Problems solved by technology

[0002] The pipeline compensator is mainly used to compensate the thermal expansion and contraction of the pipeline due to temperature changes. When the pipeline is heated, the pipeline will generate thermal stress. Excessive thermal stress will cause the rupture of the pipeline and affect the normal production of the pipeline. Therefore, It is necessary to use a compensator to enhance the thermal stress resistance of the pipe body, but when the existing compensator is actually used, it simply relies on the corrugated expansion block set by itself to enhance the strength and toughness of the compensator itself, so as to realize For the improvement of thermal stress resistance, this method is too simple, and the effect of resisting thermal stress is not ideal.

Embodiment 1

[0030] see figure 1 and figure 2 , a safety type explosion-proof compensator, including a pipe body 1 and a pipe 11, the pipe 11 is arranged inside the port of the pipe body 1, the surface of the pipe 11 and the pipe body 1 is provided with a flange 10, and the inner wall of the pipe body 1 is provided with a hole Cavity 3, the inner wall of the cavity 3 is provided with a compression component 2, the interior of the pipe body 1 is provided with an expansion tube 18, the expansion tube 18 and the compression component 2 are provided with a rubber cushion 7, and the compression component 2 includes a compression plate 201 , movable bar 202 and spring 203, one side of anti-pressure plate 201 is fixedly connected with the end face of movable bar 202, and one end of spring 203 is arranged on the side of anti-pressure plate 201, and the end face of anti-pressure plate 201 and the inner wall of cavity 3 Flexible connection, the end of the spring 203 away from the anti-pressure pla...

Embodiment 2

[0033] see figure 1 and figure 2 , the end face of the movable rod 202 is fixedly connected with a piston block 5, the inner wall of the pipe body 1 is provided with an empty chamber 4, the piston block 5 is movably connected with the inner wall of the empty chamber 4, and the inner wall of the empty chamber 4 is fixedly installed with a rubber air cushion 6. The pad 7 is fixedly mounted on the inner wall of the cavity 3, one side of the rubber cushion 7 is movably attached to the side of the pressure-resistant plate 201 and one side is in contact with the outer wall of the expansion tube 18,

[0034] The difference from Embodiment 1 is that a piston block 5 is added on the end face of the movable rod 202 to facilitate the use of the piston block 5 to squeeze the gas inside the empty chamber 4, and cooperate with the rubber air cushion 6 inside the upper empty chamber 4 to shrink under pressure to weaken the movement. The active force on the rod 202 weakens the influence of ...

Embodiment 3

[0036] see figure 1 , image 3 and Figure 4 The inside of the side wall of the pipe body 1 is provided with a sealing assembly 12, the surface of the pipe 11 is provided with a septum 14 suitable for the sealing assembly 12, the surface of the pipe 11 is provided with a sealing groove 13 for installing the septum 14, and the sealing assembly 12 Including airbag 121, conduit 122 and rubber inflatable pad 123, conduit 122 is fixedly installed between the airbag 121 and rubber inflatable pad 123, both airbag 121 and rubber inflatable pad 123 are fixedly installed in the inner wall of pipe body 1, and the surface of pipe 11 is set There is a first sealing ring 15, and the inner wall of the pipe body 1 is provided with a second sealing ring 16, and the first sealing ring 15 and the second sealing ring 16 are fitted together.

[0037] The difference from Embodiment 2 is that a sealing assembly 12 is provided in the side wall of the pipe body 1, so that the air bag 121 in the seal...

Abstract

The invention relates to the technical field of anti-explosion compensators, and particularly discloses a safety type anti-explosion compensator which comprises a pipe body and a pipeline, the pipeline is arranged in a port of the pipe body, flange plates are arranged on the surfaces of the pipeline and the pipe body, a cavity is formed in the inner wall of the pipe body, a pressure-resistant assembly is arranged on the inner wall of the cavity, and the pressure-resistant assembly is arranged on the inner wall of the cavity. An expansion pipe is arranged in the pipe body, a rubber cushion is arranged between the expansion pipe and the compression-resistant assembly, and the compression-resistant assembly comprises a compression-resistant plate, a movable rod and a spring; the cavity is formed in the inner wall of the pipe body and used for installing the compression-resistant assembly, so that a movable rod and a spring in the compression-resistant assembly are used for providing supporting force for the compression-resistant plate, when the compression-resistant plate is subjected to thermal stress transmitted to a rubber cushion from the expansion pipe, the compression-resistant plate can transmit the force to the movable rod, meanwhile, the spring is compressed, and the compression-resistant plate is prevented from being damaged. The elastic force of the spring is used for eliminating thermal stress, and the effect of enhancing the resistance of the pipe body to thermal stress is achieved.
