Description

Push-in type connects and coordinates integrated seal structure, apparatus and method

Technical field

The present invention relates to fluid circulation system, particularly relate to the sealing configuration that push-in type coordinates, convenient equipment and the method simply inserting and remove ductwork components in accessory.

Background technique

Pipe-line system facilitates the circulation of fluid (e.g., liquid, gas (as air) or plasma).As family, school, hospital, commercial building and other building need complete pipe-line system so as water and/or other fluids circulation be used for various uses.Liquid and/or gas, if cold water and hot water, air, ethylene glycol, pressurized air, inert gas, detergent, waste water, factory's cooling water, paint and coating for breathing are the examples of some liquids and gases, dispatch by pipe-line system.The type of pipe can comprise, as copper pipe, Stainless Steel Tube, CPVC (chlorinated polynvinyl chloride (CPVC)) pipe and PEX (crosslinked polyethylene) pipe.For object disclosed by the invention, term " pipe " or " tube elements " are interpreted as and comprise one or more pipe and/or tube elements.

It is required that pipe connects to engage the pipe of different piece, and must be general, with the change in the pipe direction required in applicable particular conduit System Implementation.As, accessory and valve can be used on the end of opening pipe, and two-part pipe is installed to together with specified arrangement.In fitting type, for example, there are elbow, T connector, are applicable to various object, as connector, plug, ball valve, the curved formula joint of stop valve and local of pipe sizing change.

Tube elements was generally by using welding torch welding and/or welding together in the past.Welding accessory is time-consuming, unsafe and is labour-intensive.Welding also needs to use various material, as copper pipe and accessory, emery-cloth or brush for channel cleaning, soldering flux, silver solder, welding torch and igniter, pipe cutting machine and goggles.Welded tube technique starts by first preparing pipe to be welded, and simultaneously for forming good bond, copper surface must be cleaned.Tube end can with emery-cloth or special wire brush in exterior clean.Accessory inside also must be cleaned.Next, can prefluxing (a kind of paste) to remove oxide, get tin solder to its surface will connect junction point.Brush can be used for soldering flux being applied to accessory inside and tube exterior.Again then, two tubes is by firmly pressed together and in place, so that they " touch the end ", namely at accessory internally flush.For avoiding weldering, the top of solder can be bent to the size of pipe.Along with pipe and fitment in position, then light welding torch to start welding with igniter or automatic ignition mechanism.After heating a few minutes, if copper surface is enough hot, so that during solder tails contact copper surface, solder melts, then solder can be used for joint close, so that solder to spread on around junction point and pipe and accessory is connected as a single entity.

In recent years, push-in type technique for pipe-line system, to reduce risk and the time of welding connecting mode.Push-in type method requires minimum accessory knowledge compared to welding manner and needs the material of much less.As, in order to adopt push-in type technique connecting pipe, pipe, quick coupling fittings, chamfering/deburring tool and pipe cutting machine only can be needed.

The step adopting push-in type technique connecting tube system to relate to can be summarized as follows.First, pipe cutting becomes suitable length and uses deburring tool cleaning tubes end.Then pipe and accessory are slippaged and are linked together.Accessory has retaining ring (also claiming collet chuck, snap ring or clasp), fastening endless belt tooth, and when pipe is inserted into, the tooth of retaining ring blocks pipe.Retaining ring device is used for providing reaction force, prevents this device from disconnecting when creating positive seal.Correspondingly, spanner, clamp, bonding and welding is not needed.As for pipe-line system push-in type and/or fast Joining Technology by fast assembling (QuickFitting) company of U.S. Rhode Island Dong Puluoweidengsishi series push-in type accessory and Related product supplier obtain.In addition, this technique exists, if the patent No. is 7,862, and 089,8,205915,8,210,576,8,398,122 and 8, describe in the U. S. Patent of 480,134, the open of them is introduced with for referencial use by entirety herein.

In pipe Joining Technology in the past, retaining ring inserts fitment body along plastic clasp bearing, often loses efficacy in a large amount of extension tests.Further, connect must be rolling formula, bonding or receive nut member remain in fitment body to make retaining ring.Except for the manufacture of Joining Technology and the additional step of assembling, the intensity of pipe coupling determines by keeping nut member.Additional step and parts significantly increase work and manufacture cost to the cost of final products, and reduce aggregated capacity because the assembling of uniqueness needs the time of prolongation.

Except recited above, when adopting screw thread to keep cap method, the operation scribing screw thread in accessory theme and maintenance cap improves the cost manufacturing fitting component.Further, screw thread end cap method not only needs mechanical package, and needs fringe cost and double thread application thread sealant.In the maintenance cap method in the past using casting, casting fitting body is as the final assembly cost keeping the technique of cap to significantly increase accessory.In addition, retaining ring is wrapped in accessory by casting technique always, and thus, under not exclusively destroying ring and accessory situation, retaining ring can not be removed.

Except the manufacture cost of additional number of assembling steps and increase, due to a variety of causes, accessory in the past and connecting means do not allow maintenance.In some cases, e.g., this due to they be at factory seal.In other cases, because accessory can damage or wearout parts with being separated of pipe.As, some push-in type connection fittings have the permanent fixing stripping ring for removing accessory.Stripping ring can by the tube-surface axially pressed the tooth of retaining ring to be lifted away from insertion, so that pipe can be drawn back.But, this structure make accessory damage and the life-span shorter.In addition, when retaining ring device effectively works as counteractive holding member, their function makes them may dismantle, remove or take apart hardly for recycling.Like this, retaining ring is permanently adhered to, unless their cut and removals, this will destroy retaining ring.

No matter connected by traditional welding method, or adopt push-in type method to connect, always practical application needs to change accessory and valve, and when only inner widget needs repairing or changes, do not allow the recycling of accessory or valve.
