Abstract
A connecting part with a pipeline locking device includes a radiator supplementation core, an internal press nut and a rubber sealing ring. The utility model is characterized in that the internal side of the radiator supplementation core is serially provided with a rubber sealing ring with a taper, an axial stopping ring, and an internal press nut. As the interior of the radiator supplementation core is provided with the rubber sealing ring with a taper and a wedge-shaped axial stopping ring, in the screwing process of the internal press nut thread, the connecting pipe entering the radiator transversely ensures that the axial stopping ring gradually reduces the pipe diameter and tightly fixes to the connecting pipe; meanwhile, the rubber sealing ring is tightly pressed along the longitudinal direction of the connecting pipe and the connecting pipe is tightly fixed. The utility model has the advantages of simple and sound structure, construction application, long service life, wide application range, etc.
Description
Technical field
The utility model belongs to pipeline interconnection technique field, the link of the band pipeline locking device that specifically a kind of pipeline is connected with radiator.
Background technique
In heating pipeline connects, particularly in the connection pipe fitting of radiator and pipeline, generally adopt screw thread to connect firmly at present, labor intensity is big, and efficient is low.In recent years, a kind of " quick lock in pipe joint " appearred on the market, although this connection pipe fitting remedies above-mentioned deficiency to a certain extent, but owing to only come fastening and spacing by a rubber seal, then when the pressure of radiator is excessive, easily connecting tube is ejected, and have an accident.In addition, above-mentioned pipe joint also dare not use easily for the higher heating equipment of some relative pressures.
Summary of the invention
The purpose of this utility model provides a kind of link that can lock the band pipeline locking device of connecting pipeline in the radiator through hole.Connecting pipeline is not broken away from certain pressure range.
The purpose of this utility model is achieved in that it comprises radiator benefit core, interior pressure nut, rubber seal, it is characterized in that the inboard of mending core at radiator is disposed with the rubber seal of a band tapering, axial non-return ring, interior pressure nut.
Axial non-return ring of the present utility model is wedge shape and the axial non-return ring that has locking hole vertically.
The purpose of this utility model also is to bear the pressure needs according to radiator inside, then have screw thread in the inboard of axial non-return ring, make it when being anchored on connecting tube, its internal thread is pressed in the outer surface of connecting tube tightly, form the screw thread impression, thereby make and in certain pressure range, connecting tube can't be ejected.This novel structure is specially adapted to and being connected of nonmetal pipe fitting, as: plastic-aluminum pipe or plastic tube, because nonmetal pipe fitting outer surface hardness is relatively poor, the formed screw thread depth of cup, then more firm.
The utility model is owing to be provided with the rubber seal and the axial non-return ring of wedge shape (the awl mouth is provided with back-to-back with the wedge shape mouth) of a band tapering in the inside of radiator benefit core, in the process of interior pressure nut thread precession, with enter in the radiator connecting tube along laterally make axial non-return ring gradually undergauge it is anchored on the connecting tube; Meanwhile, rubber seal is compressed and be fastenedly connected pipe along vertical (by the transmission of axial non-return ring) of connecting tube.Characteristics such as this is novel also to have simple and reasonable, easy to use, sealing and good damping effect, the life-span is long, application area is wide.
The utility model is described in further detail below in conjunction with accompanying drawing, and this embodiment only is an example, and it will not limit scope of the present utility model.
Description of drawings
Fig. 1 is the structural representation sketch that partly cuts open of the present utility model
Embodiment
By shown in Figure 1, among the figure 1 mends core for radiator, be disposed with rubber seal 2, the wedge shape of a band tapering in the inboard that radiator is mended core 1 and have the axial non-return ring 3 (the awl mouth of rubber seal with axially the wedge shape mouth of non-return ring be provided with back-to-back) of locking hole 5 vertically, the inboard of this axial non-return ring also has screw thread, presses nut 4 in refilling at last.This structure is when using, earlier radiator is mended the inlet that core 1 is fastened on radiator, and then the pipeline that will be connected with radiator (metal tube or plastic-aluminum Guan Junke) inserts radiator by this structure, press nut 4 in the screw thread precession, then enter in the radiator connecting tube along laterally make axial non-return ring gradually undergauge it is anchored on the connecting pipeline, its internal thread is pressed in the outer surface of connecting tube tightly, forms the screw thread impression; Meanwhile, rubber seal is compressed and be anchored on the connecting pipeline along vertical (by the transmission of axial non-return ring) of connecting tube, thereby realized the purpose of this utility model.
