Pipeline axial buffer device is set, and when flare line produces shock loading, the impact that can absorb flare line is carried Lotus, when pipeline axial buffer device is installed；The preload of applying >=pipeline static axial stress, so as to meet pipeline to axial direction Spacing conduit saddle and the displacement request of fixed pipe bracket；By pipeline axial buffer device, can be with effective protection flare piping and support Steel construction.

Further being improved by, fluting tapered end being additionally provided with the outer set and mark closely screw, its effect is to fix tune Section screw mandrel and overcoat, prevent screw thread from getting loose

Further it is improved by, the pipeline axial buffer device also has the second gusset；Second gusset, overcoat and Riser constitutes pipeline axial buffer device body.

Further it is improved by, the regulation screw mandrel prolongs axially extending has a protuberance.

Specific embodiment

The anti-axial impact pipe holder of torch pipeline of the present utility model includes conduit saddle body 1 and conduit saddle base 2, such as Fig. 1 Shown, the conduit saddle base 2 is fixed and supports the conduit saddle body 1, and the conduit saddle base 2 is made up of base 3 and radial stop 4； Also include several pipeline axial buffer devices 5 to be arranged on the base 3, and averagely split in the both sides of the base 3；Institute The bottom for stating pipeline axial buffer device 5 has riser 6, for supporting the overcoat 7 for being located at 6 top of the riser；In the overcoat 7 Being provided with disc spring and 8 being oriented to, the periphery that 8 are oriented in the disc spring is provided with disc spring 9, leads in the disc spring 9 and the disc spring To 8 composition disc spring groups 10；It is additionally provided with, in the overcoat 7, the regulation screw mandrel 11 screwed with the disc spring group 10.

The conduit saddle body 1 includes reinforcement riser 12, reinforcement arc plate 13, the first riser 14, baffle plate 15, gusset 16（Such as Shown in Fig. 7）With the second riser 17, the base plate 18 on the base 3 is also included（As shown in Figure 2,3）；The base plate 18 With 5 interval setting of pipeline axial buffer device；Fluting tapered end is additionally provided with the overcoat 7 marks closely screw 19；As Fig. 4-6 Shown, the pipeline axial buffer device 5 also has the second gusset 20；Second gusset 20, overcoat 7 and riser 6 constitute pipeline Axial buffer device body 21；The radial stop 4 and the pipeline axial buffer device 5 are weldingly fixed on the base 3；The fire The anti-axial impact pipe holder in torch pipe road has 8 pipeline axial buffer devices 5；The regulation screw mandrel 11 prolongs axially extending has a protrusion Portion 22, the effect of protuberance 22 are to adjust the strong point of screw mandrel as a rotation.
