Technological scheme of the present invention is: a kind of combustion gas is with going out silk crossover sub within the walls by buried corrugated stainless steel tubing, comprise the crossover sub body of L shape, described crossover sub body comprises connecting tube and bending tube connected vertically with connecting tube, connecting tube communicates with bending tube, described bending tube by cross section be semi-circular shape supporting part and cross section be that the covering part of semi-circular shape combines; Supporting part wherein one end is fixedly connected with wherein one end of connecting tube, and covering part and supporting part removably connect; The free end sidewall of connecting tube is provided with positioning boss, and the free end inwall opening of connecting tube is provided with nested, and nested inwall is provided with screw thread.
As preferably, described supporting part is provided with buckle, covering part is provided with and the snap ring be clasped, supporting part and covering part are removably connected by buckle and snap ring.
As preferably, described positioning boss is anistree or 12 jiaos of nut shapes away from one end of supporting part.
As preferably, bending tube is provided with annular boss away from one end inwall parallel interval of connecting tube.
As preferably, connecting tube, positioning boss, supporting part and buckle are one-body molded, covering part and snap ring one-body molded.
As preferably, connecting tube, positioning boss, supporting part, buckle, covering part and snap ring all adopt pe100 material to make.
The invention has the beneficial effects as follows: site operation of the present invention is installed simple, only needs covering part to pull down, bellows is loaded, bending, then covering part is loaded onto, easy for installation, and covering part can repeat dismounting, and easy access, installation cost is low.The present invention adopts that pe100 material is one-body molded to be made, strength and stiffness are high, larger installation torsion can be born, gas leakage can not be caused because of fracture damage, possess very high safety and reliability, bellows can be prevented in addition to be corroded and corrosion, and it is elegant in appearance, merge mutually with interior decoration, do not destroy interior decoration, very practical.
