The utility model discloses the constitution includes: the wall-penetrating pipe is inserted into the outer wall (1), a first flange (3) and a second flange (4) are sleeved on the wall-penetrating pipe, and the second flange is pressed on the first flange and is fixed with the first flange through a bolt; the wall penetrating pipe is sequentially sleeved with a first fixing ring (32), a pressing ring (33) and a second fixing ring (34) to be pressed at a gap between the first flange and the wall penetrating pipe. The utility model is used for the wall body pipe is sealed.

Description

Wall pipe sealing device

The technical field is as follows:

the utility model relates to a wall body pipe sealing device.

Background art:

at present, the ash leakage condition exists at the through-wall position of a large-package through-wall pipe, and the through-wall pipe is not well fixed.

The utility model has the following contents:

an object of the utility model is to provide a wall body pipe sealing device to solve the problem that above-mentioned exists.

The above purpose is realized by the following technical scheme:

a wall tube sealing device comprises: the wall penetrating pipe penetrates into the outer wall, a first flange and a second flange are sleeved on the wall penetrating pipe, and the second flange is pressed on the first flange and is fixed with the first flange through a bolt;

the wall penetrating pipe is sequentially sleeved with a first fixing ring, a pressing ring and a second fixing ring to press the first flange and the gap between the wall penetrating pipes.

The first flange of the wall pipe sealing device is provided with a fixing bolt inserted into a gap between the outer wall and the wall pipe.

And a flexible sealing ring is sleeved between the second flange and the wall penetrating pipe.

Has the advantages that:

1. first flange and second flange are located the surface of wall pipe, the rear end of first flange is provided with the bolt, the bolt sets up to the integrated into one piece structure with first flange, can prevent to appear leaking, the displacement appears easily and freely flexible problem, after adorning first flange, the wall pipe that will dock with being located the wall pipe butt joint of outer wall, dock second flange and first flange laminating afterwards, make the second screw position on first screw on the first flange and the second flange correspond each other, insert the inside of first screw and second screw with the screw again, make first flange and second flange fixed connection through the screw, thereby it is more stable when docking each other between the wall pipe, difficult emergence freely stretches out and draws back.

2. The utility model discloses utilize being connected of first flange and wall body and being connected of first flange and second flange, effectively fixed with the wall pipe. And the sealing effect of the through-wall part is ensured by using the sealing material between the first flange and the second flange.

Description of the drawings:

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic structural view of a first flange of the present invention;

FIG. 3 is a schematic structural view of a second flange of the present invention;

in the figure: 1. an outer wall; 2. a through-wall pipe; 3. a first flange; 4. a second flange; 31. fixing the bolt; 32. a first retainer ring; 33. pressing a ring; 34. a second retainer ring; 35. a first flange screw hole; 41. a second flange screw hole; 42. a screw; 43. a flexible seal ring.

The specific implementation mode is as follows:

example 1:

referring to fig. 1 to 3, a wall pipe sealing device comprises: the wall-penetrating pipe comprises an outer wall 1 and a wall-penetrating pipe 2, wherein the wall-penetrating pipe penetrates into the outer wall, a first flange 3 and a second flange 4 are sleeved on the wall-penetrating pipe, and the second flange is pressed on the first flange and fixed with the first flange through a bolt;

the wall penetrating pipe is sequentially sleeved with a first fixing ring 32, a pressing ring 33 and a second fixing ring 34 to be pressed in a gap between the first flange and the wall penetrating pipe.

The first flange is provided with a fixing bolt 31 inserted into a gap between the outer wall and the wall penetrating pipe.

A flexible sealing ring 43 is sleeved between the second flange and the wall penetrating pipe。

Firstly, a first flange 3 is sleeved on a wall penetrating pipe 2 and then pushed forwards, the first flange 3 is fixed with an outer wall 1 and the wall penetrating pipe 2 through a bolt 31 at the rear end of the first flange 3, then a first fixing ring 32 is stretched and bound to the outer surface of the wall penetrating pipe 2 through elasticity, the first fixing ring 32 is made of elastic material, a press ring 33 is sleeved on the outer surface of the wall penetrating pipe 2, finally a second fixing ring 34 is bound to the outer surface of the wall penetrating pipe 2 through elasticity, so that the press ring 33 is clamped and fixed by the first fixing ring 32 and the second fixing ring 34, the wall penetrating pipe 2 and the first flange 3 can be firmer through the first fixing ring 32, the second fixing ring 34 and the press ring 33 between the wall penetrating pipe 2 and the first flange 3, and the wall penetrating pipe 2 can not displace, after installing first flange 3, the wall pipe 2 that will need the butt joint docks with the wall pipe 2 that is located outer wall 1, dock second flange 4 and first flange 3 laminating afterwards, make first screw 35 on the first flange 3 and the second screw 41 position on the second flange 4 correspond each other, insert the inside of first screw 35 and second screw 41 with screw 42 again, make first flange 3 and second flange 4 fixed connection through the screw thread, thereby it is more stable when docking each other between the wall pipe 2, difficult emergence freely stretches out and draws back, flexible sealing washer 43 specifically is an HNBR hydrogenated nitrile rubber material, through set up flexible sealing washer 43 in the inside of second flange 4, can make better fixed between wall pipe 2 and the sealing device, also can prevent simultaneously that wall pipe 2 is inside to leak.
