Abstract
The utility model discloses an expansion joint installed in heating systems. Fittings are arranged between a radiator and a pipeline, and plasticity sealing fillers, telescopic pipes, etc. are arranged in fitting bodies. Under the action of compression nuts, the fillers are deformed so that sealing effects are formed.
Description
The utility model is in the heating system, and the spare and accessory parts that radiator connects with pipeline are series of products, and suitable caliber is: 1 cun, 6 minutes and 4 minutes.
Radiator connects the general three kinds of accessories that adopt in the system of heating at present with pipeline: " bushing ", " short silk ", " movable joint ".Bushing directly connects with radiator, to adapt to different calibers; Short silk connects bushing and movable joint, and for easy installation and removal, bushing is leaned on thread connection with weak point silk, short silk with alive merithal.Sealing between screw thread is to guarantee by the fine oil of flax silk or other filler, exists the numerous rope of operation like this, leaks easily, and the connecting tube dimensions length requires than shortcomings such as essences.
Provide a kind of accessory, it can not only play the effect of original accessory order of the present utility model, and can simplify installation procedure, can also reduce the leakage link.
The purpose of this utility model is achieved in that accessory adopts cast iron, one end is the screw thread that matches with radiator, the other end is processed with internal thread, sealing material (heat resistant rubber) clamp nut and telescoping tube are housed, telescoping tube one end has screw thread, accessory is connected on the radiator during installation, and the other end connects other accessories such as valve or elbow by telescoping tube, also telescoping tube can be removed directly to connect with pipeline.Screw clamp nut then, make the filler distortion, play sealing function.Because telescoping tube is arranged, or pipeline directly inserts, so the relatively good grasp of the installation dimension of pipeline.
Said structure has guaranteed connecting of pipeline and radiator very easily, simplifies the structure, and has reduced leakage.
Below in conjunction with accompanying drawing the utility model is further specified.
1 is fittings body among the figure, the 2nd, and clamp nut, the 3rd, airtight and watertight padding, the 4th, telescoping tube.
Telescoping tube in the drawings is through and is placed in the airtight and watertight padding in the fittings body at the clamp nut of packing into.After screwing clamp nut, the filler distortion seals.
Claims (2)
1, pipeline and the joining joint of radiator in a kind of heating system are made up of connected body, airtight and watertight padding, clamp nut, telescoping tube.It is characterized in that: airtight and watertight padding, telescoping tube and clamp nut are housed in the fittings body.
2, joint according to claim 1 is characterized in that airtight and watertight padding is a ring-shaped rubber ring, is enclosed within on the telescoping tube, and telescoping tube has certain size length, adjustable position.
