Description

FIELD OF THE INVENTION

The invention relates to the field of connection of pressure polymer pipes and can be used to connect polymer pipes of sewage and water supply to internal and external systems.

State of the art

Known shaped part of the sewer pipeline, comprising a housing with a rounded inner edge and sockets, the base of the socket located opposite the rounded inner edge is made with a groove whose width is equal to the inner diameter of the shaped part, and the outer diameter of the housing at the location of the groove is made equal to the outer diameter buildings (see AS USSR No. 969848, class E03F 3/04, publ. 10/30/1982).

The disadvantage of this shaped part is the low reliability and high cost of production of the shaped part.

Known shaped part made of plastic, including cylindrical pipes intersecting at right angles, having sockets with internal shelves, while the inner shelf of at least one socket is made inclined relative to its axis, and an oblique groove is made at the end of the socket on the inner surface, the bottom of which parallel to the inclined inner flange of the socket.

In the shaped part, the angle of inclination of the inner flange of the bell to its end is from 1 ° 15 'to 5 ° (see AS USSR No. 1268862, class F16L 47/00, E03F 3/04, published 07.11.1986 )

The disadvantage of this fittings is the low reliability.

The closest in technical essence and the achieved effect and adopted by the author for the prototype is a shaped part of a polymer water pipeline containing a threaded body, a sealing ring, a press-in sleeve, a nut, while it is equipped with a conical clamping ring with annular grooves in the form of ring teeth having a cut along the entire length of the ring and made without a groove in the inner diameter, with the possibility of tightening the nut to the stop and fixing the pipe with all the specified teeth of the conical clamping ring and, at the same time, the sealing ring is made elastic, and the press-in sleeve is made without protrusions (see Pat. RF No. 2259509 class. F16L 15/08, F16L 47/00, E03C 1/02, E03B 7/09).

The disadvantage of this fittings is the complexity of the design and the high cost of production.

Disclosure of invention

The technical result that can be achieved using the present invention is to simplify the design, reduce the cost of production, simplify installation work.

The technical result is achieved using a device for connecting pressure polymer pipes containing a shaped part having a socket with a shoulder and sealing, fixing teeth, while the shaped part at the end of the sockets is provided with grooves for the sealing rings, while the grooves in the shoulder are made of a larger diameter than the socket , with the possibility of installing pressure plastic pipes in the sockets of the shaped part through the sealing rings fixed by the teeth of the hinged clamp to the shoulder of the shaped part with a bolt.

Brief Description of the Drawings

Figure 1 shows a device for connecting pressure polymer pipes. Coupling with two sockets, into which different sections of the pressure polymer pipe are inserted with the pipe secured in the shaped part using clamps.

Figure 2 is the same, a clamp for attaching pressure polymer pipes in the shaped part.

Figure 3 shows a clamp for securing pressure polymer pipes in section.

The implementation of the invention

A device for connecting pressure polymer pipes contains a shaped part made in the form of a coupling 1, containing two sockets 2 with sockets 3 made on the end of the sockets 2 on both sides of the grooves 3 for mounting the sealing rings 4, while the sockets 2 have collars 5 for mounting the clamps 6, the latter with their teeth 7 fix the pressure polymer pipe 8, and the grooves 3 in the collars 5 are made of a larger diameter than the socket 2, with the possibility of installing pressure polymer pipes 8 in the pipes 2 of the shaped part through the sealing rings 4, closing PARTICULAR teeth 7 yoke 6, the latter consists of two parts 9 and 10, joined together by a hinge 11 and a bolt 12.

A device for connecting pressure plastic pipes is operated as follows.

O-rings 4 are inserted into grooves 3 made of a larger diameter than the socket 2 of the coupling 1, pressure polymer pipes 8 are inserted into the pipes 2 through the sealing rings 4, then parts 9 and 10 of the clamps 6 are pushed around the hinge 11 so that it is put on the shoulder 5, then the collar 6 is connected and tightened with a bolt 12 until the teeth 7 are inserted into the body of the polymer pressure pipe 8, in a similar way connecting all the fittings - couplings 1 of the pressure polymer pipe 8 and then the liquid is supplied into it, while the sealing rings 4 provide Seal tightness, and the teeth 7 of the clamps 6 prevent the arbitrary movement of the pipes 8, since one side of the clamp 6 is held by the shoulder 5 of the shaped part of the coupling 1.

The invention in comparison with the prototype and other known technical solutions has the following advantages:

- simplification of installation work;

- cheaper production;

- improving the reliability of the connection of pressure polymer pipes;

- simplification of the design;

- the exception of welding work at the installation site of the pipeline and special equipment;

- the possibility of the work of personnel with relatively low qualifications.

Claims (1)

A device for connecting pressure plastic pipes containing a shaped part having a socket with a shoulder and an o-ring, fixing teeth, characterized in that the shaped part at the end of the sockets is provided with grooves for the sealing rings, while the grooves in the collars are made of a larger diameter than the socket, with the ability to install pressure plastic pipes in the sockets of the shaped part through the sealing rings fixed by the teeth of the hinged clamp to the shoulder of the shaped part with a bolt.
