Description

It is a kind of can Fast Installation or dismounting metal hose joint application method
Technical field
The present invention relates to it is a kind of can Fast Installation or dismounting metal hose joint application method.
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.
The content of the invention
The present invention needs to solve the problems, such as to be to be directed to above-mentioned the deficiencies in the prior art, and providing one kind Fast Installation or can tear open The application method of the joint of the metal hose unloaded.
In order to solve the above technical problems, the technical solution adopted by the present invention is:
It is a kind of can Fast Installation or dismounting metal hose joint application method, comprise the following steps:
(1)When being socketed female joint with sub- joint, sub- joint is first assembled, rubber ring is inserted in the seal groove at end;
(2)The end of being inserted in of sub- joint is inserted in the socket end of female joint, by claw alignment guide groove, arc is inserted to along guide groove One end of groove, then gyrator joint, making claw, arcuately groove is rotated to stopper slot root, then is pulled outwardly mover joint, by claw Stopper slot head is pulled to by stopper slot root;
(3)Lock groove now is formed between the shoulder rank of sub- joint and socket end, jump ring, which is connected in lock groove, can complete mother The socket of joint and sub- joint;
(4)When dismantling female joint and sub- joint, the jump ring first dismantled in lock groove;
(5)Then inside hairclipper joint, claw is pushed into stopper slot root, then gyrator joint by stopper slot head, by claw Guide groove root is threaded to by stopper slot root, last outwards rock joint and is pulled out claw by guide groove, completes female joint and son The dismounting of joint.
The quantity of seal groove has 2, is respectively arranged on the both sides of claw.
The depth of neck is less than or equal to the half of female joint wall thickness.
The madial wall of socket end is provided with 3 necks, and 3 neck annulars are distributed on the madial wall of socket end.
The vertex chamfering of claw.
Compared with prior art, the beneficial effects of the invention are as follows:Claw inserts one end of deep-slotted chip breaker along guide groove, then along arc Shape groove is rotated to stopper slot root, then is pulled to stopper slot head by stopper slot root, clamping jump ring in lock groove, the width of jump ring Equal to the longitudinal length of stopper slot, you can female joint and sub- joint are connected together, clamping and dismounting are all very convenient, are inserted in Annular seal groove on the outer peripheral face at end, seal groove is interior to be provided with rubber ring, it is ensured that the sealing effectiveness after clamping.
