Description

The utility model relates to communication lines and is intended to provide sealing of the input into the room.

Known input for laying pipes and cables according to the patent of the Russian Federation for the invention No. 2120692, IPC Н02С 3/22, publ. 10/10/1998

This input is for communication input-output with a housing for cable passage, fixing and sealing elements. According to the invention, the sealing element is made in the form of an elastic sleeve, one end of which is fixedly mounted on the flange of the housing wall with a bandage, and the second is fixedly mounted on the sleeve. The sleeve has locking elements to prevent a reverse turn, and the housing wall has reciprocal locking elements.

Disadvantages: design complexity and inconvenience in assembly, the complexity of installation.

Known input means for laying pipes and cables according to the patent of the Russian Federation for invention No. 2319057, IPC F16L 15/02, publ. 06/20/2012

This means comprises an external frame having at least one sealing module installed inside the frame, which encloses a cable or pipe. The sealing module is divided in the longitudinal direction and is formed by peelable sheets to adapt the area of its channel with a cable or pipe. The sealing module is designed to fill the frame window with the expansion unit and has a dividing section for dividing it into two halves. The cut extends obliquely with respect to the longitudinal direction of the sealing module or relative to the longitudinal axis of the channel. When adapting the sealing module with a cable or pipe, one of the halves can be rotated 180 °. The module can adapt with the cable or pipe until half of the module comes into contact at the narrow end of the gap, with the half can be turned back 180 °, resulting in a uniform gap with complete sealing around the cable or pipe.

Disadvantage: design complexity.

Known input means for laying pipes and cables according to the patent of the Russian Federation for the invention No. 2453958, IPC H02G 3/22, publ. 06/20/2012, the prototype.

This input means relates to a wall inlet for laying cables, cable protection pipes or other wires through a wall of a building, in particular the outer wall of a building containing an external part with a base and a removable cover, the base with the cover forming a cavity and containing a pipe bent relative to its longitudinal axis for location in the cylindrical through hole of the wall, and in the cavity there is a sleeve coupling element for gas-tight connection of at least two ends of the cable, pipe or wire . To simplify the installation of the wall entry and ensure a reliable sealing function, the connecting element is divided along, and part of the connecting element is firmly connected to the base, and the pipe is equipped with a rubber-elastic shaped part for sealing from water splashes of at least one cable passed through the wall of the building, cable protection pipe or another wire relative to the through hole of the wall or pipe located in it.

Disadvantage: not effective sealing against dust, moisture and penetration of insects and rodents.

The task of creating a utility model: improving the tightness of the input.

Effect: increase the elasticity and elasticity of the pipe. The solution of these problems was achieved in a means of introducing a pipe or cable through a wall containing a metal housing in the form of a pipe with a flange for positioning in a cylindrical through hole of the wall, in that the pipe is made with a multilayer sleeve inside of a porous material.

Two to 30 layers of porous material may be applied. The porosity of the porous material increases from the outer wall to the axis of the nozzle.

The pores can be closed. Polytetrafluoroethylene may be used as the porous material. The pore size can be made from 0.05 mm to 5 mm. The flange can be made square with four holes. The flange can be made round with four holes. The flange can be made of aluminum.

The means for introducing and laying pipes and cables (Figs. 1-10) comprises a metal housing 1 comprising a pipe 2 and a flange 3 with a central hole 4 and side holes 5 at the corners. The corners are rounded with fillets 6 (in the first embodiment of FIG. 2 with a square flange). Perhaps the implementation of the pipe 2 with a round flange (Fig. 3).

The Central hole 4 can be made conical with a decrease in diameter from the inlet.

The angle γ = 7 ... 10 °.

The metal case 1 contains an end wall 7 made from the side opposite to the flange 3 with the second central hole 8 (Fig. 1). At the entrance to the Central hole 4 is a technological chamfer 9.

Inside the pipe 2, a sealing sleeve 10 is laid, made in the form of layers 11 of a porous material.

The porosity of the material of the layers 11 is from 30 to 70%, while the porosity of the layers 11 increases from the outer wall to the axis 00 or vice versa decreases. Pore sizes from 0.05 mm to 5 mm. The material of the layers 11 is polytetrafluoroethylene or ethylene vinyl acetate or any other porous material.

Along the axis of the sealing sleeve 10, a hole is made for the cable 12 (Fig. 1).

The total thickness of the layers 11 is from 30 to 50% of the inner diameter of the Central hole 4 of the pipe 2, i.e. the ratio is:

d = (0.5 ... 0.7) Dmax, where:

d is the inner diameter of the packing (diameter of the hole for the cable 12),

D ^max - external diameter of the packing (maximum diameter of the central hole 4).

It is possible to perform the sealing sleeve 10 in one layer or several layers. The number of layers 11 in the second embodiment is from 2 to 30. With a single-layer design, tightness is not always ensured, and the use of more than 30 layers 11 is impractical for technological reasons. The flange 3 can be made square (Fig. 2) with a Central hole 4 and four holes 5 at the corners with roundings 6.

Flange material 3 aluminum. The corners are rounded 6. The flange 3 can be made round (Fig. 3), and the side holes 5 have through slots 13 towards the side wall 14 of the flange 3.

The sealing sleeve 10 can be made of two parts 15 and 16, obtained by a longitudinal section 17 (Fig. 4 and 5).

In FIG. 6 is a drawing of a metal housing 1. It can be seen that a technological chamfer 9 is made at the entrance to the central hole 4, and a chamfer 18 at the entrance to the second central hole 8 to prevent cable seizure. In FIG. 7 shows the appearance of the metal housing 1.

The pores 19 (Fig. 9) in the layers 11 are made of variable size over the layers 11. The pore size 19 is in the range from 0.05 to 5 mm.

The input means is installed in the hole 20 of the wall 21 (Fig. 10). Cable 22 is passed through pipe 2. Layers 11 compress cable 22.

WORK WITH INPUT

When working (Fig. 10), the tool is installed in the hole 20 made in the wall 21. Through the pipe 2 pull the cable 22. The layers 11 of the sealing sleeve 10 are deformed and tightly compress the cable 22.

Application of the utility model allowed:

1. To increase the tightness of the connection;

2. Prevent moisture and dust from entering the room;

3. Prevent the penetration of rodents and insects.
