Abstract
The utility model belongs to a pipe joint, in particular to a movable joint for the connection of the aluminium-plastics pipe piece. The movable joint for aluminium-plastics pipe piece of the utility model comprises a connecting body, sealing gaskets, a snap ring, and locking nuts; wherein, the connecting body is a cavity columnar structure, and the two ends of the cavity columnar structure are provided with thread bosses; the connecting body is sheathed outside the two plastic-aluminum tube pipes which are connected together, and the sealing gaskets are respectively arranged between the two ends of the connecting body and the two plastic-aluminum pipes; the outside of the sealing gasket is provided with a compacting gasket, and the snap ring is tightly contacted with the compacting gasket and is sheathed on the plastic-aluminum pipe; the locking nuts are sheathed on the thread bosses on the two ends of the connecting body. The movable joint for aluminium-plastics pipe piece has the advantages that the installation is time-saving and labor-saving, the operation and the repair are convenient; the connection of the pipe pieces can be realized, meanwhile, the pipe pieces can be locked.
Description
Technical field
The utility model belongs to a kind of pipe fitting joint, specifically is a kind of union that the plastic-aluminum pipe fitting connects that is used for.
Background technique
The Placement of existing plastic-aluminum pipe fitting mostly adopts connected to connect, when the accessory on the pipeline needs repairing, for example change the valve on the pipeline, take apart pipe fitting more change jobs finish after, when the pipe fitting that adopts this Placement to connect connects again, the problem of sealing difference appears in the meeting that has, the connection again that then can't realize pipe fitting that has.Cause very big trouble to maintenance work.The jointing of existing plastic-aluminum pipe fitting exists structure complicated, problem such as not easy to operate during use.
Summary of the invention
The utility model has solved that existing plastic-aluminum pipe is difficult for after maintenance that realization connects again and existing plastic-aluminum tubing coupling structure is complicated, not easy-operating technical problem during use, provide a kind of simple in structure, easy to operate, can make existing plastic-aluminum pipe after maintenance, can realize the jointing that excellent sealing connects.
The purpose of this utility model is achieved in that the union of a kind of plastic-aluminum pipe fitting, include connecting body, sealing gasket, snap ring, locking nut, wherein connecting body is the cavity column structure that two ends are threaded boss, connecting body is enclosed within outside two sections plastic-aluminum pipes that join, between connecting body two ends and two sections plastic-aluminum pipes sealing gasket is housed respectively, sealing gasket is provided with clamping pad outward, and snap ring is close to clamping pad and is enclosed within on the plastic-aluminum pipe, and locking nut is sleeved on the screw boss at connecting body two ends.
The two ends place of connecting body inner chamber of the present utility model is provided with concave station respectively, and sealing gasket is fixed.Sealing gasket of the present utility model is a cone structure, can make favorable sealing property.Snap ring of the present utility model is an open type, is convenient to the dismounting of plastic-aluminum pipe.
The beneficial effects of the utility model are: install save time, laborsaving, maintenance operation is convenient, is realizing reaching the locking purpose again when pipe fitting connects.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure, plastic-aluminum pipe fitting of the present utility model union, include connecting body 1, sealing gasket 2, snap ring 3, locking nut 4, wherein connecting body 1 is threaded the cavity column structure of boss for two ends, the two ends place of connecting body 1 inner chamber is provided with concave station respectively, 6 one sections ends that are enclosed within connecting body 1 of two sections plastic-aluminum pipes that join, another section is enclosed within the other end of connecting body 1, between connecting body 1 two ends and two sections plastic-aluminum pipes 6 sealing gasket 2 is housed respectively, sealing gasket 2 is a cone structure, material is a rubber material, sealing gasket 2 is packed in the concave station at connecting body with matching 1 inner chamber two ends place, and guarantee good sealing property.Be provided with clamping pad 5 outside the sealing gasket 2, snap ring 3 is close to clamping pad 5 and is enclosed within on the plastic-aluminum pipe 6, and snap ring 3 is an open type, is convenient to the dismounting of plastic-aluminum pipe 6.Locking nut 4 is sleeved on the screw boss at connecting body 1 two ends, and connecting body 1 and plastic-aluminum pipe 6 are connected as one, and realizes the locking purpose.Other materials such as that other Component of plastic-aluminum pipe fitting of the present utility model union can adopt as required is copper, stainless steel.
During use, two sections plastic-aluminum pipe 6 sockets that the two ends of the connecting body 1 in the plastic-aluminum pipe fitting of the present utility model union are joined with needs respectively, again sealing gasket 2, clamping pad 5, snap ring 3 are set in the concave station at the two ends place that makes sealing gasket 2 and clamping pad 5 embedding connecting bodys 1 inner chamber on the plastic-aluminum pipe 6, and after making snap ring be close to clamping pad 5, with locking nut 4 connecting body 1 and plastic-aluminum pipe 6 are connected as one, and locking.
The utility model can be used for the connection again after the existing plastic-aluminum pipe fitting maintenance, the connection when also can be used for first dress plastic-aluminum pipe fitting, in the future the maintenance of being more convenient for like this.The utility model can be used for productive life water pipeline and heating pipe.
