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 structure that push-in type coordinates, convenient equipment and the method simply inserting and removing ductwork components in accessory.

Background technology

Tubing facilitates the circulation of fluid (e.g., liquid, gas (such as air) or plasma).As family, school, hospital, commercial building and other building it is generally required to complete tubing, in order to water and/or the circulation of other fluids are for various uses.Liquid and/or gas, such as cold water and hot water, cooled down, for the air of breathing, ethylene glycol, compression air, noble gas, cleaning agent, waste water, factory, the example that water, paint and coating are some liquids and gases, can be scheduling by tubing.The type of pipe can include, such as copper pipe, stainless steel tube, CPVC (chliorinated polyvinyl chloride) pipe and PEX (crosslinked polyethylene) pipe.For purpose disclosed by the invention, term " pipe " or " tube elements " are interpreted as including 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, the change in the pipe direction required in implementing with applicable particular conduit system.As, accessory and valve can be used on the end of opening pipe, make two parts pipe be mounted together with specified arrangement.In fitting type, for example, have elbow, T connector, suitable in various purposes, such as the adapter of pipe sizing change, plug, ball valve, the curved formula joint of stop valve and local.

Conventional tube elements is typically via using welding torch welding and/or welding together.Welding accessory is time-consuming, unsafe and is labour-intensive.Welding is also required to use various material, such as copper pipe and accessory, emery-cloth or brush for channel cleaning, scaling powder, silver solder, welding torch and lighter, pipe cutting machine and protective eye lens.Welded tube technique can be passed through first to prepare pipe to be welded and start, and simultaneously for forming good bond, copper surface must be cleaned.Tube end can with emery-cloth or special wire brush in exterior clean.Also must clean inside accessory.It follows that to remove oxide, the joint that slicken solder will connect to its surface can be taken by prefluxing (a kind of pastel).Brush can be used for scaling powder is applied to accessory inside and tube exterior.Followed by, two tubes is by firmly pressed together and in place, in order to they " bottom out ", 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 lighter or automatic ignition mechanism.After heating a few minutes, if copper surface is enough hot, so that solder melts during solder tails contact copper surface, then solder can be used for joint close, in order to solder spreads on around joint and pipe and accessory is connected as a single entity.

In recent years, push-in type technique has been used for tubing, 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 to connect pipe, can only need pipe, quick coupling fittings, chamfer/debur tool and pipe cutting machine.

The step that push-in type technique connection tubing relates to is adopted to be summarized as follows.First, pipe cutting becomes suitable length and cleans tube end with deburring tool.Then pipe and accessory are slippaged and are linked together.Accessory has dead ring (also referred to as collet chuck, snap ring or clasp), fastens endless belt tooth, and when pipe is inserted into, the tooth of dead ring blocks pipe.Dead ring device is used for providing counteracting force, prevents this device from disconnecting when creating positive seal.Accordingly it is not required to spanner, clamp, bonding and welding.As can be passed through fast assembling (QuickFitting) company of U.S. Rhode Island Dong Puluoweidengsishi for the push-in type of tubing and/or quick Joining TechnologySeries push-in type accessory and Related product supplier obtain.It addition, this technique exists, if the patent No. is 7,862,089,8,205915,8,210,576,8,398,122 and 8, described in the United States Patent (USP) of 480,134, the open of them is incorporated with for referencial use herein.

In conventional pipe Joining Technology, dead ring inserts fitment body along plastic clasp bearing, often loses efficacy in substantial amounts of extension test.Further, connect must be rolling formula, bonding or receive nut member so that dead ring is maintained in fitment body.Except the additional step for the manufacture of Joining Technology and assembling, the intensity of pipe joint determines by keeping nut member.Additional step and parts dramatically increase work and the manufacturing cost cost to final products, and owing to unique assembles the time needing to extend and reduce aggregated capacity.

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 to screw thread application thread sealant.In the maintenance cap method in the past using casting, casting fitting body significantly increases being finally assembling to originally of accessory as the technique keeping cap.Additionally, dead ring is wrapped in accessory by casting technique always, thus, not exclusively destroying in ring and accessory situation, dead ring can not be removed.

Except the manufacturing cost of additional number of assembling steps and increase, due to a variety of causes, conventional accessory and method of attachment do not allow maintenance.In some cases, e.g., this due to they be at factory seal.In other cases, because accessory can be damaged or worn out parts with separating of pipe.As, some push-in types connect accessory and have the permanent fixing stripping ring for removing accessory.Stripping ring can be axially pressed the tooth of dead ring is lifted away from the tube-surface of insertion, in order to pipe can be drawn back into.But, this structure makes accessory damage and the life-span is shorter.Additionally, when dead ring device effectively works as counteractive holding element, their function makes they hardly possible dismountings, removes or take apart for recycling.So, dead ring is permanently adhered to, unless they cut and removals, this will destroy dead ring.

Connecting whether by traditional welding method, or adopt push-in type method to connect, practical application always needs to change accessory and valve, and when only internal widget needs repairing or changes, does not allow the recycling of accessory or valve.
