Description

A kind of connector of metal hose
Technical field
The present invention relates to a kind of connectors of metal hose.
Background technique
The mode of the gas appliances such as traditional connection LP gas cylinder, fuel gas conduit or gas-cooker is to be connected by rubber tube It connects and is tightened at the both ends of rubber tube with galvanized wire with anti-dropout;This connection type is haveed the defects that many: installation and exchange Inconvenience is easy obstruction gas circuit under bending state, and rubber tube poor corrosion resistance, easy to aging, service life is short, is easy to happen gas leakage Thus phenomenon can cause various coal gas, the leakage of combustion gas causes the accident.It is asked to solve the safe and reliable connection of gas pipeline Topic, it is domestic to occur using based on corrugated metal pipe in succession, have certain flexible bendable without bending, threaded connection side It can lean on, can thoroughly prevent gas leakage, choke phenomenon, so that the generation of gas leakage accident is largely reduced, it is practical Effect is fine.The junction portion of combustion gas end used at present also uses matched thread joint arrangement, but its zero Component is more and smaller, and installation is inconvenient, once very big security risk will be had by having lacked some components.
Metal hose is one of equipment installation, the major part connected between component, it has flexible, high temperature resistant, resistance to The higher feature of burn into pressure-bearing.Therefore, it is able in aerospace, machine-building, petrochemical industry, electric power, metallurgy, construction industry etc. It is widely applied.Metal hose is generally made of parts such as corrugated stainless steel tubing, net cover, retaining ring, adapter tube, weld-ring, connectors, connector packet Nipple and bump joint are included, there is fixed and loop type.Existing metal hose production technology generally uses will
The integrally molded completion of bellows, network management, retaining ring, then with adapter tube or weld.Another connection type is ripple Pipe both ends are first welded with adapter tube, then net cover is covered at bellows both ends, and net cover is pressed on adapter tube with retaining ring and is welded, is then taken over It is welded with adapter tube.
The production method of above-mentioned metal hose is just able to achieve by multi-pass welding, since welding generates a large amount of heat, The difference of the wall thickness of each part and material in addition causes welding position change in shape and thermal stress to concentrate, leads to metal material Structure generate variation, reduce the mechanical strength of product.Therefore, existing metal hose service life is shorter, welding sequence Complexity, production efficiency are low, at high cost, 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 hose includes bellows, straight tube, metal net cover, and the straight tube that bellows is connected is integrated, and designing points are directly Pipe, metal net cover, metal retaining ring are that integral type penetrates loop connector, and in single flange exposing the loop connector is arranged in One side.Assemble method is that two sides of single flange or double-turnup are coupled by corresponding matched loop connector respectively.This hair Bright to solve the technical issues of hose coupling connection, assemble method is feasible.Its advantage is that: with strong applicability, service life is longer, Assembling is quick.It with high production efficiency, at low cost, suitable the characteristics of relatively producing in enormous quantities, is connected between equipment installation, component Ideal auxiliary equipment.But there is also deficiency, the especially connections of hose coupling to owe ideal for the design.
Application No. is 201110272315.8 to disclose a kind of quick coupling of metal hose, includes a joint body, It has one can hold the jack that corrugated flexible metal tube is inserted into from back to front.In the jack, it is disposed with groove seals circle, Spiral fastener tightens cutting ferrule.Wherein bottom end, the corrugated flexible metal tube rotation is arranged in joint body in groove seals circle The groove seals circle of when entering in joint body and bottom end is in close contact and its head is completely sealed in groove sealing ring, is sealed Effect is reinforced.Spiral fastener on boss is set on the outside of joint body, and the spiral fastener is made by way of screwing The compression sealing element of its lower end carries out clamping, limit to corrugated flexible metal tube.The joint body rear end is equipped with a tightening Cutting ferrule is sealed and fixes to the corrugated flexible metal tube by way of screwing.Its advantage is that: the bonding strength after assembling It is remarkably reinforced, but the disadvantage is that: sealing effect is undesirable.
Summary of the invention
Problem to be solved of the present invention is in view of the above shortcomings of the prior art, and to provide a kind of connecing for metal hose Head.
In order to solve the above technical problems, the technical solution adopted by the present invention is that:
