Description
Technical field
The present invention relates to a kind of pipe fitting, particularly a kind of for fire fighting supply, combustion gas, heat, drink hot and cold water, draining,
The metallic conduit snap ring-type attachment structures such as air conditioner water, compressed air and penetration pipe, this snap ring-type attachment structure can reduce installation
Cost improves installation effectiveness and can strengthen the safety and reliability that pipeline connects.
Background technology
Along with accelerated development and the mutual reference in domestic and international constructed field of science and technology, nearly ten years rustless steel,
Copper, carbon steel tubing clamp-press type pipe all use thin at house or the running water pipe of building or other fluid conveying metallic conduits
Wall pipe designs, and owing to have employed thin wall-type, tubing own wt is light, substantial saving in material, is particularly well-suited to high-rise building
Pipe arrangement, and construction is simple, and the operating time is short, and joint non-threaded connects, without complicated mantle fiber operation, without high temperature naked light, solderless
Processing before and after when connecing, pollute without greasy dirt dye when construction cutting or linking or welding slag, crimp with specific purpose tool, pipe fitting connects wink
Between complete.
But in the fire-fighting spraying pipeline system of building, corrosion resistance is strong, service life length clamp-press type copper pipe and
The high-end tubing such as jam-on stainless steel pipe cannot be introduced into fire-fighting spraying pipeline system because price is high, so that Fire Protection Card pressure type now
Connecting pipeline, still continued to use the zinc-plated light-wall pipe of carbon steel material, connected mode still uses clamp-press type, and cartridge connection is stainless
Steel pipe has embodied the cost performance of height with utilization on copper pipe！Because rustless steel and copper pipe inherently have the strongest corrosion resistance
Can be long for service life with pipeline, the features such as attachment security is reliable, but the zinc-plated carbon steel pipe of fire-fighting uses cartridge connection to be used in
Spraying system of fire fighting exists the biggest defect and hidden danger.
In cartridge connection, crimping tool crimps at socket section and seal groove two simultaneously, and seal groove position is subject to
To compression, forcing the O RunddichtringO in groove to be close to steel pipe, play the effect of hermetic seal, socket section is by hexagonal card pressure, steel pipe
With pipe fitting crimp, utilizing the rigidity of metal material itself, play anti-pulling effect, card pressure technology is highly developed at rustless steel
Praised highly by the whole world with in the connection of copper tube, be used in the drinking water of hospital, star hotel and high-end residential in large quantities
Engineering, but utilize card pressure technology will there is the biggest defect and hidden danger on the zinc-plated carbon steel pipe of fire-fighting spraying！Owing to card is pressed
Formula pipe fitting socket section by hexagonal card pressure, steel pipe and the deformation of pipe fitting friction and Extrusion, cause coating steel pipe outer wall and pipe fitting inner wall
Zinc coat is destroyed, and the current in pipeline are by intubating inflow in gap, through hexagonal crimp position, now steel pipe and pipe
The zinc coat of part inwall has been destroyed, and carbon steel pipe and pipe fitting are etched oxidation, the use of fire protection pipeline under the effect of current
Life-span will have a greatly reduced quality！Too impatient to wait, need to improve.
Summary of the invention
In order to solve technological deficiency and the hidden danger that prior art exists, an object of the present invention is to provide a kind of metal
Pipe clasp type attachment structure, this metallic conduit snap ring-type attachment structure be applicable to fire fighting supply, combustion gas, heat, drink cold and hot
The metallic conduit snap ring-type attachment structures such as water, draining, air conditioner water, compressed air and penetration pipe, this metallic conduit snap ring-type connects
Structure can reduce installation cost and improves installation effectiveness and strengthen the safety and reliability that pipeline connects.
To achieve these goals, the technical scheme is that
A kind of metallic conduit snap ring-type attachment structure, including clasp pipe fitting, metal tube, it is characterised in that: at snap ring-type

Described metal tube is provided with annular pattern section, and annular pattern section is located at assembling sealing ring and the position of C-shaped snap ring,
The annular pattern section degree of depth is 0.1-1mm, and width is 3-20mm.
The two of the purpose of the present invention are to provide the preparation method of a kind of metallic conduit snap ring-type attachment structure, described gold
The preparation method of metal conduit snap ring-type attachment structure is: clasp pipe fitting is formed through operations such as flare formation welding by pipe
A bellmouth or multiple bellmouth, comprise arbitrary specification that the pipe-line systems such as straight-through, threeway, elbow are comprised, use exclusive clamps
Tool has only to the seal groove for pipe port and annular groove extrudes, and seal groove is extruded by fixture, forces cutting in groove
Face ellipse sealing ring is close to metal tube and is played the effect of hermetic seal, and annular groove is squeezed, and forces the metal clasp in groove tight
The annular pattern section of compact imbeding metal tube plays anti-pulling effect, and test data proves the tension that the snap ring-type of equivalent specifications connects
Pull out force is more than 2.2 times of cartridge connection tension pull out force.
Beneficial effects of the present invention, after using technique scheme, particularly outside cross section ellipse sealing ring (20)
Wall is provided with annular groove and C-shaped card is equipped with snap ring opening, connects effect notable, through more than 100 metals for all size
Pipe clasp type attachment structure carries out destructive testing connecting portion all without being damaged, and the phenomenon of absolutely not evaporating, emitting, dripping or leaking of liquid or gas occurs.
In sum, metallic conduit snap ring-type attachment structure technology is applied to the connection of metallic conduit, especially fire-fighting use
Thin-walled galvanized pipe pipeline, will turn over a new page with being connected for the construction of thin-walled fire-fighting galvanized pipe.It can not only save substantial amounts of
Steel, also make to eliminate the laborious threaded connection method of tradition and are possibly realized, and also terminated zinc-plated carbon steel pipe secondary installing simultaneously
History, for on-the-spot civilized construction, improves working environment, reduces labor intensity and create condition, snap ring-type interconnection technique and thin-walled
Zinc-plated carbon steel pipe forms series of products, then fire fighting supply, combustion gas, heat, to drink hot and cold water, draining, air conditioner water, compression empty
The market prospect of the application such as gas and penetration pipe is the most extensive.
