[0021] Please refer to Figures 1-4The utility model provides a technical scheme: an anti -explosion pipeline compensator, including compensator main part 1, two flanges 2 and two bases 9, two flanges 2 top and bottom are fixedly connected with fixed block 5 respectively, and the top and bottom two adjacent fixed block 5 between slidingly connected with connecting rod 6, and the top and bottom two connecting rod 6 between fixedly connected with first spring 7, two flanges 2 front side and rear side are fixedly connected with L type slide bar 10 respectively, two bases 9 surface all respectively are set with two sliding slot 11, and the surface sliding connection of slide bar has guide rod 12, and the surface fixedly connected with guide spring 13 of guide rod 12, and guide spring 13 one end is fixedly connected with the inside of sliding slot 11, and L type slide bar 10 bottom is slidably connected with the inside of sliding slot 11, and the surface fixedly connected with four pressure blocks 14 of compensator main part 1, and the inside fixedly connected with four cavities 15 of flange 2, and four pressure blocks 14 with four cavities 15 position correspond, and the inside fixedly connected with second spring 17 of cavity 15, and the fixedly connected with sliding block 16 of pressure block 14 away from flange 2, and the inside sliding connection of sliding block 16 both sides with cavity 15, and the fixedly connected with second spring 17 one end of sliding block 16 one end, when compensator main part 1 installs on the pipeline, when pipeline temperature is too high, will make compensator main part 1 department's expansion joint to both sides expansion, make two flanges 2 to both sides movement, to drive the L type slide bar 10 and fixed block 5 on the surface of flange 2 to both sides movement, to this drive guide spring 13 compression, when moving to certain position, can drive the first spring 7 between two connecting rods 6 stretch, and then reduce thermal pressure, to be able to reduce the influence that transverse thermal pressure brings, simultaneously will because temperature is too high and the expansion joint of compensator main part 1 to all around expansion, to drive pressure block 14 to cavity 15 inside movement, to this drive sliding block 16 in cavity 15 movement, and then compress second spring 17, to reduce the influence of all around thermal pressure to compensator main part 1.

[0022] As Figure 1 Shown, the outside fixedly connected with protective sleeve 3 of compensator main part 1, and the surface of protective sleeve 3 is set with a plurality of heat dissipation holes 4, and protective sleeve 3 is a kind of high elasticity heat-resistant rubber, and it has higher elasticity, so when expansion, it can avoid because the hard material of protective sleeve 3 cannot stretch, influence the movement of compensator main part 1, and heat dissipation hole 4 can dissipate the heat on the surface of compensator main part 1, reduce the influence of temperature to compensator main part 1 again.

[0023] As Figure 1 Shown, the fixedly connected with anti -drop block 8 of top and bottom two connecting rod 6 away from first spring 7 one end, can avoid flange 2 to fall off.

[0024] Working principle: when using, when compensator main part 1 installs on the pipeline, the heat dissipation hole 4 on the surface of protective sleeve 3 can first carry out certain heat dissipation;

[0025] But when the pipe temperature is too high, the expansion joint of the compensator body 1 will expand to both sides, so that the two flanges 2 move to both sides, so as to drive the L-shaped slide rod 10 and the fixed block 5 on the surface of the flange 2 to move to both sides, so as to drive the guide spring 13 to be compressed, when moving to the anti-dropping block 8, the first spring 7 between the two connecting rods 6 can be stretched, thereby reducing the thermal pressure again, so as to reduce the influence of the transverse thermal pressure, at the same time, the expansion joint of the compensator body 1 will expand to all around due to the temperature being too high, so as to drive the pressing block 14 to move into the cavity 15, so as to drive the sliding block 16 to move in the cavity 15, thereby compressing the second spring 17, so as to reduce the influence of the thermal pressure on all around on the compensator body 1;

[0026] And when expanding, the protective sleeve 3 has high elasticity, so that when expanding, the influence of the protective sleeve 3 which cannot stretch due to hard material on the movement of the compensator body 1 can be avoided.

[0027] Through the above operation, the explosion of the compensator body 1 caused by the temperature being too high can be reduced at each position of the compensator body 1.
