Description
Technical field
The utility model belongs to valve design field more particularly to a kind of air-conditioning connection pipe for internal-external unit road connector dress
It puts.
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 the two connection
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 spherical surface forms sealing surface with the spherical surface 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 for such connection mode：
1. connecting machine pipe needs to process in advance, store.Increase processing, transport, staff training, equipment investment, management cost.
2. horn mouth inner face is required to be smooth no marking, no it will cause slow leakage, customer complaint is be easy to cause, serious damage
The quality public praise of enterprise.
3. when mounted, between the nut of Lian Jiguan and valve or silk head, easily cause to damage due to dislocation or leak.Especially
In working at height, it is easier to problems occur.
The content of the invention
The technical problems to be solved in the utility model is how to overcome the deficiencies of the prior art and provide a kind of air-conditioning internal-external machine
Connecting pipe piecing devices.
The utility model to achieve the above object the technical solution adopted is that：Air-conditioning connection pipe for internal-external unit road piecing devices,
Including connector gland, nut, baffle ring, gripping block, spring washer, metal gasket, O-ring seal, cylindrical seal circle, connector is solid
Determine to be equipped in the middle part of head and nut through hole, with to pass through connection air-conditioning indoor and outdoor machine pipeline, center tap gland
Stepped hole is internally provided with, to penetrate the pipeline of connection air-conditioning indoor and outdoor machine, cylindrical seal circle is mounted on the bottom of stepped hole, inserts
The head of the pipeline entered is withstood on cylindrical seal circle, be sleeved on insertion pipeline external be followed successively by metal gasket, O-ring seal,
Spring washer, gripping block and baffle ring, and in the stepped hole of connector gland, nut is through the pipeline of insertion connector gland
On, and the screw thread for passing through connector gland side screw fastening, while by gripping block, metal gasket, spring washer, O-shaped
Sealing ring and cylindrical seal circle are pressed on the inside of connector 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 through hole with the pipeline to pass through connection air-conditioning indoor and outdoor machine is formed in the middle part of gripping block.
Further, the medial surface of the head opening of the connector 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 utility model changes the design of air-conditioning duct connector, increases sealing and the lock portion of Lian Jiguan, even machine
Pipe only needs erecting bed to clean, and direct Fast Installation has further the advantage that simultaneously：
1. improving in-site installation efficiency, as long as even valve port or silk head will be inserted into 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 reduce mass loss, it is horizontal to improve enterprise-quality.
4. it can directly substitute the disengaging pipe fitting with existing air conditioner indoor unit；Triple valve, cut-off can be showed with existing outdoor unit
Valve is designed to a kind of new triple valve, shut-off valve.
Description of the drawings
Fig. 1 the utility model connection structure sectional views.
Specific embodiment
Below in conjunction with the accompanying drawings, the utility model is described in further detail：
As shown in Figure 1, air-conditioning connection pipe for internal-external unit road piecing devices, including connector gland 1, nut 2, gripping block 3, gear
The middle part of circle 4, metal gasket 5, spring washer 9, O-ring seal 6, cylindrical seal circle 7, connector gland 1 and nut 2 is equipped with
Circular hole, with the pipeline 8 to pass through connection air-conditioning indoor and outdoor machine, center tap gland 1 is internally provided with stepped hole 11, to wear
Enter to connect the pipeline 8 of air-conditioning indoor and outdoor machine, cylindrical seal circle 7 is mounted on the bottom of stepped 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 metal gasket 5, O-ring seal 6, spring pad
Circle 9, gripping block 3 and baffle ring 4 (i.e. by inside to the outside direction of connector gland be followed successively by cylindrical seal circle 7, metal gasket 5,
O-ring seal 6, metal gasket 5, gripping block 3 and baffle ring 4), and remain in the stepped hole 11 of connector gland 1, nut 2
It is through on the pipeline 8 of insertion connector gland 1, and the screw thread for passing through 1 side of connector gland carries out screwing fastening, while will folder
Tight block 3, metal gasket 5, spring washer 9, O-ring seal 6 and cylindrical seal circle 7 are pressed on the inside of connector gland 1.
