Description

This invention relates to shipbuilding, in particular, to the tread protection structures of ship pipelines.

The purpose of the invention is to increase the serviceability of the device by providing axial movement of the tread in a water pressure pipe.

Figure 1 presents the proposed device, a General view; figure 2 - the mutual arrangement of the annular sleeve of the glass and the tread; on fig.Z10

the flange 24 and the lid 4 are not shown) The inner sealed cavity in which the upper end of the rod 6 is located is designated B. Radial clearances b are provided between the inner surface of the annular tongue 22 and the faces of the nut 12, allowing the nut 12 to rotate.

The installation of the device is carried out as follows.

On the rod 6 install the nut 15 and the washer 16, and in the groove 13

the relative position of the annular drill-15 cap 4 - gasket. 14, after which

that glass with gasket and tread; figure 4 - removable deaf sleeve cover glass.

The tread device of the ship pipeline contains pipeline 1, a cup 2 with an annular collar 3 and a cap 4, in the axial hole 5 of which a threaded rod 6 is installed with a faceted head 7 connected to the bottom 20

the rod is screwed into the cap and, at its end 8, wind up the nut 12 and the washer 11. Then the conical end 8 is screwed into the hole 10 of the protector 9 up to the stop and rigidly connected by tightening the nut 12, After the projector 9 is installed in the upper position (up to the stop nuts 12 in the cover 4) the cover 4 is fixed on the glass 2, set

25, the conductor 1 / and is sealed by tightening the gasket nut 15 with the gasket 14. Thus, the device is reset to its original operating position. Deaf bushing 23 in the device is used

With a tapered end 8 with a tread 9, there is a deaf cylindrical threaded hole 10 provided at the end of the tread 9. At the bottom end of the rod 6, pressure pins 30 are installed at the end of the tread 9, usually with water pressure in pipe 11 and a nut 12. (Cavity B) more than 8-10 kg / cm.

25, the conductor 1 / and is sealed by tightening the gasket nut 15 with the gasket 14. Thus, the device is reset to its original operating position. Deaf bushing 23 in the device is used

5 in the lid 4 there is an annular groove 13 in which a sealing gasket 14 is formed, which forms a sealing device of the rod 6 with nut 15 and washer 16, which is connected to the cup 2 and the internal cavities of the pipeline 1 and cup by means of a flexible conductor 17 and fastener 18 2 are designated A and B, respectively. Burth 3 can be made figured with a thinned edge 19 forming an annular gap a with the tread (FIG. 2), in addition.

the shaped shoulder 3 can be made with 45 nut 12 and the dead sleeve 23 with a triangle-shaped cross-section, the ring sleeve 20 of which is provided with a figured sealing gasket 21 (FIG. 3). On the cover 4 there is an annular protrusion 22 with an external thread, by means of which a removable sleeve 23 with a flange 24 and a faceted head 25 is attached to it (ynj50

lead to the original sealed position. If the device does not have a sleeve 23 in the device, the fastener 18 is dismounted before the rod 6 rotates. After the protector 9 has been completely developed, as a result of its repeated axial movement, the cover 4 is removed and the new protector is installed.

flange 24 and cover 4 is not shown). The inner sealed cavity, in which the upper end of the rod 6 is located, is designated B. Radial clearances b are provided between the inner surface of the annular projection 22 and the faces of the nut 12, which allow the nut 12 to rotate.

The installation of the device is carried out as follows.

the rod is screwed into the cap and, at its end 8, the nut 12 and the washer 11 are screwed. Then the conical end 8 is screwed into the hole 10 of the tread 9 as far as it will go and they are rigidly connected by tightening the nut 12, After the projector 9 is installed in the upper position (up to the stop nuts 12 in the cover 4) the cover 4 is fixed on the glass 2, set

usually with water pressure in the pipeline (cavity B) of more than 8-10 kg / cm.

The device works in the following way.

After the end of the tread 9, which is located in the cavity A, is removed, the dead sleeve 23 is removed, the nut 12 is removed, for example, with a cap end key, it is fixed and the head 7 is rotated 6 together with the protector 9. During this period leakage through the gasket 14 is possible. since the work is performed at the working pressure of water in the pipeline. After the tread 9 is moved along the axis to the calculated size of the nut 12 and the dead sleeve 23,

lead to the original sealed position. If the device does not have a sleeve 23 in the device, the fastener 18 is dismounted before the rod 6 rotates. After the protector 9 has been completely developed, as a result of its repeated axial movement, the cover 4 is removed and the new protector is installed.
