Description

TAP DEVICE

to the PIPELINE

The utility model relates to the construction of connecting nodes of pipelines, namely to "-devices for connecting branches to the pipeline and can be used in various sectors of the economy for pipelines with different pressure of the working medium.

A device is known for attaching branch pipes to a pipeline, consisting of a sealing packing box covering the branch, a fixed branch pipe of which is rigidly connected to a clamping element covering the pipe, and mounted on a connecting sleeve abutted to the pipe, made of separate sectors pulled together by an elastic ring, and sectors placed in an elastic ring the plane of the coupling element, equipped with half rings (see ed. certificate of the USSR No. 1252601, class F 16L 41/04, publ. 23.08.86,

bull. No. 31).

However, the known device has insufficient reliability of the seal and low-tech in the manufacture.

Also known is a system for performing a tap from a pipe with a fluid substance under load, comprising an intake passage having an external thread and thrust devices. The end section of the outlet pipe can be axially inserted into the passage and has at least one toroidal gasket. The lock nut rests on the shoulder of the pipe and

MPK6R16b 41/08

can be screwed onto the thread of the groove (see French Patent No. 2702820, class F 16L 41/04, F 16L 41/16, publ. 23.09.94).

The disadvantages of the known system include the insufficient reliability of collapse and the complexity of its design.

Closest to the proposed combination of features is a device for connecting the bends to the pipeline, containing a branch seat with a nozzle, detachably connected to the pipeline by means of a clamp with a fastening element, and having on the mating side a cylindrical concave surface with a curvature corresponding to the radius of the outer surface of the pipeline, covering an intermediate elastic ring the indicated surface of the pipeline from the side of the branch hole in the wall of the latter. On the inner surface

of the retraction seat, a cylindrical recess eccentric with respect to this surface is made, the width of which is greater than the diameter of the branch hole of the pipeline and less than the width of the concave surface of the retraction seat, while the intermediate elastic ring is located in the cylindrical recess (see ed. certificate of the USSR No. 1499048, class F 16L 41/08, publ. 07.08.89, bull. No. 29).

But this device also has insufficient sealing reliability, and is also inconvenient during installation and dismantling and is limited to use for pipelines with the same tolerances of the outer diameter.

The problem, the solution of which the proposed utility model is aimed at, is to increase the reliability of the seal when connecting the bends to the pipeline and to improve the ease of installation and dismantling of the device.

To solve this problem, in the device for connecting the bends to the pipeline, containing the outlet saddle with a cylindrical groove on the inner surface and a pipe, is detachably connected to the pipeline by means of a clamp with a fastening element, and having a cylindrical concave surface with a curvature corresponding to the radius of the outer surface of the pipeline , covering through the intermediate elastic ring the specified surface of the pipeline from the side of the branch hole in the wall of the latter, with According to a useful model, the cylindrical undercut on the inner surface of the retraction seat has a bevel in the form of a reverse truncated cone, and the intermediate elastic ring is made with a protrusion having the same shape and dimensions with a cylindrical undercut on the inner surface of the retraction saddle, while on the surfaces of the intermediate elastic ring from the side annular grooves are made in the branch wall in the pipeline wall and on the side adjacent to the outlet seat, and eyelets are made on the outlet seat with the possibility of interaction ystviya a fastener clamp.

Moreover, the clamp can be made of sheet material of a given thickness.

The presence on the cylindrical undercut of the saddle for removing the bevel in the form of a reverse truncated cone, and on the intermediate elastic ring, a protrusion having the same shape and

dimensions with a cylindrical groove, allows you to securely hold the elastic ring.

The execution of annular grooves on both sides of the elastic ring increases the reliability of the seal by creating local sealed sections on the outer surface of the pipeline from the branch hole and from the side adjacent to the outlet saddle.

And the execution of the eye retraction on the saddle, with the possibility of interaction with the fastening element of the clamp, improves the convenience of installation and dismantling of the device.

The implementation of the clamp from sheet material allows you to use the device for pipelines with various shells of the outer diameter.

In Fig.1 shows a device for connecting the taps to the pipeline, General view; on the. figure 2 - saddle retraction, a perspective view; in Fig.Z - intermediate elastic ring, axonometry.

The drawings have the following digital positions: 1 - retraction saddle; 2 - a cylindrical recess on the inner surface of the seat retraction 1; 3 - pipe; 4 - pipeline; 5 - a collar; 6 - fastening element of the clamp 5; 7 - a cylindrical concave surface on the abutted side of the seat retraction 1; 8 - intermediate intermediate elastic ring; 9 - branch hole in the wall of the pipe 4; 10 - bevel in the form of a reverse truncated cone on a cylindrical undercut 2; 11 - a protrusion made on an intermediate elastic ring 8; 12 - an annular groove made on the surface of the intermediate elastic ring 8 from the side of the branch hole 9 in

pipe wall 4; 13 - an annular groove made on the surface of the intermediate elastic ring 8 from the side adjacent to the outlet pipe 1; 14 - eyes.

The device for connecting the taps to the pipeline contains (Fig. 1) a seat saddle 1 with a cylindrical undercut 2 on the inner surface and a pipe 3. The seat saddle 1 is detachably connected to the pipe 4 by means of a clamp 5 with a fastening element 6 and has a cylindrical concave surface 7 on the mating side with a curvature corresponding to the radius of the outer surface of the pipeline 4. A cylindrical concave surface 7 covers through the intermediate elastic ring 8 the outer surface of the pipeline 4 from the side of the branch Stia 9 in the pipe wall 4.

The cylindrical undercut 2 has a bevel 10 (FIGS. 1 and 2) in the form of an inverse truncated cone. The intermediate elastic ring 8 is made with a protrusion And (fig.Z) having the same shape and dimensions with a cylindrical recess 2. On the surfaces of the intermediate elastic ring 8 from the side of the branch hole 9 in the pipe wall 4 and from the side adjacent to the outlet seat 1, are made annular grooves 12 and 13.

On the saddle of the outlet 1, eyes 14 are made with the possibility of interaction with the fastening element 6 of the clamp 5.

A device for connecting bends to the pipeline works as follows.

When the device is installed, the fixing element 6 of the clamp 5 is removed from the eyes 14 of the outlet seat 1. Then, the outlet saddle 1 with the clamp 5 is laid on the pipe 4, combining the pipe 3 with the branch hole 9 in the pipe wall 4. Using the fixing element 6, the clamp 5 is brought together eyes 14 with each other. This increases the pressing force of the intermediate elastic ring 8 to the outer surface of the pipe 4, providing reliable sealing of the device.

The end section of the outlet pipe (not shown) is screwed into the pipe 3.

Dismantling is carried out in the reverse order, releasing the fastener 6, distributing the clamp 5 and the eyes 14, and removing the device from the pipeline 4.
