Description
Technical field
The present invention relates to tubing interconnection technique field, more particularly, between a kind of foreign peoples's pipe sealing locking structure and its
Seal locking method.
Background technology
Heat exchanger be it is a kind of between two or more fluid of different temperatures realize material between heat transfer section
Energy equipment, is that heat is made to pass to the lower fluid of temperature by the higher fluid of temperature, fluid temperature (F.T.) is made to reach flow specification
Index to meet the needs of process conditions, while being also one of the capital equipment for improving energy utilization rate.Heat exchanger industry is related to
HVAC, pressure vessel, sewerage disposing equipment, chemical industry, nearly 30 multi industries such as oil mutually form industry chain (supply chain).Data are shown
Chinese heat exchanger industrial market scale in 2010 at 50,000,000,000 yuan or so, focus primarily upon oil, chemical industry, metallurgy, electric power, ship,
The fields such as central heating, refrigeration air-conditioner, machinery, food, pharmacy.The material for wherein being used to make heat exchanger mainly has copper, stainless
Steel, titanium and its alloy are made, and copper and stainless steel are although most widely used, but seawater corrosion resistance ability is poor, therefore in naval
The fields such as battleship, ship and Binhai Generator Station service life is short, and spirit keeps coefficient relatively low, although and titanium completely not by seawater corrosion,
But titanium is expensive, therefore in practical applications, and people will use Titanium system with the heat exchanger tube of contact with sea water, and will not be with
The heat exchanger tube of contact with sea water makes to be made of copper, and not only can resist the corrosion of seawater, can also reduce use cost,
So in actual use, it is necessary to copper pipe and titanium tube are attached, and since copper pipe and titanium tube belong to material of different nature
The fusing point of matter, copper is 1000 DEG C or so, and the fusing point of titanium is 1600 DEG C or so, since the fusing point of the material of the two differs too big, nothing
Method is connected and sealed by welding, for metal material industry, even the tubing of unlike material welds reluctantly
It connects, intensity is also relatively poor, therefore during current use, and the connection of copper pipe and titanium tube is by using one
Copper threaded connector fitted seal circle connects, and the market price of a copper threaded connector is at 15 yuan or so, but also
Screw thread is processed on copper pipe and the outer wall of titanium tube, it is higher to allow for manufacturing cost in this way.
