Abstract
The utility model relates to a plug-in spiral corrugated metal flexible coupling pipe. A main body is a metal corrugated pipe (1) processed with spiral corrugations; both ends are welded with coupling heads (2) carved with threads spirally coupled with a coupling nut (3); the other end of the coupling nut (3) is provided with a sealing ring (4). The utility model can be bent at will without being curved and can be directly plugged with a joint of the exiting gas coupling pipe with simple and reliable installation. The utility model can thoroughly stop the phenomena of gas leakage and gas block existed in the coupling of the original rubber pipe to eliminate the hidden danger of the accidents of poisoning and exploding events because of the gas leakage.
Description
The utility model relates to a kind of wavy metal connecting tube that is used to carry gas-liquid, particularly a kind of plug-in type helical fissure metal hose connector.
Along with after combustion gas such as town and country piped gas, rock gas, liquefied petroleum gas, biogas enter huge numbers of families, bring easy to use, the free of contamination again clean fuel of health to people, but for a long time, the connecting passage mode of these combustion gas between burning appliance is: tighten with Drop-proof with galvanized wire by the rubber pipe connection and at the two ends of rubber pipe; This Placement exists many defectives: install and transposing inconvenience, under bending state, block gas circuit easily, the rubber pipe corrosion-resistant, easily aging, working life is short, gas leak phenomenon takes place easily, in all parts of the countryly now a lot of gas poisoning or combustion gas that cause because of above-mentioned reason have taken place reveals explosive incident.For solving the safe and reliable connectivity problem of gas pipeline, we will notice that sight line transfers on the metal bellows, but existing metal bellows generally all is annular corrugated, there are bigger gap and ripple shallow between ring and the ring, thereby not flexible, be not suitable as the gas connection pipe that need have suitable ductility.
The purpose of this utility model just is to provide for the defective that overcomes above-mentioned prior art existence a kind of plug-in type helical fissure metal hose connector of safe and reliable connectivity problem of thorough solution gas pipeline.
The purpose of this utility model is achieved in that the main body of plug-in type helical fissure metal hose connector is one to be processed to have the metal bellows of helical fissure, its two ends are welded with the connecting head that is carved with screw thread and are threaded with a coupling nut, and the other end of coupling nut is provided with a seal ring.
Compared with prior art, the utility model is can be arbitrarily crooked and don't can bend, and can directly peg graft with existing coal gas connecting tube joint, simple installation, reliable, can thoroughly stop former rubber tube and connect gas leakage, the choke phenomenon that exists, thereby eliminate the accident potential that causes poisoning, explosive incident because of the combustion gas leakage.
Description of drawings:
Fig. 1 is the utility model embodiment's a structural representation (broken section).
Fig. 2 is part (connection end) enlarged view of Fig. 1.
Fig. 3 is the optimum structure schematic representation (analysing and observe) of seal ring (4) in the utility model.
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the main body of helical fissure metal hose connector is one to be processed to have the metal bellows (1) of helical fissure, its two ends are welded with the connecting head (2) that is carved with screw thread, connecting head (2) is threaded with coupling nut (3), the other end of coupling nut (3) is provided with a seal ring (4), for corresponding its interior hole shape with existing gas kitchen pipe joint (5) can have certain taper, shown in Fig. 2,3.
When installing and using, as shown in Figure 1, 2, gas kitchen pipe joint (5) directly is inserted in the connecting head (2) by coupling nut (3) mouth, tightens coupling nut (3), gas kitchen pipe joint (5) will be close to fixing down and sealing at the radial deformation of seal ring (4).
For making sealing effect better, described seal ring (4) is preferably shape as shown in Figure 3, be that its interior edge face slightly outwards convexes into a tapering end face, its role is to, when coupling nut (3) was tightened in installation, seal ring (4) was paid except radially also will axial deformation taking place in described tapering end the deformation, connecting head (2) end face and seal ring (4) are close to produce sealing, this moment, described tapering end face flattened, as shown in Figure 2.
For guaranteeing the ductility of plug-in type helical fissure metal hose connector, its helical fissure degree of depth (i.e. (D-Di)/2) is the best with 1.0～5.0mm, the pitch of waves (being q, under the nature) with 0.5～5mm.
Though invention of the present utility model comes from the safe and reliable connectivity problem that solves gas pipeline, as seen from above-mentioned, application of the present utility model is not limited to this field, and is equally suitable in the field of carrying other gas-liquids.
Claims (3)
