve or silk head.So as to complete the connection of air-conditioning internal-external machine system sealing.
But there are following various problems in such connected mode：
1. connecting machine pipe needs to process in advance, stores.Increase processing, transport, staff training, equipment investment, management cost.
2. horn mouth inner face requires smooth no marking, it otherwise can cause to leak slowly, easily cause customer complaint, serious infringement
The quality public praise of enterprise.
3. when mounted, easily cause to damage because of dislocation or leak between Lian Jiguan nut and valve or silk head.Especially
In work high above the ground, it is easier to problems occur.
The content of the invention
The technical problem to be solved in the present invention be how overcome the deficiencies in the prior art, there is provided a kind of connection of air-conditioning internal-external machine
Pipe joint unit.
The technical scheme that uses to achieve the above object of the present invention is：Air-conditioning connection pipe for internal-external unit road piecing devices, including
Joint gland, nut, back-up ring, gripping block, spring washer, metallic gasket, O-ring seal, cylindrical seal circle, joint gland
Be equipped with the middle part of nut by hole, to through connection air-conditioning indoor and outdoor machine pipeline, the inside of its center tap gland
Provided with shoulder hole, to penetrate the pipeline of connection air-conditioning indoor and outdoor machine, cylindrical seal circle is arranged on the bottom of shoulder hole, insertion
The head of pipeline is withstood on cylindrical seal circle, and the pipeline external for being enclosed on insertion is followed successively by metallic gasket, O-ring seal, spring
Packing ring, gripping block and back-up ring, and in the shoulder hole of joint gland, nut is through on the pipeline of insertion joint gland,
And screw fastening by the screw thread of joint gland side, while by gripping block, metallic gasket, spring washer, O-shaped sealing
Circle and cylindrical seal circle are pressed on the inside of joint gland.
Further, the gripping block includes the head of truncated cone-shaped and is integrally formed the cylindrical tail portion in head tail end,
The middle part of gripping block formed with to through connection air-conditioning indoor and outdoor machine pipeline through hole.
Further, the medial surface of the head opening of the joint gland is in the conical surface and the side phase of the gripping block
Match somebody with somebody.
Further, the gripping block is combined by two pieces of symmetrical clamping components and formed.
The present invention changes the lock portion of the design of air-conditioning duct connector, increase sealing and Lian Jiguan, even machine pipe
Need erecting bed to clean, direct Fast Installation, have further the advantage that simultaneously：
1. improving in-site installation efficiency, as long as even valve port or silk head will be inserted machine pipe, clutch
2. connecting machine pipe without factory process, artificial, material, storage, management cost are saved
3. the leakage quality problems brought when effectively reducing installation operation, reducing mass loss, it is horizontal to improve enterprise-quality.
4. it can directly substitute the disengaging pipe joint with existing indoor apparatus of air conditioner；Can triple valve existing with existing outdoor unit, cut-off
Valve is designed to a kind of new triple valve, stop valve.
Brief description of the drawings
Fig. 1 attachment structure sectional views of the present invention.
Embodiment
Below in conjunction with the accompanying drawings, the present invention is described in further detail：
As shown in figure 1, air-conditioning connection pipe for internal-external unit road piecing devices, including joint gland 1, nut 2, gripping block 3, gear
The middle part of circle 4, metallic gasket 5, spring washer 9, O-ring seal 6, cylindrical seal circle 7, joint gland 1 and nut 2 is equipped with
Circular hole, to through the pipeline 8 of connection air-conditioning indoor and outdoor machine, the inside of its center tap gland 1 is provided with shoulder hole 11, to wear
Enter to connect the pipeline 8 of air-conditioning indoor and outdoor machine, cylindrical seal circle 7 is arranged on the bottom of shoulder hole, and the head of the pipeline 8 of insertion is withstood on
On the end face of cylindrical seal circle 7, what the outside of the pipeline 8 of insertion was inserted in is followed successively by metallic gasket 5, O-ring seal 6, spring pad
Circle 9, gripping block 3 and back-up ring 4 (i.e. by inside to the outside direction of joint gland be followed successively by cylindrical seal circle 7, metallic gasket 5,
O-ring seal 6, metallic gasket 5, gripping block 3 and back-up ring 4), and remain in the shoulder hole 11 of joint gland 1, nut 2
It is through on the pipeline 8 of insertion joint gland 1, and carries out screwing fastening by the screw thread of the side of joint gland 1, while will folder
Tight block 3, metallic gasket 5, spring washer 9, O-ring seal 6 and cylindrical seal circle 7 are pressed on the inside of joint gland 1.
