Description
Technical field:
The utility model relates to a kind of clamping hoop type fuel gas conduits.
Background technique:
Stainless steel metal bellows is installed in liquid conveying system as a kind of flexible pressure-resistant pipe fitting, to compensate pipeline
Or the mutual displacement of machine, equipment connecting pin, absorb vibrational energy, the effects of vibration damping, noise reduction can be played, have it is flexible,
The multinomial feature such as light weight, corrosion-resistant, antifatigue, high-low temperature resistant.The existing stainless steel metal bellows for fuel gas conduit its
Structure is usually if 204226887 U of patent No. CN, patent name are the stainless steel metal fuel gas conduit institute for domestic gas system
As open, the connector at both ends needs to rotate together together with entire stainless steel metal bellows in connection, certain narrow
Place connection is inconvenient.
Utility model content:
Technical problem to be solved by the utility model is to provide a kind of clamping hoop type fuel gas conduits for facilitating connection.
The technical solution of the utility model is to provide a kind of clamping hoop type fuel gas conduit, including stainless steel metal bellows,
Stainless steel metal bellows both ends pass through straight pipe respectively and are equipped with collar nut, and collar nut includes hex nut ontology and position
The aperture of connector in hex nut ontology one end, connector makes connector be socketed in straight tube slightly larger than the outer diameter of straight pipe
It can rotate in section and relative to straight pipe, the ring-shaped rubber gasket with through-hole is equipped in hex nut ontology, rubber sheet gasket
Internal diameter is matched with the outer diameter at straight tube end, and the outer end of straight pipe is also equipped with position limiting convex ring, and the outer diameter of position limiting convex ring is greater than connector
Aperture.
After using the above structure compared with prior art, the utility model has the advantage that by stainless steel metal
Mobilizable positioning joint nut is arranged in bellows both ends, facilitates connection, and when connection only needs to be rotatablely connected nut, is not required to
Rotate stainless steel metal bellows.
Preferably, position limiting convex ring and straight pipe are integrally formed by mold.
Preferably, stainless steel metal bellows surface is coated with corrosion resistant plastic-spraying layer.
Detailed description of the invention:
Fig. 1 is the explosive view of the utility model.
Fig. 2 is the structural schematic diagram of the utility model.
Fig. 3 is the half sectional view of the utility model.
Fig. 4 is the collar nut structural schematic diagram of the utility model.
Specific embodiment:
The utility model is described in further detail with reference to the accompanying drawings and detailed description:
As shown in Figs 1-4, a kind of clamping hoop type fuel gas conduit, including stainless steel metal bellows 1, stainless steel metal bellows 1
Both ends are integrally extended with straight pipe 2, and collar nut 3 is equipped on straight pipe 2, and collar nut 3 includes 31 He of hex nut ontology
The aperture of connector 32 positioned at hex nut ontology one end, connector 32 is socketed connector slightly larger than the outer diameter of straight pipe
It can rotate on straight pipe and relative to straight pipe, the ring-shaped rubber gasket 4 with through-hole, rubber are equipped in hex nut ontology 31
Glue gasket 4 is bonded with connector inner end, and offsets to form sealing structure with hex nut inner body wall, the internal diameter of rubber sheet gasket 4
It is matched with the outer diameter of straight pipe, after being arranged collar nut, is also equipped with position limiting convex ring 5 in the outer end of straight pipe, position limiting convex ring 5
Outer diameter is greater than the aperture of connector, position limiting convex ring 5 and straight pipe 2 and is integrally formed by mold, i.e., position limiting convex ring is by stainless steel gold
The straight pipe for belonging to bellows passes through mold extrusion forming.
In view of use environment, to improve anticorrosion effect, stainless steel metal bellows surface is coated with corrosion resistant spray
Mould layer.The surface plastic spraying layer formed by Electrostatic Spray Technology, charges plastic powders using electrostatic generator, is adsorbed on metal
Then hose surface passes through 180~220 DEG C of baking, so that powder fusing is attached on metal surface, form surface plastic spraying layer, increase
The ability of the strong anti-external environment corrosion of corrugated flexible hose.
By the way that mobilizable positioning joint nut is arranged at stainless steel metal bellows both ends, facilitate connection, when connection
It needs to be rotatablely connected nut, does not need rotation stainless steel metal bellows.
Only the utility model preferred embodiment is described above, but is not to be construed as the limit to claim
System.All equivalent structure or equivalent flow shifts done using the utility model specification and accompanying drawing content are included in this
Within the scope of patent protection of utility model.
