The invention relates to piping technology and can be used as a movable compensating connection of pipelines of various purposes.

A ball joint is known for pipelines, allowing for their limited displacement relative to each other and containing two nozzles, one of which ends with a camera with spherical inserts covering the spherical tip of the other nozzle {I.

The disadvantage of this connection is the impossibility of compensating the displacement of the axes of the connected pipelines.

Closest to the present invention is a hinge compensating device for pipelines, comprising a housing with an internal spherical surface, a spherical hinge, an emphasis made composite of telescopically connected spring-loaded elements with spherical tips, and sealing elements 2.

The disadvantages of this device are a large number of moving parts, which reduces the reliability of the device, and a large number of sealing elements that increase the likelihood of the device depressurizing. In addition, the large axial dimensions increase the metal structure. All this limits the possibility of using the known device in small-sized structures.

The purpose of the invention is to simplify the design and reduce material consumption.

The goal is achieved by the fact that in an articulated compensating device for pipelines, including a body with an internal spherical surface, an emphasis with an external spherical surface, a spherical hinge and sealing elements, an internal spherical surface is placed in the rest, which is eccentrically relative to the external one, while the external spherical surface of the emphasis the mate with the body, and internally with a spherical hinge.

FIG. I shows the device, a longitudinal section; in fig. 2 - position

component parts of the device when the axis of the nozzle is shifted.

The hinge compensating device for pipelines consists of a body I with an internal spherical surface having a center at the point Oi; a spherical hinge 2 with an external spherical surface having a center at the point Og, an emphasis 3 with an external and internal spherical surface, and the external surface is conjugated to the housing 1, has a center at the point O |, and the internal one is conjugated with a spherical hinge 2 - at the point Oj. Sealing of conjugated spheres is accomplished using, for example, rubber

rings 4 and 5.

The compensating device operates as follows.

By turning the spherical hinge 2 relative to the center Og, the misalignment of the axes of the connected pipelines is compensated.

When compensating for misalignment D of the connected pipelines (Fig. 2), the stop 3 rotates an angle a relative to the center PI, and its outer spherical surface slides along the spherical surface of the housing I, and internally over the surface of the spherical hinge 2. At the same time, the center O describes a circle with a radius I, centered at point Ob, and the axis of the spherical hinge 2, which owns the point Os, performs a plane-parallel movement, is displaced relative to the axis of the body I, which owns the point O |, by the value of Al.sina.

The new position of the nozzles of the housing I and the spherical hinge 2 allows to connect the pipelines with the misalignment D,

This preserves the possibility of compensating for angular displacements of pipelines in the process of work.

 Such an embodiment of the hinge compensating device reduces its axial dimensions, reduces the number of movable mating parts, which leads to a simplification of the device design, to a decrease in metal intensity and an increase in the reliability of the structure operation. All this allows the use of a compensating device in small-sized structures.
