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

Technical field

It is convenient simple in accessory the present invention relates to fluid circulation system, more particularly to the sealing structure that push-in type coordinates Insertion and the apparatus and method for removing ductwork components.

Background technology

Pipe-line system facilitates the circulation of fluid (e.g., liquid, gas (such as air) or plasma).Such as family, school, doctor Institute, commercial building and other building generally require complete pipe-line system, so that water and/or other fluid streams are general In various uses.Liquid and/or gas, such as cold water and hot water, the air for breathing, ethylene glycol, compressed air, inert gas, Cleaning agent, waste water, factory's cooling water, paint and coating are the examples of some liquids and gases, can be adjusted by pipe-line system Degree.The type of pipe may include that such as copper pipe, stainless steel tube, CPVC (chliorinated polyvinyl chloride) pipes and PEX (crosslinked polyethylene) are managed. For purpose disclosed by the invention, term " pipe " or " tube elements " are interpreted as including one or more pipes and/or tube elements.

Pipe connection is required with the pipe for engaging different piece, and must be general, to be adapted to particular conduit system The change in the pipe direction required in implementation.Such as, accessory and valve can be used in the end of open tube, make two parts pipe with specific Layout is mounted together.In fitting type, for example, have elbow, T connector, suitable for various purposes, such as pipe sizing Connector, plug, ball valve, stop valve and the local curved formula joint of change.

Conventional tube elements typically by using welding torch welding and/or weld together.It is time-consuming, dangerous to weld accessory And be labour-intensive.Welding is also required to use various materials, such as copper pipe and accessory, emery-cloth or brush for channel cleaning, helps Solder flux, silver solder, welding torch and igniter, pipe cutting machine and goggles.Welded tube technique can be opened by preparing pipe to be welded first Begin, while to form good bond, copper surface must be cleaned.Tube end can use emery-cloth or special wire brush outside Clean in portion.It must also be cleaned inside accessory.Next, can prefluxing (a kind of pastel) to remove oxide, take slicken solder To its surface by the joint of connection.Brush can be used for scaling powder being applied to inside accessory and tube exterior.Followed by two pipes Son is by firmly pressed together and in place, so that they " are bottomed out ", i.e., in accessory internally flush.To avoid weldering, solder Top can be bent to the size of pipe.As pipe and accessory are in place, then light welding torch to open with igniter or automatic ignition mechanism Begin to weld.Heat after a few minutes, if copper surface is hot enough, so that solder melts when solder tails contact copper surface, then solder Available for joint close, spread on so as to solder around joint and pipe and accessory are connected as a single entity.

In recent years, push-in type technique has been used 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.Such as, in order to using push-in type technique Pipe is connected, pipe, quick coupling fittings, chamfer/debur tool and pipe cutting machine can be only needed.

The step of being related to using push-in type technique connecting pipe system can be summarized as follows.First, pipe cutting is into suitable Length simultaneously cleans tube end with deburring tool.Then pipe and accessory are slippaged and linked together.Accessory has dead ring (also referred to as collet chuck, snap ring or clasp), dead ring band tooth, when pipe is inserted into, the tooth of dead ring blocks pipe.Fasten loop device For providing reaction force, prevent the device from disconnecting when creating positive seal.Accordingly it is not required to spanner, clamp, bonding and Welding.Push-in type and/or quick Joining Technology such as pipe-line system can pass through U.S. Rhode Island Dong Puluoweidengsishi Fast assembling (Quick Fitting) companySerial push-in type accessory and Related product supplier obtain.In addition, This technique exists, and the U.S. of such as Patent No. 7,862,089,8,205915,8,210,576,8,398,122 and 8,480,134 is special Described in profit, their disclosure is incorporated as reference herein.

In conventional pipe Joining Technology, dead ring inserts fitment body along plastic clasp bearing, in substantial amounts of stretching Often failed in test.Further, connection must be rolling formula, bonding or receive nut member so that dead ring keep In fitment body.Except the manufacture for Joining Technology and the additional step of assembling, the intensity of pipe joint is by holding nut Element is determined.Additional step and part dramatically increase work and manufacturing cost to the cost of final products, and due to unique group Dress needs the time extended and reduces aggregated capacity.

Except recited above, when using screw thread retention cap method, screw thread is scribed in accessory theme and retention cap Process improves the cost of manufacture fitting component.Further, end of thread cap method not only needs mechanical package, and needs attached Addition sheet and to screw thread application thread sealant.In the conventional retention cap method using casting, casting fitting body is used as guarantor The technique for holding cap significantly increases being finally assembling to originally for accessory.In addition, dead ring is wrapped in accessory by casting technique always, Thus, in the case of not exclusively destruction ring and accessory, dead ring can not be removed.

Except additional number of assembling steps and increased manufacturing cost, due to a variety of causes, conventional accessory and connection method are not Allow maintenance.In some cases, e.g., this is due to that they are in factory seal.In other cases, because accessory and pipe The separation of son can be damaged or worn out part.Such as, some push-in types connection accessory being used for permanently fixation removes accessory Stripping ring.Stripping ring can be axially pressed so that the tooth of dead ring to be lifted away to the pipe surface of insertion, so that pipe can be drawn back into.So And, it is shorter that this structure makes accessory damage the simultaneously life-span.In addition, when fastening loop device effectively works as counteractive holding element When, their function makes their hardly possible dismountings, removes or take apart for recycling.So, dead ring is permanent Ground adheres to, unless they are cut and removed, this will destroy dead ring.

No matter connected by traditional welding method, or using the connection of push-in type method, always practical application needs more Part and valve are changed, and in the case where only internal widget needs repairing or changed, the repetition profit of accessory or valve is not allowed With.
