Abstract
An extrusion hard seal quick connecting pipe relates to the seal connection technology of two metal round pipes, wherein one end of a first round pipe is arranged in a second round pipe, an outer screw thread is arranged outside the second round pipe which is opposite to the first round pipe, an inner screw thread locking nut is arranged outside the first round pipe, the locking nut is connected with the second round pipe through screw threads, a copper or a stainless steel ring is sleeved outside the first round pipe in an interference way, and the inner diameter of the second round pipe is smaller than the outer diameter of the copper or the stainless steel seal ring. The extrusion hard seal quick connecting pipe can effectively improve seal span, and reaches the thermal-insulating and anti-corrosion purposes, and the hard seal has the characteristics of aging resistance, long service span, high temperature resistance, high pressure resistance, corrosion resistance, no leakage, high intensity, full through path, no blocking, no welding, no threading and fast connection, and a pipeline which is moveably connected is extremely convenient to mount, disassemble, modify and maintain.
Description
Technical field
The utility model relates to the technology that is tightly connected of two pipes, particularly two metal circular tubes.
Background technique
In engineering is used, when transmission pipeline is formed in two sections or above pipe phase continued access, need be connected and sealed between the adjacent pipe, existing Placement has clamp-press type, card convex type, compression type, rolls dentition formula, welding type and pipe dentition formula.Clamp-press type, card convex type and compression type all exist soft seal, easily aging, the life-span is short, the defective of non-refractory; Roll dentition formula and then have the defective of poor sealing performance, insufficient strength; Welding type exists construction inconvenient, and workpiece processing is coarse, the poor chromaking in weld joint, not corrosion resistant defective; Pipe dentition formula thickness of pipe wall then, cost height, work efficiency are low.
The model utility content
The utility model purpose be to provide a kind of make things convenient for installation and processing, anti-aging, the life-span long, high temperature resistant, corrosion resistant extrusion type hard-sealing fast-connection pipeline.
The utility model comprises first pipe and second pipe, one end of described first pipe is arranged in second pipe, outside second pipe of relative first pipe, outside thread is set, outside described first pipe, the internal thread locking nut is set, described locking nut is threaded with second pipe, it is characterized in that the outer interference of described first pipe is nested with copper or stainless steel coil, the internal diameter of described second pipe is less than the external diameter of described copper or stainless steel seal ring.
Owing to adopt copper or stainless steel seal ring to substitute traditional rubber seal, can effectively improve sealing life, reach high temperature resistant, corrosion resistant purpose.Because copper or stainless steel seal ring have certain extensibility, so, be threaded along with between locking nut and second pipe, the two ends tapering external diameter of copper or stainless steel seal ring is squeezed the back internal diameter to internal beam, produce two ends reach simultaneously in the more intact sealing of external diameter.Therefore, that this hard sealing of the present utility model has is anti-aging, the life-span long, high temperature resistant, high pressure resistant, corrosion-resistant, no leakage, high strength, all-pass footpath, no choked flow, do not have welding, no mantle fiber, connect fast characteristics, the pipeline installation, demolition, repacking, the maintenance that utilize the formula of living to connect are all very convenient.Be applicable to the pipeline inside nominal diameter less than DN50, Applicable media: cold water, hot water, air, steam, oil.The Applicable temperature scope is wide, and-196～+ 400 ℃ all can be used, and suitable nominal pressure can reach≤2.5MPa.
For convenient connection, improve sealing effect, the two ends of copper described in the utility model or stainless steel seal ring are tapered respectively; It is the same to lock the two chamfer taperings that are squeezed on the seal ring with it.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model mainly is made up of first pipe 1, second pipe 2, copper or stainless steel seal ring 3, locking nut 4.
The two ends of copper or stainless steel seal ring 3 are tapered respectively, are nested with outside first pipe 1 to copper or 3 interference of stainless steel seal ring.
One end of first pipe 1 is arranged in second pipe 2, outside second pipe 2 of relative first pipe 1, outside thread 2-1 is set, the internal diameter of second pipe 2 is less than the external diameter of copper or stainless steel seal ring 3, outside first pipe 1 internal thread locking nut 4 is set, locking nut 4 is threaded with second pipe 2.
Claims (2)
1. extrusion type hard-sealing fast-connection pipeline, comprise first pipe and second pipe, one end of described first pipe is arranged in second pipe, outside second pipe of relative first pipe, outside thread is set, outside described first pipe, the internal thread locking nut is set, described locking nut is threaded with second pipe, it is characterized in that the outer interference of described first pipe is nested with copper or stainless steel seal ring, and the internal diameter of described second pipe is less than the external diameter of described copper or stainless steel seal ring.
2. according to the described extrusion type hard-sealing fast-connection pipeline of claim 1, it is characterized in that the two ends of described copper or stainless steel seal ring are tapered respectively, the two chamfer taperings that are squeezed on the seal ring of locking are the same with it.
