Description
Technical field
The present invention relates to a kind of stainless steel waterpipe mounting auxiliary, specifically a kind of small-diameter, thin-walled stainless steel tube sealing
Enclose gatherer.
Background technology
Domestic running water pipe, due to the deficiency in material and structure design, is allowed to easily be influenceed by external condition at present,
The phenomenons such as corrosion failure are produced, the service life of pipe is shortened.Meanwhile, the inwall of pipe gets rusty easily, the generation influence of scale
The quality of water, is unfavorable for the health of human body.In addition, not rolling resistance is also there is, be can not resist cold, not antidetonation, quality is big, peace
The factors such as dress maintenance inconvenience.Therefore as water supply line, zinc-plated pipeline has been eliminated, the various plastic tubes generally used now
Road and plastic-aluminum combined pipeline, but also due to intensity, poor rigidity, connection reliability difference etc., it is not preferable supply to be recognized as
Waterpipe.However, evaluating a kind of pipeline, it should consider in terms of two.One be will be from pipeline integrally i.e. in addition to tubing, will also be from
The conduit fittings such as pipe fitting and valve, water nozzle, water meter considers.Two be to consider from the performance and price of pipeline.Due to thin
The wall thickness of wall stainless steel tube only has 0.5-1.2mm, and its price is greatly lowered, and its performance and traditional stainless steel tube phase
Together, therefore by engineering circles favored.By taking 304 stainless steel tubes as an example, its tensile strength is 2 times of common steel tube, is copper pipe
3-4 times, 8-10 times of plastic tube.The intensity of material determines the whether firm crashworthiness of water pipe, safe and reliable.And safe and reliable be
It is most important in building water supply to require.In the case of by external force collision, the possibility of stainless steel water tube leakage is minimum, and
Copper pipe and plastic tube water leakage ratio are just higher, and pipeline is easily constructed or secondary decoration is damaged.Domestic several big main cities are occupied to modeling
Expect that the main cause that water pipe is complained is leak, a main cause of leak is that plastic water pipe cannot stand external force collision.
And in building water supply system, operating pressure is generally higher than 0.6Mpa；It is higher to tubing bearing requirements.Plastics
Manage and be respectively less than this value for water supply system operating pressure, it is impossible to be competent；Two kinds of material expand coefficient difference of multiple tube are big, such as viscous
Absciss layer is also easy to produce when conjunction is loosely or temperature change is big；Thin-wall copper pipe pressure-bearing is maximum up to 5.9Mpa；And thin-wall stainless steel due to
Excellent mechanical performance, can bear very high pressure of supply water, up to more than 10Mpa, be particularly suitable for building water supply.But at present
Thin wall stainless steel water supply pipeline, be still in the initial stage of development stage, have not yet been formed from tubing, pipe fitting until conduit fittings is complete
System.By taking water pipe adapter as an example, at present, in engineering construction, in the water pipe for different tube diameters of plugging into, the method for use is to use
Plant equipment stretches the larger one end of caliber, its extension caliber is diminished, is finally docked with the water pipe of pipe with small pipe diameter.Right
When connecing, because stainless steel tube wall is relatively thin, hardness is higher, it is impossible to connected using the mode of processing screw thread, so to use welding
Mode is connected.However, welding is a kind of connected mode for being welded tubing insertion bellmouth, although the advantage of this connection is just
It is that tension pull out force is maximum, inside is without sealing ring, but it belongs to fast knot, can only be useful in cold water, hot-water heating system.But
It requires too high to construction and welding scene protection, and inside and outside argon gas protection is relatively difficult to achieve at the construction field (site) sometimes, while being difficult to shut out
Inwall not heated discoloration, is that the corrosion in whole pipe-line system future leaves hidden danger during exhausted welding, therefore it is not so optimal
Connected mode.Therefore occurred in that it was the hexagonal mould by about one open-close type to top hexagonal cartridge connection mode again later
Tool is clamped on the two pipe fittings for needing to dock, and pipe fitting is squeezed into the crimping mouthful of hexagonal by matched moulds, to make the sealing between pipe fitting
Circle effectively shrinks, and plays sealing function.But existing stainless steel tube sealing ring is installed in pipeline in scrobicular ring, this is accomplished by
Before pipeline is to section, after first sealing ring is installed, docking pipeline is inserted into.Usual sealing ring is using manually installed, at some
In large-scale pipeline, finger can be directly protruding into pipeline and install by user, and any problem is not present in installation process.But for one
A little small-sized pipelines, usual user is difficult to finger being directly protruding into pipeline, while the diameter under sealing ring normality is more than the mouth of pipe
Opening size, accordingly, it would be desirable to will can be installed after sealing ring undergauge or distortion in pipeline, causes installation rate slow, production
The low drawback of efficiency, it is therefore necessary to be further improved to it.
