The circular hole of 1.5~2.5mm, and it is located at the multiple circular holes of the online multiple circular holes of first tempering and second tempering on the net
It is opened up by the way of being dislocatedly distributed.
Further, the spacing distance between the first tempering net and the second tempering net is 70~80mm.
Further, the tempering inside pipe wall is equipped with annular convex platform, makes the first tempering net and second tempering
Net is press-fitted to respectively at the upper surface and lower end surface of the annular convex platform；The method of the upper connecting flange and the lower connecting flange
Blue pipe is inserted into the tempering tube and is fixed on the inner wall of the tempering tube and its tube body end face is against described first respectively
It is tempered net and second tempering is online.
Wherein, the fixed form between the upper connecting flange and the lower connecting flange and affiliated tempering tube can use
But it is not limited to be threadedly coupled fixed or be welded and fixed；Consolidating between the first tempering net and the second tempering net and tempering tube
Determining mode can use but be not limited to be welded and fixed.
The natural gas open flow burning line fireproof tempering device is mounted on the torch lower end of natural gas open flow burning line, plays
When gaseous-pressure reduces in pipe, tempering tube interior air-flow is avoided to change disorder using the first tempering net and the second tempering net,
Flame retraction is blocked, the fire for effectively preventing natural gas to burn in open flow combustion process a little is climing to gas source direction by pipeline
Prolong, the purpose of safety accidents such as causes to fire.

Specific embodiment
With reference to the accompanying drawing and specific embodiment is described further the utility model, but following embodiments are right absolutely not
The utility model has any restrictions.
As shown in Figure 1, the natural gas open flow burning line fireproof tempering device include upper connecting flange 1, first be tempered net 2,
Second tempering net 3, lower connecting flange 4 and tempering tube 5；Wherein,
Tempering tube 5 be a root long degree be 150mm steel pipe, internal diameter 65mm, outer diameter 73mm, with oil/gas well production in
Common 2-7/8 " oil pipe is identical；The annular that an axial length is 75mm is convexed to form in the middle part of the inner wall of tempering tube 5 outward
Boss, the annular convex platform keep the first tempering net 2 and the second tempering net 3 flat for the first tempering net 2 and the second tempering net 3 to be arranged
Row setting and spacing distance between the two are 75mm；
As shown in Figures 2 and 3, the first tempering net 2 and the second tempering net 3 are two stainless (steel) wires for offering multiple circular holes
Body；Specifically, the first tempering net 2 and the upper of the second tempering net 3 offer the circular hole that 25 internal diameters are 2mm respectively, can both protect
Gas flows through in card open flow burning line 9, can also lead to impurity heap to avoid because there is solid impurity in the gas to be burnt
In product blocking anti-backfire pipe 5；The circular hole on the first tempering net 2 and the second tempering net 3 is additionally disposed in by the way of being dislocatedly distributed
