Description
Technical field
The present invention relates to fluid flow system, the push fit formula pipe coupling assembly, the system and method that particularly improve, the method is convenient to repairing and the use of pipe-line system parts, without the need to using mold pressing or thread ending cover.
Background technique
Pipe-line system is used for facilitating the flowing (such as, liquid, gas (such as air) or plasma) of fluid.Such as, the structure of family, school, medical facilities, commercial building and other inhabitation people all needs integrated pipeline system usually, like this, water and/or other fluid capable of circulation, to make multiple use.Liquid and/or gas, the air of such as cold water and hot water, breathing, ethylene glycol, pressurized air, inert gas, cleaning chemical, waste water, factory's cooling water, paint and coating, some examples of these fluids just carried by pipe-line system and other kind.Such as, tubes/conduits road kind can comprise copper, stainless steel, CPVC (chlorinated polynvinyl chloride (CPVC)) and PEX (crosslinked polyethylene).In the present invention, term " pipe " or " pipeline " can be regarded as and comprise one or more pipe, pipeline, pipeline parts and/or piping element.
Pipeline connecting parts is necessary for the connection of pipe various piece, and must be multiduty, in order that the change in pipeline direction required when being adapted at specific pipeline System Implementation.Such as, in the end of pipe open section, accessory and valve can be used, to make pipe two-part can be assembled together in specific arrangements.In various accessory, there are elbow, "T"-shaped joint, the joiner that applicable multiple use such as pipe sizing changes, end, ball valve, stop valve, and the link in Partial angle.
In the past, the connection of tube element is all use welding gun to be welded and/or be brazed together usually.The welding of pipe fitting is quite time-consuming, dangerous, and labor intensity is large.In addition, welding also requires to use many materials, such as copper pipe and accessory, emery cloth or tubes clean brush, solder flux, silver solder, welding gun and burning torch (striker), pipe cutter and safety goggles.The technique of pipeline welding is the pipe first preparing to need welding, because copper surface must be cleaned, to form good connection.Tube end outer surface can clean with emery cloth or special steel wire brush.The inside of accessory also must be cleaned.Then, solder flux (a kind of paste) is with removing oxide and the solder of thawing being dissolved into the surperficial seam crossing connected.With brush, solder flux is coated to the outside of accessory inside and pipe.Then, two tubes can be advancing to the position firmly, to make it " touch the end (bottomout) "---namely, and two tubes alignment in accessory.The top of solder then bends to the size of pipe, avoids excessive welding.After pipe and accessory are seated, then light welding gun with burning torch or automatic ignition mechanism, start welding.After the heating that have passed through a few minutes, if copper surface is enough hot, can melt when electrode tip is contacted, then, apply solder, to make it around seaming operation thus to make pipe and accessory combine at seam crossing.
In recent years, pipe-line system uses push fit technology, the danger brought when decreasing weld and time loss.Push fit method is without the need to extremely understanding pipe fitting, and compared with welding, material therefor is much less then.Such as, when using push fit technology to be linked together by pipe, people only can need pipe, quick coupling fittings, chamfering/flash removed instrument and pipeline cutter.
Use the step summary adopted during push fit technology connecting pipeline system as follows.First, pipe cutting is become suitable length, tube end flash removed instrument cleans.Then, pipe and accessory are pushed together connection.Accessory has retaining ring (being also referred to as chuck, snap ring or dog collar), retaining ring has the tooth clamping pipe when pipe inserts.Retaining ring device is used to provide backward energy, and disconnecting appears when forming reliable sealing in anti-locking apparatus.For this reason, without spanner, clamping, gummed or welding.Such as, by the fast assembling company (Quick Fitting, Inc.) of Rhode Island,USA Dong Puluoweidengsi, can obtain the push fit of pipe-line system and/or quick interconnection technique, the said firm is
the supplier of series pipe fitting and Related product.In addition, such as, the U.S. the 7th, 862, No. 089 patent describes this technology, and whole disclosures of this patent are incorporated herein by reference.
In pipe joint technology in the past, retaining ring is inserted in accessory body together with plastic clasp support, and snap ring support can damage when strict tensile test usually.In addition, pipe coupling then must be carried out mold pressing (coin rolled), gummed or accept thread ending cover component to keep retaining ring in accessory body.Except the manufacture of pipe coupling and the additional step of assembling, also need the intensity by keeping cover member to measure pipe coupling (plumbing joint).Additional step and parts considerably increase labour force and the manufacture cost of final products cost, because proper mating needs the plenty of time, thus reduce overall throughput.
In addition to the foregoing, when using screw thread to keep end cap method, the technique that accessory body and maintenance end cap cut screw thread too increases the cost of processing fitting component.In addition, thread ending cover method requires adopt Automatic manual transmission and use thread sealant on screw thread, thus adds cost.Keep, in the existing way of end cap method, accessory body being molded into the final assembly cost keeping the technique of end cap to considerably increase accessory in application mold pressing.In addition, retaining ring can be for good and all encapsulated in accessory inside by mould pressing process, and like this, retaining ring just can not be removed, unless thoroughly destroyed retaining ring and accessory.
Except increasing installation step and fabricating cost, for a variety of reasons, the pipe fitting in past and connecting means do not allow to place under repair.Such as, in some cases, this is because they are at factory seal.In other cases, this is because a point defection for accessory and pipe damages parts or causes component wear.Such as, in order to remove accessory, some push fit pipe fittings have the stripping ring be permanently fixed.Stripping ring can axially be depressed, and makes the tooth of retaining ring depart from the surface of the pipe inserted, then, pipe can be extracted out.But this layout can make pipe fitting occur play (tampering), reduction of service life.In addition, although retaining ring device is very effective as reverse fixed component, its function makes it may be removed, unload or take apart hardly to reuse.For this reason, retaining ring can for good and all be fixed in the above, unless by its cutting disassembling, but this can damage retaining ring.
No matter be adopt traditional welding method or use push fit method to connect, the way in past is all be used for specially connecting same material, and can not connect two kinds of different materials, such as copper and CPVC, PEX or stainless steel, or other combining form any of different materials.In addition, always the method in past also needs to change accessory and valve, although be when needing just inner widget needed for repair and replacement, do not allow to reuse accessory or valve yet.
