The traditional stainless steel corrugated pipe joint is complex in installation process, and water leakage or electric leakage is easy to occur once deviation occurs; if the water heater is in a working state before being disassembled, the metal threaded connector can be directly touched and disassembled to cause the hidden danger of scalding due to the fact that hot water in the pipe is rolled and scalded; furthermore, if the outlet pipe has leaked electricity before disassembly, electrical shock is also caused by touching the metal nut at the time of starting disassembly.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to foretell not enough, provide a simple to operate, effectively prevent owing to dismantle or change the insulating stainless steel corrugated pipe joint of scald and electric shock that stainless steel corrugated pipe joint arouses.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an insulating stainless steel corrugated pipe connects, includes interior nipple, go-between, pyrocondensation pipe and the insulating tube of coaxial setting, interior nipple and pyrocondensation pipe fixed cover respectively are established go-between inner wall and outer wall, the cover is equipped with insulating tube on the pyrocondensation pipe outer wall, interior nipple with the pipe length of pyrocondensation pipe all is greater than the ring length of go-between, the go-between is located the body central line department of pyrocondensation pipe and interior nipple.
Furthermore, the front end surface and the rear end surface of the inner connecting pipe are provided with flowing inclined planes facing the axis of the inner connecting pipe.
Further, the outer surface of the insulating sleeve is provided with installation grains.
Further, the insulating sleeve is made of foam.
Further, the heat shrinkable tube is a double-wall heat shrinkable tube containing glue.
The utility model has the advantages that:
in practical application, the stainless steel corrugated pipe to be connected is inserted into two ends of the connecting ring from two ends of the insulating sleeve, and the heat-shrinkable tube is baked at a temperature of more than one hundred twenty degrees, so that the heat-shrinkable tube is completely attached to the outer wall of the stainless steel corrugated pipe; the utility model discloses the installation is swift convenient, makes pyrocondensation pipe shrink simple to operate through toasting the pyrocondensation pipe, prevents to scald and electrocute through peripheral hardware insulation support.

Detailed Description
As shown in fig. 1, fig. 2 and fig. 3, an insulated stainless steel corrugated pipe joint includes an inner connecting pipe 1, a connecting ring 2, a heat shrinkable pipe 3 and an insulating sleeve 4, which are coaxially disposed, the inner connecting pipe 1 and the heat shrinkable pipe 3 are respectively fixedly sleeved on an inner wall and an outer wall of the connecting ring 2, the insulating sleeve 4 is sleeved on the outer wall of the heat shrinkable pipe 3, the pipe lengths of the inner connecting pipe 1 and the heat shrinkable pipe 3 are both greater than the ring length of the connecting ring 2, and the connecting ring 2 is located at the pipe body center line of the heat shrinkable pipe 3 and the inner connecting pipe 1.
In practical application, the stainless steel corrugated pipe 5 to be connected is inserted into two ends of the connecting ring 2 from two ends of the insulating sleeve 4, and the heat shrinkable pipe 3 is baked at a temperature of more than one hundred twenty degrees, so that the heat shrinkable pipe 3 is completely attached to the outer wall of the stainless steel corrugated pipe 5; the utility model discloses the installation is swift convenient, makes 3 shrink simple to operate of pyrocondensation pipe through toasting pyrocondensation pipe 3, prevents to scald and electrocute through peripheral hardware insulation support 4.
As shown in fig. 1 and 2, flow slopes 11 facing the axis of the inner joint pipe 1 are provided on both front and rear end surfaces of the inner joint pipe 1; in this embodiment, when hot water flows through the inner wall of the inner joint pipe 1, the flow slope 11 reduces the friction force of the pipe wall of the inner joint pipe 1 on the hot water, and effectively prevents the hot water from leaking between the inner joint pipe 1 and the connection ring 2, which causes the scald due to the water leakage of the joint of the stainless steel corrugated pipe 5.
As shown in fig. 1 and 2, the outer surface of the insulating sleeve 4 is provided with a mounting line 41; in this embodiment, the friction force when taking the stainless steel corrugated pipe 5 joint installation is increased through the installation lines 41, so that the installation is more convenient and faster.
As shown in fig. 1 and 2, the insulating sleeve 4 is made of foam; in this embodiment, the foam can effectively insulate against heat, effectively prevents to install or dismantle 5 joints of in-process touching nonrust corrugated steel pipe from causing the scald.
As shown in fig. 1 and fig. 2, the heat shrinkable tube 3 is a double-wall heat shrinkable tube containing glue; in the embodiment, the outer layer of the double-wall heat-shrinkable tube containing glue is made of high-quality polyolefin alloy and the inner layer of hot melt glue through composite processing. The product is formed by irradiation crosslinking and continuous expansion of an electron accelerator after being formed. The outer layer has the advantages of softness, low-temperature shrinkage, insulation, corrosion resistance, wear resistance and the like, and the inner layer has the advantages of low melting point, good adhesion, waterproof sealing, mechanical strain buffering performance and the like. The wide application is waterproof, leak protection gas, anticreep in the wiring between electronic equipment and pipe fitting, the utility model discloses a contain gluey double-walled pyrocondensation pipe and effectively prevent installation or dismantle 5 joints of in-process touching nonrust corrugated steel pipe and arouse the electric shock.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein will be apparent to those skilled in the art without departing from the scope and spirit of the invention as defined in the accompanying claims.
