Description
Technical field
The present invention relates to a kind of joint of metal hose.
Background technology
The mode of the gas appliances such as traditional connection LP gas cylinder, Gas Pipe or gas-cooker is to be connected by rubber tube
Connect and tightened at the both ends of rubber tube with galvanized wire with anti-dropout；This connected mode there is it is many defects of：Installation and exchange
Inconvenience, gas circuit is easily blocked under bending state, rubber tube corrosion-resistant, easy to aging, service life is short, and gas leakage easily occurs
Phenomenon, thus the leakage of various coal gas, combustion gas can be triggered to cause the accident.Asked to solve the safe and reliable connection of gas pipeline
Topic, it is domestic to occur using corrugated metal pipe as main body in succession, there is certain flexible bendable without bending, threaded connection side
It can lean on, can thoroughly prevent gas leakage, choke phenomenon, it is actual so as to largely reduce the generation of gas leakage accident
Effect is fine.The junction portion of the combustion gas end used at present also uses matched thread joint arrangement, but its zero
Part is more and smaller, once installation is inconvenient, has lacked some parts will have very big potential safety hazard.
Metal hose is one of equipment installation, the major part connected between part, and it has flexible, high temperature resistant, resistance to
The characteristics of burn into pressure-bearing is higher.Therefore, it is able in Aero-Space, machine-building, petrochemical industry, electric power, metallurgy, construction industry etc.
Extensive use.Metal hose is typically made up of parts such as corrugated stainless steel tubing, net, retaining ring, adapter, weld-ring, joints, joint bag
Nipple and bump joint are included, there is fixed and loop type.Existing metal hose production technology typically uses will
The integrally molded completion of bellows, webmaster, retaining ring, then with adapter or weld.Another connected mode is bellows two
End is first welded with adapter, then net is enclosed on bellows both ends, and net is pressed in adapter with retaining ring and welded, then takes over and connects
Pipe welds.
The mode of production of above-mentioned metal hose could be realized by multi-pass welding, because welding produces substantial amounts of heat,
The difference of the wall thickness of each part and material in addition, cause welding position change in shape and thermal stress to concentrate, cause metal material
Structure produce change, reduce the mechanical strength of product.Therefore, existing metal hose service life is shorter, welding sequence
Complexity, low production efficiency, cost are high, are not suitable for producing in enormous quantities.
Chinese patent 200810061017.2 discloses a kind of metal hose, is integral loop metal flexible pipe and assembling side
Method.The flexible pipe includes bellows, straight tube, metal net cover, and the straight tube that bellows is connected is integrated, and its designing points is directly
Pipe, metal net cover, metal retaining ring are that integral type penetrates kink joint, and expose in single flange and be arranged on described kink joint
One side.Assemble method is that two sides of single flange or double-turnup are coupled by corresponding supporting kink joint respectively.This hair
The bright technical problem for solving hose coupling connection, assemble method are feasible.Its advantage is：With strong applicability, service life is longer,
Assembling is quick.It is low with production efficiency height, cost, the characteristics of being adapted to relatively produce in enormous quantities, connected between equipment installation, part
Ideal auxiliary equipment.But the design also owes preferable there is the connection of deficiency, especially hose coupling.
Application No. 201110272315.8 discloses a kind of snap joint of metal hose, includes a joint body,
It has one can hold the jack that corrugated flexible metal tube inserts from back to front.In the jack, groove seals circle is disposed with,
Spiral fastener, tighten up cutting ferrule.Wherein groove seals circle is arranged on bottom in joint body, the corrugated flexible metal tube rotation
The close contact of groove seals circle and its head for entering when in joint body and bottom are completely sealed in groove sealing ring, are sealed
Effect is strengthened.The spiral fastener being arranged on the outside of joint body on boss, the spiral fastener are made by way of screwing
The compression seal of its bottom carries out clamping, spacing to corrugated flexible metal tube.The joint body rearward end is tightened up provided with one
Cutting ferrule is sealed and fixed to the corrugated flexible metal tube by way of screwing.Its advantage is：Bonding strength after assembling
It is remarkably reinforced, but its shortcoming is：Sealing effectiveness is undesirable.
