Detailed Description

As shown in fig. 1 and 2, the fireproof pipeline plugging device comprises a plugging device arranged between a perforation 7 and a pipeline 5 in a structure 1, in the embodiment, the plugging device comprises plugging pieces arranged at two sides of the perforation, a through hole 13 is arranged in the middle of each plugging piece, the pipeline 5 penetrates through the through hole 13 and the perforation 7 in the structure 1, the two plugging pieces are connected through a spring 8, and the two plugging pieces are pressed against two sides of the structure 1 by the spring 8.

In this embodiment, as shown in fig. 2, the plugging member includes a sealing portion 3 and an assembling portion 9, the assembling portion 9 extends into the through hole 7 of the structure 1, an expansion connecting member 11 is disposed outside the assembling portion 9, the spring 8 is sleeved on the expansion connecting member 11 and fixed, and each expansion connecting member 11 extends out of the through hole 7 of the structure 1 through a conduit 4.

The expansion connecting piece 11 is an elastic rubber piece wrapped and fixed outside the assembly part, a gas storage cavity is formed in the expansion connecting piece, the gas storage cavity is inflated through the conduit 4 to enable the expansion connecting piece to expand, and the conduit 4 extends out of the structure 1 from one side.

In this embodiment, the external portion of the expansion connecting member 11 is provided with a limiting convex ring 112, after the expansion connecting member 11 is inflated and expanded, the protruding limiting convex ring 112 is used for fixing the spring 8 assembled outside the expansion connecting member 11, as long as the expansion connecting member is always in an expanded state, the spring is always in a stretched state, and the plugging members on both sides can be pressed against the outer wall surface of the structure by the tensile force generated by the spring.

Wherein, the outside of pipe 4 stretches out the end and sets up a one-way inflation valve (not shown), and when the pipe 4 of one side appears leaking gas because flame is destroyed, the inflation connecting piece volume diminishes this moment, and the spacing arch of original inflation can slowly retract, and the spring is loosened from one end this moment, and two shutoff pieces just no longer have the pressure this moment, have along pipeline axial displacement's ability.

In this embodiment, an inflatable sealing element 2 is embedded in one surface of the sealing part 3 opposite to the structure, a connecting pipe 12 is arranged inside the inflatable sealing element 2, an inflatable plugging ring 6 is arranged on the inner wall of a through hole 13 of the plugging element, the inflatable plugging ring 6 is connected with the connecting pipe 12, the interior of the inflatable sealing element 2 is inflated and then expanded, as long as the plugging element is pressed against the outer wall surface of the structure all the time, the gas in the inflatable sealing element can enter the inflatable plugging ring, so that the inflatable plugging ring is expanded to be in contact with the outer wall surface of the pipeline for sealing, and meanwhile, the inflatable sealing element is in contact with the structure, so that the sealing.

In this embodiment, aerify shutoff ring 6 and aerify sealing member 2 and all adopt the elastic rubber material that has resilience ability to make, the resilience force of aerifing shutoff ring 6 is greater than the resilience force of aerifing sealing member, when taking off the shutoff piece alone, aerify the intraannular gas of shutoff and just can enter into automatically in the inflatable sealing member, the inflatable sealing member just is in the inflation state, in case the shutoff piece is accomplished the installation, so under spring action for the inflatable sealing member is squashed, and aerify the shutoff ring then can expand, with this purpose that reaches the shutoff.

In this embodiment, the limit protruding ring 112 is made of hard rubber material, so as to increase the limit capability.

As shown in fig. 3, more than one concave hole is arranged in the middle of the inflatable sealing element 2, an ejection spring 22 is arranged in each concave hole, one end of the ejection spring 22 is fixed with the contact surface of a structure by glue when the inflatable sealing element is installed, and the other end of the ejection spring is arranged in each concave hole and is in contact with a plugging element;

after the spring pine takes off, the shutoff piece of both sides alright freely removes along the pipeline, ejection spring restores deformation in the twinkling of an eye this moment, because after the shutoff piece installation is accomplished, the shutoff piece can make ejection spring all be in compression state, so in case spring and shutoff piece pine take off, so under the effect of ejection spring and inflatable seal spare, the shutoff piece pops out fast, if there is flame on the shutoff piece this moment, so can take away flame from structure department, at the shutoff piece along the pipeline removal in-process, if there is flame on the pipeline, through the physical friction mode, also can utilize the shutoff piece to get rid of the flame of upper end, reach the purpose of putting out a fire.

The invention has the beneficial effects that: the invention has good plugging effect, is more flexible to use, does not need to select according to the size, and can be applied to more occasions. Meanwhile, the part of the plugging device, which is in contact with the flame, can be quickly separated from the plugging device body, so that the flame is prevented from being transmitted to another space along the plugging device, and the aim of safely isolating the fire is fulfilled.

The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
