Abstract

The utility model relates to a welding-free stainless steel corrugated pipe sealing structure which comprises a stainless steel corrugated pipe, silicone rubber O-shaped rings, a stainless steel snap ring, a sealing flat gasket, a pipe base and a threaded pipe stopper. The silicone rubber O-shaped rings, the stainless steel snap ring, the sealing flat gasket and the threaded pipe stopper are sequentially assembled in the pipe base. The pipe opening of the stainless steel corrugated pipe is pressed into a plane, the silicone rubber O-shaped rings are assembled in wave troughs in the outer wall of the stainless steel corrugated pipe, the stainless steel snap ring is arranged in the first wave trough close to the pipe opening, and the threaded pipe stopper enables the sealing flat gasket and the end face of the stainless steel corrugated pipe to be compressed and sealed. The welding-free stainless steel corrugated pipe sealing structure has the advantages that processing cost is low, at least two silicone rubber O-shaped ring structures are used for achieving elastic sealing, the end face of the stainless steel corrugated pipe is sealed through the flat gasket, through the double-sealing structure, mutual independence can be achieved, influences can be avoided, temperature resistance, pressure resistance and sealing performance can all be greatly improved, the threaded pipe stopper can be hidden in the pipe base after being locked, later pipe connection cannot affect the existing sealing structure, and therefore safety and reliability are achieved.

Description

A kind of soldering-free type corrugated stainless steel tubing sealing configuration
Technical field
The utility model relates to a kind of sealing configuration of stainless bellows, is suitable for the heat exchange water tank of corrugated stainless steel tubing as heat exchanger, belongs to Application of Solar Energy field.
Technical background
At present, the application of heat-exchanging pressure-bearing solar water container is more and more extensive, corrugated stainless steel tubing is used for stainless steel water tank as heat exchanger, just progressively substitute stainless steel water tank copper pipe heat exchanger, because it is identical with stainless steel inner container material, solve the potential difference etching problem of unlike material, simultaneously thin, the good pressure-resistant performance of corrugated stainless steel tubing wall, heat exchange area are large, suitable with copper pipe heat exchanger with price aspect heat exchange, thus have more advantage.Adopt the maximum technological difficulties of corrugated stainless steel tubing heat exchange to be, the sealing problem of corrugated stainless steel tubing and stainless steel inner container.Have at present two kinds of solutions, one is welding process, because corrugated stainless steel tubing wall is thin, welding procedure control ratio is more difficult, easily weld the easy corrosion in leakage and heat affected zone etc., and another kind of scheme is to exempt to weld watertight construction, described in patent Zl201020156219.8.Although solution sealing problem, but cost is higher and in the time of water tank practical set water pipeline, easily cause screw bolt loosening and make the seal failure of polytetrafluoro plain cushion, silica gel sealing ring will adopt compressing method ability effectively and nut seal, two sealing positions interdepend, once therefore screw bolt loosening still can cause sealed type bad.
Summary of the invention
The utility model has done significant improvement to the structure in patent Zl201020156219.8, has reduced the impact that processing cost and sealing configuration are not installed by later stage pipeline, more safe and reliable.
In order to address the above problem, the sealing configuration of a kind of soldering-free type corrugated stainless steel tubing of the utility model comprises corrugated stainless steel tubing, silicone rubber O type circle, Stainless Steel Retainer Ring, sealing plain cushion, base and screw thread pipe close, in described base, assemble successively silicone rubber O type circle, Stainless Steel Retainer Ring, sealing plain cushion and screw thread pipe close, the described corrugated stainless steel tubing mouth of pipe is pressed into plane, described silicone rubber O type circle is assemblied in the trough of stainless outer wall, described Stainless Steel Retainer Ring is assemblied in first trough that closes on the mouth of pipe, described screw thread pipe close will seal plain cushion and corrugated stainless steel tubing end face press seal.
Above-mentioned a kind of soldering-free type corrugated stainless steel tubing sealing configuration, has a step in described base, for holding Stainless Steel Retainer Ring, the end face bellows that blocks corrugated stainless steel tubing can not slide.
Above-mentioned a kind of soldering-free type corrugated stainless steel tubing sealing configuration, the end face of described corrugated stainless steel tubing at least flattens 2 crests, is that end face forms level and smooth face.
Above-mentioned a kind of soldering-free type corrugated stainless steel tubing sealing configuration, described silicone rubber O type circle, at least assembles 2, can be assemblied in trough in the trough that corrugated stainless steel tubing is adjacent or separately.
Above-mentioned a kind of soldering-free type corrugated stainless steel tubing sealing configuration, described screw thread pipe close is hidden in base inside, and has certain distance apart from the mouth of pipe of described base.
Structure of the present utility model is compared with the structure in Zl201020156219.8, advantage is that processing cost is low, adopt at least 2 silicone rubber O type coil structures elastic packings, corrugated stainless steel tubing end face adopts plain cushion sealing, double sealing structure is independent unaffected each other, heatproof, withstand voltage and all raisings greatly of sealability, and screw thread pipe close locking Tsang is in base, the pipe fitting in later stage connects can not have influence on existing sealing configuration, safe and reliable.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model soldering-free type stainless steel sealing configuration.
Embodiment
As shown in Figure 1, the structure of the utility model soldering-free type stainless steel sealing configuration comprises corrugated stainless steel tubing 1, silicone rubber O type circle 2, base 3, Stainless Steel Retainer Ring 4, sealing plain cushion 5, screw thread pipe close 6.Described silicone rubber O type circle 2 is assemblied in the trough of corrugated stainless steel tubing 1, work the inside that is placed in base 3, at least 2 silicone rubber O type circles 2 contact compressive strain and form elastic packing with the inside of base 3 with corrugated stainless steel tubing 1 outer wall, the end of corrugated stainless steel tubing 1 at least flattens 2 crests and forms smooth end face, Stainless Steel Retainer Ring 4 is placed in first trough of end of corrugated stainless steel tubing 1 and is stuck in base 3 interior step places, sealing plain cushion 5 is placed in corrugated stainless steel tubing 1 end, refills and joins screw thread pipe close 6 and the interior press seal plain cushion 5 formation sealings of base 3.Thereby form the inside and outside dual sealing of corrugated stainless steel tubing 1.
